Q: I'm taking a test and have to guess the right answer to the question after the article. Article: We live in a sweet world. The average American kid eats more than 20 teaspoons of sugar per day, and adults eat 50% more sugar today than they did in the 1970s. We all know that too much sugar isn't good for you. But did we know it could be dangerous? A team of researchers at the University of Utah used mice to do a study on the bad effects of sugar. They found it could have serious effects on people's health. Sugar is found not only in sweets and candies, but also in many household items like pasta and crackers. During the 58-week-long study, mice were fed a diet containing 25% more sugar. This percentage equals a healthy human diet along with three cans of soda daily. The team found that these mice were twice as likely to die as mice fed a similar diet without the sugar. Though the mice did not show signs of obesity or high blood pressure, male mice produced 25% fewer offspring than the other mice. Scientists often use mice for research because they have a similar genetic structure to humans. "Since most substances that are dangerous in mice are also dangerous in people, it's likely that those physical problems that cause those mice to have increased deaths also work in people,"says study author James Ruff of the University of Utah. Findings from this study show bad effects that are not as noticeable as weight gain or heart problems. Sugar can contribute to long-term changes in the body that can change development and even shorten lives. Cutting sugar out of the American diet altogether may be difficult. But making the effort to control our nation's sugar need will provide for a truly sweeter future. Question: From the passage we can infer _ Options: A: sugar plays a very important role in Americans' diet B: kids eat more sugar than adults in America C: the study on human beings lasted 58 weeks D: the genetic structure of mice is totally different from that of people
A: A

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: A drunk walks into a bar and says to the waiter, "Waiter, buy everyone in the house a drink, pour yourself one, and give me the bill." So the waiter does just that and hands the man a bill for $57. The drunk says, "I haven't got it." The waiter slaps the guy around a few times, then throws him out into the street. The very next day the same drunk walks into the bar and once again says, "Waiter, buy everyone in the house a drink, pour yourself one, and give me the bill." The waiter looks at the guy and figures _ to _ himself that he can't possibly be stupid enough to play the same trick twice, so he gives him the benefit of the doubt, pours a round of drinks for the house, has a drink himself and hands the drunk a bill for $57. The drunk says, "I haven't got it." The waiter can't believe it. He picks the guy up, beats the living daylights out of him, then throws him out into the street. The next day the same drunk walks back into the same bar and says, "Waiter, buy everyone in the house a drink and give me the bill." In disgust , the waiter says, "What? No drink for me this time?" The drunk replies, "You? No way! You get too violent when you drink." Question: What can we know about the drunk from the story? Options: A: He is a rich man. B: He does it on purpose. C: He is a fool. D: He likes to drink very much.
A: D

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Welcome to the future. It's year 2050 and Scotland is now powered completely by"clean"energy. Homes have entire roofs made of solar materials, rooms are kept warm by wallpaper, and people go to and from work in electric and hydrogen( ) cars. Oil is still being found in the North Sea, but it's not now only used to keep aircraft flying. And a new 500---mile underwater link with Iceland has been built to catch heat from the hot springs. There's still a role for king coal--but _ are now environment---friendly. People will be able to import the electricity they need and export any excess they make through rooftop windmills . New technology will store electricity better and provide it on demand. Heat exchangers will provide heating and hot water. Harmful carbon dioxide waste is being piped offshore to St Fergus and from there into some of the remaining oil--producing fields to be stored safely without entering the atmosphere. Gas remains the preferred energy source of industry and is now shipped in liquid form. But hydrogen is imported through pipelines from France and from a geothermal plant in Iceland. Hydrogen--fuelled cars have become popular. Electric bikes are common in cities using the new urban two--wheel network. Electric vehicles have become common, and their performances have been improved because of the developments in electrical drive technology like high--temperature super conducting motors. Many people leave their vehicles in a giant park where they can be recharged from the national electrical system . Oilseed rape is widely grown to fuel some motors . Question: Which sources of energy play a more important role in people's daily life in the future ? Options: A: Oil and coal B: Hydrogen and gas C: Electricity and gas D: Solar energy and wind
A: D

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Animals seem to have the sense to eat when they are hungry and they do not eat more than their bodies need. It has been demonstrated that rats will, when given a choice over a period of time, prefer water with vitamins to water without vitamins even though there is no difference in taste or smell between the two water bottles. When a fragrant flavor was added to the vitamin-enriched water, the rats did seem to prefer it and kept drinking it ,even after the vitamins were switched to the clear water. In time, however, they broke _ and went back to where the necessary vitamins were. In a classic experiment, babies of 6 to 12 months old were placed in a cafeteria feeding arrangement, with a wide selection of baby food before them. They were given whatever food they pointed to or appeared interested in. We are told that at first they showed some unusual eating patterns, but that over a period of time they managed to select well-balanced diet. So, in selecting food, rats and babies do seem to know and act on what's best for them. Apparently, there is a kind of "body wisdom", which humans soon lose. Most of us do not eat as wisely as we could. Many of our food preferences are culturally determined and influenced by long-established habits. Some people eat fox, dog and blackbirds, while we eat cows and pigs. So what people eat and how much they eat seems to be greatly influenced by what is going on around them. Question: As far as their eating habits are concerned, babies and rats are similar in that _ . Options: A: both have the wisdom to choose a balanced diet B: both prefer flavored food and drink C: both have the same eating patterns D: both develop a taste for the same kinds of flavors
A: A
