boldface是argument主要的结论，后面的部分是得出这一结论的前提

what充当主语从句中的主语时，主句谓语与从句谓语保持一致
what is difficult to determine is A.
what are difficult to determine are A and B.
what充当主语从句中的宾语时，主句谓语与主句表语/宾语保持一致
what his father left him are a few English books.

没有从those和such指代角度分析的嘛？

有的时候不能主观揣摩作者意图，有的时候又需要
原文的only我都不敢去主观猜测作者的意思是说美国的一定高于29%

the amount of NOUN是单数名词
the amounts of NOUN是复数名词
the number of NOUN是单数名词
the numbers of NOUN是复数名词
by far是目前为止的意思

news of these shots是单数，所以排除AC

1.Rhetorical construction，possibility和could都表达可能，重复了，AB错.
2.代词，it指代不明，不太好，AB不太好
3.idiom，overlook是及物动词，overlooking that the forces中的that不需要，C错.Overlook the fact that...是对的，另外还有despite the fact that...
4.逻辑推理，repeat的对象应该是disaster，而不是forces，ABD错。
补充：这些单词都不能直接接that从句
allow
refuse
let
like
cause
force
condemn
celebrate
dislike
entreat
love
help
overlook
loathe
forgive
take（认为）

1.idiom,not so much....as...ADE错
2.平行，BE前后不平行，BE错

A. and with没有前面的结构与其平行，做的时候错认为“With surface temperatures estimated at minus 230 degrees Fahrenheit”与后面的with平行了
B. 独立主格结构，是正确的
C. and表示“has long been considered as far too cold to support life”和"has 60 square miles of water thought to be frozen from top to bottom"是平行的，但是逻辑上来说"60 square miles of water thought to be frozen from top to bottom"应该是修饰“has long been considered as far too cold to support life”
D. 没有谓语动词
E. 没有谓语动词

平行考点。in the USA 和 in Britain; weighing vs not ready 修饰小猪

这道题有两个标记点：
第一段：Yet the flowers of the Sonoran Desert cacti have evolved to remain open after sunrise, allowing pollination by such diurnal visitors as bees and birds.
第三段：While data suggest that population densities of nectar-feedingbats are also low in tropical areas of southern Mexico, where bats are the exclusive pollinators of many species of columnar cacti
第一段说了，SONORA以前只有蝙蝠传播花粉，后来evolve了。第一段没提到southern，不是出题点。
最后一段说，southern现在还是只有蝙蝠传播花粉，和SONORA不一样，所以这就是两者区别

1.逻辑推理，than平行，the nuclear industry than political oppositiond会产生歧义，是拿这两个在对比，所以应该加is，表示主句之间的对比。BCE错
2.简洁表达，even more serious a deterrent不如an even more serious deterrent读起来明白，而且前者会产生歧义，不仅是一个a deterrent，还可以是其他东西？B错
3.Diction,清晰表达，Furthermore, the sentence would be clearer if it said resulting from，ABC相对更差
4.动词，deterring to the nuclear industry 用法错误，deter是及物动词，应该直接接名词，AE错

However, whereas cactus-flower abundance tends to be high during spring, bat population densities tend to be low except near maternity roosts.
花的数量很多，但是相对bats的密度偏低。->导致了bats无法给所有的花授粉

C The family assuming many of the functions previously performed by schools and churches
assuming错误，对应回文中内容，virtue was to be instilled not only by churches and schools, but by families, where the mother’s role was crucial.。
文章并没有提到family 有过assume这个动作。

reflecting a shift in view = attitudes concerning women’s education that were reflected

Pointing to “An Essay on Woman” (1753) as reflecting a shift in view, Woody also claimed that practical education for females had many advocates before the Revolution.

1.对比，逻辑推理，unlike in britan，或者as there is in britain是平行的，ABCD全错
2.句子结构，ACD的a fact部分表达都不太好，要么冗杂，要么句意错误
3.make it difficult to do...是正确用法，ACD错

这道题也是考对最后一句话的理解。

It may be that males can use scarce carotenoids either for immune defense and detoxification or for attracting females. ---注意是or

females prefer males with brighter carotenoid-based coloration.
