There is very simple way of measuring the height of a water-tower, which we cannot measure by climbing.

Suppose, for example, that we wish to find out the height of the water-tower, AB, in a factory. We first of all go to where the water-tower is standing and measure a distance of, say, 25 feet from it. Then we take a stick, and stand it in the ground at the spot we have just marked.

Let us suppose the stick we are using is 4 feet in height. We now walk farther away from the water –tower in the same straight line as when we measured off the distance of 25 feet. We go from the water-tower until we come to point E, where with our head on the ground, we see the top of the stick and the top of the water-tower in the same height line---that is, the top of the stick just covers the highest part of the water-tower. Every schoolboy can work out the height of the water-tower now.

Suppose that the line CE is five feet. We know that the stick is 4 feet high and the distance BE is 30 feet. Thus, 5 is to 4 as 30 is to AB.

1.If we want to know how high a tall tree is,_______.

A. we have to climb up the tree

B. we have no way out

C. we must cut down the tree

D we needn’t climb up the tree

2. According to the passage, which of the following is correct?

3.It is clear from this that the problem can be settled by _________.

A. a child

B. the boy who has little schooling

C. everyone

D. a girl at middle school

4.To measure a water-tower in this way, _________.

A. no tool is needed

B. Besides a stick, tape-measure (卷尺) or at least a ruler is necessary.

We all need physical exercise. Exercise uses up food we eat and keeps the body full of energy. It works our muscles and makes our heart work hard so as to send blood to our muscles. So, exercise makes our heart and muscles strong. Exercise also makes us feel refreshed. If you exercise a couple of times a week, you will stay happy and healthy.

Some Western countries, such as the United States, have problems with exercise. In the US, many people don’t have enough exercise because it is hard for them. People have to work from dawn till dusk, so they don’t have time to take exercise. They work in office buildings sitting in chairs all day long in front of computers. They cannot get much exercise sitting at desk passively.

Some Westerners can get exercise walking from their homes to work. However, the majority of the people cannot do this. It is too far from their homes to their offices. They have no choice but to drive to work. In fact, some have to drive one or two hours to their offices. This has an unfavourable effect on them in two ways. First, these people don’t have a chance to exercise because they are sitting in their cars for two to four hours each day. Second, driving is challenging especially in rush hours and calls for too much attention. It makes a person worn out. So, when these people arrive home at night, they don’t have the desire to take exercise after work.

Today, many people in the West are overweight, which causes health problems for them. Doctors say exercise can help people both lose weight and improve their health. So many people are trying to get more exercise. But it takes time to change, and when people don’t see a difference right away, they will lose heart and stop exercising.

1.List two of the benefits we can get from physical exercise. (No more than 15 words)

2.Why can’t people in the US take enough exercise? (No more than 10 words)

3.The underlined word in paragraph 3 probably means __________. (1 word)

Water and its importance to human life are the center of the world’s attention. March 22 is World Water Day, which has the theme “Water and culture ”this year. Ther are more than one billion people in the world who live without safe drinking water. The United Nations hopes to cut this number in half by 2015.

Solving such a big problem seems like an unreal challenge. But everyone, even teenagers, can do something to help. A teenage girl in the U.S. has set an example to others of her age around the world. Rene Haggerty, 13, was awarded the 2004 Gloria Barron Prize for her work of collecting deserted batteries which pollute water.

In 2003, Haggerty went on a field trip to the Great Lakes Science Centre in Ohio. There, she saw an exhibit about how chemicals in old batteries harm the water of Lake Erie. Haggerty learnt that recycling the batteries was an easy solution. “I think everybody can do it, because everyone uses batteries, and it can make a big difference.”With these words, she began to increase awareness in her area.

She talked to her county government and school board. She got permission to start a recycling programme in schools as well as the public libraries, hospitals, and churches. With the help from her family, friends and local waste-management officials, she gathered containers, arranged transportation, and made an educational video.

Over the past two years, she collected four tons of batteries and drew the attention of officials, who were in charge of a battery recycling programme but had made little progress. When asked if she feels like a hero, Haggerty is quite modest. “Not really. Well, maybe for the fish I saved!”

Every year the Gloria Barron Prize honors young Americans aged 8 to 18 who have shown leadership and courage in serving the public and the planet. Each year ten winners receive ＄2,000 each, to help with their education costs or their public service work.

