If it looks like a fish and swims like a fish, it usually is a fish. But not the new, lifelike robot fish developed by UK scientists, which have been swimming around the London Aquarium(水族馆) as they wait for their release off northern Spain in 2011.

Equipped with tiny chemical sensors(传感器),the fish will collect data on pollution in the port of Gijón and wirelessly send the information back to the control center.

“It’s a little lab onboard the fish,” said Rory Doyle, a scientist at BMT Group. The robots were designed, and are being built, by professor Huosheng Hu and his team at the University of Essex, UK.

The fish, therefore, will be built “robust” enough to handle any possibilities, Doyle said. They can’t get caught in nets easily, for instance, and the tracking systems inside can help the robot fish avoid crashes with boats and other things in the way.

One way of preventing floods may be by making rain. This may sound rather strange. As we know, heavy rain is the cause of floods, and in Malaysia most of the floods are caused by the annual monsoon(季风), which brings heavy rain to the east coast. If, however, the rain could be made to fall in the China Sea, there would be no more follds since the rain clouds would not reach the east coast.

Is it possible to make clouds give up their rain? Yes, it is, and in 1973 the National Institute of Scientific and Industrial Research (NISIR) suggested that it would be tried. The institute knew of course that it was not possible to make all clouds give up all their rain. It calculated (估计，计算), however, that if the frequency （频率） of rainfall could be reduced by 10%, and the amount of rain that fell each time could be reduced by 15%, the total amount of flood damage would be reduced by 40%--50%.

As you probably know, clouds are caused by air containing water-vapor. The air rises and, since water-vapor becomes water when it cools, very tiny drops of water are formed. Since these drops are very small, they float in the air, and form a cloud. When the cloud rises, however, the drops become colder. Because of this, they join together and become big drops. The big drops are no longer able to float because of their weight, and they fall. As they fall, they pick up more drops and become bigger. This is the cause of rain.

1. According to the passage, one way of preventing flood is ____________.

　 A. to bring heavy rain　　　　　　　　　

B. to make the rain clouds

C. to cause monsoon in the sea　　　　　

D. to make the rain fall in the sea before it reaches the coast

2. Which of the following statements is NOT true?

　 A. In Malaysia, the monsoon often results in floods.

B. It is likely to cause all clouds to give up all their rain.

C. The frequency of rainfall could be cut down, and so could the amount of rainfall.

D.If people found ways of reducing the amount of rainfall, there would be less flood damage.

3. What does “it” of “since water-vapor becomes water when it cools” (in Para.3) refer to?

　 A. Cloud　　 B. Water　　 C. Water-vapor　　 D. Air

4. The third paragraph is about ___________.

A. how clouds cause rain　　 B. how rain is formed

C. how clouds rise the air　　 D. why water-vapor can float in the air

5. It can be inferred from this passage that ___________.

　 A. the higher the air rises, the higher the temperature is

B. the clouds rise, and the water drops become smaller

C. the higher the air rises, the lower the temperature gets

D. the rain is caused by water-vapor

完形填空

　　One way of preventing (阻止) floods may be by making rain! This may sound rather 1 . As we know, heavy rain is the 2 of floods, and in Malaysia, most of the 3 are caused by the annual monsoon (一年一度的湿季风), which brings heavy rain to the east coast. If, 4 , the rain could be made 5 in the South China Sea, there would be 6 floods since the rain could not reach the east coast.

　　Is it possible to make 7 give up their rain? Yes, it is.

　　As you probably know, clouds are caused 8 air containing water-vapor (水蒸气). The air rises and, since water-vapor 9 water when it cools, very tiny drops of water are formed. Since these drops are very 10 , they float (漂浮) in the air and 11 a cloud. When the cloud rises, however, the drops become 12 . Because of this, they 13 together and become big drops. The big drops are no longer able to float because of their 14 , and they fall. As they 15 , they pick up more drops and become bigger. This is the cause of rain.

　　Rain making 16 making these bigger drops form and fall 17 they would normally do so. This can be done by “seeding” the clouds with chemicals, 18 planting seeds in the ground. Rain can be produced 19 by these chemicals. The seeding is done by 20 which fly through the clouds.
