The Earth has warmed by about half a degree(0.50℃)over the last 100 years. It could be getting warmer on its own, but many scientists think that people are making the Earth warmer by making a greenhouse effect. The greenhouse effect is important. Without it, the Earth would not be warm enough for us to live on. But just a little warmer than it is now could cause problems for humans, plants and animals.

Many of the things we do every day can change the Earth’s temperature by sending greenhouse gases into the air. We send greenhouse gases into the air when we watch TV, turn on lights, dry hair, play video games, wash or dry our clothes or drive cars. The rubbish from factories and homes also produces greenhouse gases.

Even a small change in temperature can affect our weather. This can cause changes in the sea levels, the air, flooding, and our fresh water.

The change in the temperature can also cause changes in the living places for animals and plants, endangering many animals.

Global warming is a big problem, and every little bit we do can help. We can save electricity. We can save energy in other ways such as by taking buses or walking rather than driving cars. We can recycle to reduce the rubbish and save natural resources such as trees, oil and metals. We can buy products that don’t do bad to the environment and we can turn to solar energy. Remember the little bit that you do will bring a better world.

Most of us have experienced the anger when we got stuck in the long waiting line of vehicles. 【小题1】

One important advantage of driving cars and motorcycles is that they make our life more efficient. 【小题2】 So now sitting at home, we can plan a trip to a tourist attraction which is a few hundred miles away from where we live.

【小题3】 For example, when we plan to take our family for a trip out of town, we can choose when to start off and when to return, which makes it unnecessary for us to change our plan according to the timetable of the bus or metro.

There is another reason why people like driving. 【小题4】 And for a young man, driving a motorcycle is always a cool thing to do.

【小题5】 So I suggest that we should develop public transport system to protect the environment. In this way, It is much easier for all people to use buses, high-speed rail, and metros.
