Rats that eat high levels of a natural sugar known as fructose seem to age faster than other rats.and the same could be true for people who eat too much sweet junk food,Israeli researchers said Monday. Fructose,found naturally in honey and fruit,is used widely in foods ranging from soft drinks to yogurt.But while its sweet taste is popular,the sugar could cause wrinkles,the researchers said.Dr.Moshe Werman and Boaz Levi of the Technion-Israel Institute of Technology fed large amounts of fructose to laboratory rats.Writing in the Journal of Nutrition,they said the fructose-fed rats showed changes in the collagen of their skin and bones.Collagen basically holds the body together.The loss of collagen is what causes loose skin and deep wrinkles in older people. The process affected,Werman's team said,is known as"cross-linking "."Too much cross.1inking makes the skin stiff, and these are the conditions that encourage wrink1ed skin,"Werman said in a statement.He said the same could be true of people,although this has not been shown."Americans are eating more and more processed foods such as baked goods,canned fruits,jams is and dairy products that contain fructose,"Werman said.Other studies have shown that taking in high fructose may cause diabetes . The rats Werman worked with were fed much more than the average adult person might eat in a day,which is standard in such experiments.The rats were fed 12.5 grams of fructose per kg of weight everyday for a year. Why do older people have deep wrinkles according to the passage? A) They don't drink enough water every day. B) They don't take enough exercise every day. C) Collagen in their body is lost. D) Their daily foods do not contain enough fructose.

Everyone gathered around and Paddy read out loud, slowly, his tone growing sadder and sadder. The little headline said: BOXER RECEIVES LIFF SENTENCE. Frank Cleary, aged 26, professional boxer, was today found guilty of the murder of Albert Gumming, aged 32, laborer, last July. The jury reached its decision after only ten minutes, recommending the most severe punishment to the court. It was, said the Judge, a simple case. Cumming and Cleary had quarreled violently at the Harbour Hotel on July 23rd and police saw Cleary kicking at the head of the unconscious Gumming. When arrested, Cleary was drunk but clear-thinking. Cleary was sentenced to life imprisonment with hard labour. Asked if he had anything to say, Cleary answered, "Just don't tell my mother." "It happened over three years ago," Paddy said helplessly. No one answered him or moved, for no one knew what to do. "Just don't tell my mother," said Fee numbly . "And no one did! Oh, God! My poor, poor Frank!" Paddy wiped the tears from his face and said. "Fee, pack your things. We'll go to see him." _ "I can't go," she said without a hint of pain, yet making everyone feel that the pain was there. "It would kill him to see me. I know him so well--his pride, his ambition. Let him bear the shame alone, it's what he wants. We've got to help him keep his secret. What good will it do him to see us?" Paddy was still weeping, not for Frank, but for the life which had gone from Fee's face, for the dying in her eyes. Frank had always brought bitterness and misfortune, always stood between Fee and himself. He was the cause of her withdrawal from his heart and the hearts of his children. Every time it looked as if there might be happiness for Fee, Frank took it away. But Paddy's love for her was as deep and impossible to wipe out as hers was for Frank. So he said, "Well, Fee, we won't go. But we must make sure he is taken care of. How about if I write to Father Jones and ask him to look out for Frank?" There was no excitement in the eyes, but a faint pink stole into... What is Frank and Paddy's probable relationship with Fee? A) Frank is Fee's son and Paddy is Fee's brother. B) Frank is Fee's son and Paddy is Fee's husband. C) Frank is Fee's brother and Paddy is Fee's lover. D) Frank is Fee's lover and Paddy is Fee's husband.

Question: For high school leavers starting out in the working world, it is very important to learn particular skills and practice how to behave in an interview or how to find an internship . In some countries, schools have programs to help students onto the path to work. In the United States, however, such programs are still few and far behind. Research shows that if high schools provide career-related courses, students are likely to get higher earnings in later years. The students are more likely to stay in school, graduate and go on to higher education. In Germany, students as young as 13 and 14 are expected to do internships. German companies work with schools to make sure that young people get the education they need for future employment. But in America, education reform programs focus on how well students do in exams instead of bringing them into contact with the working world. Harvard Education school professor Robert Schwartz has criticized education reformers for trying to place all graduates directly on the four-year college track. Schwartz argued that this approach leaves the country's most vulnerable kids with no jobs and no skills. Schwartz believed that the best career programs encourage kids to go for higher education while also teach them valuable practical skills at high school. James Madison High School in New York, for example ,encourages students to choose classes on career-based courses. The school then helps them gain on-the-job experience in those fields while they're still at high school. However, even for teens whose schools encourage them to connect with work, the job market is _ . In the US, unemployment rates for 16-to-19-year-olds are above 20 percent for the third summer in a row. "The risk is that if teenagers miss out on the summer job experience, they will become part of this generation of teens who had trouble in landing a job," said Michael, a researcher in the US. In the author's opinion, German high school leavers _ . A) enjoy more career-related courses than that of US B) need more career advice from their schools C) perform better in exams than American students D) are less brought into contact with the working world
