并列结构作主语时谓语用复数_语法技巧
reading and writing are very important.
注意: 当主语由and连结时,如果它表示一个单一的概念,即指同一人或同一物时,谓语动词用单数,and 此时连接的两个词前只有一个冠词。
the iron and steel industry is very important to our life.
典型例题
the league secretary and monitor ___ asked to make a speech at the meeting.
a. is b. was c. are d. were
答案b. 注: 先从时态上考虑。这是过去发生的事情应用过去时,先排除a.,c.。本题易误选d,因为the league secretary and monitor 好象是两个人,但仔细辨别, monitor 前没有the,在中,当一人兼数职时只在第一个职务前加定冠词。后面的职务用and 相连。这样本题主语为一个人,所以应选b。
