2. The author lists various animals in line 5 to

A. contrast the feeding habits of different types of mammals

B. describe the process by which mammals came to be defined

C. emphasize the point that every type of mammal feeds its own young

D. explain why a particular feature of mammals is nonelective

原文：All mammals feed their young. Beluga whale mothers, for example, nurse their calves for some twenty months, until they are about to give birth again and their young are able to find their own food. The behavior of feeding of the young is built into the reproductive system. (It is a nonelective part of parental care and the defining feature of a mammal, the most important thing that mammals-- whether marsupials, platypuses, spiny anteaters, or placental mammals -- have in common.)

括号中是我定位的，是选C吗，不确定。谢谢

7. The word "edge" in line 17 is closest in meaning to

A. opportunity

B. advantage

C. purpose

D. rest

原文 ：Animals add it to their reproductive strategies to give them an (edge) in their lifelong quest for descendants.

Edge有优势的意思吗？大家做的选哪个啊？我的答案是B，查字典也没有好处的意思啊？

19. According to the passage, what do woodcut and engraving have in common?

A. Their designs are slightly raised.

B. They achieve contrast through hatching and cross-hatching.

C. They were first used in Europe.

D. They allow multiple copies to be produced from one original.

21. According to the passage, all of the following are true about prints EXCEPT that they

A. can be reproduced on materials other than paper

B. are created from a reversed image

C. show variations between light and dark shades

D. require a printing press

这两道题就不好办了，因为我没找到定位点，所以请作过的人指教， (我怕我把整篇文章摆上大家晕了，所以请好心人帮我看看你们做时，答案是选哪个。)

这篇文章具体是说两种印刷术。它们有什么相同之处。

39. Virginia is mentioned as an example of a state that

A. built roads without tollgates

B. built roads with government money

C. completed 1,500 miles of turnpikes in one year

D. introduced new law restricting road use

原文：Northern states generally relied on private companies to build their toll roads, but Virginia constructed a network at public expense. Such was the road building fever that by 1810 New York alone had some 1,500 miles of turnpikes extending from the Atlantic to Lake Erie.

我选的是C，但答案是B(当然网上的也可能有误)，虽然没有提到一年就建好，但是FEVER也可以表示它建的速度快吧，何况这里也没说它没用政府的钱啊？难道是我定位有误？晕….

44. In lines 13-17, why does the author compare tree roots with growing salt crystals?
A. They both force hard surfaces to crack.
B. They both grow as long as water is available.
C. They both react quickly to a rise in temperature.
D. They both cause salty water to rise from the groundwater table.
原文：Like tree roots breaking up a sidewalk, the growing crystals exert pressure on the rock and eventually pry the rock apart along planes of weakness, such as banding in metamorphic rocks, bedding in sedimentary rocks, or preexisting or incipient fractions, and along boundaries between individual mineral crystals or grains.

这道题是选A吗？不确定，因为以前答案错的太多了。

当然是B!

Virginia所在的句子很清楚的讲了北方的州大部分是靠私人公司建路的，but 但是Virginia却是用公共资金的。government的钱就是大家的钱！偶们上税的呀！

MM，以后发帖请一题一帖，便于大家回复和查询。

另外，上面有两题没有文章内容的，因为我手边也没有文章，无法回复了。见谅！

5，C

7，尽管这套题我没做过，跟据楼主的材料我绝得应该把前面一句也做为判断的理由，因为提目中的代词IT还原后会好做点。带入原文似乎A，B都可,但顷向B，因为谁都有机会生育，不是加个东西就可以改边的。

39，B，public expense与private companies 比，FEVER表热潮

44，A，exert pressure on the the rock and eventually pry the rock apart along planes of weakness可知2者先压石（硬物）后裂石的生长方式类似。
