请认真阅读下列短文，并根据所读内容在文章后表格中的空格里填入最恰当的单词。(每空格不得超过1个单词)
Manners in every country are different.  What is polite in China may not be polite in the United States. These basic rules will help you enjoy Western food with your American friends.
Always put the napkin (餐巾 ) on your lap first. Before you leave the table, fold your napkin and put it beside your plate.
Wait until everyone has been served to begin eating. Everyone begins to eat at the same time. The host or hostess may invite you to start eating before everyone is served. Some foods may be cold if you wait until everyone is served. If invited to begin before others are served, wait until three or four people have been served before starting to eat,
When eating something in a bowl, do not leave the spoon in the bowl.  Put it on the plate under the bowl. Do not slurp (出声地喝) the soup. Do not overfill the spoon. Do not pick the bowl up to hold it closer to your mouth. When you have finished your meal, place your knife and fork side by side on the plate. This signals that you have finished eating.
Sit up straight at the table. Bring the food up to your mouth. Do not bend down to your plate.
Cut large pieces of meat, potatoes and vegetables into bite-sized pieces. Eat the pieces one at a time.
When eating noodles, wind (缠) the noodles up on your fork. You may use your spoon to help wind the noodles around your fork. The noodles on your fork should be eaten in one bite（一口）.  It is very impolite to eat half your noodles and allow the other half to fall back on your plate.
Do not lean on your arm while eating. You may rest your hand on the edge of the table.
Some of the rules mentioned here may be somewhat relaxed in informal settings.
The best way to learn good manners is to watch others. Observe the way your American friends eat. In this way, you won’t make mistakes when you are unsure of what to do.
