But according to Pew Research Center, more than 24 million adults don't want to stop using gas-­powered cars. They say electric cars are expensive and charging（充电） them is a problem. We asked some younger people what they think. Period 4　Section B(2a－Self Check) 综合能力训练 Electric cars are better for the environment. It can reduce the air pollution. Some people think electric cars are expensive. But their prices are coming down. Compared with gas-­powered cars, electric cars are more energy­-saving. Anyway, I think we're going to run out of gas at some point. This will make electric cars a necessity（必需品）. Finally, electric cars are smaller and easier to park. —From Henry, 17 Period 4　Section B(2a－Self Check) 综合能力训练 I don't think all cars should be electric. First of all, charging stations are less common than gas stations, which makes electric cars a lot less convenient for long trips. What's more, it takes more time for electric cars to get charged. Electric cars are also more expensive than gas-­powered cars. Finally, they are slower than gas-­powered cars. They are also very quiet. This means that some people cannot hear them when they drive by. These people may not think a car is coming. They have to be careful. —From George, 18 Period 4　Section B(2a－Self Check) 综合能力训练 I think we should all have electric cars, because this is good for the environment and allows us to breathe better. Cars that run on gas make the air dirty. The dirty air is not good for people, animals or trees. Some electric cars are more expensive. But they need less maintenance（保养） than gas-­powered cars. So the costs start to even out. —From Cathy, 18 Period 4　Section B(2a－Self Check) 综合能力训练 1.
