大全980

980.        The Immigration Service now has the discretionary power to keep families united even though all their members do not meet the five-year residency requirement.

(A) all their members do not meet the five-year residency requirement

(B) not all their members meet the five-year residency requirement

(C) all their members have not met the requirement for a five-year residency

(D) not all their members have resided for five years, a requirement（B）

(E) all their members have not resided for five years, as required

题干的even though后面好像有全部否定的意思，答案是不是部分否定呢？

A错在哪里了呢？

不错，二者的区别就在于全部否定和部分否定；A说尽管所有成员都不符合5年居住期的要求，明显不复合原文的意思。
