ZDF106, 108

#106) To help preserve ancient Egyptian monuments threatened by high water table, a Swedish engineering firm has proposed installing pumps, perhaps solar powered, to lower the underground water level and digging trenches around the bases pf stone walls.

在上述的一句话中， 划线部分的 to lower 是不是 installing pumps 的目的？ 而 digging trences 是与 installing pumps 的并列？


#108) With its plan to develop seven and a half acres of shoe land, Cleveland is but one of a large number of communities on the Great Lakes that are looking to their waterfronts to improve the quality of urban life and attract new business.

能帮我理解一下上述的句子吗？ that 是指代什么？ 引导的是定语从句吗？
还有的就是  but one of a large number of communities on the Great Lakes 怎么翻译？

littlegirl

106。yes
108. that引导的定语从句修饰COMMUNITIES。BUT相当于only

gemj

AGREE littlegirl.

最后一问：
but one of a large number of communities on the Great Lakes
五大湖边的众多社区中仅有的一个。
