Ⅰ.阅读理解
A
How does a sunset work？We love to look at one，but Jolanda Blackwell wanted her eighth-graders to really think about it and question.
So Blackwell had her students watch a video of a sunset as part of a physics lesson on motion.“I asked them：‘So what’s moving？And why？’”Blackwell says.Some thought the sun was moving；others knew that a sunset is the result of the Earth spinning around on its axis.“Usually，my biggest challenge is trying to keep them patient，”she says.“They just have so many burning questions.”
“Every day，we meet new information，”says Charan Ranganath，a psychologist.Ranganath was curious to know why we keep some information and forget other things.So he got 19 volunteers and asked them to review more than 100 questions.When the participants’ curiosity was aroused，the parts of their brains that regulate pleasure and reward lit up.Curious minds also showed increased activity in the brain，which is involved in the creation of memories.
“Curious brains are better at learning not only about the subject at hand but also dull information.This is a phenomenon teachers can use in the classroom.”says Evie Malaia，a professor.“Say a kid wants to be an astronaut，”she says.“Well，how do you link that goal with learning multiplication tables(乘法表)？”“A teacher may choose to ask her class an interesting problem that involves space exploration，”Malaia says.Students may remember the answer to the problem，but they’ll also remember how they found the answer through multiplication.
What Ranganath wants to know most is why some people seem naturally more curious than others.Lots of factors，including stress，aging and certain drugs can affect dopamine(多巴胺) processing in the brain.“If we could figure these things out，we could help those who may just seem bored，”Ranganath says.
Blackwell says she doesn’t have to deal with that problem too often.She says her students love exploring the mysterious unknowns in science：What happens when a car crashes？How do rainbows work?
“I tell my kids there’s no dumb questions，”Blackwell says.“That’s science：asking questions and seeking answers.”
1．What challenge did Blackwell have in class?
A．The students were often burnt by accident.
B．The students were asking too many questions.
C．The students couldn’t concentrate in her class.
D．The students couldn’t answer questions gently.
2．If we are curious，we .
A．will desire to be rewarded
B．may forget undesirable things more easily
C．may memorize something better
D．will have more energy to do outdoor activities
3．Malaia gave the example of a kid in Paragraph 4 to prove .
A．multiplication tables are difficult to learn
B．math is the basis knowledge for space exploration
C．becoming an astronaut is a dream of many kids
D．curiosity also helps us learn boring things
4．What do the underlined words “that problem”refer to?
A．Students get bored with learning.
B．Students ask too many foolish questions.
C．Students want to explore the mysteries of science.
D．Students take drugs to produce dopamine.
B
A poor set of curtains may not just mean you wake up too early—they could also make you fat.Sleeping in a room with too much light has been linked to an increased risk of piling on the pounds，a study shows.
Greater exposure to light at night raised both body mass index and waist size in more than 113,000 women taking part in the British study.The study followed the women for 40 years to identify root causes of breast cancer.Obesity is a known risk factor for the disease.
“The associations we saw in our study between light exposure at night and obesity are very interesting.We cannot yet tell at this stage what the reason for the associations is，but the results open up an interesting direction for research，”said Prof.Anthony Swerdlow，from the Institute of Cancer Research.“One possible explanation is that the light is interrupting the body clock，which stems from our evolutionary past(进化历程)．We were active when it was light in the day and restful when it was dark at night.”
Other research has found the effect of night-time lighting on the body may contribute to unhappy feelings.But it’s too early to suggest that sleeping in the dark will help prevent obesity，a known risk factor for breast cancer.The findings are reported in the American Journal of
Epidemiology.
Previous research has drawn similar conclusions.A team at Ohio State University examined how night-time light affects weight，body fat and glucose intolerance(葡萄糖过敏) in mice.They found that continuing exposure to even a little night-time light caused increases in all three aspects.
Light changes mood，physical strength and even the way we process food in a 24-hour cycle.Artificial light is known to interrupt the body clock by delaying the production of the sleep hormone melatonin(睡眠荷尔蒙褪黑激素)．So there is no harm in trying to make bedrooms darker.
5．What does the underlined part “piling on the pounds”in the first paragraph mean? A．Putting pounds into a pile.
B．Filling in with pounds.
C．Making a lot of money.
D．Gaining body weight.
6．From the passage，we know that .
A．sleeping in the dark must help prevent obesity
B．lighting on the body at night makes people happy
C．night-time light may affect human beings and mice
D．it is easy for women to become fat and have cancer
7．The most possible cause of the interruption of body clock is .
A．the sleep hormone melatonin
B．unhappy feelings
C．man-made light at night
D．glucose intolerance
8．The passage is mainly about .
A．evolutionary past of man
B．obesity and breast cancer
C．different research and conclusions
D．negative effects of night-time light

