Check pre-exercise

Step 1.Lead-in

T: Now, I am teaching you. You are listening to me carefully.

Ask the students to give me more sentences written in present continuous tense.

Write the structure of present continuous tense on the Bb.

T: But yesterday at this time, I was sitting in my office. (Write the structure of past continuous tense on the blackboard). Underline the different verbs ‘BE’.

Step 2. Presentation

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?

Where’s 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 not here.

Step 3. Practising

Daniel is asking Millie about traveling. Complete the conversation on page 27 with the correct forms of the verbs in brackets. 

Step 4 Presentation

We use for when we talk about a period of time, and we use since when we talk about a time point in the past.

e.g. Mr Dong has lived here for many years.

    Mr Dong has lived her since he was born.

Some verbs, such as come, go, buy and leave, can be used in the present perfect sense, but they cannot be used with for or since in positive statements.

Step 5 since和for的区别

If we want to express a continuous state, we can use another way like this.

Example : begin/start have/has been on

 The film has been on for 20 minutes.

finish/stop   have/has been over
