Question

【題目】Dolphins are not fish. They are mammals (哺乳動(dòng)物). They live in groups and speak to each other in their own language. But they are quite different from almost all the animals. Their brain(大腦) is as big as man’s and they live a long life — at least 20 or 30 years.

Like some animals, dolphins use sounds to help them find their way around. They also use these sounds to talk to each other and to help them find food. They do not use their ears to get sounds, but use the jaw — the lower part of the mouth.

Dolphins are friendly to man, and for thousands of years, there are many stories about dolphins and man. In the 19th century, in a dangerous part of the sea near New Zealand, there was a dolphin. The seamen liked him very much and gave him a very good name, Jack. From 1871 to 1903, Jack met every boat in the area and showed them the way. In 1903, a passenger(乘客) on a boat with the name “The Penguin” shot and hurt Jack. Luckily the dolphin didn’t die, and after a long time he was well again. He helped the ships find the way through the area for nine more years, but he didn’t help the boat “The Penguin”.

Today, some people still kill dolphins, but many countries in the world now protect them. In these places, people mustn’t kill them.

【解析】本文是一篇說(shuō)明文，主要介紹了海豚。海豚不是魚(yú)，它們是哺乳動(dòng)物，過(guò)著一種群居的生活。海豚與所有陸生動(dòng)物都不同，他們的大腦與人類(lèi)一樣大，并且壽命也很長(zhǎng)--至少能活20-30年。海豚通過(guò)聲音確定方向的，通過(guò)聲音來(lái)相互交談，并幫助它們尋找食物，它們不使用自己的耳朵接收的聲音，而是使用下顎。海豚對(duì)人類(lèi)很友好。

【1】詞義猜測(cè)題。根據(jù)文中語(yǔ)句“They do not use their ears to receive sounds, but use the jaw--the lower part of the mouth.”理解可知，嘴巴較低的部位就是下顎，答案為A。

【2】細(xì)節(jié)理解題。根據(jù)文中語(yǔ)句“Like some animals, dolphins use sounds to help them find their way around.”理解可知，海豚通過(guò)聲音幫助它們找到方向，故答案為B。

【3】細(xì)節(jié)理解題。根據(jù)文中語(yǔ)句“In the 19th century, in a dangerous part of the sea near New Zealand, there was a dolphin. The seamen liked him very much and gave him a very good name, Jack.”理解可知，Jack是一只海豚的名字，故答案為D。

【4】數(shù)字計(jì)算題。根據(jù)文中語(yǔ)句“From 1871 to 1903 ,Jack met every boat in the area and showed it the way. 和He guided the ships through the area for nine more years,”理解可知，從1871到1903是32年，后來(lái)又經(jīng)過(guò)了9年，Jack這只海豚前后共計(jì)41年給船只導(dǎo)航，故答案為D。

【5】細(xì)節(jié)判斷題。節(jié)理解題，根據(jù)文中語(yǔ)句“They live in groups and speak to each other in their own language.”理解可知，海豚過(guò)群居的生活，故C答案錯(cuò)誤。
