Your mother has been ________ you so much．You should not ________ her any more．

A.worried; worry

B.worried about; worry

C.worried; worry about

D.worried about; worry about

答案及解析： B

解析：

题意是“你母亲一直那样担心你，你不应该再让她担忧”。主要考查worry的用法。worry是及物动词，意思是“使人担心；担忧”。be worried属系表结构，接介词about，意思是“为某人担心；担忧”。B选项符合句子结构。
