小题4:towards
小题5:the
小题6:answering

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 coming 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。
