英语的基本句式结构其实很简单：主谓宾和主系表。主谓宾是“谁-做-什么”，例如：比如“羊吃草”;“洁白可爱的小绵羊蹦蹦跳跳欢快活泼地在一望无垠的广阔草原上幸福愉快地吃着鲜嫩碧绿的青草”一样也是主谓宾，只不过多了一些修饰的词，句子的核心意思还是“羊吃草”。主系表是“谁-是-什么”，同主谓宾一样。在阅读中我们要很快的找出核心句子，不用每句话的意思都懂，但要知道这句话要表达的核心意思，即找到主谓宾或主系表的主体。
并列平行结构
在一个较长的句子中，并列平行的部分可能是几个独立的句子，也可能是几个并列的短语成分或者从句。如果并列平行的部分是几个独立的句子，也叫“并列句“。所以说，“并列平行结构”是一个更广泛的概念。本篇主要讲解并列平行的部分是几个并列的短语成分或者从句的这种情况。
中文：进一步展望未来，通过这个新时代所产生的巨大财富和新技术的结合.人类可望在太空建立一个浩大的可供千万人居住的世界。
英文：Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the construction of a vast, man-created world in space, home to thousands or millions of people, will be within our power.
结构分析：Combination of中的of有两个宾语:一是the great wealth，受定语从句this new age will bring的修饰，另一个是the technology,受定语从句it will provide的修饰:主句中的home to thousands or millions of people为world的同位语。

中文：但是随着人们重新关注杀虫剂对农产品的影响.以及红外线扫描技术的改进，Paley希望能重操旧业。
英文：But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation.
结构分析：with带两个宾语:renewed concern…和refinements...,整个短语作状语。
中文：那位中世纪的学者几乎没有尝试着去调查植物的解剖结构、生长机制，以及它们相互之间是如何联系在一起的。
英文：The medieval scholar made almost no attempt to investigate the anatomy of plants, their mechanisms of growth, or the ways in which they are related to one another.
结构分析：investigate后所带的宾语是三个平行并列成分.即:A, B, or C,具体来说这三个成分分别是:(一)the anatomy of plants.(2)their mechanisms of
growth,(3)or the ways in which they are related to one other。因为该句的谓语带有否定含义词no，所以用or,而不是and来把第三个并列成分和前两个连起来。
定语从句，并且会用例句来具体分析句子结构。看完本篇文章你绝对能搞定定语从句。
中文：利益是需要.渴望.关注.恐俱.一个人关心或想要的东西。
2
-
英文：Interests are needs, desires, concerns, fears一the things one cares about or wants.
结构分析:one cares about or wants是the things的定语从句。这个句子相对来说还是比较简单的，但其实复杂句也是一样的。
中文：另一个基于利益的过程叫做调解，在调解中一个第三方帮助冲突者，即在冲突中的双方.达成一致。
英文： Another interests based procedure is mediation, in which a third party assists the disputants, the two sides in the dispute, in reaching- agreement.
in which引出的定语从句in which a third party assists the disputants, the two sides in the dispute, in reaching-agreement是对mediation的解释，在定语从句中，the two sides in the dispute是disputants的同位语，同时也是插人语结构。
中文：在一个试验中，从6岁到22岁的实验对象看不同瞳孔大小的女性的脸的图画.并被要求从中选择更高兴的一个。
英文：In one experiment, subjects aged 6 to 22 were shown drawings of female faces that had different sized pupils, and asked to choose the one which was \"happier\".
3
-
全句主语是subjects，有两个并列谓语were shown和and asked，都是被动语态，that had different sized pupils是定语从句做drawings of female faces的定语，which was “happier”是定语从句做the one的定语，过去分词短语aged 6 to 22是subjects的后置定语。
中文：贝斯.以色列医院为每一位病人指派一名责任护士.责任护士要与指派给她的病人做深度交谈，并对病人的身体状况做全面记录.内容包括从病史到病人情绪的一切事情。
英文： At Beth Israel each patient is assigned to a primary nurse who visits at length with the patient and constructs a full-scale health account that covers everything from his medical history to his emotional state.
主从复合句。主句为At Beth Israel each patient is assigned to a primary nurse; who引导的定语从句修饰nurse.其中两个谓语visit和construct由and连接;that引导的定语从句修饰account,
插入语的标志
(1)插人语结构前后用逗号断开.如:The book, I think, doesn't provide information
about the population in that area.其中.插入语结构I think便是这种特点。
4
-
(2)插人语结构前后用破折号断开，如:The paper said the volcano destroyed most-if not
all-of the buildings and construction on the island。其中，插入if not all就属于此类结构。
对付插人语的办法是先略去不读。插人语常常插在主语和谓语之间.也可以插在句子中其他两个句子成分之间。有的插人语比较长，如果对插人语特别注意，会造成原来句子主要意思的中断，造成理解困难。而插人语常常是不重要的内容，所以应先略去不读.这样被分隔的两个句子成分就接上了。
中文：在相互依赖的关系中.例如，劳资关系或在一个家庭或一个组织中，谁更有力量的问题就转换成谁更少依赖于另一方。
英文：In relationships of mutual dependence, such as between labor and management or within an organization or a family, the question of who is more powerful turns on who is less dependent on the other.
