Nearly all our food comes from the soil（土地）. Some of us eat meat, of course, but animals live on plants. If there were no plants, we would have no animals and no meat. So the soil is very necessary for life. The top of the ground is usually covered with grass or other plants. There may be dead leaves and dead plants on the grass. The waste matter（糞）from animals also falls on it.
All soil needs food. If we do not give it any, the plants will be weak. Farmers found that animals’ waste is the best food for the soil, but chemical fertilizers（化肥）are also very useful. The same crop（莊稼）should not be grown in the same place every year, it’s better to have a different crop. A change of crop and the use of a good fertilizer will keep the land good.
【小題1】Which of the following is true?

A．All our food comes from the soil.

You may know about “ junk food” like French fries. But do you know about “junk sleep”?
Recently, a British survey found that electronic(電子) products in teenagers bedrooms are affecting(影響)their sleep.
The survey was done among 1,000 British kids from 12 to 16. It found that thirty percent of them got just 4 to 7 hours sleep every day. But doctors say they need 8 to 9 hours.

閱讀下面的短文．并根據(jù)短文后的要求答題。

Since 1850．the temperature of Earth’s surface has increased about 0.6°C．Scientists predict it may warm much more by the end of this century．Who’s turning up the heat? Well, it seems that we are! Some of this global warming may be natural．However，nearly all scientists now agree that most of it is due to peoples actions．Over the past 150 years, we've added huge amounts of certain gases, especially carbon dioxide（CO2）to the air．These gases can keep heat near Earth's surface，so more carbon dioxide means more heat is kept near Earth's surface．Global warming may change the weather in ways that lead to more severe storms，floods and droughts．

We add carbon dioxide to the air when we burn things, especially fossil fuels．Fossil fuels are energy sources formed from the remains of plants and animals that lived millions of years ago．Coal，oil，and natural gas are all fossil fuels．People in the United States and other countries started bunting large amounts of fossil fuels more than a century ago．The amount d fossil fuels being burned each year has been increasing worldwide．The more we burn，_____________________．

What can we do to help? Nowadays to live a low-carbon life is quite popular in the world． Low-carbon means to reduce the amount of carbon dioxide．Saving energy and reusing are the key words. In fact, even the simplest everyday activities can make our lives low-carbon．

1．What problem can global warming cause?（根據(jù)短文內(nèi)容回答問題）

2．What are fossil fuels?（同上）
