There is nothing but English lag me 语法对么

题目

There is nothing but English lag me 语法对么
There is nothing but English lag me
There is nothing but English lags me
There is nothing but English lagging me
这是一个主语从句还是定语从句
（there is nothing but English） lags me
还是 there is (nothing but English which is lagging me )

答案

正确的句子：
There is nothing but English that is lagging me.
=There is nothing that is lagging me but English.
that 引导一个定语从句,先行词为 nothing ,“that”不可改成which.
