一个英语定语从句问题为什么the package that/which you are carrying is abou

因为,that / which后的从句中you是主语;
如果不是,那么,that / which后面应直接加动词,此时,that/ which就作主语.
例:
the package that/which you are carrying is about to come unwrapped
1.Is he the man who/that wants to see you?他是那个男人想见你?（who/that在从句中作主语） 2.He is the man whom/ that I saw yesterday.他就是我昨天见的那个人.（whom/that在从句中作宾语）

that/which指代the package。
the package that/which you are carrying为主语部分
但是在这一主语的正常语序为you are carrying the package，还原后that/which指代的the package在主语部分中做宾语。

因为在正常的语句中是 you are carrying a package. The package is about to come unwrapped.
package 是carry的宾语

宾语

对呀！还原就是you are carrying the package
