主語和謂語必須在人稱和數(shù)上一致:
The content of these books 1is very good .這些書的內(nèi)容很好。
Between the two buildings stands a monument .
兩座樓之間有一座紀念碑。
The results of the examination show that you have made good progress . 考試結(jié)果說明你們有很大進步。
關(guān)于這個問題,下面幾點值得注意:
1 .主語若是一個抽象概念,謂語都用單數(shù)形式:
Growing vegetables needs constant watering .種菜要經(jīng)常澆水。
Smoking cigarettes is hazardous to your health .吸煙危害健康。
2 .主語若是單數(shù),不受后面狀語的影響,謂語仍用單數(shù)形式:
Nobody but Helen and Kate was there .除了海倫和凱特那兒沒人。
No one except his parents knows anything about it . 除了他父母誰也不知此事。
3 . each 和由some , any , no , every 構(gòu)成合成代詞都作單數(shù)看待:
Each of us have something to Say .我們每人都有些話說。
Is every body ready ?大家都準備好了嗎?
4 . what , who,which 等代詞可以左單數(shù)看待,也可作復數(shù)看待,根據(jù)意思決定:which is your room ?哪是你的房間?
Which are your rooms ?哪幾間是你們的房間?
Who is knocking at the door ?誰在敲門?
Who are quarrelling ?誰在吵架?
5 . none 可作單數(shù)看待,也可作復數(shù)看待,看說話人聯(lián)想的是單數(shù)概念還是復數(shù)概念:
None ( = Not one )of us has got a camera .我們中間沒有一個人有像機。
None of these bookks arr easy enongh for us .這些書全太難,我們看不懂。
6 .有些集體名詞可追單數(shù)看待,也可作復數(shù)看待,根據(jù)意思決定:
His family isn't very large .嘶家里人不多。
His family are all music lovers .他家里人都喜歡音樂。
The committee meets twice a month .委員會一月開兩次會。
The committee are divided in opinion.委員們意見有分歧。
