Good table manners are back
Candlelight bathes the restaurant guests in a friendly light, the menu is about to be served. Some guests are prepared to eat while others are looking around with nervous glances. Which knives and forks should be used first, and where should you put the napkin(餐巾)?
For a while table manners were "out". Now men and women aged 30 or so are rediscovering the finer points of being polite.
Good manners give a pleasant impression(印象). But how do you eat "properly"? The golden role is to act silently. You should not talk to someone with your mouth full. When eating a five-course meal--a frequent event during the holiday season--guests needn't feel frightened by the variety of knives and spoons before them: you work your way towards the plate from the outside.
Uncertain situations often can be mastered with common sense. For example, many unknown salad(沙拉) greens can be difficult to tell from one another, but you can cut them all with a knife. The napkin remains subject special care. The correct way is to fold it in half and lay it on your lap (膝上).
If you leave your place, you should always place your napkin next to the plate. After the meal is over, both cloth and paper napkins are folded and not thrown onto the plate.
The proper table manners also can serve professional advancement. If a choice has to be made among several people for an important position, the employer may choose to lunch with them. Those who make noise with their lips certainly won't stand a chance.
How would you understand "table manners" in the title?
A.Act properly while eating.
B.Choose proper kinds of food.
C.Eat with knives, forks, and spoons.
D.Fold the napkin neatly all the time.
