21题:
原文:These formulas operate on extensive databases of numbers
that define the objects in the pictures as they exist in mathematical space.
问:21. The word "they" in line 9 refers to
(A) formulas
(B) databases

文中的they存在于数学空间,也就是应该是一个数学概念,因此我选择C:numbers

35. Why does the author contrast English and French settlers with Scandinavian settlers in lines 14-18 ?
(A) To suggest that they learned at least some hunting skills from each other
(B) To illustrate that it is hard to decide who established the earliest North American hunting techniques
(C) To explain why the Scandinavians were able to adopt Native American hunting techniques more easily
(D) To show how Native Americans might have acquired steel knives and firearms
我的答案是C,但是网上答案是A
显然,文中说因为在英国和法国hunting是皇家什么什么的,暗示这些平民出生的english and french settlers不懂,因此不能从native americans那里学到什么。但是scandinavian settlers就不一样了,他们对hunting是熟悉的,因此是要表达C:为什么scandinavians更加能够从native american那里借鉴hunting的技巧
这个比较肯定
41 What does the author imply about horse-drawn coaches at the turn of the twentieth century?
(A) They were not available within cities.
(B) They did not provide as good service as the railroads.
(C) They were more popular than bicycles.
(D) They were strong competitors of trams and trolleys.
我的答案是B,但是网上答案是A
文中不是说了:The steam railroad offered the best,
the most reliable and the fastest means of transport. Electric railways (trams and trolleys) provided reasonable intra-urban and short-distance intercity travel They also offered some longer routes, but only in certain parts of the country. Horse-drawn coaches were neither a competitive nor a comfortable alternative given the deplorable slate of the nation's highways;
显然马车提供的服务不如railroad丫,为什么是a?
不是特别确定,欢迎讨论
