Question

Of all the animals in the animal kingdom, which one (aside from man) is the cleverest?
There are several ways of measuring the intelligence of animals. In one test a scientist sets three same cans on a table. While the animal watches, he puts food under one of the cans. Then he leads the animal away. Some time later, he brings it back to see if it remembers which can has the food. No smelling is allowed; the animal must go directly to the correct can or it fails.
This is called a delayed-response test. The idea is to find out how long an animal’s memory can keep information. The scientists would try showing the cans to the animal one hour later, or two hours later, or even a full day later. They discovered that chimpanzees and elephants have the best memory, and were able to remember the correct can for at least twenty hours. No other animal is close. Dogs came next, but they only remember for nine hours.
To settle the matter, the scientists designed a huge maze (迷宮) and ran the chimps and elephants through it. The maze was very difficult, with many blind paths and dead ends. It took the chimps ten minutes to find their way out. The elephants needed half an hour. Even allowing for the elephants’ slower rate of speed, the test shows that chimpanzees are the cleverest animals.
From this and other tests, the scientists drew the following conclusion: an animal’s intelligence depends on the size of its brain in proportion (比例) to the size of its body. The elephant’s brain weighs ten pounds. But this is only 1/600th of its 6,000 pounds body. A chimp’s brain weighs about one pound, or 1/120th of its total body weight. So in proportion to its body size, the chimp has four times as much brain as the elephant----more brain for less body. The chimp is the champ!

【小題2】C
【小題3】D
【小題4】C
【小題5】C

解析試題分析：文章主要想弄清什么動(dòng)物是最聰明的，通過研究表明，猩猩是最聰明的動(dòng)物，這主要的根據(jù)動(dòng)物的腦量和身體的比例決定的。
【小題1】標(biāo)題題：從第一段的句子：Of all the animals in the animal kingdom, which one (aside from man) is the cleverest?可知這篇文章講的是除了人類最聰明的動(dòng)物是什么。選B
【小題2】主旨題：從文章最后一句話So in proportion to its body size, the chimp has four times as much brain as the elephant----more brain for less body. The chimp is the champ!可知這篇文章主要想說明猩猩是最聰明的動(dòng)物，選C
【小題3】細(xì)節(jié)題：從第三段的句子：This is called a delayed-response test. The idea is to find out how long an animal’s memory can keep information. 可知延遲反應(yīng)的測(cè)驗(yàn)是為了弄清動(dòng)物的記憶力，選D
【小題4】細(xì)節(jié)題：從第四段的句子：It took the chimps ten minutes to find their way out. The elephants needed half an hour.可知大象比猩猩動(dòng)作慢，選C
【小題5】推理題;從最后一段的句子：The elephant’s brain weighs ten pounds. But this is only 1/600th of its 6,000 pounds body. 可知大象的腦子是身體的1/600，而這個(gè)犀牛的腦子是身體的1/700,所以犀牛沒有大象聰明，選C
