Tornadoes(龙卷风) are one of the worst weather events on earth. Each year, tornadoes kill many people. The storms often carry homes, cars and trees from one place to another. And they can also destroy anything when they pass by.

A tornado comes from a thunderstorm(雷雨) in the sky down to the ground. It is big at the top and small at the bottom.

A tornado appears when winds in different directions meet in the cloud and begin to turn in circles. People can see tornadoes almost everywhere in the world. But most happen from late winter to middle summer. There is a second high season in November. During spring, warm air moves north and mixes with the cold air left from winter. In November, the opposite happens. Cold air moves south and mixes with the warm air left from summer.

Tornadoes always come suddenly. Weather scientists have done something to predict(预测) tornadoes. But the storms often move too fast for people to protect themselves. Last year, tornadoes killed more than one hundred people in United States.

Scientists say the best place to be in is a small room, without windows, in the middle the lowest part of a building when tornadoes come.

Earth Day is an event most commonly celebrated on the 22nd of April each year. It is a day on which people around the world take part in activities aiming at raising public attention about our mother planet and how to protect it.

1.　　

Below, we have listed 4 things you can do to make this a better place, a better world for the future generations.　

▲ Leave your cars at home

Cars, being the greatest source of air pollution, can be left at home this weekend. Travelling by public transport is the better choice.

2.

▲ Be a little dirty

3.

A daily shower isn’t a matter of health; it’s a matter of comfort. Showering every day can wash away the natural oils that our skin and hair need.

One of the greatest mysteries on Earth is the statues which stand on Easter Island. Easter Island, which was almost uninhabited when it was discovered on Easter Day in 1722 by a Dutch captain, is the most distant island in the world covered with hundreds of giant statues, each weighing several tons and some standing more than 30 feet tall.

Who built these statues and why and how did they get there? Nobody knows the answer for sure.

One theory suggests that Easter Island was first inhabited by Polynesians, who traveled thousands of miles in their canoes（独木舟）in 400 A.D. However, the ocean currents（洋流）which carried them there would not take them back, so that they could not leave.

The statues appear to have been made out of the top edge of the walls of a volcano on the island. Then, it may have been rolled or dragged down to the foot of the volcano(火山). Then, it was stood upright（直立）and ropes were tied around it, which was made to act as a pulley（滑轮）. Over a period of months, a statue could be walked for miles down to the ocean. Finally, it was placed in line with other statues, all of them looking towards the center of the island.

This process was difficult. If a statue fell over, it was too heavy to be pulled upright again, so the islanders went back and carved another statue.

The population of Easter Island must have reached 11,000. Later, the resources of the island were used up and people began fighting and eating each other. Work on the statues stopped and the statues were knocked over. When the first Europeans finally arrived on the island, most of these people had died out.

1.This passage is mainly about ________ .

A. the discovery of Easter Island             B. the statues on Easter Island

C. the history of Easter Islanders             D. the earliest population on Easter Island

2. Which of the following correctly tells of the possible working process after a statue was made?

a. It was stood upright and ropes were tied around it.

b. It was walked for miles down to the ocean.

c. It was placed in line with other statues.

d. It was moved to the foot of the volcano.

A. c-d-a-b             B. d-b-a-c          C. a-c-b-d            D. d-a-b-c

3. It’s not a fact that ________ .

A. Easter Island is the most distant island in the world

B. Easter is the name of a holiday

C. not all the statues were placed in a line

D. the island was once rich in natural resources

4.The underlined word uninhabited most probably means ________.

A. mysterious                                 B. lost

C. unknown to the world                             D. with no people living there

The sun is always shining. But it can only shine on one side of the earth at one time. When the sun is shining on one side of the earth, it is night on the other side. At night, you can see the stars. The stars are in the sky all day. But the light from the sun is so bright that you can’t see them. When night comes, there is no light, and the stars are bright enough to see. The stars look very small. But some of them are even bigger than the sun. They look small because they are so far away from you. Big things look much smaller when they are far away. The sun is closer to the earth than other stars, so it looks bigger.
