    高中英语必备知识点
    虚拟条件句
    条件状语从句是非真实情况,在这种情况下要用虚拟语气。
    1.条件从句与现在事实不一致,句型为:If+主语十过去时,tiag+should (could,would,或might)+动词原形,例如:If l were you,1 would study hard.
    2.条件从句与过去事实不一致,句型为:If+主语+had+过去分词,主语+should(could, would,或might)+have+过去分词,例如:If I had not studied hard.1would have failed in the exam last term
    3.条件从句与将来事实不一致,句型为:lf+主语+should/were to+do,主语+should( could.)+原形do,例如:If l were to go to the moon one day,I could see itwith my own eyes.
    注意:
    1.If条件句中绝对不可出现“would”。
    2.根据句中的时间状语,有时可能出现“混合虚拟”的情况,即主句可能是现在的情况,条件句也许是发生在过去的情况,但都遵守上述句型。
    3.在条件句中如果出现were,had,should可省去if,将这些词提前置于句首构成倒装,例如:w.re I to go tothe moon one clay,1 would see it with my own eyes.如果有一天我登上月球,我就可以亲眼目睹它的样子了。

    各种时态的被动语态
    被动语态概述
    被动语态的概念:它是动词的一种形式,表示主语与谓语之间的执行或被执行关系。主动语态表示主语是谓语动作的执行者,例如:They saw the little boy crying by the river.被动语态表示主语是谓语动作的承受者,例如:The little boy was seen crying by the river.
    被动语态的构成
    被动语态的形式是由“助动词be+动词的过去分词”构成。助动词be随着主语的人称、数、时态等的不同而变化。几种常见时态的被动语态形式如下:
    1.一般现在时am/is/are +过去分词
    例如:Rice is planted in the south of China.
    2.一般过去时was/were +过去分词
    例如:These trees were planted the year before last.
    3.一般将来时will/shall + be +过去分词
    例如:A sports meeting will be held next week in our school.
    4.现在进行时am/is/are + being +过去分词
    例如:Your radio is being repaired now.
    5.过去进行时was/were + being +过去分词
    When he got there, the problem was being discussed.
