fail可作vt也可是vi⑴当为vt时，形式为A fail B，意思为A使B fail 了。举例：The teacher failed me in mathematics.老师给我数学不及格。When I wanted his help he failed me.当我需要他帮助时, 他却使我失望。（注意这儿fail解释为“使失望”）⑵当做为vi时，形式为A fail。举例：I failed in my English examination。我的英语考试不及格。（不加in也行，至少我习惯加了。）He failed to come.他未能来。当然，fail还有别的意思：The patient's heart failed.病人的心脏停止了跳动。P.S：fail还可做名词，意思为“失误 ， 失败者[尤指考试落第者]”。
