There are three separate sources of danger in supplying energy by nuclear power.

First, the radioactive material must travel from its form of production to the power station. Although the power stations themselves are strongly built, the containers used for the transport of the materials are not. Normally, only two methods of transport are in use, namely road or rail. Unfortunately, both of these may have an effect on the general public, since they are sure to pass near, or even though, heavily populated areas.

Secondly, there is the problem of waste. All nuclear power stations produce waste that in most cases will remain radioactive for thousands of years. It is impossible to make these waste radioactive, and so they must be stored in one of the inconvenient ways that scientists have invented. For example, they may be buried under the ground, or dropped into deserted mines, or sunk in the sea. However, these methods do not solve the problem, since an earthquake could easily break the containers.

Third, there may occur the danger of a leak or an explosion at the power station. As with the other two dangers, this is not very likely, so it does not provide a serious objection to the nuclear program. However, it can happen.

Separately, these three types of dangers are not a great cause for worry. Taken together, though, the probability of disaster is extremely high.

1.Which of the following is FALSE ?

2.The author thinks that the ways to store nuclear wastes are ____________.

3.What do we learn from the last paragraph ?

4. What is this passage mainly about ?

There are three separate sources of danger in supplying energy by nuclear power．

First, the radioactive (有放射性的) material must travel from its place of production to the power station． Although the power stations themselves are strongly built, the containers used for the transport of the materials are not． Normally, only two methods of transport are in use, namely road or rail． Unfortunately, both of these may have an effect on the general public, since they are sure to pass near, or even through, heavily populated areas．

Second, there is the problem of waste． All nuclear power stations produce wastes that in most cases will remain radioactive for thousands of years． It is impossible to make these wastes non-radioactive, and so they must be stored in one of the inconvenient ways that scientists have invented． For example, they may be buried under the ground, or dropped into deserted mines, or sunk in the sea． However, these methods do not solve the problem, since an earthquake could easily break the containers．

Third, there may occur　 the danger of a leak (泄漏) or an explosion at the power station． As with the other two dangers, this is not very likely, so it does not provide a serious objection (不赞成，反对) to the nuclear program． However, it can happen．

Separately, these three types of dangers are not a great cause for worry． Taken together, though, the probability of disaster is extremely high．

The energy crisis (危机) has made people aware of how the careless use of the earth’s energy has brought the whole world to the edge of disaster. The over – development of motor transport, with its increase of more cars, more traveling, has contributed to the near – destruction of our cities and the pollution not only of local air but also of the earth’s atmosphere.

Our present situation is unlike natural disasters of the past. Worldwide energy use has brought us to a state where long – range planning is vital. What we need is not a continuation of our present serious state, which endangers the future of our country, our children, and our earth, but a movement forward in order to work rapidly and effectively on planetary problems.

This country has been falling back under the continuing exposures of loss of morality (道德) and the revelation (揭露) that lawbreaking has reached into the highest place in the land. There is a strong demand for morality to turn for the better and for some devotion that is vast enough and yet personal enough to enlist the devotion of all. In the past it has been only in a way in defense of their own country and their own benefits that people have been able to devote themselves wholeheartedly.

This is the first time that we have been asked to defend ourselves and what we hold dear in cooperation with all the other people of this planet, who share with us the same endangered air and the same endangered oceans. There is a common need to reassess our present course, to change that course and to employ new methods through which the world can survive. This is a priceless opportunity.

To grasp it, we need a widespread understanding of nature if the crisis we and the world are facing is no passing inconvenience, no by-product（副产品）of the ambitions of the oil – producing countries, no environmentalists’ only fears, no byproduct of any present system of government. What we face is the result of the invention of the last four hundred years. What we need is transformed life style. This new life style can flow directly from science and technology, but its acceptance depends on a sincere devotion to finding a higher quality of life for the world’s children and future generation.

1.Which of the following has nearly destroyed our cities?

A. The loss of beliefs and ideas.             B. More of law – breaking.

C. Natural disasters in many areas.           D.  The rapid growth of motors.

2.By comparing past problems with present ones, the author draws our attention to the ________.

A. seriousness of this crisis                 B. ineffectiveness of laws

C. similarity of the past to the present      D. hopelessness of the situation

3.Which of the following is used as an example to show the loss of morality?

A. Disregard for law.                       B. Lack of devotion.

C. Lack of understanding.                   D. Destruction of cities.

4.The author wrote the passage in order to ________.

A. make a recommendation for a transformed life style

B. limit ambitions of the people of the whole world

C. demand devotion to nature and future generation

D. encourage awareness of the decline of morality

We've used the wind as an energy source for a long time. The Babylonians and Chinese were using wind power to pump water for irrigating crops 4,000 years ago, and sailing boats were around long before that. Wind power was used in the Middle Ages, in Europe, to grind(磨碎) corn, which is where the term "windmill" comes from.

We can use the energy in the wind by building a tall tower, with a large propellor on the top. The wind blows the propellor round, which turns a generator to produce electricity. We tend to build many of these towers together, to make a "wind farm" and produce more electricity. The more towers, the more wind, and the larger the propellors, the more electricity we can make. It's only worth building wind farms in places that have strong, steady winds, although boats and caravans（大篷车）increasingly have small wind generators to help keep their batteries charged.

The best places for wind farms are in coastal areas, at the tops of rounded hills, open plains and gaps in mountains—places where the wind is strong and reliable. Some are offshore. To be worthwhile, you need an average wind speed of around 25 km/h. Most wind farms in the UK are in Cornwall or Wales. Isolated places such as farms may have their own wind generators. In California, several “wind farms” supply electricity to homes around Los Angeles.

The propellors are large, to obtain energy from the largest possible volume of air. The blades can be angled to cope with varying wind speeds. Some designs use vertical turbines(垂直涡轮机), which don't need to be turned to face the wind. The towers are tall, to get the propellors as high as possible, up to where the wind is stronger. This means that the land beneath can still be used for farming.

1. The first paragraph aims to introduce to us _______.

A. the function of wind power             B. the source of wind power

2.How does a wind power work?

A. The generator turns the propellor blades and produce electricity.

B. The tall tower helps turn the energy in the air into electricity.

C. Warm air rises and makes the propellor move round.

D. The propellor blown round by wind turns the generator to produce electricity.

3. The best places for building the wind farm are places where _______.

A. boats and caravans can often be seen       B. isolated farms don’t have enough electricity
