亲,首先不好意思哦.这个我没有办法用定语从句解释
1.你忘记了一个句型吗?
He is as tall as Mike.否定就是He is not so tall as Mike.
同级比较,用在否定句中,as就会变成so
这样理解了上边的句子吗?只是变形而已
2.当先行词是way,且在定语从句中作方式状语时,关系代词可用in which,that,也可以省略.
　　The way (in which/that) these comrades look at problems is wrong.
　　That was the way (in which/that) she worked the problem out.
　　注意：当关系代词在定语从句中作主语时,不省略.
　　例如：I don't know the way that/ which leads to the top of the mountains.
在句子：our teacher（主） studied（谓） foreign language（宾语）.这个句子中不缺主语不缺宾语.缺的是方式状语
