Unit2 Grammar Learning aims: 1．了解have/has been和have／has gone的用法 2．了解since和for的用法区别 3．了解短暂性动词和延续性动词的不同用法以及它们之间的转换。 【基础知识】 1. have/ has been to 和have / has gone to 的区别： 1)We use have/has been to express the idea that someone went to a place and has already come back. It refers to an experience. have/has been to表示某人曾经去过某个地方，现在人已经离开，不在那了也可能已经回来了。 Eg. Millie and Amy have been to South Hill米莉和埃米已去过南山。 have／has been to后面跟地点名词,主要强调某人的一种经历，可以和表示次数的状语连用。 Eg. I have been to Beijing once.我去过一次北京。 - Have you ever been to the USA?你曾去过美国吗？ - No，never.没有，从未去过。 ( )①How many times_______ you_______ to London since last year? A. have; gone B. have; been C. do; go D. did; went ( )② (2013 .随州)- Jack, I haven't seen your uncle for a long time. - He_______ Shanghai on business for two months. A. went to B. has gone to C. has been in D. has been to 2.) We use have /has gone to express the idea that someone went to a place but has not yet returned. have/has gone to表示某人已经去了某个地方，但现在人还没有回来。可能在去的途中，或者到了当地。反正人没有回来。 Eg. Mr. Green has gone to London. He will be back in two weeks.格林先生去了伦敦。他将在2周后回来。 have／has gone to后面跟地点名词，当地点用副词表示时要省略介词to。 Eg.- Where is your uncle? 你叔叔在哪儿？ - He has gone to the library.他去图书馆了。 -Isn't Daniel in the office? Daniel不在办公室吗？ -No. He has gone to the laboratory.是的。他去实验室了。 ( ) - Where is Mr Li? I have something important to tell him. - You_______ find him. He_______ Japan. A. won't; has gone to B. may not; has been to C. may; has gone to D. can't; has been to 3)We use have/has been in to express the idea that someone went to a place and stayed there for a period of time. 辨析： They have been to Suzhou before. 以前去过苏州 They have gone to Suzhou. 去了苏州 They have been in Suzhou for five years. 他们去苏州5年了He knows much about Suzhou. (不仅去了苏州，而且已经待了5年还没有离开) Mary and her family have been in the USA since two years ago. 玛丽和她的家人自从2年前就去了美国。 （两年前就去美国了，现在还在美国没回来） 【巩固练习】 选择have/has been to; have/has gone to; have/has been in 填空 1.
