【正确答案】热狗和汉堡包是美国最流行的两种食品，你会发现几乎在所有的快餐店都有这两样东西。热狗通常不是用牛肉就是用猪肉，或者猪牛肉，混在一起做的，而汉堡包用的是牛肉。 热狗和汉堡包都是夹着面包吃：热狗用长面包，而汉堡包用圆面包。你可以选择加一些酱和蔬菜进去，不另收费。许多美国人最喜欢的酱是番茄酱，叫做“ketchup”。 你在快餐店点午餐时，如果看不懂菜名并不奇怪，因为连许多美国人也可能看不懂。例如“draw one”是“倒一杯咖啡”的意思；“BLT”是指“夹有咸肉、生菜和番茄的三明治”。 谁也不会指望你懂得这种特殊的字眼儿，你还是照通常的办法点菜。快餐店用自己的特别菜名是为了使点菜更快些。

【答案解析】[解析] Two of the most popular American foods are hot dogs and hamburgers. You will find these available at almost all "fast food" restaurants. A hot dog is usually made either from beef or pork, or a combination of the two, but a hamburger is beef. Both are served on a bread roll: hot dogs on a long roll and hamburgers on a round roll. You have your choice of adding a number of sauces and vegetables at no extra charge. A favorite sauce of many Americans is a tomato sauce called ketchup. When you are ordering your lunch at a "fast-food" place, do not be surprised if you do not understand the food orders -- neither do many Americans. For example, "draw one" means "pour a cup of coffee" ; "BLT" means "bacon, lettuce and tomato sandwich". No one expects you to know this special vocabulary. Order your meal in the usual way. Eating places use their own special words to place an order quickly.
