问答题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。[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.

问答题世界上有许多车辆，造成了许多严重的问题。除了交通堵塞、交通事故和燃料急剧消耗外，车辆对大城市的空气污染也负有主要的责任。车辆每时每刻都要往空气里排放大量的废气。一种可能的解决方法是设计和制造无污染的汽车和燃料。一些公共汽车开始使用天然气，这样的车辆比使用汽油的汽车释放的二氧化碳要少。另一种解决方法是发展现代化的公共交通系统，限制私人车辆的使用。如果汽油的价格持续上升，而公共运输工具还算高效方便，那么大多数人就不会买私人汽车了。总体来说，要消除大气污染需要政府和公众的共同努力。只有通过科学和技术的帮助，这个问题才会解决。[解析] Too many cars have created a lot of serious problems in our world. Besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. All the time, they are pumping huge amounts of waste gases into the atmosphere.One possible solution is to design and develop clean cars and clean fuels. Some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as the petrol.Another solution is to develop modern public transportation systems and restrict the use of private cars. If the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not buy private cars.On the whole, the elimination of air pollution needs the co-efforts from the government and the public. This problem will be solved only with the help of science and technology.
