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.