结构分析：such as between labor and management or within an organization or a family是插人语，同时也是举例说明，是不重要的内容.可以先略去不读。全句的谓语是turns on, the question of who is more powerful是主语.宾语从句who is less dependent on the other是turns on的宾语。
中文：在发展中国家，在那里，至少有16个城市在近10年之末人口会超过1200万，不优先考虑公共交通是灾难性的。
5
-
英文：In developing countries, where at least 16 cities are expected to have more than 12 million people each by the end of this decade, failing to give priority to public transport would be disastrous.
结构分析：where at least 16 cities are expected to have more than 12 million people each by the end of this decade是插人语，是一个定语从句，修饰developing countries。全句主语是动名词短语failing to give priority to public transport.
中文：因此.像木屏风一样，Fanwall屏障可以被建造，不需要昂贵的混凝土的地基，加快了建造时间，降低了费用。
英文：Therefore, like the timber barriers, the Fanwall barrier can be built without expensive concrete footings or piles, speeding the construction time up and reducing costs.
结构分析：can be built是被动语态，like the timber barriers是介词短语做状语，speeding the construction time up and reducing costs是分词短语做状语。
中文：在希腊失去了独立后，古代奥运会在公元393年被罗马皇帝Theodosius废除了。
英文：The ancient Olympics were abolished by the Roman Emperor Theodosius in 393AD, after Greece had lost its independence.
6
-
结构分析：were abolished是被动语态的过去式形式。after引导一时间状语从句。罗马皇帝不认识，采用首字母提炼法T。
中文：假如不那么做，你可能被送上法庭。到时如果你不能向法庭证明你有理由可以不系安全带.你将会被罚款。这一点你必须牢记在心。
英文：Remember you may be taken to court for not doing so, and you may be fined if you cannot prove to the court that you have been excused from wearing it.
结构分析：本句为一个祈使句:remember的宾语由and连接的两个宾语从句担任;第二个宾语从句为一个主从复合句：if引导一个状语从句，而that引导的从句为prove的宾语。
本篇文章将分析雅思阅读难句中的状语从句，并且会用例句来具体分析句子结构。希望对广大考生有所帮助。
中文：虽然当对错在法律中正式规定时，通常是很直截了当的，但其他的对错采取的是非书面的、社会接受的行为标准，例如:互惠，先例，平等和资历。
英文： Although it is usually straightforward where rights are formalized in law，other rights take the form of unwritten but socially accepted standard behavior, such as reciprocity, precedent, equality, and seniority.
7
-
结构分析：although引导一个让步状语从句，注意本句的最后有一个such as,是例如的意思，后面的内容往往是举例说明，是属于不重要的内容，可不作为阅读的重点.socially accepted是standards of behavior的前置定语。
中文：特别是当父亲们对孩子们的需要负更大责任时，他们又更高的婚姻满意程度。当父亲们参与更多时.他们更高兴。
英文：There is also higher marital satisfaction for fathers, sepecially when they take more responsibility for the needs of their children fathers are happier when they are more involved.

中文：在米兰附近的伊斯普拉的欧共体科学实验室进行太阳能实验的欧洲经济共同体资深科学家认为，只要略为增加欧洲经济共同体在利用太阳能方面的研究经费.就能使这方面的研究提前20年取得突破。
英文：A breakthrough in the provision of energy from the sun for the European Economic Community (EEC) could be brought forward by up to two decades, if an modest increase could be provided in the EEC's research effort in this field, according to the senior EEC scientists engaged in experiments in solar energy at EEC's scientific laboratories at Ispra ，near Milan.
结构分析：全句主干为:“A breakthrough... could be brought for ward……;主语breakthrough被介词短语in the provision of……European Economic Community 8
-
(EEC)修饰.而provision又被两个介词短语所修饰:一是在逻辑上与之构成直接宾语的of energy from the sun,另一个是目的状语for the European Economic Community。if引导的从句为主句的状语:according to引导的介词短语也作状语，其中过去分词短语engaged in experiments in solar energy at EEC's scientific laboratories at Ispra，near Milan修饰scientists.作定语。
1.倒装句最常见的就是以only为首的句型，这种倒装句也会相对简单一点。
中文：写美国母亲的书很多，只是最近的文学才开始关注父亲的角色。
英文：Although numerous books have been written about American mothers, only recently has literature focused on the role of a father.
结构分析：第二个分句由于把only放在句首以强调recently，所以使用了倒装语序。主句的正常语序应为literature has only recently focused on the role of a father.
2.以never, little, often, not only, not until, hardly, scarcely等词引导的句子。
中文：我们不仅需要使纸张能被收废纸的人得到.而且纸张需要被分成不同的类别。
英文：Not only do we need to make the paper available to collectors but it also needs to be separated into different types.
9
-
结构分析：not only位于句首，引起前面的句子倒装。正常的语序是we need to make the paper available to collectors;
as或neither/nor引导的句子
The average air temperature at the surface of the earth has risen this century, as has the temperature of ocean surface waters.
4.某些让步状语从句
In addition, difficult as it is to believe, there are desert fishes that can survive through years of drought in the form of inactive eggs.
而且，尽管令人难以置信，还是有沙淇鱼类能以非活性卵的形态幸免于多年的干旱。
句子中as(= although/though,“尽管”;“虽然”)所引导的是让步状语从句。实际上.difficult as it is to believe= Although/Though it is difficult to believe.
