Water problems in the future will become more...

Water problems in the future will become more intense and more complex. Our increasing population will tremendously increase urban wastes, primarily sewage. On the other hand, increasing demands for water will decrease substantially the amount of water available for diluting wastes. Rapidly expanding industries which involve more and more complex chemical processes will produce larger volumes of liquid wastes, and many of these will contain chemicals which are noxious. To feed our rapidly expanding population, agriculture will have to be intensified. This will involve ever - increasing quantities of agricultural chemicals. From this, it is apparent that drastic steps must be taken immediately to develop corrective measures for the pollution problem.

There are two ways by which this pollution problem can be dwindled(减少). The first relates to the treatment of wastes to decrease their pollution hazard . This involves the processing of solid wastes "prior to" disposal and the treatment of liquid wastes, or effluents, to permit the reuse of the water or minimize pollution upon final disposal .

A second approach is to develop an economic use for all or a part of the wastes. Farm manure is spread in fields as a nutrient or organic supplement. Effluents from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained. Effluents from other processing plants may also be used as a supplemental source of water. Many industries, such as meat and poultry processing plants, are currently converting former waste products into marketable byproducts. Other industries are potential economic uses for waste products.

1.The purpose of this passage is ________.

A．to alert the reader to the dwindling water supply

B．to explain industrial uses of water

C．to acquaint the reader with water pollution problems

D．to demonstrate various measures to solve the pollution problem

2.Which of the following points is NOT included in the passage?

A．Industrial development includes the simplification of complex chemical processes.

B．Diluting wastes needs certain amount of water.

C．Demands for water will go up along with the expanding population .

D．Intensive cultivation of land require more and more chemicals.

3.The reader can conclude that _________.

A．countries of the world will work together on pollution problems

B．byproducts from wastes lead to a more prosperous marketplace

C．science is making great progress in increasing water supplies

D．some industries are now making economic use of wastes

4.The author gives substance to the passage through the use of________.

A．interviews with authorities in the field of water controls

B．opinions and personal observations

C．definitions which clarify important terms

D．strong arguments and persuasions

5.The underlined words "prior to"(para. 2)probably man________.

Next autumn, studying for a degree in Britain will become more expensive, and the results are already clear. This week, figures from UCAS(the Universities and College Admissions service)show a 15-percent downturn in applications(申请) from this time last year. With fees having reached ￡9,000 a year, some students are beginning to consider other ways of getting higher education—including distance learning, which allows them to get a degree while still living, and earning money, at home.

That is important, because fees are only part of the picture. The National Union of Students says that UK students pay an average of ￡4,900 a year for basics such as rent, food, books, equipment, field trips and the like. If those costs can be reduced, the burden of fees will be lessened. Therefore, many people are thinking not only about what and where to study, but how—that is, whether they have to be on campus to get a degree.

Distance learning is best suited to certain subjects and to ultra-motivated(极有主动性的)student, according to Carrie-Anne Rice of Resource Development International(RDI).“The advantage is that the fee system is more flexible(灵活的), and you can have full-time work while studying, Rice says.”“You graduate three years ahead of possible competitors(竞争对手)— with the same degree, but with three years of work experience and without the debt.”

“I left school and went straight into work. But at the age of 23, I changed career and soon realized I needed a degree to advance. Because of lack of money ad time, full-time university wasn’t a good choice, but I discovered that distance learning was financially flexible and enabled me to work and gain skills from my workplace without affecting the quality of my life,” Andy Cain, a distance learning student says.

Although distance learning has many advantages, a campus-based university experience remains the dream of most school-leavers. There is no question that “being there” is not only fun, but rich in shared experience, pooled knowledge, and—perhaps most importantly—friendships that will go on long after the degrees have been awarded.

1.The number of students applying to universities________compared to this time last year.

A．has increased greatly                    B．has decreased

C．hasn’t shown any change                D．has become zero

2.Students who study on campus spend________each year, on average.

A．￡9,000          B．￡4,900           C．￡13,900          D．￡4,100

3.Which of the following is NOT the benefit of distance learning?

A．Lower debt levels                       B．A head start on the job market.

C．Valuable friendships                     D．A flexible fee system.

4.Which of the following statements is TRUE?

