當并列結構作主語時主謂一致的用法

1. 由and和both...and連接的并列成分作主語時，其謂語動詞通常要用復數。如：

Christianity and Islam are two different religions. 基督教與伊斯蘭教是兩種不同宗教。

Both handle and bolt are automatically deadlocked against turning. 把手和插梢都自動鎖死不能轉動的。

注：當由and連接的兩個并列主語受each, every, no的修飾時，謂語用單數。如：

Every boy and (every) girl likes the book. 每個男孩女孩都喜歡這本書。

No desk and (no) chair was seen in the room. 房間里不見桌椅。

2. 由or, nor, either...or, neither…nor, not only…but also, not…but等連接的并列成作主語時，謂語動詞通常與最靠近的主語保持一致(即遵循就近原則)。如：

He or I am wrong. 不是他錯了，就是我錯了。

Either you or he has taken it. 不是你拿了就是他拿了。

Not only the students but also the teacher wants to go. 不僅學生想去，老師也想去。

注意這類句型的疑問句形式：

Were you or he there? 當時是你還是他在那兒?

Are either you or he to blame? 是怪你還是怪他?

注：在非正式文體中，個別結構(如neither…nor)連接主語時，謂語可用復數。如：

Neither his father nor his mother have [has] come. 他的爸爸和媽媽都沒來。

3. 由as well as, as much as, rather than , more than, no less than 等連接的并列成分作主語時，謂語動詞通常與前面一個主語保持一致。如：

The teacher as well as the students has read it 不僅學生讀過它，老師也讀過。

The teacher rather than the students is to blame. 應受責備的是老師而不是學生。
