he has (much) work (to be done),(so)he was very busy.括号里那儿错了
问题描述：
he has (much) work (to be done),(so)he was very busy.括号里那儿错了
答
He has much work to do
主语是he，不能用被动语态
答
work 是不可属名次 所以用 much 修饰是正确的，没问题。
to be done 有工作要去“做” 而不是 要去“被做”，所以应该是 “to do ”而不是“to be done” .这里错了。
答
to be done 改为 to do
答
he 《is》 very busy
答
第二个括号是 to do
答
to be done改为to do ，动词不定式作后置定语。
答
to be done 改成to do ,这里用主动表被动
答
(to be done)
应该是he has much work (to do),so he was very busy.
