Question

We’ve talked about snails (蝸牛) 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(針). 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】

試題分析：這篇短文是關于蝸牛的。蝸牛大部分的時間都在睡覺，不管是晴天還是雨天，它都縮在殼里睡覺，冬天還會冬眠。春天它就醒了，用它的嗅覺來尋找食物。蝸牛有很多牙齒，可以用來吃東西， 而且牙齒會更換。它一般晚上尋找食物。

1.細節理解題。文中第一段But much of the time snails don’t move at all. They’re in their shells ---sleeping.但是打部分時間蝸牛是一動不動的，他們躲在殼里睡覺，所以選D，它們大部分時間在睡覺。

2.詞意猜測題。句意：蝸牛把身子縮回殼里。A用筆畫，B遠離；C拉，D移到尾端，C最符合句意。

3.細節理解題。從文中第三段It can’t see very well.它看不太清楚。從而選B。

4.判斷推理題。從文中第二段A snail will die in a heavy rain. So whenever it rains, it goes inside its shell house and goes to sleep.大雨可以導致蝸牛死亡。所以不管什么什么下雨，它都躲在殼里睡覺，從而判斷D正確。

5.判斷推理題。文中第四段And if a snail wears out its teeth, it will grow new ones.如果蝸牛的牙齒掉了，會長出新的，由此得知蝸牛的牙齒會掉的，所以C選項錯誤。
