"What kind of rubbish are you?" This question might normally cause anger, but in Shanghai it was brought about weary complaints over the past few months. On July 1st, the city introduced strict rubbish-sorting regulations that are expected to be used as a model for our country. Citizens must divide their waste into four separate categories and put it into specific public bins. They must do so at scheduled times, when monitors are present to ensure that rules are obeyed and to examine the nature of one's rubbish.
Violators could be hit with fines of up to 200 yuan ($29). For repeat violators, the city can add black marks to their credit records, making it harder for them to obtain hank loans or even buy train tickets.
Shanghai authorities are responding to obvious environmental problem. It produces 9 million tons of garbage a year. But like other cities in china, it lacks a recycling system. Instead, it has relied on rubbish pickers to pick out whatever can be reused. This has limits. As people get wealthier, fewer of them want to do such dirty work. The waste, meanwhile, just keeps piling up. China produces 80 billion pairs of one-off chopsticks a year.
Many citizens appear to support the idea of recycling in general but are frustrated by the details. Rubbish must be divided according to whether it is food, recyclable, dry or hazardous(有害的), the distinctions among which can be confusing, though there are apps to help work it out. Some have complained about the rules surrounding food waste. They must put it straight in the required public bin, forcing them to tear open plastic bags and toss(投掷）it by hand, Most annoying are the short periods for throwing trash, typically a couple of hours, morning and evening. Along with the monitors at the bins, this means that people go at around the same time and can keep an eye on what is being thrown out; no one wants to look bad.
（1）What's the purpose of Paragraph 1?
A. To complain about rubbish dividing.
B. To explain the four categories of the waste.
C. To introduce the rules on waste sorting.
D. To show the goal of rubbish, sorting regulations.

A. People who don't pay for train tickets.
B. People who argue with the monitors.
C. People who obtain bank loans.
D. People who are against the regulations.
（3）What makes the citizens upset most about the rules?
A. Complex distinction among the four categories of rubbish.
B. Short scheduled time for tossing rubbish.
C. Being observed by monitors when throwing the garbage.
D. Being fined when blamed due to improper behavior.
（4）What can be the best title for the text?
A. A Restart of Waste-sorting
B. A New Age of Garbage Classification

2．阅读理解
A recent study finds that the dirt on the ground is likely to worsen climate change. Researchers have shown that warmer temperatures are heating the soil, which is causing microbes (微生物) to become more active and release more of the soil's carbon into the atmosphere. These soil changes can potentially contribute to even higher temperatures.
Scientists studied device readings, soil measurements, plant growth details and satellite observations from around the world. Their work is the most complete study on the subject.
They found a sharp increase in carbon released into the atmosphere by bacteria and fungi (真菌) in soil from 1990 to 2014. Researchers explain that the carbon comes from the dead plants and leaves the microbes eat. As temperatures rise, the microbes eat more. And the more they eat, the more carbon can be made into carbon dioxide and released into the atmosphere.
This uncontrolled cycle speeds up and intensifies climate change. Overall, soil releases about nine times more carbon than human activities. But that is part of a natural cycle: the amount of carbon released into the air is about equal to the carbon oceans and plants take in.
However, carbon released from fossil fuel causes an imbalance. Burning coal, oil and natural gas puts more carbon into the atmosphere than nature can take in. The additional carbon heats the air and soil. And as the air and soil get hotter, the earth will release more carbon than it has been holding.
If something isn't done, we are really in trouble. Proper soil conservation can help keep more carbon in soil. Conservation methods include avoiding turning the soil, covering off-season crops and leaving crop deposits on the ground.
（1）Which word can best describe the scientists' research data?
A.Rich.
B.Rare.
C.Limited.
D.Difficult.
（2）What does the underlined word "intensifies" in Paragraph 4 mean?
A.Causes.
B.Demands.
C.Strengthens.
D.Shows.
（3）What mainly causes the soil's temperature to rise?
A.Active bacteria.
B.Human activities.
C.The overuses of soil.
D.The wastes of fossil fuels.
（4）What can be a suitable title for the passage?
A.Warmer soil and more carbon.
B.The soil and the environment.
C.The microbes and the temperatures.
D.Hotter air and warmer environment.
