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

小題1:D
小題2:B
小題3:B
小題4:C

試題分析: 本文是在講許多父母害怕被孩子問到一些科學問題,下方列舉一些父母所不知道的問題,你可以問問你的父母知道嗎?
小題1:D 細節理解題。根據第三段提到的While it moves in a straight line when going through space, it starts to divide as it hits “raised area” in the atmosphere當他穿過太空時,被分開,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.其它的顏色可以穿過太空而藍色不波長短,被分開。所以選D項。
小題2:B 細節理解題。根據第五段提到The only time it is not able to be seen during its 28-day orbit (軌道) around the earth is when it is right between the earth and the sun在其28天軌道(軌道)在地球是地球和太陽之間這時候恰好是我們是看不到的,所以28天是看不到的。所以選B項。
小題3:B 細節理解題。根據最后一段提到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他們會聚集在蜂巢轉成一個球以蜂后為中心,這樣讓他們保暖以過冬。所以選B項。
小題4:C 細節理解題。根據文中提到Q: Why is the sky blue? Q:Why does the moon sometimes appear during the daytime? Q: Where do birds/ honeybees go in winter?這三個問題,所以沒有提到C項。

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.
小題1:The writer expected the train trip to be ______.
A.dangerousB.pleasant C.excitingD.boring
小題2: What impressed the writer most during her train trip?
A.The friendly country people
B.The mountains along the way.

小題3:Which of the following statement is TRUE according to the passage?.
A.The people on the train were the villagers’ favorite relatives.
B.The writer spent the whole journey reading magazines.
C.The writer thought he enjoyed the train journey at last.
D.The writer’s uncle gave him a warm hug with a huge smile.
小題4: What's the best title of the passage?

Dear Ace Travel,
My family and I want to take a trip this summer somewhere in eastern China. I hope you can provide me with some   about the kinds of vocations that your firm can offer. We would like to travel to an    place and we don’t mind how far we have to go. It has to be a place where we can do lots of     activities; we especially love hiking and swimming, but any kind of outdoor activity is fine. We also need to stay in an    hotel or apartment. It would be nice if we could get a room with a kitchen so we could save money by cooking our own meals. The room needs to be  for three people. Also, we’d like to stay at a place with a big pool or somewhere near the ocean. Could you please give me some suggestions for vacation spots?
Thank you very much!
