American eating is funny. People in America eat almost everything with a fork. And it seems that holding
a knife in one's right hand longer than a few seconds is thought to be against good table manners.
The system is that if it is necessary to use a knife, people take the fork in their left hands, and cut off a
piece of meat or others. Then they put the knife down, transfer the fork to their right hands, and then transfer
the food to their mouths with the fork. This is clearly funny, but it is considered good manners.
There are several results of this system. First, if it is not necessary to use a knife, Americans don't use one,
because this greatly complicates (使复杂化) things. Therefore, sometimes they will try to cut things like
potatoes and even bacon with a fork. Second, since only one implement (器具) is being used, food has to be
chased around the plate with the fork. Third, tables are usually laid with one knife and two forks. The outside
fork is for the salad. There is no need for foreign visitors to follow the American system and try to eat the
salad with only a fork, but if you do use your knife, remember to save it for the meat.
