(2)could 也可以表示委婉、客气地提出问题或陈述看法,此时可以与 can 互换使用,但 could 的语气较 can 委婉,两者没有时态上的区别。 When I was six years old, I could draw, but I couldn’t write. 当我六岁的时候,我会画画,但我不会写。 小练笔 选择题 ( )1.

They ______ (not could) find their cat last night. 1. 答案:B,根据“When I was five years old”可知,句子说的是过去的能力,要用can的过去式could ,A选项can是一般现在时,C选项am able to也是一般现在时,所以选B。 2. 答案:B,由“when you were a child”可知,询问过去是否具备某种能力,用could ,A选项Can是一般现在时,C选项Are不能与动词原形swim搭配来表示“能游泳”,所以选B。 3. 答案:B,“she said”表明主句是一般过去时,从句中“when she was young”也表示过去的时间,所以要用could ,A选项can是一般现在时,C选项will表示将来,所以选B。 4. 答案:could,“when he was a student”表示过去的时间,这里表示过去具备的能力,要用can的过去式could。 5. 答案:couldn't,“last night”是过去的时间,could的否定形式是could not ,可以缩写为couldn't。 点 拨 高频易错点03 Twenty years ago, Mr Brown wrote letters to his friends.(P36) (1) wrote是write的过去时 write sb. a letter = write (a letter) to sb. 写信给某人 I often write my e-friends a letter. = =I often write a letter to my e-friends. 我经常写信给我的网友。 (2)ago是副词,与表示时间的词组连用,表示“……以前”。如: long long ago 很久以前 two days ago 两天前 five years ago 五年前 a moment ago 片刻之前 (3)含有ago的时间状语一般与动词的一般过去时连用。如: Six years ago, I couldn’t write. 六年前,我不会写字。 Ten years ago, he wrote letters. 十年前,他写了信。 易错点提示 ago和before的异同点 相同点:两者均可表示在多久时间“以前”(要放在表示一段时间的词语之后)。 不同点: ago从现在向前回溯,即现在的过去,因此通常与一般过去时连用; before则从过去向前回溯,即指过去的过去,因此通常与过去完成时连用。 I bought the computer two years ago. 我是两年前买这台电脑的。 He said they had left five days before. 他说他们五天前就离开了。 小练笔 单项选择 ( )1. —When did you visit the museum? —______ .
