　　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.

　　He maintains that ethnic and cultural ------- are generalizations no more related to what an individual is actually like than are the ------- representations of constellations to the actual nature of a star.

　　(A) traditions . . chemical

　　(B) stereotypes . . pictorial

　　(C) details . . figurative

　　(D) heritages . . prophetic

　　(E) specimens . . graphic

　　The correct answer is B

　　Explanation

　　The terms in choice (B) logically complete the sentence’s comparison between ethnic and cultural “generalizations” and certain “representations of constellations.” “Stereotypes” are oversimplified generalizations that do not necessarily describe what a particular person is actually like—just as “pictorial,” or picture-based, representations of constellations cannot accurately describe a star’s “actual nature.”

　　下面是一道和SAT官方每日一题相似的题目，供大家练习：

　　(A) sinuous

　　(B) encumbered

　　(C) colossal

　　(D) prodigious

　　(E) furtive

　　The correct answer is D

　　Explanation

　　The sentence focuses on an ability that is "extraordinary," or very remarkable. It makes sense to suggest that this remarkable ability is just one of the salmon's "many prodigious skills," or only one of the salmon's many remarkable and impressive skills.
