高中英語(yǔ)必備知識(shí)點(diǎn)
虛擬條件句
條件狀語(yǔ)從句是非真實(shí)情況，在這種情況下要用虛擬語(yǔ)氣。
1.條件從句與現(xiàn)在事實(shí)不一致，句型為：If+主語(yǔ)十過(guò)去時(shí)，tiag+should (could，would，或might)+動(dòng)詞原形，例如：If l were you，1 would study hard.
2.條件從句與過(guò)去事實(shí)不一致，句型為：If+主語(yǔ)+had+過(guò)去分詞，主語(yǔ)+should(could, would，或might)+have+過(guò)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(lái)事實(shí)不一致，句型為：lf+主語(yǔ)+should/were to+do，主語(yǔ)+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(duì)不可出現(xiàn)“would”。
2.根據(jù)句中的時(shí)間狀語(yǔ)，有時(shí)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(guò)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。

被動(dòng)語(yǔ)態(tài)的構(gòu)成
被動(dòng)語(yǔ)態(tài)的形式是由“助動(dòng)詞be+動(dòng)詞的過(guò)去分詞”構(gòu)成。助動(dòng)詞be隨著主語(yǔ)的人稱、數(shù)、時(shí)態(tài)等的不同而變化。幾種常見(jiàn)時(shí)態(tài)的被動(dòng)語(yǔ)態(tài)形式如下：
