Question

We’ve talked about snails (蜗牛) and their slow move. But much of the time snails don’t move at all. They’re in their shells ---sleeping .

Hot sun will dry out a snail’s body. So at the least sign of hot sun, a snail draws its body into its shell and closes the opening with a thin cover. Then it goes to sleep. A snail will die in a heavy rain. So whenever it rains, it goes inside its shell house and goes to sleep. A snail can sleep for as long as it needs to. It can take a short sleep. Or it can sleep for days at a time. And it spends all the winter months in its shell, asleep.

In spring the snail wakes up. Its body, about three inches long, comes out of from the shell. When hungry, the snail looks for food. It can’t see very well. Its eyes, at the ends of the top feelers are very weak. But its sense of smell is very strong. It helps the snail to the new greens. Then the snail’s little mouth goes to work.

A snail’s mouth is no longer than the point of a pin(针). Yet it has 256,000 teeth! The teeth are so small that you can’t see them. But they do their work.. If you put a snail in a hard paper box, it will eat its way out. And if a snail wears out its teeth, it will grow new ones.

Mostly, a snail looks for food at night .But on cloudy days it eats in the daytime. It eats all day long. A snail can go on eating for hours and never feel full.

【解析】

试题分析：这篇短文是关于蜗牛的。蜗牛大部分的时间都在睡觉，不管是晴天还是雨天，它都缩在壳里睡觉，冬天还会冬眠。春天它就醒了，用它的嗅觉来寻找食物。蜗牛有很多牙齿，可以用来吃东西， 而且牙齿会更换。它一般晚上寻找食物。

1.细节理解题。文中第一段But much of the time snails don’t move at all. They’re in their shells ---sleeping.但是打部分时间蜗牛是一动不动的，他们躲在壳里睡觉，所以选D，它们大部分时间在睡觉。

2.词意猜测题。句意：蜗牛把身子缩回壳里。A用笔画，B远离；C拉，D移到尾端，C最符合句意。

3.细节理解题。从文中第三段It can’t see very well.它看不太清楚。从而选B。

4.判断推理题。从文中第二段A snail will die in a heavy rain. So whenever it rains, it goes inside its shell house and goes to sleep.大雨可以导致蜗牛死亡。所以不管什么什么下雨，它都躲在壳里睡觉，从而判断D正确。

5.判断推理题。文中第四段And if a snail wears out its teeth, it will grow new ones.如果蜗牛的牙齿掉了，会长出新的，由此得知蜗牛的牙齿会掉的，所以C选项错误。
