Question

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?

Answer 1

【小題1】D
【小題2】B
【小題3】B
【小題4】C

解析試題分析: 本文是在講許多父母害怕被孩子問到一些科學(xué)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(xì)節(jié)理解題。根據(jù)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(dāng)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(lán)色不波長短，被分開。所以選D項。
【小題2】B 細(xì)節(jié)理解題。根據(jù)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(xì)節(jié)理解題。根據(jù)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(zhuǎn)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(xì)節(jié)理解題。根據(jù)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。
