ROLE PLAY AT A CHEMISTS
1. Read the dialogue between a pharmacist and a visitor of a chemists and explain what problem the visitor has.
- Can I help you?
- Yes, please. Can you give me something for my insomnia?
- Have you got a prescription?
- No, Im afraid not. You see Ive been so busy the whole week.
- I see. You may be a bit overstrained then. Still you must have a prescription for most hypnotic drugs weve got, since they are very potent.
- Can you recommend some herbal medicines that must be dispensed without a prescription?
- Well, you may try Energetine of Valerian, but I should warn you it may cause headaches and heaviness in the head in large doses.
- OK. Ill be very careful. Thanks a lot. Just one more thing. Must I take it before meals or after meals?
- At least a quarter of an hour before meals as it can interact with some foods. Follow the instruction on the label and remember, if you dont feel better soon, you have to consult a doctor.
- Sure. Good-bye.
- Bye.
2. Imagine that you are also at the chemists and make your own dialogue using the vocabulary youve learnt and modal verbs.
