题目错了 条件二是S的平方

A，不能使某人/某物能够被如何，be able/enable to be done是错的。I'm currently unable to be hired by the XX Corporation, because my visa application is still pending.这个句子是可以的，因为可以说我没有能力（使自己）被雇佣。
B，it was possible for the secrets to be unraveled，逻辑错误，秘密不能发起任何主观的动作，不能to be unraveled。应该是t is possible for scientists to unravel the secrets。
it was adj for sb/sth to do sth也表示某人/某物具备一种能力去做某事；通常不说by the study，是by studying
C，果蝇使得科学家能够，错误
C/D，By studying the fruit fly逻辑上是scientists发起的动作，应该离scientists越近越好。

economy is balanced between moderate growth and low inflation，between做介词，接名词构成介宾结构做状语，修饰be balanced，怎样平衡？在适度的增长和低通胀之间是平衡的。

D，view the economy to be balanced between that of moderate growth and low inflation, that of指代the economy of，错误。view the economy to be balanced between moderate growth and low inflation，认为经济处于适度的增长和低通胀之间

没看完选项觉得c特别好直接选了。。实际上c也是病人自己的选择 跟本题医生怎么做是道德的无关

E，was designed and now lined，lined继承前面的谓语动词was，时态错误，应该是was designed and now is lined，比较句里谓语动词是否能省略也经常出现这种问题。

很多和别人比较的情况是错误选项，不代表所有的比较都是错误的！比较的前提是这个比较有意义，要思考这个比较能带来什么信息。A选项的比较说明该大学的fund业绩平平，不就正好说明了他们不努力吗？

a modifier must be either blocked off by commas or not blocked off by commas. you can't block off a modifier with a comma on one side but not on the other.再次mark一下，be sensitive to this kind of problem。
A man from Tornio, Finland, who has developed several innovative cell-phone applications will be speaking at today's meeting.这个句子是对的，因为城市+国家天然地需要两个逗号，who前面事实上与a man之间是没有逗号的，所以后面也不需要逗号。

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

just as A do B, so C do D是一个习惯表达

C选项：代词its是赘余的。只要说在“公司在支付医生和医院费用方面落后”即可以表示选项所呈现的语意了，而不必说“公司在公司支付医生和医院的费用方面落后”。

D选项：如果用ing短语 then proving unable to handle the increase in business，则此时的but只能是介词而不是连词了（连词身后肯定是连接句子，只有介词身后才能用名词短语）。当but是介词是，它的意思是“除了...”。在本选项中，the health care company became one of the largest health care providers in the metropolitan area和it proved unable to handle the increase in business之间应是“转折”关系，而非“除了”关系。

a pair of integers 只有两个数...在脑补啥呢

B，a moderate alcohol consumption, particularly red wine，结构上red wine做同位语，等于及进一步解释说明名词或句子，先行名词是alcohol consumption，红酒不等于酒精消费，应改为particularly the consumption of red wine，或particularly of red wine

proved" can also be an active-voice verb, especially in reference to descriptive qualities.
e.g.
John, who had always bragged the most about his fighting abilities, proved to be the most cowardly person in the group when actual threats arose.
or
my efforts proved insufficient, and i returned home without winning the prize.

不同的质因子的乘积小于本身的根（

A选项：为什么划线部分的代词it应该同未划线部分出现的its指代对象相同，即，the company？ 不是只要可以找到任一合理的指代对象就可以的么? 为什么不可以说是指代profits...

啊啊啊，错了八百遍to do和doing的题。错选B，两个错误，1，began to do强调在某一个时间点后，这里是after report之后。begin doing只是从第三方角度说开始了个什么事。所以本题begin to do更加
2. red wine作为同位语与前边的alcohol同等地位，前边说的是consumption，但是red wine不是consumption！！！

D选项：本选项中的介词短语with a five percent increase是状语（用逗号和主句隔开的介词短语通常都是状语）。顾名思义，状语是用来修饰动词的特性或特征的。在逻辑上，“增长了5%”描述的是profit的特点，而不是be evident的特征，由于profits是名词，所以“增长了5%”必须做profits的定语。

making provision for the removal of the government of the United States to the new federal city, Washington, D.C 为什么不能做后一句establish 的伴随状语

Because of a law passed in 1933 making……，making跳跃了passed in 1933修饰law，因为passed在这里也是定语，而不是谓语动词，所以跳过它去修饰先行词是可以的。
