  b. all 都,指三者以上。

  all 的主谓一致:all的单复数由它所修饰或指代的名词的单复数决定。

  all 通常不与可数名词单数连用,如:不说 all the book,而说 the whole book。

  但all可与表时间的可数名词单数连用,如 all day,all night,all the year; 但习惯上不说 all hour,all century。

  all还可以与一些特殊的单数名词连用,如 all China, all the city, all my life, all the way

  b. both, all 都可作同位语,其位置在行为动词前, be 动词之后。如果助动词或情态动词后面的实义动词省 去,则位于助动词或情态动词之前。

  Who can speak Japanese?  We both (all) can.

  4) neither 两者都不

  a. neither作主语时,谓语动词用单数。

  b. 作定语与单数名词连用,但neither… nor 用作并列连词,可与复数名词连用。其谓语采用就近原则。

  c. 可用于下列句型,避免重复。