A．The change in fees has had no effect on school-leavers.

B．Distance learning has the same advantages as campus-based learning.

C．Distance learning is so attractive that nobody wants to go to university any more.

D．Distance learning doesn’t suit all subjects or all students.

Controlling traffic is a complex and high cost problem in many developed countries. It becomes more difficult and costly with the ever-increasing number of cars on the roads. But scientists and students at the CATT, at the University of Maryland are working to solve this problem. They are using simulation(模拟) technologies to help government and private business control and react to 　　 changing traffic conditions.

The online economics magazine Forbes.com says traffic congestion(拥挤) cost Americans $ 124 billion in 2014 and that number could rise to $ 186 billion by 2030.

But scientists at the CATT lab are trying to reduce those costs. They are developing a system that helps traffic managers, planners, emergency workers and businesses plan and react better. Michael Pack is CATT director. He says the system is important to help emergency workers, or first responders. reach an accident area faster.

The CATT Lab collects information from many sources, including roadside devices, GPS (global positioning system) equipment and wireless phones.

About 60 students and 30 software developers observe traffic flow and manage the computer servers at all times. They also work to develop software and applications that can help traffic run smoother and safer, Some of them turn the information gathered into so-called "visualizations". These visual representations help emergency workers better understand what is happening.

The center shares its findings with firefighters, police. Transportation departments and the military. They also share information with universities and transportation company.The technology company Google uses the data for its traffic-related websites. Michael Pack says, the information is then shared with anyone who wants to help traffic run more smoothly.

Mr. Pack says the goal is to help develop an intelligent system of road signals that will communicate with each other and with vehicles on the road.

1.The second paragraph is written to

A. attract more people to look through Forbes.com.

Environmental problems are becoming more and more serious all over the world. For example, cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories. Trees on the hills have been cut down and waste water is being poured continuously into rivers. Furthermore, wherever we go today, we can find rubbish carelessly disposed.

There are different kinds of pollutants, each of which comes from different sources. It is necessary to identify the source of pollution, in order to make a policy to eliminate them.

Different products, processes and activities of our industrialized world together form the major source of pollution. The forms of pollution can be mainly divided into three kinds—solid, liquid and gas.

These pollutions have greatly damaged our planet and continue to do so. In fact, pollution is threatening our existence. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even posed a great threat to man’s existence.

We must face the situation that exists and take action to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the public must receive the education about the danger of pollution and so on.

The earth is our home and we have the duty to take care of it for ourselves and our later generation. Fortunately, more and more people have realized these problems. Measures have been taken to deal with these situations by the government. Laws have been passed to stop pollution, I hope the problems will be solved in the near future and our home will become better and better.

1. How many examples of environmental problems are given in the first paragraph?

A. 2                             B. 3                    C. 4                              D. 5

2. Which of the following is TRUE according to the passage?

A. In all there are three kinds of pollution

B. If people continue to pollute our planet, there will be no trees.

C. Industrial pollution has been completely controlled.

D. Laws have been passed to stop pollution and protect our environment.

3. The sentence “We hope that all these measures will be effective and bring back a healthy environment” can best be put at the end of paragraph _____.

In the future your automobile will run on water instead of gas! You will be able to buy a supercomputer that fits in your pocket! You might even drive a flying car!

For each prediction that has come true today, several others have missed by a mile. Many of these predictions didn’t consider how people would want to use the technology, or whether people really needed it in their lives or not. Let’s look at some predictions from the not-too-distant past.

Robot Helpers

Where’s the robot in my kitchen? Nowhere, of course. And he’s probably not coming anytime soon. Robots do exist today, but mostly in factories and other manufacturing environments.

Back in the 1950s, however, people said that by now personal robots would be in most people’s homes.

So why hasn’t it happened? Probably because robots are still too expensive and clumsy. And maybe the idea of robots cooking our dinners and washing our clothes is just too weird. At home we seem to be doing fine without them.

Telephones of Tomorrow

In 1964 an American company introduced the video telephone. They said by the year 2000 most people would have a video phone in their homes. But of course the idea hasn’t caught on yet.

Why? The technology worked fine, but it over-looked something obvious: people’s desire for privacy. Would you want to have a video phone conversation with someone after you just step out of the shower? Probably not—it could be embarrassing! Just because a technology available doesn’t always mean people will want to use it.

