【文章內(nèi)容簡介】 e were to have e yesterday, but we couldn’t. 2)intended (expected, hope, meant, planned, supposed, wished, wanted, desired) + to have done sth,例如： I meant to have told you about it, but I forgot to do so. (3)過去完成時(shí)常用于以下固定句型： 1)hardly, scarcely, barely + 過去完成時(shí)+ when + 過去時(shí)。例如： Hardly had I got on the bus when it started to move. 2)no sooner +過去完成時(shí)+ than +過去時(shí)。例如： No sooner had I gone out than he came to see me. 3)by (the end of ) +過去時(shí)間，主句中謂語動(dòng)詞用過去完成時(shí)。例如： The experiment had been finished by 4 o’clock yesterday afternoon. 將來完成時(shí)表示在將來某一時(shí)刻將完成或在另一個(gè)未來的動(dòng)作發(fā)生之前已經(jīng)完成的動(dòng)作；也可以用來表示一種猜測。常與將來完成時(shí)連用的時(shí)間狀語有：by (the time / the end of ) +表示將來時(shí)間的短語和句子；before (the end of ) +表示將來時(shí)間的詞語或句子；when, after等加上表示將來動(dòng)作的句子等。例如： 1)By this time tomorrow you will have arrived in Shanghai. 2)I shall have finished this position before 9 o’clock. 3)When we get on the railway station, the train will probably have left. 完成進(jìn)行時(shí)是完成時(shí)的強(qiáng)調(diào)形式，有現(xiàn)在完成進(jìn)行時(shí)，過去完成進(jìn)行時(shí)，將來完成進(jìn)行時(shí)。 (1)現(xiàn)在完成進(jìn)行時(shí)表示過去某一時(shí)刻之前開始的動(dòng)作或狀態(tài)一直延續(xù)到過去某一時(shí)刻。例如： I have been looking for my lost book for three days, but I still haven’t found it. (2)過去完成進(jìn)行時(shí)表示過去某一時(shí)刻之前開始的動(dòng)作或狀態(tài)一直延續(xù)到過去某一時(shí)刻。例如： It had been raining cats and dogs for over a week and the downpour had caused landslides in many places. (3)將來完成進(jìn)行時(shí)表示在將來某一時(shí)刻之前開始的一個(gè)動(dòng)作或狀態(tài)一直延續(xù)到將來某一時(shí)刻。例如： By the time you arrive tonight, she will have been typing for hours. 四：時(shí)態(tài)一致 時(shí)態(tài)一致是英語四、六級考試的一個(gè)重要內(nèi)容。通常應(yīng)由主句謂語的時(shí)態(tài)決定從句的謂語時(shí)態(tài)。一般原則是： 當(dāng)主句謂語使用現(xiàn)在時(shí)或?qū)頃r(shí)，從句的謂語根據(jù)具體情況使用任何時(shí)態(tài) He says that he lives in Wuhan. We hope that there will be many people at your party today. “Did you hear that Bill finally sold the house?” “Yes, but I don’t know who bought it.” “There’s a lot of excitement on the street.” “There certainly is. Do you suppose the astronauts have returned?” 當(dāng)主句謂語使用過去時(shí)的時(shí)候，從句的謂語必須使用過去范圍的時(shí)態(tài) He said he was writing a novel. The teacher wanted to know when we would finish the experiment. He said his father had been an engineer. 當(dāng)從句是表示沒有時(shí)間概念的真理時(shí)，從句的謂語應(yīng)使用一般現(xiàn)在時(shí)。例如： The teacher told them since light travels faster than sound, lightning appears to go before thunder. 注：在此種情況下，即使主句謂語用了過去式的各種時(shí)態(tài)，從句謂語也應(yīng)用一般現(xiàn)在時(shí)。 從句謂語只能用虛擬語氣的情況 利用時(shí)態(tài)一致原則確定從句動(dòng)詞時(shí)態(tài)時(shí)，還應(yīng)注意，若主語動(dòng)詞是表示命令、請求、要求、建議、勸告等的動(dòng)詞，從句謂語只能用虛擬語氣，不能遵循時(shí)態(tài)一致原則。例如： We insisted that we do it ou