【答案】（1）A
（2）C
（3）B
（4）A
【解析】【分析】本文是一篇说明文，介绍了人类燃烧燃料造成的土壤变化可能导致地球更高的温度。
（1）考查推理判断。根据第二段中的“Scientists studied device readings, soil measurements,
plant growth details and satellite observations from around the world. Their work is the most complete study on the subject.”科学家们研究了来自世界各地的设备读数、土壤测量、植物生长细节和卫星观测数据。他们的工作是对这一课题最全面的研究。故选A。
（2）考查词义猜测。根据第四段中的“This uncontrolled cycle speeds up and intensifies climate chan ge.”可知，and 为并列连词，即intensifies应与之前的speeds up 为同义词。speed up 意为“加速”，C项strengthen 意为“加强；增强”可为同义词。故选C。
（3）考查细节理解。根据第五段中的“However, carbon released from fossil fuel causes an imbalance. Burning coal, oil and natural gas puts more carbon into the atmosphere than nature can take in. The additional carbon heats the air and soil. And as the air and soil get hotter, the earth will release more carbon than it has been holding”然而，化石燃料释放的碳造成了不平衡。燃烧煤炭、石油和天然气向大气中排放的碳超过了自然所能吸收的量。额外的碳使空气和土壤升温。随着空气和土壤变得越来越热，地球释放出的碳将超过它所承受的量。可知，人类的一系列燃烧燃料的行为是土壤温度上升的主要原因。故选B。
（4）考查主旨大意。根据第一段中的“soil changes can potentially contribute to even higher temperatures.”中间段落进行阐述分析原因和结果。末段提出了“Proper soil conservation can help keep more carbon in soil.”并提供了建议。因此标题关键词需有 soil, carbon等核心词。A 项Warmer soil and more carbon.符合分析。故选A。
【点评】本题考点涉及细节理解，词义猜测和主旨大意三个题型的考查，是一篇环保类阅读，考生需要准确掌握细节信息，同时根据上下文的逻辑关系，进行分析，推理，概括和归纳，从而选出正确答案。
3．阅读理解
The negative (负面的) health effects of sleep shortages during the week can't be changed by marathon weekend sleep sessions, according to a new study.
Researchers have long known that routine sleep deprivation (缺乏) can cause weight gain and increase other health risks, including diabetes. But there are still some people who hope that shutting off the alarm on Saturday and Sunday will repay the weekly sleep debt and remove any ill effects.
The research, published in Current Biology, ruins those hopes. Despite complete freedom to sleep in and nap during a weekend recovery period, participants in a sleep laboratory who were limited to five hours of sleep on weekdays gained nearly three pounds over two weeks and experienced metabolic disruption (代谢紊乱) that would increase their risk for diabetes over the long term. While weekend recovery sleep had some benefits after a single week of inadequate sleep, those gains were wiped out when people returned right to their same sleep schedule the next Monday.
"If there are benefits of catch-up sleep, they're gone when you go back to your routine. It's very short-lived," said Kenneth Wright, who led the research. "These health effects are long-term. It's kind of like smoking once was — people would smoke and wouldn't see an immediate effect on their health, but people will say now that smoking is not a healthy lifestyle choice. I think sleep is in the early stage of where smoking used to be."
Wright said that the study suggests people should prioritize sleep — cutting out the optional "sleep stealers" such as watching television shows or spending time on electronic equipment. Even when people don't have a choice about losing sleep due to child-care responsibilities or job schedules, they should think about prioritizing sleep in the same way they would think about a healthy diet or exercise.
（1）What had the researchers already known before doing the new research?
A. The actual benefits of weekend recovery sleep.
B. Harm to health caused by the lack of routine sleep.
C. People's habit of shutting off the alarm during holidays.
D. The relationship between body weight and sleep amount.
（2）Kenneth Wright mentioned smoking to _________.
A. call on smokers to completely abandon smoking
B. advise people to go to sleep when they want to smoke
C. show people have known the harm brought by smoking
D. show people will someday notice the bad effects of sleep deprivation
（3）What does the underlined word "prioritize" probably mean?
A.Have a low opinion of something.
B.Increase the amount of something.
C.Cut down something that isn't necessary any more.
D.Treat something as being more important than others.
（4）What can be the best title for the text?
