卫生类辅导资料:语法巩固复名词单复数同形
means(手段) headquarters(司令部)
works(工厂) species(物种)
aircraft(飞机) Chinese(中国人)
sheep(羊) fish(鱼)
中国的计量单位:li(里), yuan(元), mu(亩)等
实例:
Every means has been tried out, but without satisfactory results. (每个方法都试过了,但结果不令人满意。)
4、形式上是复数的学科名称 如physics , statistics, dynamics 作单数看待;时间、距离、钞票、重量等复数,可以看作一个整体作单数处理,如:Two days is not enough for me to finish the task. (要我完成此项任务两天是不够的。)
5、名词做另一名词的修饰语:
一般用单数形式,如:a college student中的college 为单数形式。
注意:
(1) 以下名词做另一名词修饰语时要用复数形式:sport → a sportsman (运动员)/ sale → a sales department(销售部) / savings → a savings account (储蓄存款)/ communication →
a communications satellite (通讯卫星) / greeting → a greetings cable(慰问电)
(2) 不规则名词修饰另一名词时数的变化:a woman doctor (一个女医生) → two women doctors (两个女医生) / the Chinese womens volleyball team (中国女排) / a children
hospital (儿童医院)
6、family(家庭), group(小组), police(警察),committee(委员会), team(组), box(盒), audience(观众)等词,可以是单数,也可以是复数,关键要看题目所给的提示,例如:
The whole box of matches _____ wet; I couldnt light a simple one
A. was
B. is
C. were
D. are
解题思路:这道题如果没有后半句I couldnt light a simple one,是没办法解答的。这句话提示了两点:
(1)时态为“过去时”,故B、D已不可能了;
(2)“a simple one”说明是指盒子内的一根根火柴,故答案为C.试想,如果我们把后半句改为 “I had to throw it away”, 那么正确答案应是A.所以,看清题目的提示对于解题是非常重要的。
