　　SAT官方每日一题之阅读---完成句子：

　　Critical Reading > Sentence Completions

　　Choose the word or set of words that, when inserted in the sentence, best fits the meaning of the sentence as a whole.

　　The editor denied any knowledge of the reporter’s alleged unethical interview techniques, claiming he had been ------- her finished work but not of her journalistic practices.

　　(A) cognizant of

　　(B) wary of

　　(C) acknowledged by

　　(D) bemused by

　　(E) vindicated by

　　The correct answer is A

　　Explanation

　　To be “cognizant of” something is to be informed about or aware of it. The sentence indicates that the reporter’s interview techniques were allegedly unethical — that is, the reporter was accused of using techniques that do not conform to approved standards. If the editor was unaware of the reporter’s journalistic practices, he could plausibly deny any knowledge of — and responsibility for — her techniques, whether ethical or unethical. Therefore, it makes sense to suggest that the editor would claim that he was cognizant of only the reporter’s finished work and not her journalistic practices.

　　下面是一道和SAT官方每日一题相似的题目，供大家练习：

　　Their conversation was unsettling, for the gravity of their topic contrasted so oddly with the------- of their tone.

　　(A) uniqueness

　　(B) rapidity

　　(C) lightness

　　(D) precision

　　(E) reverence

　　The correct answer is C

　　Explanation

　　Only “lightness” fits the logic of the sentence as being contrary to the “gravity” of the topic. Listening to others discuss a grave (or serious) topic in a light-hearted tone would be unsettling and confusing.
