Martin and Jillion are having their lunch in a restaurant (餐馆). Martin's and Jillion's cars
are outside the restaurant in the car park. Jillion is looking through the window at the cars
and scooters (摩托车).
"I think scooters are 1 (good) than cars," she says.
"They only want a little petrol (汽油), so they are 2 (cheap). And I think they are
3 (easy) to drive."
Martin laughs. "Oh, cars are more expensive (贵的), that's true," He says. "but they're
not 4 (difficult) to drive. And think! Cars are 5 (big) than scooters, so they take
more people. They're 6 (big), but they're quiet. My car is 7 (quiet) than a scooter
or a bus or a plane or a train. Cars are 8 (quiet), and they are 9 (safe) and 10
(warm)."
