[求助]再问than比较结构的省略问题

28. economic growth will proceed at a more moderate pace than in the first quarter of this year.

251. The gyrfalcon, an Arctic bird of prey, has survived a close brush with extinction; its numbers are now five times greater than when the use of DDT was sharply restricted in the early 1970's. .

98．the world's capital markets are more closely integrated than ever before

112. Domestic automobile manufacturers have invested millions of dollars in research to develop cars even more gasoline-efficient than those at present on the road

补充those是因为是不同东东在不同时间的比较

198. Although Napoleon's army entered Russia with far more supplies than for any previous campaign， it had provisions for only twenty-four days.

30． No less remarkable than the development of the compact disc has been the use of the new technology to revitalize, in better sound than was ever before possible。

253. Analysts blamed May's sluggish retail sales on unexciting merchandise as well as the weather, which was colder and wetter than usual in some regions, slowing sales of barbecue grills and lawn furniture.

MM问题问的好呢!我不是大NN,也不是小牛牛,试着选会的答一下

than usual/ever before/necessary都是比较固定的搭配,MM问的30题中的用法我前几天也在想一直没找到合理的解释,有待NN指教一下

28主语的比较,我倒觉得应该在than后补上did因为主从句的主语谓语一致,且主语部分只用简单的adj做定语,所以应该是可以省略,但后面的时间状语是in the first quarter of this year与主句的will时态不同,按道理应该要补齐did的

251there be 句型的主语比较,主谓且都一致,这里我想than后面没有补出是因为when从句中已表达了完整的过去时态,如果再补出就显得笨拙

98/253如上说应该是固定用法

112主要是限定的问题,those指定cars 但由于前面所说的cars与后面不同前面的是将要产的,而后面的是已经出产的,现在投放市场的cars,我认由于前面有develop cars所以比较的是宾语不用补出动词

198.for 前省略了supplies实质比较对像是supplies.than后面的for 仍然是起限定作用,比较对像是宾语的补语，不需要补出动词

一点想法，不当之处欢迎各们大ＮＮ，小ＮＮ指正，同问３０的was ever befor possibe

我也不是大N或小N

来猜测一下

30是个倒装句

正常的语序是:  the use of the new technology to revitalize has been  no less remarkable than the development of the compact disc, in better sound than was ever before possible

ever before 提示了是与过去做比较,比较的是the use,所以用was

同意是与use作比较

但关于是was的补出,刚才去google搜了一下发现90%的句子中用的都是用than ever before的固定形式

只有在如下情况中补出了was

1.These scientific breakthroughs have enabled scientists to paint a much more detailed picture of climate change than was ever before possible.

2.It combined the labor of more than a single life, and has required the investment of more capital than was ever before risked in a single literary enterprise of its kind in this country

4.However, in the late 1800s a British official stationed in China, George Carter Stent, published a paper giving more information on this subject than was ever before generally known in the Western world

综上小结一下:1.当ever before后面紧跟possible结尾时补出was

                      2.当ever before后有分词时补出was

至于原因是什么,不知道,呵呵,希望大家一起来讨论一下

呵呵，我前天刚问了这个问题，据说是：句子意思清楚的时候可以省略than后面的动词

在这个句子中，后面的时态与前面的时态不一样，所以要补出was的吧

另外观察你给出的句子，被比较前一对象是主动，后面的是被动的时候，也要补齐动词，才不会有歧义

MM说的是当比较对像是主语且主句没有宾语的时候从句的动词可以不补出

但是than ever before/usual/necessary是比较固定的搭配一般这样的结构than后面是没有动词的

如Right now the scientists are out on Expedition 312 to study the deepest layers of ocean crust by drilling deeper than ever before.

再如Today's threats spread further and faster than ever before

在你给的这两个句子里，被比较的对象本来就是时间:

right now和even before

today和ever before

其他地方是相同的，当然就省略了

我觉得是根据句子意思判断的

如果说那两个例子中的比较像是right now 和ever before

拿例子二来举例它的比较对像是threats小有不同的只是它的定语一个是today一个是ever before

所以我说是根据句子意思判断的

仔细读句子，就能明白比较的对象:today的 threats和  ever before 的threats
