5、从句多的句子中，从句包含从句。长难句分析方法(一)找出句子的谓语和主语根据谓语动词来确定其主语，如果一个句子中出现两个或两个以上的谓语动词，则该句可能是并列句或复合句（并列谓语动词的情况除外）。People feared that weakening a 21-year-old ban on the sale of ivory would encourage illegal hunting and hurt elephant populations.解析 that 引导宾语从句，从句中谓语动词是would encourage和hurt，根据逻辑关系可知，encourage和hurt 的主语是动

6、名词短语weakening a 21-year-old ban on the sale of ivory。翻译 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。(二) 提取句子主干成分，祛除多余成分一般情况下，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。Economists from the University of Sussex analysed findings from the National Longitudinal St

9、联词来连接。如果我们找准这些关联词，就能够弄清楚句与句之间的逻辑关系，弄清楚主句的意义和各从句的意义，从而长句就容易理解了。要掌握此方法必须对英语中常见的关联词熟记于心。Whether you get along well with your professors or not has a huge effect on your self-growth as it is a measure of how well you can respect authority and obey requirements.解析 此句为主从复合句，句中Whether引导主语从句，as 引导原因状语从句，how

10、 well 引导的宾语从句作介词of 的宾语。翻译 你与教授相处得是否融洽对你自身的发展有着巨大的影响，因为这是衡量你是否尊重权威和服从要求的标准。(四) 找出固定搭配，防止分隔现象有时一个长句或难句由一个或多个搭配构成，而且这些搭配中常常出现分隔现象。若受分隔现象的干扰而看不清句子的本来面目，则会对句意的理解产生偏差。Some companies have made the manufacturing of clean and safe products, to some degree, their main selling points and emphasize it in their
