英语题求讲解

The committee, ______noted professors and experts, will make a thorough
investigation intothis accident.
A. consistingof B. forming of
C. composed D.composing
这道题为什么选C啊？求讲解，谢谢！

Answer 1

此题应该选择 A 项 consisting of，选择 C 项是错误的。

【解析】

　　动词 consist、form 和compose 都可以有“构成”的意思，consist 和 compose 都可以表示“由人员构成”，form 则表示“构成某种东西”，因此B项不在选择之列。

　　这句话的主句是 The committee will make a thorough investigation into this accident，需要填空的部分的 __ noted professors and experts 是插入性非限制性定语。表示“由…人员构成”有两种说法：consist of 和 be composed of。因此，可以把它改为如下的两种非限制性定语从句表示“该委员会由著名的教授和专家组成”：

　　The committee, which (consists of) noted professors and experts, will make…
　　The committee, which (is composed of) noted professors and experts, will make …

　　第一种的主谓结构 which consists of 可以用现在分词 consisting of 取代，第二种的主谓结构 which is composed of 需要用过去分词 composed of 取代。可见，选项 C 的 composed 缺少介词 of，所以也不应该在选择之列。

Answer 2

The committee 与composed之间是被动关系，所以应该用be composed 被动形式

又因为______noted professors and experts整个成分是作定语，所以be动词要省略

The committee, composed noted professors and experts, will make a thorough
investigation intothis accident.
由指定专家和教授组成的委员会将对此事故做一次彻底的调查！

Answer 3

The committee, ______noted professors and experts, will make a thorough investigation intothis accident.
The committee which is composed of noted professors and experts will make a thorough investigation intothis accident.

这里committee 是被组成，由什么组成，现在是主语，谓语应当是被动形式；composed …是过去分词短语作状语，修饰committee。其他结构都不对。
