2．Each year，thousands of dolphins are caught in fishing nets around the world．Now，biologists in Canada are trying to find to find a way to make dolphins safe．
Biologists in Canada are trying to find out how to prevent dolphins from being caught in fishing nets．They say their study aims is to discover whether dolphins can perceive （察覺）fishing nets and why they swim into them．Some dolphins in Canada are being trained to swim with their eyes covered．
They process takes a long time，as dolphins are uncomfortable at first with foreign objects in their own bodies．By working slowly and rewarding the dolphins with fish，the animals grow comfortable in swimming with their eyes covered at last．
Every dolphin is a little bit different．Some dolphins are every comfortable having them on their bodies．Some dolphins were a little uncomfortable having them on their bodies and will try to swim away or try and take them off．But I think all of the dolphins with their eyes covered can listen to sound cues （暗號） that help them find their way around by using passive listening．
The scientists want to discover how dolphins choose to use echolocation （同聲定位法），or passive listening．
Further experiments will have the dolphins swim through an obstacle （障礙物） field of good objects that won't hurt the animals，such as nets，ropes in the water．

分析 有很多海豚被漁網網住，加拿大的科學家想要保護海豚，通過訓練和研究找到海豚是否能否感應到漁網，為什么會鉆進漁網，從而去保護海豚．
解答 BABAD
61．B．細節(jié)題，結合thousands of dolphins are caught in fishing nets around the world．Now，biologists in Canada are trying to find to find a way to make dolphins safe是因為很多海豚被漁網網住，故選B．
62．A．細節(jié)題，結合They say their study aims is to discover whether dolphins can perceive （察覺）fishing nets and why they swim into them是為了找到海豚是否能否感應到漁網，為什么會鉆進漁網，故選A．
63．B．細節(jié)題，結合By working slowly and rewarding the dolphins with fish，the animals grow comfortable in swimming with their eyes covered at last．可知是獎勵魚，故選B．
64．A．細節(jié)題，結合But I think all of the dolphins with their eyes covered can listen to sound cues （暗號） that help them find their way around by using passive listening．可知是通過被動傾聽，故選A．
65．D．細節(jié)題，結合Further experiments will have the dolphins swim through an obstacle （障礙物） field of good objects that won't hurt the animals，such as nets，ropes in the water．進一步實驗是讓海豚游過不會傷害動物的障礙物，故選D．
點評 在做英語閱讀時，首先通讀全文，不要被某個或某些自己不熟悉的單詞所困擾，了解大概意思．然后看問題，帶著問題精讀全文，同時選擇答案，必要時用排除法，注意，文章中一般都會有答案，有的可以直接找到，英美人并不愿意把問題弄得太深奧，不必想得太復雜，很多都是直接了當的，千萬別自己發(fā)揮想象．但不得不說，平時多積累詞匯量的話，答題可能就會主動一些，有把握一些．
