Ques: Read the following article and select the best answer. Article: WASHINGTON (Reuters) - People who drink two or more sweetened soft drinks a week have a much higher risk of pancreatic cancer , an unusual but deadly cancer, researchers reported on Monday. People who drank mostly fruit juice instead of sodas did not have the same risk, the study of 60,000 people in Singapore found. Sugar may be to blame but people who drink sweetened sodas regularly often have other poor health habits, said Mark Pereira of the University of Minnesota, who led the study. "The high levels of sugar in soft drinks may be increasing the level of insulin in the body, which we think contributes to pancreatic cancer cell growth," Pereira said in a statement. Writing in the journal Cancer Epidemiology, Biomarkers & Prevention, Pereira and colleagues said they followed 60,524 men and women in the Singapore Chinese Health Study for 14 years. Over that time, 140 of the volunteers developed pancreatic cancer. Those who drank two or more soft drinks a week had an 87 percent higher risk of being among those who got pancreatic cancer. Pereira said he believed the findings would apply elsewhere. "Singapore is a wealthy country with excellent healthcare. Favorite pastimes are eating and shopping, so the findings should apply to other western countries," he said. But Susan Mayne of the Yale Cancer Center at Yale University in Connecticut was cautious. "Although this study found a risk, the finding was based on a ly small number of cases and it remains unclear whether it is a causal connection or not," said Mayne, who serves on the board of the journal, which is published by the American Association for Cancer Research. Pancreatic cancer is one of the deadliest forms of cancer, with 230,000 cases globally. In the United States, 37,680 people are diagnosed with pancreatic cancer in a year and 34,290 die of it. Question: We can infer from Pereira's words that _ . - the healthcare in Singapore should be greatly improved - 2 soft drinks a day are considered harmful to health - sugar might not be the only cause of pancreatic cancer - 87 out of 140 volunteers developed pancreatic cancer
Ans: 87 out of 140 volunteers developed pancreatic cancer

Ques: Read the following article and select the best answer. Article: Some 80 percent of graduate students in East China's Zhejiang Province said in a survey they will give up trying to find jobs in Beijing,Shanghai and Guangzhou,first-tier cities in China that have been considered dream places for many,because of the untouchable home prices and high living costs. The Yangtse Evening Post conducted the survey among 50 job seekers who were attending Sunday's job fair in Jiangsu for graduate students.The survey showed graduates are becoming more realistic in their job search despite the job market becoming better. The fair attracted more than 10,000 graduate students with 7,382 positions. "The pressure of buying a house in Beijing is unbelievable,"said Wang Jian from Nanjiing Normal University,who acknowledged he had thought about finding a job in Beijing,Shanghai or Guangzhou,but in the face of huge pressures,he has no choice but to be "realistic". People can have a very comfortable life in Nanjing with a monthly salary of between 3,000 yuan($450)and 4,000 yuan,but in Shanghai,5,000 yuan a month can only help you survive and buying a house will remain a dream. A student from Nanjing University of Science and Technology said he just turned down an offer from a Shanghai company of 7,000 yuan a month because"living costs in Shanghai are too high." An unnamed male student from Nanjing University said he will try first-tier cities only if he can get a high salary."I would go to Beijing only if I can earn 200,000 yuan a year,"he said. "Beijing,Shanghai and Guangzhou once had the advantages that other cities don't have,but the high housing prices and living costs make young people barely able to breathe,"said Ren Leiming from the job service center of Jiangsu's colleges and universities. "First-tier cities have plenty of talents that make it hard for people to be outstanding,and if you go work in smaller cities you can become a dominant player at your position much more easily,"said Ren. Question: The majority of graduate students will give up trying to find jobs in the first-tier cities because _ . - it is not easy to find jobs there. - home prices and living costs there are very high. - they can't make full use of their knowledge and skills there. - monthly salaries there are low compared with those in other cities.
Ans: home prices and living costs there are very high.

Ques: Read the following article and select the best answer. Article: What could be cuter than your puppy giving his doggy friend a kiss on the nose? Nothing, really. But is your dog actual-fly planting a kiss on his friend? Yes, but that's only one of the reasons your dog may lick another dog's nose. Here are some other reasons why your dog may lick another dog's nose. During an introduction, a shy and lower-ranking dog will lower his head, avoid direct eye contact and gently extend his tongue to lick the nose of a more confident and high-ranking dog. The first dog licks the nose of the second dog to simply make it know that:he comes in peace. Dogs who are already friends will also trade kisses. Two strongly bonded dog pals will lick and clean each other. They give each other "dog kisses" showing friendship. Puppies also "kiss" their mothers, but it's not a gesture of love. When puppies stop suckling their mothers' tits for milk and start to eat semisolid food instead;they lick their mothers' mouths and noses in the hope of getting the mother to regurgitate some semi-digested food. So how to help your _ dog make friends with other dogs? You can carefully select confident-but-friendly and good-tempered dogs to play with your shy dog, to help him develop his social skills. Also consider taking him to a special training class that focuses on socialization and positive training technique. Do not disturb them when your two dogs play "kiss" briefly with each other. Sit back and enjoy this display of friendship. Then call them over and have them do a command such as "sit'' or "shake paws". Offer them treats as a reward for being good to each other. If you foster a dog and have three or more resident dogs, introduce the foster dog to your brood dog one at a time and let muzzle licking between them happen naturally. Start with your least reactive or most friendly dog. Never force an in production between the dogs because this can deepen the foster dog's submissiveness or spark a fight.
