No matter who we are, where we are, or what we do, we cannot live without water. It is the source(源泉)of all life and we need it every day. But in truth we’re facing serious water problems.
Although water covers 71 percent of earth’s surface, we can only use a very small amount of it. Only about 3 percent of the world’s water is fresh water. It comes from lakes, rivers and underground. Today, there are over 663 million people living without a safe water supply close to home, according to the United Nations.
To remind people of the importance of water, the UN first set World Water Day in 1993. It is held on March 22 each year.
Instead of letting it pollute the environment, the industries need to treat it first. People from different countries have their own tips for saving water and reusing wastewater.
·Turn off the water while brushing.
South Africa is one of the world’s driest countries. The website gives some tips on how to save water in the bathroom. Turn off the water while brushing your teeth and save 1,000 liters a month.· ▲ Collecting rainwater is an important way to save water in Germany. Most houses built in the last few years have rainwater collection systems. If you don’t have the device, just put a bucket(桶)under your roof when it rains. Keep the grass longer. Most Australians have a grass lawn around their home. Nature Conservancy Australia says it is best to keep the grass longer. That way the grass covers the soil and reduces water evaporation (蒸发).
China takes action to deal with water problems too. 作为学生,我们也应该尽我们所能来与水资源浪费问题作斗争。 Let’s move!

One possible version:
As we all know, the environment around us is getting worse and worse.
In some places, we can't see fish swimming around in the rivers or trees on the hills. Some people even have no clean water to drink. So I think something must be done to protect our environment. For example, we can go to school on foot or by bike. We can use shopping baskets instead of plastic bags when shopping. And in our daily life, we should use both sides of paper.
If we do small things like these, there will be less pollution and our life will be better. Let's work together to make our earth more beautiful!Unit 13 We’re trying to save the earth!

The earth is about 4,600 million years old. Modern man has lived on the earth for only 35,000 years, but during that time, we have changed our planet in many ways. Many of the things that we have done are good, but more are not good for the earth.

No matter who we are, where we are, or what we do, we cannot live without water. It is the source(源泉)of all life and we need it every day. But in truth we’re facing serious water problems.
Although water covers 71 percent of earth’s surface, we can only use a very small amount of it. Only about 3 percent of the world’s water is fresh water. It comes from lakes, rivers and underground. Today, there are over 663 million people living without a safe water supply close to home, according to the United Nations.
To remind people of the importance of water, the UN first set World Water Day in 1993. It is held on March 22 each year.
Instead of letting it pollute the environment, the industries need to treat it first. People from different countries have their own tips for saving water and reusing wastewater.
·Turn off the water while brushing.
South Africa is one of the world’s driest countries. The website gives some tips on how to save water in the bathroom. Turn off the water while brushing your teeth and save 1,000 liters a month.· ▲ Collecting rainwater is an important way to save water in Germany. Most houses built in the last few years have rainwater collection systems. If you don’t have the device, just put a bucket(桶)under your roof when it rains. Keep the grass longer. Most Australians have a grass lawn around their home. Nature Conservancy Australia says it is best to keep the grass longer. That way the grass covers the soil and reduces water evaporation (蒸发).
China takes action to deal with water problems too. 作为学生,我们也应该尽我们所能来与水资源浪费问题作斗争。 Let’s move!
