完成下列各题 B
The human body naturally prevents attempt(企图)to lose or gain weight.Thus the best way to lower your weight is to do some exercise daily.Although scientists don’t agree exactly how this works to lower the“setpoint”,they do know that exercise helps your body work with you and not against you in at least the following ways: 1.Exercise burns calories(卡路里):if you walk two miles every day,you use an extra 1400 calories a week—and lose about a pound in two weeks. 2.Exercise helps to bum fat and build muscle:since muscle requires more calories than fat does,the more muscle you have,the faster you will bum calories. 3.Finally exercise speeds up your metabolism(新陈代谢),not just while you’re exercising,but for several hours after exercise ends. A program of light-to-moderate exercise done for only a half-hour a day is enough to keep your“setpoint”lowered,and thus helps you lose weight and keep it off.If you need to lose more than five pounds,combine regular exercise with a moderate reduction in calories until you reach your goal(目标). Scientists don’t________.
A.think exercise helps peoples bodies work against them
B.agree exercise helps to lower peoples weight
C.bilieve in exercise at all
D.think exercise helps peoples bodies work with them

完成下列各题 A Eating disorders(混乱)is very common now.“When I first wrote about this,the problem was pretty much hidden…I didn’t expect ii to get:as bad as it is,”Susie Orbach,all intema’tional authority(权威)on eating disorders,said. Orbach must at times think the anti-diet message of her book“Fat is a Feminist(女权主义的)Issue(问题)”has been lost since it was written more than 20 years ago. Girls,boys,old people-even the famously well-rounded female(女性)population of Fiji is failing victim(牺牲品)to fat fears."If anything.the situation has got much,much worse.We nOW have kids as young aseight and women in old people’s homes worried about the way they look," Orbach said. Even though it has been proved that repeated dieting results in a little more than regaining most of the lost weight, constant dieting(节食)has become a way of life for many women.48 per cent of British women aged 25 t0 35 were on some kind of diet and that 20 per cent of young wonen dieted all or most of time.Some of them said they would pop a pill to give them their beautiful shape.even if it meant risking their health. Worldwide,70 million people have an eating disorder.Most are women,but men are increasingly affected,too. More than half the women and two-thirds of the men in Britain weigh too much,while in the United States more than one quarter of adults and about one in five children are overweight.The idea that female beauty is a very thin body could be changed,if clothing factories and magazines showed images(形象)of women of an shapes instead of selecting skeletal-like models and stick.thin actresses. But that is easier said than done. To get her message across.Orbach is also considering talking to pop stars such as Victoria Beckham and Geri Halliwell,both of whom have admitted(承认)having suffered from eating disorders. According to Susie Orbach,________.
A.nobody had suffered from eating disorders 20 years before
B.eating disorders had become much commoner than before
C.eating disorders shouldn’t have become so common as it was
D.Victoria Beckham and Geri Halliwell hadn’t suffered from eating disorders
A.nearly nine kilometres deep
B.almost eleven kilometres high
C.two kilometres above the highest mountain in the world
D.two kilometres deeper than the height of the world's highest mountain
请根据以下内容回答下列各题 Insurance (保险)is the sharing of risks. Nearly everyone isexposed to risk of some sort. The house owner, for example, knows that hisproperty can be damaged by fire; the ship-owner knows that his vessel may belost at sea; the breadwinner knows that he may die at any early age and leavehis family poorer. On the other hand, not every house is damaged by fire norevery vessel lost at sea. If these persons, each put a small sum into a pool,there will be enough to meet the needs of the few who do suffer loss. In otherwords, the losses of the few are met from the contributions of the many. Thisis the basis of insurance. Those who pay the contribution are known as insuredand those who administer(管理)the pool of contributionsas insurers. The legal basis of all insurance is thepolicy. This is a printed form. of contract on stout paper of the best quality.It states that in return for the regular payment by the insured of a named sumof money, called the pre- mium(保险费), which is usually paid every year, the insurer will pay a sum ofmoney or compensation for loss, if the risk or event insured against actuallyhappens. The premium for an insurance naturally depends upon how likely therisk is to happen, as suggested by past experience, ff companies fix theirpremiums too high, there will be more to make the premium too low, they willlose money and may even have to drop out of busi- ness. So the ordinary forcesof supply and demand keep premiums at a level satisfactory to both the insurerand the insured. According to the writer, insurance is possible because__________
A.only a small proportion of the insured sufferloss
B.only insured people suffer loss
C.nearly everyone suffers loss
D.everyone at some time suffers loss
