副词性连词 Conjuctive Adverbs
副词性连词,词性是个副词,有连词的含义,也就是说,形式上不具备连接词的功能

- Bob is good. Tom ,however, is bad.
2.放在句首,后面接逗号再接句子
- Therefore, the film is less than perfect.
3.句子A ; 副词性连词 , 句子B
- The pianist was very ill; therefore, the concert was canceled.
At the beginning (followed by a comma):
- However, the experiment was unsuccessful.
After a semicolon (followed by a comma):
- We tried applying several different variables; however, the experiment was unsuccessful.
In the middle (usually surrounded by commas):
- The experiment, however,was unsuccessful.
At the end:

常见问题:混淆 从属连词 和 连接副词
连接副词后要立刻接一个逗号:
- However, the experiment was a failure.
但从属连词后并不会直接接逗号:
- ❌ -Although, the experiment was a failure.-
- Although the experiment was a failure, we decided to try again with new variables.
