老托精选阅读100篇之Passage 6中的两个问题，此问答他的回答如下：!
为什么在from（红色）之前要加个used?个人感觉直接用from已经形成“alkalis来自于玻璃制造时的远古遗物”,参照后后面蓝色的from.原文第一段：Potash is one of the two alkalis that were used fromremote antiquity in the making of glass,and from the early Middle Agesin the making of soap.为什么不选A?（马老师给的答案是D,我始终想不通.）因为文章最后一句已经明确指出南部软木资源是匮乏的.—the softwoods in the South proved to be poor sources of the substance.10.According to paragraph 5,the softwoods in the South posed which ofthe following problems for southern settles?(A) The softwoods were not very plentiful.(B) The softwoods could not be used to build houses.(C) The softwoods were not very marketable.(D) The softwoods were not very useful for making potash. 郁美琳儿 1年前他留下的回答 已收到1个回答

问题一：断句应在used和from之间.use是谓语动词,不能去掉；而from是介词,是和之后的时间名词连用的,即from remote antiquity和from the early Middle Ages.若把这两个时间短语去掉,句子也是对的：Potash is one of the two alkalis that were used in the making of glass, and in the making of soap.若把used去掉,句子没有谓语,是错的.问题二：the softwoods in the South proved to be poor sources of the substance.这句话的意思是：softwoods不是生产potash的好的来源,故D选项正确.注意：1. the substance指的是potash；2. 辨析：resource是“资源”,source是“来源” "The resource of the softwoods is poor"才是"The softwoods were not very plentiful"的意思,A选项与原句意思相差甚远. 查看原帖
