题目内容：

Another thing I found very difficult was English grammar
（用 i found 开头的同义句）

优质解答

I found another thing that was very difficult was English grammar
I found another very difficult thing was English grammar

追问：

第一句对么?

追答：

是。I found another thing that was very difficult was English grammar中， another thing that was very difficult was English grammar相当于省略了that的宾语从句， 在这个从句中，主语是another thing, that was very difficult是that引导的定语从句修饰主语； 谓语是was, English grammar 是表语。
