One cat fell off 32 floors onto the street, but it was just hurt a little. A bear can run as fast as a horse.　 A new-born panda is smaller than a mouse and weighs about 100 grams.　 Elephants are the most careful animals in their love. A male（雄性） elephant may show his lady love for up to three years until the female(雌性) elephant takes his love. They often show their love by touching each other's body. Usually, wolves do not hurt people. For years a Canadian newspaper says that they would give anyone a lot of money if he or she could show that a wolf could hurt a person. But nobody could do that. Wolves do not usually go together though（尽管） they may do this in winter and they only hurt people at an unusual time.

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.

Every living thing on the earth is made up of cells (细胞). Cells grow and make new cells. Most cells are very small and we can’t see them with our eyes. Different cells have different uses. Our skin cells are special ones. The cells on the surface (表面) of our skin are old dead cells. New skin cells are right under the outside. These are the living skin cells. They work for our bodies. They help protect our bodies and heal ( 复原,治愈) cuts.

Our bodies make skin cells all the time. As the old cells fall off, new cells grow in the same place. Each person makes about 18kg of skin cells during his or her life. Surface skin cells fit together closely with no gaps between them. When you cut or burn yourself, you can harm ( 伤 害 ) your skin cells. A small cut will not do much harm. Your skin will quickly heal itself by making new skin cells in just some days. How do skin cells work? First, the cells near the cut get bigger and move into the gap. Next, these bigger cells meet in the middle. They form a new layer (层) of skin cells. Finally, new cells will grow until the gap disappears completely. In this way, your skin can grow and get well itself.

How amazing the tiny cells are! Next time you have a cut, don’t worry about it. Maybe in a few days, you will find it healed.
