题目列表(包括答案和解析)

How many things can you see in the night sky? A lot! On a clear night you can see the moon, some planets, and thousands of sparking stars.

You can see even more with a telescope. You might see that many stars look larger than others. You might see that some stars that look white are really red or blue. With bigger and bigger telescopes you can see more and more objects in the sky. And you can see those objects in more and more detail.

But scientists believe there are some things in the sky that we will never see. We won’t see them with the biggest telescope in the world, on the clearest night of the year.That’s because they’re invisible. They’re the mysterious dead stars called black holes.

You might find it hard to imagine that stars die. After all, our sun is a star. Year after year we see it up in the sky, burning brightly and giving us heat and light. The Sun certainly doesn’t seem to be getting old or weak. But stars do burn out and die after billions of years.

As a star’s gases burn, they give off light and heat. But when the gases run out, the star stops burning and begins to die.

So next time you look up at the night sky, remember: there’s more in the sky than we can see!

When visiting Beijing, the Palace Museum is a must-see for many people.

Last year, the museum received 14.2 million visitors, which is twice the number of visitors in 2002. This year it is expected to increase by 10 percent. Compared with other popular museums around the world, the number of visitors at the Palace Museum is very high. Last year the Louvre(罗浮宫) in Paris welcomed 8.8 million visitors and the British Museum in London received 5.8 million.

A large number of visitors can bring a lot of money from ticket sales. But there are also worries that people will do demage(破坏) to relics(文物) and old buildings.

To solve the problem, some people suggested taking cultural objects out of the Palace Museum. In this way, visitors coming for ancient buildings and cultural objects will go to different places. “It is a sign of progress. Letting more people see these treasures is more important than keeping them in their original(原始的) place,” said Song Xiangguang, a professor at Peking University.

However, Shan Jixiang, director of the Palace Museum, doesn’t agree on this idea. He thinks that the most important thing in protecting the Palace Museum is to keep it complete. “The 1.8 million cultural relics and the historical buildings are two key parts of the museum. They can’t be separated.” he said.

Shan said that they are planning to increase the space that is open to the public. This will not only feed visitors’ curiosity(好奇), but also spread them out so they are not putting too much pressure on one area.

Shan also wanted to set up an appointment system. “ If visitors make an appointment before they come, we can make better and different visiting routes(路线) for them.” Shan said.

1.How many visitors did the Palace Museum welcome in 2002?

A.14.2 million        B.8.8 million         C.5.8 million         D.7.1 million

2.Why did some people suggest taking cultural objects out of the Palace Museum?

A.To let more people see the relics.           B.To bring less damage to the relics.

C.To make more money from ticket sales.       D.To keep the Palace Museum original.

3.The underlined word “separated” means ______ in Chinese.

A.分离             B.破坏             C.偷窃             D.压迫

4.By reading the article, we can know that______________.

A.the Palace Museum has an appointment system now.

B.relics are the only important part of the Palace Museum.

C.the Louvre welcomed the most visitors in the world last year.

D.Shan thought that more areas of the palace should be open to public.

Disasters happen all the time somewhere in the world. Are you ready if one hits your neighborhood next week? Find out what you need to do now before it is too late. Let’s take an earthquake for example.

    During an earthquake, get under a strong object like the kitchen table. Don’t leave the building during the shaking, or you might be hurt by falling objects from the outside of the building.

    When you are in bed during the night and an earthquake happens,simply roll off the bed. There will be a safe void around the bed.

    If you are watching TV and you cannot easily run away by getting out through the door or window, then lie down and curl up(蜷伏) next to a sofa, or a large chair.

    Never go to the stairs. The stairs are likely part of the building to be broken. Even if the stairs are not destroyed by the earthquake,they may fall down later when people run down.

    Try to get into an open area away from trees,buildings,walls,advertisement boards and power lines if you are outdoors.

    If you are driving when an earthquake suddenly happens,just stay in your car until the shaking ends. However, if the footbridge falls and breaks your car,get out of it and sit or lie next to it. All the broken cars have voids 3 feet high next to it.

1. What should you do if you are in a building when an earthquake happens?

   A. Rush out quickly            B. Sit in the kitchen
