— ________ that I remember what was ________ after he went out.

A. To see to it; to be done

C. To make sure; to do

D. Seeing to; done

A。【解析】考查非谓语。句意：——他为什么要让你把他的指示重复了一次又一次?——为的是努必使我记住他出去后我应该做什么。”第一空为不定式作目的状语，用来回答问句。第二空的主语是what,应用被动，选择to be done，see to it that的意思是“努必使...”、“注意使...”。故选A。

A. from

B. by

C. at

D. for

D。【解析】考查介词。句意：史密斯夫妇因为养育孩子的方式而受到了赞扬。根据固定搭配 praise sb.for sth. 可知答案为D项。因句中的“are praised...”，学生很容易理解为“被...表扬”而误选by。故选D。
