　　(A) manifest

　　(B) dilatory

　　下面是一道和SAT官方每日一题相似的题目，供大家练习：

　　Ray was ------- gambler who had seldom gone a day without indulging his expensive habit.

　　(A) an inveterate

　　(B) a dubious

　　(C) an occasional

　　(D) a novice

　　(E) an obnoxious

　　The correct answer is A

　　Explanation

　　Choice (A) is correct. If this term were inserted into the sentence, the sentence would read “Ray was an inveterate gambler who had seldom gone a day without indulging in his expensive habit.” The term “inveterate” describes something that is established by a persistent habit. If Ray had “seldom gone a day” without gambling, one could certainly say that gambling was his persistent habit. Therefore, it makes sense to describe Ray as “an inveterate gambler.”
