1.examination 2.test 3.exam有什么区别

exam 考试,如:school exam
examination 1.考试(此时=exam) 2.检查,如:medical examination 医疗检查
test可以用来指考验,如:She left her purse on the table as a test of the child's honesty.
也可以指严峻的考验,如:That's a real test to me.对我是不小的考验
医疗检查(此时=examination),还可以是小测验
语气上exam,test比较口语,examination比较正式
