However这个词是大家在写作文的时候最常见的转折词，但是在教学中却发现很多同学however的用法简直是千奇百怪。However做转折通常有三种用法
1.放在句首
Your speech is so convincing. However, my father doesn't buy it.
2.放在句中，当插入语 (放在主语与谓语之间，建议使用这个形式)
Your speech is so convincing. My father, however, doesn't buy it.
3.放在句尾
Your speech is so convincing. My father doesn't buy it, however.
4.注意：但是绝对不能和but对换，but是连词，可以连接句子，而however 是副词，可做插入语。（有关插入语的内容请参考链接 ）
Your speech is so convincing，but my father doesn't buy it.
Your speech is so convincing，however my father doesn't buy it. 这句就是错的
Your speech is so convincing，however， my father doesn't buy it. 有些同学认为写成插入语的形式就对了，但是这句话是错的。
其实大家可以发现无论however放前，放中还是放后都是和前一句的转折。
我们知道although与though是不与but连用的，但although与though可以同yet, still, nevertheless, nonetheless 等连接副词（当然yet还可以是连词）连用。
那么although 或though 可以同however 连用吗？
有些老师会说这两个词是不能连用的，但是实际是可以的。应该指出，语义上同but差不多的however或nevertheless等却不是连词而是副词，因此，它可以放在句首或句中，后面可以有停顿，书面上可以前后加逗号，而且可以与although/though相对连用。
用了although/though就不能用连词but，但是可以用副词however。
由于however是副词，这就决定了使用时的一些规则：
（1）如果前面用了although/though从句，主从句之间用逗号分开，however可以就在逗号后面，再加逗号，然后是主句；或者however可以插在主句当中，前后逗号。
例如：
Although this month seemed to be a very quiet month, however, there were a number of activities that had far-reaching consequences. 或
Although this month seemed to be a very quiet month, there were, however, a number of activities that had far-reaching consequences.
（2）如果前面不用although/though，原来的原因从句就变成了独立句，此时它同后一句之间要用分号（；）隔开。后一句的however，也是既可以放在句首，后加逗号，也可以插在句中，前后逗号。
例如：
This month seemed to be a very quiet month; however, there were a number of activities that had far-reaching consequences. 或
This month seemed to be a very quiet month; there were, however, a number of activities that had far-reaching consequences.
（3）如果干脆不用however而用but，则两个句子成了一个并列句的两个分句，彼此之间不用分号隔开，而用逗号（但是用分号也可以）：
This month seemed to be a very quiet month, but there were a number of activities that had far-reaching consequences.
以上的例句表明although和though是可以同however连用的，注意其中的标点符号。
