Hello, I was once a hostess. Now I am on my first bus trip and I’m quite surprised at the services offered during the trip. Included the meals on the way, rest rooms and public-address announcements. Just now, I introduced myself to the hostess on the bus, and we told each other about experience on air and ground travel.
At lunchtime, she gave out menus offering a choice of sandwiches. As she starts filling orders, she found that there weren’t enough egg-salad sandwiches. She quickly went to whisper to the driver. The bus soon stopped. The hostess ran to another bus that was all the time following ours and soon she returned with a box of egg-salad sandwiches. As she passed my seat, she asked, "Could you do that on a plane"

[单项选择]Naturally the young are more inclined to novelty than their elders and it is in their speech, as it always was, that most of the vocabulary changes originate. But listening critically to their talk I hear hardly my new words. It is all a matter of using old words in a new way and then copying each other as they wish to speak differently from their parents. They want even more to speak like people of their own age. A new usage once took time to spread, but now a pop star can flash it across the world in hours.
Of course, it is not only the young who like to use the latest in-word. While they are describing their idols as smashing, great, or cosmic (宇宙的), their parents and the more discriminating of the younger set are also groping for words of praise that are at once apt and fashionable. However, their choice of splendid, brilliant, fantastic and so on will in turn be slightly dimmed by over-use and need replacement.
Magic is a theme that has regularly supplied words of pr
A. they lose their freshness
B. there are more words available in this area
C. young people are becoming more discriminating
D. older people try to avoid the in-words of the young
