Question

The central provinces have floods in some years, and _____.

A．droughts in others	B．droughts are others
C．while other droughts	D．others in droughts

Answer 1

A

试题分析：因为and 连接并列的两个宾语floods and droughts , some....others 这个是固定的搭配。如果把句子补充完整就变成：The central provinces have floods in some years, and have droughts in others.因为两个句子的谓语都是have ,用and 连接起来时的时候，可以省略后边一个相同的谓语，所以就变成了：The central provinces have floods in some years, and droughts in others.所以答案选A。
点评：在并列句中，省略是最常见的。一般说来，在后一并列句中凡是与上文相同的成分通常都要省略。My room is on the fifth floor, and hers (is) on the eighth (floor).我的房间在五楼，而她的在八楼。I came at right but Henry (came) at nine.我在八点来，但是亨利在九点来。
在简单句的并列结构中，也常采用省略的做法：You may go by land or (by) water.
你从陆路去或从水路去都可以。
