高考英语重点复习知识点

1、被动语态 HYPERLINK /view/135.htm t _blank 被动语态是 HYPERLINK /view/26589.htm t _blank 动词的一种形式，用以说明 HYPERLINK /view/1209.htm t _blank 主语与 HYPERLINK /view/330413.htm t _blank 谓语动词之间的关系。 HYPERLINK /view/1458.htm t _blank 英语的语态共有两种： HYPERLINK /view/1403041.htm t _blank 主动语态和 HYPERLINK /view/135.htm t _blank 被动

2、语态。主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。被动语态是动词的一种特殊形式，一般来说，只有需要动作对象的及物动词才有被动语态。 HYPERLINK /view/1711.htm t _blank 汉语往往用被、受、给等被动词来表示被动意义 。1定义 HYPERLINK /link?url=sq9s9kf2XOBp4jggEFBwLe5NFMdA-dKbHQCPPgZc5istXMqx5aBDmCkJhd2KnxqYJE9YYTcbjoSokRBDa5BYPK o 编辑本段 编辑在 HYPERLINK /view/1458.htm t _blank 英语中，被动语态使用得

3、比 HYPERLINK /view/1711.htm t _blank 汉语要多，要普遍，但大多数句子都使用主动语态。被动语态在英语中极为重要。许多课本及考试乃至实际应用中都常常涉及到这个问题。一般说来，当强调动作承受者，不必说出执行者或含糊不清的执行者时，多用被动语态。需要注意的是，许多地方与 HYPERLINK /view/1711.htm t _blank 汉语不同。注意：那些 HYPERLINK /view/1711.htm t _blank 汉语中有“被”的短语往往又不是被动语态，而是 HYPERLINK /view/2236207.htm t _blank 主系表结构。还有些特殊现

4、象，如：“known to me的意思，英语却应该用被动态。还要注意，英语的被动语态往往由“by”引出，而有用 HYPERLINK /view/84281.htm t _blank 介词“by on foot”步行（美国人有时用“by foot”），“in carriage”（乘四轮马车）等等。还有假主动，真被动的十几个常用词的用法，以及“so heavy to carry”而不用“so heavy to be carried”等习惯用法。有关这类情况，做到心中有数对全面掌握 HYPERLINK /view/135.htm t _blank 被动语态，准确无误地解答习题非常关键，被动态必须涉及

51、用于 HYPERLINK /view/314131.htm t _blank 肯定句。但如果“can”或“may”的 HYPERLINK /view/901109.htm t _blank 过去式即“could”与“might”与 HYPERLINK /view/345.htm t _blank 不定式完成体或完成进行体搭配时，可用于各种结构。肯、否、陈、疑，均可。It cant have been lost in the post, can it?它不可能是在邮局丢失的吧：（反意疑问句）否定助后加“not”，疑问一助置主前。在 HYPERLINK /view/312417.htm t _bl

52、ank 否定句的被动态中，否定副词“not”一定加在第一 HYPERLINK /view/78719.htm t _blank 助动词之后，不放在别的助动词之后。同样在疑问句的被动态中，第一 HYPERLINK /view/78719.htm t _blank 助动词置于主语之前。例：Why has（一助）not anything been（二助）done to end the strike?“not”必须放在第一 HYPERLINK /view/78719.htm t _blank 助动词“has”之后，第一助动词“has”必须放在主语“ HYPERLINK /view/4810002.ht
