The willful blindness  in hockey toward concussions (头部撞击) has dropped. Hockey Canada has followed the lead of USA Hockey in preventing bodychecking (身体拦截) below age 13. A bad head injury of Sidney Crosby, the hockey's greatest star, opened the eyes of hockey people everywhere. This country's children have been facing similar danger at early ages, and Hockey Canada had to deal with a deep worry in the minds of Canadians to make the rule change. The liking for bodychecking from an early age is part of what makes Canadian hockey what it is.

 The change in rules should be taken as a chance to draw special attention to skill development in an environment free of danger.  It may also control the loss of thousands of young players who don't enjoy that environment.

 For years, many Canadian hockey parents and coaches have insisted that bodychecking at early ages is necessary to ensure that players can do it safely at older ages. True or not, there may be a safer way to teach hitting than to make younger players pay a price for it in head injuries. When USA Hockey changed its rules for the 2011-2012 season, it also created bodychecking-education programs that will be mandatory(强制的) for all coaches,  including those teaching players in  the pre-checking ages. And it began to encourage more "touch" - without real bodychecking - from 9 t0 12. It also made the rules for 13 and up stricter. The USA is trying to show that it's possible to teach hockey protective skills without putting11 and 12-year-olds in greater danger. It's worth the try.

 Hockey Canada has taken serious steps to do away with hits on the head. However, it's hard to change a sports culture so connected with who we are as a country. Too often, bodychecking has been used to try to separate a player from his head rather than from the ball. Children were paying a price for this country's love of the game.

 There are always changes in Canada's game, and the change in the bodychecking age sends the clearest message yet to coaches and parents that player safety is paramount(至上的) in the game.

Time to Dance

Are you the kind of person who likes to move with music? It's a natural thing to do. Even little children start jumping up and down when they hear music.

Scientists say that animals dance, too
39．. The "dances" of animals send messages to other animals. But when people dance, they express feelings about life and love, or about these very human experiences.

Dances are good for you in many ways. For one thing, dancing is good for you physically. It makes your heart work and makes you breathe fast.
40．. If you go dancing often, you can keep physically fit. You may feel very tired after dancing, but you'll probably also feel relaxed and happy. This is another important point about dancing. It gives you a chance to express your feelings and feel better about yourself
41．, dancing helps those feelings go away.

42．Some dances are for couples and some are for groups. But all kinds of dances give you a chance to meet new people or to do something enjoyable with friends.