1.According to the passage, how many people probably can’t drink safe drinking water in 2015?

A.About I billion.                           B.About 2 billion.

C.About 500 million.                     D.About 5 million.

2.In order to collect used batteries, Rene Haggerty did the following things EXCEPT________.

A.gather some containers                 B.arrange the transportation

C.make an educational video             D.go on a field trip

3.The best title for this passage should be ________.

A.A girl awarded the 2004 Gloria Barron Prize

B.A girl acts to clean the world’s water

C.We should protect our environment

D.A girl collecting batteries

Bend over, take a deep breath and drink some water! This is just one of the hundreds of tips you might get if you have the hiccups(打嗝). Hiccups are so mysterious. We really don’t know why they start and why they stop.

Everyone has a favorite cure for a case of the hiccups. Some people think that a good scare is necessary to get well. Others eat a teaspoon of sugar. Still others drink a glass of water with a knife in it.

An American man named Jack O’Leary claimed to have hiccupped 160 million times over a period of eight years. He tried 60,000 cures, but none of them worked. Finally he prayed to Saint Jude, the saint of Hopeless cases, and his hiccupping stopped immediately.

It took a British plumber eight months to cure his hiccups. People from all over the world wrote him letters with suggestions for getting well. He tried them all, but the hiccups continued. Finally, he drank a “secret’’mixture someone had sent him. By that evening his hiccups were gone. Why did these cures work for these two men? No one really knows. But people who have studied many cases of hiccups have an idea. Hiccups usually go away if you believe in the cure.

1.

________might be the best cure for hiccups.

2.

The plumber spent________in stopping his hiccups.

3.

According to the passage, which of the following is TRUE?

4.

What is the main idea of this passage?

高二英语阅读理解简单题查看答案及解析

We all know that water is tasteless. But it happens from time to time: you pick up the bottle of water you didn’t finish yesterday, and it tastes strange. Most often, you tend to drop the bottle in the trash bin, believing that the water has gone bad. But is it true?

According to Time, of course not, taste has little to do with quality of water.

According to Time, when water is exposed to the air for 12 hours, carbon dioxide interacts with the H2O in the water, and the pH value lowers slightly. As a result, the water has a different taste.

“But it’s most likely safe to drink,” Norwegian expert Truls Krogh told Science Nordic. “If the water is covered and of good quality to start with, in principle it can last a thousand years. That’s because when water is fresh, it contains little organic matter. As long as water is held in clean glasses or bottles, no pollutants will enter it to harm our health.”

People in countries like the US, the UK and Australia usually drink tap water. According to Time, if tap water is drunk within six months, the chlorine (氯气) in the water will be enough to kill any bacteria and keep it safe to drink.

However, there are also some exceptions. If you accidentally put your fingers into water or store water in unclean containers day after day, microorganism (微生物) will enter the water.

With the help of surrounding temperature, and sunlight streaming through windows, these microorganisms multiply quickly. Sooner or later, the water will be in the charge of the unfriendly bacteria. And if you drink the water too often, then you’re more likely to be ill.

And what about water in plastic bottles? Heat and plastic are a bad combination, US researcher Kellogg Schwab stresses. When plastic bottles are used at high temperatures, they produce a chemical called BPA. BPA is something that affects hormones (荷尔蒙) and research has tentatively linked it to “several health damage, including heart disease and cancer”, Time reported.

Schwab suggests replacing disposable (一次性的) plastic bottles with the refillable containers made of metal or glass to deal with BPA.

1.The purpose of the first paragraph is to ________________.

A. show an example B. draw a conclusion

C. analyze a phenomenon D. introduce a topic

2.Which of the following may Truls Krogh agree?

A. If the water tastes different, we shouldn’t drink it.

B. The water held in a clean container is likely safe to drink.

C. Although kept fresh, water may still have much organic matter.

D. Covered water can last for a thousand years.

3.What can we infer from the passage?

A. BPA does little harm to our health.

B. Tap water is always safe to drink.

C. Microorganisms are easy to produce in the heat.

D. Disposable plastic bottles have been banned already.

4.What can be the best title of the passage?

A. Why Water is Tasteless B. How to Get Clean Water

C. Does Water Really Go Bad? D. Learn to Protect Water
