They left us a lot of problems to solve

问题描述:

They left us a lot of problems to solve
left可以用remained替换吗?不行的请说下原因
will remain the chief means of exchange of ideas.这个remain后是跟了宾语吗?

1 left不可以用remained替换,因为remain是不及物动词,后面不能跟宾语!
这句话是主谓形式,the chief means of exchange of ideas remain.由于主语太长,进行提问时,把主语放到了后面,保持句子平衡,“思想交流的主要意义要保留么”
