问题 A new satellite sweeping over the poles at altitudes of up to 32,000 miles is called POLAR, giving scientists their best look yet at the magnetosphere, the region of space under the invisible influence of Earth’s magnetic field.
选项 A、A new satellite sweeping over the poles at altitudes of up to 32,000 miles is called POLAR, giving scientists their best look yet at the magnetosphere, the region of space under the invisible influence of Earth’s magnetic field.
B、A new satellite called POLAR that is giving scientists their best look yet at the magnetosphere, the region of space under the invisible influence of Earth’s magnetic field, sweeping over the poles at altitudes of up to 32,000 miles.
C、Scientists are getting their best look yet at the magnetosphere, the region of space under the invisible influence of Earth’s magnetic field, from a new satellite sweeping over the poles at altitudes of up to 32,000 miles called POLAR.
D、Sweeping over the poles at altitudes of up to 32,000 miles, a new satellite called POLAR is giving scientists their best look yet at the magnetosphere, the region of space under the invisible influence of Earth’s magnetic field.
E、Sweeping over the poles at altitudes of up to 32,000 miles, scientists’ best look yet at the magnetosphere, the region of space under the invisible influence of Earth’s magnetic field, is coming from a new satellite called POLAR.
答案D
解析 Logical predication; Grammatical construction
The point of the sentence is that a new satellite is giving scientists their best look yet at the magnetosphere. As the sentence is written, the participial phrase giving scientists ... magnetosphere illogically modifies the preceding clause A new... is called POLAR, suggesting illogically that the naming of the satellite is what provides scientists with a look at the magnetosphere. The sentence can be constructed more clearly with satellite as the subject of the main clause and is giving as its verb.
A The participial phrase giving scientists ... magnetosphere illogically modifies the whole preceding clause, rather than satellite.
B The subject satellite has no corresponding verb that would create an independent clause; the word that introduces a subordinate clause, and the overall result is merely a sentence fragment.
C The modifier called POLAR is awkwardly placed too far away from the word satellite, which it is intended to modify; in its current incorrect position, it appears to modify altitudes.
D Correct. The sentence is constructed clearly with satellite and is giving as the subject and verb of the main clause, and the modifiers are placed appropriately near the words they are meant to modify.
E Sweeping incorrectly modifies look, and the main subject look is awkwardly paired with the verb is comingfrom.
The correct answer is D.
