八年级英语单选题中等难度题查看答案及解析

When we feel the ground moves suddenly, it means that an earthquake may come. Many of the earthquakes first come under the sea and then happen anywhere on the earth. Especially they often happen near the mountains and seas such as Wenchuan, Japan and Indonesia.

When an earthquake happens, it’s very easy to cause a tsunami (海啸). Houses fall down, many people are injured and even died.

Now scientists are trying their best to study earthquakes. They make maps to show the“earthquake belts (地震带)”. So the houses there must be quite strong.

We believe that scientists will be able to tell us when and where an earthquake will happen in the near future. Also, they can tell us what to do and how to do. People can even use earthquakes to do something for us humans.

根据短文内容，判断下列句子的正（A）误（B）。

1.Earthquakes often happen in Japan.

2.Sometimes an earthquake happens with a tsunami.

3.Many people lost their lives in the earthquakes because they didn’t help each other.

D

When we get wet, we need a towel to get ourselves dry. When a dog gets wet, all it needs is to shake its body. A study in 2010 showed that a wet dog could throw off(甩掉) half the water on its body by shaking for less than a second. In fact, this common act of dogs works better than a washing machine.

The study found that animal shaking begins with the head and ends with the tail(尾巴). Smaller animals must shake faster than bigger animals to get water off. For example, in one second, a rat can shake 18 times, a dog 6 times, and a bear 4 times. Bigger animals can get their bodies dry with fewer shakes.

For animals, shaking is not just about getting themselves dry. It is also about saving their lives. Being wet makes animals heavier, and that makes it harder to run. In the animal world, if an animal is not able to run very fast, it may not live long. Maybe that's why the wet-dog shake" has become a common habit of many animals.
