虚拟语气[1]

4．用在It is time that ... 结构中，表示“该干某事了”， 含建议的意思，用动词过去式。It is time (that) we went to bed. 咱们该睡觉了。 注意: time 前可加about（表示“大约”）或high（表 示“强调”）等。 5．wish后宾语从句中的虚拟语气 从句用一般过去时或过去进行时表示一种与现在事 实相反的愿望：用过去完成时或过去完成进行时表 示与过去事实相反的愿望：若用would则表示请求 或对现状不满希望将来有所改变等。If only的用法 和I wish等基本相同，只是更富有感情色彩。

6．1est方式状语从句中的虚拟语气 从句用should+原形或直接用原形，不受主句动 词时态的任何影响。
• 【真题】You would not have failed if__________(按照我的指令去做).(2009.12) • 【解析】本题考点有两个：首先最重要的考点是if 从句的虚拟语气考查;根据语法规定，如果主句中出 现would +have的形式，从句中应该采用had+过去 分词的结构;第二是固定搭配“按照…的指令”表达 为follow my instructions 或者是follow my orders 注意多样化的表达，两者选其一就可以;注 意很多学生出现遗漏主语you，造成不必要的失分。 • 【答案】you had followed my instructions 或者 you had followed my orders
虚拟语气 历年真题中涉及到虚拟语气的 考点可以归纳如下： (1)(should)+动词原形的情形;
(2)if或but for等引导的条件句;
(3)wish, if only, would rather, It is(high)time that„的用法。

分词的用法
• 分词是非限定性动词的一种，即它不能单 独用作句子的谓语，而是充当句子的辅助 成分。 • 分词可以分为一般时现在分词、完成时现 在分词和过去分词，它的规则变化是由动 词加-ing或-ed 变化而来，因此分词的一个 显著特点是具有动作性。
分词做定语
• 1.根据时态、语态不同 • 1.1现在分词的一般式表示分词动作正在进行或保 持的一种状态。 • 1）a flying plane 一架正在飞行的飞机 • 2) a room facing the south 朝南的房间 • 1.2过去分词用来表示已经完成的动作或被动的意 思。 • 1）a story written by Mark Twain. • 2) a bridge built in 1930.
3.分词与动名词做定语的比较
• 分词做定语，它与被修饰名词肯定存在主 谓关系或动宾关系。 • A running train-----the train is running • The problem left----the problem is left • 动名词做定语，主要说明被修饰的名词的 用途、目的、特性等。 • Drinking water
• 3.表示原因、背景，相当于because从句 • Not having received a reply, he decided to write again.
• 完成式现在分词更强调分词动作发生在谓 语动作之前。
• 独立主格形式 • 当分词短语带有自己独立的逻辑主语，与 主句的主语无关时，称为独立主格，being 在独立主格中常常被省略。 • Weather permitting, we shall go to the city park. • He came into the room, his face (being) red with cold.
