Intend to do 的固定搭配,发出者必须是人
所以rule is intended to
"rules intending..." is incorrect, since the rules aren't intending to do anything. rules don't have intentions, although their authors do.
this is a passive type construction. the rules are intended to do x, y, and z, so you need "intended", not "intending".
C选项:Correct. 本选项在语法和逻辑上均是正确的。just as…so…是一个连词,so后面相当于主句,也可以将so去掉,直接加主句。
like错误不能加从句,like是介词
A选项:like是一个介词,未划线部分还有一个连词so,这两个词使得整个题目没有主句。
