過去進(jìn)行時(shí)主要表示過去某一時(shí)刻正在進(jìn)行的動(dòng)作，或表示過去某一階段一直在進(jìn)行的動(dòng)作。一起和小編來看一下過去進(jìn)行時(shí)的易錯(cuò)題吧！
?? 　一、丟掉be動(dòng)詞或忘記把動(dòng)詞變成現(xiàn)在分詞
　　例：1 I watching (watch) TV when he came in.
　　2 They were play (play) games at 5:00 p.m. yesterday.
　　答案：1 was watching 2 were playing
　　解析：現(xiàn)在進(jìn)行時(shí)中“be+現(xiàn)在分詞,缺一不可”的規(guī)律也可應(yīng)用于過去進(jìn)行時(shí)。

　　二、對(duì)動(dòng)詞或動(dòng)詞詞組提問時(shí)丟掉doing
　　例：We were flying kites at 5:00 p.m. yesterday. (對(duì)劃線部分提問)
　　What were you at 5:00 p.m. yesterday?
　　答案：What were you doing at 5:00 p.m. yesterday?
　　解析：現(xiàn)在進(jìn)行時(shí)中“What……doing……”?句式同樣適用于過去進(jìn)行時(shí)。

　?? 三、易把be+現(xiàn)在分詞記成be+過去分詞
　　例：He was talked (talk) to his mum at that time.
　　答案：was talking
　　解析：過去進(jìn)行時(shí)與現(xiàn)在進(jìn)行時(shí)結(jié)構(gòu)上的區(qū)別體現(xiàn)在be動(dòng)詞上?！?/strong>

????? 四、易與現(xiàn)在進(jìn)行時(shí)弄混
　　例：My mother is cooking (cook)when I got home.
　　答案：was cooking
　　解析：這兩種時(shí)態(tài)的共同點(diǎn)是都表示動(dòng)作正在進(jìn)行，但現(xiàn)在進(jìn)行時(shí)前提是現(xiàn)在，而過去進(jìn)行時(shí)前提是過去，由when I got home可看出前提是過去。

　　五、易與一般過去時(shí)弄混
　　例：昨晚我在讀一本故事書。
　　I read (read) a story book yesterday evening.
　　答案：was reading
　　解析：這兩種時(shí)態(tài)的共同點(diǎn)是都用于表示過去發(fā)生的動(dòng)作。但過去進(jìn)行時(shí)強(qiáng)調(diào)動(dòng)作正在進(jìn)行，而一般過去時(shí)則表示過去某一時(shí)間所發(fā)生的動(dòng)作或存在的狀態(tài)，它表示的動(dòng)作往往已經(jīng)完成。“在”說明正在進(jìn)行，而“I read a story book yesterday evening.”的意思是昨晚我讀了一本故事書，言下之意已經(jīng)讀完了。故用過去進(jìn)行時(shí)。
　　另外，在賓語從句中當(dāng)主句為過去時(shí)，從句若是現(xiàn)在進(jìn)行時(shí)，需變成過去進(jìn)行時(shí)。
　　e.g. He said that he was drawing a cat at noon yesterday.

看完以后同學(xué)們是否對(duì)過去進(jìn)行時(shí)有了更全面的了解呢？語法是一塊難啃的硬骨頭，但只要每天消化一點(diǎn)點(diǎn)，拿下它便指日可待。
