  • what,引导主语从句,that 在主语从句中不做任何成分 而此句中__we will do is to leave a note to tell Mum we will be back late __we will do 做的是is to leave a note to tell Mum we will be back late 的主语 而 __we will do 从句中do缺少的是宾语 所以what既做主语从句中do的宾语又做is to leave a note to tell Mum we will be back late 的主语 所以用what.此题考查的是名词性从句中的主语从句的连接词的选择问题.不会的可以再问 .
