21、Our earth is in trouble. Our drinking water is becoming dirtier, and the air is not as clear as before. People and factories are polluting the air, rivers, lakes and seas. You might think there is nothing you can do to help. That’s not true. There are many things you can do to help the earth.

Cars burn gasoline. This will produce a lot of CO into the air. Some people believe that CO is making the earth warmer. They think CO thins the clouds above us. The clouds keep us away from the strongest sunlight. So try to walk, ride a bicycle or take a bus. And if you drive a car, drive at a steady speed. This can save some gasoline.

Use fewer things that cannot be used again. When you buy something, consider those made from things that can be used again first.

20、It is believed that Egyptians drive on the right, although many choose to drive along the middle of the road. The most important and necessary part of an Egyptian driver’s car isn’t anything to do with how good, safe or fast the car is —it is the horn (喇叭)!

The horn is sounded to greet friends or to make camels or donkeys move along the street. These animals often cause problems when they are in front of the car. Sometimes, people who are selling small things around the car also cause trouble, so the drivers use the horn to tell them they are not welcome. All of these above reasons have one aim: to keep other road users out of the way. However, there are also some special cases. For example, people can use the horn to allow another road user onto the road, but this seldom happens. They do so only because they feel like it. They also use the horn to warn the poor traffic policeman. They have to be careful when they are on duty at crossroads because Egyptian drivers either are color-blind or don’t understand what the true meaning of a traffic light is. The drivers don’t slow down or stop, mostly because they can’t, even if they want to.

When visiting the capital, Cairo, you will find that it is a busy city, with lots of cars, motorbikes and pollution!

19、Today it is found that most middle school students pay little attention to sports. It’s because they have no interest in sports? It may not be the fact.
