The world uses about a thousand million tons ...

The world uses about a thousand million (百万) tons of water a day. Water is a human right and everyone should have their share. Yet more than 700 million people around the world have trouble getting clean, safe water.

Treating wastewater is a good way to provide fresh water for us. And it also helps the environment by keeping waste out of rivers and oceans. 80% of wastewater around the world is not treated at all, and it is running into oceans. But now we have got the technology to treat and reuse the wastewater.

While 75% of our planet is covered with water, only about 2% is fresh water—that comes from rivers, lakes, ice and snow. The rest, 98% of the water, is in seas and oceans. It is too salty to drink. Then desalination businesses come in. More than 19,000 factories have been built around the world, mostly in coastal countries. They process (加工) more than 92 million tons of water every day. But the technology they use requires a lot of energy.

Scientists are working to create a less costly technology. They want to produce 20 times more clean water and make sure everyone has enough. But for now, the world still faces each day with not having enough water for everyone.

1.How many people have trouble in getting clean water around the world?

A. Under 10 million. B. Only 19 million.

C. About 92 million. D. Over 700 million.

2.Treating wastewater helps the environment by _____.

A. storing waste in ice and snow B. letting waste run into oceans

C. keeping waste out of rivers and oceans D. sending waste to coastal countries

3.What does the underlined word "desalination" in Paragraph 3 mean?

A. 远洋运输 B. 潮汐发电 C. 食盐销售 D. 海水淡化

4.At present, the technology to process water_____.

A. needs much energy B. saves much money

C. satisfies everyone D. causes pollution

5.What can we infer from the last paragraph?

A. Water should be a human right. B. The water problem is still serious.

We have been used to wearing masks(口罩)in public since February. About 300 million masks are used and then thrown away every day in China. Where do these masks go? You might think they just go in a rubbish bin. But that's just the first stop on the masks' journey.

After the masks are thrown into the bins, rubbish trucks empty the bins and take the rubbish to landfills(垃圾场). Next, the masks will be taken to rubbish incinerators(焚化炉)and burned. Burning masks might not seem to be very good for the environment. Won't it cause pollution?

The answer is "no", according to China Daily. The main material of most masks is polypropylene(聚丙烯). It's non-toxic(无毒的). After burning, it changes into water and CO2.

In fact, burning the masks can bring some benefits(益处). The process of burning the rubbish can produce electricity. Burning one ton of rubbish can produce more than 400 kilowatt hours(度)of electricity. Some people make a prediction that there will be 162,000 tons of used masks in China this year. Burning all of them can produce more than 64 million kilowatt hours of electricity. This is enough to make an electric car drive about 370 million km, which is 9,250 times as long as the earth's equator.

At last, the slag(残渣)from burning masks can be recycled to make bricks(砖块)or fill the roads.

1.How many masks are used and then thrown away every day in China?

A.More than 64 million. B.About 300 million. C.About 370 million. D.About 9,250 million.

2.The first stop on the masks' journey is ________.

A.electricity factories B.landfills C.rubbish trucks D.rubbish bins

3.The main material of most masks is________.

A.plastic B.polypropylene C.water D.CO2

4.Which of the following is TRUE according to the passage?

A.Burning masks won't cause pollution.

B.People are not used to wearing masks in public.

C.There are 162,000 tons of used masks every month in China.

D.The process of burning the masks can produce electricity and bricks.

5.What is the best title of the passage?

A.How do We Burn Used Masks? B.How do People Produce Electricity?

C.Where do the Used Masks Go? D.Why do We Throw Away Used Masks?

水上公园

I love going to water parks for fun. However, many people think that water parks are bad for the environment. 1.

There is not too much drinking water in many parts of the world, so people think water shouldn't be used just for fun. 2. And there are nearly 2, 000 water parks around the world, so that's a lot of water!

Some indoor water parks are able to recycle as much as 97 percent of the water they use.4. Building attractions in the shade will result in less water being lost. So new designs are being created in order to keep water in the pools and prevent it from being wasted.

5. So they are not going to disappear very soon.

If you think water is wasted at water parks, think about how much more water you have wasted so far! In that case, you could argue that water parks actually help save water.

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.
