英译汉

In 1995 James and Anne-Marie O'Connor decided to open a small shop selling sandwiches in the city center about 4 1/2 miles from their home. They couldn't afford a bigger shop with a kitchen at the back as that would have cost an extra $250 per month and they didn't have enough money. They planned to prepare the food at home and drive it to the shop, a 20-minute journey.

They opened the shop in May and were soon doing very good business selling food to the people who worked in offices in the city. Everything went well for the first 6 months, but then, as the weather got colder, fewer people came into their shop. Takings were down by 15% and they both knew they would go out of business if things didn't improve.

They decided to start selling hot food Anne-Marie prepared it at home and drove it to James at the shop. Everything was going fine until one day Anne-Marie got caught in a traffic.
