并列結(jié)構(gòu)作主語(yǔ)時(shí)謂語(yǔ)動(dòng)詞的數(shù)

1. 由and和both...and連接的并列主語(yǔ)

此時(shí)謂語(yǔ)動(dòng)詞通常用復(fù)數(shù)。如：

Jim and Mary are both interested in it. 吉姆和瑪麗都對(duì)此感興趣。

Both brother and sister are college students. 兄妹倆都是大學(xué)生。

【注意】

(1) 當(dāng)由and連接的兩個(gè)并列主語(yǔ)受each, every, no的修飾時(shí)，謂語(yǔ)用單數(shù)：

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

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

(2) 當(dāng)and連接兩個(gè)數(shù)相加時(shí)，謂語(yǔ)動(dòng)詞可用單數(shù)或復(fù)數(shù)：

Six and eight makes [make] fourteen. 六加八等于十四。

(3) 當(dāng)and連接的兩個(gè)的詞語(yǔ)指同一個(gè)人或事物時(shí)，謂語(yǔ)通常要用單數(shù)：

A cart and horse was seen in the distance. 遠(yuǎn)處看見(jiàn)一輛馬車(chē)。

2. 由or, nor, either...or, neither…nor, not only…but also, not…but等連接的并列主語(yǔ)

此時(shí)謂語(yǔ)動(dòng)詞通常與最靠近的主語(yǔ)保持一致(即遵循就近原則)。如：

He or I am wrong. 不是他錯(cuò)了，就是我錯(cuò)了。

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

Not only the children but also the mother wants to go. 不僅孩子們想去，母親也想去。

注意這類(lèi)句型的疑問(wèn)句形式：

Were you or he there? 當(dāng)時(shí)是你還是他在那兒?

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

【注意】

在非正式文體中，個(gè)別結(jié)構(gòu)(如neither…nor)連接主語(yǔ)時(shí)，謂語(yǔ)可用復(fù)數(shù)：

Neither his father nor his mother have [has] come. 他的爸爸和媽媽都沒(méi)來(lái)。

3. 由as well as, as much as, rather than , more than, no less than 等連接的并連主語(yǔ)

此時(shí)謂語(yǔ)動(dòng)詞通常與前面一個(gè)主語(yǔ)保持一致。如：

The teacher as well as the students has read it 不僅學(xué)生讀過(guò)它，老師也讀過(guò)。

The teacher rather than the students is to blame. 應(yīng)受責(zé)備的是老師而不是學(xué)生。
