97. The stars, some of them at tremendous in motion just as the planets are, yet being so far away from Earth that their apparent positions in the sky do not change enough for their movement observed during a single human lifetime. (A) The stars, some of them at tremendous speeds, are in motion just as the planets are, yet being (B) Like the planets, the stars are in motion, some of them at tremendous speeds, but they are (C) Although like the planets the stars are in motion, some of them at tremendous speeds, yet (D) As the planets, the stars are in motion, some of them at tremendous speeds, but they are (E) The stars are in motion like the planets, some of which at tremendous speeds are in motion but Answer: B OG解释: B. correct. The conparison is clear and eggective in this sentence; the second clause includes a subject and a verb. 这句的结构应该是这样: the stars are..., but they are....我记得OG里面的题目连词后出现主语除非是新的句子, 不然应该是错的: OG11-39. Scientists have recently discovered what could be the largest and oldest living organism on Earth, a giant fungus that is an interwoven filigree of mushrooms and rootlike tentacles spawned by a single fertilized spore some 10,000 years ago and extending for more than 30 acres in the soil of a Michigan forest. (A) extending (B) extends (C) extended (D) it extended (E) is extending OG解释: it extended in D begins a new clause; 127. Found throughout Central and South America, sloths hang from trees by long rubbery limbs and sleep fifteen hours a day. moving infrequently enough that two species of algae grow on its coat and between its toes. (A) sloths hang from trees by long rubbery limbs and sleep fifteen hours a day, moving infrequently enough (B) sloths hang from trees by long rubbery limbs, they sleep fifteen hours a day, and with such infrequent movements (C) sloths use their long rubbery limbs to hang from trees, sleep fifteen hours a day, and move so infrequently (D) the sloth hangs from trees by its long rubbery
limbs, sleeping fifteen hours a day and
moving so infrequently (E) the sloth hangs from trees by its long rubbery
limbs, sleeps fifteen hours a day, and it moves
infrequently enough D, the best choice, correctly subordinates sleeping and moving to hangs while using the idiomatically correct phrasing so (infrequently) that.... The pronoun its shows clearly that the limbs belong to the sloth, not the trees. Choice A illogically coordinates hang and sleep and, like E, uses the unidiomatic expression infrequently enough that. B creates an awkward and nonparallel series: sloths hang ..., they sleep ..., and with.... C creates a confusing and absurd image with use their... limbs to hang ..., sleep ..., and move .... A, B, and C all mistakenly use the plural sloths, which does not agree , with its coat and... its toes. E wrongly coordinates hangs and sleeps and violates parallelism by inserting it before moves to create a new independent clause. 够了,我想这已经足已说明平行结构中, 连词后不能再出现主语, 不然就create a new independent clause了. 可是OG97却说这样是对的,为什么呢?? |
