3.                 The airline industry is cutting its lowest discount fares more widely, more substantially, and earlier this year than it normally does at the end of the summer, a time during which travel usually decreases and the industry uses some lower fares for the attraction of passengers.fficeffice" />

(A) during which travel usually decreases and the industry uses some lower fares for the attraction of

(B) during which travel usually decreases and therefore the industry will use some lower fares for the attraction of

(C) in which travel usually decreases and in which the industry therefore uses some lower fares attracting

(D) when travel usually decreases and the industry uses some lower fares to attract（D）

(E) when travel usually decreases and therefore the industry will use lower fares for the attraction of

    

答案D本身没有疑问。一个use sth to do sth 就可以搞定。我的问题是：假如D中的when 用in which 或during which 替代会不会不好？

rt316

time只能用when做定语修饰

ecsniffer

感觉不好


如果改为in which 或者during which,


则变为in a time，during a time，这种表达方式有点怪


如果原句变为


ten days in which........则可以，因为in ten days这样表达好


a period during which...也可以，因为during a period这样也可以接受


请指教！！

谢谢楼上两位。我也有这种想法，就是不敢确定。刚才查了大全。虽然没找到in which 但是找到了during which, 证实了ecsnifferMM的看法。附上一题：

    

1.                             After the Colonial period’s 50 percent mortality rate, life expectancy improved for children, but as late as the nineteenth century about one child in three died before reaching the age of six.fficeffice" />

(A) After the Colonial period’s 50 percent mortality rate, life expectancy improved for children, but

(B) Even though children’s life expectancy, which improved over the Colonial period’s 50 percent mortality rate,

(C) Although life expectancy for children improved after the Colonial period, during which the mortality rate was 50 percent,

(D) While there was an improvement in life expectancy for children after the 50 percent mortality rate of the Colonial period, still（C）正确答案。

(E) Despite children’s life expectancy improvement from the Colonial period’s 50 percent mortality rate,

    

不过我又想到一个问题：

    

3.                 The airline industry is cutting its lowest discount fares more widely, more substantially, and earlier this year than it normally does at the end of the summer, a time        when travel usually decreases and the industry uses some lower fares to attract

passengers     假如把这句话中的a time 去掉，这里的应该用什么？感觉还是when 比较好。

    

如果改成which 前面介词用at 好像很不爽呀。

    

又如果直接用which, 好像也不对，at the end of the summer 还原到句子中应该是时间状语成分.

    

思维极度混乱，不知道自己的想法对不对，还是又钻牛角尖了。请指教。

at the end of the summer, a time        when travel usually decreases and the industry uses some lower fares to attract


a time 后面的一串就是个独立成分，用来修饰at the end of the summer 这个时间状语的。


如果直接用when 就应该是at the end of the summer when


如果不用when的话，你就应该找一个介词短语，in/at/during ..which= at the end of the summer

以下是引用bebexu在2004-4-2 12:24:00的发言：
at the end of the summer, a time        when travel usually decreases and the industry uses some lower fares to attract



a time 后面的一串就是个独立成分，用来修饰at the end of the summer 这个时间状语的。


如果直接用when 就应该是at the end of the summer when


如果不用when的话，你就应该找一个介词短语，in/at/during ..which= at the end of the summer


    

谢谢bebexuMM确认。理论上我也认为 可以用一个介词短语替代when， = at the end of the summer. 比如你说的in/ at /during.     实际操作中感觉这个句子很不爽呀。


at the end of the summer,     when travel usually decreases and the industry uses some lower fares to attract     感觉是可以的。


at the end of the summer,        at/ in/ during    which travel usually decreases and the industry uses some lower fares to attract     感觉这个句子有点不清不楚的。从语感上来讲，我就是觉得这个句子不好。但是理论感觉没错。不知道会不会是因为用when 表达的概念比 at which 和in which 清晰。优先使用?


实际上，我查了大全里面的句子，没找到用in which 来替代when 的。during which 的倒是不少。不知道会不会是因为in which 本身用来替代when 会unclear, (是不是因为 in which 常用来表达where 所不能表达的意思的原因？ )         而during 后面总是跟一段时间不会有歧义？


hope I can make sense.

weiyu

谢谢weiyu, 这样记住比较好。by the way, 最后一个an age in which 用an age, during which 应该也可以吧。好像an age when     不大好吧。


还请确认。
