試題詳情
"Americans are not as fit as they think they are，"says Dr.Moginnis of the US Department of Health and Human Services.That should come as a surprise，because in the US，fitness is something you cannot get away from.You'll see special stores full of books and cassettes telling you how to keep fit，You'll meet joggers in the park，and find at least one health club in every town.
But the figures（數(shù)字）don't look so good.More than 30 percent of Americans smoke，and 80 to 90 percent still don't get enough exercise.The situation is worse among children，who spend too much time watching TV，and too little time running around.The American diet，too，is less than perfect.Quick，ready-made food usually contains too much fat，salt and sugar.And as usual，it's the poorest families who eat the worst food.Eating well means spending what they don't have-more time and more money.Americans know that they have fitness problems.Many people feel they are too fat，even if their doctors don't agree.And 80 percent of people say they try to improve their fitness，even if they soon give up.

1．Passage A
Many of us have read stories or seen films about space-creatures.They come to Earth in spaceships that look like flying saucer（飛碟）.These space-creatures do not look like human beings at all，but they are usually very intelligent（聰明）.In one film，they were tiny little men with large heads.When they landed on Earth，they knew exactly what to do.They went straight to the President's palace and made him their prisoner！
The stories about space-creatures are，of course，not true.Space-Creatures exist only in story-books and in films，just like giants（巨人） and fairies.
