为什么要选B?怎么分析
2.He is very busy ___ his papers.He is far too busy ___ callers.
a.writing; to receive b.wrtiting; receiving
为什么选A?far too busy 是太忙的意思,后面不跟doing
答案
it is no use + that从句 或者+doing(动名词形式) b 选项就是一个动名词形式
be busy doing sth 后面的空你理解错误了,应该理解为太忙而不能见访问者,所以应该考虑的是too...to do ...结构（太...而不能...） 而不是考虑far too busy doing 结构
