文档列表 文档介绍
一语法及基础知识 第一节 虚拟语气 过去 现在 未来
现在为从句did原 主句would should could might +do
过去从句为为had+did主句would could should might +have done
未来为从句为were to do did were should+do did主句为四大词+do
三个时态虚拟分别于三个时间事实相反
Were should had 三个词能够提前 放在一句话第一位
判定未来时时注意关键时间词 现在时为 now未来时为tomorrow
If I had time if qing had gone
现在例句 if my lived now,he would give us more shows
过去例句if qing had not gone back to qing dynasty ,she would not have met him
下一个if I had been born 20 years earlier,I would have had chance to marry her
未来例句两个而且三字词提前了 I were to win 变成were I to win I should win变成
Should I win qingchuan had not gone the eighth son of the emperor
Have 为实义动词时+n 而且have 不放在前面什么意思 have为助动词时能够放在前面
第二节介词短语仅替换从句 without 假如没有 but for 要不是
Without me,what would you do ?原来应该为you would do 但有what 为疑问语气所以
But for the earthquake we should not have bought the salt crazily
If it had not been for 其实就是without but for 和if作用一样
第三届 错综时间条件句 前后时间不一致
If you had taken my advise you would be better now 有显著时间状语
二表示愿望虚拟 为不可能实现事
Hope能够实现愿望 wish 不能够实现愿望
Wish+that +主语+和现在过去未来事实相反
例子I wish (that)从句everyday were my birthday 现在
I wished(that)I had met jaychou
Would /could+do和未来相反
I wish(that)they would become my enemies in the future
三 should+do虚拟
Should能够省略 在部分动词以后 一个坚持二个命令 四个提议 四个要求 一个宁愿 宁愿坚持提议命令要求 部分动词以后+(that)+主+(should)+do
Prefer
Insist
Suggest advise propose recommend
Order command
Require request demand desire
注意insist后面要求应是should do 假如后面是认为 断言 意思 后不虚拟
The doctor insisted that the boy was (be)badly hurt and insisted that he should be sent (send)to the hospital at once
被动语态 be+done suggest 提议(should)do 暗示表明不虚拟
Her pale 苍白face suggested that she was(be)will
同源词使用方法相同 suggested tion ing undesirable 后面全部是should +do 一个词衍生好多个词,要掌握那一个词就行
2一个句型以后it is important/ essential/ necessary /strange/ natural /apity/ (should)do
It is important that he (should)not come
(should)不能省略 it is (high|about)time that 主 +should do 该到做某事时候了
It is high time that we should study hard 能
