In contrast to large steel plants that take iron ore through all the steps needed to produce several different kinds of steel, processing steel scrap into a specialized group of products has enabled small mills to put capital into new technology and remain economically viable.
In contrast to large steel plants that take iron ore through all the steps needed to produce several different kinds of steel, processing steel scrap into a specialized group of products has enabled small mills to put capital into new technology and remain economically viable. (A) processing steel scrap into a specialized group of products has enabled small mills to put capital into new technology and remain (B) processing steel scrap into a specialized group of products has enabled small mills to put capital into new technology, remaining (C) the processing of steel scrap into a specialized group of products has enabled small mills to put capital into new technology, remaining (D) small mills, by processing steel scrap into a specialized group of products, have been able to put capital into new technology and remain (E) small mills, by processing steel scrap into a specialized group of products, have been able to put capital into new technology and remained
根据比较原则,比较对象要可比,直接排除A,B,C D和E的差别就在最后的那个动词,remain的形式 答案是D,其解释为:small mills, by processing steel scrap into a specialized group of products, have been able to put capital into new technology and (have been able to) remain 如此的一个省略,此时remain与put两个动作并列!!
而我纠结的是,以下几种省略错在哪里????? 1: small mills, by processing steel scrap into a specialized group of products, have been able to put capital into new technology and (have)remained 如此的一个省略,此时remained与been able to put两个动作并列!! 2: small mills, by processing steel scrap into a specialized group of products, have been able to put capital into new technology and remain 此时remaine与 have been able to put两个动作并列!!(虽然形式和正确答案的解释是一样的,但是思考的却是根本不一样)
