啊?那版主你看Prep1里的194题: Whereas the honeybee’s stinger is heavily barbed and cannot be retracted from the skin, because the yellow jacket has a comparatively smooth stinger, it is therefore able to be pulled out and used again. A. because the yellow jacket has a comparatively smooth stinger, it is therefore able to be pulled out and used B. the comparative smoothness of the yellow jacket’s stinger allows them to pull it out and then can therefore use it C. the yellow jacket’s stinger is comparatively smooth, and can therefore be pulled out and used D. in comparison, the yellow jacket’s stinger is smooth, and thus able to be pulled out and used E. in comparison, the yellow jacket has a smooth stinger, thus allowing it to be pulled out and used 答案是C。这个and前面也没有插入语呀。。。而且考点里面说: S+V1+O1, and V2+O2.是很常见的结构. and之后的主语是S, 可是被省了. 不解啊不解~ -- by 会员 hermione0527 (2011/5/6 23:52:30)
嗯,考点里面说的不对,and前应该去掉逗号,修正为:1)S+V1+O1 and V2+O2.是很常见的结构. and之后的主语是S, 可是被省了.
通常来讲and前都是没有逗号的,看来这里我需要增加一些注释。
对于S+V1+O1, and V2+O2.结构,and前并不经常补出逗号,通常and前补出逗号是因为前面是插入语一定需要逗号,或者是为了让句子结构更为清晰,比如前面是定语从句,防止第二个谓语动词V2与定语从句中的动词并列;又比如本题的C选项加了逗号,the yellow jacket’s stinger is comparatively smooth, and can therefore be pulled out and used:used和pulled自己独自成为平行,两者组成的小团体又和前面的is平行,如果都连着写,那么会给读者一个is和used平行的印象(虽然我们并不一定会那么读,但是加了逗号更为清晰了) |
