3、以下名詞單復(fù)數(shù)同形:
means(手段) headquarters(司令部)
works(工廠) species(物種)aircraft(飛機(jī)) Chinese(中國人)
sheep(羊) fish(魚)
中國的計(jì)量單位:li(里), yuan(元), mu(畝)等
實(shí)例:
Every means has been tried out, but without satisfactory results. (每個方法都試過了,但結(jié)果不令人滿意。)
4、形式上是復(fù)數(shù)的學(xué)科名稱,如physics , statistics, dynamics 作單數(shù)看待;時(shí)間、距離、鈔票、重量等復(fù)數(shù),可以看作一個整體作單數(shù)處理,如:Two days is not enough for me to finish the
task. (要我完成此項(xiàng)任務(wù)兩天是不夠的。)
5、名詞做另一名詞的修飾語:
一般用單數(shù)形式,如:a college student中的college 為單數(shù)形式。
注意:
(1) 以下名詞做另一名詞修飾語時(shí)要用復(fù)數(shù)形式:sport → a sportsman (運(yùn)動員)/ sale → a sales department(銷售部) / savings → a savings account (儲蓄存款)/ communication →
a communications satellite (通訊衛(wèi)星) / greeting → a greetings cable(慰問電)
(2) 不規(guī)則名詞修飾另一名詞時(shí)數(shù)的變化:a woman doctor (一個女醫(yī)生) → two women doctors (兩個女醫(yī)生) / the Chinese women's volleyball team (中國女排) / a children
hospital (兒童醫(yī)院)
6、family(家庭), group(小組), police(警察),committee(委員會), team(組), box(盒), audience(觀眾)等詞,可以是單數(shù),也可以是復(fù)數(shù),關(guān)鍵要看題目所給的提示,例如:
The whole box of matches _____ wet; I couldn't light a simple one
A. was
B. is
C. were
D. are
解題思路:這道題如果沒有后半句I couldn't light a simple one,是沒辦法解答的。這句話提示了兩點(diǎn):
(1)時(shí)態(tài)為"過去時(shí)",故B、D已不可能了;
(2)"a simple one"說明是指盒子內(nèi)的一根根火柴,故答案為C.試想,如果我們把后半句改為 "I had to throw it away", 那么正確答案應(yīng)是A.
所以,看清題目的提示對于解題是非常重要的。
