过去进行时主要表示过去某一时刻正在进行的动作,或表示过去某一阶段一直在进行的动作。一起和小编来看一下过去进行时的易错题吧!
    一、丢掉be动词或忘记把动词变成现在分词
  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:现在进行时中“be+现在分词,缺一不可”的规律也可应用于过去进行时。

  二、对动词或动词词组提问时丢掉doing
  例:We were flying kites at 5:00 p.m. yesterday. (对划线部分提问)
  What were you at 5:00 p.m. yesterday?
  答案:What were you doing at 5:00 p.m. yesterday?
  解析:现在进行时中“What……doing……”?句式同样适用于过去进行时。

    三、易把be+现在分词记成be+过去分词
  例:He was talked (talk) to his mum at that time.
  答案:was talking
  解析:过去进行时与现在进行时结构上的区别体现在be动词上。 

      四、易与现在进行时弄混
  例:My mother is cooking (cook)when I got home.
  答案:was cooking
  解析:这两种时态的共同点是都表示动作正在进行,但现在进行时前提是现在,而过去进行时前提是过去,由when I got home可看出前提是过去。

  五、易与一般过去时弄混
  例:昨晚我在读一本故事书。
  I read (read) a story book yesterday evening.
  答案:was reading
  解析:这两种时态的共同点是都用于表示过去发生的动作。但过去进行时强调动作正在进行,而一般过去时则表示过去某一时间所发生的动作或存在的状态,它表示的动作往往已经完成。“在”说明正在进行,而“I read a story book yesterday evening.”的意思是昨晚我读了一本故事书,言下之意已经读完了。故用过去进行时。
  另外,在宾语从句中当主句为过去时,从句若是现在进行时,需变成过去进行时。
  e.g. He said that he was drawing a cat at noon yesterday.

看完以后同学们是否对过去进行时有了更全面的了解呢?语法是一块难啃的硬骨头,但只要每天消化一点点,拿下它便指日可待。
