都是复习中的琐碎问题 话不多说，就上问题啦~以后大家有问题就在这里讨论吧~
http://forum.chasedream.com/thread-700719-1-1.html (附上OG13 12对照)
OG13 部分问题
1、 T1 fail in/ fail to 的区别， 我查了一下fail in 有不足、缺乏；失败的意思， fail to 则是未能做某事 。 Laurie的问题是，在前者做“失败”意义的时候，和fail to 的“未能”有很大的差别嘛？ fail in doing / fail to do 是这样的IDIOM对吗？
2、T7
The intricate structure of the compound insect eye, with its hundreds of miniature eyes called ommatidia, helps explain why scientists have assumed that it evolved independently of the vertebrate eye. 我的问题是关于有些头疼的with，这里的with结构是修饰insect eye做状语成分？为什么OG的解释里说，如果用HAVING的话则逻辑意思就变成了the intricate structure "have"hundreds of miniature eyes. 而用with结构则可以避免这个问题，its就直接指代insect eye了？
3、 T8 In late 1997, the chambers inside the pyramid of the Pharaoh Menkaure at Giza were closed to visitors for cleaning and repair because moisture exhaled by tourists had raised the humidity within them to such level that salt from the stone was crystallizing and fungus was growing on the walls. 在这个正确句子中，为什么them此处指代chambers没有指代歧义。而C选项OG却以them为指代歧义排除呢？
4、T12
Carnivorous mammals can endure what would otherwise be lethal level of body heat because they have a heat-exchange network that keeps the brain from getting too hot. 其实只是想问otherwise在句子中的意思是什么？ 5、T20
Retail sales rose 0.8 of 1 percent in August, intensifying expectations that personal spending in the July-September quarter would more than double the 1.4 percent growth rate in personal spending for the previous quarter. 想知道DOUBLE在这个句子里的词性是? DOUBLE不是可以直接用作动词吗？
另外就是这个题的ADE三个错误选项中都使用了代词 THAT OF ，OG没有解释，我的理解是THAT OF 指代的是前面的personal spending所以和未划线部分的personal spending重复了。这样的理解对吗？

梦之队那里无缘无故的被审核了，很不爽....
以后在这里继续吧....

6、T35
B选项earning them at a time that aviation was still so newu for many of the planes she flew to be
这个错误选项OG上的解释我就不重复了。但是OG没有指出引导词That，我想问time可以作为THAT的先行词嘛？
7. T40
关于C选项 year only if non-OPEC nations,which includes Norway,Mexico,and Russia,would be trimmed
OG解释中说would be 多余
我的理解是only if 引导真实条件句，所以加动词原形就可以了，这样理解对吗 ？
8.T43
1)关于C选项OG解释的疑惑：
C选项BUT Laos with a population of only four million people, many of them are members...
OG的解释说，them is unclear 为什么这里说unclear呢？（千行说，manhattan提到过possessive noun is poor antecedent!）不过还是不大明白~
2)Laos has a land area comparable to that of Great Britain but a population of only four million people, many of whom are members of hill tribes ensconced in the virtually inaccessible mountain valleys of the north.
另外正确选项中，whom是引导定语从句嘛？（千行说的是，独立主格...有点不理解）

9 T132
Although appearing less appetizing than most of theirround and red supermarket cousins, heirloomtomatoes, grown from seeds saved during theprevious year—thev are often green and striped, orhave plenty of bumps and bruises—heirlooms aremore flavorful and thus in increasing demand.
(A) Although appearing less appetizing than most oftheir round and red supermarket cousins,heirloom tomatoes, grown from seeds savedduring the previous year
(B) Although heirloom tomatoes, grown from seeds saved during the previous year, appear lessappetizing than most of their round and redsupermarket cousins
(C) Although they appear less appetizing than mostof their round and red supermarket cousins,heirloom tomatoes, grown from seeds savedduring the previous year
(D) Grown from s e e d s saved during the previousyear, heirloom tomatoes appear less appetizingthan most of their round and red supermarketcousins
(E) Heirloom tomatoes, grown from seeds savedduring the previous year, although they appearless appetizing than most of their round and redsupermarket cousins
这个题我对正确答案没有异议~ 我的疑问在于，关于D选项OG的解释是“Beginning the sentence with the explanatory clause grownfrom seeds... gives it too much importance. It could be construed as the reason why heirloom tomatoes appear less appetizing, which is contrary to the truth. The sentence is also ungrammatical.”
如果Grown...放在句首和Grown...用两个逗号隔开，尽管都是修饰语，但是放在句首的时候更被强调。 可以这么理解吗？

10. T 134
Recently implemented “shift-work equation” based on studies of the human sleep cycle have reduced sickness, sleeping on the job, and fatigue among shift workers while raising production efficiency in various industries. 【OG的解释】Correct. The use of and in this sentenceunites the three parallel elements; the phrasewhile raising provides a clear contrast withhave reduced.
搜索了一些正确句子，还看到了RON关于WHILE用法的解释（表同时性；表对比）
但是只有表同时性的时候WHILE后才是V-ing形式，这里如果是表对比，应当接完整的句子才对...甚是疑惑
（已解决~多谢小默提供链接：http://www.collinsdictionary.com/dictionary/english/while?showCookiePolicy=true）
关于WHILE和Whereas的帖子（比较清楚了）：http://forum.chasedream.com/forum.php?mod=viewthread&tid=770110&highlight=While
引用内容：
1)意思是“当…时”，放句首或句中
2) 意思是“转折对比contrast”时，多放在句中，也可以放在句首。while表示对比概念的时候，两个事物要是同时发生（但是while本身并没有at the same time的意思，所以while at the same time是可以prep 1-96）
3)意思是“虽然、尽管”（让步）时，多放在句首。(=although)
4)表示条件,意为"只要",其意思和用法相当于as long as。while可位于句首,也可位于句中。
While放在句中时要特别注意，像OG12-131的A选项，ETS说while 放在中间表示“同时发生”的意思大于对比的意思。
