“It was all his own idea, ” says Pat Peters, the 38-year-old wife of Palo Alto, California high school football coach Bob Peters, 39. Bob had just drawn up a “motherhood contract” --a document stating that for 70 days this summer he would take over the care and feeding of the couple’s four children, plus all household chores. Although he didn’t even know how to make coffee when he signed, he was quite confident.(He thought the experience would make a nice book.)
After 40 of the 70 days, he was ready to give up. “I was beaten down, completely humbled（挫败的）,”  admits Peters. Three weeks later he spoke to the local press, stating, “Not only is motherhood a difficult task, not only is it never-ending, it is an impossible job for any normal human being.”
Bob and Pat were high school sweethearts. After they were married in 1960, she worked as a secretary to help put him through university. Since then Bob has been the football and wrestling coach at Palo Alto’s Cubberley High while Pat raised the kids. Then two years ago Pat went back to work as a secretary at Cubberley. “I had been around children so much,” she sighs, “I couldn’t talk to a grown-up.” She continued to run the household, however----until Bob signed the contract, therefore, she decided to relax and enjoy it. 
Although Peters had consulted(咨询) with his school’s home economics teachers and the head of the cafeteria, his meals were sometimes a disaster. “I tried to slip the butter I’d forgotten under the eggs after they were frying, ” he says. For the last three weeks, the family ate out a lot—sometimes having Macdonald’s hamburgers for lunch and dinner.
As for housekeeping, a home economics teacher had told Bob that a room always looks clean if the bed is made. “I found an easier way-I shut the doors, ” he says. Soon the kids were wearing the same clothes for a week. “I made them wear their shirts inside out, and when we went to pick up Pat at work they turned them right side out so they would look clean.”
Now that Bob has publicly admitted he was wrong, he is routinely sharing the child-raising and household tasks with Pat. The tentative（暂时的） title of his book about the summer is taken from something he shouted at the kids one day.

It is natural that children are curious about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.

　　As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、职业) in science.

　　Scientists spend their lives trying to find out about the world．Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .

　　These scientists have already discovered a lot about our world．For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.

　　Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty” scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into 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 this question.

　　We know a lot about our world, but there are still many answers that we do not have, and we are curious.
