  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 1 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。
