只是里面的一道题我有点想不明白
4：Ev en development in architecture has been the result of major technological
changes.Materials and methods of construction are integral parts of the design of architecture
structures.In earlier times it was necessary to design structural systems suitable for the
materials that were available,such as wood,stone,brick.Today technology has progressed to
the point where it is possible to invent new building materials to suit the type of structure
desired.Enormous changes in materials and techniques of construction within the last few
generations have made it possible to enclose space with much greater ease and speed and with
a minimum of material.Progress in this area can be measured by the difference in weight
between buildings built now and those of comparable size built one hundred ago.
7 .In paragraph 4,what does the author imply about modern buildings?
○They occupy much less space than buildings constructed one hundred years ago.
○They are not very different from the building of a few generations ago.
○The weigh less in relation to their size than buildings constructed one hundred years
ago.
○They take a long time to build as a result of their complex construction methods.
为什么选b啊 我怎么觉得是c呢?

C选项在句子“Progress in this area can be measured by the difference in weight
between buildings built now and those of comparable size built one hundred ago.
”里明确的说了,所以不算是“imply”暗示!
同理A也明说了.
D与原文相悖.
B没有明说,也找不到相悖的地方
所以B选项正确
