An earthquake happens when two plates rub (碰撞) together. The earth plates travel in different directions and at different speeds. If one plate is slowly forced underneath the other,  pressure builds up until the plates break apart. This process causes the ground to move. It is an earthquake. In other words, earth-quakes are the shaking of the earth’s surface caused by the earth’s rocky outer layer as a result of the energy stored within the earth. The strain within the rocks is suddenly released (释放).

The damage an earthquake causes depends on where it is and the time it is happening. If an unpopulated region is struck, there will be low loss of life or property. If it hits a large city, there may be many in-juries and much destruction. Many of the areas at risk are largely populated now. Major earthquakes hitting those areas today could produce terrible damage.

Actually, there are several million small earth-quakes every year.  Large earthquakes such as the 1964 Alaskan quake that measured 9.2 on the Richter scale, cause millions of dollars in damage. In the last 500 years, millions of people have been killed by earth-quakes around the world — including 240,000 in the 1976 Tangshan earthquake in China.

A 60-second or less earthquake can cause devastation that continues for years after the first tremor (小震). In 1972, a series of severe earthquakes struck Managua, Nicaragua. Fifteen years later, the city still looked the way it had a week after the earthquake hit, because the country did not have the necessary money to rebuild it.

The shaking of the earth is sometimes not the greatest disaster. It is in the ensuing fires and floods that often the greatest damage occurs. In the 1906 earthquake, it was the fires caused after it that did the majority of the damage. An earthquake can also destroy dams high above a city or valleys, causing floods to sweep down and sweep away everything in their path.

1.Which of the following is the main idea of the first paragraph?

2.How many examples are used in the passage to show the damage and destruction earthquakes cause?

3.Which of the following is mentioned to show that an earthquake can kill too many people?

4.The underlined word “ensuing” in the last paragraph probably means ______.

5.By giving the example in Paragraph 4, the author wants to show that ______.

Do astronauts get space sick when they travel from Earth to the International Space Station (ISS)? Yes, astronauts can get space sick travelling to the ISS. It is less likely travelling in the cramped (拥挤的) Russian Soyuz spacecraft used to transport astronauts there now, than the old Space Shuttle that was used until 2011. The ability to move around in the Space Shuttle increased the chance of space sickness happening.

As you probably know, gravity is lower inside the ISS. The low gravity in space allows astronauts to float around, which looks like fun, but it can help cause space sickness.

Recent experiments show that space sickness is related to our inner ear. Two separate parts of the inner ear respond to sudden changes in direction. If you shake or move your head very quickly, you can get dizzy. However, this normally passes very quickly. This normal response is upset under low gravity: your inner ear thinks you are constantly moving. It takes some time to adapt to the new condition of weightlessness. It is made worse if you move your head while your body is still adapting. This is why previous astronauts travelling in the larger Space Shuttle were likely to suffer from space sickness more than the current astronauts travelling in the cramped Soyuz spacecraft. The astronauts were less likely to move their heads around very much in a narrow space.

Space sickness was not talked about in the early space missions (任务).The original Mercury and Gemini spacecraft were, like the current Soyuz, cramped. The astronauts were less likely to get sick, so space sickness no longer became a concern of NASA.

In 1983 the first detailed study was carried out aboard a Space Shuttle flight (STS-7) by astronaut-doctor Norm Thagard. His and all later studies were hampered by the astronauts themselves. None of them wanted admit to being space sick. They were worried that mission control might remove them from space walking opportunities, or even worse, that they might not get included on later space missions.

1.What was the problem with the Space Shuttle?

A.It was too slow.

B.It was too small.

C.It broke down often.

D.It had too much space.

2.How does low gravity hurt astronauts?

A.It fools their inner ear.

B.It causes pain in their head.

C.It stops them shaking their head.

D.It prevents them measuring their weight.

3.Why wasn’t NASA worried about space sickness until later missions?

A.The condition had been kept secret to the public.

B.There were few detailed studies on it.

C.The old spacecraft were better equipped.

D.The astronauts were less likely to get sick.

