有些知识点是翻来覆去的经常考的,因为考纲就是那么一个,能不重复考吗,所以,小编收集了一些考试真题,与大家分享,但愿能起到温故而知新的效果:

解析:A。句意:一位诗人兼艺术家明天下午要给我们做关于中国文学和绘画的报告。该题由and连接两个名词作主语,但第二个名词前没有冠词,因此指的是同一人,故谓语用单数形式。注意:由and连接的两个带冠词单数名词,表示复数概念时,谓语动词用复数形式。如: The tenth and the last chapter were written by his father.
【考例2】

考点二、谓语动词的形式与邻近的名词一致
(一) either…or…/neither…nor…/not only…but also…/not…but…/or等连接并列主语时,谓语动词单复数由最靠近它的主语决定;
(二)在倒装句中,谓语动词单复数由其后面的主语决定。
【考例1】

A. are being built B. were being built
