1.在句子中什么时候使用副词?2.在英语中,什么时候用had been doing had done has been doing has done请分别举例,
1.副词一般形容动词或者是形容词,表示发出动作的程度或者是某种状态的程度.如

2.had been doing 表示过去完成进行,如She had been learning dance before she graduated.
had done 表示过去完成,一般句子时态有一般过去式.如：she had attended this party before she met her.
has done表示现在完成,用时经常有一些时间标志词如recently,since,yet,so far等.如He has not finished his homework so far.
has been doing 表示现在完成进行,表示过去发生并且一直在发生的事情对现在甚至将来发生的影响.The building has being built since two years ago
注意：这四种时态也不是固定就那么用的
很多时候要看语境,

had been doing 过去完成进行时
had done 过去完成时
has been doing 现在完成进行时
