怎么这2个都是正确的吗?suggest sb to do；suggest （that）sb （should）do

suggest sb to do 不正确,英语中没有这种用法,
suggest （that）sb （should）do 是正确的,宾从中必须用虚拟语气 （should）do
如:The doctor suggested he eat less fat .医生建议他少吃肥肉.(that ,should 都省略了)
另外,"建议(某人)做某事" 是:suggest (sb’s/ sb.) doing sth.上句可改为:
The doctor suggested him/ his eating less fat .