A.Weekend Catch-up Sleep Is a Lie
B.Bad Sleep Habits Are Harmful to Health
C.A New Study Has an Unexpected Discovery
D.Advantages and Disadvantages of Catch-up Sleep
【答案】（1）B
（2）D
（3）D
（4）A
【解析】【分析】本文是一篇说明文，作者通过一项研究与对比举例的方法让大家明白周末马拉松式的“补觉”并不能扭转工作日睡眠不足对健康的负面影响。人们应该把睡眠放在优先地位。
（1）考查细节理解。根据第二段中的“Researchers have long known that routine sleep deprivation (缺乏) can cause weight gain and increase other health risks, inclu ding diabetes”研究人员很早就知道长期的睡眠缺乏会导致体重增加和像糖尿病这样的健康风险，可知，人们很早就知道长期睡眠不足会给身体带来的危害。故选B。
（2）考查推理判断。根据第四段中Kenneth Wright说的最后两句话可知：长期睡眠不足给健康造成的危害是长期的，就像曾经的抽烟习惯一样——人们抽烟，没有看到立即的效应，但是现在人们会说抽烟是不健康的生活方式。睡眠不足就像是早期的抽烟一样。也就是说作者用这个比喻是想让大家知道终究会有一天人们会注意到睡眠不足带来的坏处。故
选D。
（3）考查词义猜测。划线单词后有一个破折后，起解释说明的作用。由破折后的句意：减少不必要的“睡眠小偷”式行为，比如看电视节目或者花时间在电子设备上。可知，我们需要把睡眠放在优先的地位。也就是说要把睡眠看的比看电视节目、看电子设备等等这些行为更重要。故选D。
（4）考查主旨大意。第一段就说明了文章中心。第一段段意为：一项发人深省的新研究表明，周末马拉松式的“补觉”并不能扭转工作日睡眠不足对健康的负面影响。也就是说周末的补觉是一个谎言。故选A。
【点评】本题考点涉及细节理解，词义猜测，推理判断和主旨大意四个题型的考查，是一篇健康类阅读，要求考生在捕捉细节信息的基础上，进一步根据上下文的逻辑关系，进行分析，推理，概括和归纳，从而选出正确答案。
4．阅读理解
Even if you've never been to Phoenix, you know this about the place It's hot. From June to September, the temperature can easily surpass the century mark. But that doesn't stop hikers from attempting the 1.3-mile hiking to the top of the city's famed Camelback Mountain. Signs warn that the trail is "extremely difficult". If you continue, a posted checklist suggests at least a liter of water per person. And if you're still not stopped, another sign farther up declares: "If you're halfway through your water, turn around!"
Unfortunately, many people to not take the warnings seriously. Fortunate y, Scott Cullymore does. The 53-year-old Cullymore can be found hiking up and down Camelback a couple of times a day, giving out cold bottles of water to worn-out hikers. He has helped hydrate so many hikers that he has earned a heavenly nickname: the Water Angel.
Cullymore was on Camelback Mountain one day in 2015 when a British tourist died after being lost for nearly six hours in the July heat. That experience inspired him to start helping people caught unaware by the cruelty of Mother Nature. "They underestimate the mountain, and they overestimate what they can do, and they get themselves in trouble." he warned.
One hiker who was offered water agrees. "You think you know the heat, but then you get out here in the desert and it surrounds you like a blanket," said Austin Hill, who was hiking with a high school friend. They were lucky, he said pointing to Cullymore. "We ran into this Good Samaritan here." And with that, the Water Angel goes in search of another hiker in need.
（1）What is the first paragraph mainly about?
A. The risks involved in the hiking.
B. The seriousness of the warnings.
C. The distribution of signs that warn hikers.
D. The influence of the temperature on hikers.（2）Why did some hikers on Camelback Mountain get in trouble?
A. They were not well trained in hiking.
B. They forgot to take enough water with them.
C. They were too optimistic about the situation.
D. They were not fit enough to hike the mountain.
（3）What can we know about Austin Hill?
A. He agreed to help others.
B. He was saved by Cullymore.
C. He hiked alone in the desert.
D. He regretted taking a blanket.
（4）What is the best title for the text?
A. The Camelback Mountain
B. Surviving the Heat
C. Hikers in Need
D. The Water Angel
【答案】（1）A
（2）C
（3）B
（4）D
【解析】【分析】本文是一篇记叙文，远足者低估夏日的Camelback Mountain 同时高估自己的能力，所以在远足途中遇到麻烦，Cullymore了解情况后决定帮助他们。Cullymore通过在炎炎夏日给那些远足者提供水而被人们亲切地称为“水天使”。
（1）考查段落大意。根据第一段中的”Fr om June to September, the temperature can easily surpass the century mark“；”Signs warn that the trail is ‘extremely difficult’“；”If you continue, a posted checklist suggests at least a liter of water per person. “和“If you're halfway through your water, tur n around!”可知在夏天去Camelback Mountain远足是非常艰难的，原因有两个：一个是温度很高，另一个是水。故选A。
（2）考查细节理解。根据第三段中的”They underestimate the mountain, and they overestimate what they can do, and they get themselves in trouble.“可知人们低估了这座山，同时高估了自己的能力，因此他们陷入麻烦中，即对情况感到过于乐观导致他们涉险。故选C。
（3）考查推理判断。根据最后一段中的”They were lucky, he said pointing to Cullymore. ‘We ran into this Good Samaritan here.’”可知Austin Hill说他们很幸运，因为他们遇到了Cullymore这个乐善好施的人，故推测Cullymore救了他。故选B。
（4）考查主旨大意。根据第二段中的“He has helped hydrate so many hikers that he has earned a heavenly n ickname: the Water Angel.”和最后一段中的“And with that, the Water Angel goes in search of another hiker in need.”以及文章主要内容可知，本文主要叙述了Cullymore 通过在山上给登山者发水来帮助他们，从而得到“水天使”的昵称，即本文主要讲述“水天使”的故事。故选D。
【点评】本题考点涉及细节理解，推理判断，段落大意和主旨大意四个题型的考查，是一篇故事类阅读，要求考生在捕捉细节信息的基础上，进一步根据上下文的逻辑关系，进行分析，推理，概括和归纳，从而选出正确答案。
5．阅读理解
DNA analysis has revealed family relationships between more than 10 generations of Stone Age people at megalithic (巨石的) tombs in Ireland and Sweden.
