Now more water is needed. The problem is: Can we avoid (避免) a serious water shortage later on? First, we should all learn how to save water. Secondly, we should find out the ways to reuse it . Scientists have always been making studies in the field. Today, in most large cities water is used only once and then runs to the sea or rivers . But it can be used again. Even if every large city reused its water, still there would not be enough. What could people turn to next?
The sea seems to have the best answer. There is a lot of water in the sea. All that needs to be done is to get the salt out of the sea water. This is expensive, but it"s already used in many parts of the world. Scientists are trying to find a cheaper way of doing it. So you see, if we can find a way out, we"ll be in no danger of drying up.
小题1:The world is thirsty because ________.
A.3/4 of the earth is covered with water |
B.we have enough sea water to use directly |
C.we haven"t used all the water in rivers and lakes |
D.about 97% of water on the earth can"t be drunk or used for watering plants directly |

B.75% of water on the earth is the sea. |
C.97% of the earth is covered with water. |
D.3% of water on the earth is sea water. |
A.if every city reuses its water, we"ll be in no danger of drying up |
B.man can only drink and use about 25% of water on the earth |
C.today in most large cities water is used only once |
D.water can be used only once |
A.Save water and try to make good use of the water in rivers and lakes. |
B.Don"t pollute water and keep all rivers and lakes clean. |
C.Make dirty water clean and then reuse it. |
D.Try to find a cheaper way to get the salt out of the sea water. |
A.The Sea Water | B.How to Save Water |
C.The Thirsty World | D.The Polluted Water |
答案
小题1:D
小题2:A
小题3:C
小题4:D
小题5:C
解析
试题分析:地球不仅是饥饿的还是干渴的,因为我们只能使用全球水分的3%。为了避免缺水,我们首先要节约用水,其次是要找到再利用水的方法。最好的答案是从海水中分离出盐,但是这个方法成本很高。科学家们还在不断努力以找到经济有效的办法。
小题1:细节理解题。短文第一段提出了问题,也给出了答案Because about 97% of water on the earth is sea water which we can"t drink or use for watering plants directly.“因为地球上97%的水是海水,我们不能直接饮用或用它们来浇灌植物。”所以答案是D。
小题2:推理判断题。短文说到:Man can only drink and use the 3% - the water that comes from rivers and lakes“人们只能饮用和利用其中的3%,这3%的水来自河流和湖泊”。因此河流和湖泊的水只占全球水的3%,故选A。
小题3:细节理解题。Today, in most large cities water is used only once and then runs to the sea or rivers .“今天,在大多数大城市水只是利用过一次就流入大海和河流”。由此可知,答案是C。
小题4:细节理解题。短文最后一段说最好的答案就是海洋,就是从海水中提出盐,但是很贵,科学家们在寻找廉价的办法从海水中提出盐。所以,找到便宜的办法才是最重要的。故选D。
小题5:细节理解题。短文先介绍了地球的水资源很有限,接着讲了避免水缺乏的方法。所以文章的主题中心词就是thirsty,故选C。

A good memory is a great help in learning a language. Everybody learns his mother language when he is a small child. He hears the sounds, remembers them and then he learns to speak. Some children are living with their parents in foreign countries. They can learn two languages as easily as one because they hear, remember and speak two languages every day. In school it is not so easy to learn a foreign language because the pupils have so little time for it, and they are busy with other subjects, too.
But your memory will become better and better when you do more and more exercises.

London has a population of about 7, 000, 000. From about the year 1800 to 1945, London was the biggest city in the world. But now many cities are even bigger than before.
London is famous for many things. Tourists come from all over the world to visit its famous buildings and listen to the famous clock, Big Ben.
Like many big cities, London has problems such as traffic and pollution, and they stop the city from developing. Every day about 1, 000, 000 people come and go by underground, but there are still too many cars and buses in the streets. So the air isn’t clean. However, it is cleaner than it was 100 years ago.
For me, the best things in London are the parks. There are five parks in the city centre. But my children’s favourite place is Hamleys, the biggest toy shop in the world.

A.toy shop | B.museum | C.park | D.clock |
A.London has a population of about 7, 000, 000 |
B.London is famous for buildings and Big Ben |

The honey guide does not actually like honey, but it does like the wax(蜡) in the beehives (蜂房). The little bird cannot reach this wax, which is deep inside the bees" nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them tot he nest. When they finally arrive at the nest, the follower reaches in to get the delicious honey as the bird patiently waits and watches. Some of the honey, and the wax, always fall to the ground, and this is when the honey guide takes its share.
Scientists do not know why the honey guide likes eating the wax, but it is very determined (下决心) in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper(养蜂者) is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.
