解题指导：neither和either的用法
1．共同点：
1）它们都可用作主语、宾语和定语.
例如：①Neither of the books is good.（主）
②He phoned neither of us yesterday.（宾）
③Neither way is correct.（定）
④I don't think either of them is at home.（主）
⑤Here are two knives.You can take either of them.（宾）
⑥There are shops on either side of the street.（定）
2）Neither和either作定语时,其后的名词都用单数.例如：
Neither book gives the answer.
There are tall buildings on either side of the road.
2．不同点：
neither是表示“两都不”的否定说法,而either是表示“两人或两物中任何一个”的肯定说法.
注意：
A.either作为副词表示“也”,不同于too,also,either通常用于否定句的末尾,too通常用于肯定句的句 末；而also通常用于肯定句和疑问句中,其位置一般用在to be之后,其它动词之前.如：
①Tom has been to Beijing.Mary has been to Beijing____（96江西）
A.neither B.either C.too D.also
此题应选C.
②She is also a teacher.
③She also likes singing.
④I can't speak French.My sister can't speak French,either.
B.neither作为副词表示“也不”,常常用于倒装句的开头,紧跟在一个否定句后面（当然nor也可以这么 用）.那么,如果是肯定句呢?我们要用so,依然是倒装语句.例如：
I can't sing an English song.Neither can he.
I can sing an English song.So can he.
还应注意neither和so后面的助动词和情态动词其后的主语在人称、时态方面保持一致.
C.neither和either在句中作主语时,谓语动词必须用单数形式.如：
Neither of them knows Japanese.
Either of them knows English.
D.neither本身表示否定,其后不能再用否定式.如：
两个答案都不对.
【误】Neither answer isn't right.
【正】Neither answer is right.
E.either与not连用表示“两者都不”,此时相当于neither.如：
I don't want either of them=I want neither of them.我两个都不想要.
