高中英语必备的长难句分析(附历年高考英语长难句100例)
高中英语必备的长难句分析(附历年高考英语长难句100例)阅读理解得分低，往往是因为文章看不懂，文章中的句子之所以难以理解，有许多原因，其中一个主要原因是句子太长或者句子结构复杂。
句子过长或者复杂通常是该句除了主干之外还包含了一些附加部分，如插入语、同位语、分隔现象、各种从句或较长的非谓语动词短语等等。
下面我们来谈谈几种英语阅读长难句的处理方法。
如何处理长难句？1找谓语，找定语一般情况下，一个谓语形式的动词对应其动作的发出者(主语)，我们可以根据谓语动词的意义来确定其主语。
而且，如果一个句子中出现两个或两个以上的谓语形式的动词，则该句可以是并列句或复合句(并列谓语动词的情况除外)。
如：People feared that weakening a 21-year-old ban on the sale of ivory would encourage illegal hunting and hurt elephant populations.【句意】二十一年来，象牙交易一直被明令禁止，人们担心削弱这一禁令会助长非法捕猎，导致大象数量减少。
【分析】that 引导宾语从句，从句中谓语动词是encourage和hurt，根据逻辑意义，可知encourage和hurt 的主语是动名词短语weakening a 21-year-old ban on the sale of ivory。
2提主干，去枝叶一般情况下，一个句子中的主句所表达的信息为主要信息，从句、状语和定语等所表达的信息为次要信息。
若句子的主干提炼不出来，就不能完全把握句子的核心意义，从而导致思维混乱，主次不分。
如：Economists from the University of Sussex analysed findings from the National Longitudinal Study of Adolescent Health, a 15-year research project charting the fortunes of a group of thousands of teenagers who attended high schools in the US in the mid-1990s.【句意】来自萨塞克斯大学的经济学家们分析了国家青少年健康纵向研究的研究结果，这项研究是一个历时15年的课题，它记录了数千名在美国20世纪90年代中期上中学的一组青少年的财产情况。

高考英语阅读理解长难句分析+附重点词汇用法
高考英语阅读理解长难句分析+附重点词汇用法长难句1：This tension between what we feel we can have and what we’re seemingly able to have is the niggling suffering, the anxiety we feel. This is where we usually think it’s easier to just give up. But we’re never meant to let go of the part of us that knows we can have more. The intelligence behind that knowing is us —the real us. It’s the part that believes in life and its possibilities. If you drop that, you begin to feel a little “dead”inside because you’re dropping “you”.译文：我们自己认为能拥有的和我们实际能拥有的之间的矛盾，总是让我们焦虑，备受折磨。
在这种处境中，我们通常会觉得还是放弃更容易吧。
但是我们永远不会放弃一部分自我，相信我们可以拥有更多的那部分自我。
“相信”背后的智慧就是“我们自己”——真正的“自己”。
正是这部分“自己”相信生活，相信生活充满可能性。
如果不再相信，心里会感觉有些东西在慢慢消失，因为你放弃了“你”。
点拨：benever meant to dosth：决不会做某事let goof：释放，松手放开drop：放弃dead：死气沉沉的，无生机的长难句2：Failure is probably the most exhausting experience a person ever has. There is nothing more tiring than not succeeding.译文：失败可能是一个人一生中最疲惫的经历。

2021高考英语典型技巧01 长难句的分析与理解(解析版)
备战2021年高考英语二轮复习之阅读理解“典型技巧”高效练典型技巧01 长难句的分析与理解【技巧释义】高考阅读理解的文章一般会有一些结构复杂的句子，增加了句子的长度和难度，干扰了学生正常的阅读速度和思维方式。
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 w here 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。
高考英语阅读长难句分析方法与实例
高考英语阅读长难句分析方法与实例一、长句难句是如何产生的1、分支多，短语多英语句子主干是构成五种基本句型的基础：这五种结构之所以为基本结构，因为这五种结构是构成英语语句子的主干，英语长句都是通过这五种基本结构演变而来的，掌握句子五种基本结构是分析和理解英语句子的基础。
英语句子的特点是除了词可以做句子成分外，短语和句子都可以做句子成分。
就算是一个单句，如果都是以短语为句子成分，再加上句子如果分支较多的话，也可以构成比较复杂的句子。
2、分句多，从句多英语复合句可分为并列复合句与从属复合句。
并列复合句是在结构和意思上都可以相互独立的两个或多个单句构成的复合句；从属复合句是一个句子做另外一个句子的句子成分，两个句子不可以相互独立成为句子，如果两个句子拆分会导致句子意思不完整，或句子成分残缺。
在英语复合句中特别是从属复合句，从句中还可以有从句或其它并列句，有些复合既有并列句，又有从属句。
复合句也是构成英语长句难句的重要原因。
二、长句难句的分析方法长句难句的分析方法可以概括为：先主句再从句，先主干再分支。
先主句再从句就是对有从句的长句难句，先不看从句，先找出句子的主句并分析主句的句子主干，再分析从句；先主干再分枝就是先分析主句与从句的句子主干，再分析句子的分枝，句子的分支主要是指定语和状语。
