When the weather is hot, you go to a lake or an ocean. When you are near a lake or an ocean, you feel cool. Why? The sun makes the earth hot, but it cannot make the water hot. Though the air over the earth becomes hot, the air over the water stays cool. The hot air over the earth goes up, and then the cool air over the water moves in and takes the air near a lake or an ocean, you feel the cool air when it moves around you. You feel the wind and the wind makes you cool.

Of course, scientists cannot answer all of our questions. If we ask “Why is the ocean full of salt?” scientists will say that the salt comes from rocks. When a rock gets very hot or very cool, it breaks, and rain falls into the cracks(裂缝). The rain then carries the salt into the earth and the rivers. The rivers carry the salt into the ocean. But then we ask “What happens to the salt in the ocean?” The ocean does not get saltier every year. Scientists are not sure about the answer to the question.

We have known a lot of things on the earth, but there is still a long way to go about the study of our world.

Children all over the world like to celebrate their birthdays. American children are of no difference. They usually celebrate with a party. They invite friends to their birthday parties. The party may not be held on the right date of their birthday if it comes on a school day. It may be held on the weekend instead.

Today two kinds of parties are the most popular. One is held at home. Parents decorate the house with beautiful balloons and colored paper. They prepare a special birthday meal. The children play games. The other kind is held away from home. Some are at a special restaurant. The children eat pizza and ice cream. The waiters, who serve the food, also sing and tell jokes to the children. Other parties may be held at a park, or at a movie theater, or in some other places.

Every birthday party has a cake with candles. There is one candle for each year of a birthday boy’s or girl’s age. When the candles are lighted, everyone sings the special birthday song: Happy Birthday to You.
