问题 Chinese public buildings erected under a construction code of the Sung dynasty have withstood earthquakes well because the white cedar used has four times the tensile strength of steel and the timber frame, incorporating many joints and few nails, is flexible.
选项 A、used has four times the tensile strength of steel and the timber frame, incorporating
B、used in them has four times the tensile strength of steel has and the timber frame, incorporating
C、that was used in them has four times the tensile strength steel has, and the timber frame, incorporating
D、that was used has four times as much tensile strength as steel, and the timber frame incorporates
E、that was used has four times the tensile strength steel does, and the timber frame incorporates
答案 A
解析 The sentence presents two reasons the Chinese buildings built under the code described have withstood earthquakes: the white cedar used in them has four times the tensile strength of steel, and the timber frame, which incorporates many joints and few nails, is flexible. The sentence is correct as worded because it clearly specifies these reasons.
A    Correct. As stated above, this version clearly conveys the intended meaning.
B    The construction has four times the tensile strength of steel has is idiomatically incorrect.
The correct construction is has four firms the tensile strength of steel.
C    The comma after has breaks up the sentence in such a way that only the great tensile strength of white cedar is offered as an explanation of the buildings’ ability to withstand earthquakes, rather than both white cedars tensile strength and the timber frame’s flexibility. The statement regarding the timber frame’s flexibility is mentioned simply as a separate fact not falling under the scope of because.
D    This choice presents a similar problem to the one in choice C: the comma after steel breaks up the sentence in such a way that only the great tensile strength of white cedar is offered as an explanation of the buildings’ ability to withstand earthquakes, rather than both white cedar’s tensile strength and the timber frame’s flexibility. Furthermore, the timber frame incorporates many joints and few nails, is flexible is ungrammatical.
E    The construction has four times the tensile strength steel does is incorrect. The correc t construction is has four times the tensile strength of steel. Furthermore, the comma after does creates the same problem that the initial commas in choices C and D cause, suggesting that the only factor allowing the buildings to withstand the earthquakes is the white cedar’s tensile strength. Finally, the sentence ends with the same ungrammatical construction as in choice D: the timber frame incorporates many joints and few nails, is flexible.
The correct answer is A.
