5.Scientists will put some robot fish into the sea near Spain this year.These robot fish will help people find out the pollution in the water.If the robot fish are able to finish their work successfully,the team of scientists hopes the fish will be used in rivers,lakes and seas around the world.
The robot fish are about 1.5meters long.There is a detector(探测器) in their bodies.It can find the pollution in the water,and then the robot fish will eat part of it.
They can"swim"for eight hours in the sea freely and send back information to people on the beach.After their energy(能量) runs down,they will go back to the beach by themselves.
There are five robot fish altogether.Each costs about 29,000dollars.They are part of a three-year project between engineering company(公司) BMT Group and Essex University in southeastern England.

分析 今年科学家们将把一些机器鱼放在西班牙附近海域.这些机器鱼将帮助人们在水中找到污染.如果机器鱼能够成功地完成他们的工作,科学家们希望鱼将被用在世界各地的河流,湖泊和海洋.
解答 61.C 细节理解题.第一段第二句These robot fish will help people find out the pollution in the water.可知这些机器鱼将帮助人们在水中找到污染.所以该选C.
62.A 细节理解题.第二段第三句It can find the pollution in the water,and then the robot fish will eat part of it.可知它能在水里发现污染,然后机器鱼会吃掉它的一部分.所以该选A.
63.B 细节理解题.三段第二句The robots all have an eight-hour battery (电池).可知机器鱼体内的电池可以使用八小时,所以该选B.
64.C 细节理解题.第四段前两句There are five robot fish altogether (总共).Each costs (花费) about 29,000 dollars.可知每个机器鱼成本约29000美元,五个共计145,000美元,所以该选C.
65.D 细节理解题.第三段最后一句After their batteries run down,they will go back to the beach by themselves.可知电池耗尽后,机器鱼就自己去海滩.所以该选D.
