回答下面的题目:From Ponzi to MadoffThe year was 1920.The country was the United States of America.The man’s name was Charles Ponzi.Ponzi told people to stop depositing money in a savings account.Instead,they should give it to him to save for them.Ponzi promised to pay them more than the bank.For example,a savings account might pay you$5 a year for every$1 00 you deposit.Ponzi,however,would pay you $40 a year for every $1 00 you gave him to hold.Many people thought this was a good plan.They began to give their money to Ponzi.How could Ponzi make so much money for people? This is what he did with the money people gave him:He used some of that money to pay other people who gave him money.However,he also kept a lot of the money for himself.Soon he had $250 million.This was a kind of theft,and it was against the law.The people who gave him their money didn’t think anything was wrong.Ponzi paid them every month,just like a bank.Ponzi continued this way of working for two years.Then one day,he didn’t have enough money to pay all the people.They discovered his crime,and he went to prison for froud.Ninety years later,people began to hear about a businessman in New York named Bernard Mad off.People said he gave good advice about money.They said when they gave him their money,he paid them a lot more than the bank.Mad off helped hospitals,schools,and individuals earn money.Over a period of 40 years,people gave him$1 70 billion.However,no one investigated what he did with themoney.The people who gave Mad off their money also didn’t think anything was wrong because he paid them every month.One day,Mad off didn’t have enough money to pay all the people he needed to pay.That’s when people discovered how Madoff worked:He was taking money from some people to pay other people, just the way Charles Ponzi did.However,this time,instead of losing millions of dollars,people lost billions.Madoff was accused of fraud,and United States government officials arrested him.He didn’t have to go on trial because he said he was guilty.In 2009,a judge sentenced him to 150 years in prison.Bernard Madoff’s crime was even bigger than Ponzi’s.It was the biggest fraud in history.The lesson of this story is clear:When something seems too good to be true,it probably is !For every$100 Ponzi promises to pay people__________.

回答下面的题目:Exercise Being Good or BadCan exercise be a bad thing? Sudden death during or soon after strenuous exertion on the squash court or on the army training grounds, is not unheard of. 51 trained marathon runners are not immune to fatal heart attacks. But no one knows just 52 common these sudden deaths linked to exercise are. The registration andinvestigation of such 53 is very patchy; only a national survey could determine the true 54 of sudden deaths in sports. But the climate of medical opinion is shifting in 55 of exercise, for the person recovering from a heart attack as 56 as the average lazy individual. Training can help the victim of a heart attack bylowering the 57 of oxygen the heart needs at any given level of work 58 the patient can do more before reaching the point where chest pains indicate a heart starved of oxygen. The question is, should middle-aged people, 59 .particular, be screened for signs of heart disease before 60 vigorous exercise?Most cases of sudden death in sport are caused by lethal arrhythmias in the beating of the heart, often in people 61 undiagnosed coronary heart disease. In North America 62 over 35 is advised to have a physical check-up and even an exercise electrocardiogram. The British, on the whole, think all this testing isunnecessary. Not many people die from exercise, 63 , and ECGs ( 心电图 ) are notoriously inaccurate. However, two medical cardiologists at the Victoria Infirmary in Glasgow, advocate screening by exercise ECG for people over 40, or younger people 64 at risk of developing coronary heart disease. Individuals showing a particular abnormality in their ECGs 65 , they say, a 10 to 20 times greater risk of subsequently developing signs of coronary heart disease, or of sudden death.第51题应选:
