Paul wants to help reduce（降低） pollution and smog（煙霧）.

He would like to buy a clean car,something good for the environment.

He is thinking about buying a Texla.

The texla is an all electric car.

It uses batteries（蓄電池） instead of gasoline.

There is no exhaust（排氣）, so it doesn’t pollute the air.

However, the car can’t go very far without rechanging the battery（電池）.

To charge（使充電） the battery,you can plug（插入；塞??；接插頭） it into an electrical outlet（電池插座；出口）.

Recharging the battery takes time.

One of Paul’s friends has one and is quite happy with it.

He says it’s reliable（可靠的，可信賴的） and well-engineered（設(shè)計(jì)的，工程）.

There are also several charging stations near Paul’s office.

So he isn’t worried about that.

The cost for charging the battery is low.

It’s less expensive than buying gasoline.

His wife, Kathy, also likes the idea of buying an electric car.

She likes the idea of driving a clean car.

So it makes sense（有意義；講得通；言之有理）.

（Charging the battery is less expensive than paying for gasoline.）

In the future, there may be driverless cars.

These may be very safe, but Paul doesn’t like them.

He enjoys driving.

He likes to be in control of his car.
