标题: 问一个很弱很弱的问题。。。。。。。。。。。。。 [打印本页] 作者: fannybeibei 时间: 2010-7-16 20:02 标题: 问一个很弱很弱的问题。。。。。。。。。。。。。 gwd-1-41 Leaching, the recovery of copper from the drainage water of mines, as a method of the extraction of minerals, it was well established as early as the eighteenth century, but until about 25 years ago miners did not realize that bacteria take an active part in the process. A. as a method of the extraction of minerals, it was well established B. as a method of the extraction of minerals well established C. was a well-established method of mineral extraction D. was a well-established method of extracting mineral that was E. had been a method of mineral extraction, well established
这道题，答案是C，说Dthat was 多余，我就是不明白怎么多余了，没有that was来引导时间状语，as early as又能和谁平行呀？
我觉得有了D的that was ，我们才可以认为that was (a period) as early as the eighteenth century,而不是C中mineral extraction as the eighteenth century
我比较不好啊，请大家帮忙。。。。。。。。。。。。。作者: 姿姿不倦 时间: 2010-7-16 20:07
这里as early as 没有在追求平行这个结构吧？ 它意思不就是 “早至18世纪” 去掉中间插入语 Leaching was a well-established method of mineral extraction as early as the eighteenth century, blahblahblah
继续求教 thanks anyway~~~~~~~~作者: 姿姿不倦 时间: 2010-7-16 20:13
嗯。。我大概懂你的意思了。。可是as early as 就是描述一个时间的短语啊。没有比较对象的吧。就是说早，早到18世纪了。。 比如。。i got up this morning as early as 6 o'clock要是还是理解错了就忽略我吧= = 哈哈我实在是水平不好作者: fannybeibei 时间: 2010-7-16 20:30
