7. 表示度量/距离/金额/时间等的名词复数作主语时的主语一致。分两种情况：若表示数值（看作一个整体），谓语用单数；若表示数量（看作多个个体的总和），谓语用复数。如， Three years has passed. Three years have passed since we met last time. Twelve is a small number. Twelve were boys. 8.不定式/动名词/从句作主语时的主谓一致。 ①单个不定式或动名词作主语，谓语用单数。两个或两个以上互不关联的事，谓语用复数。两个或两个以上密切关联为一件事，谓语用单数。如， ●To die for the people is a worthy death. ●Looking after the children is my full time job. ●When and where to hold the meeting is unknown. Playing basketball and swimming are his favorite sports.打篮球和游泳是他最爱的运动。 Going to bed early and getting up early is a good habit.早睡早起好习惯。 ②单个从句作主语时，谓语用单数。两个或两个以上，谓语用复数。由what引导的主语从句，根据整个谓语部分的意思确定谓语首词的数，因为，无法从what从句本身看出来单/复数what本身表示单数或复数意义都可以。 ●Which of them was right was quite clear to us. ●When men first made use of electricity is not exactly known. What we need is more time.（根据表语time，谓语首词用单数） What we need are doctors. （根据表语doctors，谓语首词用复数） What he says and does do not agree.他的言行不一致。（单数） What he says and does does not concern me.他的言行与我无关。（复数） ※链接：其它章节中讲到的主谓一致。1.总称名词和专有名词作主语时的主谓一致，参看第三章第三节冠词在总称名词/专有名词前的用法。2.不定代词(+of)作主语时的主谓一致，参看第四章第四节不定代词的用法总表。3.“the+形容词”作主语时的主谓一致，参看第八章第二节“the+形容词”的用法。4.定语从句的引导词作主语时的主谓一致，参看第十一章第五节.what/which/that引导的定语从句。 |
