解析：
【小题1】我很感激Mr. Johnson对我的工作的帮助，我要亲自感谢他。考查副词“亲自”： personally。
【小题2】我必须因为没有让你提前知道计划而道歉。考查动词“道歉”：apologize。
【小题3】路边艺人的表演真的很精彩，以至于吸引了所有过路人的注意。考查名词“表演，表现”：performance
【小题4】他渴望在音乐会上欣赏贝多芬的音乐。Look forward to后面接动名词：admiring
【小题5】自信是成功的第一步。这里是做主语的，所以用名词：confidence
【小题6】别担心，问题已经被解决了。这里problem和solve是被动关系，用solved
【小题7】问题在会议上被提出，但是没有人知道怎么回答。从but no one knew how to answer it.可知用一般过去式： arose
