Speaker Opinions on Coffee:

• Speaker A: It's unhealthy, but in my opinion, one cup will do me no harm. I believe on the contrary, after a cup of good coffee, I feel I have enough power to change the world for the better.
• Speaker B: I love coffee. When I shop for food, I always go to a small coffee stall in the supermarket and smell all the kinds of coffee that one can find there. There is coffee with chocolate, coffee with different fruits, coffee with anything. There is also green coffee, an exotic, expensive kinds of coffee as well. I would like to try all kinds of coffee which they sell there, because they have coffee for any weather or occasion.
• Speaker C: Coffee is incredibly tasty and may be a good source of energy in the morning, but I don't drink it. I've read that coffee makes your blood pressure high and can give you a strong headache. It can also cause problems with your stomach and some other illnesses as well. So a cup of coffee in the morning is certainly tempting.
• Speaker D: But still, no thank you. I avoid drinking coffee because I take care of my health. Besides, coffee is very expensive.
• Speaker E: I don't know why many people think that coffee is unhealthy. Well, anything can be unhealthy if you eat or drink too much of it. Even fruits and vegetables can do you harm. However, doctors say that drinking coffee is actually good for you, as it improves your mood and stimulates your body. They also believe that a cup of coffee a day helps prevent heart problems. That's a good reason to drink coffee in reasonable quantities.
• Speaker ?: Then. The. Your hands. We go back to. For the future.
