高考英语 数词 介词考点透析与精炼

高考英语数词介词考点透析与精炼 考试要求： 介词是高考英语试题中比较重要的一个考查点，近年来的高考在单项填空题中直接涉及到对介词的考查，主要包括常用近义介词的用法区别、介词的常见搭配、介词在特定语境中的选用和介词短语的用法等。 高考试题对数词的考查比重较小，主要以对倍数的表达方法及概数的考查为主。 知识总结： 数词部分 dozen和score的复数形式应注意以下几点： dozen表示一打，十二个；score表示二十；当dozen与数词，或many，several等连用时，不加“s”，所修饰的名词前常省去of，score则不然。 two dozen pencils两打铅笔 two score of pencils四十支铅笔 dozens of people= scores of people许多人 当后面的名词前有限定词时, dozen后应加of。 a dozen of these people two dozen of them three score and ten people（中不加of）七十人 序数词的用法： 序数词一般由基数词后加th构成，前面一般加定冠词the，表示“第几”；加不定冠词，则意为“又一，再一”。 I can do better if I have a second chance. 如果再有一次机会，我能做得更好。 基数词与序数词连用时，通常是序数词在前： the first two pages of the book 这本书的前两页 分数的表示法 分数由基数词和序数词合成，分子用基数词，分母用序数词，分子大于1时，分母的序数词要用复数形式。 1/3：one(a)third 2/3：two thirds three-sevenths：七分之三 特殊的表达： 1/2：one(a)half 1/4：one (a) quarter/one (a) fourth 3/4：three quarters 分子与分母之间加in或out of,分子在前，分母在后，分子分母都用基数词。 one in/ out of ten：十分之一 five in/ out of eight：八分之五 百分数的表示法： 表示百分数直接将数词放在单词percent前面即可：twenty percent=20% 百分之二十注意：分数和百分数后面不能直接接名词或代词，而用以下形式： 分数/ 百分数+of +冠词/ 限定词+名词/ 代词，其谓语动词与of后的名词在人称和数上保持一致。 Two-thirds of the money was spent on food.
