提问:

In three centuries -from 1050 to 1350-several million tons of stone were quarried in France ( for the building of eighty cathedrals, five hundred large churches, and some ) tens of thourands of parish churches. A. for the building of eighty cathedrals, five hundred large churches, and some B. in order that they might build eighty cathedrals, five hundred large churches, and some C. so as they might build eighty cathedrals, five hundred large churches, and some D. so that there could be built eighty cathedrals, five hundred large churches, and E. such that they could build eighty cathedrals, five hundred large churches, and 把句意理解错了,选了D,答案是A。当时想的是一些石头被挖掘了在法国,后面应该是:导致在法国建立了多少教堂。排除BCE是感觉they指代有问题。没选A是不知道原文说的是这些石头用来建立教堂,而且后面有个some,不能理解some tens of throusands of。麻烦老师讲解。

提问:

7.15/寂静:STUVW, 5个人, V和W中间必须隔一个人,求问共有几种组合? 我的想法是这样的A(3,3)*A(2,2)*C(3,1)=36种;思路如下:先把V+C(3,1)+W看成一个整体;可得:A(2,2)*C(3,1)种排法;然后5个人可分成三类,于是A(3,3)。不知道我的想法对不对,请老师解答。感激不尽!
