There are seven continents﹙洲﹚in the world. Among them, Antarctica﹙南极洲﹚is the most special one. It is a world of snow and ice all year round. China has sent many scientists there. They try to find resources﹙资源﹚under the icy land and study climate change and sea biology.

What do they eat?

Scientists don’t have many choices on what they eat. About 60% their food is frozen food. It is easy to heat﹙加热﹚。Meat is common on the menu, while vegetables are not usual. Fresh vegetables are hard to grow in the cold weather. Therefore, people often eat dried and canned vegetables.

How do they sleep?

In Antarctica, summer lasts from November to March. During this time, Antarctica faces the sun and gets sunlight 24 hours of the day. In order to get some sleep,scientists cover the window with black cloth to make “night”.

How do they work?

People can wear warm clothes to be against the cold weather, but they can do little with the strong wind. Sometimes, the wind is even stronger than a typhoon. It can easily blow people away.

So there are ropes﹙绳索﹚that connect some research stations. People can hold these ropes to keep balance in strong winds.

How do they keep in touch with others?

There are no cables or Internet on the frozen continent. So mobiles and computers don’t work there. Scientists usually use two-way radios to communicate at work. If they want to say hello to family and friends, they can use the satellite phones.

Mobile phone has become a problem for high schools. Some high-school students in Australia are not allowed to carry mobile phones during school hours.

Mobile phone used among children has become a problem for the school years. Several children have got mobile phones as Christmas presents, and more students will want them.

She said some schools had tried to ban(禁止) mobile phones. Some parents felt unhappy because they couldn’t get in touch with their children.

Many teachers said students should not have mobile phones at school. But there was a good reason that they could leave their phones at school offices. They also said they were easily lost and were a distraction for studies.

There is not enough oil in the world now. As time goes by ,it becomes less and less ,so what are we going to do when it runs out? Perhaps we will go back to use horses ,carriages and bicycles .

 In the Second World War ,some people didn＇t use gas made from petroleum （石油）in their cars .They made gas from wood and plants instead . The cars didn＇t go fast ,but they ran ,so this was better than nothing. However, in the future, we can＇t cut down all our trees to make gas; we need our trees for other things, too.

Besides different types of gas, we can also use electricity(电)to run our cars but first we must make the electricity ！Some countries have coal and they make electricity with that, but we might not always have coal, either. Other countries have big ,strong rivers and they can use the power of water to turn turbines(涡轮机) and make electricity more easily and cheaply.

We are also able to get power from the ocean tides. We put turbines into the mouth of the river .Then the tide comes in ,the water turns the turbines and then it goes out ,it turns them again.

Which of these ways will be used to run our cars in the future?

1.When might people have to go back to using horses and carriages?

A. When they are poor    

B. When they run out of oil

C. When they need more exercise

D. When there aren＇t any big trees in the world
