3."both”的用法和位置

用法有两种,它可以和名词、代词连用,也可以和动词连用,在句中作主语、宾语及同位语,也可作定语。

现将其用法归结如下: 1)both与名词、代词连用 (1)both+(of) +the/ 物主代词/指示代词+名词,如: ①Both of the cats are asleep. 两只猫都睡着了。 ②I bought both of these bottles in China two years ago. 两年前我在中国买了这一对瓶子。

③Both of his daughters are doctors. 他的两个女儿都是医生。 (2)both直接修饰名词时,不加of。

如: ①Both children won prizes. 两个孩子都得了奖。 【注意】不能说both of children,但可以说 both of the children. ②I've got oil on both hands. 我两手都是油。

【注意】不能说both of hands,可说both of my hands。 (3)在人称代词前一定要用both of,不能说 both we或 both us,但可以说us both, them both等。

如: ①Both of us like skating. 我们俩都喜欢滑冰。 ②I want both of them. 两个我都要。

2)both与动词连用 当both在句中作主语的同位语时,也可与动词连用,both在句中的位置有以下三种情况: (1)放在是动词be之后。如: ①The children are both lovely. 这两个孩子都很可爱。

②They are both from Australia. 他们两个都是澳大利亚人。 【注意】在感叹句或简略答语中,both应置于be之前。

如: ③How beautiful they both are! 他们俩多漂亮啊! ④----Are you both from Japan? ----Yes, we both are. “你们俩都是日本人吗?”“是的,我们是。” (2)放在行为动词前。

如: ①We both like watching TV.我们俩都喜欢看电视。 ②The men both looked French.那两个人看起来都像是法国人。

(3)当谓语动词是由几部分组成时,both要放在第一个助动词后面。 如: ①We have both studied acting. 我们俩都学过演戏。

②The rooms have both been cleaned. 这两间屋子都已打扫过了。 3)both作代词时,可单独使用,其后不接名词。

如: ①The brothers are good at playing basketball. Both will take part in the game.这弟兄俩人篮球打得好,他们俩都将参加比赛。 ②----Which one do you want? ----I'll take both please. “你要哪一个?”“两个我都要。”

【注意】both与not连用,是部分否定。如: ①Both the doors are not open. 两扇门并不都开着。

====================================================== both 表示两着都… 是个副词,也可以做代词,例: 副词:We are both students. 代词:Both of us are students. 它的否定形式是neither 词性和both一样,例: 副词:We are neither STUDENT, 注意是单数名词. 代词:Neither of us IS a student 同样注意也是单数 ========================================================= Both的用法及注意事项 一、形容词both作“两”、“双”解: 1.Both (the)instruments are valuable to this process.(定语)这两个仪器对这个过程都是很有价值的。 2.Both (the)student have made a good few experiments on electricity.(定语)这两个学生都做了不少电学实验。

二、代词both作“两人”、“两者”解: 1.Bothe (of them)have been to Beijing.(主语)他们两人都去过北京。 2.There are two English books on the table. He wants to read them both in a short time.(同位语)桌上有两本英语书,他想在短时期内阅读这两本书。

3.Steel and petroleum both play an important part in the development of industry and agriculture.(同位语)钢和石油这两样东西在工农业发展中起着重要作用。 4.He and I are both from Tianjin.(both作同位语。

注意both在本句中的词序和上两句不同。)他和我都是天津人。

三、“both…and…”起连接词作用,作“两者都”、“又……又”、“不但……而且”解: 注意:“both…and…”能连接各种并列成分,甚至两个句子。 1.Both copper and silver are good conductors of electricity.(连接两个主语)铜和银都是良好的电导体。

2.The molecules of common salt all contain atoms of both the gas and the metal which compose the salt.(连接of的两个宾语)食盐分子都具有构成食盐的气体和金属这两种物质的原子。 3.Alloys are both useful and important.(连接两个表语)合金既有用又重要。

4.To do work, you must both exert force and move something.(连接两个动词短语)为了作功,你必须既施加力又推动某个东西。 5.Copper is an important conductor, both because of its high conductivity and because of its abundance and low cost.(连接两个状语)铜是一种重要的导体,因为它的导电率高,而且资源丰富,价格又低。

6.It is necessary to build a lot of petrochemical works, both because China is rich in petroleum and because there is a great demand for petrochemicals.(连接两个状语从句)由于中国石油丰富,而对石油化学产品需要量又大,所以有必要建立许多石油化工厂。 四、注意“both+否定式谓语+…”构成部分否定: 1.Both (the)instruments are not precision ones.并非这两个仪器都是精密仪器。

2.Both of the books are not helpful.这两本书并非都是有益的。 如果要将上述两句改成全部否定,。

4.求解both用法 详细

要知道用法,首先要弄清楚词性和相对应的词义

形容词:二者,两者都,与副词一样多用于句型中表达一种限定的意义

代词:.二者 通常用于句型中指代前文已经交代过的人和事(两人或者两件事情)

副词:二者,二者都

连词:不仅…而且…,…和 用于句子中两个人或者两件事是并列关系

列举如下例句请自己体会区别在哪里。

注意以下各句含义相同:Both boys have been ill, Both the boys have been ill, Both of the boys have been ill, The boys have both been ill(两个男孩都病了)。不能用 Both of boys have been ill,但在和代词一起使用时可以说 Both of them have been ill(他们两个都病了)。
