     Sport is very popular in England.  In other words  lots of  English people  like  the idea of sport .A lot

watch sport on TV.  But the number who take part in  (参加) sport  is quite  small. On the whole English

people prefer to be fat rather than thin.

     The most popular sport in England is football. Football is pasyed on Saturday afternoon in most towns and the supporters (球迷)of a certain team will travel from one end of the country to the other to see their

teams play. There are four divisions(级别)of the football league. Not surprisingly the best teams are in the

first division. But the best supporters are often in the fourth division. You have to be a good supporter to

watch the fourth division football!

     Many other sports  are also played in  England, such as golf,  in which you try to knock a  ball into a

hole;basketball, in which you try to get a ball through a net(篮筐);tennis, in which you try to hit a ball so

that your opponent(对手) can not hit it. As you see, if the ball had not been invented, there would have

been no sport.

     Actually(其实) , that is not quite true. Athletics(田径)  isn't played with a ball; nor horseracing ( 赛马 ). Perhaps that is why they are not so popular as football!
