我在 A Course in Basic Scientific English 中遇到这样一个句子： ... a problem is recognized, and as much information as appears to be relevant is collected. 请分析 as much... as。
as much (many) 是表数量的词。在上面的句子里 as much 用作定语, 后一个与之相关联的 as 是关系代词, 在从句中充当主语。有时候也可以充当其他成分。类例:
-
Isabella has as many books as her brother (has). (CGEL) 伊莎贝拉拥有的书像她哥哥那么多。
-
They used as many tools as they found within their reach. 凡能找到的工具,他们全都用上了。
-
I haven't got as much money as I thought. 我手头的钱并不像我原来想象的那么多。
-
We didn't have as many people there as had attended his dinner a few days before. (B. Clinton, My Life) 在我们的集会上没有几天前参加他的晚餐会的人多。(《我的生活》)
-
... there was still tension between us and not as many shared laughs as I was used to on a daily basis with my husband. (Hillary, Living History) ……我们的关系依然紧绷，无法再像往日那样天天分享欢笑。(希拉里，《亲历历史》)
