这句话是病句吗？如果是，请帮我改正。

这句话病得太厉害,都看不出想表达什么,干脆贴出中文吧
我猜测中文是,这些孩子除了看电视就是上网,基本没有亲戚来和他们一起庆祝春节,只是时不时得来探望他们一下
如果是上面的意思:

These children just watch TV and play computer games for all days. Almost no relatives come to celebrate Spring Festival with them, most of them just visit them occasionally.

是病句，也太长
I always prefer short sentences. This is easier to understand. The sentence also looks neater. Try to break your long sentence to smaller sentences

The children can only watch TV and play computer games. There is almost no relatives to visit them except during the spring festival party

口袋蓝灵, Do you find it neater and smoother when you read these two shorter sentences?

almost no relatives hold spring festival party, so the only thing for the children to do is to visit them in time except watching tv and playing computer games.