The evidence suggests that megaliths, prehistoric large stone structures, sometimes acted as graves for family groups in northwestern Europe thousands of years ago. The latest findings throw new light on the origins and social structure of the groups that built megaliths in this region—a history that has long been hidden in mystery.
For their study, the international team of researchers analyzed the genomes—the complete set
of genetic material in a cell—of 24 Stone Age individuals from five megalithic burial sites in Ireland, Scotland and Gotland, a large Swedish island in the Baltic Sea.
This analysis showed that many of the individuals buried at each megalith, who all lived between 3,800 B.C. and 2,600 B.C., according to radiocarbon-dating of their remains, were closely related via family ties.
The results also showed that the individuals buried at the megaliths were related to Neolithic farmers in northern and western Europe but genetically distinct from other hunter-gatherers. This was particularly noticeable at the Ansarve site on the island of Gotland.
"The people buried in the Ansarve tomb are remarkably different on a genetic level compared to the individuals dug out from hunter-gather contexts, showing that the burial tradition in this megalithic tomb, which lasted for over 700 years, was performed by distinct groups with roots in the European Neolithic expansion," Magdalena Fraser, co-first author from Uppsala University, said in the statement.
（1）What's the significance of the new findings?
A. It reveals the family ties between people in Ireland and Sweden.
B. It implies that many people buried in the tombs were closely related.
C. It indicates the long-hidden mystery concerning DNA analysis.
D. It suggests that the megaliths became tombs thousands of years ago.
（2）How did the researchers reach their findings?
A.By interviewing individuals.
B.By travelling to different regions.
C.By analyzing genes.
D.By studying the burial sites.
（3）Which is true according to the latest findings?
A.Some people buried in the tombs were related to farmers.
B.Few people buried in the tombs were genetically different.
C.All the people buried at megaliths had family relationships.
D.People buried in the Ansarve tomb were dug out 700 years later.
（4）What's the main idea of this passage?
A.Megaliths served as tombs thousands of years ago.
B.People buried at the megaliths were recently analyzed.
https://www.doczj.com/doc/455023184.html,test findings shed light on a mystery about burials.
D.Stone-Age people in Ireland and Sweden had close ties.

6．阅读理解
Alison Malmon was trapping up (完成) the end of her freshman year at the University of Pennsylvania, US when she got the news: Her older brother Brian, a student at Columbia University, was suffering from mental illness.
Inspired by this, Malmon formed a group at her university to empower (使能够) students to talk openly about mental health. It soon blossomed into a national organization that today has more than 450 campus chapters. Leaders with the organization spend their time talking with college students about the pressure that today's young people face.
"What you hear often is just a need to be perfect," said Malmon, "and a need to present oneself as perfect."
And a new study in the UK proved that this need for perfectionism is simply part of today's society. In the study, two researchers studied more than 40,000 students from the US, Canada, and the UK. They found that what they called "socially prescribed(社会定向型的) perfectionism" increased by a third between 1989 and 2016.
Lead researcher Thomas Curran said that while so many of today's young people try to present a perfect appearance online, social media isn't the only reason behind this trend. Instead, he said, it may be driven by competition in modern society, meaning young people can't avoid being sorted and ranked in both education and employment. That comes from new norms(准则) like greater numbers of college students, standardized testing and parenting that increasingly emphasizes success in education.
For example, in 1976, half of high school seniors expected to get a college degree of some kind. By 2008, more than 80 percent expected the same. The researchers also said changes in parenting styles over the last two decades might have had an impact. As parents feel increased
pressure to raise successful children, they in turn pass their "achievement anxieties" onto their kids through "excessive(过多的) involvement in their child's routines, activities or emotions"
Those in the mental health community like Malmon say they're concerned about the impact the culture of perfectionism has on mental health on campuses. "Mental health has truly become this generation's social justice issue," she said. "It's our job to equip them with the tools and to let people know that it's not their fault."
（1）What is the article mainly about?
A. The effects of the culture of perfectionism.
B. Research into the trend of perfectionism.
C. A group dedicated to helping people stay mentally healthy.
D. Various pressures that today's young people are facing.
（2）What inspired Alison Malmon to start a group related to mental health?
