As we all know, the ocean moves. But waves breaking on the beach make the ocean fun. When you stand on the shore and look at the waves, it seems like the water is moving towards you. But the water is not really moving forward. The moving you see is wave energy. And wave energy comes from the wind.
Let’s think about how this works. As wave energy passes through the water, the energy makes particles (粒子) of water move up and down. Just give you an example of a wave passing under a basketball. We put a basketball on the sea. When the wind blows, a wave comes from behind the basketball. The basketball moves up to the top with the wave. Then the wave continues and leaves the basketball behind. The basketball looks lower, but it doesn’t move forward. That’s because the wave energy just moves the water which is under the basketball.
So why can you see a wave knock you down on the shore?When a wave moves toward the shore, the bottom of the wave slows down because it meets the ocean floor. But the top, which is called crest(浪峰), keeps moving. The different action causes the wave to fall over or break onto the shore. If a wave is very large, it carries a lot of energy when it hits the land. As time goes by, waves can break up and carry away the rocks and other things on the shore. Shorelines are changing all the time because of wave action.

People say that George Washington, the first president of the United States, never told a lie. But it seems that the president was not without faults.
A New York library recently found that Washington borrowed two books from the library in 1789. He didn’t return them.
If he were still alive, he would have to pay the library $300,000 for being 220 years late.
On October 5, 1789, when the first president borrowed the books form the New York Society Library, he didn’t sign his name in the borrower’s book. He just wrote “president” to show who had taken them out.
The two books should have been brought back a month later but were never returned. Workers at the library realized the books were missing.
The New York Society Library doesn’t expect anyone to pay the fine. But it hopes that someone will return the books.
【小题1】Gorge Washington is__________.
A.the president of the US now |
B.the first president of the US |
C.the first black president of the US |
D.the president who always borrowed the books without returning them back |
A.the Washington Public Library |
B.the New York Society Library |
C.the Paris Society Library |
D.the Chinese Public Library |
A.Gorge Washington will return the book. |
B.Gorge Washington will pay the fine |
C.someone will find the book and return it |
D.someone will pay the fine for the president |
In the West, some people believe that personality can be predicted according to the time of the year the person was bor. From China comes the belief that the year of birth influences one’s personality. In the past century, a new belief ahs arisen: the idea that personality is related to one’s ABO blood type. People with blood type A, for example, are considered more likely to be serious, hard-working, and quiet, while people with blood type O are likely to be popular and outgoing, yet often unable to finish what they start. Though this belief continues to be strong, some people question whether it is true.
The blood-type personality theory(理论) started in Japan in 1927 when Furukawa Takehi noticed personality similarities and differences among his workers. This idea soon went out of fashion, but was brought back by a Japanese television host named Toshitaka Nomi in the 1970s. The belief is still strong in Japan and is increasingly popular in neighboring countries. Some young Koreans have taken to the theory. A recent study showed 76 percent of Koreans aged between13 and 64 believing in the blood-type personality connection. Though most Asians might believe in the blood-type theory, for many it seems harmless and not something to be taken too seriously.
Is the belief true? The scientists in Asia largely think the belief as a modern-day superstition(迷信). Most studies have failed to find any strong connection between blood and personality. Generally, scientists are against making predictions or important decisions based on this questionable theory.
【小题1】The writer uses blood type A and O as an example to explain ________.
A.the difference between the two blood types |
B.the relationship between the two blood types |
C.the influence of blood type on one’s behavior |
D.the connection between personality and blood type |
A.They don’t believe it. |
B.It was brought back by them. |
C.They liked and accepted it. |
D.They stole the idea from others |
A.Most scientists in Asia don’t believe in the theory. |
B.The blood-type theory began in Japan in the 1970s. |
C.The blood-type personality theory is about blood type. |
D.People don’t change their personality to match the theory. |
A.Is the blood-type theory changeable ? |
B.Is the personality changeable? |
C.Is it in your blood? |
D.Is it in you mind? |
In the UK, most children have their lunches at school, but in some schools, parents can choose what their children eat. The children can have a school dinner-a hot, cooked meal; or they can take a packed(包装的) lunch with them, which usually includes cold food like sandwiches.
Often parents know what their children want. Cath, a mother of three children, told us, “My children have packed lunches because they say they don’t like to have school dinners. So I make three packed lunches every morning.”
However, another mother, Susan, made a different choice. She said, “My daughters have a always had school dinners. I think they probably get healthier food at school than a few sandwiches I make for them.”
But how healthy are school dinners? Kaz, a father, thought poorly of them. He said, “Fizzy(起泡的) drinks were offered and I think there were a lot of chips.”
Jamie Oliver spent a year working in a school kitchen. He was worried about the unhealthy food which included burgers, pizzas and chips. So he tried to cook healthy food such as good stews and curries for the children instead.
So Jamie improved the school dinners, and trained the dinner ladies to cook healthy food in that school. Then he advised the government to improve school food across the country. And it seems that the changes have begun.
Anna, a pupil, told us, “We used to have a fast food window where you got chips and coke, but they stopped that this year. There’s a salad restaurant, which is good, so it’s healthier than it was.”
