Hundreds of years ago, life was much harder than it is today. People didn't have modern machines. There was no modem machine, either. Life today has brought new problems. One of the biggest is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and affects our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution. It affects all living things in the world.
Many countries are making new laws to fight against pollution. Factories must now clean their water before it is thrown away: they mustn't blow dirty smoke into the air.
We need to do many other things, We can put waste things in the dustbin and not throw them on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution.www.21-cn-jy.com

Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and men can't make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore, animals and men need plants in order to live. This is the reason why we find so many plants around us.
If you look carefully at the plants around you, you will find that there are many kinds of plants. Some plants are large while others are small. Most plants are green.
Some plants have many small leaves. Others have only a few. There are many kinds of leaves. Leaves are of different shapes and colors.
Leaves are also different in other ways. Some leaves have long thin parts at the end, we call them leaf stalks, some have short leaf stalks, others even have no leaf stalks. The leaf edges are also different. Some leaves have smooth(平滑) edges. Some have wave-shaped edges. Others have edges like the teeth of a saw(锯子).

The world is not hungry, but it is thirsty. It seems strange that nearly 3/4 of the earth is covered with water while we say we are short of water. Why? Because about 97% of the water on the earth is sea water which we can't drink or use for watering plants directly. Man can only drink and use the 3%—the water that comes from rivers and lakes. And we can't even use all of that because some of it has been polluted.
Now more water is needed. The problem is: can we avoid(避免) a serious water shortage later on? First, we should all learn how to save water. Secondly, we should find out the ways to reuse it. Scientists have always been making study in this field. Today, in most large cities water is used only once and then runs to the sea or rivers. But it can be used again.
Even if every large city reused its water, still there would not be enough. What could people turn to next?
The sea seems to have the best answer. There is a lot of water in the sea. All that needs to be done is to get the salt out of the sea water. This is expensive, but it's already in use in many parts of the world.
Scientists are trying to find a cheaper way of doing it. So you see, if we can find a way out, we'll be in no danger of drying up.
