Dialogue 1

M: How do you usually get to school?

A: I usually ride my bike. Which form of transport do you prefer to use?

M: I feel that I can see more when I pedal a bicycle, but when I feel lazy, I drive my cat.

A: I think we should discourage people from using their private cars. They produce too much pollution!

M: I agree, but I would find it difficult to stop using my car. It's just so convenient.

A: Cars might be convenient, but they're so bad for the environment.

M: Do you have a car?

A: No. I used to have one though. Once I started using my bicycle to get around, I found that I didn't really need it.

M: Maybe if I sold my car now, I wouldn't be so tempted to use it.

A: You could try. It would save you a lot of money.

M: That's true. Every month, I spend hundreds of dollars on gas, insurance, and repairs.

A: If you got to class by riding a bicycle every day instead of driving, you will get lots of exercise, too!

M: I could stand to lose a few pounds. Having a car has made me lazy. I never end up walking anywhere!

A: Let's go to a car dealership. I'll help you try to sell your car for a good price.

M: Sounds good! Let's go!

Dialogue 2

A: Are you ready to go the concert?

M: Yes. Should we go there by bus so we aren't late?

A: Actually, why don't we go there by bike? We could get stuck in traffic if we travel by bus in rush hour.

M: That's true. Cycling is good for our environment, too. Let me just get my helmet then.

A: Is your helmet comfortable?

M: Not really, but I liked the design, so I got it.

A: Maybe you should think about getting a round helmet; they're better.

M: I'll think about it.

A: Is that your new bicycle?

M: Yes, my father gave it to me for my birthday. Do you like it?

A: It's the newest 10 speed cycling mountain bike. These are really expensive!

M: Nothing but the best from my dad. I like eveything about it except for the brakes. They're a bit sticky.

A: I can fix those for you. Is there anything else wrong with it?

M: Well, my saddle is too low for me. Do you know how to change the height?

A: That's easy. It's important to have the saddle high enough so that your legs can extend fully when you're on your bicycle.

M: Is that why my knees have felt sore after every time I've ridden my bike?

A: It's possible Give me a minute and I can fix these for you and then we can go.
