both 和 all的用法
一、all的句法功能
all “三者或三者以上都”。具有名詞和形容詞的性質(zhì),在句中都可作主語、賓語、表語、定語和同位語。既能修飾可數(shù)名詞又能修飾不可數(shù)名詞。代替不可數(shù)名詞作主語時,謂語動詞用單數(shù)形式,代替復(fù)數(shù)可數(shù)名詞時,謂語動詞用復(fù)數(shù)。
1.作主語
All enjoyed themselves.(可數(shù)) 所有的人都玩的很開心。
Now all was changed.(不可數(shù)) 現(xiàn)在一切都改變了。
2. 作賓語
I love all.我都喜歡
3.作表語
Is that all you want to say? 你要說的就是這么一些?
二、both的用法
1.Both 可作形容詞、代詞或副詞用,意思是“兩個”、“雙方”、“兩個都”。在句中可作主語、賓語或同位語。只能修飾復(fù)數(shù)的可數(shù)名詞。作主語時謂語動詞用復(fù)數(shù)形式。
如:Both are right. 兩者都對。(主語)
I like both. 兩個我都喜歡。(賓語)
2. Both可參與構(gòu)成名詞詞組,也可和動詞連用,還可與and構(gòu)成并列連詞。在使用時,要注意下列幾點:
(1)both和all和be動詞、助動詞、情態(tài)動詞連用時,放在它們得后
面。
They are both students. 他們都是學(xué)生。
They are both working hard. 他們兩人都努力工作。
You can all go home. 你們都可以回家了。
(2)和實義動詞連用時放在實義動詞之前。如:They both ran away. 他們兩人都跑走了。
My brother and my sister both ran to help me. 我弟弟和我妹妹都跑來
幫助我。
They both like swimming .
(3)both和all跟“of 短語”連用時,后接名詞時both和all后面可以省
略of;
All (of) the students are ready for class. 所有的學(xué)生都做
好了上課準(zhǔn)備。
Both her children go to the same school. 她的兩個孩子在同一個學(xué)
校讀書。

Both his eyes were severely burned. 他的雙眼都嚴(yán)重?zé)齻恕?/p>

(4)后接代詞時,of不能省略。
例如:both (all) of后的名詞前卻一定要有定冠詞、指示代詞或物主代詞作修飾限定。Both of them are workers. 他們兩人都是工人。
Both of us thought so. 我們倆都這樣想的。
Both of them like popular songs. 他們兩人都喜歡流行歌曲。
三、both ┅and┅ 的用法
1. Both可與and構(gòu)成并列連詞,連接兩個性質(zhì)相同并在句中作相同成分的并行結(jié)構(gòu)。
如:Both he and his brother are good at English. (連接兩個主語) She can both dance and sing. (連接兩個謂語動詞)
Mary is both kind and beautiful. (連接兩個表語)
2. both┅and┅“ 兩者都┅...”,連接名詞或代詞作主語時謂語,動詞用復(fù)數(shù)形式,不受‘就近原則’的限制。如,
Both Li Ming and Wei Hua are good at English.
Both you and I are students.
3. 含both的句子變?yōu)榉穸〞r,是將both改為neither。
如:當(dāng)肯定句為Both of the boys are clever.(兩個男孩都聰明)時,
否定句當(dāng)為Neither of the boys are clever.(兩個男孩都不聰明)。Both后接復(fù)數(shù)名詞,neither后接單數(shù)名詞,動詞的人稱和數(shù)也要隨之變化。若把句子變?yōu)锽oth of the boys are not clever,則是不完全否定。意思是:并不是兩個男孩都聰明(一個聰明一個愚笨)。
4.就近原則 .
采用就近原則的情況:當(dāng)連詞或連詞短語連接兩個成分,而重點強(qiáng)調(diào)的是“其中之一”的時候,要采用就近原則。
如,or, either...or..., neither...nor..., not only...but also...等連接主語時,謂語動詞以后面的那個主語為主。
例如:
You or he is right.
Either your teacher or your classmates were there.
Neither you nor he is able to finish the work in an hour.
Not only your parents but also I am proud of you .
