Unit 1 Diesel and Gasoline Cars

Listening Comprehension

If you have a car, it probably uses gasoline. But why not try a diesel car? Many
trucks use diesel fuel. As gasoline prices rise, diesel cars look good too. Diesel
cars run well. They also are better for passing other cars on the road. Diesel
engines last longer than gasoline engines, too. Diesel cars even keep their value
longer. This is because diesel engines do not wear out as fast as gasoline engines.

On the other hand, diesel fuel is smelly. Also, diesel engines need lots of oil
changes. Oil for diesel cars costs more than oil for gasoline cars. Besides, diesel
fuel causes air pollution. But cleaner diesel fuel is on the way. So, both kinds of
cars have good points. Which sounds better to you?