Safety in the highway is not totally out of our hands.Here are four ways we can protect ourselves when we travel.
10 People in small cars are injured more often and more severely than people traveling in large cars.Factories of small cars are strengthening their products’ safety，which helps.But the
mix of large cars and small cars on the road is the main reason of the problem.
Being thrown into glass and metal car parts，or being thrown from the car can really hurt or even kill you. 11 The safety belt’s main purpose is to pull you back if your car has a sudden crash with another vehicle or object，or if it rolls over.A belt can reduce the chance of deadly injury by 45% and the chance of serious injury by 50%.
Air bags are important.More than half of all new cars sold have air bags.Air bags provide protection in frontal crashes—the type of crash that kills the most drivers—when they are also wearing safety belts.Most people are demanding air bags in the cars they buy. 12 Effective as they are，they can’t take the place of safety belts.
Drunk driving crashes are less likely to happen if you don’t drink. 13 Many people have realized that drunk driving can lead to death and injury，prison time and other results.There are movements to strengthen penalties (处罚) for drinking and driving.
A．How to Drive Safely
B．You are safer in a large car.
C．How to Protect Ourselves in the Highway
D．Air bags are not installed in all cars.
E．That’s why safety belts should be worn.
F．Drunk driving is the most serious problem.
G．But the protection provided by air bags is limited in side or rear crashes.

阅读下列短文,从每题所给的四个选项中,选出最佳选项。 A To American visitors, Iceland is a very interesting country, partly because it is different in so many ways from what he or she is used to seeing at home. There are quite a few things that are not done, or that do not exist on the island —quite a few "No's". There is no pollution, for instance. No dogs are permitted in Reykjavik, the capital. There is no television on Thursdays or during the entire month of July, and only three hours of black-and-white TV the rest of the time. There is no hard liquor on Wednesdays and no beer at any time. There are no handguns; only one jail of thirty-five cells in the entire land —an admirable figure, even for a small country of 313,376 people. There is no army, air force or navy. There is no tipping for anything. There are no large stores open on Saturdays or Sundays. Since Iceland is situated just under the Arctic Circle, there is no darkness in summer and no daylight in winter. But thanks to Gulf Stream, the climate is rather mild, with temperatures ranging from 34 degrees Fahrenheit to 52 degrees in July. The rules on television, liquor, and guns are the result of governmental decision. But the absence of pollution is due in great part to the fact that Iceland gets its power from the enormous geyser(间歇泉and the thousands of hot springs that come out of the ground. They provide all the energy needed by the country. In fact, Iceland uses only 3 percent of all its available power. Iceland has been described as a democratic independent country where more fish are caught and more books published per person than anywhere else in the world. The Icelanders have always felt a particular love for literature. They composed their first works in the ninth and tenth centuries AD. These works were poems and tales about the kings, heroes, and heroines of Iceland and Norway. At first the stories were memorized

With today’s college application fees averaging around $ 80, you can expect to spend hundreds of dollars on college before you are even accepted into a school. One of the easiest ways to save money on college application fees before you begin applying is to narrow down your list of schools. To save money, try to limit the schools to which you apply to about 2- reach schools and 2- safety schools. At some schools, being a relative of a graduate can secure you a free application. If you are applying to a school where one of your parents or grandparents is a former graduate, check to see if you’re qualified for it. Research the preferred method of applying for each school on your list. Some schools offer free online applications, yet charge a fee for paper submissions. This is because online applications save schools the cost of employing a staff member to physically enter the application information. Several states, such as Michigan and North Carolina, take part in College Application Week, where many schools in the participating states cancel their application fee for the week. Be sure to contact the schools to I j which you are applying to see if they participate in College Application Week and when the program takes place in that state. Apply for early admission. If you have already decided on which college is your top choice, consider applying under an Early Action or Early Decision admission program. If you are accepted, you won’t have to submit application fees to other schools. For more information regarding college applications and the fees associated with them, contact your high I school advisor or the admissions department at your school(s) of interest. 21.The passage is mainly written to______. A.introduce famous universities in the United Stales B.show some practical ways to apply an ideal college C.advertise for successful applications and advisors D.offer tips to save money on college application fees

