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 (照亮) 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

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?

 

Let’s face it: homework can be almost as frustrating (沮丧) for parents as it is for kids. Getting kids to do their homework can be a challenge, and when they do sit down to study, a lot of other problems can appear.

Doing homework may not be as fun as playing video games or chatting with friends, but it shouldn’t be something that kids hate. Your children’s assignments (任务) should help them build a skill or learn something new.

You can help by being a homework monitor, stepping in to answer questions or offer encouragement. This gives you a chance to see what they are learning and how well they understand the material. It helps you understand their learning style and shows you care about their education.

Many kids refuse to study by asking why they have to learn things they’ll never use in real life. If your son or daughter shows little interest in their assignments, you can make them seem more important by pointing out ways you use them in daily life.

If parents feel that their kids are overloaded (超负荷), they can talk about it with the teachers. If you think it takes your child too long to finish homework, try to make a decision whether the problem lies in having too much work or managing time poorly.

If your child complains of boredom while doing homework, give him or her the following suggestions:

Get help from friends: if your children are bored with an assignment, let them call a friend for help or invite a friend over to work on it with them.

Add physical activity: set mini-goals for homework and allow time for relaxing, jumping around, or a snack after each goal is completed. For a kid who can’t sit still, find active ways to study.

Turn the tables: let your children teach you a lesson. Let them give you a test on the things they have just learned.
