关系词
5-9：however可做连接性副词及连接副词
however亦有两种词性，一为连接性副词，译成“然而”；一为连接副词，译成“无论如何”，用法如下：
1.连接性副词
由于在本书第二章中，我们已叙述其用法，因此在此我仅举例让同学复习一下。
例：he is nice;however,i don't like him.
=he is nice;however,i don't like him.
=he is nice;i,however,don't like him.
（他人很好，然而我却不喜欢他。）
2.连接副词
此时however等于no matter how。
使用however造句时，注意下列步骤：
（1）先将however转换为no matter how；
（2）由于how为副词，可修饰形容词或副词，故预先造一个含有形容词或副词的句子，以便稍后由how修饰；
例：he is nice.
he works hard.
（3）再将上例句子置于no matter how之后，即成：
no matter how he is nice...
no matter how he works hard...
（4）最后将句中的形容词或副词移位在how之后，形成副词从句，再接主句，即完成整个句子。
no matter how nice he is,i don't like him.
=however nice he is,i don't like him.
（不论他有多好，我都不喜欢他。）
no matter how hard he works,i don't respect him.
=however hard he works,i don't respect him.
（不论他工作有多努力，我都不会尊敬他。）
