问题描述：
He failed his math examination because of his carelessness.
failed 后为什么没有in?
答
这题考查的是动词fail的用法。
注意：遇到动词，就要关注及物，不及物的问题。
fail 考试不及格时是及物动词，直接加宾语就行。fail the exam\test
未能做到某事等不及物，需要加介词后，才能加宾语。fail in my goal
fail to get it
fail in his duty
这是fail的用法。记住吧！
答
你想的应该是fall in吧
fail在这里是没有通过的意思可以用做及物动词不用介词啊(failed是过去式)
答
考试不及格一般用fail an exam
答
我觉得应该加in。
fail 是一个不及物动词。
如果不针对具体的事情，就不用加 in
eg：I failed.
You will fail if you don't work hard.
如果指具体的事情或者场合就需要加 in
eg: He failed in the sports meeting.
She failed in her attempt to convince him.
我觉得应该加in
