请告知therefore 与however 有什么区别
解题思路： 结合语境辨析。
解题过程：
therefore,
就是因此的意思 后面要紧跟一个句子 后面没有逗号，前后句子意思相关联。却不是因果关系。
I have never been to that city; thereby I don't know much about it.
我从未去过那座城市, 因此对它不怎么熟悉。
therefore: 因为某种原因或结果，所以造成。。。后果。
He was ill, and therefore could not come.
他病了, 所以未能来。
however的用法
however用法详解
一、考点描述however是英语中一个十分重要的考点，近几年来每年的各省考题均有所涉及。请看两道典型真题：
1. You should try to get a good night’s sleep _____ much work you have to do.
A. however B. no matter C. although D. whatever
【分析】答案选A。however作连接副词时，与no matter how相当，后接形容词或副词，意为“无论……”“不管……”。句意是：不管你有多少工作要做，你都应该好好休息一个晚上。
2. He tried his best to solve the problem, _____ difficult it was.
A. however B. no matter C. whatever D. although
【分析】答案选A。因difficult是形容词，修饰形容词要用连接副词however(无论如何，不管多么)，引导一个让步状语从句。
最终答案：略
