     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)."