4.What does the underlined word “hampered” in the last paragraph mean?

A.Changed. B.Improved.

C.Blocked. D.Compared.

When I was in primary school, I was told that the earth ______around the sun.

高二英语单项填空简单题查看答案及解析

When we look at the sky and see a bright light moving quickly across it or coming towards the earth, we talk about seeing a “shooting star” or a “falling star”. These moving lights are not, in fact, stars at all. They are small pieces of matter from outer space, which burn up as they enter the Earth’s atmosphere. The correct name of them is meteoroids. Any pieces that make it to the Earth’s surface without completely burning up are known as meteorites. A meteor is actually the name given to the light we see when a meteoroid is burning up.

When a meteorite hits the Earth at speeds between 11 and 72 kilometers a second, it can do amazing damage. A very large meteorite could knock the earth out of its orbit. If this happened, all life on Earth would probably become extinct（灭绝）. The path we follow around the Sun would change and as a result the Earth would become either much hotter or much colder. This change in temperature would affect sea levels and the amount of water in rivers. There would either be huge floods, which would cover most of the land with water, or the oceans would dry up and there would be a drought, which means a long period of time without rain. Either way, nothing could survive. If a large meteorite landed in the sea it would almost certainly cause tsunamis, which would race towards the land, destroying everything in their paths.

Although it is unlikely the Earth will be struck by a meteorite large enough to do that kind of damage, there is evidence of fairly large meteorites hitting the Earth in the past. In 1908 a large area of forest in Tunguska, Siberia was destroyed by a meteorite that came apart just before it hit the ground. The moon, however, has about three billion craters陨石坑caused by meteorites impacting影响 its surface. The reason more meteorites have reached the surface of the moon than the surface of the Earth is that the moon does not have enough atmosphere for the meteorites to burn up in. some of the meteorites that have reached the Earth’s surface have done considerable damage. Some scientists believe it was a change of climate caused by meteorites hitting the Earth that resulted in the extinction of the dinosaurs and other large prehistoric animals.

Scientists are especially interested in meteorites because they contain information about the solar system. It is widely believed by scientists that most meteorites are produced by collisions（碰撞） between asteroids (small planets). These collisions probably happened many billions of years ago. This means the physical and chemical structure of a meteorite can give scientists information about the early days of the universe.

1.The story is about ___.

2.The Earth has ___.

3.Some scientists believe the dinosaurs became extinct because ___.

4.Meteors are ___.

Travel Tips for New Zealand

If you’re looking for some adventure in one of the amazing countries on Earth, then New Zealand is a must! 1.! But there are a few things you should know before you head over to it.

1. Bring every kind of clothing you own

That might be a bit surprising, but we have some crazy weather here. From snow in Southland, to windy Wellington, to Auckland, you may experience four seasons in one day! You’d be forgiven for thinking that you could just bring your hot weather clothes if you’re here in the “summer months”. 2..

2. New Zealand beaches are amazing, but dangerous

New Zealand has some of the most beautiful beaches in the world, and it’s not uncommon to have a whole beach for yourself. Sadly though, I’ve seen countless tourists on the news who have underestimated (低估) our beaches and ended up having to be rescued, or worse. Though a lot of the beaches are popular destinations, make sure you read the signs or ask a local to make sure it’s safe. 3. You’ll soon find out that the sun in New Zealand might not be as hot, but you’ll burn a lot faster than anywhere else.

3. 4.

Sure, there are plenty of tours that you can go on to see different parts of the country, but by hiring your own car, you’ll have the freedom of the open road. 5.. So, getting around is much easier with your own car and you’ll be able to come and go as you please. Don’t forget to drive on the LEFT side of the road down here!

A. It really is a country like no other

B. Also remember to apply sunscreen (防晒霜)

C. You will need a car to get around

D. You will come back to New Zealand for more

E. New Zealand’s public transport is not good enough

F. But summer often doesn’t truly kick in until mid-late January, and even then it’s touch-and-go

G. If you go for a bush walk in New Zealand, your biggest danger is slipping on some rocks or getting lost
