请教OG 70

70. A President entering the final two years of a second term is likely to be at a severe disadvantage and is 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

(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.

为什么不是C呢？我记得有书上说be unable to do是能力的意思，就是没有能力，can not 是可能性的意思，就是没有可能，我觉得应该是总统剩下的2年时间不够，所以不可能完成立法程序，而不是没有能力完成立法程序啊？不明白了，怎么总统有时间就有能力完成，没有时间连能力都没有了？

    不要以一个知识点而判断一个选项，把握整体的意思的基础上，寻找多个判断点

    OG说了，be severely disadvantaged 的意思和 be at a severe disadvantage 不一样；cannot often和often unable to意思又不同

    你说的能力和可能的原则，我也听说过，可能是LZM或者XDF说的，但是我不觉得这个原则有多正确有多有用

    你可以去搜索一下大全题目，没有一个题目会孤立的考can和be able to的区别

    一点个人意见

   

Judye

can 和 be able to 是有区别的。但是抓错应该从主要的错误开刀。be severely disadvantaged 完全改变了原文的逻辑涵义。

我的问题是 liable 应该怎么用。这个词的含义也表示 “可能” 吗？  是不是 be liable to do?还是  be liable that?

dreadpower

     

be liable to do sth (be likely to do or say sth especially because of a fault or natural tendency)

be liable for sth  :  manufactures are liable for any defects in the equipment

tianwan

be liable to do sth, be liable to sth, be liable for sth可以，be liable that不可以。

be like to do， it is likely that可以。

非常感谢

看来是不能用can>ba able to

做题了

be severely disadvantaged 的意思和 be at a severe disadvantage 的意思请哪位具体解释一下区别呢？

wildwind

以OG 为准,

disadvantaged, which often means “hampered by substandard economic and social conditions

经济条件差的, 社会地位低下的

disadvantage,  劣势, 不利之处

我还想就这个问题请问:be liable to do 和be likely to do 有区别,在这一题中是否两者都可以接受?

谢谢NNs!
