175 .Doctors still know little about how the Listeria bacterium is spread and why the disease it causes, listeriosis, afflicts some people in a contaminated area while sparing many others. （当。。时）



Ms. Chambers is among the forecasters who predict that the rate of addition to arable lands will drop while the rate of loss rises.　（当。。时）


    OG233: .Recently implemented “shift-work equations” based on studies of the human sleep cycle have reduced sickness, sleeping on the job, and fatigue among shift workers while raising production efficiency in various industries ( 当..时..)


三个题的考点都是在考while的意思。 如何判断是接分词还是接动词？？ 也就是说什么时候是" when" 的意思设么时候是" but" 的意思????     .我觉得以上几题都可以做为但是解那么选项就不同了. 请指教


195. The American Medical Association has argued that the rapidly rising costs associated with malpractice litigation are driving doctors from the profession and that reform of the tort system is imperative to bring malpractice insurance premiums under control.


这句话什么意思, 句子结构拆不出来??


214.    Although the government or industry usually sets minimum standards for transportation industries, no such standard has been set for qualifying to be an engineer on a train. (A-P1-214)

    Rules banning cancer-causing substances from food apply to new food additives and not to natural constituents of food because the use of such additives is entirely avoidable. (A-P1-39)

fficeffice" />    这两个句子都是有such 后面没有什么as之类的搭配. 为什么不像平常一样用the.什么时候就要必须用such 什么时候可以不用such??? such和the的用法区别是什么???? 非常感谢~~~

以下是引用麻集爱在2004-4-2 22:45:00的发言：
175 .Doctors still know little about how the Listeria bacterium is spread and why the disease it causes, listeriosis, afflicts some people in a contaminated area while sparing many others.

主语是doctors，谓语know 后面一个宾语从句，说明know about 的内容，how从句中是两个并列，Listeria bacterium如何传播和为什么the disease sparing many others（在其他许多地区传播）却afflicts some people in a contaminated area ，listeriosis 做disease的同位语，是bacterium cause的疾病

    

while 如何判断是接分词还是接动词 也就是说什么时候是" when" 的意思设么时候是" but" 的意思????     这句话翻译不明白. 请指教谢谢

195. The American Medical Association has argued that the rapidly rising costs associated with malpractice litigation are driving doctors from the profession and that reform of the tort system is imperative to bring malpractice insurance premiums under control.

这句话什么意思, 句子结构拆不出来??

that从句的并列从句1中associated with malpractice litigation修饰cost

１９５　ok 了，3Q


１７５　没回答道我问的地方阿？　我明白这里翻译成当。。时，但是考试的时候谁知道它是 ｗｈｅｎ的意思？这里如果作为but的意思，while后面连spare的选项是不是也对？我把所有这类的问题都找出来了，都是相同的问题 请比较一下。给个解释。


谢谢

used to emphasize the difference between two situations, activities etc



我觉得前面这3个例子更接近于用的这点，我觉得表示 emphasize the difference


赫表示during the time that something is happening 在用法上并没有什么很本质的区别阿


They were killed while attempting to reach the summit.


这句里面，while =when 只不过省略形式而已


不知道我是不是理解你的问题



    


They were killed while attempting to reach the summit.

非常感谢。剩下的214 ：such 的用法 有人回答么？？？

bebexu

such A  =这样的A

是用于表明所出现的A

就好像 He pass......, however do so..........

这里的so 用法和such 一样

tianwan

1,the: means it is the exact antecedent one it refers to.

such: means it is something of the same kind of the antecedent one it refers to, not necessarily  the exact antecedent one.

2, If 'while' is in the latter clause, only when 'while' means 'when', you can use the participle structure following it. While 'while' is in the first clause, you have to judge its meaning by logic sense.

Open to discussion......
