难点释疑:$lesson$
名词作主语
1、当名词词组中心词为表示度量、距离、金额、时间等复数名词时,往往可以根据意义一致的原则,把这些复数名词看作一个整体,谓语动词用单数形式。转自环 球 网 校edu24ol.com
如:Two hours is enough for me to finish the work.
两小时对我来说完成这项工作足够了。
Two hundred dollars gives Jack much help.两百美元帮了Jack大忙。
2、如果主语有more than one… 或many a…构成,尽管从意义上看是复数内容,但它的谓语动词仍然用单数形式。
如: More than one comrade has asked to stay. 不止一位同志已经要求留下。
Many a passenger was killed in the accident. 许多乘客在这一次事故中丧生。
但是“more+复数名词+than one”结构及“more than one
hundred+复数名词”结构之后,谓语动词一般用复数形式。如:
More members than one are against your plan. 不止一位成员反对你的计划。
3、不定代词each, every, no所修饰的名词及each…and each…, every…and every…, no…and
no…, many a …and many a…结构作主语时,谓语动词仍用单数形式。
如:Every man and every woman is at work. 所有男的和女的都在工作。
Many a desk and many a bench is to be taken out of the hall.
许多课桌和凳子将被搬出大厅。转自环 球 网 校edu24ol.com
4、表示成双成套的名词,如:chopsticks (筷子), compasses, clothes, glasses, jeans,
scissors, shoes, socks, trousers等,作主语时,谓语动词通常用复数形式;但如与a kind of, a pair of, the pair of, a series of 连用,作主语时,谓语动词用单数形式。
