高中英語必備知識點
虛擬條件句
條件狀語從句是非真實情況,在這種情況下要用虛擬語氣。
1.條件從句與現(xiàn)在事實不一致,句型為:If+主語十過去時,tiag+should (could,would,或might)+動詞原形,例如:If l were you,1 would study hard.
2.條件從句與過去事實不一致,句型為:If+主語+had+過去分詞,主語+should(could, would,或might)+have+過去分詞,例如:If I had not studied hard.1would have failed in the exam last term
3.條件從句與將來事實不一致,句型為:lf+主語+should/were to+do,主語+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條件句中絕對不可出現(xiàn)“would”。
2.根據(jù)句中的時間狀語,有時可能出現(xiàn)“混合虛擬”的情況,即主句可能是現(xiàn)在的情況,條件句也許是發(fā)生在過去的情況,但都遵守上述句型。
3.在條件句中如果出現(xiàn)were,had,should可省去if,將這些詞提前置于句首構(gòu)成倒裝,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,我就可以親眼目睹它的樣子了。

各種時態(tài)的被動語態(tài)
被動語態(tài)概述
被動語態(tài)的概念:它是動詞的一種形式,表示主語與謂語之間的執(zhí)行或被執(zhí)行關(guān)系。主動語態(tài)表示主語是謂語動作的執(zhí)行者,例如:They saw the little boy crying by the river.被動語態(tài)表示主語是謂語動作的承受者,例如:The little boy was seen crying by the river.
被動語態(tài)的構(gòu)成
被動語態(tài)的形式是由“助動詞be+動詞的過去分詞”構(gòu)成。助動詞be隨著主語的人稱、數(shù)、時態(tài)等的不同而變化。幾種常見時態(tài)的被動語態(tài)形式如下:
1.一般現(xiàn)在時am/is/are +過去分詞
例如:Rice is planted in the south of China.
2.一般過去時was/were +過去分詞
例如:These trees were planted the year before last.
3.一般將來時will/shall + be +過去分詞
例如:A sports meeting will be held next week in our school.
4.現(xiàn)在進(jìn)行時am/is/are + being +過去分詞
例如:Your radio is being repaired now.
5.過去進(jìn)行時was/were + being +過去分詞
When he got there, the problem was being discussed.
6.現(xiàn)在完成時have/has + been +過去分詞
His work has been finished.
Has his work been finished? Yes, it has. / No, it hasn’t.
