however可以放在句尾吗如题

貌似不可以

可以,但是在口语中,正规的书面语不可以

However,most of the time,people from the two countries do not have any difficulty in understanding each other.尽管如此,大多数时候,两国人在互相理解上没有困难.
however adv.（in spite of this,nevertheless）尽管如此,可是,仍然.
注意however作副词时可以放在句首、句中或句尾,但要用逗号隔开.例如：
It's raining hard.However,I think we should go to school on time.雨下得很大,我仍然认为该准时上学.
She waited,however,for no answer.然而她没有等来回答.
The students thought they had done everything as the teacher did.They were mistaken.however.学生们以为他们按老师做的那样做了每件事,然而他们错了.
注意however 的语气比but强,与 but不同的地方还有它可放句首、句中或句尾,而且注意要用逗号（however在句首,点在它后面；在句尾,点在它前面；在句中逗号要在however前后各用一个）.

普通情况下都是单独放句首，但可以看到很多杂志上都有放句末的，这就像口语一样，不必太讲究，但考试肯定是放句首的
