注意: 當(dāng)主語由and連結(jié)時,如果它表示一個單一的概念,即指同一人或同一物時,謂語動詞用單數(shù),and 此時連接的兩個詞前只有一個冠詞.

The iron and steel industry is very important to our life.

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: 先從時態(tài)上考慮.這是過去發(fā)生的事情應(yīng)用過去時,先排除A.,C..本題易誤選D,因為The League secretary and monitor 好象是兩個人,但仔細辨別, monitor 前沒有the,在英語中,當(dāng)一人兼數(shù)職時只在第一個職務(wù)前加定冠詞.后面的職務(wù)用and 相連.這樣本題主語為一個人,所以應(yīng)選B.