And finally, how about that crazy prediction of the flying car? It’s not so crazy anymore! But a flying car remains one of the most fascinating technology ideas to capture our imagination. Keep watching the news, or perhaps the sky outside your window, to see what the future will bring.

1.The whole passage is mainly about　　.

A. predictions that have come true

B. predictions that haven’t come true

C. why predictions don’t come true easily

D. what technology will bring about

2. The author of this passage won’t believe that　　.

A. predictions needn’t consider people’s practical use of technology

B. the future isn’t always easy to guess

C. not all past predictions have come true

D. many of the high-tech things our parents thought we’d be using by now simply never appeared

3.The underlined word “weird” in Para. 5 probably means　　.

A. wonderful　　　　　　        B. stupid

C. practical                            D. strange

4.What does the author think of the flying car?

A. It is too difficult to imagine.

B. It is too crazy an idea.

C. It is likely to be made.

D. It is often reported in the news.

Not all past predictions have been proved wrong. A few of them have been surprisingly accurate (正确无误). Some great thinkers predicted the arrival of the credit card, the fax machine and even the internet years before they happened. But for each prediction that has come true, some others have missed by a mile. Many of these predictions didn’t consider how people would want to use the technology or if people really needed it in their lives or not. Let’s look at some predictions from the not-too-distant past.

1.The passage mainly deals with______.

A. predictions that can catch our imagination

B. predictions that haven’t come true

C. new technology can benefit our life

D. predictions that have come true

2.According to the passage, which of the following statements is NOT true?

B. Predictions don’t need to consider people’s practical use of the technology.

C. Not all the high-tech things people thought we’d be using by now are widely used.

D. High-tech things are not always convenient to people’s life.

3.Robot Helpers haven’t been used in most people’s homes because ______.

A. using the kind of robots at home is simply a waste of time and money

B. the kind of robots hasn’t been developed yet

C. people find it difficult to control the kind of robots

D. the kind of robots won’t bring people practical use

高三英语阅读理解中等难度题查看答案及解析

What's going to happen in the future? Will robots take over our planet? Will computers become smarter than us? Not likely. But here are some things that scientists say are most likely to happen 10 to 30 years later from now, according to the BBC.

1．Digital money

We used to pay with cash for everything we bought. Now when we swipe(刷) our bus pass or use a credit card to shop online, money is spent without us even seeing it. In fact, we are already using one type of digital money.

You have to admit that using a card is much easier than searching your pockets for change. It is also safer than carrying a lot of cash.

When ATM cards were first introduced, they were not accepted everywhere. But now it's hard to live without them. People in Sweden completely stopped using cash last year, according to the Associated Press, and the US might be next.

2．Bionic(能力超人的)eye

It's no longer something only in a sci­fi movie. People who are blind may have a chance to get their sight back—by wearing bionic eyes.

A blind eye can no longer sense light, but a bionic eye can use a camera to “see” the environment and send data directly to the brain.

Although the bionic eye that's out now only allows patients to see lights and unclear shapes, a high­resolution(高清晰度的) version could be just a few years away.

3．Self­driving cars

Everything is going automatic these days—washing machines, ticket selling machines and even cars. Unlike a human driver, a self­driving car won't get distracted by a phone call, the radio or something outside the window. Sensors and cameras on the car would allow it to stick strictly to the rules of the road and keep a safe distance from other cars. This would greatly reduce the number of road accidents. You could even take a nap while the car drives itself.

Many vehicle companies are now planning self­driving cars. “By 2040, driverless vehicles will be widely accepted and possibly be the dominant vehicles on the road，” said Jeffrey Miller, professor at the University of Alaska Anchorage, US, in Wired magazine.

1.The underlined word “distracted” in the article is closest in meaning to “________”．

A．directed　     B．discouraged

C．attacked　     D．disturbed

2.Jeffrey Miller's attitude towards self­driving cars is ________.

A．optimistic　     B．pessimistic

C．doubtful　     D．cautious

3.Which section is the article most likely to be found in the newspaper?

A．Learning Kit　     B．Campus Trends

C．Entertainment　     D．Technology
