(A) If the country is to remain a leading nation in an era of international competitiveness, then new teachers must be prepared to teach their subject matter with an international orientation.
(B) If new teachers are prepared to teach their subject matter with an international orientation, then the country will remain a leading nation in an era of international competitiveness.

24. It has been claimed that an action is morally good only if it benefits another person and was performed with that intention; whereas an action that harms another person is morally bad either if such harm was intended or if reasonable forethought would have shown that the action was likely to cause harm.

Which one of the following judgments most closely confirms to the principle cited above?

(A) Pamela wrote a letter attempting to cause trouble between Edward and his friends; this action of Pamela’s was morally bad, even though the letter, in fact, had an effect directly opposite from the one intended.
(B) In order to secure a promotion, Jeffery devoted his own time to resolving a backlog of medical benefits claims; Jeffrey’s action was morally good since it alone enabled Sara’s claim to be processed in time for her to receive much-needed treatment.
(C) Intending to help her elderly neighbor by clearing his walkway after a snowstorm, Teresa inadvertently left ice on his steps; because of this exposed ice, her neighbor had a bad fall, thus showing that morally good actions can have bad consequences.
(D) Marilees, asked by a homeless man for food, gave the man her own sandwich; however, because the man tried to talk while he was eating the sandwich, it caused him to choke, and thus Marilees unintentionally performed a morally bad action.
(E) Jonathan agreed to watch his three-year-old niece while she played but, becoming engrossed in conversion, did not see her run into the street where she was hit by a bicycle; even though he intended no harm, Jonathan’s action was morally bad.

morally good, 不仅好结果，而且好动机；morally bad,结果伤害别人，无论是有意还是可以预见结果的范围内。
A、好结果，坏动机，不是morally good;
B、好结果，动机不对，不是morally good;
C、坏结果，可预见，morally bad，不是morally good;
D、坏结果，不可预见，不是morally bad;
E、坏结果，可预见，morally bad,正确。

25. Certain governments subsidize certain basic agricultural products in order to guarantee an adequate domestic production of them. But subsidies encourage more intensive farming, which eventually leads to soil exhaustion and drastically reduced yields.  
The situation above is most nearly similar to which one of the following situations with respect to the relationship between the declared intent of a government practice and a circumstance relevant to it?

(A) Certain governments subsidize theaters in order to attract foreign tourists. But tourists rarely choose a destination for the theatrical performances it has to offer.
(B) Certain governments restrict imports in order to keep domestic producers in business. But, since domestic producers do not have to face the full force of foreign competition, some domestic producers are able to earn inordinately high profits.
(C) Certain governments build strong armed forces in order to forestall armed conflict, but in order to maintain the sort of discipline and morale that keeps armed forces strong, those forces must be used in actual combat periodically.
(D) Certain governments reduce taxes on business ventures are not always as successful as their owners hoped.
(E) Certain governments pass traffic laws in order to make travel safer. But the population-driven growth in volumes of traffic often has the effect of making travel less safe despite the passage of new traffic laws

Anyone who fails to answer a patient's questions cannot be a competent physician. That is why I feel confident about my physician's competence: she carefully answers every one of my questions, no matter how trivial.
Which one of the following most closely parallels the flawed reasoning in the argument above?
(A) Anyone who grows up in a large family is accustomed to making compromises. Meredith is accustomed to making compromises, so she might have grown up in a large family.
(B) Anyone who is not in favor of this proposal is ill informed on the issue. Jeanne opposes the proposal, so she is ill informed on the issue.
(C) No one who likes music misses a performance of the symphony. Paul likes music, yet last week he missed a performance of the symphony.
(D) Anyone who works two or more jobs is unable to find a balance between professional and personal life. Maggie has only one job, so she can find a balance between her professional and personal life.
(E) No one who is hot-tempered and strong-willed will succeed in this business. Jeremy is strong-willed, so he will not succeed in this business.
能够回答病人的问题，是一个有竞争力的医生的必要条件，然而作者将它当成充分条件，所以犯了逻辑错误。
A、没有逻辑错误，大家庭长大是熟悉妥协的充分条件，熟悉妥协可能来自大家庭；
B、没有逻辑错误，不支持是被错误通知的充分条件，J反对，所以J被错误通知；
C、说的是一个例外，无关；
D、正确。前一句，从事一份工作是保持生活平衡的必要条件；后一句，将它当成充分条件；
E、暴脾气和强烈愿望共同构成无法成功的充分条件，J具有强烈愿望，无法充分说明J无法成功。
