I went to Shanghai last summer holiday. Have you ever been to Beijing? Yes, I have. Do you want to go there again? Yes, I do. We use have /has been to express the idea that someone went to someplace and has already come back. I have been to England twice. (Where am I now/Am I still in England? ) Millie, can you go to office to bring me the chair? Wheres Millie? She is on the way to the office, or maybe she is in the office. She has gone to the office. And she will come back in a few minutes. We use have /has gone to express the idea that someone went to someplace and is still there.

B: I went there two weeks ago.A: When did you leave Shanghai?B: I left there two days ago.A: How long have you stayed there?B: I have stayed there for twelve days.Work in pairs. Step 2 Presenting We can say: Jim has stayed in Shanghai for 12 days. He left there two days ago. But we cant say: Jim has left Shanghai for two days. Because some verbs, such as come, go and leave cannot be used with continuous time adverbials such as for two hours or since last month. To talk about an action that happened at a point in the past, we will have to use ago and the simple past tense. Step 3 Practising Tell if the following sentences are true or false. 1. He has bought a bike for two years. (F) 2. Millie bought a purse two days ago. (T) 3. She has already left Beijing. (T) 4. She has been away from Beijing for 2 days. (T) 5. She left Beijing two days ago. (T) 6. Simon has joined the Reading Club since 2000. (F) Step 4 Presenting If you want to express a continuous state, you can use another way like this: Verbs Used for a continuous stateborrow have /has kept leave have /has been away join have /has been in /a member of die have /has been dead marry have /has been married come / go /arrive have /has been in /at begin / start have /has been on Step 5 Practising Millie and Sandy are talking on the phone.
