自己写了个小短文,错误多多,最好能简单说下为何错了,
Today is Sunday and have no important things.
My classmate ane I take exercise on the afternoon.
First of all,we have plaied badmintoon for one hour.In fact,I think our level is
not bad.Because I have felt very well when I hit every balls.and that I can use left hand
expect for right hand.My classmate is the same as me.
After that We have plaied chinese chess.Actually,we are not often play it.our level
is very low.Even nobody can see us over one minute.most of them only sighed deeply and
waved their heads and then go quick away.I fell some shy...Though we aren't good at
it,but we are good happy.Finally our score is 2:2.
Yeah!we are two happily ...
ps:最后想说臭棋娄子...不知道应该如何说...
