一,make sth done.
常见于“make onesefl undertood / heard”句型,意思是,“使某人听明白/听见自己说的话”,有个特点,主语通常是人,宾语也是主语,所以用反身代词.如：He repeated,but he couldn't make himself understood.“他又说了一遍,但还是不能让人听懂.”She spoke loudly so that she could make herself heard.“她大声的讲话,以便别人能听见.”=She spoke loudly so that everyone could hear her.
二,have sth done
直译是,“让某事被别人做,”意译是,“让/请某人（给自己）做某事”,do的动作是主语以外的人发出,不是主语发出,sth 与do之间是被动关系,所以用了过去分词done.该句型有个特点,就是主语通常是人,而宾语是物.这是一个“主语---谓语---宾语---宾语补足语”的句型,done是做宾语sth的补足语的.
该句型常见于：have my hair cut,have my car / bike / watch / shoes / repaired.
至于这个句型的have是否可以用make代替,比较少见,建议慎用.
