سؤال ۱۶، زبان انگلیسی ۳، دی ۱۳۹۸

متن زیر را بخوانید و به سوالات به صورت خواسته شده پاسخ دهید.Many countries now think that cars that burn fossil fuels should be replaced by electric cars. Electric cars don’t burn gasoline in the engine, so they don’t make the air dirty and unclean. They use electricity stored on the car in batteries.

The electric car is usually plugged in at night. The car can be plugged into a special charging unit even at houses. Some electric cars can be plugged right into a regular electrical wall outlet. Others need a larger outlet, like the kind that a stove or a vacuum cleaner plugs into.

The engineers are trying to make better batteries that hold more energy and last longer. To overcome the problem of charging electric cars, hybrid cars are also available. Hybrid cars combine the benefits of gasoline engines and electric motors. They can be designed to meet different goals, such as better fuel economy or more power.
