题目

In China ,when people meet you for the first time,he or she always __________（握,摇）hands with y
In China ,when people meet you for the first time,he or she always __________（握,摇）hands with you warmly.
这个题是填shake还是shakes?为什么?

答案

shakes
主句的主语是并列主语he or she,用or连接的主语,谓语动词【就近一致】,随she变化,因为she是单数第三人称,所以答案是 shakes