A.Her brother's mental illness.
B.Her project during the freshman year.
C.The pressure she had experienced.
D.Her strong interest in mental health.
（3）What does Malmon think is a way to help young people manage the pressure of perfectionism?
A.Enabling them to know what is to blame for their pressure.
B.Lowering their expectations of themselves.
C.Reducing parents involvement in their children's life.
D.Making them aware of what true social justice is.
【答案】（1）B
（2）A
（3）A

7．阅读理解
Some things should just be common knowledge by now. The Earth isn't flat. Nope, your hair and nails don't grow after you die. The holes at the top of Bic biro pens are there so that, if you swallow one accidentally, you can still breathe and won't choke to death. It's debatable whether that last one there is common knowledge or not. A quick Google search of the fact, rewritten as a question, shows articles addressing this point going back several years, with the latest (re)appearing just this week over on ScienceAlert. We suppose it's one of those things that come up from time to time, like what would happen if you attack Yellowstone with a nuclear weapon (not much, as it turns out).
If you jump over to Bic's website, under their FAQs (frequently asked questions), it quite clearly states: "The reason that some BIC? pens have a hole in their cap is to prevent the cap from completely obstructing the airway if accidentally breathed in. This is requested by the international safety standards ISO11540, except for in cases where the cap is considered too large to be a choking risk."
That's rather lovely of them. In appreciation of their want to not kill off their more clumsy customers, we thought we'd share a few more random facts about Bic that are probably going to come up in a pub quiz one day. Did you know, for example, that each Bic ballpoint pen can produce at least 2 kilometers (1.2 miles) of ink before it begins to run out? In fact, in 2018, 7,250 kilometers (4,505 miles) of writing tests on such pens were carried out on ballpoint pens, gel pens(中性笔), and rollers to make sure they worked to the highest standard.
The best part of the Bic site, however, is this rather curious fact: "100 percent of pen balls are made through a highly-controlled process." As opposed to a highly uncontrolled process, involving explosions and bouncy castles and total chaos, we suppose.
（1）Why does the author mention the case of Yellowstone?
A. To list the facts.
B. To prove his point.
C. To compare the two situations.
D. To emphasize the importance of safety.
（2）What does the underlined word "obstructing" in paragraph 2 mean?
A. Block.
B. Open.
C. Transform.
D. Narrow.
（3）Why were the writing tests on pens carried out?
A. To work out their lifespan.
B. To assure their good quality.
C. To prove some random facts.
D. To compare different pens with each other.（4）In what tone does the author develop the text?
A. Critical.
B. Acid.
C. Humorous.
D. Serious.
【答案】（1）B
（2）A
（3）B
（4）C

Eating red meat is linked to cancer and heart disease, but are the risks big enough to justify
giving up juicy burgers and delicious steaks? Probably not, according to researchers who reviewed data from 12 clinical trials involving about 54,000 people. In a series of controversial papers, the researchers argue that the increased health risks tied to red meat are small and uncertain, and that cutting back likely wouldn't be worth it for people who enjoy meat.
Those conclusions go against established medical advice. They were swiftly attacked by a group of famous U.S. scientists who took the unusual step of trying to stop the papers from being published until their criticisms were addressed.
The new work does not say red or processed meats like hot dogs and bacon are healthy, or that people should eat more of them. The team's reviews of past studies generally support the ties to cancer, heart disease and other bad health outcomes. But the authors say the evidence is weak, and that there's not much certainty meat is really the cause, since other diet and lifestyle factors could be at play.
If the latest example of how divisive nutrition research has become, with its uncertainties leaving the door open for conflicting advice. Critics say findings often aren't backed by strong evidence. Defenders counter that nutrition studies can rarely be conclusive because of the difficulty of measuring the effects of any single food, but that methods have improved.
Based on their analyses, the researchers said people do not have to cut back for health reasons. But they noted that their own advice is weak, and acknowledged that they didn't consider factors such as animal welfare and the environment. Indeed, the case that meat production is bad for animal welfare and the environment is stronger than the case that it's bad for human health, according to an editorial that accompanies the report.
Not all of the report authors agreed with its conclusions. Three of the 14 researchers said they support reducing red and processed meats. A coauthor of one of the reviews is also among those who called for a publication delay.
Those who pushed to postpone publication also questioned why certain studies were included in the reviews while others were left out.
As for his own diet, Dr. Gordon Guyatt, a member of the international research team that conducted the reviews, said he no longer thinks red or processed meats have significant health risks. But he said he still avoids them out of habit, and for animal welfare and environmental reasons.
（1）What is the author's purpose in writing the passage?
A.To introduce a new relationship between health and eating red meat.
