[分析]
此句的主语为“a microcomputer”, 也有两个谓
语,即 locks 和 sets。
方法二:并列复合句的处理方法——找并列连词 ①The hot sun had caused the dough (面团) to double in size and fermenting yeast made the surface shake and sigh as though it was breathing. ②Miss Germaine’ s mother looked anxious through the wedding and Mr. Cordell’s parents are reported to be less than delighted.
placed upon his desk a large jar (罐子) filled with dried beans (豆), and invited the students to guess how many beans the jar contained.
[分析]
此句正常语序为: ...placed a large jar filled
[分析] 此句的主语为 Pasteur,谓语是 discovered,第
一个 that 引导的是宾语从句。 在宾语从句中 after 引导状语从 句, 第二个 that 引导定语从句。 第三个 that 引导同位语从句。
[名师指津]
that 在长难句里面用得非常多,所以正确
理解 that 引导的不同从句非常重要。
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,环环相 扣,使得考生搞不清楚整个句子结构。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 是整个句子的骨架,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。
2.分隔结构 为了调整语气和增加补充信息, 更主要的是为了平衡句 子结构,避免头重脚轻,使语意严密,结构紧凑,可将语法 关系密切的两个句子成分用其他语法成分分隔开来, 这就是 所谓的分隔结构。高考试题中出现较多的是插入语、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,只不 过它只是句子原有成分位置的调整,没有新增信息。
[ 分析 ]
Whereas 引导了一个从句,即 “a woman ’ s
closest female friend might be the first to tell her to leave a faLeabharlann Baiduling marriage”, 而“it wasn’ t unusual to hear a man say” 为主句,其中 it 为形式主语,真正的主语为不定式。 “he didn’t know his friend’s marriage was in serious trouble until he appeared one night asking if he could sleep on the sofa”为省略从属连词 that 的宾语从句, 从句中又含有 not ... until 引导的时间状语从句,时间状语从句所在的主、从句 中又各含有一个宾语从句:“his friend’s marriage was in serious trouble” (省略连接词 that);与“if he could sleep on the sofa” (从属连词 if)。
[ 分析 ] 首先找到并列连词 but ,推知: If you ask ... “Webster”为 but 连接的第一分句,“none of these men ... the Conqueror”为第二分句;第一分句中含 if 引导的条件状语从 句,从句中又含有 who 引导的定语从句;第二分句中含 who 引导的定语从句。
[分析]
第①句中的 and 和第②句中的 and 都是并列连
词,各自连接两个并列单句。
方法三:主从复合句的处理方法——找从属连词 Whereas a woman’s closest female friend might be the first to tell her to leave a failing marriage, it wasn’ t unusual to hear a man say he didn’ t know his friend’ s marriage was in serious trouble until he appeared one night asking if he could sleep on the sofa.
2.意群阅读法 一个句子可根据意思和语法结构分成若干小段, 每一小 段称之为一个意群。意群可以是一个词,一个词组或短语, 也可以是一个并列句的分句或复合句的主句、从句等。此方 法有助于提高阅读速度和理解的准确性。例如: ①When two cars travelling at 30 mh hit each other,② an unbelted driver would meet the windshield (挡风玻璃) ③with a force equal to diving headfirst (头向前地) into the ground from a height of 10 meters.
一般来说,复合句中的从句都是很常见的,考生比较熟 悉的,但很多时候不少考生分不清单词、短语和从句之间的 相互关系,这样会导致整个句子分析混乱。这时,考生应通 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。
[例 1]
What Winter knows of the 19yearold who
saved his life is only that he died in a car accident and that his family was willing to honor his wishes and donate his organs for transplantation (移植).
方法四:并列和主从复合句并存的处理方法 ——先读懂并列复合句,再看主从复合句 If you ask people to name one person who had the greatest effect on the English language, you will get answers like “Shakespeare” “Samuel Johnson”, and “Webster”, but none of these men had any effect at all compared to a man who didn’t even speak English — William, the Conqueror.
[名师指津] 补充完整省略成分,才能正确理解语境。
4.改变语序 改变语序主要针对倒装句式。 这种打破相对固定的常规 语序的做法,或是为了强调句子表达的重心,或是强调一种 表达语气,如虚拟语气、否定语气等。这些句子往往和一些 副词、连词相关,有明显的标志。
[例 5]
The professor marched into the lecture hall,
此句的主语为“many scientists”, 主语后跟一个
由 who 引导的定语从句。主句有两个谓语,即 are doubtful 和 say, say 后面又接了一个宾语从句。
②Some companies have made the manufacturing of clean and safe products their main selling point and emphasize it in their advertising.
[ 分析 ]
此句的主语为 “What Winter knows of the
19yearold who saved his life”,是一个主语从句,其中主 语从句里面又包含了一个由 who 引导的定语从句;is 为主 干句的系动词,后面的 that 引导两个并列的表语从句。
[名师指津] 要的一步。
[ 例 3]
The idea of returning to the basics in the
classroom — a notion (概念, 观点) which, incidentally (顺便 说一下 ), has been quietly supported for years by many respected teachers — is finally gaining some currency (流行) with school administrators (管理者).
[分析] 两个破折号中间的内容是对前面的补充说明。
[名师指津]
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 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。成 分省略一般和从句相结合,一正一反,使句子富于变化,增 强表现力。例如在以 than, as 引导的比较状语从句中,一些 成分往往被省略,而这会给理解带来一定的影响,而且这类 句子出现频率较高,考生需要熟记。

依据句子成分,学会分析长难句
一些复杂的长难句一方面是制约考生快速理解文意、准 确解题的“拦路虎”,另一方面又是彰显考生写作功底的 “走秀台”,在某种程度上来说,对长难句的分析与掌握已 成为区分考生成绩优劣的“分水岭”。其实,长难句并不可 怕,在正确划分句子成分的基础上,运用一定的“拆分”技 巧,化繁为简、化长为短,其意立马显现。所以,无论是从 学语法的角度,还是从英语综合素养的角度,都有必要给考 生补上这欠缺的一课。
①However, many scientists who specialize in ageing are doubtful about it and say the human body is just not designed to last past about 120 years.
[分析]
with dried beans upon his desk ...
[名师指津] 还原为正常语序是理解语境的关键所在。
二、长难句的突破策略
1.结构分析法 所谓结构分析法,就是通过语法分析,迅速弄清句子的 结构,把握住句子的基本框架。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。
分析长难句时找出主干句的谓语是至关重
[例 2]
Pasteur discovered that heating the wine gently
for a few minutes after it had fermented (发酵) would kill off the yeast (酵母菌) that was left in the wine, with the result that the wine would remain fresh for much longer.
[ 例 4]
I look forward to seeing these views taken
further, and to their being challenged by the other participants.
[分析]
and 后省略了重复成分 look forward,读题时
应将被省去的部分补全理解。
[分析]
此句的主语为“Some companies”,句中有两个
谓语,即 have made 和 emphasize。
③At the press of a button, a microcomputer locks all other floors chute (道) doors and sets the recycling container turning until the right box comes under the chute.
