accompany
1.accompany是比较正式的词，在口语里通常不用它而用see，如I'll see you to the door和May I see you home?
2.accompany是及物动词，所以可以说I shall accompany him，不可说I shall accompany with him。
3.可以说I shall accompany him to Shanghai和I shall accompany him to the station。不可在宾语后面接不定式，如不可说I shall accompany him to visit Shanghai和I shall accompany him to go to the station。
4.accompanied用作被动语态，除了作combined解以外，现在后面接by，不接with，如The laughter was accompanied with tears和He was accompanied by his wife。当然可以说The singer was accompanied with a flute，但这里的with跟write with a pen, cut with a knife等表达方式里的with相同，是“又当别论”的。
