四级语法与词汇（7）
1. For some time now, world leaders ____ out the necessity for agreement on arms reduction. A. had been pointing B. have been pointing C. were pointing D. pointed
参考答案： B
TIP：本句的时间状语是for some time now，既表示过去到现在的一段时间，又包括现阶段，所以应选用现在完成进行时。本句意为：一段时间以来，世界各国的领导们一直在指出有必要就武器削减问题达成共识。
2. Being color-blind, Sally can't make a ____ between red and green. A. difference B. distinction C. comparison D. division
参考答案： B TIP：make a distinction between表示“区分，对两者加以区别”。而make a difference between意为“对??加以区分对待”，例如：She makes a difference between her own child and her stepchild. make a comparison between表示“对??加以比较”，separation和division意为“分开”，不用于此结构。
3. The new colleague ____ to have worked in several big corporations before he joined our company. A. confesses B. declares C. claims D. confirms
参考答案： C
TIP：claim后接不定式表示“声称”，不定式的动作如果在claim之前发生则应使用不定式的完成时。confess表示“坦白，承认”，一般后接一些不好的事。declare表示“宣布，声明”，后面不接不定式。confirm表示“确认，证实”，之后也不用不定式。
4. The student said there were a few points in the essay he ____ impossible to comprehend. A. has found B. was finding C. would find
D. had found
参考答案： D

5. All of us would have enjoyed the party much more if there ____ quite such a crowd of people. A. hadn't been B. weren't C. hasn't been D. wouldn't be
参考答案： A
TIP：根据此句的主句，可以判断从句是与过去事实相反的虚拟语气，故从句使用过去完成时。

参考答案： D
TIP：accidentally意为“偶然地，意外地”；incidentally意为“附带地，顺便提及”；eventually意为“最后，终于”；naturally意为“自然地”。本句译为：我该走了，顺便提一句，如果你要那本书，我下次带来。
