摘要:并列结构作主语时谓语用复数.例如: Reading and writing are very important. 读写很重要. 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.例如: The iron and steel industry is very important to our life. 钢铁工业对我们的生活有重要意义. 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.
