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.

1.The sky looks blue mainly because the color blue in the sunlight_______.

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

D. cannot pass through space successfully

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?

 

In my life, I have received many gifts from my mother. The most important was my life. However, there’s another special gift I will never forget.
When I grew up, I left home and got a job in South America. One day , a call came from my brother, “Something is wrong with Mom. She’s forgetful (健忘). She thinks we’re hiding (藏) you from her…”
I got back home at once. It was clear that she would not be able to stay in the house alone.
For nearly 4 years I stayed with my mother and we had fun. We even planted some vegetables together in the garden. It was not easy for me. I had to stop working. When I had to leave , I had to ask someone to look after her or drive her to my brother’s.
When it became clear that she was near the end, family memebers were called to come to say their good byes. For 3 weeks my sister and I just sat with Mom, took long walks and spent some real time with each other. My sister and I were both with Mom when she was passing away (去世), holding her hands and telling her how much we loved her. At the end of life, my mother gave me the gift of time with my sister in a way we would never have given ourselves.

Last week, 169 Junior 1 students at No. 35 Middle School of Shenyang took their first no-teacher exam. After the teacher handed out the exam paper, he left the room and never came back. A student collected in the papers when the exam ended.

“That test was not only a test of knowledge, but also a test of moral(道德). We wanted to show students how important honesty is, ”said Cai Wenguo, the school’s headmaster. The school says no cheating (作弊)happened in the test. Next year, it wants 80％ of its exams to be without teachers. But students have different ideas.

“I was happy and excited during the exam because my teachers trusted me, ”said Lang Yudan, a 13-year-old girl in Class 11.

“Schools must trust students a lot not to use invigilators（监考人）. But I think it is too early. Some students will cheat if there are no invigilators. And the students will not be able to ask for help when needed. ”said Hua Sha.

“I don’t like having invigilators in exams. When they walk around the classroom, they make me nervous. I would get higher marks without them in the room because I would feel more relaxed. ”Liu Qingxi said.

And they can also keep the classroom in order when something unusual happens. They may make me nervous, but I still think we need them. ” Shangguan Yuan said.

Not using invigilators may be a good idea. But before using it, schools must tell students the importance of honesty and try to find ways to solve something unusual in exams.
