1. 我們是法國(guó)人,他們是德國(guó)人。
誤:We are Frenchmen, and they are Germen.
正:We are Frenchmen, and they are Germans.
析:Frenchman(法國(guó)人)其復(fù)數(shù)形式是Frenchmen,而German(德國(guó)人)的復(fù)數(shù)形式是Germans。
。.王教授給我提了一些好建議。
誤:Professor Wang gave me some good advices.
正:Professor Wang gave me some good advice.
析:advice是不可數(shù)名詞,不可在其后加s變?yōu)閺?fù)數(shù),也不可在其前面用不定冠詞an。如說(shuō)“一項(xiàng)建議”,可說(shuō)a piece of advice.
注意:help雖然無(wú)復(fù)數(shù)形式,但常見(jiàn)有不定冠詞。如:Computer is a great help in research.
3. 我們學(xué)校有九百多孩子。
誤:There are more than nine hundreds students in our school.
正:There are more than nine hundred students in our school.
析:dozen,hundred, thousand等詞前面有數(shù)詞表示明確具體的數(shù)目時(shí),后面不管有沒(méi)有of都不用復(fù)數(shù)形式。如:
I have collected over three hundred Chinese stamps since I came here.
4. 昨天她買(mǎi)了幾十個(gè)雞蛋。
誤:She bought dozen of eggs yesterday.
正:She bought dozens of eggs yesterday.
析:當(dāng)dozen, hundred, thousand等詞的前面沒(méi)有數(shù)詞,表示籠統(tǒng)的數(shù)目時(shí),則用復(fù)數(shù)形式,后面接of,如:
Thousands of years ago, the kings of Egypt built strong tombs for themselves.
5. 她長(zhǎng)著棕色頭發(fā),藍(lán)眼睛。
誤:She has brown hairs and blue eyes.
正:She has brown hair and blue eyes.
析:hair作“毛發(fā)”總稱(chēng),是集體名詞,用作單數(shù)。但是,當(dāng)hair被看成是“毛發(fā)”總體的每一根的個(gè)體時(shí),則是可數(shù)名詞,有單數(shù)復(fù)數(shù)之分。比較:
My mother has grey hair
我母親滿(mǎn)頭白發(fā)。(頭上全是白發(fā),沒(méi)有黑發(fā))
My mother has grey hairs.
我母親有些白發(fā)。(頭發(fā)絕大多數(shù)是黑的,只有少數(shù)白發(fā))
