1.Five years ago, as part of a plan toencourage citizens of Levaska to increase the amount of money they put intosavings, Levaska’s government introduced special savings accounts in which upto $3,000 a yearcan be saved with no tax due on the interest unless money is withdrawn beforethe account holder reaches the age of sixty-five. Millions of dollars have accumulated in thespecial accounts, so the government’s plan is obviously working. Which of the following, if true, mostseriously weakens the argument? A. A substantial number of Levaskans havewithdrawn at least some of the money they had invested in the special accounts. B. Workers in Levaska who already save money inlong-term tax-free accounts that are offered through their workplace cannottake advantage of the special savings accounts introduced by the government. C. The rate at which interest earned on moneydeposited in regular savings accounts is taxed depends on the income bracket ofthe account holder. D. Many Levaskans who already had long-termsavings have steadily been transferring those savings into the specialaccounts. E. Many of the economists who now claim thatthe government’s plan has been successful criticized it when it was introduced. 答案是D 我选的是A：理由是，鼓励把钱存入SPECIAL ACCOUNT 就能实现PLAN，但是很多人们现在都存了进去了，可是还是要取这不就没有达到存钱的效果了么。。。不是削弱么 后来我又觉得B 对，因为大家都把钱存到WORKPLACE OFFER的FREE ACCOUNT里了，那这个SPECIAL ACCOUNT肯定就放不了了啊。。 D 怎么能是削弱啊，完全是顺着题目说的啊，把钱一点点存到SPECIAL ACCOUNT里。。
2. A study of marital relationships in which one partner's sleeping and waking cycles differ from those of the other partner reveals that such couples share fewer activities with each other and have more violent arguments than do couples in a relationship in which bother partners follow the same sleeping and waking patterns. Thus, mismatched sleeping and waking cycles can seriously jeopadize a marriage. which of the following, if true, most seriously weakens the argument above? A. married couples in which both spouses follow the same sleeping and waking patterns also occasionally have argumetns that can jeopardize the couple's marriage/ D. people in unhappy marriages have been found to express hostility by adopting a different sleeping and waking cycle from that of their spouses. 答案是D 我选的是A， 理由是原文说MISMATCHED的SLEEPING/WAKING CYCLE破坏婚姻，那只要找出别的理由也能破坏婚姻，或是MISMATCH不会破坏婚姻不就削弱了么。。所以A不正好说的是MATCH CYCLE的一对也是会破坏婚姻的，也就是说别的理由也能破坏婚姻，不就是削弱了么。。不明白为什么错。
3. A researcher discovered that people who have low levels of immune system activity tend to score much lower on tests of mental health than do people with normal or high immune system activity. The research concluded from this experiment that the immune system protects against mental illness as well as against phsical disease. The researcher's conclusion depends on whcih of the following assumptions? B. Mental illness is similar to physical disease in its effects on body systems D. mental illness does not cause people's immune system activity to decrease. 答案是D。我选的B。。。。
