- he is going to spend more time on American English

Read the following article and answer the question. Article: Englishmen speak British English and Americans speak American English. A student is learning to speak British English. He often asks himself, "Can Americans understand me when I speak British English?" Learners often ask "What's the difference between British English and American English?"Certainly there are some differences between British and American English. The Englishmen say "Have you a pen?" While Americans say "Do you have a pen?" The pronunciation is sometimes different. Americans often sound "r" in words like "bird" and "hurt". The British speakers don't sound the "r" in these words. There are differences in spelling. For example, "colour" and "neighbour" are British while "color" and "neighbor" are American. These differences in grammar, pronunciation and spelling are not important, however. For the most part, British and American English are the same language. When Englishmen and Americans are talking with each other, they don't need an interpreter . Maybe some day they need, but not now. Question: When a student is asking himself "Can Americans understand me when I speak British English?" it shows that   _   . Answer:
****
A: he hasn't spoken to any American so far


Problem:OPTIONS:
- They are too slim
- They work too hard
- They are too fat
- They lose too much body fat.

Read the following article and answer the question. Article: In the United States, 30 percent of the adult population has a "weight problem.". To many people, the cause is clear: We eat too much. But scientific evidence does little to support this idea. Going back to the America of 1910, we find that people were slimmer than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn't watch television. Several modern studies, moreover, have shown that fatter people don't eat more on average than thinner people. In fact, some investigations (researches), such as a 1970 study of 3,545 London office workers, report that, on balance, fat people eat less than slimmer people. Studies show that slim people are more active than fat people. A study by a research group at Stanford University School of Medicine found the following interesting facts. The more the men ran, the greater loss of body fat. The more they ran, the greater their increase in food intake .  Thus those who ran the most ate the most, yet lost greatest amount of body fat. Question: What kind of physical problem do many adult Americans have? Answer:
****
A: They are too fat


Problem:OPTIONS:
- cause little harm to the ocean life
- are more environmentally friendly
- change the course of ocean currents
- are easy to build in large quantities

Read the following article and answer the question. Article: Microsoft just finished a three-month experiment operating an underwater data center.A server rack  with the power of about 300PCs was placed into a water-tight  steel container and lowered into the ocean off the coast of central California. The unusual experiment was launched because current data centers are unpleasantly inefficient.They're built where energy and land are cheap (not close to where people actually live).And they waste so much energy cooling their massive computers.The ocean can solve those problems.The cold ocean floor sufficiently cools the computing components inside the pod.And since most people live near the ocean,placing data centers under water could potentially increase the speed at which customers could access the information stored in Microsoft's cloud. The experiment was so successful that Microsoft operated the underwater data center for 75days longer than it had planned to.The next step is to get a larger pod,with about four times the computing power,under the ocean for testing.Unlike the first experiment,the next pod will also be equipped with turbines,which will transform the ocean's currents into electricity.It's not clear when,if ever,underwater data centers will become a possible product."Our first experiment was like dipping our pinkie toe in the water,and now we're going for the big toe,"said Lee,corporate vice president of Microsoft Research. Microsoft is still analyzing the environmental impacts of the study.Data centers are both hot and loud,which could have damaging effects on ocean life.Microsoft found that the noise its underwater data center produced was drowned out by nearby shrimp and crabs.The data centers are also built from recyclable materials,and Microsoft believes that the total carbon footprint of underwater data centers will be"dramatically lower"than current land-based centers. Given the growth in the cloud,industry analysts believe that most of the world's data centers have yet to be built.But building a data center takes at least two years-an  eternity... Question: We can infer that the underwater data centers   . Answer:
****
A: are more environmentally friendly


Problem:OPTIONS:
- turn out to do better in their studies
- prefer to share food with others

- are interested in cooking

Read the following article and answer the question. Article: When was the last time your family sat down together to have a dinner? The speed at which we live today no longer allows for slow eating habits. Most people work long hours. There is lots of fast food and eating out is now on the increase. Often, food is eaten in front of the television in silence, or a child eats alone in front of the computer. When I was a child, every evening around the same time, one of the children would be asked to set the table, and then we'd go and wash our hands: before the meal. This was the time of day when we would talk about our day at school. But now things have changed a lot. A family environment plays an important role for children in learning to communicate with others and understanding table manners, such as waiting for others to finish before leaving the table and not speaking with a mouth full of food. Parents' likes and dislikes of a certain food will also influence a child's own likes and dislikes. Studies have shown that children who often eat with their families have better results at school than children who eat with their families less than twice a week. Regular meal times give children the chance to discuss their problems with family members. They can also learn to respect others around the table. Talking to your children over dinner is the best way of having their-trust. Children learn good eating habits from their parents at a very young age. Family meals are important. Prepare them for your children. Question: Children who often eat with their families   _  . Answer:
****
A:
Answer: turn out to do better in their studies
