OG70题的OG有关C,D的错误解释不明,讨论区看过还是不明

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.

我大概译了一下,在C和D中的cannot often carry out 暗示着一个总统,他的任期的时间已经有限了,仅仅在忍受这样一种情况就是经常的没有能力达成立法的目标,      不是根本上经常的没有能力去达成目标.

1)   上面译的不是一个意思吗,我想象中应该是总统没时间实行,而不可能是没能力做,毕竟是个总统嘛,可我对答案就是区分不出来,   NN们看一下下啊.

2)    这里的not from a frequent inability to achieve them at all和 only from an inability to achieve legislative goals frequently 并列吗,那为什么中间为逗号隔开呢,不明白.

thanks

笨蚂蚁还是没明白，请NN再指点一二

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.

在C和D中,cannot often carry out暗示一个有时间限制的总统遭受着从无能到可以获得经常立法的目的,而不是从经常没有能力去做到最后根本性的获得他们.

先谢谢cocomalawi，只是不好意思的说

在C和D中,cannot often carry out暗示一个有时间限制的总统遭受着从无能到可以获得经常立法的目的,而不是从经常没有能力去做到最后根本性的获得他们.

红色的字是什么意思啊，天哪，现在英文要学，中文功底也很差啊。

cannot often carry out暗示一个有时间限制的总统遭受着经常没有能力实现立法目标而不是没有能力经常实现立法目标。

from是和suffer在一起的，不是“从”的意思

估计小蚂蚁早就明白了哈,再罗嗦一下:

often unable to carry out:常常不能完成->强调"没有能力"的频率

cannot often carry out:不能常常完成->强调"不能完成'的频率

这两个是不同的意思