This trend, which was started by the medical community（医学界）61 a method of fighting heart disease, has had some unintended side 62(effect) such as overweight and heart disease—the very thing the medical community was trying to fight. Fat and salt are very important parts of a diet. They are required 63(process) the food that we eat, to recover from injury and for several other bodily functions. When fat and salt 64 (remove) from food, the food tastes as if it is missing something. As 65 result, people will eat more food to try to make up for that something missing. Even 66 (bad), the amount of fast food that people eat goes up. Fast food 67(be) full of fat and salt; by 68 (eat) more fast food people will get more salt and fat than they need in their diet. Having enough fat and salt in your meals will reduce the urge to snack(吃点心) between meals and will improve the taste of your food. However, be 69 (care) not to go to extremes. Like anything, it is possible to have too much of both, 70 is not good for the health. 翻译：最近，在食品服务业方面有一种朝着低脂肪和少盐的趋势。这种趋势最初是由医学界发起，用来作为防御心脏病的一种方式，已经产生一些意料之外的副作用，例如，肥胖 和心脏病，这正好是医学界致力去防御的疾病。 脂肪和盐分是每日膳食中的重要部分。我们需要他们去加工处理摄入的食物、有助于伤病的恢复和满足几项人体正常的运作。当脂肪和盐分从食物当中被去除了，食物尝起来 好像有所缺失。结果，人们会吃更多的食物来补偿缺失的东西。甚至更糟糕的是，人们吃 了更多的快餐食品。快餐中脂肪和盐的含量很高；由于吃了更多的快餐，人们会摄入比他 们在饮食中所需要的更多的盐分和脂肪。 通过每日饮食摄入足够的脂肪和盐分会减少在两餐之间吃点心的欲望，而且会提高你的食物的味道。然而，要注意不要摄入过量。跟其他食物一样，我们也有可能会吃太多， 这一点是对我们的健康不利。 61.as 考查介词。根据句意“这一趋势最开始被医学界作为一种治疗心脏病方法”可知这里 表达“作为”之意，所以答案填as。 62.effects 考查名词单复数。有前面的修饰短语some可知这里的side effects应该用复数，所以答案填effects。 63.to process 考查非谓语动词。根据固定短语be required to do sth.“被要求做某事”可知此处答案填to process。

2017届全国高考英语阅读理解汇编（1）英语试卷SYS201708100601 一、阅读理解 详细信息 1. 难度：中等 阅读理解。 Many of us still tend to think that emotions can affect reasonable thought，and sometimes land us in trouble. But in recent years psychologists have taken quite a different view. Keith Oatley，Professor of Psychology at Glasgow University，is involved in the research which shows the fundamental importance of emotions. He believes we are very ambivalent about them：we think of our emotions as being unreasonable，but we also consider them as essential to being human.For example，Mr Spock，a character in the television series Star Trek，is superintelligent and he has no emotions at all.However，he is never made captain of the spaceship.Maybe，this is because Mr Spock is not the kind of person you can share your feelings with—a person who shows his emotions. As Professor Oatley points out，our emotions have very important functions，for example，fear.If we cross the road and a car approaches，we usually stop moving or step back.We stop what we are doing，check what we have done and pay very careful attention to the environment.The emotion of fear makes us take this small series of actions which，on average，help preserve our safety. On the other hand，if things are going well and small problems come up，we find we can solve them with the resources we have to hand.As a consequence，we tend to feel happy and usually continue doing the job. Anger is an emotion that tends to occur when someone is preventing us from doing something.Then this small “kit” of reactions enables us to prepare ourselves to be quite aggressive to that person，or to try harder，and so on. Professor Oatley believes emotions generally occur at these important moments in actions.With fear and anger our emotions make us decide to start doing something else，while with happiness they “suggest” we continue what we are already doing. 1.What’s Keith Oatley’s opinion about emotions? A．They affect reasonable thought. B．They get us into trouble. C．They are helpful to us. D．They are reasonable. 2.What does the underlined part “we are very ambivalent about them”in Paragraph 2 mean? A．We have contradictory feelings towards emotions. B．We have similar ideas of emotions.

Only if you find a proper time to talk with your boss will you get a raise. D. You should schedule a meeting within a few months to discuss the matter again. B Here’s one number to keep in mind during your next cell phone conversation: 50. A new experiment shows that spending 50 minutes with an active phone pressed up to the ear increases activity in the brain. This brain activity probably doesn't make you smarter. When cell phones are on, they emit (发出) energy in the form of radiation that could be harmful, especially after years of cell phone usage. Scientists don't know yet whether cell phones are bad for the brain. Studies like this one are attempting to find it out. The 47 participants in the experiment may have looked a little strange. Each one had two Samsung cell phones attached to his or her head — one on each ear. The phone on the left ear was off. The phone on the right ear played a message for 50 minutes, but the participants couldn't hear it because the sound was off. With this set-up, the scientists could be sure they were studying brain activity from the phone itself, and not brain activity due to listening and talking during a conversation. After 50 minutes with two phones strapped to their heads, the participants were given PET scans. The PET scan showed that the left side (the side with the phone turned off) of each participant's brain hadn't changed during the experiment. The right side of the brain, however, had used more glucose, which is a type of sugar that provides fuel to brain cells. These right-side brain cells were using almost as much glucose as the brain uses when a person is talking. This suggests th at the brain cells there were active ― even without the person hearing anything. That activity, the scientists say, was probably caused by radiation from the phone. Henry Lai, who works at the University of Washington in Seattle, is uncomfortable with the data related to cell phones. Holding a cell phone to your ear during a conversation is “not really safe,” Lai told Science News. Lai is a bioengineer at the University of Washington in Seattle. He wrote an article about the new study for a journal, but he did not work on the study. Bioengineers bring together ideas from engineering and biology. For those who don't want to wait to find out for sure whether cell phones are bad for the brain, there are ways to talk more safely. You can have short and sweet conversations, use a
