(The) American eating is funny.
They (eat) almost everything with a fork,and it appears that(删掉了) holding a knife in one's right hand longer than a few second is considered to be against good table manners.
The custom is that if it is absolutely necessarily to use a knife,people (should) take the fork in their left hand,(and) cut off a piece of meat in the normal way.
Then they put the knife off ,pass the fork to their right hand,and only then do (they) transport the food to the mouth.
This is clearly funny,and it is considered (as) good manners.
Tables are generally (laid) with one knife and two forks,and the outside fork is for the salad.
(There) is no need for foreign visitors to follow the American (customs) and try to eat the salad with a fork.
