1、1 吉林省长春市实验中学高考英语一轮复习虚拟语气一、语气的定义和种类。1 语气 (mood) 语气是动词的一种形式，表示说话人对某一行为或事情的看法和态度。2 语气的种类a. 陈述语气：表示动作或状态是现实的、确定的或符合事实的，用于陈述句、疑问句和某些感叹句。如： There are two sides to every question. Were you busy all day yesterday? How good a teacher she is! b. 祈使语气：表示说话人对对方的请求或命令。如： Never be late again! Don t forget to turn
2、 off the light.c. 虚拟语气：表示动作或状态不是客观存在的事实，而是说话人的主观愿望、假设或推测等。如：If I were a bird, I could fly in the air. I wish I could pass the examination. 二虚拟语气在条件从句中的用法。条件从句有两类，一是真实条件句，另一是虚拟条件句。如果假设的情况可能发生，是真实条件句，这种情况下谓语用陈述语气，否则就是虚拟条件句，要使用虚拟语气。如：If time permits, we ll go fishing together.If you had come yesterday,
3、 you would have met that famous professor.（隐含的事实是：你昨天没来，也没见到那位著名教授）。在含有虚拟条件句的复合句中，主从句的谓语都要用虚拟语气，现将其形式列表如下：动词形式时间从句主句与现在事实相反动词过去式(be的过去式用 were) would(could/should/might)+动词原形与过去事实相反had+动词过去分词would(could/should/might)+hav e 过去分词与将来事实可能相反动词过去式should+ 动词原形were to+ 动词原形would(could/should/might)+动词原形1表示与现
4、在事实相反的假设和结果。如： If I were you, I should(would ,could, might) tell him the truth. If she had time, she would(could, might, should) help me. 2 表示与过去事实相反的假设和结果。如： If I had known your telephone number yesterday, I should (would, could, might) have telephoned you. If you had taken my advice, you wouldnt(c
5、ouldn t) have failed in the exam.3 表示与将来事实可能相反的假设和结果。如： If it should rain, the crops would (could, might) be saved. -What would happen if I put the paper on the fire? -It would burn. 三虚拟语气的其它用法。1 虚拟语气在主语从句中的用法。 在“It is important (strange, natural, necessary) that”这类句型中，that所引 导的主语从句 中的谓语动词常用“(should
6、)+ 动词原形”结构，表示某事是“重要”， “奇怪”， “自然”， “必要”精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 1 页，共 7 页2 等意义。如：It is important that every Beijinger (should) be able to speak English.

7、(should) + 动词原形”结构，表示建议，命令，要求和愿望。如： It is requested that Class Two (should) give a performance at the English evening. 2 虚拟语气在宾语从句中的用法。（1）在动词wish 后的宾语从句中，表示与现在或过去的事实相反，或对将来的主观愿望，从句通常省略连词 that 。a. 表示对现在情况的虚拟：从句动词用过去式或过去进行式(be 的过去式用were ) 表示，I wish I knew the answer to the question.

8、ing in my hometown all the year around. b. 表示对过去情况的虚拟：从句动词用 had+ 过去分词。如：I wish (that) I hadnt wasted so much time. He wishes (wished) he hadnt lost the chance. c. 表示对将来的主观愿望：谓语动词形式为“would/should/could/might+动词原形”，此时要注意，主句的主语与从句的主语不能相同，因为主句的主语所期望的从句动作能否实现，取决于从句主语的态度或意愿（非动作名词除外）。如：I wish it would stop
9、 raining. I wish you would be quiet. （2）在 suggest （建议） , demand( 要求 ), order(命令 ), propose(建议 ), insist（坚持要做） , command( 命令 ), request(要求 ), desire(希望 ) 等动词后的宾语从句中，谓语动词用“(should)+动词原形”，表示建议，要求，命令等。如：I suggest that we (should) start the meeting at once. The undergraduate insisted that he (should) go
10、to work in the south. 注：当 suggest 表示暗示，主语为something ；insist表示坚持观点时，后接的宾语从句当用真实语气。比较：His silence suggested that he agreed with my decision. He suggested that I (should) stick to my decision.

12、ly. 4. 虚拟语气在同位语从句中的用法当先行词为advice, suggestion, order, proposal等表示建议，命令，要求和愿望的名词时，从句中的谓语动词常用“ （should ）+ 动词原形”结构。如： The suggestion came from the manager that the new rule (should) be adopted. 5特殊的虚拟语气结构。（1）虚拟语气用在状语从句中由 as if 或 as though引导的状语从句表示比较或方式时，从句中的谓语动词用虚拟语气。动词形式用动词的过去式(be were) 或 had+过去分词。如： T
