74. (28503-!-item-!-188;#058&003635) Paleontologist Stephen Jay Gould has argued that many biological traits are not the products of natural selection, favored due to their enhancement of reproduction or survival, but that they are simply random by-products of other evolutionary developments. (A) due to their enhancement of reproduction or survival, but that they are (B) due to the reproduction or survival they enhance, but they are (C) because they enhance reproduction or survival, but (D) because they enhance reproduction or survival, but are (E) because of enhancing reproduction or survival, but are 答案选D。 我选的是C。 答案说:(C) but可能作为介词,产生because they enhance reproduction or survival, but simply random by-products的歧意 (D) 正确,but are表明了but在这里只能作为连词,构成be not… but (be)…的平行结构 我觉得not the products of natural selection。。。不是正好和but simply random by-products of other evolutionary developments对称吗? |
