dont trust such people as praise to your face but speak ill of you behind your back

题目

dont trust such people as praise to your face but speak ill of you behind your back
我知道这里是SUCHAS 结构
可是啊,用who 为什么就错了叱?

答案

don't trust the people who praise to your face but speak ill of you behind your back.这样就可以用who引导了.
SUCH AS 结构和从句有重复,只能用一种.
