【题目】 We all do it. We all need it. Most of us need to do it for seven to nine hours a night. It is of course sleep. Many scientists believe the truth. An adult should get eight hours sleep every night. However, some people can live without feeling sleepy after as little as six hours of sleep. But other people need about ten hours a night. Babies usually sleep between 14 to 17 hours a day. Usually they only stay awake for one to three hours.

Do you take a nap (打盹) in the day? Some adults and children need to nap. This just depends on the person. One thing scientists have learned is that man is the only mammal (哺乳动 ) that stops himself from going to sleep. This can be bad for our bodies in many ways. Scientists believe not sleeping enough can make us eat more. And not sleeping enough can make us put on weight. Hopefully you are a good sleeper and get a good night’s rest tonight!

【题目】 I've always been very interested in the beauty of China’s culture and history. So when one of my friends moved to Beijing from the UK.It was the perfect excuse to visit.

My friend Tony and I had expected a big city filled with buildings and busy streets. But when we arrived,we were surprised.

The first thing that surprised us was the space. Beijing is really huge.Its wide streets and green spaces made every area feel less crowded(拥挤的).Everywhere we looked,there were people cleaning and tidying.It really gave off national pride.

We were worried that few people would speak English in Beijing.But we found that it was common for Chinese people to know a few words of English.and many knew much more.

But the most exciting part of our visit was riding around in the sunshine on bicycles—we felt very Chinese as we travelled around the city on shared bikes.

It was great to experience Beijing in person. This was my first visit to China. but certainly not my last.

【题目】 Recently, China announced it had achieved success in drilling fire ice or methane hydrate(天然气水合物,即可燃冰), from the seabed in the Shenhu area of the South China Sea. It produces high amount of energy when it is burned, leaving nothing but dioxide and water.

Many countries, including the United States and Japan, have long been doing research on methane hydrate, but taking it from bottom of the sea has been a common problem they are facing. According to reports, China succeeded in drilling methane hydrate for a number of days continuously and got an average of over 16,000 m daily. It is believed to be a big breakthrough.

Scientists say there is about 21,000 trillion (万亿 ) m of methane hydrate in the world. If we can use it, it can meet the world's energy need for 1,000 years. However, it is too early to say a new energy source (来源 ) has been found because we are still facing two main challenges ——environmental risk and economic (经济的) cost. When methane hydrate is taken from the seabed, it may go into the air easily. That's very bad for the environment because methane is one of the worst greenhouse gases. Besides, drilling methane hydrate is very expensive as well.

However, China's technology breakthrough is very important because it shows the way researchers across the world should take. It also raises hopes that one day we can drill methane hydrate as a source of energy.

B.China is making good use of fire ice throughout the country.

A.How to take it out from the bottom of the sea.

B.How to turn it into useful energy at the lowest cost.

C.How to make it cheap on the future energy market.

D.How to change it into a traditional form of energy.

3Why is it too early to say a new energy source has been found?

A.Because it's too difficult to find the place where the fire ice lies and how to drill it.

B.Because it's not easy for fire ice to go into the air and be good for the environment.

C.Because it’s quite impossible for fire ice to take the place of other sources of energy.

D.Because it's expensive to drill fire ice and it may do great harm to the environment.

4Where can we probably read the article?

A.In a storybook.B.In a newspaper.
