both的用法有兩種，它可以和名詞、代詞連用，也可以和動(dòng)詞連用，在句中作主語、賓語及同位語，也可作定語。現(xiàn)將其用法歸結(jié)如下：
◆1)both與名詞、代詞連用
(1)both+(of) +the/ 物主代詞/指示代詞+名詞，如：
①Both of the cats are asleep. 兩只貓都睡著了。
②I bought both of these bottles in China two years ago.
兩年前我在中國(guó)買了這一對(duì)瓶子。
③Both of his daughters are doctors. 他的兩個(gè)女兒都是醫(yī)生。
(2)both直接修飾名詞時(shí)，不加of。如：
①Both children won prizes. 兩個(gè)孩子都得了獎(jiǎng)。
【注意】不能說both of children，但可以說 both of the children.
②I've got oil on both hands. 我兩手都是油。
【注意】不能說both of hands，可說both of my hands。
(3)在人稱代詞前一定要用both of，不能說 both we或 both us，但可以說us both, them both等。如：
①Both of us like skating. 我們倆都喜歡滑冰。
②I want both of them. 兩個(gè)我都要。
◆2)both與動(dòng)詞連用
當(dāng)both在句中作主語的同位語時(shí)，也可與動(dòng)詞連用，both在句中的位置有以下三種情況：
(1)放在是動(dòng)詞be之后。如：
①The children are both lovely. 這兩個(gè)孩子都很可愛。
②They are both from Australia. 他們兩個(gè)都是澳大利亞人。
【注意】在感嘆句或簡(jiǎn)略答語中，both應(yīng)置于be之前。如：
③How beautiful they both are! 他們倆多漂亮啊!
④----Are you both from Japan? ----Yes, we both are.
“你們倆都是日本人嗎?”“是的，我們是?！?/p>
(2)放在行為動(dòng)詞前。如：
①We both like watching TV.我們倆都喜歡看電視。
②The men both looked French.那兩個(gè)人看起來都像是法國(guó)人。
(3)當(dāng)謂語動(dòng)詞是由幾部分組成時(shí)，both要放在第一個(gè)助動(dòng)詞后面。
如：
①We have both studied acting. 我們倆都學(xué)過演戲。
②The rooms have both been cleaned. 這兩間屋子都已打掃過了。
3)both作代詞時(shí)，可單獨(dú)使用，其后不接名詞。如：
①The brothers are good at playing basketball. Both will take part in the game.這弟兄倆人籃球打得好，他們倆都將參加比賽。
②----Which one do you want?
----I'll take both please.
“你要哪一個(gè)?”“兩個(gè)我都要?！?/p>
【注意】both與not連用，是部分否定。如：
①Both the doors are not open. 兩扇門并不都開著。
both 表示兩著都… 是個(gè)副詞,也可以做代詞,例:
副詞:We are both students.
代詞:Both of us are students.
它的否定形式是neither 詞性和both一樣,例:
副詞:We are neither STUDENT, 注意是單數(shù)名詞.
代詞:Neither of us IS a student 同樣注意也是單數(shù)
◆一、形容詞both作“兩”、“雙”解：
1.Both (the)instruments are valuable to this process.(定語)這兩個(gè)儀器對(duì)這個(gè)過程都是很有價(jià)值的。
2.Both (the)student have made a good few experiments on electricity.(定語)這兩個(gè)學(xué)生都做了不少電學(xué)實(shí)驗(yàn)。

4.He and I are both from Tianjin.(both作同位語。注意both在本句中的詞序和上兩句不同。)他和我都是天津人。
◆三、“both…and…”起連接詞作用，作“兩者都”、“又……又”、“不但……而且”解：
注意：“both…and…”能連接各種并列成分，甚至兩個(gè)句子。
1.Both copper and silver are good conductors of electricity.(連接兩個(gè)主語)銅和銀都是良好的電導(dǎo)體。

1.Both (the)instruments are not precision ones.并非這兩個(gè)儀器都是精密儀器。
2.Both of the books are not helpful.這兩本書并非都是有益的。
如果要將上述兩句改成全部否定，則就應(yīng)寫成：
1.Neither instrument is precision one.(=Either instrument is not precision one.=Either of the instruments is not precision one.)這兩個(gè)儀器都不是精密儀器。
2.Neither of the books is helpful.(=Either of the books is not helpful.=Either book is not helpful.)這兩本書都不是好書。
