二、阅读理解（共4小题；每小题5分，满分20分）
Natural Disasters
Earthquakes are natural disasters. They are the shaking of the earth’s surface(表面). The earth makes these natural earthquakes in order to release pressure(释放压力).
More than a million earthquakes happen in the world each year. Earthquakes usually last less than a minute but you can feel them. The scary thing about earthquakes is that they begin with no warning. But scientists are still working on the problem.
There are about 20 plates(板块) along the surface of the earth that move slowly all the time next to each other. When the plates touch each other, huge rocks are created(创造) and explode(爆炸) with great power(力量), causing an earthquake. As the plates move, they put pressure on themselves and each other. When the pressure is large enough, the crust(地壳) is forced(被迫) to break.
Shaking and ground breaking are the main effects(影响) created by earthquakes. After an earthquake is over, buildings are usually damaged(破坏) and people get hurt even killed.
Some people think animals can predict(预言) an earthquake. The earliest reference(参考) about unusual animal behavior is from Greece in 373 BC. Rats and snakes reportedly left their homes and headed for safety several days before an earthquake. Scientists can easily explain the cause of unusual animal behavior seconds before humans feel an earthquake. Very few humans notice the smaller P wave that travels the fastest from the earthquake source(源) and arrives before the larger S wave. But many animals are able to feel the P wave seconds before the S wave arrives. As for sensing an earthquake days or weeks before it happens, that’s a different story. Scientists have tried many different ways of predicting earthquakes, but none have been successful. They need to do much research on this subject.
So what should you do when an earthquake begins If you are inside a building, you should take cover under a table. If you are outside, you should stay out in an open place.
11.An earthquake happens because ________.
A.the earth wants to release pressure
B.there are more creatures on the earth
C.there are about 30 plates along the surface of the earth
D.people damaged the surface of the earth
12.What is the third paragraph mainly about
A.The places of earthquakes. B.The reasons for earthquakes.
C.The ways of predicting earthquakes. D.The bad result of an earthquake.
13.Some animals ________ so they leave their homes to safe places before an earthquake.
A.are very clever
B.can create an earthquake
C.like living in new places with their friends
D.can feel the P wave seconds before the S wave arrives
14.The writer probably agrees(同意) that ________.
A.we should protect the animals before earthquakes
B.scientists can know earthquakes before they happen
C.people should learn to keep safe during earthquakes
D.earthquakes are the most dangerous natural disasters
