When we think about the deserts of the world,...

When we think about the deserts of the world, water abundance(资源丰富)is one of the last things that come to mind. But that might change for the Taklamakan Desert (塔克拉玛干沙漠) in China.

There is a huge underground sea that has more water than all of the great lakes in total in North America. "People have never dared to imagine so much water under the sand before, "said Professor Li Yan.

A basin is, a valley (山谷）that usually collects water from the mountain drainage systems(山脉排水系统), like water that has melted and is running down from nearby, snow-covered mountains. But, if you look at the Tarim (塔里木)basin, you won't see any water.

That's partly because local people collect most of the melt water to irrigate crops. The rest either seeps into the ground or evaporates into the dry desert air.

So how did this desert have such huge water? It dates back to (追溯到)2,000 years ago when farmers in the region began irrigating the land. And the soil of the local farmlands is salty, like the sea. "As a result, agricultural development over human history has enhanced the carbon sink," they write in their report.

They estimate(估计)that as much as 10 times the amount in all of the great lakes could be down there. The scientists don't advise locals to go digging for it, though, because it's extremely salty sea water.

1.Where does the story happen __________________.

A.China. B.Japan. C.North America D.Africa

2.What did they discover in Taklamakan Desert?

A.Oil. B.Air. C.Water. D.Plants.

3.What does the underlined word "basin" in Chinese in Paragraph 3?

A.盆地 B.脸盆 C.基建 D.水域

4.Why do the scientists advise locals not to dig for the water?

A.Because it's a dirty sea. B.Because it's salty.

C.Because it's not huge enough. D.Because they think it's bad for the desert.

5.What does the passage mainly write about?

A.The Taklamakan Desert. B.The Tarim basin.

C.Water abundance in China. D.A huge underground sea in Taklamakan Desert.

We all know that we need water to live. Up to 75% of our bodies is water and we need to drink water every day to be healthy! So what will happen to the Earth’s water if global warming （全球变暖）gets worse?

About 71% of the Earth’s surface is covered with water. When the temperature of the Earth rises, the temperature of the water rises, too. Higher water temperatures will kill the underwater plants and tiny fish. But it’s not just the fish! Higher temperatures also have an influence on animals on land. Some scientists think that because of global warming, two thirds of the world’s polar bears will never be seen on our planet by 2050.

Global warming makes the weather change, too. In some places, there will be less rain. This will cause deserts to be larger. In other places, the rain will become very strong and heavy, so we will have less farmland and not enough food for humans.

Global warming is a big problem. But we can help by making small changes like turning off the water, lights, and TV when we aren’t using them!

It seems that every day we read about at least one of these (earthquakes, floods and hurricanes) somewhere in the world.　 1.It's something much smaller and not so well­known as an earthquake—it's an insect called the locust.

The locust usually does things alone. It lives on its own and eats on its own.2. When the number of locusts increases somewhere and there are lots of plants to eat, the locusts get together in swarms.

3.It is found in Africa, the Middle East, and Asia—in about 60 countries altogether. When desert locusts swarm, they bring problems to one­tenth of all the humans in the world.

4.A swarm of desert locusts can be 1,200 km2 in size. And there can be 50 million locusts in each square kilometer. Each locust eats its own weight in plants every day—so a swarm of desert locusts can eat more than 150 million kilos of food in one day. They can also fly very long distances.5.

Farmers fear the desert locust because it destroys the harvest and brings hunger to people all over the world.

Americans buy more bottled water than any other nation in the world. 29 billion bottles of water are drunk each year. It takes 17 million barrels of oil to make these bottles. That's enough oil to keep a million cars going for twelve months.

So why don't more people drink water from the tap in the kitchen? Some people drink bottled water because they think it is better for them than water out of the tap, but that's not true. In the United States, the government makes sure water from the tap is safe.

People love bottled water because it is convenient to take with them. But maybe if they understand the problems it makes, they will try drinking from a glass at home or carrying water in a reusable bottle instead of a plastic one. Although plastic water bottles can be turned into some other useful things, only a small number of them are reused. The rest are taken away in rubbish trucks, or even worse, they end up as rubbish on the land and in rivers, lakes, and the ocean. Plastic bottles take hundreds of years to break down.

Water is good for you, so keep drinking it. But think about how often you use plastic water bottles, and see if you can make a change. If you take one to school, don't throw it away — bring it home and put tap water in it for the next day.

1.Americans buy the most bottled water in the world.

2.The United Nations makes sure water out of the tap is safe.

3.Plastic water bottles we use cause serious pollution.

4.It takes a hundred years to make plastic water bottles break down.

5.We should use a plastic water bottle as many as possible before throwing it away.
