　　 2022考研英语重难点句型解析：名词性从句

　　对于考研英语重难点的长难句的学习，在熟练掌握常见的语法知识的基础上，考研语法侧重在具备充分语境的情况下，有意义地去解析完形填空、阅读理解、翻译等各类题型中出现的长句、难句和某些罕见的语法现象。

　　名词性从句

　　【难句】1. The console can determine how the controller is moving in space and what it is pointing at, and uses that information to control what is happening on screen. (The Economist Dec. 2, 2006)

　　【结构分析】以逗号后and为切入点，得到主句部分的并列平行结构The console can determine…, and uses that information to control…，uses与can determine一起作该句的谓语。其中determine的宾语也以and切入，得到how引导的名词性从句how the controller is moving in space和what引导的名词性从句what it is pointing at(how在从句中作状语，what在从句中作宾语)在use的宾语补足语to control…中，control的宾语使用了what引导的名词性从句what is happening on screen充当，what在从句中作主语。

　　【参考译文】游戏机能测出手柄的移动轨迹，识别手柄指着屏幕上的什么东西，然后根据得到的信息控制屏幕上的游戏。

　　【难句】2. If left unchanged, it appears that the time to cash in on digital sales via services like iTunes is starting to evaporate, especially if the music is set to start leaking into the public domain in the country where it was originally produced. (Business Week Feb. 5, 2007)

　　【结构分析】本句主干为主系表结构，注意appear在这里是系动词用法。表语部分由that引导的名词性从句that the time…is starting to evaporate…充当，不定式短语to cash in on digital sales via services like iTunes 作后置定语修饰the time。especially直到句末是条件状语从句，使用了被动语态 if the music is set to…句末关系副词where引导的定语从句where it was originally produced修饰先行词the country，关系副词在从句中作状语，相当于in which。句首部分If left unchanged，我们可以理解为是分词结构作的条件状语，注意这里使用了leave sth.+adj。用法。

　　【参考译文】如果不改变，则经过诸如iTunes利用数字销售赚钱的时代可能开始消亡了，尤其是当音乐在其初发表的国家已经进入公共领域时。

　　【难句】3. If I ever had any doubts about how demanding a teacher’s job is, it would have disappeared for good when I spent some time recently in schools. (The Guardian Sep. 12, 2007)

　　【结构分析】 本句的结构清晰，为主从复合句。it would have disappeared for good when I spent some time recently in schools为主句部分，其中包含一个when引导的时间状语从句when I spent some time recently in schools。If引导的条件状语从句中，had any doubts about后的宾语由how引导的名词性从句how demanding a teacher’s job is充当，how与形容词demanding相连作从句的表语。注意整个句子使用了与过去相反的虚拟语气，从句为if+had done，主句为would/could/should/might+have done的形式。

　　【参考译文】 如果说我以前还曾怀疑教师的工作有多吃力，那么当我近在学校中待了一段时间后，我永远改变了原来的想法。

　　【难句】4. The teachers who took part in the program also told me of their worries that they might be force-feeding their pupils information rather than stimulating the discussion necessary to ensure they grasped the importance to them of what they were being taught. (The Guardian Sep. 12, 2007)

　　【结构分析】本句成分复杂。主语The teachers 后跟who引导的定语从句who took part in the program also told me of their worries…作修饰语，关系代词who在从句中作主语。told后我们可以认为是双宾语(对象+内容)，直接宾语部分their worries后跟that引导的名词性从句that they might be force?feeding their pupils information rather than stimulating the discussion necessary to ensure…说明worries的具体内容。ensure后面的宾语是一个省略了引导词that的宾语从句they grasped the importance to them of…，grasped的宾语the importance of…被不定式结构to them分隔，of构成的介宾短语的宾语由what引导的名词性从句充当，且从句使用了被动语态的现在进行时。

　　【参考译文】参与节目的老师们还告诉我，他们担心自己可能是在向学生强行灌输知识与信息，而不是激励他们讨论，以此保证他们能掌握他们所学知识的要领。
