[简答题] "Fingers were made before forks." When a person puts aside his knife and fork, and dives into his food, someone often repeats that saying. The fork was ancient (古代的) agricultural tool, but for centuries no one thought of eating with it. Not until the eleventh century, when a young lady from Turkey brought her fork to Italy, did the custom reach Europe. By the fifteenth century the use of the fork was widely spread in Italy. The English explanation was that Italians hated eating food touched with fingers. English were thought to be womanlike and women who used them were called show-offs (卖弄) and overnice(过于讲究的). Not until the late 1600s did using a fork become a common custom. The custom of eating with a fork was ______.
