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.

A. has the longest wavelength among all the colors

C. doesn’t hit “raised area” in the atmosphere

D. cannot pass through space successfully

2.How long can’t the moon be seen during the daytime in a month?

A. 2 B. 28 C.30 D. 31

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.

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?

The first Earth Hour was held in 2007 in Sydney, Australia when 2.2 million individuals(个体) and more than two thousand businesses turned their lights off for one hour to take a stand against climate change. Only a year later Earth Hour had grown into a global event with more than 50 million people across 35 countries and territories（行政区）participating(参加). Global landmarks such as the Sydney Harbour Bridge, CN Tower in Toronto, Golden Gate Bridge in San Francisco, and Rome’s Colosseum, all stood in darkness, as symbols of hope for a cause that grows more urgent(紧急) by the hour. In March 2009, millions of people took part in the third Earth Hour. Over 4000 cities in 88 countries and territories have promised their official support for the event. On Saturday 27 March, Earth Hour 2010 became the biggest Earth Hour. A record said 128 countries and territories joined the global display of climate action.

The event is organized by the World Wide Fund for Nature, also known as the WWF. The organizers say climate change is one of the greatest threats(威胁) facing wildlife and nature. They also say when it comes to save energy and money, big changes start with small steps like turning out the lights. Now people are all joining together in a global effort to show that it’s possible to work on global warming. Earth Hour has brought about some new changes to our lives. People join in activities such as candle-lit dinners and star-gazing parties as a response to the call for "going dark".

This year , Earth Hour is asking people to take the next step and go beyond one hour. So if you haven’t done so, next year, late half past eight to half past nine, let us turn off the lights for one hour for the environment! Earth Hour is a call to stand up, to take responsibility(责任) and to get involved(与……有关) in working towards a better future. Earth Hour is a message of hope and a message of action.
