Question

【题目】阅读下面短文，根据短文内容判断句子的正误。
Here are some of the fastest animals in the animal world. As you read about them, remember that top speed of hummer runners is 20 to 25 miles an hour. And the fastest human runner can only run at this speed for a few hundred meters.

	Heavy people do not run very fast. But some heavy animals can run at amazing speed. Black rhinos can run at a speed of almost 30 miles an hour, even though they may weigh over 3,500 pounds.
	Cheetahs are the fastest land mammals (哺乳动物) over short distances (距离). They can run at a speed of over 70 miles an hour. But they can get tired quickly and usually stop after a few hundred meters.
	Pronghorn antelopes are the fastest land mammals over long distances. They can run at a speed of 35 miles an hour for many miles. Their top speed is probably more than 50 miles an hour.
	Hummingbirds are the smallest birds. But they move their wings (翅膀) faster than other birds. Some of them beat their wings 4,500 times a minute.
	Ostriches can't fly, but they can run faster than other birds and most other animals as well. They can run at a top speed of 43 miles an hour for a short distance, but can keep up a speed of more than 30 miles an hour over long distance. They are also the largest of all birds, and they lay the largest eggs.

（1）Black rhinos can run faster than the fastest human runners.
（2）Though cheetahs run very fast, they get tired soon.
（3）Pronghorn antelopes are the fastest animals over short distances.
（4）Hummingbirds move their wings faster than other birds because they are large.
（5）Ostriches can run fast over long distances.

Answer 1

【答案】
（1）正确
（2）正确
（3）错误
（4）错误
（5）正确
【解析】本文介绍了动物世界中一些跑得最快的动物。人太重跑不快，但有些重的动物可以以惊人的速度跑如黑犀牛。猎豹是陆地上短距离跑速度最快的哺乳动物。叉角羚羚羊是陆地上长距离跑速度最快的哺乳动物。蜂鸟是最小的鸟。但是他们可以一分钟拍打翅膀4500次。鸵鸟不能飞，但他们可以跟其他鸟类和其他动物一样跑。他们也是最大的鸟类。
（1）that top speed of hummer runners is 20 to 25 miles an hour人类当中最快的奔跑速度达到每小时20-25英里， 而Black rhinos can run at a speed of almost 30 miles an hour,黑犀牛可以跑到每小时30 英里，可知黑犀牛比人类跑得快，故正确。
（2）根据文中信息They can run at a speed of over 70 miles an hour. But they can get tired quickly and usually stop after a few hundred meters.可以每小时跑70多英里。但是他们很快就会累，跑几百米之后就会停下来，所以此题正确。
（3）根据文中信息Pronghorn antelopes are the fastest land mammals over long distances.叉角羚是长跑中最快的，所以此题错误。
（4）根据文中信息Hummingbirds are the smallest birds.蜂鸟是最小的动物，所以此题是错误的。
（5）根据文中信息but can keep up a speed of more than 30 miles an hour over long distance.鸵鸟在长跑中可以达到每小时30多英里。所以此题正确。
