听力材料：
In the next few decades, people are going to travelvery differently from the way they do today. Everyone is going to drive electrically-poweredcars. So in a few years, people won't worry aboutrunning out of gas. Some of the large automobilecompanies are really moving ahead with this newtechnology. F&C Motors, a major auto company, for example, is holding a pressconference next week. After the press conference, the company will present its newelectronically-operated models. Transportation in the future won't be limited to the ground,many people predict that traffic will quickly move to the sky. In the coming years, instead ofradio reports about road conditions and highway traffic, news reports will talk about trafficjams in the sky. But the sky isn't the limit. In the future, you will probably even be able to takea trip to the moon. Instead of listening to regular airplane announcements, you will hearsomeone say, "The spacecraft to the moon leaves in 10 minutes. Please check yourequipment. And remember no more than 10 ounces of carry-on baggage are allowed."
Questions 26 to 28 are based on the passage you have just heard.
26. What will be used to power cars in the next few decades?
正确答案：D
解析：题目询问在未来的几十年中，将使用什么来发动汽车。关键在于听到文章的第2句：“每个人都将驾驶由电力发动的汽车(electrically-powered cars)。”由此可知答案为D。符合短文听力“听到什么选什么”的原则。选项A、B、C在文中均未提及。
27. What will future news reports focus on when talking about transportation?
正确答案：A
解析：题目询问未来的新闻报道在谈到交通时，将集中于哪个方面。关键是要听到“新闻报道将谈到空中的交通堵塞问题”，故A(空中的交通状况)正确。文中说未来的新闻报道中将不再谈及路况和公路上的交通堵塞，故B、C均不正确;文中未提及D。
28. What will passengers be asked to do when they travel to the moon?
正确答案：B
解析：题目询问当旅客去月球旅行的时候，他们会被要求做什么。关键是听懂文章最后一句：“请记住随身携带的行李不能超过10盎司重。”即B(携带的行李要少)。
