【文章內(nèi)容簡介】 代替過去完成時，如The train had left before I got to the ：The train left before I got to the station.　　其他時態(tài)的比較，如一般現(xiàn)在時與現(xiàn)在進(jìn)行時，一般過去時與過去進(jìn)行時的用法比較不再列舉。時態(tài)的混合使用是以掌握好每一種時態(tài)的用法以及各時態(tài)的比較用法為基礎(chǔ)的，在中學(xué)階段使用較少，在此不做詳談。　　三、注意時態(tài)與時間不一致的特殊情況　　如前所述，判斷時態(tài)要從“標(biāo)志”（時間狀語）著眼，這是一般規(guī)律。但有些情況下，時態(tài)與時間（標(biāo)志）并不一致，在教學(xué)中應(yīng)引起足夠的重視，做到靈活使用，可視之為“特殊標(biāo)志”?！　。▌酉騽釉~）常用進(jìn)行時表示將來時，常見的這類動詞有arrive, e, go, leave, set off, start等、例如：The Browns are leaving for Paris next month.　　，也可用來表示說話時正在進(jìn)行的動作。例如：Are you free tomorrow? The train starts at 7:50 in the evening. Here es the bus! There goes the bell!　　（即虛擬語氣）。例如：I wish I could fly to the moon by spaceship. It’s high time you went home. If I were you, I would go with him.　　，當(dāng)主句是將來時態(tài)或是祈使句時，狀語從句應(yīng)用一般現(xiàn)在時或現(xiàn)在完成時代替一般將來時，用一般過去時代替過去將來時。例如：I will go to town if it doesn’t rain tomorrow. He said he would e to see us if he had time. Please tell him about it as soon as he es back. Are you going to play with us when you have finished your homework?　　，主從句動詞時態(tài)有如下不一致情況。　　(1)當(dāng)賓語從句表示科學(xué)真理、客觀事實(shí)、格言或其他不受時間影響、限制的客觀存在的事物時，如：Long ago people didn’t know that the earth moves round the sun. She told hers on that practice makes perfect.　　(2)當(dāng)賓語從句用來解釋、表達(dá)科技內(nèi)容時，如：The teacher told us that the attraction of the earth for all bodies is called gravity.　　(3)當(dāng)賓語從句表示一種反復(fù)出現(xiàn)或目前習(xí)慣性動作時，如：He said he does morning exercises everyday.　　(4)當(dāng)賓語從句中謂語動詞的動作在轉(zhuǎn)述時仍在繼續(xù)，或表示現(xiàn)在時刻仍存在的狀態(tài)時，如：LiLei said his father is attending a meeting in Shanghai. She told me the other day that she is only seventeen.　　，如比較狀語從句、定語從句等不受主句時態(tài)的影響，應(yīng)根據(jù)實(shí)際需要，選擇適當(dāng)?shù)臅r態(tài)。例如：It was colder yesterday than it is today. Last night I read the book which you are reading now.　　對于這些特殊情況，在平時的教學(xué)中，應(yīng)特別注意。其實(shí)，我們也可以把上述情況視為一種特殊的“標(biāo)志”，進(jìn)而判斷相應(yīng)的時態(tài)形式。初中英語動詞時態(tài)專項(xiàng)訓(xùn)練一、用所給詞的適當(dāng)形式填空： 1．He__________swimming in the river every day in summer.
