21.   In the face of widespread concern about environmental waste, compact disc manufacturers are attempting to find a replacement for the disposable plastic box in which they package their product.

(A) the disposable plastic box in which they

(B) the disposable plastic box where they where错

(C) a disposable plastic box in which to

(D) disposable plastic boxes inside which they（A）inside错

(E) the disposable plastic boxes in which to

这题我选C，在A/C/E中选

我感觉句子中要求的是泛指的盒子 所以我选C  a disposable plastic box

哪里不对呢

in which to 为何不对呢  

谢谢

这里指的是一类所以以用the disposable plastic 或者disposable plastic boxes后面用的是in which引导的定语从句，如果用不定式做定语的话，就不能用in which,另外还要注意不定式的逻辑主语，这道题倒是逻辑主语是存在的。

在阅读中找到类似的句子

At a time when the balance of power in Europe and Asia was rapidly shifting, the services lacked any precise statement of United States foreign policy from the National Security Council on which to base future programs.

不知何时可以这样用 何时不能

关键是a disposable...错了吧，后面既然有定语从句修饰，就是特指应该用the。

rhod

这里应该不是泛指的意思，而是特指某种产品，所以用the更合适。

in which to不是不可以，只是大全上没有先例，未划线部分到是出现过一次，但应该是连接句子的情况更多。

rhod

同感。

请问什么时候可以用in which to do sth. 什么情况下不能用呢

谢谢

20. An array of tax incentives has led to a boom in the construction of new office buildings; so abundant has capital been for commercial real estate that investors regularly scour the country for areas in which to build.

不定式做定语有两种情况，1、修饰抽象动词，作为抽象动词的解释。2、和被修饰名词有着动宾关系，这时候不定式前通常有介词。

在in which to结构中的不定式显然不是做前面名词的定语，而是句子或从句的宾语补足语，因为不定式的发出者是句子或从句的主语，which是代词。而在此句中就存在着歧义，

In the face of widespread concern about environmental waste, compact disc manufacturers are attempting to find a replacement for the disposable plastic box in which to package their product.

此句中的不定式的逻辑主语是compact disc manufacturers，用不定式的话，变成了说 manufacturers are attempting to find a replacement (for the disposable plastic box) to package their product in.没有A中的定语从句修饰对象明确。

以下是引用paopao在2004-9-1 14:14:00的发言：

21.   In the face of widespread concern about environmental waste, compact disc manufacturers are attempting to find a replacement for the disposable plastic box in which they package their product.

(A) the disposable plastic box in which they

(C) a disposable plastic box in which to

我感觉句子中要求的是泛指的盒子 所以我选C  a disposable plastic box

in which to 为何不对呢  

首先我们来确定句子的意思，are attempting to find a replacement for the disposable plastic box in which they package their product. 句中disposable plastic box显然是厂家已经在用的包装，换言之，原文想表达的意思是：厂家想找一种可以替代现有包装的替代品，而in which to package their product 中的to使得句子意思改变成：厂家想找一种可以替代打算(还没有启用)启用的包装的替代品，显然，句子意思被改变了；而且，如LES和leeon所言，the和a分指特指和泛指，而定从修饰的名词一般作为特指名词，所以，由此也可以迅速排除C。
