[单选] After________you have told me I think you should see a doctor

题目：[单选] After________you have told me I think you should see a doctor
A . that
B . what
C . which
D . if

正确答案：B
解析：
考查从句。介词后的宾语从句，如果以连接代词为首，并且该代词在从句中起宾语作用，通常不用that或if。What指所做的事=the thing which，which指某一事物。指代“所说的话”，应用what。选项B是正确的。【句子大意】听了你告诉我的情况，我认为你应该去看医生。
