(OG70)问个傻傻的阅读问题, 大家别笑我啊!!

是OG-SC里面的解释, 可我没能全懂.....

70.   A President entering the final two years of a second term is likely to be at a severe disadvantage and often unable to carry out a legislative program.

(A) likely to be at a severe disadvantage and is often unable to

(B) likely severely disadvantaged and often unable to

(C) liable to be severely disadvantaged and cannot often

(D) liable that he or she is at a severe disadvantage and cannot often（A）

(E) at a severe disadvantage, often likely to be unable that he or she can

Choice A is best. Choice B lacks the necessary infinitive after likely. In B and C, disadvantaged, which often means “hampered by substandard economic and social conditions,” is less precise than at a disadvantage. In C and D, cannot often carry out suggests that a President with limited time suffers only from an inability to achieve legislative goals frequently, not from a frequent inability to achieve them at all. In C, liable, followed by an infinitive, can legitimately be used to express probability with a bad outcome, but C is otherwise flawed as noted. D’s liable and E’s unable should be followed by an infinitive rather than by a relative clause beginning with that.

黄色部份在讲啥??能否请过路NN解一下....

不是牛牛。

cannot often carry out suggests that a President with limited time suffers only from an inability to achieve legislative goals frequently,不能经常的执行，重心在carry out说明还是执行的不过是limited 执行

原文Aoften unable to ，经常没能力执行，重心在unable to，说明就是经常没能力执行（废话一句）not from a frequent inability to achieve them at all。

cannot often carry out 强调结果,指不能常常执行

is often unable to 强调常常不能执行,强调的是常常没有能力执行,不是有限制的执行

DISCUSSION WELCOMED

be (un)able to 强调能力

can 强调可能性

呵呵...我之前就卡在这......程度上哪不同.....

请power兄指点.....
