Translate the paragraph into Chinese. Table manners are the rules of etiquette that should be observed by diners. In the UK, the host or hostess takes the first bite after all food is served and everyone is seated. Food should always be tasted before salt and pepper are added. It is acceptable to take some butter from the butter dish with a butter knife and put it onto a side plate. This prevents the butter in the dish from gathering bread crumbs as it is passed around. It is impolite to reach over someone to pick up food or other items. Diners should always ask for items to be passed along the table to them. Food should always be chewed with the mouth closed. It is rude to eat noisily. Talking with food in one’s mouth is also seen as very impolite. When someone has finished eating, they should place the knife and fork together on the plate and place the napkin unfolded on the table.
