问题 The use of gravity waves, which do not interact with matter in the way electromagnetic waves do. hopefully will enable astronomers to study the actual formation of black holes and neutron stars.
选项 A、in the way electromagnetic waves do, hopefully will enable
B、in the way electromagnetic waves do, will, it is hoped, enable
C、like electromagnetic waves, hopefully will enable
D、like electromagnetic waves, would enable, hopefully
E、such as electromagnetic waves do, will, it is hoped, enable
答案 B
解析 While the use of hopefully, as used in the sentence as written, to mean I hope that or let’s hope that, is well established, this use is considered to be informal. For this reason, it is generally avoided in writing.
When it is used in this way in writing, however, it must be used at the beginning of a sentence or at the beginning of an independent clause, and be set off by the use of commas. In any case, the use of hopefully in this sentence is incorrect: in a technical sense, it implies that the enabling of the astronomers will be hopeful.
A    The use of hopefully here is incorrect, for the reasons given above.
B    Correct. The use of it is hoped (as opposed to hopefully) here properly conveys the intended meaning of the sentence. Furthermore, the use of in the way appropriately conveys, unlike the answer choices using like or such as, that what is being compared is the interaction, or lack thereof, of gravity waves, on one hand, and electromagnetic waves, on the other, with matter.
C    The use of like incorrectly implies that electromagnetic waves are a type of
matter. Furthermore, the use of hopefully is incorrect, for the reasons given above.
D    The use of like incorrectly implies that electromagnetic waves are a type of matter. Furthermore, the use of hopefully is incorrect, for the reasons given above.
E    The use of such as is inappropriate here: first, such as must be followed by a noun, or list of nouns, rather than a noun followed by a verb, as in electromagnetic waves do; second, the use of like incorrectly implies that electromagnetic waves are a type of matter.
The correct answer is B.
