I will share a true story that happened a couple of days ago to you. One of my classmate bought a bag of snacks from a food store. A few roommates were then invited to enjoy snacks. Unluckily, all of them got poisoned and had a stomachache with our faces pale. They were quick sent to a nearby hospital. Doctors examine them and gave them some medicine. They were out of dangerous soon before taking the medicine. This accident should make us to realize the seriousness of the food safety. I strongly suggest that the whole society pays more attention to this problem.

6 . In a great many cities, hundreds of people ride bicycles to work everyday. In New York City, some bike riders have even formed a group called Bike for a Better City. They declare that if more people rode bicycles to work, there would be fewer automobiles(汽车) in the downtown part of the city and so less dirty air from car engines. For several years this group has been trying to get the city government to help bicycle riders. For example, they want the city to draw special lanes(通道) for bicycles only on some of the main streets, because when bicycle riders must use the same lanes as cars, there are accidents. Bike for a Better city feels that if there were special lanes more people would use bikes.

But no bicycles lanes have been drawn. Not everyone thinks it is a good idea—they say it will slow traffic. Some store owners on the main streets don't like the idea—they say that if there is less traffic, they will have less business.

The city government has not yet decided what to do. It wants to keep everyone happy. On weekends, Central Park—the largest place of open ground in New York—is closed to cars, and the roads may be used by bicycles only. But Bike for a Better City says that this is not enough and keeps fighting to get bicycle lanes downtown.
