初一英语词汇复习:数词小结（三）
<p> 9.与数词相关的主谓一致原则</p><p> 1)当名词词组中心词为表示时间、路程、金钱或重量等复数名词时，往往根据意义一致的原则，把这些复数名词看做一个整体，谓语采用单数形式。如：</p><p> <span word="Twenty">Twenty</span> <span word="dollars">dollars</span> <span word="is">is</span> <span word="not">not</span> <span word="enough">enough</span>.</p><p> <span word="Two">Two</span> <span word="months">months</span> <span word="has">has</span> <span word="passed">passed</span> <span word="before">before</span> <span word="we">we</span> <span word="realized">realized</span>.</p><p> 但是如果数词单用，表示人或物，谓语动词一般用复数。如：</p><p> <span word="Three">Three</span> <span word="were">were</span> <span word="killed">killed</span> <span word="and">and</span> <span word="ten">ten</span> <span word="were">were</span> <span word="missing">missing</span> <span word="in">in</span> <span word="that">that</span> <span word="accident">accident</span>.</p><p> 2)如果名词词组中心词是分数或百分数+<span word="of">of</span>-词组，谓语动词的单、复数形式取决于<span word="of">of</span>-词组中名词或代词的单、复数形式：如果<span word="of">of</span>-词组中名词或代词是单数或不可数名词，谓语动词用单数形式；如果<span word="of">of</span>-词组中名词或代词是复数，谓语动词也用复数形式。如：</p><p> <span word="Two">Two</span> <span word="thirds">thirds</span> <span word="of">of</span> <span word="the">the</span> <span word="earth">earth</span> <span word="is">is</span> <span word="covered">covered</span> <span word="with">with</span> <span word="water">water</span>.</p><p> <span word="Two">Two</span> <span word="thirds">thirds</span> <span word="of">of</span> <span word="the">the</span> <span word="people">people</span> <span word="present">present</span> <span word="are">are</span> <span word="against">against</span> <span word="the">the</span> <span word="plan">plan</span>.</p><p> 3)如果主语是<span word="many">many</span> <span word="a">a</span>，<span word="more">more</span> <span word="than">than</span> <span word="one">one</span>+单数名词构成，尽管从意义上看是复数，但谓语动词仍用单数形式。如：</p><p> <span word="Many">Many</span> <span word="a">a</span> <span word="student">student</span> <span word="in">in</span> <span word="this">this</span> <span word="class">class</span> <span word="has">has</span> <span word="hoped">hoped</span> <span word="a">a</span> <span word="long">long</span> <span word="break">break</span>.</p><p> 4)<span word="a">a</span>+单数名词+<span word="or">or</span> <span word="two">two</span>做主语，谓语动词用单数形式。如<span word="one">one</span> <span word="or">or</span> <span word="two">two</span>+复数名词，谓语动词用复数形式。如：</p>
