　　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 ------- of trees in East Africa has caused the number of native antelopes to ------- sharply because they can live only where the forest is most dense.

　　(A) planting . . decline

　　(B) destruction . . grow

　　(C) felling . . decrease

　　(D) abundance . . dip

　　(E) protection . . drop

　　The correct answer is C

　　Explanation

　　This sentence asks you to recognize a cause and effect relationship: a decreasing number of trees causes antelope populations to decrease. The only option in which both terms have a logical cause and effect relationship is “felling . . decrease.”

　　下面是一道和SAT官方每日一题相似的题目，供大家练习：

　　Dahntay’s ------- over winning the prestigious prize was ------- only by the fact that his father was unable to attend the ceremony.

　　(A) incredulity . . misconstrued

　　(B) ebullience . . tempered

　　(C) bashfulness . . extended

　　(D) satisfaction . . confirmed

　　(E) relief . . conveyed

　　The correct answer is B

　　Explanation

　　This sentence contrasts something positive (winning a “prestigious prize”) with something negative (the father’s absence), so it makes sense that the missing terms reflect Dahntay’s conflicted emotions. His joy, or “ebullience,” might certainly be curbed, or “tempered,” by the fact that his father could not be present for the special occasion.
