“Homestay is a form of study abroad program. It allows the visitor to rent a room from a local(当地的) family to better understand the local lifestyle. It also helps to improve the visitor’s language ability,” said a teacher during a school meeting last term.” Students who wish to learn more about foreign cultures or to get foreign experience should join this kind of holiday. I am sure you won’t be disappointed(失望的).”

After this special meeting, I always thought about this kind of holiday. Last month, I had a chance at last to go on such a holiday with some of my schoolmates and we went to London, a place where I had wanted to go since years ago.

As we were still young, we had a group leader who planned things for us and looked after us. After we got to London, we went to stay with different families. I was lucky that my host family(寄宿家庭) was a white couple who had a daughter about my age. They treated me as a daughter of their family during my stay there. They were interested in me and I learnt a lot of things from them, too.

The holiday was filled with activities every day. After breakfast, a local teacher would come to take us in his car. Then we would have classes or go on a sight-seeing trip to different places of interest like the Big Ben, the London Bridge, and the Buckingham Palace. We would go back to our own homes after the activities.

The holiday was a valuable experience for me. I enjoyed every minute of it. Yet, time really flew fast. Three weeks later, we had to leave “home” for Hong Kong.

On April 9，2010，a solar-powered plane successfully made its first flight．It flew at a speed of 70 km/h at a height of 1，200 meters in the sky above Switzerland for 87 minutes．It is the first solar-powered plane in the world．A group of engineers，led by Bertrand Piccard，a well-known pilot，made this plane．

The solar-powered plane is different from the planes that we usually see．The' plane has a thin body with two very big wings full of solar cells．It uses sunlight as its energy, but it was not easy to make such a plane．First of all，Bertrand Piccard and his group members had to find out how to get energy from the sun．They used 12，000 solar cells to catch the sunlight．Then they had to find a good way to store it．They used special batteries to store the energy．What's more，the plane should be light enough so that it would not use too much power．It should also be strong enough to hold its body to fly in the sky．They used the strongest and lightest materials" to build the plane．It weighed 1，600 kg and only needed the power of a small car．

After this successful flight，Bertrand Piccard said，"The airplane has landed but we have not yet landed．"Their next step is to have a non-stop flight around the world by 2013．Before they can do that，they will have to work out how the plane can store enough energy during the day and keep flying at night．Also，the team will have to watch the weather closely to make sure the plane can fly．

1．How long did the solar-powered plane fly in the sky on April 9，2010?

A．9 minutes．                                            B．70 minutes．

C．87 minutes．                                          D．1，200 minutes．

2．Where is the energy of the solar-powered plane from?

A．The sun．                  B．Air．              C．The moon．      D．Wind．

3．The first solar-powered plane weighed _______

A．1，200 kg                                            B．1，600 kg

C．12，000 kg                                                 D．16，000 kg

4．When can the solar-powered plane take a non-stop flight around the world?

A．When it is light enough to fly in the sky．

B．When it is strong enough to hold its body to fly in the sky．

C．When it looks different from the planes that we usually see．

D．When it can store enough energy during the day and keep flying at night．

　　Children have their own rules in playing games. They seldom need a referee（裁判）and rarely trouble to keep scores. They don't care much about who wins or loses, and it doesn't seem to worry them if the game is not finished. Yet, they like games that depend a lot on luck, so that their personal abilities cannot be directly compared.
