語法小知識：代詞及其先行項的“數”的一致
同學們在使用代詞時，常會有疑問：代詞的數應該根據什麼進行選擇呢？這個問題常困擾大家，不應擔心，小編爲大家整理了全面的解析，一起來看看吧~
當先行項爲everyone, everybody, on one, anyone, anybody, someone, somebody等複合詞時，代詞以及相應的限定詞通常按照語法一致原則用單數形式。
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.
但在非正式語體中也可以根據意義一致的原則，用複數代詞。
例如：
Someone left their umbrella behind yesterday.
No one could have blamed themselves for that.
先行項爲某些並列結構時，一般根據該並列結構的單、複數意義來決定代詞以及相應限定詞的單、複數形式。
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.
當先行項爲某些集體名詞時,隨後的代詞以及相應的限定詞應依據該集體名詞用於何種意義而定。
例如：
The team has won its first game.
The team are now on the floor taking their shots at the basket.
當先行項爲“複數名詞或代詞 + each”時，代詞的選擇。當先行項爲複數名詞或代詞作句子主語並帶有each作同位語時，如果each 出現在動詞之前，隨後的人稱代詞或相應的限定詞用複數；如果each 位於動詞之後，隨後的人稱代詞或相應的限定詞用單數。
例如：
They each had their problems.
They had each his own problem.
看完了小編爲大家呈上的解析，是不是清晰多了呢？以後就不用擔心用錯代詞的數啦，趕快收藏哦~
