（1）主語形式雖為單數，但意義為複數，謂語動詞要用複數形式。如：My family are having supper now.
（2）主語形式為複數而意義上卻是單數，謂語動詞要用單數形式。名詞詞組中心詞為表示度量、距離、金額、時間等複數名詞，可以根據意義一致原則，把複數名詞看作整體，謂語動詞用單數形式。如：Thirty dollars is too expensive for this diary.Three years has pasd.
（3）“half of，plenty of ，a（large）quantity of ，the rest of，the remainder of，a heap of，heaps of + 可數或不可數名詞”構成短語作主語，謂語形式是用單數還是複數取決於表示的意義。如：Half of the Ameribsp;people have never read a neer.Half never voted for President.One hopes it is the same half.（Gore Vidal）The first half of our lives is ruined by our parents，and the d half by our children.（Clarenbsp;Darrow）That’s the cret of eaining.You make your guests feel wele and at home.If you do that holy，the rest takes care of itlf.（Barbara Hall）
