Pre-reading
Fast reading:Put the following paragraphs in order.
( ) The sea seems to have the best answer. There is plenty of water in the sea. But we need to take the salt away from the sea water. This is very expensive. If scientists can find cheaper ways to do it, we can solve the problem of the shortage of water.
( ) How can we avoid a serious water shortage First, we should save water and not waste it. Second, we should protect our water resources and not pollute them. Third, we should discover ways to reuse water. Scientists have made some progress in this field. Today, some large cities are reusing their water. But people’s need for water is increasing day by day. We still don’t have enough water. What else can we do
( ) Although the world is hungry, it is even thirstier. While nearly of the earth is covered with water, we are still short of drinking water. This is because about 97% of the water on the earth is sea water. So we can’t use it for watering plants or drinking directly. Humans can only drink and use fresh water from places including rivers, lakes and underground.

Pre-reading
Fast reading:Put the following paragraphs in order.
( ) The sea seems to have the best answer. There is plenty of water in the sea. But we need to take the salt away from the sea water. This is very expensive. If scientists can find cheaper ways to do it, we can solve the problem of the shortage of water.
( ) How can we avoid a serious water shortage First, we should save water and not waste it. Second, we should protect our water resources and not pollute them. Third, we should discover ways to reuse water. Scientists have made some progress in this field. Today, some large cities are reusing their water. But people’s need for water is increasing day by day. We still don’t have enough water. What else can we do
( ) Although the world is hungry, it is even thirstier. While nearly of the earth is covered with water, we are still short of drinking water. This is because about 97% of the water on the earth is sea water. So we can’t use it for watering plants or drinking directly. Humans can only drink and use fresh water from places including rivers, lakes and underground.

My dear friends,
Water is very important to human beings. Let’s do something to protect and save it.
First, we should protect our water resources and not pollute them. The government should also pass laws against the water pollution. Second, we should save water in our daily life, turn off the taps in time, take a shower instead of a bath, and always remember to collect and reuse water. Third, let’s try to spread the message about protecting and saving water. Make more people around us know the problem of water shortage and how to help solve it.

Making Posters About Natural Resources
Each group should discuss their own uses, the problems that they face and their wishes. Then give a report in class.
Example:
Uses: I am soil. Plants can’t grow without me. People use me to do many things …
Problems: Sometimes people use too many chemicals in the fields. What’s worse, they put waste into the land … So I’m hurt. Please help me.
Wishes: I hope human beings can protect and take care of me. And then I could do more useful things for them…
