Exercise 3. Read and learn. в косвенную речь пожалуйстаааа Tom: Are you going to attend the seminar tonight? Bill: I should go. Unfortunately, I won't be able to do so. Т.: Why should you go there? В.: The speaker will talk about composite ceramics. I must know all about this subject. As you know, I'll do some experimental work in this field next June. So I'll have to know about it. Т.: In that case, you ought to cancel (отменить) your other plans and attend the seminar. You shouldn't miss (пропускать) it. В.: You are right. But I can't go. Т.: Why can't you? В.: Don't you remember (помнить)? We are to take an exam in French tomorrow. I have to study for the examination. T. Do you have to study? Is it a necessity? В.: Well, I suppose the expression «have to study» is too strong. No one is forcing me. But I really ought to study tonight. Shouldn't you do it too? Т.: I don't have to study. I studied last night and I am sure I can pass it. Besides that, I must attend the seminar. В.: Why must you attend it? Т.: Have you forgotten? I must introduce the speaker to the audi¬ence. В.: Yes, that's right. Т.: Well, I have to go now. I may be late. I'll see you later.
