The game of Go (围棋) is an important board game with origins in China from more than 2, 500 years ago. In China, Go 【小题1】 (recognize) as “hand conversations” as well, through which players communicate with each other. 【小题2】 other words, they “talk” through the placing of pieces on the board. The metaphor (暗喻) first 【小题3】 (use) by Zhi Daolin, reflects the nature of the game. While scholars of his time often lost 【小题4】 (they) in philosophical (哲学的) debates on life and universe, he preferred to play Go, 【小题5】 he believed was full of hows and whys of life.

Master Go players often feel as if they were playing a real-life game; sometimes one can move forward, while at other times, one must slow down; sometimes one can 【小题6】 (direct) face the challenger, at other times one must take an indirect approach. Appropriate placement of each tiny Go piece is similar to 【小题7】 one might solve a difficult problem of life. The purpose of 【小题8】 (play) Go is not just to win but also, more importantly, to seek 【小题9】 (wisdom) through the process. The players unite with each other on the board. Instead of fighting as 【小题10】 (enemy), they cooperate to play a good game. One thoughtless move could ruin the enjoyment.

Children have their own rules in playing games. They seldom need a referee（裁判）and rarely trouble to keep scores. They don’t care much 【小题1】 who wins or loses, and it doesn’t seem to worry them if the game is not finished. Yet, they like games that depend a lot on luck, so that their personal abilities cannot be 【小题2】(direct) compared. They also enjoy games that move in stages, in which each stage, the 【小题3】(choose) of leaders, the picking-up of sides, or the determining of which side shall start, is almost a game in itself.

Grown-ups can hardly find children’s games exciting, and they often feel 【小题4】(puzzle) at why their kids play such simple games again and again. However, it is found that a child plays games for very important reasons. He can be a good 【小题5】(play) without having to think 【小题6】he is a popular person, and he can find himself being a useful partner to someone of whom he is ordinarily afraid. He 【小题7】(become) a leader when it comes to his turn. He can be confident too, and in particular 【小题8】(game), that it is his place to give orders, to pretend to be dead, to throw a ball actually at someone, or to kiss someone he has caught.

It appears to us that when children play a game they imagine a situation under 【小题9】(they) control. Everyone knows 【小题10】 rules, and more importantly, everyone plays according to the rules. Those rules may be childish, but they make sure that every child has a chance to win.
