B. Under the water.
C. In the sky.
【正确答案】 C
【答案解析】[解析] 17-20
In the next few decades people are going to travel very differently from the way we do today. Everyone is going to drive electrically powered cars. So in a few years people won't worry about running out of gas.
Some of the large automobile companies are really moving ahead with this new technology.
Transportation in the future won't be limited to the ground. Many people predict that traffic will move to the sky. In the coming years, instead of radio reports about road conditions and highway traffic, new reports will talk about traffic jam in the sky.
But the sky isn't the limit. In the future, you'll probably even be able to take a trip to the moon. Instead of listening to regular airplane announcements, you'll hear someone say, "The spacecraft will get rid of the gravity in ten seconds. Please check your equipment and remember, no more than ten ounces of carry-on baggage are allowed."