B.To urge more people to keep away from eating red meat regularly.
C.To present a new controversial view on impacts of eating red meat.
D.To criticize nutrition studies for lacking of conclusive evidence.
（2）What is the author's attitude towards the new research?
A.Doubtful.
B.Positive.
C.Disapproving.
D.Objective.
（3）Guyatt's avoiding red meats has the weakest connection with_______.
A.health risks
B.diet habits
C.animal welfare
D.environmental protection
（4）What can we learn from the recent research?
A.Red meats don't have significant health risks.
B.Reducing meat consumption will be worth it.
C.The report authors have reached a consensus.
D.Consuming red meat will do good to health.
【答案】（1）C
（2）D
（3）A
（4）A
【解析】【分析】本文是一篇议论文，作者对于吃红肉是否与癌症和心脏病有关引用了研究发现、结果、例子等客观数据和事实来写这篇文章。
（1）考查推理判断。根据第一段中的“Eating red meat is linked to cancer and heart disease, but are the risks big enough to justify giving up juicy burgers and delicious steaks? Probably not, according to researchers...”可知，吃红肉与癌症和心脏病有关，但是否这些风险大到足以让你放弃多汁的汉堡和美味的牛排呢？根据研究人员研究发现，答案是不一定，引导出了一个关于吃红肉有争议的新观点，故选C。
（2）考查推理判断。根据“according to researchers who reviewed data”，“ the researchers argue that”，“ Those conclusions go against established medical advice”，“ The team's reviews of past studies”“ the latest example”，“ Based on their analyses”等等，可知作者主要引用研究发现、结果、例子等客观数据和事实来写这篇文章，可知作者对新研究的态度是客观的，故选D。
（3）考查细节理解。根据最后一段中的“But he said he still avoids them out of habit, and for animal welfare and environmen tal reasons.”但他说避免吃红肉是出于习惯，也是为了保护动物福利和环境，没有说是健康风险问题，可以判断Guyatt避免吃红肉与健康风险的关系最弱，故选A。
（4）考查推理判断。根据第三段中的“The new work does not say red or processed meats like hot dogs and bacon are healthy, or that people should eat more of them. The team's reviews of past studies generally support the ties to cancer, heart disease and other bad health outcomes. But the authors say the evidence is weak...”这项新研究并没有说红肉或加工肉类如热狗和熏肉是健康的，也没有说人们应该多吃。以往研究通常支持红肉与癌症、心脏病和其他不良健康的联系，但这项研究的作者说这个证据是站不住脚的，可以推断红肉没有明显的健康风险，故选A。
【点评】本题考点涉及细节理解和推理判断两个题型的考查，是一篇健康类阅读，考生需要准确掌握细节信息，并根据上下文进行逻辑推理，从而选出正确答案。

City trees grow faster and die younger than trees in rural forestry, a new study finds. Over their lifetimes, then, urban trees will likely absorb less CO2 from the air thah forest trees.
As we all know, the earth would be freezing or burning hot without CO2. However, CO2is a greenhouse gas, meaning it traps energy from the sun as/heat. That makes temperatures near the ground rise. Human activities, especially the widespread burning-of fossil(化石)fuels, have been sending extra greenhouse gases into the air. This has led to a rise in average temperatures across the globe.
Studies had shown forests readily absorb CO2, but there hadn't been much data on whether city trees grow, die and absorb CO2at the same rate as forest trees do. So some researchers decided to find out.
To figure out how quickly trees were growing, researchers tracked their diameters (the width of their trunks) between 2005 and 2014. A tree's diameter increases as it grows, just as a person's waist size increases as they gain weight. About half the weight of a tree is carbon, research has shown. Most of the rest is water. Over the nine years' tracking, the researchers found city trees absorbed four times as much carbon from the air as forest trees. However, they were twice as likely to die. So over the lifetime of each type of tree, forest trees actually absorbed more CO2.
City trees grew faster because they had less competition for light from their neighbors. In a forest, trees tend to grow close together, shading their neighbors. Street trees also benefit from higher levels of nitrogen (氮)in rainwater. Nitrogen helps plants grow. Waste gases from gas-burning cars also contain nitrogen, thus enriching city air with nitrogen. Later, rainwater may wash much of it to the ground. Some street trees may also have better access to water than trees in the country because the underground water pipes can leak.
（1）What can he known about CO2 from paragraph 2?
A. It is one of the side effects of greenhouses.
B. It greatly accelerates the process of global warming.
C. It results from the widespread burning of fossil fuels.
D. It prevents the earth from becoming unsuitable to live on.
（2）Why did researchers track the diameters of trees?
A. To know about their growth rates.
B. To find out how much they weigh.
C. To check whether they were healthy.
D. To assess the carbon amounts in them.
（3）What advantage do city trees have over forest trees?
