Q: Read the article and select the best answer. Article: Young people frequently say that they want to exercise, but they just can't find the time. The solution just might be in-office interval training. Recent studies show that very short but intense exercise rapidly builds and maintains fitness and health, even when the workout is only a few minutes long. Work the stairs You can complete an excellent, effective -- and very brief -- workout in an office stairwell, says Martin Gibala, a professor of kinesiology at McMaster University in Canada and an expert on interval training. For a study that he and his colleagues presented earlier this year, they asked 12 out-of-shape women in their 20s to warm up for two minutes by slowly walking up and down stairs in a campus office building. They completed three of these abbreviated stair workouts per week for six weeks. By the end, their aerobic fitness had improved substantially, the researchers reported, by about as much as if they had been running or cycling each week for hours. Fidget your way to fitness. Parents and teachers may once have urged you to sit still, but wiggling, tapping your toes, standing briefly, and otherwise fidgeting as much as possible at your desk is in fact good for your body. In one recent study, college students showed healthier blood flow in their lower legs if they fidgeted than if they did not. Even better, a 2008 study found that among office workers, those who frequently fidgeted burned as many as 300 calories more each day than those who resolutely stayed still. Question: What does the passage mainly want to tell us? Options: A: several ways to work out within short time B: short exercise does no good to health C: how to find time to exercise D: fitness can be improved
A: A

Q: Read the article and select the best answer. Article: On Nov.18,1995,Itzhak Perlman,the violinist,came on stage to give a concert.If you have ever been to a Perlman concert,you know that getting on stage is no small achievement for him.He was stricken with polio as a child,and so he walks with the aid of two crutches. The audience sat quietly while he makes his way across the stage to his chair and begins his play.But this time,something went wrong.Just as he finished the first few bars,one of the strings on his violin broke.We thought that he would have to stop the concert.But he didn't.Instead,he waited a moment,closed his eyes and then signaled the conductor to begin again. Of course,anyone knows that it is impossible to play a pleasant work with just three strings.I know that,and you know that,but that night Itzhak Perlman refused to know that. When he finished,there was a breathtaking silence in the room.And then people rose and cheered.There was an extraordinary outburst of applause from every corner of the auditorium. He smiled,wiped the sweat from this brow and then he said-not proudly,but in a quiet,holy attitude-"You know,sometimes it is the artist's task to find out how much music you can still make with what you have left." This powerful line has stayed in my mind ever since I heard it.And who knows?Perhaps that is the meaning of life-not just for artists but for all of us. So,perhaps our task in this fastchanging,puzzling world in which we live is to make music,at first with all that we have,and then,when that is no longer possible,to make music with what we have left. Question: Why did the audience give heated claps to Itzhak Perlman? Options: A: Because they were moved by his disease. B: Because they were moved by his spirit. C: Because they were laughing at his action. D: Because they were encouraging him to cheer up.
A: B

Q: Read the article and select the best answer. Article: When I was learning calligraphy , my teacher told me a story. A calligrapher taught handwriting. One of his students who often practiced handwriting with old sheets of newspaper complained that he made very little progress though he had learned it with the calligrapher for a long time. His teacher said to him, "Try to use the best paper. Maybe you'll write better." The student did as he was told. It really worked. He made headway not long afterwards and felt curious. He asked his teacher about the reason. The calligrapher answered,"When you used old newspaper to practice handwriting, you would think you were writing a draft. It didn't matter if you wrote badly as old newspaper was plenty in supply. In that case you wouldn't pay much attention to it. Now you use the best paper and you'll treasure it. Each time you write you feel strongly about the rarity of chances and you'll devote to it with all your heart and soul; you'll do the handwriting much more attentively than practicing. Of course you've made rapid progress." Indeed, we spend our ordinary days just as they are worthless "old newspaper".We don't care if we scrawl and waste it, thinking that it will come endlessly--the "old newspaper" is inexhaustible. In such a mood we may each day pass by opportunities but fail to catch any of them. Life is not a military exercise but an actual war in which real weapons are used. In everyday life there's no chance for us to draft. That's because what we call "draft" actually is the answer sheet we write that cannot be changed. Every day of our life is something new. Let us take every day as a sheet of the best paper. Question: The calligrapher in the story told the student to write on the best paper because he thought _ . Options: A: the student would practice more carefully on the best paper B: it was comfortable to write on the best paper C: the student had enough money to buy the best paper D: the student could write more on the best paper
A: A

These units only measure quantity: they do not measure the value of the food to the body. The unit which measures the quality or value of food is the calorie the amount of heat given off by food when it brurns. This measurement tells how much energy a certain food has when it is completely used by the body. Our bodies use varying amount of calories. The more exercise we take, the more calories we burn.
