介绍:
Swallow 燕子
The swallow is a small bird with a forked tail. A swallow-tailed coat is a man's black coat with the lower back part divided into two, looking like the tail of a swallow. It is a formal evening coat.
Swallows spend the summer in the North, then move south to avoid the northern winter. That is the origin of the saying ：“one swallow does not make a summer.” It advises us not to judge by a single instance. If Team Ｂbeats Team A in a match, it does not necessarily follow that Team B is stronger than Team A. Any team may beat a stronger team occasionally.
燕子是尾巴分叉的小鸟。燕尾服是男性穿的黑色上装，后身底部两端分开，看上去就像是燕子的尾巴。它是一种晚礼服。
燕子到北方度过夏天，然后转回南方，以避开北方的隆冬。“独燕不成夏”的谚语，就是由此而来的。它告诉我们不要凭个别事例而做判断。假如乙队在一次赛事中打败了甲队，那不一定是甲队就比乙队强。任何一队都有可能偶然打赢比自己强的队。
