The teacher told us that the problem was not _____ easy and that we should think _____ over carefully.
A. such, it B. that, it
C. such, 不填 D. that，不填
B
第一空填that，that 用作副词，相当于 so，另外，汉语中说“好好想一想”，通常可以不带宾语，但英语中的think over 是及物动词，如果用它来表示“好好想一想”，应根据上下文的语境让它带上适当的宾语，所以本题应用 think it over，相当于 think the problem over。
