你所給的結(jié)構(gòu)不對(duì).
如果要想了解Each的用法.必須對(duì)比才能看出：
each both either neither
both:兩個(gè)都(用于肯定)
each:每個(gè)(表個(gè)體)
Every:每個(gè)(表全體)
neither:兩個(gè)都不(用于否定)
either:1).或者(用于選擇)常與or 連用
2).也(表相同)(用于否定)
e.g.:
1.Both the students are girls.
2.Each student has a pen.
3.Neither the student is from London.
4.Either he or she has a pen.注：has是被she 限定的,意思就是說,動(dòng)詞的形式與or 后面的主語一致.
例如,Either he or I have a pen.
He doesn't have a pen,she doesn't have,either.

（2）each指兩個(gè)或兩個(gè)以上的人或事物中的“每個(gè)”.：

（3）each作為形容詞,修飾單數(shù)名詞,接單數(shù)動(dòng)詞.作為代詞,單獨(dú)使用,接單數(shù)動(dòng)詞；放在復(fù)數(shù)名詞和代詞后作同位語,接復(fù)數(shù)動(dòng)詞.each of them后可接單數(shù)或復(fù)數(shù)動(dòng)詞.如：
