The world itself is becoming much smaller by using modern traffic and modern communication means. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.
Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, man moved to another place. But this is no longer true.
Man is now slowly polluting the whole world.
Air pollution is still the most serious. It’s bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.
Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air. Pollution by SO2 is now the most dangerous kind of air pollution. It is caused by heavy traffic. We are sure that if there are fewer people driving, there will be less air pollution.
The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must take care of the rise in pollution at the same time.
1. _______, our world is becoming much smaller.
A. Because of the rise in pollution
B. Thanks to science development
C. Because the earth is being polluted day and night
D. Because the earth is blown away by the wind every year
2. Hundreds of years ago, life was __________ it is today.
A. much easier than
B. as easy as
C. much harder than
D. as hard as
3. Pollution comes in many ways. We can even hear it. Here “it” means _______.
A. rubbish(垃圾)
B. noise pollution
C. air pollution
D. water pollution
4. Air pollution is the most serious kind of pollution because _______.
A. it makes much noise
B. it makes us angry more easily
C. it makes our rivers and lakes dirty
D. it’s bad for all living things in the world
5. Which of the following is NOT true?
A. Many countries are making rules to fight pollution.
B. The pollution of the earth grows as fast as the world population does.
C. The problem of pollution is not so serious because there are not so many people living on the earth.
D. If people could go to work by bus or bike instead of car or motorbike, it would be helpful in fighting against the problem of SO2.
【答案与解析】本文谈到全球环境污染这个问题，同时号召人们来为我们的家园——地球出一份力，减少污染。
1. B。由文章的首句我们得知：世界变小是由于modern traffic and modern communication means(现在的交通运输工具和沟通工具的使用)，而这一切都要靠科学技术的发展，据此我们可以推出答案是B。
2. C。原文的第2句告诉我们Life today is much easier than it was hundreds of years ago(今天的生活比以前容易得多)，反过来说，以前的生活一定比今天的艰难，所以答案是C。
3. B。在众多选项中，只有选项B(noise pollution噪音污染)是听得见的。
4. D。我们根据第4段的第1, 2句Air pollution is still the most serious. It’s bad for all living things in the world…，可以得知空气污染之所以最为严重，正如选项D(它是危害全世界生物的)所说的那样。
5. C。选项C可以在原文第2段的第2句找到，但它缺少了前提条件many years ago(以前不严重而现在严重)，所以选项C是错误的。

The office has always been a place to get ahead. Unfortunately, It is also a place where a lot of natural resources start to fall behind. Take a look around next time you’re at work. See how many lights are left on when people leave. See how much paper is being wasted. How much electricity is being used to run computers that are left on. Look at how much water is being wasted in the rest-rooms. And how much solid waste is being thrown out in the rubbish cans. We bet it’s a lot.
Now, here are some simple ways you can produce less waste at work. When you are at the copier, only make the copies you need. Use both sides of the paper when writing something less important. Turn off your lights when you leave. Use a lower watt bulb in your lamp. Drink your coffee or tea out of your mugs instead of single-use cups. Set up a recycling box for cans and one for bottles. And when you’re in the bathroom brushing your teeth or washing your fac e, don’t let the tap run. Remember, if we use fewer resources today, we’ll save more for tomorrow.
1. The main purpose of the passage is to tell people _______.
A. the disadvantages of working in an office
B. the waste produced in an office
C. to save resources when working in an office
D. how to save water in a restroom
2. How many kinds of waste are mentioned in the passage？
A. Two.
B. Three.
C. Four.
D. Five.
3. From the passage we can infer that in the office ________.
A. using computers is a waste of resource
B. many people don’t turn off the computers after using them
C. computers are run by electricity
D. a computer is not a must for working
4. It is suggested that we use both sides of the paper at the copier because _______.
A. we are short of paper
B. the printing is not important
C. we should save paper
D. we have to pay for the paper
5. The underlined word mugs is most likely to be _______.
A. a machine that makes coffee
B. a container that can be used again and again
C. a paper product for tea
D. something that can only be found in an office
【答案解析】本文介绍了办公室资源浪费情况及节约办公资源的办法。
1. C。推断题。根据第2段的内容可知，文章是告诉人们怎样在办公的时候节约资源。
2. C。细节题。文章提到的资源浪费现象有：lights are left on; paper is being wasted; electricity is being used to run computers that are left on; water is being wasted in the rest-rooms; solid waste is being thrown out in the rubbish cans等。其中 lights are left on 和 electricity is being used to run computers that are left on 同属于浪费电，因此文章中一共提到4种资源浪费，即选 C。
3. B。细节题。根据 How much electricity is being used to run computers that are left on 可知答案为 B。
4. C。推断题。根据 Use both sides of the paper when writing something less important 可以判断，两面打印可以节约纸张，避免不必要的浪费。
5. B。词义猜测题。根据 Drink your coffee or tea out of your mugs instead of single-use cups.我们可以看出 mugs 和“single-use cups(一次性杯子)”相对，故可推测出 mugs 是“可反复使用的容器”。

一、高中英语阅读理解 1．阅读理解 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.

2020年高考英语阅读七选五专项训练八篇（一） （一） 6 Tips for Healthy, White Teeth ·Go on a white-teeth diet.If you're quaffing (畅饮) red wine and black tea, or smoking cigarettes, expect the results to show up as not-so-pearly whites. ·Throw away your toothbrush or electric toothbrush head every two to three months.__1__According to dentist Harold Katz, the best way to brush is by placing your toothbrush at a 45-degree angle against your gums (牙龈) and gently moving it in a circular motion.Grip the toothbrush like a pencil so you won't scrub (刷洗) too hard. ·Use a tongue scraper (刮刀) every morning to remove tongue plaque (舌斑) and freshen breath.One cause of bad breath is the build-up of bacteria on the tongue, which a daily tongue scraping will help banish (消除)．__2__ (清洁剂)” foods that are firm or crisp to help clean teeth as you munch (咀嚼)．__3__ ·Eat “detergent For best results, make “detergent” foods the final food you eat in your meal if you know you won't be able to brush your teeth after eating. ·Stay fresh.Check by licking (舔) your palm and smelling it while it's wet.If you smell something, it's time for a sugar-free breath mint (薄荷)．Shopping for mouthwash? __4__ Mouthwashes with too much alcohol can dry out mouth tissue, making it more prone (易于) to bacteria. ·Brushing your teeth first and last are the two most crucial times of the day, as saliva (唾液) which keeps plaque off teeth, dries up at night, so it's best to have all plaque cleaned off the teeth before sleep.__5__ A．Make sure it's alcohol free. B．Apples are good, as are raw carrots, celery and popcorn. C．Otherwise, you're just transferring bacteria to your mouth. D．However, the bacteria won't be staying on the top of your tongue. E．It's more effective than brushing your tongue with a toothbrush too. F．When you sleep without bacteria in your mouth, you will feel much better. G．It's also important to brush first in the morning to remove plaque and bacteria built up as you slept. 语篇解读：本文是一篇应用文。文章主要介绍了六条保持牙齿洁白、健康的建议。 可知，每隔两到三1．选C根据此空前“Throw away your toothbrush ...every two to three months.” 个月要换一次牙刷，本空应说明这样做的原因。C项(否则你就是在把细菌转移到嘴巴里。)符合语境。 2．选E根据空前的“One cause of bad breath ...which a daily tongue scraping will help banish (清 除)．”可知，刮舌板有助于有效清除舌头上堆积的细菌，故此处描述的是刮舌板的益处。E项意为“这 比用牙刷刷你的舌面更加有效”，符合上下文逻辑。其中it 指代“Use a tongue scraper every morning ...”
