Everyone likes talking about weather. When people meet, they usually say something like “Isn’t it a nice day?” or “Do you think it will rain?”

Different people often want different weather. When a farmer needs water, he hopes it will rain. When people want to take a trip, they hope it will be sunny soon.

How will be the weather? Many people think they can tell (判断) it. But they often have different ideas. Some may say, “It’s cloudy in the east. It will rain tomorrow.” But others may say, “No, it will be sunny tomorrow.” So people like the weather report (报告). It sometimes makes mistakes (错误). Still, it can tell many things about the weather.

March 29 is Earth Day. Everyone on earth should care about and protect the earth!

The earth has warmed by about 1（华氏度） over the past 100 years, but why and how? Well, scientists are not quite sure. Maybe the earth gets warmer and warmer on its own. But many scientists say that people are doing many things which make the earth warmer.

First, greenhouse effect （温室效应） is a very important reason for the change of the earth. People give out too much energy into the air every year. It makes the earth warmer. Climate （气候） change is another important reason. Sometimes it becomes too hot and sometimes too cold. Sometimes there is too much rain and sometimes too little. The change of the climate makes the earth warmer. In turn, the warmth of the earth changes the climate, too.

When the earth becomes warmer, there may be more rain and a rise in sea level. It will affect the growth of plants, animals and people. On a Pacific island,100 people have to move to higher ground because the sea is rising. These people can no longer live on the coast. Before that, two islands without people went underwater in 1999.Scientists say that the seas can rise by nearly one metre by 2100.

People can affect the earth’s air, land and water. As for us, we can do many things to protect the earth. For example, we can use fridges less. We can tell more people about protecting the earth.

It’s sunny and cool in my city now. I’m studying at home. How’s the weather in your city? And what are you doing?

I’m visiting my uncle in Beijing. He works here. It’s sunny in Beijing now. And it’s warm. My two cousins are playing soccer in the yard. My uncle is reading a book at home.
