Sports and games make our bodies
strong, prevent us from getting too fat, and keep us healthy. But these are not
their only use. They give us valuable practice in making eyes, brain and muscles
work together. In tennis, our eyes see the ball coming, judge its speed and
direction and pass this information on to the brain. The brain then has to
decide what to do, and to send its orders to the muscles of the arms, legs, and
so on, so that the ball is met and hit back where it ought to go. All this must
happen with very great speed, and only those who have had a lot of practice at
tennis can carry out this complicated chain of events successfully. For those
who work with their brains most of the day, the practice of such skills is
especially useful. Sports and games are also very useful for character-training. In their lessons at s A. its members B. its team work C. the football field D. the climate [简答题]请简述施工人员的进站规定。

Teaching children to read is not passing reading on to them. It is certainly not endless hours spent in activities about reading. Douglas insists that "reading cannot be taught directly and schools should stop trying to do the impossible."
Teaching and learning are two entirely different processes. They differ in kind and function. 7he function of teaching is to create the conditions and the climate that will make it possible for children to devise the most efficient system for teaching themselves to read. Teaching is also a public activity: It can be seen and ob served.
Learning to read involves all that each individual does to make sense of the world of printed language. Almost all of it is private, for learning is an occupation of the mind, and that process is not open to public serum.
