主謂一致是一個(gè)很重要的語(yǔ)法項(xiàng)目,以下這些重要的問(wèn)題要注意,否則易在英語(yǔ)學(xué)習(xí)中出現(xiàn)錯(cuò)誤。
1.many a+單數(shù)名詞作主語(yǔ),意義雖為“許多”,但謂語(yǔ)要用單數(shù)形式。
如:Many a student has been to Japan before.(很多學(xué)生去過(guò)日本。)
2.某些復(fù)數(shù)名詞如:shoes,glasses,trousers,scissors等作主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞用復(fù)數(shù)形式,但如果前面有量詞出現(xiàn),則謂語(yǔ)動(dòng)詞要用單數(shù)形式。
如:The trousers there are expensive.(那的褲子很貴。)
3.當(dāng)主語(yǔ)中包括with,along with,as well as,together with,besides,except,but,including等時(shí),謂語(yǔ)動(dòng)詞和這些詞前面的主語(yǔ)保持一致。
如:Tom,together with his family is going on holiday.(湯姆和他的家人一起去度假。)
4.時(shí)間、距離、金錢、重量等作主語(yǔ)時(shí),看作一個(gè)整體,謂語(yǔ)用單數(shù)形式。
如:Five dollars is enough.(五美元就足夠了。)
5.由what引導(dǎo)的名詞性從句作主語(yǔ)時(shí),謂語(yǔ)用單數(shù)形式。
如:What they said is right.(他們所說(shuō)的是正確的。)
6.固定結(jié)構(gòu)each+單數(shù)名詞+and、each+單數(shù)名詞或every+單數(shù)名詞+and、every+單數(shù)名詞,謂語(yǔ)動(dòng)詞用單數(shù)。
如:Each boy and each girl has got a seat.(每個(gè)男孩和女孩都有座位了。)
7.a number of作主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞用復(fù)數(shù)形式;the number of作主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞用單數(shù)形式。
如:A number of people are trying to learn English. (很多人在努力學(xué)英語(yǔ)。)
8.動(dòng)詞不定式或動(dòng)名詞在句中作主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞用單數(shù)形式。
