但并列主语如果指的是同一人，同一事物或同一概念，谓语动词用单数，如, His teacher and friend is a beautiful girl.
(3)、主语是单数时，尽管后面跟有as well as, but ,except, besides, with ,along with, together with, like等，谓语动词仍用单数，如，
The teacher as well as his students is excited.
(4)、某些不定代词，如做主语，谓语动词要用单数，如:Everyone has a book.
(5)、一些只有复数形式的名词，如people, cattle, clothes等作主语时，谓语动词要用复数，如，A lot of people are dancing outside.
Twenty years is not a long time.

用连词or, either……or, neither……nor, whether……or, not only…but also,等连接的并列主语，如果一个是单数，一个是复数，则谓语动词按就近一致原则，与最靠近它的主语一致，如，

例1、 The chemical works _______ where my father has worked for thirty years in 1949.
A. was built B. were built C. is built D. are built
解析：该题答案为A。works形式上是复数，意思上是单数，因此谓语动词用单数，类似的还有news, maths, politics, physics.
例2、They each _______ a copy of the new physics.
A. have B. has C. having D. gets
解析：该题答案为A。They each不等于each of …, each of 这个词组作主语谓语用单数如each of the students hands in their homework，而they each作主语，谓语要随each前面的词来变化。