三、长句难句分析实例实例1：Shackleton, a onetime British merchant-navy officer who had got to within 100 miles of the South Pole in 1908, started a business before his 1914 voyage to make money from movie and still photography.本句是含有定语从句的复合句，根据先主句再从句的分析方法，我们先去掉从句（who had got to within 100 miles of the South Pole in 1908），把句子简化为：Shackleton, a onetime British merchant-navy officer started a business before his 1914 voyage to make money from movie and still photography.再根据先主干再分支，把句子分支(主语同位语a onetime British merchant-navy officer，时间状语before his 1914 voyage，目的状语to make money from movie and still photography)都去掉，进一步简化为：Shackleton started a business.那么这个句子的几层意思就很明确了①Shackleton何许人，a onetime British merchant-navy officer who had got to within 100 miles of the South Pole in 1908②做了什么事，Shackleton started a business③什么时间做的，其目的为何 before his 1914 voyage to make money from movie and still photography实例2：These local citizens now have to balance their traditional self-supporting hunting lifestyle with the lifestyle offered by the modern French Republic, which brings with it not only necessary state welfare, but also alcoholism, betrayal and even suicide.本句也是含有定语从句的复合句，根据先主句再从句的分析方法，先去掉从句（which brings with it not only necessary state welfare, but also alcoholism, betrayal and even suicide.），再根据先主干再分支，把句子分支（offered by the modern French Republic过去分短语做定语）去掉简化为：These local citizens now have to balance their traditional self-supporting hunting lifestyle with the lifestyle.那么这个句子表达了两层意思：①当地市民得在传统自给自足的狩猎生活与现在生活方式之间找平衡。

长难句分析一、长难句的分类1、带有较多成分的简单句。
如：Having chosen family television programs and women’s magazines，the toothpaste marketer，for instance，must select the exact television programs and stations as well as the specific women’s magazines to be used.例如，决定选择家庭电视节目和妇女杂志后，牙膏经销商还必须挑选出要用的确切的电视节目和电视台，以及那些具体的妇女杂志。
在这个有30多个词的简单句中，动词-ing形式短语用作时间状语，不定式to be used修饰的不仅是women’s magazine，而且还修饰television programs and stations.exact television同时修饰programs和stations两个词，这在翻译中可以看出来。
插入语for instance把主语和谓语分隔开了。
2、含有多个简单句的并列句。
如：In the1970s he was a surgeon at Yale，had a wonderful wife and five beautiful children，but he was terribly unhappy.在20世纪70年代，他在耶鲁当外科医生，有位出色的太太和5个漂亮的孩子，但他那时过得却很不开心。
在第二个并列句中，即在had前面省略了and he.Discrimination(歧视)isn’t their only concern；almost everyone testing positive for the Huntington’s gene(基因)develops symptoms(症状)during middle age，and doctors can do nothing to help.担心受到歧视并不是他们唯一的忧虑，几乎所有遗传性亨廷顿病基因检测呈阳性的人在中年时症状都会显现出来，而医生对此却无能为力。
三个分句均为简单句，分别用分号和and连接。
3、含有多个从句的复合句。
如：I can’t live in fear of the possibility that as the earth’s population grows and we use more and more of our nonrenewable(不能再生的)resources，our children may have to lead poorer lives.我不能总是生活在对这种可能性的忧虑中：由于地球上人口的不断增长，由于我们正在消耗掉越来越多的非再生资源，我们的孩子可能不得不过着更加贫穷的生活。
在possibility后由that引导的同位语从句中还含有一并列结构的时间状语从句：as…resources.However，those of us who are parents of children in this age group know that such offers are relatively rare and that many liberal-arts students(文科生)graduate with the belief that the prospective(预期的)workplace may not have a place for them.然而，我们这些有这个年龄段孩子的家长们都知道，这样的机会少得可怜；我们也知道，许多文科毕业生认为未来的就业市场没有他们的一席之地。
本句的主谓语是：those of us know。
know有两个由that引导的宾语从句，其中第二个省略了know。
在主句中还有一个定语从句修饰those of us，在第二个宾语从句中还有一个同位语从句修饰belief。
4、含有多个插入成分的句子。
如：His journey to the e-mail hell began innocently（无知地）enough when,as chairman of Computer Associates International，a software company，he first heard how quickly his employees had accepted their new electronic-mail system.他在电子邮件的地狱之旅是糊里糊涂开始的。
作为国际计算机联合公司这家软件公司的董事长，他当时还是第一次听说他的雇员们是多么快地就接受了他们公司的新的电子邮件系统。
