高一英语周周练 班级姓名号次 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 about 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 directly compared. They also enjoy games that move in stages, in which each stage, the choosing 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 puzzled 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 player without having to think whether he is a popular person, and he can find himself being a useful partner to someone of whom he is ordinarily afraid. He becomes a leader when it comes to his turn. He can be confident, too, in particular games, 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 their control. Everyone knows the 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. 1. What is true about children when they play games? A. They can stop playing any time they like. B. They can test their personal abilities. C. They want to pick a better team. D. They don’t need rules. 2. To become a leader in a game the child has to _________. A. play well B. wait for his turn C. be confident in himself D. be popular among his playmates 3. What do we know about grown-ups? A. They are not interested in games. B. They find children’s games too easy. C. They don’t need a reason to play games. D. They don’t understand children’s games. 4. Why does a child like playing games? A. Because he can be someone other than himself. B. Because he can become popular among friends.
