A说没外包出去的是什么，没说外包出去的怎么样 - 没外包出去的，不一定就是外包出去的反面

examining 需要对结果发出态度，而文中直接就结果指向了接下来的方向

x=12u=4(2y+3),=> Y=3/2(u-1),
X=12u,=> Y/X=u-1/8u,（你看u=3带入x,y.公约为3,=5,公约为6.）
x,y正整数
=>公约不定.
2）
同上理：Y/x=8Z+1/Z 无论z是几,公约都只是1

mark,
clones是复数，所以是可数名词 —— 克隆物。不是克隆这个技术或概念。后面还接了一个their，能比较的对象也应该是一个复数的。ABC the cheetah species是单数，D的homogeneity也是单数。选E

mark 好题 点多 查看笔记

E夹心修饰，dominating可以向前修饰Schoenberg and the twelve-tone system这个并列名词作后置定语，也可以向后Batork founded 作状语

B：两个主语，排除。
C：逗号不能连接两个完整句子。
D：carrying表示伴随修饰，意味着minivan的优点只有伴随着满载七个人的时候才会发生，事实上两个部分是并列关系。
E：and表示两者之间为独立并列关系，事实上and之后的部分都是对minivan和其他车型比较的优点的陈述。

hen you look at these sentences with "and", you need to figure out what should be grouped -- in other words, which ideas are meant to be expressed in parallel structure.

in this sentence, those two ideas are the two facts about the asteroid:
* the asteroid is about 1/2 mile wide.
* if the asteroid strikes earth, blah blah blah xxxxx will happen.

if do, then will do /can do
if did, then would do/could do
if had done, then would have done/could have done

在(A)(B)中，expectation的同位语部分是一个句子，这个句子的核心词是动词double；在(C)(D)(E)中，该同位语部分的核心词为personal spending。其次，我们在题目中还可以发现比较词more than。

B选项：compared to Germany是过去分词短语，应就近修饰名词nuclear power，这在逻辑上是不正确的。真正的对比对象应该是德国和法国。
D选项：the energy前的定冠词the表示这个energy指代前面出现过的energy，即，生产于法国的核能，这句话的意思变成了“在法国，超过33%的能量来自于德国生产的核能”，失去了比较的意义（和选项(C)不同，该选项中energy身后有定语produced in Germany）。

演绎推理

做了100遍了还是错。。。

e选项好坏，把profit和 efficiency 搞反了

babies were born to women over the age of thirty than babies were born to women under it.

But for N, S + should/would/cold/might + V / (have Vpp.) 若不是N, S应该….
= If it were not / (had not been) for N
= Were it not for N / (Had it not been for N)
= Without N（介词只有without可表虚拟语气）
虚拟语气的时态：
时间 从句谓语形式 主句谓语形式
将来 动词过去式(be用were)
should + 动词原形
were to + 动词原形 would / should / might / could + 动词原形
现在 动词过去式(be 用 were) would / should / might / could + 动词原形
过去 had +动词过去分词 would / should / might / could have + 动词过去分词

本题从划线部分开始其实是一个定语从句，先行词为the price。很多考生可能会记得一个说法：“逗号后面不能加that”。这是完全错误的，应该记为：“that不能引导非限制性定语从句”。例如本题，per milligram其实是一个插入语，不影响the drug's maker charges for another product with the same active ingredient作the price的限定性定语从句。

这个参考答案稍有模糊，搬运RON的解释A.ing修饰语修饰逗号后面紧跟的单词，错B.She 在Selma前面，这是不对的。
actually, the way the parallelism is written here, "she" doesn't mean selma.if i say "he wrote the first half, and jim wrote the second half", then the one thing of which you can be absolutely sure is that jim didn't write the first half.
C. .i don't like "was a novelist" either; it seems to imply that selma stopped being a novelist at some point, becoming something else."

本题难度不大，只要知道just as A do B, so C do D是一个习惯表达即可。这里总结一下just as…so…这个习语的用法。实际上，just as A do, so B do平行比较结构的习惯搭配：意思是：就如同A…B…。这里的as是不能用like,whereas的。
下面三种形式无区别，前后都要用句子，不能只用短语。
Just as … , so … Just as you sow, so you will reap
Just as … , as … Just as you sow, as you will reap
Just as … , so too … 主句要部分倒装(so too后是主句) Just as you sow, so too will you reap
本题答案为(C)。
