(二)並列結構作主語時的情況

字體:16+-

1.由and 連接的兩個單數名詞作主語時,謂語動詞一般根據意義一致的原則用複數。如:

July and August are the hottest months in Beijing.

七月和八月是北京最熱的月份。

The black and the white dog are always barking.

那條黑狗和白狗總是叫個不停。(當and所連接的兩個名詞相同而修飾詞不同時,第一個名詞通常省略,而謂語動詞用複數)

注意:但如果在意義上指同一個人、同一件事或同一個概念時,謂語動詞要用單數形式。如:

A needle and thread was found on the floor.

在地板上找到了針線。(穿了線的針)

The poet and writer has come.

那位詩人兼作家來了。(同一個人,既是詩人又是作家)

2.當each…and(each)…,every…and(every)…,no…and(no)…,many a…and(many a)…結構作主語時,謂語動詞用單數形式。如:

Every boy and every girl is treated in the same way.

每個男孩和女孩都受到同樣對待。

Many a teacher and student has seen the film.

許多老師和學生看過這部電影。

No desk and(no)chair was in the room.房間裏沒有書桌和椅子。

3.由not only…but also…,either…or…,neither…nor…,…or…,not…but…連接的並列主語,以及在there be結構有and連接的並列主語時,謂語動詞通常依就近一致原則決定。如:

Were you or he on duty?你還是他值日?

Neither her brother nor her parents were in favor of her marriage.

她哥哥和她父母都不讚成她的婚姻。

Not only she but also I am tired.不但她很累,我也很累。

There is a pen,a knife and several books on the desk.

桌上有一支鋼筆,一把小刀和幾本書。

4.當主語由as well as,with,along with,together with,rather than,no less than,but,except,besides,in addition to,like,including等詞連接時,其謂語動詞的單複數形式通常由前麵的詞來決定。如:
