大全301之迷惑

1.      
Following the nutrition board’s
advice on salt consumption would mean a virtual end of the use of salt in
cooking, an avoidance of obviously salty foods, and reducing the reliance on
processed foods that contain significant amounts of often hidden sodium.

(A) reducing the
reliance on processed foods that contain significant amounts of often hidden
sodium

(B) reducing the
reliance on processed foods containing often hidden but significant amounts of
sodium

(C) a reduction of
the reliance on processed foods, containing as they do often hidden sodium in
significant amounts

(D) a reduced
reliance on the significant amounts of hidden sodium often contained in
processed foods（E）

(E) a reduced
reliance on processed foods that contain significant but often hidden amounts
of sodium

Following the nutrition board’s advice on salt consumption would mean a virtual end of the use of salt in cooking, an avoidance of obviously salty foods, and reducing the reliance on
processed foods that contain significant amounts of often hidden sodium.

解题思路：

首先，句子大结构——主语Following the nutrition board’s advice on salt consumption； 谓语would mean；后面三个并列短语做宾语。而题目中化线部分显然不与a virtual end of the use of salt in cooking, an avoidance of obviously salty foods并列，因此必须从选项中找出与这两个短语形式相近的名词短语。排除A、B。

再看C、D、E， 从逻辑以及语意上排除C、D。

这题的考点：平行结构、修饰成分、以及逻辑表达

注意区别a reduction of the reliance on processed foods与a reduced reliance on processed foods意义的不同

以及体会E中relience on processed foods that contain significant but often hidden amounts of sodiuma这种表达方式比起C、D的简洁、有效、避免歧义

大全中类似的题目有不少，例如：

One view of the economy contends that a large drop in oil prices should evetually lead to lowereing interest rates, as well as lowering fears about inflation, a rally in stocks and bonds, and a weakening of the dollar.

正确选项：B  a lowering of interest rates and of fears about inflation

The economic forces which may affect the new public offering of stock include sudden dowturns in the market, hedging and other investor strategies for preventing losses, lossening the interest rates in Washington, and fearing that the company may still be undercapitalized.

正确选项：E  a lossening of the interst rates in Washington, and a fear that the company may still be undercapitalized.

这题D选项容易误选- a lossening of the interst rates in Washington, and a fear of the still undercapitalized company

GMAT语法中不只要求形式尽量对称工整，最重要的是逻辑意思要正确明了。

不好意思，刚才太仓促，没说清楚

确切的说 ，不是意思不同。

在英文表达上，很少会用a reduction of 加动作性的抽象名词（比如reliance), 而且a reduced relience on比起OF结构更简洁。

其实，我第一次做这题时也错了，所以印象很深。

不过，做多些题目，在横向比较一下，多体会细节的区别，就会有语感啦

想请教大家，为什么C不对？

a reduction of the reliance和a virtual end of the use 的用法不是一样的吗？而且意思对称。

对依赖的减少，对使用的结束，对...的避免。

D和E的去除修饰成分后就是“对...依赖”,从意思上不对称啊？

C最后的分词结构containing as they do often hidden sodium in significant amounts好像也没有大问题啊。修饰processed food。

containing （as they do 如它们contain的那样）often hidden sodium in significant amounts。

as they do 在这里多余吗？

hi, laipiyu

偶来说说, 你看同意否

2楼的已经说了, a reduction of the reliance on processed foods与a reduced reliance on processed foods意义不同

因为a reduction of the reliance 核心词在于reduction,强调的是reduction的过程/动作 而

a reduced reliance 在于reliance,强调 已经减少的reliance,即结果

虽然翻译成中文可能差不多, 但在英文里面的意思还是有差别的

所以这里不能单单看形式层面的平行,更要看逻辑意思

并且从平行的前两个成分来看, a virtual end of the use of salt in cooking, an avoidance of obviously salty foods, 要说对称, reliance作核心词更能匹配end/avoidance

不知道讲清楚了伐

至于你另外一个问题, 我想你把A和C比较一下,自然就有结果了

(A)  infrared radiation, however, is invisible because its
wavelength--0.1 millimeters--is too long to be registered by the eye

(B)   however, the wavelength of infrared radia­tion--0.1
millimeters--is too long to be registered by the eye making it invisible

(C)  infrared radiation, however, is invisible because its
wavelength--0.1 millimeters--is too long for the eye to register it

(D)  however, because the wavelength of infrared radiation is 0.1
millimeters, it is too long for the eye to register and thus invisible

(E)   however, infrared radiation has a wavelength of 0.1 millimeters
that is too long for the eye to register, thus making it invisible
