The sun makes the earth hot, but it can not 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, then the cool air over the water moves in and takes the place of the hot air. When you are near a lake or an ocean, you feel the cool air when it moves in. 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 cracks (崩裂) , and rain falls into the cracks. 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 know a lot about our world.

Its a friendly way for Americans to greet each other. But“How are you？”is also a very unusual question. It often doesnt need an answer. The person who asks“How are you?”hopes to hear the answer“Fine”even if the persons friend isnt fine. In fact, they are not really a question or an answer. They are simply other ways of saying “Hello”or“Hi”.Sometimes people also dont say exactly what they mean, For example, when someone asks“Do you agree？”the other person might think，“No，I disagree. I think youre wrong.” But it isnt very polite to disagree so strongly, so the other person might say,“Im afraid ”Its a nicer way to disagree.People also dont say exactly what they are thinking when they finish talking with other people. For example, many phone talks finish when one person says“I have to go now.”O(jiān)ften, the person who wants to finish the phone call gives an excuse,“Someones at the door.”The excuse might be real, or not. Perhaps the person who wants to finish the phone call simply doesnt want to talk anymore, but it isnt polite to say that. The excuse is more polite, and it doesnt hurt the other person.When they are greeting each other, talking about an idea, thinking of finishing a talk, people dont say exactly what they are thinking about. Its an important way that people try to be nice to each other, and it is part of the game of language.（1）“How are you？”is another way of saying“Hello”or“Hi”