as chairman of Computer Associates International是he的同位语，a software company是Computer Associates International的同位语，他们将从属连词when引导的时间状语从句的主语分隔开了。
5、并列复合句。
如：I have known changes for the better and changes for the worse，but I have never questioned the fact that whether I liked it or not，change was unavoidable.我经历过好的变化，也经历过坏的变化，但是我从来没有怀疑过这样一个事实，即不管我喜欢与否，变化总是不可避免的。
在but后的那个并列的分句中有一个同位语从句，其中还含有一个让步状语从句。
They also found that the bus conductor had a major role in preventing vandalism（故意破坏行为），and at the times he went up the stairs to the upper deck to collect fares，vandalism did not often occur.他们还发现公交车售票员在防止发生故意破坏方面发挥了重要的作用。
当售票员到双层公交车的上层收费时，破坏行为就不常发生。
在前一个并列分句中有一个宾语从句，在后一个并列的分句中有一个修饰times的定语从句，这个定语从句前省略了关系词that或when.二、长难句分析步骤1、首先确定句子是简单句、复合句或并列句。
2、如果是简单句，首先确定主谓结构；接着确定宾语和宾语补足语（如有的话）；然后确定定语和状语等次要成分，即找出主语、谓语和宾语各自的修饰语。
按照所确定的各个成分，给出全句大意（可用翻译法）。
译文意思应当通顺，并和上下文意义基本吻合。
如意义出入较大，文理不通，则分析可能有误，这时应考虑重新进行句子结构分析。
3、如果是并列句，首先应找出并列连词并把全句分解为若干个分句；接着按照简单句的分析方法再细分各分句的内部结构和句意；然后将全句综合考虑。
4、如果是复合句，首先找出从属连词并确定出主句，这时应特别注意连词省略现象和多义连词在句中的确切含义；接着按照简单句的分析方法再细分各分句的内部结构和句意；然后确定从句的性质，即该从句在句中修饰什么词语或结构；最后整体考虑全句大意，尤其要注意对修饰语的判断是否准确。
三、长难句分析的注意事项在分析句子成分时，还应特别注意下列几点：1、是否有同位语和插入语。
2、是否有省略、倒装和分隔等现象。
3、替代词的所指对象。
4、判断并列成分的层次。
5、句首的并列连词and、or、but、for通常起承上启下的作用，不要将他们归入后文的句法分析。
6、在从句多的句子中，从句中又包含从句的现象。
7、非限定动词短语在句中作次要成分（定语和状语）时又带着自己较长的从属成分，尤其是状语从句或宾语从句时的结构分析。
8、在有多个从句的复合句和并列句中，状语（单个词、短语或从句）究竟是全句的修饰语还是某个从句或词语的修饰语。
练习：1.Canada has vast areas of wilderness,from the Arctic north,where average winter temperaturesare usually minus20degrees centigrade,to the8,892-kilometre-long border with the USA to the south,which is the longest border in the world not defended by an army or the police.2.Montreal,a port in the province of Quebec,is the second largest city in Canada,and also thesecond largest French-speaking city in the world,Paris being the largest.3.As a modern,dynamic city,Montreal has a lively night scene,with many restaurants and clubs,as well as cultural and street festivals to ensure that no visitor is ever bored.4.It also has superb scenery,a beautiful harbour,and all the comforts of modern life andinternational cuisine,in addition to being close to some very popular ski areas.5.The waterfalls,the largest of which is shaped like a semicircle,are670metres wide,and fall56metres in an awesome white sheet of water.6.Although only a handful of people became successful,many stayed and built settlements in thearea,and there are now many museums showing what life was like back then.7.Indeed,sitting in front of the television watching a sports event,with a drink in one hand andsome fast food in the other,is very common in Australia.8.Another popular sport,cricket,is originally from the UK,and has been exported to andfollowed in countries influenced by it,such as Australia,India,Pakistan,Kenya and South Africa.9.I think that that that that that student wrote on the blackboard was wrong.10.Having chosen family television programs and women’s magazines，the toothpaste marketer，for instance，must select the exact television programs and stations as well as the specific women’s magazines to be used.11.Schools across China are expected to hire50,000college graduates this year as short-termteachers,almost three times the number hired last year,to help reduce unemployment pressures。
