Now here I have three boxes and three cups. Please guess which one is the yellow box. Ask one student to move and mix these boxes. Is this the yellow box?  It can’t be the yellow box or it might be the yellow box. How about this one? Yeah, it may be the yellow one and last it must be the yellow one. Yes, you are right. Let’s read the sentences and try to guess the meaning. It is the yellow box or it isn’t the yellow box. That’s the fact. We can guess it must be the yellow box, Very very very sure. Or it may be, a little sure;  it might be, not sure。Could not be or it cant be no. We can use model verbs to express the possibilities.OK, must必须，have to. Must refers to Self need. Have to refers to outside requirement. And how about should and ought to? Yes 应该。Should equals must, referring to self need. Ought to equals have to, referring to the outside requirements. okay now do some practice.Fill in the blanks. Okay first one should,  go on ought to,  next one have to, last one must.

We know should do/ ought to do refer to the time now or in the future. How about the past time? we can use should have done or ought to have done. OK, pay attention, should or ought to have done. Now let’s come to the sentences in the text. OK read together: He should have known that the police would never allow that sort of thing a police men approached Jimmy and told him all to have gone alone a side Street as jumbo was holding up the traffic. yes should have known, yes he should realize that that thing at the very beginning but he didn’t.  and Jimmy should go along a side Street at very beginning but he didn't.

Practice

  Let’s come back to the question at the beginning. How many times does the players wearing white pass the ball.  Let’s watch it again. So how many times? The correct answer is sixteen passes. OK more questions for you. first how many players are there at last? Six? Four ? Question Two: can you see a gorilla among players? Yes? No? Question three: what color is the curtain at first how about the curtains color later? Let’s watch it again. Yeah how many players at last? There were five. Can you see a gorilla? Yeah!  The cotton? At first, it is red and later it turns to gold.

Let’s try to use the expressions should have done or all to have done.The first one :I should have noticed the gorilla. Two, I ought to have seen a player where with the black T- shirt leave and three  I should have known the color of the curtain changes red to gold.

Now here can you describe the experiment the monkey business illusion and share your opinions. At least seven sentences.  You can use the key words should/ ought to have done ,  gorilla, curtain. Yes, very good!
