40. In metalwork one advantage of adhesive-bonding over spot-welding is that the contact, and hence the bond­ing, is effected continuously over a broad surface instead of a series of regularly spaced points with no bonding in between.

(A)   instead of

(B)   as opposed to

(C)   in contrast with

(D)  rather than at

(E)   as against being at

The corrected sentence must contrast an effect of spot-welding with an effect of adhesive-bonding. To do so logically and grammatically, it must describe the effects in parallel terms. When inserted into the sentence, D produces the parallel construction over a broad surface rather than at a series. Having no word such as over or at indicate location, choices A, B, and C fail to complete the parallel and so illogically draw a contrast between surface and series. In E, as against being is a wordy and unidiomatic way to establish the intended contrast. Choice D is best.

1.rather than is preferable to instead of

2.as opposed to something
used to compare two things and show that they are different from each other
Students discuss ideas, as opposed to just copying from books.

3.rather than is the test point, so it may be better

可是,从og的解释看,只说因为a,b,c后面没有正确的补出介词,所以选d,并没有说rather than从语法或意思的角度优于a,b,c呀

而且从og的解释看根本没说rather than是test point;而且rather than is preferable to instead of 是新东方的说法.确实可行,但我这题并没选错,只是就og解释论og解释.

望进一步讨论.

instead of中of是介词，不能再跟介词了。

rather than中than为连词。
