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.
小题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
小题2:How long can’t the moon be seen during the daytime in a month?
A.2 B.28 C.30 D.31
小题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.
小题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?

答案

小题1:D
小题2:B
小题3:B
小题4:C
解析

试题分析: 本文是在讲许多父母害怕被孩子问到一些科学问题,下方列举一些父母所不知道的问题,你可以问问你的父母知道吗?
小题1:D 细节理解题。根据第三段提到的While it moves in a straight line when going through space, it starts to divide as it hits “raised area” in the atmosphere当他穿过太空时,被分开,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.其它的颜色可以穿过太空而蓝色不波长短,被分开。所以选D项。
小题2:B 细节理解题。根据第五段提到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在其28天轨道(轨道)在地球是地球和太阳之间这时候恰好是我们是看不到的,所以28天是看不到的。所以选B项。
小题3:B 细节理解题。根据最后一段提到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他们会聚集在蜂巢转成一个球以蜂后为中心,这样让他们保暖以过冬。所以选B项。
小题4:C 细节理解题。根据文中提到Q: Why is the sky blue? Q:Why does the moon sometimes appear during the daytime? Q: Where do birds/ honeybees go in winter?这三个问题,所以没有提到C项。
举一反三
March 5 is “Lei Feng Day”. Fifty years ago on this day, Chairman Mao Zedong called on people to “learn from Lei Feng”. Now half a century has passed. Is the spirit of Lei Feng outdated? Some people have shown us that it’s not. But people have also changed the ways in which they help others.
Li Yulin, who works in a hospital in Hang Zhou, Zhejiang, has been a volunteer for 15 years. He still remembers his experience in an old people’s home several years ago. An old woman held his hand and said, “You don’t need to do anything for us. Seeing young people like you here is all we need.” Those words made Li think: in what ways can we help people better? “Every person does what they can, no matter how small it is, to give out positive energy. And before we lend a helping hand, we should find out what they want,” Li said to the Qianjiang Evening News.
As well as Li, other people have shown their understanding of the spirit of Lei Feng. A “noodle fever” swept Zhengzhou, Henan in January. It started with an online post. Li Gang, a 42-year-old local man, said in the post that he has got cancer. He needed a lot of money for an operation. He was not asking for donations, but hoped people would come to eat at his restaurant. Li’s post spread quickly. Soon his restaurant was filled with people every day. Li had an operation on Feb. 2 and now he is getting better.
“It is good to help Li and his family like this for it shows them respect and doesn’t hurt their pride,” Qianjiang Evening News said.
