Scientists study the world and learn about things using a process called the scientific method(方法). By asking important questions and 16 the answers, it is possible to make amazing discoveries! Sometimes a scientist is 17 to answer his own questions, but if he has taken good notes another scientist may come along later who is able to use new knowledge to answer it.
When you use the scientific method to 18 an experiment, you start by making observations(观察) about something that 19 you. Based on your observations, you make a hypothesis. This is using 20 you know to make a smart guess about what you think could happen. Then you are ready to begin your experiment. All 21 your experiment you take down notes, which are 22 experiment date(资料). You are constantly making observations during this time. You may make discoveries that cause you to improve your experiment as you go. 23 , you conclude your experiment and begin to look over your notes to decide what it all means. Based on what you have learned, you make a final statement about 24 your hypothesis was correct or not. You have to have reasons and evidence to support what you are saying.
Using the scientific method can be difficult, but rewarding. Because all the steps are organized in a process, the 25 are more valid(可信的). When you provide observations as evidence to support what you are saying, your ideas are more likely to be accepted.

“Isn’t that work?” Ben asked.
“Well, no. Does a boy get the opportunity to paint a fence every day? You’ve never painted a fence, have you? Auntie says I have to do it with great care!’
“Pleas, Tom. Let me do a little,” said Ben.
“No, Ben. If you do, you’ll do it wrong. You can’t paint very well. If it was the back fence wouldn’t mind, but it isn’t.”
“I won’t do it wrong. I’ll be really careful. I’ll give you my apple.” Tom gave him the brush and paint with a sad face, but in his heart he was glad, His trick had worked.

Why do people cry? Scientists say the body produces tears because they need them. One kind of tears is for the eye, the other is for the heart. They both work as cleaners. If something else like dust(灰尘) gets into your eye, tears also come into the eye to clean it out. If you are hurt by something, your strong feelings produce some poisonous chemicals(毒素) in your body, and at the same time, tears come out with them. If these poisonous chemicals are not cleaned out of your body as soon as possible, they will do harm to the heart sooner or later.
In the United States men have heart problems more often than women do. Doctors say heart problems have something to do with the pressures(压力) of living and working now. Perhaps men suffer more from these illnesses because they do not cry enough. They need to cry more.
In fact, you can find many ways of reducing the pressures to keep fit. Crying is a natural and physical one.
小题1:How many kinds of tears does the body usually produce?
小题2:What do tears do when dust gets into your eye?
小题3:Will the poisonous chemicals in the body do harm to the heart?
小题4:Why do men suffer more from heart problems than women?
小题5:What will you do to reduce the pressures of living and working to keep fit? Please give TWO examples.

Arnold says, “Every time I stop the boat, she always comes to me, turns on her back and lets me pet (抚摸) her body and neck. She sings, turns her eyes, and moves her fins (鳍) up and down, hits the water 9 .”
Cindy is 10 an interesting animal that Arnold has to try to go fishing in different places. Doesn’t Cindy know what her action means? Maybe she really doesn’t understand.
