请看OG128 128. New hardy varieties of rice show promise of producing high yields without the costly requirements of irrigation and application of commercial fertilizer by earlier high-yielding varieties. (A) requirements of irrigation and application of commercial fertilizer by earlier high-yielding varieties (B) requirements by earlier high-yielding varieties of application of commercial fertilizer and irrigation (C) requirements for application of commercial fertilizer and irrigation of earlier high-yielding varieties (D) application of commercial fertilizer and irrigation that was required by earlier high-yielding varieties(E) (E) irrigation and application of commercial fertilizer that were required by earlier high-yielding varieties Choice E, the best answer, clearly and grammatically expresses the idea that two costly procedures, irrigation and the application of... fertilizer, were required by earlier high-yielding varieties of rice. In A, the placement of by earlier... varieties immediately after application of fertilizer suggests that the varieties applied the fertilizer. In B and D, the phrase application of... fertilizer and irrigation is ambiguous in meaning: it cannot be clearly determined whether applying fertilizer and irrigating are a single operation or two distinct operations. In C, only irrigation—not both irrigation and fertilization—is clearly associated with the earlier... varieties of rice. A选项中,N1 of N2 and N3是有歧义的,所以E选项中变成了 N3 and N1 of N2,从而避了歧义!
所以我觉得在讨论的真题中D答案是对的,不会引起歧义!
请NN指点!
