以下是引用flywood在2004-9-3 11:41:00的发言: OG107 Downzoning, zoning that typically results in the reduction of housing density, allows for more open space in areas where little water or services exist. (A) little water or services exist (B) little water or services exists (C) few services and little water exists (D) there is little water or services available (E) there are few services and little available water 选E。
有一些关于单复数的疑问:AorB的结构,谓语不是和B保持一直吗?OG有一点解释是Since water and services are being discussed as a pair, they should logically be treated as a compound suject requiring a plural verb; thus, the singular verbs "exists" (in B and C) and "is" (in D) are wrong. 为什么这里这么解释了,不明白什么时候应该把A or B看成a pair,什么时候跟B保持一致,还有一个问题就是到底和A还是B一致,还是就是用复数呢?看过以前的贴子,未解决
A or B可以看成a pair吗?如果要看成a pair的话,是不是一定要改成and?如果还是用or 的话,是不是还是应该谓语动词与B的单复数保持一致?
问题多多!请nn们指正 |
