Tom and I are good friends．Tom is an English boy，but I am a Chinese girl．He is 12 and I am 13．He is in Class One．I’m in Class One，too．
    Tom has a nice soccer ball．He can  play it very well．I have a computer．I can  play computer games，but I can’t play soccer．It is difficult．Tom teaches(教) me to play soccer，and I teach Tom to play  computer games．Now (现在) I can play soccer and Tom can play computer games．