A. They are more likely to access growth promoters.
B. They can enjoy more water coming from the air.
C. They can enjoy more shade from neighbors.
D. They are better at competing for light.
（4）What will probably be talked about if the passage is continued?
A. How urban trees can live longer.
B. Why city living makes trees die young.
C. How trees respond to dry soil conditions.
D. Why faster-growing trees absorb more CO2.【答案】（1）D
（2）A
（3）A
（4）B
【解析】【分析】本文是一篇说明文，一项新的研究发现：与长在森林中的树木相比，城市里的树木长得更快，但死得更早。
（1）考查推理判断。根据第二段中的“the earth would be freezing or burning hot without CO2.”可知，如果没有二氧化碳，地球将会极冷或极热。可以推断，二氧化碳可以防止地球变得不适合居住。故选D。
（2）考查细节理解。根据第四段中的“To figure on how quickly trees were growin g, researchers tracked their diameters.”可知，研究人员监测树木的直径是为了了解树木的生长速度。故选A。
（3）考查细节理解。根据最后一段中的“Street trees also benefit from higher levels of nitrogen (氮）in rainwater. Nitrogen helps plants grow. Waste gases from gas-burning cars also contain nitrogen, thus enriching city air with nitrogen. Later, rainwater may wash much of it to the ground.”可知，与生长在森林中的树木相比，城市里的树木长得更快是因为它们无需与邻近的树木争夺光照，也能得到更多的氮量，还更容易得到水。光、氮和水都可以促进树木的生长。由此可以推断，城市里的树木比森林中的树木更可能获得生长促进剂。故选A。
（4）考查推理判断。文章首句就提到了一项新的研究结果：城市里的树木比森林中的树木长得更快，但死得更早；文章第三段说到“以前有研究表明森林会吸收二氧化碳，但是城市里的树木的生长、死亡和吸收二氧化碳的速度是否跟森林中的树木一样，这方面的数据不多。因此一些研究人员决定弄清楚”；文章第四段再次介绍了他们的研究发现：城市里的树木比森林中的树木长得更快，但死得更早；文章最后一段介绍了城市里的树木比森林中的树木生长得更快的几个原因。由此可以推断，文章接下来很可能就要介绍城市里的树木死得更早的原因。故选B。

11．阅读理解
On average, Americans spend about 10 hours a day in front of a computer or other electronic devices and less than 30 minutes a day outdoors. That is a claim made by David Strayer, a professor of psychology at the University of Utah. In his 2017 TED Talk, Strayer explained that all this time spent with technology is making our brains tired.
Using an electronic device to answer emails, listen to the news and look at Facebook puts a lot of pressure on the front of the brain, which, Strayer explains , is important for critical (有判断力的)thinking , problem-solving and decision-making.
So, it is important to give the brain a rest. And being in naure, Strayer claims, helps get a tired brain away from too much technology. More than 15,000 campers from around the world attended an international camping festival in September. That is when friends and family take time off and escape to nature for several days. They take walks, climb, explore, swim, sleep, eat and play. Camping may be just what a tired brain needs.
Take Carl for example .He lives in West Virginia and enjoys camping. He says that staying
outdoors makes him feel at ease. It also prepares him for the work he must do. Kate Somers is another example who also lives in West Virginia. She says she enjoys camping with her husband and two children. She calls it a “regenerative” experience.
At the University of Utah, David Strayer has studied both short-term and long-term exposure to nature. He found that spending short amounts of time in nature without technology does calm the brain and helps it to remember better. However, he found, it is the long-term contact with nature that does the most good. He and his research team found that spending three days in nature without any technology is enough time for the brain to fully relax and reset itself.
（1）What is David Strayer's opinion?
A. Americans dislike outdoor activities.
B. Electronic equipment should be quitted.
C. New technologies are a double-edged sword.
D. Electronic equipment brings great convenience.
（2）Why does Strayer insist we go outdoors?
A. To try another lifestyle.
B. To refresh our brain.
C. To make better decisions.
D. To play with our family and friends.
（3）What does the underlined word “regenerative” mean?
A. Reborn
B. Memorable
C. Remarkable
D. Tiring
（4）Which is the proper title for the passage?
A. Electronic Equipment Harms the Brain.
B. Good Rest Develops Good Memory.
C. Tips on Using New Technologies.
D. Being in Nature Is Good for the Brain.
【答案】（1）C
（2）B
（3）A
（4）D

12．（2019?北京）阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项。
By the end of the century, if not sooner, the world's oceans will be bluer and greener thanks to a warming climate, according to a new study.
