问题 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.
选项 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
答案 D
解析 A、B、C中比较对象不对应，因为large plants应该对应smallmills。D、E之间的差异在于D用remain而E用remained的区别，D中remain表明它与to put并列，在它之前省略了to；E中remained表明它与have been able to并列，在它之前省略了have。从句意上分析D正确，表达了句意：既能够把资本投入新科技又能保证经济上的可行性。
