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?

小题1:D
小题2:B
小题3:B
小题4:C

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。

There were smiling children all the way. Clearly they knew at what time the train passed their homes and they made it their business to stand along the railway, wave to complete strangers and cheer them up as they rushed towards Penang. Often whole families stood outside their homes and waved and smiled as if those on the trains were their favorite relatives. This is the simple village people of Malaysia. I was moved*.
I had always traveled to Malaysia by plane or car, so this was the first time I was on a train. I did not enjoy the long train journey and had brought along many magazines to read and reread. I looked about the train. There was not one familiar face. I sat down and started to read magazines.
It was not long before the train was across the Causeway and in Malaysia. Johore Baru was just a city like Singapore, so I was tired of looking at the crowds of people as they hurried past. As we went beyond* the city, I watched the straight rows of rubber trees and miles and miles of green. Then the first village came into sight. Immediately I came alive, I decided to wave back.
From then on my journey became interesting. I threw my magazines into the waste basket and decided to join in Malaysian life. Then everything came alive. The mountains seemed to speak to me. Even the trees were smiling. I stared at everything as if I was looking at it for the first time.
The day passed fast and I even forgot to have my lunch until I felt hungry. I looked at my watch and was surprised that it was 3:00 pm. Soon the train pulled up at Butterworth. When my uncle arrived, I threw my arms around him to give him a warm hug. I had never done this before. He seemed surprised and then his face warmed up with a huge smile. We walked arm in arm to his car.
I looked forward to the return journey.

Stress is a normal physical response to things that make people feel worried or break their balance of life in some way.
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.”

Mary picked up a pencil and a piece of paper,saying,“Now,you want to earn money for the autumn camping trip,right?” Tom,her brother,nodded.He wasn’t able to go last year because he hadn’t earned enough money during the summer.This year he came up with a plan.
He made a necklace for his mother that everyone admired.They were surprised to learn that Tom had made it for her.Why not make more necklaces and sell them?
“OK,” said Mary,“The first thing you need to do is to figure out(计算)how much you have now.’’
“I have $20.00 in the bank,and $7.25 in my room,” explained Tom.
“That gives you a total of $27.25,” said Mary,“That is called your capital.The next thing you need to know is how much it will cost you to make each necklace.”
“Well,the pet shop will give me all the feathers the birds lose.I'll have to buy the beads(小珠子)and string,” said Tom.
Mary wrote on the piece of paper:
CAPITAL      $27.25
EXPENSES     Feathers                       no cost
String for 10 necklaces        $  2.50
Beads for 10 necklaces   +    $ 15.00
Total                        $ 17.50
“How much do you think you can sell such a necklace for?” asked Mary.
“Hmm,” Tom looked thoughtful and said,“There's a shop in town that sells almost the same kind of necklace for $ 7.50.If I charge(要价)$ 6.00,people will think that's a bargain.”
“OK.If you sell each necklace for $ 6.00,you'll make a good profit(利润)on each then,” said Mary.
“Hurray!” Tom cried,“If I sell 20 necklaces,I'll have enough from the profit for the camping trip and $10.00 left over.”
