解析：这是一份对别人邀请的回信，作者主要描述了自己接下来一周要做的一些事情，来说明自己不能接受邀请的原因。【小题1】根据前文谓语动词am及汉语提示可知填形容词sorry做表语。【小题2】根据下文名词week，周，及汉语提示可知填形容词busy做定语。【小题3】考察习惯用法，go bike riding，骑自行车，故填riding。【小题4】联系下文breakfast早饭及汉语提示可知填形容词quick做定语。【小题5】联系前文定冠词the及汉语提示可知填名词dentist。【小题6】本句谓语不完整，联系前文be动词am，及汉语提示可知填动词的现在分词exercising，部分动词的现在进行时态可以表示计划打算进行的动作。【小题7】根据汉语提示及语境可知句意为物理学科，故填名词physics。【小题8】根据前文be动词及汉语提示可知填形容词important做表语。【小题9】根据汉语提示可知填介词until。【小题10】考察短语at that moment在那时刻。

谢谢回答！！！
