Article: Between 1996 and 2010, according to a study published in 2012, the use of computed tomography (CT) scans nearly increased by three times as much, from 52 scans per 1,000 patients to 149 scans per 1,000 patients. And those images certainly provided valuable information to help doctors diagnose hidden conditions that wouldn't have been possible without the added insight. But CT scans produce those detailed images using small amounts of radiation, and while the risk of that exposure is small, on a population level, increased reliance on the scans could drive a slight bump in cancer risk from CT. That's exactly what the latest study, published in the British Medical Journal, found. It's the largest study to date -- involving 10.9 million Australians born between 1985 and 2005. A team of researchers from Australia and Europe studied the cancer rates of Australian patients from birth to 19 years old who had CT scans in early childhood, and compared them to those who did not receive the scans. Most of the cases were followed for 10 to 17 years, and by the end of the study period, 3,150 of the 680,000 patients exposed to CT scans during childhood and young adulthood developed cancer and 57,542 of the remaining participants, who were not exposed, developed cancer. Those who were scanned had a 24% greater risk of cancer than those who did not receive them, with the risk increasing by 16% for each additional CT. The risk was highest for children who received scans before age five; they showed a 35% increased chance of developing a cancer during the study period than those who weren't scanned at this age. That research is still ongoing, however, and in the meantime, doctors and patients are left to find the delicate balance between how necessary scans are to diagnose disease, and their potential risk of causing cancer, which, most experts say, is still very small. "All parties, including patients and families, need to work together to make sure that CT scans are limited to situations where there is a definite ... Question: Among the following, who will face the highest cancer risk after CT scans? Options: A: A one-year-old baby. B: A seven-year-old student. C: A fourteen-year-old teen. D: A twenty-year-old adult.

"Good morning, lady," the man said in a low voice, "I don't think you wish to die here!""What do you want?" Agatha asked. "Your earrings . Take them off!"Agatha suddenly had a bright idea. She tried to cover her necklace with the collar of her overcoat while she used the other hand to take off both of her earrings, and then she quickly threw them on the ground. "Take them and let me go." she said. The robber was uncertain. He saw that the girl didn't care for the earrings at all, only trying to protect the necklace. He realized the necklace would cost more, so he said, "Give me your necklace." "Oh, sir. It's not worth much. Please let me keep it." "Stop talking rubbish. Quick!" With shaky hands, Agatha took off her necklace. As soon as the robber disappeared, she picked up her earrings and ran as fast as she could to her home.

Ques: Read the article and select the best answer. Article: Many Americans are turning to Japan, they think, a country of high academic achievement and economic success, for possible answers. However, the answers provided by Japanese preschools are not the ones Americans expected to find. In most Japanese preschools, surprisingly little emphasis is put on academic instruction. In one survey, 300 Japanese and 210 American preschool teachers, child development specialists, and parents were asked about various aspects of early childhood education. Only 2 percent of the Japanese respondents listed "to give children a good start academically" as one of their top three reasons for a society to have preschools. In contrast, over half the American respondents chose this as one of their top three choices. To prepare children for successful careers in first grade and beyond, Japanese schools do not teach reading, writing, and mathematics, but rather skills such as determination, concentration, and the ability to work as a member of a group. The huge majority of young Japanese children are taught to read at home by their parents. Like in America, there is diversity in Japanese early childhood education. Some Japanese kindergartens have specific aims, such as early musical training or potential development. In large cities, some kindergartens are attached to universities that have elementary and secondary schools. Some Japanese parents believe that if their young children attend a university-based program, it will increase the children's chances of eventually being admitted to top-rated schools and universities. Several more progressive programs have introduced free play as a way out for the heavy intellectualizing in some Japanese kindergartens. Question: Why do some Japanese parents send their children to university-based kindergartens? Options: A: They can do better in their future studies. B: They can make more group experience grow there. C: They can be individually oriented when they grow up. D: They can have better chances of getting a first-rate education.
Ans: D

Ques: Read the article and select the best answer. Article: A new study of 8,000 young people in the journal ofHealthandSocialBehaviorshows that although love can make grownups live healthily and happily,it is a bad thing for young people.Puppy love may bring trouble for young people and can cause depression .The study shows that girls become more depressed than boys,and young girls are the worst of all. The possible reason for the connection between love and higher risk of depression for girls is "loss of self".According to the study,even though boys would say "lose themselves in a romantic relationship",this "loss of self" is much more likely to cause depression when it happens to girls.Young girls who have romantic relationships usually like hiding their feelings and opinions.They won't tell that to their parents. Dr.Marianm Kaufman,who works on young people problems,says 15% to 20% of young people will have depression during their growing.Trying romance often causes the depression.She advises kids not to jump into romance too early.During growing up,it is important for young people to build strong friendship and a strong sense of self.She also suggests the parents should encourage their kids to keep close to their friends,attend more interesting school activities and spend enough time with family. Parents should watch for their children's eating or mood changes.If they see some,they need to give help.The good news is that the connection between romance and depression seems to become weak with age.Love will always make us feel young,but only maturity gives us a chance to avoid its bad side effects.
