(right) i bought this book in shanghai, i have had it for three years. 表示“曾经到过某地”，要用have(has) been to，不能用have(has) gone to e.g. where has he been?(他已经回来) where has he gone?(他现在不在这里) have(has) got在形式上是现在完成时，在意思上却和have(has)相同 e.g. have you got(=do you have) a time table?3)现在完成时和一般过去时的区别这两个时态都谈已发生的事，主要差别是现在完成时表示的动作与现在有关,或者对现在有影响，或谈现在之前一段时间里发生的事；而一般过去时单纯谈过去的事，与现在没有关系。因此，凡是有过去时间状语，只能用过去时。 e.g. she was here a minute ago.现在完成时用于提供新的信息。因此，两人对话时，往往先用完成时，如果继续谈到具体的事情、时间、地点，须用一般过去时 e.g.对话： have you milked the cows yet? yes, we have done that already. well done! when did you do that? we did it an hour ago.3 过去完成时1)过去完成时的构成 “助动词had+过去分词”，疑问式将had提前，否定式在had后加not2)过去完成时的用法表示在过去某一时间或动作之前已经发生或完成了的动作或状态 e.g. he had left when we arrived there.用于宾语从句中 e.g. i thought i had seen her somewhere before.4 时态的呼应在主从复合句中，有些从句中的谓语动词时态受到主句谓语动词时态的影响，这种情况叫时态的呼应1)主句若是现在时态或将来时态，从句可以表述任何事态的事e.g. i hear you have learned by heart 5,000 english words.ill tell you which hotel i shall stay in.nobody knows why she didnt come to work for a week last month.2)主句若是过去时态，从句可以表述一般过去时、过去进行时、过去将来时或过去完成时的事 e.g. mr. brown told me he wanted to buy a japanese toyota car.she didnt tell me what she was doing then.he asked me whether i would go abroad in several months.step 1. dictition have the students read the words and phrases in unit 1, the have a dictition.step 2. work in pairs . do activity one .归纳总结1)过去进行时的构成 “助动词be的过去时形式（was，were）+主要动词的现在分词”2)过去进行时表示过去某一时刻或某一段时间正在进行的动作，句中往往有表示过去的时间状语或上下文表示过去某一特定时刻句中的过去时间状语往往是：this time yesterday，from 2 to 3 yesterday afternoon，at 10 last sunday night，at that time，the
