题目内容：

英语句子：We hope to have more time to practise some knowledge that we often make mistakes and
We hope to have more time to practise some knowledge that we often make mistakes and more important.
老师说,这里不能用that,因为that后面的we often make mistakes是一个完整的句子,that没有充当主语或宾语,同时后面的 and more important有些突兀.那正确的句子该怎么改正啊?在原基础上,进行最小幅度的改动.

优质解答

We hope to have more time to practise some knowledge (in which) we often make mistakes.
这里把that换成in which,相当于把你的关系副词换成了代词.
另外,其实that后面不一定要接一个句子.I love music that has a rock core.这种句子也没有错.
希望可以符合你老师的要求吧.
如果对你有帮助,望采纳.
另外不知道您这个more important突然加在后面是想表达什么,希望说的明确一点

追问：

more important指的是some knowledge are more important

追答：

这样的话就去掉and把more important放在前面就会通顺了。

We hope to have more time to practise some more important knowledge in which we often make mistakes.
