标题: 请教PREP2-25题！！！！！！

There is a widespread belief in the United States and Western Europe that young people have a smaller commitment to work and a career than their parents and grandparents and that the source of the change lies in the collapse of the "work ethic."

(A) a smaller commitment to work and a career than their parents and grandparents

(B) less of a commitment to work and a career than their parents and grandparents

(D) less of a commitment to work and a career than their parents and grandparents had

(E) a lessening of the commitment to work and a career that their parents and grandparents had

答案是D 为什么补助动词had? 我觉得要补助动词应该补DID呀请高手赐教！

还有 less of a commitment 可以这么用吗？如果可以的话后面应该怎么写？感激！

than their parents and grandprerents had 吗？

以下是引用piggyzhuzhu在2008-6-27 11:29:00的发言：

我印象里好像主句动词为完成时的时候比较才补出have/had 吧？毕竟补出的是助动词这句话里面虽然出现have 但是have不是助动词而是一个实意动词呀所以我觉得应该补出did才合适……个人一点见解

我觉得这里的had 和did都对。。

首先就看你吧have当作一个什么看待了。

I havenn't a sister =I donn't have a sister.

这里明显把have当作了类似Be动词的类型。。

have less of=更加少。。

如果have 作助动词的话后面应该会接实意动词的吧题目里面就是have commitment 所以我还是认为应该补助动词did比较合适

这里had不当助动词来看啊,就是把实意动词再重复说了一遍,加以时态的变化

个人觉得如果不用had,补did也是可以的

同问:less of a commitment 这个用法怎么理解,觉得怪怪的

作者: dingxiang 时间: 2008-8-14 22:57

楼上的

less of 表示程度

具体可以查LDOCE

同意. 好象之前在哪道题里也有过类似的讨论...后来LES前辈这么总结的.

所以这题我选了B. 因为找不到did, 我想既然跟前面的have意思一样, 是不是就可以省略了. 请问, 这样的省略会造成什么样的歧义?

请问a smaller commitment 为什么部可以阿

作者: yezi870514 时间: 2008-8-24 19:33
是有歧义的，一定要加动词

作者: smartsky11 时间: 2009-3-20 13:06
啊

S1. V1. more O1. than S2. V2. V2.只需助动词

= S1. V1. more O1. than O2. O2.常用that/those代替

作者: lcy19812000 时间: 2009-4-12 13:34
S1. be1. more

1. than S2. P.是表语。

再贴一遍题：

25. (25704-!-item-!-188;#058&002607)

(A) a smaller commitment to work and a career than their parents and grandparents

(B) less of a commitment to work and a career than their parents and grandparents

(D) less of a commitment to work and a career than their parents and grandparents had 答案：D

(E) a lessening of the commitment to work and a career that their parents and grandparents had

我觉得这道题在than后面不不出助动词完全没有问题，因为是否补出来是看是否会产生歧义，这里如果要产生另外一种意思的话只能是young people have less of a commitment to work and a career than to their parents and grandparents 。而事实上，没有这个to，所以their parents and grandparents 只能和主语young people 平行。至于D项不加did却加had很诡异啊，哪位NN解释一下这个had表示的是什么意思？

我来说less of, 向前是修饰动词have的，而不是后面的名词。在白勇还是刘振民语法里面提到过的，两本都看了，忘了是哪本说的了，不过肯定是这个解释。这样就是动作的比较，have 和 had（过去时）比较。

大家觉得a career 是和谁平行的呢？是和a commitment吗？

Because natural gas is composed mostly of methane, a simple hydrocarbon, vehicles powered by natural gas emit less of certain pollutants than those burning gasoline or diesel fuel.

为何这句less of的结构里面those burning gasoline or diesel fule后面省去了和emit相对应的did 呢？

作者: zoemiaoer 时间: 2010-9-25 21:11
难道没有人可以解释么？

我觉得比较结构中的比较成分的省略关键是要看比较成分中有哪些部分是完全一致的。
所谓完全一致就是指包括形式、时态、语态、语气等等都要完全相同。如果完全一致就可以省略，如果不完全一致，就要把不完全相同的地方加上去。

在Prep2-25，由于是现在的年轻人have和他们的父母辈比较，因而父母辈是had，所以不能省略，要加上had/did.

在这道题里，比较的是vehicles powered by natural gas 和 vehicles powered by gasoline 两者所emit出来的pollutants, 如果要加的话也只能加do，这从时态、语态、语气上来看和原句的emit都是一样的，因此可以省略do。

不知道这样的规律对不对，我会再找找，到时候贴一些例子上来~~

至于Prep2-25中，加had而非did，我觉得是因为题目中只有加had的选项，也就只能选had的选项了。其实，had 和did应该都可以。

less of a commitment 是名词短语，意思是更少的承诺。
另外比如：less of a problem 是指更小的问题。

作者: DeliciaAn 时间: 2015-6-14 16:05
补充下less of 的意思。
reference: http://www.thefreedictionary.com/less

less of：
to a smaller extent or degree
举例： we see less of John these days; less of a success than I'd hoped.

你可逗吧您在哪儿见过haven't a sister啊？？haven't那是典型完成时做实意动词的助动词，have a commiment这不赤裸裸的实意动词

关于less of: 终于找到曼哈顿里Ron的明确解答---"Less of a/an ___" doesn't refer to a literal quantity. It's an expression that means, roughly, "not as true" or "not having as much of the essence of a/an ____".
Since that's an awkward definition, here is an example:
My grandfather thought that crying made you less of a man. (i.e., like "less manly")

Much more importantly, "smaller" vs. "less of a" is there just to distract you. You don't actually need it to solve the problem.
* You can eliminate a/b/c because the comparison has two possible meanings: (1) commitment to work vs. commitment to family, or (2) young people's commitment to work vs. their parents' and grandparents' commitment to work.
* You can eliminate E because "than" is there without "less".
