句子成分分析(while...for...) 下面一句摘自2014高考英语全国卷1的语法填空题:While there are amazing stories of instant transformation, for most of the changes are gradual and require a lot of effort and work, like cleaning up a pol...
对于句子“While there are amazing stories of instant transformation, for most of the changes are gradual and require a lot of effort and work, like cleaning up a polluted river”的成分分析如下:
1. While 作为连词,引导一个让步状语从句,表示“虽然,尽管”。在这个句子中,“While there are amazing stories of instant transformation”作为让步状语从句,表示尽管存在瞬间转变的惊人故事。
2. for 在这里并不是要删掉的部分,而是一个并列连词,用于连接两个并列的句子或句子成分,表示原因或理由,意为“因为”。但需要注意的是,通常“for”作为并列连词时,前面不加逗号,除非在特定的语境或为了强调。在这个句子中,“for most of the changes are gradual and require a lot of effort and work”是主句,解释了为什么大多数变化是逐渐的并需要大量的努力和工作。
3. “like cleaning up a polluted river” 是介词短语作状语,用于进一步举例说明“require a lot of effort and work”的具体内容,即像清理一条被污染的河流那样的工作。
进一步分析句子结构:
主句:for most of the changes are gradual and require a lot of effort and work
+ 主语:most of the changes
+ 谓语:are
+ 表语:gradual
+ 并列谓语:require
+ 宾语:a lot of effort and work
让步状语从句:While there are amazing stories of instant transformation
+ 连词:While
+ 主语:there
+ 谓语:are
+ 宾语:amazing stories of instant transformation
状语(举例说明):like cleaning up a polluted river
+ 介词:like
+ 动名词短语:cleaning up a polluted river(作为介词的宾语)
这个句子通过“While”引导的让步状语从句和“for”连接的主句,以及“like”引导的介词短语作状语,清晰地表达了虽然存在瞬间转变的惊人故事,但大多数变化是逐渐的,并需要大量的努力和工作,就像清理一条被污染的河流那样。
