Question

【題目】

You probably know many of the things that you can do with the hundreds of different muscles in your body. But have you ever thought about how the muscles in an animal’s body are different from yours? An animal’s muscles are made to do the things that are most important for its life.

Lions are hunters. They depend on their ability to catch other animals. Lions must be fast in order to catch their prey(獵物). The powerful muscles in their back legs allow them to run at speeds of more

than 30 miles per hour. They can also jump a distance of more than 35 feet. The strong muscles in their front legs help them catch their prey.

Snakes also use their muscles for hunting prey and for movement, but their muscles work in very different ways than lions’ do. Because snakes do not have any legs, they use their muscles to push against the ground or other objects to move themselves forward. Their muscles also allow them to eat things that seem much too large. For example, a snake may eat an egg that is larger than the width of its body. How does this happen? The snake’s strong neck muscles work together to push the egg down the mouth.

The elephant’s long nose has a lot of muscles. Scientists believe that the nose alone has more than 100,000 muscles! This is because the elephant uses its nose much in the same way that people use their hands and fingers. Even though the nose is large, it can perform surprisingly tasks. For example, an elephant can pick up a small leaf from the ground. The nose can also be a powerful tool. An elephant can use its nose to pick up a tree by its roots or even to lift a baby elephant.

The great muscles of these animals seem pretty unbelievable. But the muscles in your body work exactly the way you need them to. After all, it might be fun to be able to jump a distance of 30 feet, but as a human being, there is just not much need for it.

Answer 1

【答案】

【1】C

【2】B

【3】D

【4】B

【解析】本文主要介紹了肌肉對(duì)動(dòng)物生命的重要性，同時(shí)動(dòng)物的肌肉與人的肌肉做了對(duì)比。

【1】題意：第2段中的劃線詞“hunters”是指以_________的人或動(dòng)物�？疾榧�(xì)節(jié)理解能力。A. keep animals for fun 為了樂趣飼養(yǎng)動(dòng)物；B. raise animals for meat飼養(yǎng)動(dòng)物為了吃肉；C. catch animals for food捕捉動(dòng)物作為食物；D. run after animals for exercise為了鍛煉追趕動(dòng)物。根據(jù)下文They depend on their ability to catch other animals. Lions must be fast in order to catch their prey(獵物).（他們依靠自己的能力捕捉其他動(dòng)物。為了捕捉獵物，獅子要快。）結(jié)合語境可知獅子是獵手，hunters的意思是捕捉動(dòng)物作為食物。選C。

【2】題意：在文章中，除了__________________________，所有這些都在討論中�？疾榧�(xì)節(jié)理解能力。A. An elephant’s nose is strong enough to pick up a tree by its roots. 大象的鼻子足夠強(qiáng)壯，可以從根部拔起一棵樹；B. The strong muscles in the back legs help lions catch their prey. 后腿強(qiáng)壯的肌肉幫助獅子捕捉獵物；C. Snakes can’t move themselves forward without their muscles. 蛇沒有肌肉不能向前活動(dòng)；D. Muscles in an animal’s body are different from a human’s. 動(dòng)物身體的肌肉與人類的肌肉不同。根據(jù)第四段最后一句An elephant can use its nose to pick up a tree by its roots or even to lift a baby elephant.可知A在文中談及了；根據(jù)第三段第二句Because snakes do not have any legs, they use their muscles to push against the ground or other objects to move themselves forward.可知C在文中談及到；根據(jù)第一段特別是第二句But have you ever thought about how the muscles in an animal’s body are different from yours?（但是你有沒有想過動(dòng)物體內(nèi)的肌肉和你的肌肉有什么不同呢？）和最后一段可知D在文中談及到；根據(jù)第二段第5句The strong muscles in their front legs help them catch their prey.（前腿強(qiáng)健的肌肉幫助它們捕捉獵物。）可知B在文中沒有談到，故選B。

【3】題意：根據(jù)文章，是什么使你的身體肌肉不同于動(dòng)物的肌肉？考查細(xì)節(jié)理解能力。A. The exercise. 運(yùn)動(dòng)；B. Your parents. 你的父母；C. The environment. 環(huán)境；D. Your needs. 你的需要。根據(jù)最后一段第二三句But the muscles in your body work exactly the way you need them to. After all, it might be fun to be able to jump a distance of 30 feet, but as a human being, there is just not much need for it.（但是你身體的肌肉正以你所需要的方式工作。畢竟，能夠跳30英尺遠(yuǎn)是很有趣的，但作為一個(gè)人，卻沒有太多的需要。）結(jié)合題意、語境和選項(xiàng)可知選D。

【4】題意：下列哪一項(xiàng)顯示了這篇文章的結(jié)構(gòu)？考查綜合理解能力。本文結(jié)構(gòu)是總分總，第一段介紹了動(dòng)物的肌肉是用來做對(duì)生命最重要的東西的。第2,3,4段舉例說明肌肉對(duì)動(dòng)物的重要性；第5段動(dòng)物的肌肉與人的肌肉進(jìn)行了對(duì)比。結(jié)合題意和選項(xiàng)可知選B。
