文有点长....下面是我上课时写到的题目
15. A careful analysis of the___b____ products on the market indicated that
our product lacked innovation and optional features.
(A) compete (B) competed
(C) competing (D) competition
我原本选C，但老师说答案是B
以下是老师的解释:
The word "competing and competed" are verbal adjectives derived from the verb
"compete."
Therefore:
Competed products
When “competed” is used as an adjective, it means "who/that is/are competed
over or hard to get."
The competed products = the products that are hard to get because everybody
wants to have it and compete for it.
Competing products
When competing is used as an adjective, it means "who/that is/are competing."
The competing products = the products that are competing with each other to
increase sales
我有问为什么不能选C，(我真的觉得C感觉很合逻辑啊)老师说因为后面有讲道自身产品的缺点，所以B会比C好。
但其实我自己有用google查了一下，查不到be competed over，想问大家，真的有这种用法吗?C真的不可以吗?

我觉得…他在讲三小 XD

这题目源自Dr. Lin Lougheed的(BARRON'S) 600 .... TOEIC一书(我手头的是第三版)。答案是B competinghttp://i.imgur.com/cirPBN4.png 题目http://i.imgur.com/to1vg2K.png 解答用Google Books(专找出版物)搜寻"competed products"，原则上是没有（有出现个位数笔数。点开来看的话其实是OCRtypo)"competing products"本身是惯用表达http://www.ldoceonline.com/dictionary/competing

换个老师呗 XD

谢谢大家，应该是题目key错，老师硬掰出来的解释XD 其实我之前有因为老师一直说错答案换老师了，这是第二个，没想到还是…

competing:它主动来跟你竞争，一般都是用这个competed: 它在那里，你跳下去跟它竞争，听起来好像似乎可能也通？但是！要这样用的话后面应该多接with！
