并列结构作主语时谓语用复数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,在英语中,当一人兼数职时只在遥个职务前加定冠词。
后面的职务用and 相连。
这样本题主语为一个人,所以应选B。
