　　1、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.

　　Exotics and indigenous weeds include some of the most ------- species: their visual impact often eclipses that of nearby plants.

　　(A) lethal

　　(B) diffuse

　　(D) striking

　　(E) resilient

　　正确答案：D

　　Explanation

　　A “striking,” or showy, weed could indeed be said to “eclipse,” or overshadow, other plants that have more typical appearances.

　　2、　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.

　　Demographers and anthropologists have corrected the notion that European explorers in North America entered a ------- territory by showing that the land in some areas was already as densely ------- as parts of Europe.

　　(A) fertile . . settled

　　(B) colossal . . wooded

　　(D) valuable . . exploited

　　(E) hostile . . concentrated

　　正确答案：C

　　Explanation

　　Only “desolate...populated” presents the contrast required by the sentence. The words “corrected the notion” signal that the first word in the correct answer must contrast with the second word because that second word corrects the mistaken notion.

　　3、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.

　　Barbara McClintock’s systematic examination of corn demonstrated the transposition of genes, a finding that overturned entrenched beliefs and proved that ------- study may produce brilliant insights and ------- change.

　　(A) haphazard . . radical

　　(B) inherent . . controversial

　　(D) methodical . . revolutionary

　　(E) derivative . . gradual

　　正确答案：D

　　Explanation

　　Only “methodical study”

　　” and “revolutionary change” match the ideas of “systematic examination” and “overturned entrenched beliefs.”

　　4、　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.

　　To believe that social reforms can ------- evil altogether is to forget that evil is a protean creature, forever assuming a new ------- when deprived of an old one.

　　(A) rejuvenate . . allegiance

　　(B) eradicate . . shape

　　(D) sustain . . episode

　　(E) dissolve . . abstraction

　　正确答案：B

　　Explanation

　　The phrase “is to forget” implies that the belief described in the first part of the sentence is misguided or na瘀攀. It makes sense to argue that the assumption that reforms can “eradicate,” or eliminate, all societal evils is overly idealistic because evil is “protean,” or capable of taking on a new “shape.”

　　5、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 scientist ascribed the ------- of the park’s remaining trees to the ------- of the same termite species that had damaged homes throughout the city.

　　(A) decimation . . prevalence

　　(B) survival . . presence

　　(D) reduction . . disappearance

　　(E) study . . hatching

　　正确答案：A

　　Explanation

　　Choice (A) is correct. It is logical to connect the “decimation,” or harm done to, a park’s trees to the “prevalence,” or dominance, of a harmful species of termites.
