April 22 is Earth Day. Everyone on Earth should care about and protect the earth!
The earth has warmed by about 1°F (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 makes 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.

Most kids hate doing housework. However, not all hope is lost. There are some things that you can do to get your kids to help you clean your house. If you are struggling with the chores (家务)and need your kids to help you, take a look at some of the creative ways in this article.
If you are dealing with older kids, you may want to try the allowance deal. You can give your kids a list of chores that need to be done each week. If they complete these chores, you can give them some money. You can also break the list down and tell them they will get so much for each chore that is finished. Older kids , who like to do things on weekends or buy things like video games, will work hard to complete their chores and earn their money. This is also teaching them responsibility. This is teaching them that they must work for what they want.
If you are dealing with younger kids, you may want to go with the rewards chart(奖励图表）. This is where you design a chart and list their chores on the chart. For each chore they complete, you can put a red flower beside it. For the rewards, you canalso do a number of things ,such as going to the park, going out to eat, buying a DVD or something similar. The rewards would be up to you because you know what your kids like.
For real small kids, you can turn it into a game. When kids were much younger, you can teach them to dance around and sing as you cleaned. The kids loved it and would do a wonderful job at picking up their toys. So, consider turning cleaning into a game for the real small kids.
