Coffee is one of the world's most widely-enjoyed drinks. Now, a new research suggests that if you drink enough coffee, it might help you avoid certain kinds of cancer. Dr. Mia Hashibe of the University of Utah School of Medicine was interested in the connection between coffee drinking and certain cancers of the head and neck. Researchers have looked into this before, but without reaching any firm conclusions. She said, "So this finding from our new study was quite a surprise. We didn't really have any expectation of which direction it could go into." To sort out the confusion, Hashibe and her assistants used statistical ( ) techniques to, in effect, make one big study out of the earlier smaller studies. She explained, "Thanks to the earlier studies, we have a lot more power than earlier studies that looked at this. And we included 4,000 cancer patients who have cancer of the mouth and throat. And then 9,000 controls, people who do not have cancer. ' Those studies--in Europe and the United States--found that people who drank a lot of coffee were less likely to develop cancers of the mouth and throat. "We saw a protective effect for drinking more than 4 cups of coffee per day," Hashibe said. "This was the 40 percent decrease in risk. We did not see the same effect for drinking three cups or less per day." Mia Hashibe said there was a weak connection between cancer risk and drinking coffee without caffeine. And she and her assistants found no proof that drinking tea provided the same protection as drinking Coffee. Their research is published in the journal Cancer Epidemiology, Biomarkers & Prevention. Hashibe says it is not clear how coffee might protect drinkers from certain cancers. "There are a few chemicals that are known to be antioxidants in coffee. So we are thinking perhaps they are playing some sort of protective role against several cancers." What would be the best title for the text? A) Drinking Coffee May Protect Some Cancers B) Drinking Coffee May Prevent Some Cancers C) Drinking Coffee May Cure Some Caneers D) Drinking Coffee May Cause Some Cancers

Thunder was coming when Reginald Eppes woke up at five in the morning. He checked the weather forecast. A violent storm was coming ,but it sounded like his small town wouldn't be hit too hard. But Eppes, a firefighter, had clearly known the power of these huge storms from experiences. "Do you know where the flashlights are?" he asked his wife. Danielle. Just then, thunder was all-around them. The moment he turned the flashlight on. The house lights went off. A second later, the kitchen windows were broken. Eppes and Danielle ran to their boys who were still sleeping in their bedroom. "Get up, get up, R.J.! " Eppes shouted, waving his flashlight. The sleepy boy moved to the edge of the bed. Eppes held out his arms and ordered his son to jump. He was too late. The roof was torn down. R.J. was buried ,under the pieces. "I've lost him," Eppes thought. Quickly, he hurried to Joel to shield him. Glass, wood, and plaster ( ) hit them. Then something huge, heavy-maybe the washing machine-knocked into him. He hurt his arms, but he still held the flashlight in one hand. After a long period, the wind began to die down. Eppes found himself standing in the ruins of his home. Darkness lay all about him. Then he thought he saw a shape moving straight toward him. It was R.J., guided home by the light of his father's flashlight. At the hospital later, R.J. described what had happened to him. "I rushed out when the wall started moving I was scared. My mom and dad were gone. Pieces of glass hit my back, and something hit my neck really hard. " R.J. had been raised up into the air by the wind and dropped back to the ground. Amazingly, R.J. was not hurt badly. Of all his family, Eppes was hurt most seriously. Which of the following is TRUE according to the passage? A) Eppes was still sleeping when the storm happened. B) R.J. was buried in the ruins before he could get out of his bed.

Ques: Do you know why different animals or pests have their special colours? Colours in them seem to be used mainly to protect themselves. Some birds like eating locusts. but birds cannot easily catch them. Why? It is because locusts change their colours together with the change of the colours of crops. When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown colour as crops have. Some other pests with different colours from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night. If you study the animal life, you'll find the main use of colouring is protecting themselves. Bears, lions and other animals move quietly through forests. They cannot be seen by hunters. This is because they have the colours much like the tree. Have you ever noticed an even more strange act? A kind of fish in the sea can send out a kind of very black liquid when it faces danger. While the liquid spread over, the enemies cannot find it. And it immediately swims away. So it has lived up to now though it isn't strong at all. Bears and lions can keep safe because they _ . A) have the colours much like the trees B) move quickly C) like brown and grey colours D) live in forests
Ans: A
Ques: Will it matter if you don't have your breakfast? A short time ago, a test was given in the United States. People of different ages, from 12 to 83, were asked to have a test. During the test, these people were given all kinds of breakfasts, and sometimes they got no breakfast at all. Scientists wanted to see how well their bodies worked when they had different kinds of breakfasts. The rules show that if a person eats a right breakfast, he or she will work better than if he or she has no breakfast. If a student has fruit , eggs, bread and milk before going to school ,he or she will learn more quickly and listen more carefully in class. The result is opposite to what some people think. Having no breakfast will not help them lose weight. This is because they are so hungry at noon that eat too much for lunch. They will gain weight instead of losing it. You will lose weight if you reduce your other meals. Which of the following sciences is not right? A) It is bad for your health to have no breakfast. B) No breakfast and more lunch may make you fatter. C) The more breakfast you have, the more quickly you will learn in class. D) If you don't eat much for lunch and supper, you may lose weight.
