Question

Can a fish hear fishermen moving along the stream? What are the facts about the ability of a fish to see? Can they tell the difference between colors?
The sharp hearing of a fish has been proved by two scientists, who trained a fish to expect its food when it heard the sound of a whistle. And a slight sound two hundred feet away could drive fishes away. That should make fishermen start thinking.
One scientist had made experiments to prove fish can recognize different colors such as red, brown, yellow and green.
Fish also have an eye for different shapes. One scientist proved this by teaching fish to connect certain patterns with food. He used a small circle and a square. If the fish swam towards the circle, they received food as a reward. If they swam towards the square, they received nothing. The fish learned in time to go to the circle but not to the square. Does this mean that in time fish might learn to leave alone all food on hooks that they have seen often before? Here is something for all fishermen to think about!
These facts help to make more believable some of the “believe it or not” stories that have been told about fish. It is clear that fish have sometimes shown their ability to gain knowledge as man does. A good example of what we might call “thinking” by a fish is given by an experience of Dr. Andrew Gage. Fishing over a bridge, he hooked a fish. It struggled and dragged the line two hundred feet away before he stopped it. Then it swam back to the bridge. The clever fish then swam round a pile and, with a sudden push, broke the line. If the story ended there, one could say that the fish had freed itself by chance. However, Gage went on fishing. Below him he could see the fish that had broken loose. After another twenty minutes the fish again seized the food on the hook. This time it did not swim out but swam round one of the piles and again broke the line.
Many stories are told of the fish that get away and the clever “old hand” ones that can’t be caught. The more often a fish is nearly caught, the more difficult it will be to interest it next time.
【小題1】The last two paragraph’s mainly discuss _________.

A．whether a fish can think as man does

B．how a fish could escape from danger

C．how to catch a fish more easily

D．whether a fish is believable

【小題2】 What’s the best title of the passage?

A．Fish can hear and see

B．How clever is a fish?

C．Fish can play tricks

D．How scientists help fishermen.

【小題3】We can infer from the last paragraph that _________.

A．it’s difficult to catch fish;

B．fish are cleverer sometimes than fishermen

C．fish seem to learn by their experience

D．fewer people will be interested in fish

Answer 1

【小題1】 A
【小題2】 B
【小題3】 C

解析試題分析：本文是一篇關(guān)于魚的研究發(fā)現(xiàn)。魚的聽覺很敏感。一個科學(xué)家通過實驗證明：魚是能辨別不同的顏色。魚能辨別形狀。還有令漁夫們值得思考的問題：魚能脫鉤而逃。種種發(fā)現(xiàn)表明：魚就和人一樣聰明。
【小題1】推理判斷題。最后兩段主要討論魚是否有能力和人一樣會思考。聰明的魚會脫鉤而逃。第五段第二句：It is clear that fish have sometimes shown their ability to gain knowledge as man does. 很清楚魚有時會表現(xiàn)出它們和人一樣有獲取知識的能力。故選A。
【小題2】標題歸納題。本篇文章根據(jù)全文內(nèi)容，尤其是第五段判斷：通過該段的魚脫鉤的經(jīng)歷描述和最后一段判斷：通過全文閱讀判斷最佳題目應(yīng)該是：魚到底有多么聰明？故選B。
【小題3】推理判斷題。根據(jù)第四段的故事和全文最后一句話：The more often a fish is nearly caught, the more difficult it will be to interest it next time.魚越是經(jīng)常差一點就被捉，下一次就越難使它（對魚餌）感興趣。判斷魚似乎是根據(jù)經(jīng)驗擺脫魚鉤的。故選C。
