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 |
A.2 | B.28 | C.30 | D.31 |
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. |
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。

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.

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.

“Eat breakfast like a king, lunch like a prince and dinner like a pauper(穷人).” the old saying tells us, breakfast is the most important meal of the day. It us with energy after a long night without food.
If people don’t have breakfast in the morning, they will feel tired and get angry . Breakfast helps stay more focused in school. A study showed that children who eat breakfast regularly score in most subjects.
Breakfast is also important for weight loss. If you have a balanced breakfast, you will eat less throughout the day.
A healthy and breakfast should include some protein(蛋白质) like eggs, milk or a little meat, which makes you all day. Carbohydrates(碳水化合物) like rice or bread keep you active. Vegetables and fruit have the vitamins humans need.
, in China, breakfast is different from region to region. Porridge pickles(腌菜),baozi, noodles, soybean milk and youtiao are common throughout the country. Although western culture has influenced China a lot, most people still traditional Chinese breakfast. They think that porridge and noodles are not only easily digested, but also can provide enough in the morning

Stress isn’t always bad. Sometimes, people’s stress is important during emergency situation, such as when a driver has to stop his car to avoid an accident. Sometimes, stress can help people do their best, like while getting ready before a big competition or exam.
However, too much or long-term stress gives people a stress overload. People with stress overloads may have problems remembering or concentrating on things. They are quick to get angry or lose patience. They may even have other problems, such as sleeping problems, headache and often getting colds.
What are some ways to deal with stress?
Ask for help.
Everyone has stress. For many people, stress is so common that it has become a way of life. Don’t be too shy to tell your parents or teachers that you are having a hard time. They may comfort you or give you some useful advice. Sometimes just sharing your problems with someone else can make you feel better.
Solve the little problems.
Develop skills to calmly look at a problem, choose a way to solve it and take action. Solving the little problems successfully helps to build confidence to move on life’s bigger ones.
Learn to relax.
Activities that make people clam and happy can help manage stress. For example, reading a good book, enjoying music, spending time with your parents, getting a good night’s sleep, or just taking a relaxing bath are all good ways to reduce your stress..
Encourage yourself with positive words.
When you are under your stress, saying certain things to yourself may help you feel more confident. For example, you might tell yourself, “I will do the best that I can.” or “I can handle this if I take it one step at a time.”
