1、 課題名稱 二輪復(fù)習(xí)—— 情態(tài)動(dòng)詞和虛擬語氣 學(xué)習(xí)目標(biāo)：1 自主學(xué)習(xí)創(chuàng)新教程情態(tài)動(dòng)詞和虛擬語氣內(nèi)容。 2分析歷年熱門考點(diǎn)進(jìn)行實(shí)戰(zhàn)演練。 學(xué)習(xí)難點(diǎn)：3各類從句中的虛擬語氣 一、復(fù)習(xí)時(shí)需注意的要點(diǎn) （一）情態(tài)動(dòng)詞 1、情態(tài)動(dòng)詞在句中沒有人稱和數(shù)的變化。 2、含有情態(tài)動(dòng)詞的句子改為否定句或疑問句不必加助動(dòng)詞，只需要將情態(tài)動(dòng)詞置于主語前，或在情態(tài)動(dòng)詞后加上not。 例如：Must I write a letter to cheer him up? You needn’t wait for me. 3、 情態(tài)動(dòng)詞的過去式，例如can—cou

2、ld，may—might。但是少數(shù)情態(tài)動(dòng)詞只有過去式，例如used to表示過去常常。must的過去式往往用had to代替。 4、 情態(tài)動(dòng)詞后還可接不定式的進(jìn)行式、完成式和被動(dòng)式。 例如：He can’t be doing his homework now. 他現(xiàn)在不可能在做功課。 He must have attended the meeting last night. 昨晚他一定參加了會(huì)議。 （二）虛擬語氣 1、 在if條件句中，如果含有were , should或had等助動(dòng)詞，if可以省去，句子用倒裝。 例如：Were I you , I would buy this r

3、eference book. 2、 should與would都可以用于if條件句的主句中，但should一般只用于第一人稱，would用于所有人稱。 例如：If you were here , I would tell you the news . 3、 某些條件可以用介詞短語without… , but for 等來表示 。 例如：Without your help , I could not have succeeded in passing the exam . 4、 有時(shí)句子通過but或otherwise等詞來表示真實(shí)與虛擬的轉(zhuǎn)換，在這種情況下，只有不真實(shí)的部分用虛擬式。

4、例如：I was ill yesterday；otherwise I would have played football with you . But for the heavy rain , we would have gone to the concert . 5、 有suggest等詞的相應(yīng)的名詞組成的同位語從句及表語從句用虛擬式。 例如：I accepted my mother’s suggestion that I should eat an apple every day . 二、2020;2020考題分析 1.(08全國Ⅱ17) Liza well not wan
