to save money for my marriage ,Father often takes more works than ___is good for his healthAthat B/ Cwhat
答案是C,that后面缺少的应该是一个名词或者相当于一个名词的名词性从句来对应前面的works,只有选C,一个由what引导的名词性从句,what is good for his health指的是对健康有益的工作.如果填that的话,前面的句子是完整了,但后面is good for his health就缺少了主语,如果把is去掉的话就选that,此时（which is）good for his health是定语从句了.
