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

Sometimes people say that they see strange flying objects (物体) high up in the sky. People call these strange objects “Unidentified Flying Objects (UFOs)”.
Dennis Bardens wrote an article. In it, he told us that he once saw a UFO himself. He had dinner one night with a friend near Tripoli, Libya. After dinner Dennis with his friend walked across a yard (院子) to his room. He noticed that the “moon” looked strange that night. But it wasn’t the moon. He saw the object’s light was moving. It seemed to be an object like a big plate. In some ways it looked like smoke with light on it. But it wasn’t smoke because it didn’t change its shape (形状). When the object was nearer, he noticed that its bottom (底部的) part was brighter than the top. The bottom part was yellow and the top was red. Then the object suddenly turned away and left, moving very fast.
On a later day, Dennis talked to other people about it, and he found some people also saw it. They all described (描述) it in the same way.

A recent survey of 2000 parents in Britain showed that they are often afraid of science questions asked by their curious children only because they have no idea what the answer is. Here is a list of some simple questions that you can ask your parents to see if they know the answers.

    Q: Why is the sky blue?

    A: You probably know white sunlight is made up of seven colors. While it moves in a straight line when going through space, it starts to divide as it hits “raised area” in the atmosphere. The ones with longest wavelengths pass through easily. The blue , however , can be taken in by the gas molecules (分子) because it has a shorter wavelength , which in turn scatters (使分散) it in different directions. That’s why when you look up at the sky, it appears to be blue.

    Q:Why does the moon sometimes appear during the daytime?

    A: The simple answer to that is because just like any other object it is being lit by the sun. As long as it is around 45 degrees or even 90 degrees off the sun, it will receive light and be able to be seen. The only time it is not able to be seen during its 28-day orbit (轨道) around the earth is when it is right between the earth and the sun. That’s because its back , which is not lit by the sun, is facing us.

    Q: Where do birds/ honeybees go in winter?

    A: While the bird part is quite easy, since a lot of them get together and travel, the honeybee part is likely to puzzle your parents. It turns out that these busy insects stop being that active when the temperature drops below 50°F. Instead ,they get together in the lower central area of the hive （蜂巢）and form a ball around their queen. This helps keep both warm enough to survive the cold winter months.

A. has the longest wavelength among all the colors

B. cannot be taken in by the gas molecules

C. doesn’t hit “raised area” in the atmosphere

2.How long can’t the moon be seen during the daytime in a month?

A. 2                             B. 28                           C.30                                      D. 31

3.What do honeybees choose to do when the temperature drops below 50°F?

A. They choose to be active in the wild.

B. They choose to keep themselves warm.

C. They choose to travel to a warm place.

D. They choose to get together in the upper central area of the hive.

4.What is NOT explained in the passage?

A. Why is the sky blue?

B. Why is the moon able to be seen during the daytime?

C. Why do birds travel in winter?

D. Where do honeybees go in winter?

The widespread number of food scandals ( 丑闻) in China is making many people pause before they put their chopsticks in their mouth. They are wondering if the food they are eating is clean, healthy and nutritious or does it contain something harmful that will cause disease?
Most of the food we eat today is processed food( 加工食品). That means the foods we buy in stores and supermarkets, especially packaged foods, are prepared in factories. Chemicals are added to the foods in these factories to make them look better, taste better and last longer on the shelf. The chemicals are supposed to be harmless and there are laws that regulate which chemicals can and cannot be used. Unfortunately, some producers do not obey the laws.
A producer of steamed buns (馒头) in Zhejiang Province was recently discovered to be breaking the law. He was adding yellow dye and other banned chemicals to the buns. He was also taking old buns and using them to make new buns. Most of the buns were sold to schools and eaten by students. . . like you’
Why did he do it? Why did he break the law and endanger people’s health? The answer is simple: he wanted to make more money. It was a moral failing, and this is at the heart of the food scandals in China. Too many people focus on making money and not on the effects their actions can have on others.
