She lays all these eggs in just a few minutes. Large sea turtles live in the warm seas of the world. Except for when they lay their eggs, they spend their whole lives in the water. When it is time to lay their eggs, the females swim to land. They usually return to the place where they themselves were born. How they find their way back there is unknown. When they reach shore, the big, heavy turtles crawl slowly up to the high water mark. Using their flippers, they pull themselves along the sand. They must struggle like mountain climbers. When they finally reach dry sand, they rest before beginning the difficult task of laying eggs. The turtles lay the eggs in deep holes and cover them with warm sand. The sand protects the eggs from harm. Then the females leave them. After a few weeks, if you happened to be walking along the beach, you might see the sand begin to shake. You may see tiny black balls coming out of the sand. The tiny heads of baby turtles! Question: The writer compares turtles to climbers _ .

A study found going without sleep for just one night causes changes in the brain similar to those that occur after a blow to the head. The researchers said the healthy young men examined in the study showed a sudden increase in the same chemicals which indicate brain damage. Professor Christian Benedict, of Uppsala University, Sweden, explained that the chemicals NSE and S-100B are biomarkers for brain damage, such as concussion . He said, "What we found was their levels in the blood rose in the group that went without sleep for a night. This was not to the extent that would happen after a head injury, for instance, but it was still significant. During sleep, the brain cleans poisonous substances off itself." Benedict also said previous studies which linked a lack of sleep with increased risk of Alzheimer's, Parkinson's and multiple sclerosis could applaud his study. The rise of the chemicals in the blood after sleep loss may suggest not getting enough sleep contributes to a loss of brain tissue, he explained. Benedict, whose study is published in the journalSleep, added, "In conclusion, the findings of our experiment indicate a good night's sleep may be critical to maintaining brain health." A third of the UK population suffer from sleep-related problems, while the average person now sleeps for only seven hours a night, compared with almost nine a few decades ago. Many scientists believe irregular sleeping patterns lead to illnesses ranging from aches and pains to heart disease, while less than eight hours' sleep a night can lower the IQ the next day. Question: If you don't sleep for a night, what will happen? Options: A: NSE and S-100B will increase. B: The brain damage will be likea head injury. C: You will suffer from concussion. D: The brain will get rid of poisonous substances.

Q: Read the article and select the best answer. Article: Many years ago,a French naturalist,the Count de Buffon,wrote some books about natural history.The books were a great success even though some critics did not like them.Some critics said,"Count Buffon is more of a poet than a scientist." Thomas Jefferson did not like what the Count had said about the natural wonders of the New World.It seemed to Jefferson that the Count had spoken of natural wonders in America as if they were unimportant. This troubled Thomas Jefferson.He too was a naturalist,as well as a farmer,inventor,historian,writer and politician.He had seen the natural wonders of Europe.To him,they were no more important than those of the New World. In 1788,Thomas Jefferson wrote about his home state,Virginia.While writing,he thought of its natural beauty and then of the words of the Count de Buffon.At that moment.Jefferson created a new word--belittle.He said."The Count de Buffon believes that nature belittles her productions on this side of the Atlantic." Noah Webster,the American word expert,liked this word.He put it in this English language dictionary in 1806,"Belittle--to make small,unimportant." Americans had already accepted Jefferson's word and started to use it.In 1797,the Independent Chronicle newspaper used the word to describe a politician the paper supported."He is an honorable man,"the paper wrote,"so let the opposition try to belittle him as much as they please." In 1872,a famous American word expert decided that the time had come to kill this word.He said,"Belittle has no chance of becoming English.And as more critical writers of America,like those of Britain,feel no need of it,the sooner it is forgotten,the better." This expert failed to kill the word.Today.belittle is used where the English language is spoken. Question: We can infer that Jefferson created the word"belittle"out of his . Options: A: anger B: excitement C: kindness D: responsibility

Q: Read the article and select the best answer. Article: Richard Wagner was a German musician has been a very controversial person, but he has gained great fame by writing opera, a form of performance combining singing, music on instruments, and drama. While he wrote excellent music, many people think his operas are too dark and serious, lacking the fun common in operas written before his time. Wagner, on the other hand, thought the opera of his time was too simple.He wanted to make opera a serious form of art that combined drama and music to tell deep stories that would have a strong effect on the audience. Some people thought Wagner's new kind of music was too different from the operas they were used to hearing.Wagner agreed with them.In fact, he didn't call his works "operas" at all, using instead a German word that means "Musical Festival" or "Musical play". While many people today still do not like Wagner's operas, they cannot deny that Wagner has had a lot of influence on opera as a form of art.Wagner invented the tradition of turning off the lights before starting a play.He also was the first person to make the whole audience sit down for an entire play.Today, almost all operas are performed in this manner. Wagner as a man was even more controversial than Wagner as a writer of music.He hated Jewish people, and made many people angry, which we would today think of as evil.Some would say he was a good musician, while others would say that he was a bad musician.But it would be difficult to say he was not an important person in music and in the world. Question: Which of the following best expresses the main idea of the passage? Options: A: Richard Wagner is not worth talking about B: Richard Wagner has made many people angry C: Richard Wagner has contributed much to opera. D: Richard Wagner is a very controversial man.
