考向17 长难句与复杂句子分析
一、长难句的常见形式
1．复合句
这些句子往往较长，一个从句套着另一个从句。其实，不管句子有多长、多复杂，它只由两部分构成，即主干和修饰成分。主干主要指主谓宾结构(如：I want a ticket.)或主系表结构(如：The man is a teacher.)。而修饰成分在句中只起修饰或补充主干的作用，它既可以是单词，也可以是短语，更常见的则是从句，尤其是定语从句和状语从句。应通过仔细分析，将每个修饰成分划出来，找出句子的主干，这样整个句子结构就清晰了。
I urge you to contact your state legislators to move this legislation forward so that this weekend will be one of the last times when we have to “fall back”．
分析：此句的主语为I，谓语是urge, so that引导的结果状语从句。在结果状语从句中when引导定语从句。
2．分隔结构
高考试题中出现较多的分隔结构是插入语、用破折号插入的新话题或补充信息。此外，还有一些句子成分(一般是定语)过长而出现后置，也可以看作是插入现象。
“The results are pretty exciting—strong levels of reductions—but there clearly are going to be things to be learned from the areas where the reductions are not as great.” said Penn State University professor Elizabeth McGraw.
提醒：分析长难句时务必注意这些非限制性修饰成分，它们打断了原来的行文逻辑，插入补充了一些额外的信息。
3．成分省略或倒装
在英语句子中，用词简洁是一条重要的修辞原则。省略主要是为了避免重复，突出关键词并使上下文紧密连接。有时为了强调句子表达的重心，对句子进行倒装。
By the end of the century, if not sooner, the world's oceans will be bluer and greener thanks to a warming climate, according to a new study.
分析：此句正常语序为： By the end of the century, if it is not sooner, the world's oceans will be bluer and greener thanks to a warming climate, according to a new study.
二、长难句突破策略
通过语法分析，迅速弄清句子的结构，把握句子的基本框架的基本步骤是：首先，判断该句是简单句、并列句还是复合句；然后，找出句子的核心成分，分清主语和谓语，再分清句子的附属成分。
方法一：较复杂单句的处理方法——找主谓语，即找主干成分
较复杂单句在高考试卷中经常出现，所以应引起同学们的足够重视。
(2020·浙江1月高考阅读C)A key skill set for success is persistence (毅力), a characteristic that researchers say is heavily influenced by fathers.
分析：主语是A key skill，谓语是is，表语是persistence, a characteristic是同位语，解释说明persistence。that引导同位语从句，解释名词characteristic。
方法二：并列复合句的处理方法——找并列连词
There was a bit of me that didn't want to love this when everyone else on the planet did, but the horror story is brilliant.
分析：句中的but是并列连词，连接两个并列单句。
方法三：主从复合句的处理方法——找从属连词
(2020·浙江1月高考阅读C)A key finding is that over time, children raised by an authoritative father were significantly more likely to develop persistence, which leads to better
