网友回答
(答案→)children
解析：
【小题1】children 由left Dave a lot of money 可知，David的叔叔没有自己的孩子。
【小题2】set up 指“创办”公司。
【小题3】bought 由前面的found和后面的and moved可知，三个动词是并列的，即A，B and C。
【小题4】towards 由heard someone ing 可知，是“朝着”他的办公司走过来，较表示“到达”的to要好。
【小题5】the 特指他办公室的那部电话。
【小题6】answering 表示“接”电话，习惯上用answer，因be busy doing可知，用answering。
【小题7】who 定语从句，先行词是人someone，且在定语从句中作主语，用who。
【小题8】while 由后面的waited可知，进来时David还在打电话，所以用while。
【小题9】politely 修饰动词waited用副词，在形容词后加ly。
【小题10】was sent因send与I是被动关系，且是到此之前领导派我来的。
