长难句是很多考生头疼的一项，主要是因为大家没有做过相应的长难句分析，今天小编整理了一部分长难句的分析，希望对大家以后长难句分析有所帮助。

　　1、The simultaneous production of masses of bamboo seeds in some cases lying 12 to 15 centimeters deep on the ground)is more than all the seed-eating animals(that) can cope with at the time, so that some seeds escape being eaten and grow up to form the next generation (Evans 1976).

　　分析：

　　这句话的主语The simultaneous production of masses of bamboo seeds比较长，含有两个of短语，系动词是is，表语是一个比较结构，在animals can之间是一个少了that的定语从句，so that 引导结果状语从句。

　　延伸：

　　状语从句：常见的状语从句有时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、让步状语从句、方式状语从句和比较状语从句。常用的连接词有when、where、because、since、if、whether、although、even if等。

　　2、The scent she carried in her samples and on her body was a message to the other bees that this was the one they were looking for.(剑4, General Training Test B section 3)

　　分析：

　　本句的主句为“The scent was a message to the other bees”;“she carried in her samples and on her body”为定语从句，做The scent的定语，关系词在定语从句中做宾语，因此被省掉;“that this was the one they were looking for”为that引导的同位语从句，做a message的同位语;“they were looking for”为定语从句，做the one的定语，关系词在定语从句中做for的宾语，因此被省掉。

　　延伸：

　　定语从句：定语从句是雅思阅读中非常常见的一类句型，分为限制性定语从句和非限制性定语从句。一般绝大多数定语从句都是限制性定语从句。定语从句的关系词有:who、whom、that、whose、which、when、where、why等。

　　3、James Boswell, his biographer, described the garret where Johnson worked as ‘fitted up like a counting house' with a long desk running down the middle at which the copying clerks would work standing up.(剑5, Test 1 passage 1)

　　分析：

　　本句主句为“James Boswell described the garret as ‘fitted up like a counting house' with a long desk.”;“his biographer”为James Boswell的同位语;“where Johnson worked”为定语从句，做the garret的定语，关系词为where; “running down the middle”为现在分词短语做定语，做a long desk的定语;“at which the copying clerks would work standing up”为定语从句，做long desk的定语，关系词为which。

　　延伸：

　　名词性从句：可以在复合句中担当主语、宾语、表语、同位语和介词宾语等成分，所以可以细分为主语从句、宾语从句、表语从句和同位语从句。常见的名词性从句的连词有三类：

　　a在句中不做成分的连词——that、whether、if、as if和as though;

　　b链接代词——what/whatever、which/whichever、who/whoever、whom/whomever和whose/whosever;

　　c连接副词——when/whenever、where/wherever、how/however、why。

　　4、Cheap labour may make Chinese clothing competitive in America, but if delays in shipment tie up working capital and cause winter coats to arrive in spring, trade may lose its advantages. (剑 6 Test 1 Passage 2)

　　分析：

　　这句话是由but连接的两个并列句，表转折关系，可以拆分为：

　　a. Cheap labour may make Chinese clothing competitive in America.

　　主语是Cheap labour，谓语是may make，宾语是Chinese clothing，宾补是competitive，状语是in America。

　　b. But if delays in shipment tie up working capital and cause winter coats to arrive in spring, trade may lose its advantages.

　　But并列连接词，表转折。这句话的主语trade，谓语是may lose，宾语是its advantages， if引导条件状语从句，从句主语是delays(in shipment)，谓语是由and连接的连个并列成分tie up and cause，宾语分别是working capital、winter coats。

　　延伸：

　　并列复合句：并列复合句大概可以分为并列关系、转折关系、选择关系、因果关系这四类。常见的连接词有and、but、however、so、or、for、nevertheless、not only…but also…、neither…nor…、both…and...等。

　　上面就是名词性从句、定语从句、状语从句和并列复合句四种长难句的分析，其实大家可以举一反三。希望对大家有所帮助。青岛雅思培训就选青岛朗阁。更多详情可以点击我们的在线老师进行咨询哦!
