代詞后面該單數(shù)還是復(fù)數(shù)?

　　代詞和物主限定詞單、復(fù)數(shù)形式的選擇通常取決于它們的指示對(duì)象，即先行項(xiàng)的單、復(fù)數(shù)形式。舉例來(lái)說(shuō)，All members of the group have already made their decisions. 這里，all members是指示對(duì)象(先行項(xiàng))，所以其后的代詞選用their。關(guān)于代詞單、復(fù)數(shù)形式的選擇，我們還需要注意以下幾點(diǎn)：

　　1. 先行項(xiàng)為every-，some-等復(fù)合詞時(shí)：語(yǔ)法一致原則，代詞一般用單數(shù)：

　　Anybody can come here if he is interested.

　　注：當(dāng)先行項(xiàng)為everybody，everyone時(shí)，代詞一般用復(fù)數(shù)更為自然。

　　Everyone was clapping their hands.

　　當(dāng)先行項(xiàng)為everything，anything，something，nothing時(shí)，代詞用單數(shù)。

　　Everything in the bag is broken, isn’t it?

　　2. 先行項(xiàng)為并列結(jié)構(gòu)時(shí)：意義一致原則。

　　My friend and roommate has done well in her exam, so she is happy now.

　　My friend and roommate have agreed to lend their bikes to me.

　　3. 先行項(xiàng)為集體名詞時(shí)：意義一致原則。

　　The team has won its first game.

　　The team are now preparing themselves for the next game.

　　3. 先行項(xiàng)為“...+each”時(shí)：

　　若each在動(dòng)詞后，代詞則為單數(shù)：They had each his own problem.

　　若each在動(dòng)詞前，代詞則為復(fù)數(shù)：They each had their problems.
