Question: I'm taking a test and have to guess the right answer to the question after the article. Article: In 1966,Allen and Beatrice Garden, two professors at the University of Nevada in Reno, had a bright idea.They were interested in the evolution of language and the language abilities of great apes . Previous attempts to teach chimpanzees to talk had ended in failure and the matter was considered by most people to be closed. But the Gardens realized that speech and the language are not the same thing. Many deaf people, for example, are unable to speak but are perfectly able to communicate by gestures that have all the features of spoken language. The Garders suspected that previous experiments had failed because chimpanzees are physically unable to speak. They therefore decided to try teaching a chimpanzee to sign in the way that deaf people do. And their chosen _ , a female chimpanzee named Washoe after the country in which the university is, proved to be a skillful pupil. Though there is still debate about whether what Washoe learned was really equal to human language, there is no doubt that she learned a lot of words. All of this, however, raises a second question. If Washoe can learn a complex vocabulary of gestures from people, do they have such vocabularies naturally ? To examine that possibility, Amy Pollick and Frans de Waal of Emory University have looked at gestures and expressions in chimpanzees, Signaling by facial and oral expressions is common among primates . Signaling by gestures is limited to great apes. The researchers supposed that the meaning of expressions has been fixed by evolution while the meaning of gestures is learnt. If that were true, particular sorts of facial and oral expressions would occur only in particular circumstances, and this would be the same across groups and even species. The same gestures, on the contrary, would be used in different circumstances. The researchers found exactly what they expected. Expressions almost always occurred in the same circumstances in different groups and different species. Gestures seemed to have completely different meanings.... Question: According to Pollick and Waal gestures are different from facial and oral expressions in that _ . Options: A: the meaning of facial and oral expressions can vary with circumstances. B: particular gestures occur only in particular circumstances. C: facial and oral gestures are not born but learnt. D: gestures are limited to a certain type of primates.
Answer: D

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Researchers conducting a study of hospital stays for over two hundred and eighty six thousand older folks found something interesting in their data. The number of hospitalizations for heart disease and stroke went down significantly among a certain group of people at a certain time of year. What folks, and what time of year, you ask? Flu season and the lucky people were the ones who got flu shots . It's generally recommended that people over fifty get their flu shots every year. Influenza is no small thing. it's responsible for around thirty six thousand deaths a year in the U. S. alone. Getting the shots also cuts down on the chances of getting pneumonia , which is especially dangerous in seniors. But what wasn't known was that there seems to be an added benefit to getting a flu shots in terms of _ heart problems. The data,in fact, are quite strong in suggesting this is the case. In this study, flu shots cut clown the number of hospitalizations for heart disease by nineteen percent. Stroke went down sixteen percent one season and a whopping twenty-three percent a second season.These are big results. So what's the connection between getting a flu shot and having a stronger heart? It isn't yet known. Researchers speculate that the flu virus itself may do damage to blood vessels , possibly making clots more likely. Blood clots in the heart can cause heart attacks, and blood clots in the brain can cause strokes. Whatever the specific details are, there's one more good reason to follow your doctor' s advice and get that annual flu shot. Question: According to the passage, we'd better _ . Options: A: work out to fight against influenza B: get flu shot every year C: follow our doctor's all advice D: protect our blood vessels
Answer: B

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: I have some work in Glasgow today. I was on a really tight schedule, which meant I would have no time for myself all day. I was having one of those days, the train was completely packed out and the conversation going on around me seemed to be particularly meaningless. On top of all that, I had a bit a headache. Walking quickly across the hall, I fished some change from my pocket. There was usually someone at the exit selling The Big Issue(a magazine that helps homeless folk earn a living). As the crowd parted ways at the bottom of the hall, I saw someone selling the Big Issue. You had to be homeless to sell the Big Issue. She really looked like she'd been sleeping rough. Her clothes were ragged and she was also rocking from side to side. At first I thought maybe she was trying to keep warm against the biting wind, But she wasn't ,she was moving in time to a tune. I couldn't hear her, but I could see her lips moving. As I got closer, I saw a white cane hanging from her elbow and noticed that she had sunken( ) eyes. She was blind, dirty and living on the streets. I came closer and through the noise of the traffic I heard her sing the immortal line, "--and I think to myself, what a wonderful world!" I bought her last magazine for twice what I'd originally intended. She thanked me, then she picked up her stuff and went tapping off along the pavement--still singing! So, I have my happy memory for the day. And I think it will stay with me a long ,long time. Feel free to borrow it if you like.