At the heart of the phenomenon lie tiny marine microorganisms (海洋微生物) called phytoplankton. Because of the way light reflects off the organisms, these phytoplankton create colourful patterns at the ocean surface. Ocean colour varies from green to blue, depending on the type and concentration of phytoplankton. Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the ocean's appearance.
Phytoplankton live at the ocean surface, where they pull carbon dioxide (二氧化碳) into the ocean while giving off oxygen. When these organisms die, they bury carbon in the deep ocean, an important process that helps to regulate the global climate. But phytoplankton are vulnerable to the ocean's warming trend. Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunlight and carbon dioxide to grow, but also nutrients.
Stephanie Dutkiewicz, a scientist in MIT's Center for Global Change Science, built a climate model that projects changes to the oceans throughout the century. In a world that warms up by 3℃, it found that multiple changes to the colour of the oceans would occur. The model projects that currently blue areas with little phytoplankton could become even bluer. But in some waters, such as those of the Arctic, a warming will make conditions riper for phytoplankton, and these areas will turn greener. "Not only are the quantities of phytoplankton in the ocean changing." she said, "but the type of phytoplankton is changing."
（1）What are the first two paragraphs mainly about?
A. The various patterns at the ocean surface.
B. The cause of the changes in ocean colour.
C. The way light reflects off marine organisms.
D. The efforts to fuel the growth of phytoplankton.
（2）What does the underlined word "vulnerable" in Paragraph 3 probably mean?
A. Sensitive
B. Beneficial
C. Significant
D. Unnoticeable
（3）What can we learn from the passage?
A. Phytoplankton play a declining role in the marine ecosystem.
B. Dutkiewicz's model aims to project phytoplankton changes
C. Phytoplankton have been used to control global climate
D. Oceans with more phytoplankton may appear greener.
（4）What is the main purpose of the passage?
A. To assess the consequences of ocean colour changes
B. To analyse the composition of the ocean food chain
C. To explain the effects of climate change on oceans
D. To introduce a new method to study phytoplankton
【答案】（1）B
（2）A
（3）D
（4）C
【解析】【分析】本文是一篇说明文，一项最新研究表明，由于气候变暖，世界海洋将会变得更蓝、更绿。这一现象是因为一种叫做浮游植物的微小海洋微生物，因为光线反射的作用，它们在海洋表面形成了五颜六色的图案。但是浮游植物很容易受到海洋变暖趋势的影响，气候变暖会改变海洋的主要特征，并影响浮游植物的生长。
（1）段落大意题。第一段“By the end of the century. If not sooner, the world's oceans will be bluer and greener thanks to a warming climate, according to a new study.”可知，到本世纪末，一项新的研究表明，由于气候变暖，如果不尽快的话，世界上的海洋将会变得更蓝、更绿。再根据第二段中的“At the heart phenomenon lie tiny marine microor ganisms called phytoplankton. Becaust of the way light reflects off the organisms ,these phytoplanktons create colourful patterns at the ocean surface. Ocean colour varies from green to blue, depending on the type and concentration”可知，这种现象的核心是一种叫做浮游植物的微小海洋微生物，在光线的作用下在海洋表面形成了五颜六色的图案。海洋的颜色从绿色到蓝色不等，这取决于海洋的类型和浮游植物浓度。由此可推断出这两段主要叙述了海洋生物是海洋颜色变化的原因。故选B。
（2）词义猜测题。根据第三段中的“Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunshine and carbon dioxide to grow, but also nutrients.”可知，气候变暖会改变海洋的主要特征，并会影响浮游植物的生长。由此可判断“But phytoplankton are vulnerable to the ocean's wamning trend”可知，浮游植物很容易受到海洋变暖趋势的影响。故选A。
（3）推理判断题。根据第四段中的“The model projects that currently blue areas with little phytoplankton could become even bluer. But in some waters ,such as those of the Arctic, a warming will make conditions riper for phytoplankton, and these areas will turn greener”,可知Dutkiewicz的模型预测，目前只有少量浮游植物的蓝色区域可能会变得更蓝。但是在一些水域，比如北极，气候变暖会使浮游植物的生长条件更加成熟，而这些水域会变得更绿了”。由此可推断，浮游植物的生长条件更加成熟，浮游动植物就更多了，这些水域会变得更绿了。故选D。
（4）主旨大意题。第一段提出文章的主旨“By the end of the century. If not sooner, the world's oceans will be bluer and greener thanks to a warming climate, according to a new study.”可知到本世纪末。一项新的研究表明，由于气候变暖，如果不尽快的话，世界上的海洋将会变得更蓝、更绿。再结合第三段“But phytoplankt on are vulnerable to the ocean's warning trendWarming changes key characteristics of the ocean and can affect phytoplankton growth, …”可知，“浮游植物很容易受到海洋警告趋势的影响，变暖改变了海洋的关键特征，并能影响
