职称英语常用语法详解3
作者:网友提供 来源:启德考培 时间:2020-02-04
B. aren't many furnitures
C. hasn't much furniture
D. isn't enough furniture
解题思路:根据名词数的概念A、B肯定错,不必考虑;C、D的主要差异是"hasn't"与 "isn't", 句子中有there,说明该句是there be句型,故正确答案为D.题中staff, office 等词与解题无关。
注意辨别句子中斜体词的数及其意义:
There is still much room for improvement. (仍有许多改进的余地)
He has published two important papers on this subject. (他在这个课题上已发表了两篇重要论文。)
3、以下名词单复数同形:
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
