We think we should do whatever we can to help our school.该句中whatever可以换成everything吗?我知道“we should do whatever we can to help our school” 从句做we think的宾语；whatever引导的是名词性从句,那么everything的话可以是定语从句也能解释吧?我觉得句意不会受影响.像这句we should do everything we can to pritect the environment.正确的话,我那句话不可以用everything吗?
we should do everything we can to protect the environment.刚才打错单词。
我晓得了。因为这是试卷上的填空题，有人说定语从句的话一般只考关系词，不会要求填先行词。确定了我的判断没错就好。Thank you！
