同学们在使用代词时，常会有疑问：代词的数应该根据什么进行选择呢？这个问题常困扰大家，不应担心，沪江小编为大家整理了全面的解析，一起来看看吧~

当先行项为everyone, everybody, on one, anyone, anybody, someone, somebody等复合词时，代词以及相应的限定词通常按照语法一致原则用单数形式。

例如：

Anybody can attend the meeting if he is interested.

Everybody talked at the top of his voice.

If anyone calls, tell him I’ll be back later.

但在非正式语体中也可以根据意义一致的原则，用复数代词。

例如：

Someone left their umbrella behind yesterday.

No one could have blamed themselves for that.

先行项为某些并列结构时，一般根据该并列结构的单、复数意义来决定代词以及相应限定词的单、复数形式。

例如：

My friend and roommate has agreed to lend me his car.

My friend and my roommate have agreed to lend me their car.

当先行项为某些集体名词时,随后的代词以及相应的限定词应依据该集体名词用于何种意义而定。

例如：

The team has won its first game.

The team are now on the floor taking their shots at the basket.

当先行项为“复数名词或代词 + each”时，代词的选择。当先行项为复数名词或代词作句子主语并带有each作同位语时，如果each 出现在动词之前，随后的人称代词或相应的限定词用复数；如果each 位于动词之后，随后的人称代词或相应的限定词用单数。

例如：

They each had their problems.

They had each his own problem.

看完了小编为大家呈上的解析，是不是清晰多了呢？以后就不用担心用错代词的数啦，赶快收藏哦~
