Question: I'm taking a test and have to guess the right answer to the question after the article. Article: If you think that running marathons will help you live a long and healthy life,new research may come as a shock.According to a recent scientific study,people who do a very _ workout are as likely to die as people who do no exercise at all. Scientists in Denmark have been studying over 1,000 joggers and non-joggers for 12 years.The death rates from the sample group suggest that people who jog at a moderate pace two or three times a week for less than two and a half hours in total are least likely to die. The best speed to jog at was found to be about 5 miles per hour.The research suggests that people who jog more than three times a week or at higher speeds of over 7 mph die at the same rate as non-joggers.The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries .Over time,this can cause serious injuries. Peter Schnohr,a researcher in Copenhagen,said,"If your goal is to decrease risk of death and improve life expectancy,jogging a few times a week at a moderate pace is a good strategy .Anything more is not just unnecessary,and it may be harmful." The implications of this are that moderate forms of exercise such as tai chi,yoga and brisk walking may be better for us than "iron man" events,triathlons and long-distance running and cycling.According to Jacob Louis Marott,another researcher in the study,"You don't actually have to do that much to have a good impact on your health.And perhaps you shouldn't actually do too much". Question: What can be inferred from the text? Options: A: No exercise at all is the best choice. B: More exercise means a healthier life. C: Marathons runners are least likely to die. D: Proper exercise contributes to good health.
Answer: D

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: I have a rule for travel: Never carry a map. I prefer to ask for directions. Foreign visitors are often puzzled in Japan because most streets there don't have names. In Japan, people use _ in their directions instead of street names. For example, the Japanese will say to travelers, "Go straight down to the corner. Turn left at the big hotel and go past a fruit market. The post office is across from the bus stop." In the countryside of the American Midwest, usually there are not many landmarks. There are no mountains, so the land is very flat . In many places there are no towns or buildings within miles. Instead of landmarks, people will tell you directions and distance. In Kansas or Iowa, for example, people will say, "Go north two miles. Turn east, and then go another mile." People in Los Angeles, California, have no idea of distance on the map: They measure distance by means of time, not miles. "How far away is the post office?" you ask. "Oh," they answer, "It's about five minutes from here." You say, "Yes, but how many miles away is it?" They don't know. People in Greece sometimes do not even try to give directions because visitors seldom understand the Greek language. Instead of giving you the direction, a Greek will often say, "Follow me." Then he'll lead you through the streets of the city to the post office. Sometimes a person doesn't know the answer to your question. What happens in this situation? A New Yorker might say, "Sorry, I have no idea." But in Yucatan, Mexico, no one answers, "I don't know." People in Yucatan think that "I don't know" is impolite. They usually give an answer, often a wrong one. A visitor can get very, very lost in Yucatan! One thing will help you everywhere -- in Japan, in the United States, in Greece, in Mexico, or in any other place. You might not understand a person's words, but maybe you can understand his body language. He or she will usually turn and then point in the correct direction. Go in that direction, and you may find the post office! Question: Which of the following is WRONG? Options: A: Travelers can learn about people's customs by asking questions about directions. B: A person's body language can help you understand directions. C: People in some places give directions in miles, but people in other places give directions by means of time. D: People in different places always give directions in the same way: They use street names.
Answer: D

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: There is much discussion today about whether economic growth is desirable. At an earlier period, our desire for material wealth may have been justified. Now, however, this desire for more than we need is causing serious problems. Even though we have good intentions, we may be producing too much, too fast. Those who criticize economic growth argue that we must slow down. They believe that society is approaching certain limits on growth. These include the fixed supply of natural resources, the possible negative effects of industry on the natural environment, and the continuing increase in the world's population. As society reaches these limits, economic growth can no longer continue, and the quality of life will decrease. People who want more economic growth, on the other hand, argue that even at the present growth rate there are still many poor people in the world. These proponents of economic growth believe that only more growth can create the capital needed to improve the quality of life in the world. Furthermore, they argue that only continued growth can provide the financial resources required to protect our natural surroundings from industrialization. This debate over the desirability of continued economic growth is of vital importance to business and industry. If those who argue against economic growth are correct, the problems they mention cannot be ignored. To find a solution, economists and business community must pay attention to these problems and discuss them with one another. Question: Those who want more economic growth believe that continued economic growth _ . Options: A: is essential to the well-being of society as a whole B: can provide the solution to many of our social problems today C: can protect our environment from being polluted by industry D: can provide us with more natural resources for industrialization

A
