2. Hurricanes at first begin traveling from eastto west, because that direction is the way the prevailing winds in the tropicsblow, but they then veer off toward higher latitudes, in many caseschanging direction toward the east before dissipating over the colder, morenortherly waters or over land.
(A) Hurricanes at first begin traveling from east to west, because thatdirection is the way the prevailing winds in the tropics blow, but
(B) At first, hurricanes travel from east to west, because that is thedirection of the prevailing winds in the tropics, but
(C) While hurricanes travel from east to west at first, the direction of theprevailing winds blowing in the tropics, and
(D) Because hurricanes at first travel from east to west, since it is thedirection of the prevailing winds in the tropics,
(E) Hurricanes, beginning by traveling from east to west, because this is thedirection of the prevailing winds in the tropics,
正确答案为B,对错误选项中的两处结构产生了疑问,不知道有没有问题,官方解释中也没有提及。 1. C选项,如果改正官方解释中提到的错误变为“ Hurricanes travel from east to west at first, thedirection of the prevailing winds blowing in the tropics, but " 那么其中the direction ofthe prevailing winds blowing in the tropics 在句子中是什么成分呢,插入该短语后句子有问题吗?个人感觉该短语既不是独立主格,也不是同位语(同位语一般都是名词+that从句)。 2. 同样D选项中改正官方解释中提到的错误变为" Hurricanes at first travel from east to west,since it is the direction of the prevailing winds in the tropics, but" 其中半句原因状语从句since it is thedirection of the prevailing winds in the tropics 插在让步状语从句中,这样的结构对吗?不对的话算是什么错误呢?
