阅读下面短文,回答文后的5个问题,并把答案写在答题卡指定区域内。

[1] If you read a newspaper or listen to a newscast(news report) recently, you may hear or read a strange word, “staycation.” Staycation is a new word the American press(newspapers, radio, and television) is using to describe a vacation very close to your own home, or simply staying at home during your vacation. It is a combination of the words “stay” and “vacation”.

[2] According to many news reports, these staycations are very popular among American families this year. Why? The high price of gasoline for cars and airplanes has made it very expensive for Americans to travel compared to past years. When you combine this with the weak American dollar, it all adds up to people deciding to stay close to home during their traditional summer vacations. Of course, some places are more interesting to “stay home at” than others. And if you live in a very small town, well, you may just want to skip your vacation and save your time up to next year!

[3] Everything is expensive nowadays, and let’s face it—a vacation just may not be in your plan this year. You don’t have to give up family fun just because you can’t              ; instead, follow my tips for an economical staycation filled with old favorites and new adventures!
