Question

    Now, let’s talk about earthquakes on our planet. Some countries have large numbers of earthquakes. Japan is one of them. Others do not have many. For example, there are few earthquakes in Britain. There is often a great noise during an earthquake. The ground vibrates (震动). Houses fall down. Trains run off the lines. Sometimes, there is a heavy loss of human lives.

Earthquakes often happen near volcanoes, but this is not always true. The centers of some earthquakes are under the sea. The bottom of the sea suddenly moves. The powerful forces inside the earth break the rocks. The coast is shaken and great waves appear. These waves, also known as seismic waves(地震波), or tsunamis(海啸) can travel long distances and rush over the land when they reach it. They are strong enough to break down houses and other buildings. Very often fires follow the most serious earthquakes. In 1906, the numbers of fires were burning in the city. The water pipes were also shaken and broken, so it was not possible to put the fire out. There was no water. The Tokyo Earthquake of 1923 happened just before noon. People were cooking meals on their fires at that time. When the ground shook, the fires shook, too. Hot materials were thrown on the different parts of the houses, some of which were made of wood. Soon 134 fires were burning in the city.

What kind of building stands up best in an earthquake? A building with concrete walls is perhaps the best. A steel frame will make it even stronger. The frame holds the different parts together and the walls so not easily fall. There is less chance of fire because concrete and steel do not burn. Over the years, scientists studied the results of the earthquake in different parts of the world, and they are convinced that this kind of building is the safest.

1.What can we know about earthquake from the first paragraph?

A.Britain has large numbers of earthquake.

B.There is often a great noise during an earthquake.

C.There is a heavy loss of human lives in every earthquake.

D.Trains will not run off the lines during the earthquake.

2.Some of the undersea earthquakes were caused by ______.

A.the breakout of the volcano B.the seismic waves

C.the tsunami D.the powerful forces inside the earth

3.What can be inferred from the last paragraph?

A.A building with concrete walls and a steel frame stands up best in an earthquake.

B.There is no chance of fire in a building with concrete walls.

C.Scientist studied the causes of the earthquake to get the conclusion.

D.A steel frame has no help in making the house stronger.

4.This text is probably a ______.

A.book review B.popular science report

C.newspaper ad D.fairy tale

Answer

1.B

2.D

3.A

4.B

【解析】

这是一篇说明文。文章是关于地震的，介绍了地震发生的地区，地震波的威力，以及怎样的建筑抗震效果好的的等。

1.细节理解题。由第一段There is often a great noise during an earthquake.可知地震期间会有巨大声响。故选B。

2.细节理解题。由第二段The powerful forces inside the earth break the rocks.The coast is shaken and great waves appear. These waves, also known as seismic waves(地震波), or tsunamis(海啸) can travel long distances and rush over the land when they reach it. They are strong enough to break down houses and other buildings. Very often fires follow the most serious earthquakes.可知地球内部的强大力量能打碎巨石，海岸被摇动，巨浪出现。这些波，也被称为地震波，或海啸可以长途跋涉，当它们到达陆地时就会冲过陆地。它们足够强大，足以摧毁房屋和其他建筑物。火灾往往伴随着最严重的地震。所以一些海底地震是地球内部的力量造成的。故选D。

3.推理判断题。由最后一段What kind of building stands up best in an earthquake? A building with concrete walls is perhaps the best. A steel frame will make it even stronger.可知在震中什么样的建筑承受力最好？有混凝土墙的也许最好。钢架结构会更坚固。所以混凝土墙和钢架结构的建筑在地震中承受力最好。故选A。

4.推理判断题。由第一段Now, let’s talk about earthquakes on our planet.可知，现在，我们来讨论一下我们星球上的地震。所以文章是关于地震的，在科学杂志上最可能读到。故选B。
