The higher the level of certain vitamins and minerals inthe bloodstream, the better a person's lung function, as measured by the amountof air the person can expel in one second. The lung function of smokers is significantly worse, on average, thanthat of nonsmokers. Clearly, therefore,one way for smokers to improve their lung function is for them to increasetheir intake of foods that are rich in these helpful vitamins and minerals.

  Which of the following is an assumption on which thisargument depends?

  (A) Smokers are less likely than nonsmokers to have dietsthat are rich in vitamins and minerals.

  (B) The lung function of smokers whose diets are rich inthose vitamins and minerals is generally better than that of nonsmokers withcomparable diets.

  (C) People whose diets are deficient in those vitaminsand minerals do not typically have other health problems in addition todiminished lung function.

  (D) Stopping smoking will not typically improve lungfunction more than any diet changes can.

  (E) Smoking does not introduce into the body chemicalsthat prevent the helpful vitamins and minerals from entering the bloodstream.

  “When someone achieves greatness in any field — such as the arts, science, politics, or business — that person’s achievements are more important than any of his or her personal faults.”


  1,Every one has faults. We can not ignore one's achievement only because he or she has made some faults. Likewise, we can not neglect one's error when he or she achieves greatness in the field.

  2,When it comes to which one is more important, the greatness or the faults, the final judgement should be based on the situation of the certain person. In fact, as far as I am concerned, it makes no sense to make such a judgement.

  3,We should give a person fair and reasonable evalluation. It is imprudent轻率的 to say that the greatness one achieves in one field is necessarily more important than the faults he or she makes.

  衡量人们的成就与错误的重要性,本身一直是一个controversial topic。

  1,The proponents of this view may argue that 人们不能因为过错而忽视成就。在很多情况下,compared with the huge achievements, those great people’s faults appear so unimportant as to be forget. 比如,Yet even a cursory review of the private lives of past Presidents reveals substantial evidence that Franklin Roosevelt, Dwight Eisenhower, Lyndon Johnson and John Kennedy had extramarital affairs. Thomas Jefferson, many believe, fathered children by one of his slaves. And Grover Cleveland confessed to having an illegitimate child.但与他们的政治成就相比,比如Roosevelt boosted the American economy and cease the recession…人们往往选择neglect such faults.

  2,以上的观点,不代表说,我们可以因为一个人的成就,而忽视他的重大过错。比如Mao, who released Chinese from the aggression of other nations, and also, who started the “Great culture revolution” in China which brought huge disaster to hundreds and thousands of innocent people. Poet named “Haizi” who is highly achieved in arts and literature, murdered his wife and then committed suicide. It is unfair to take it for granted that any achievement in any field is more important than life.

  3,所以,在很多情况下,成就与过错的重要性随情况变化而变化,没有一个perpetual right answer to this question. 我认为就这个问题本身的讨论并没有意义,评价一个人的时候,应该collectively and objectively evaluate a person by considering both the faults and the achievements rather than by claiming one of the two is more important than the other.
