The ocean can be a great place to swim and play, it may also be useful in another way. Some scientists think that waves could help make electricity.
“Have you ever been on a surfboard or boat and felt yourself being lifted up by a wave?” asked Jamie Taylor of the Wave Energy Group in Scotland. “There is certainly a lot of energy in waves.”
Scientists are working on using that energy to make electricity. The United States and a few other countries have started doing research on wave energy, and it is already being used in Scotland.
Most waves are created when winds blow across the ocean. “The winds start out by making little ripples (波纹) in the water, but if they keep on blowing, those ripples get bigger and bigger and turn into waves,” Taylor said. “Waves are one of nature’s ways of picking up energy and then sending it off on a journey.”
When waves come towards the coast, people can set up dams(大坝) to block the water and send it through a large wheel called a turbine(涡轮). The turbine can then power an electrical generator(发电机).
We will never run out of wave power. Besides, wave energy does not create the same pollution as oil and coal do.
Oceans cover three quarters of the earth’s surface. That would make wave power seem perfect for creating energy around the world. But there are some disadvantages that need us to pay more attention to.
Jamie Taylor said that wave power still cost too much money. He said that its influence on animals in the sea is still unknown. Besides, wave power would get in the way of fishing and boat traffic.
With more research, “Many of these problems might be solved,” Taylor said. “Finding more energy sources(资源) is very important, for traditional sources of energy like oil and gas may run out some day.”
In the future, when you turn on a light button, an ocean wave could be providing the electricity!

The cost of medical care in the United States is very high. The time and money that doctors spend on their medical education is probably one reason for this problem.
A visit to a doctor's office costs from 15 to 50 dollars. It's so expensive. Many people in the United States think that doctors are overpaid. However, most doctors disagree. They say that they were asked to study medicine for a long time. Tuition for many years of medical education costs a lot of money. Doctors say that it is necessary for most medical students to borrow money from the bank to pay their tuition. Because their money must be repaid to the bank, young doctors need to receive a lot of money for their work. So they charge(收费)people high prices for medical care.
Therefore the cost of medical care in America is high. Because high tuition is one cause of high costs, one way to lower costs would be to have medical school that are free or have low tuition.
【小题1】The underlined word "tuition" in the passage means “______”
【小题2】The main idea of the passage is that______.
【小题3】 The cost of medical care in the USA is very high. What does the writer think about it?

Are you carrying too much on your back at school? I'm sure lots of children of your age will, say "Yes". Not only the students in China have this problem, but children in the United States also have heavy school bags.
Doctors are starting to worry that younger and younger students are having back and neck problems as a result of schools bags being too heavy for them.
"It's hard for me to go upstairs with my bag because it's so heavy, "said Rick Hammond, an 11-year-old student in the US.
Rick is among students who have common school bags with two straps(带子) to carry them, but many other students choose rolling(有滚轮的)bags.
But even with rolling bags, getting up stairs and buses is still a problem for children. Many of them have hurt their backs and necks because of the heavy school bags.
But how much is too much? Doctors say students should carry no more than 10% to 15% of their own body weight(重量).
Scott Bautch, a back doctor, said children under Grade 4 should stay with 10 % . But it is also important that older children don't stay with over 15 %, because their bodies are still growing. "Children are losing their balance(平衡) and falling down with their school bags, "he said.
Parents and teachers are starting to tell children to only take home library books they will be reading that night. Some teachers are using pieces of paper or thin workbooks for students to take home.
One of the best answers is, as some children said, to have no homework at all!
