你的提問不準(zhǔn)確,樓上兄弟的回答也錯(cuò)誤哈!應(yīng)當(dāng)說,They做主語,each做同位語時(shí),謂語動(dòng)詞用復(fù)數(shù),如：
They each put forward a proposal.（請(qǐng)注意each做同位語時(shí)的位置,一般置于be之后或?qū)嵙x動(dòng)詞之前）,又如：
We each have our private views about it.
如果each做主語,謂語動(dòng)詞一般應(yīng)當(dāng)用作單數(shù),如：
Each of them thinks differet thoughts.
另,請(qǐng)?zhí)貏e注意以下兩種結(jié)構(gòu)：
1、each(every)+ 單數(shù)名詞 + and + 單數(shù)名詞,此時(shí)謂語動(dòng)詞用作單數(shù),如：
Each boy and girl has come and will sign his full name before attending the ceremony.
2、each(every)+ 單數(shù)名詞 + and + each(every) + 單數(shù)名詞,此時(shí)謂語動(dòng)詞用作單數(shù),如：
Each hour and each minute has its value.
最后,請(qǐng)注意,each of后的名詞前須加the,如each of the soldiers（不說each of soldiers!）
