Question

改非谓语动词I was often a little tired after a day's work and watch TV demands very little effort.

Answer 1

原句有语法问题.谓语是"was tired",要改的是"watch".所以整句话应该是：
I was often a little tired after a day's work and watching TV demands very little effort.
把整根句子分开：
I was often a little tired after a day's work
and
watching TV demands very little effort.
如果把句子从"and"这里分开,就可以得到两个完整句.所以要让第二个句子通顺,就要把"watch"改成"watching".这样一来,"watching"作为名词用,就成了"demands"的主语.
希望能有所帮助.
