【英语】英语长难句解析之名词性从句

发布时间:2016-06-05 14:33:07    作者:深圳华章    阅读次数:2385

导言:

昨天咱们分析解决了定语从句这个大难题,想必大家已经大有收获,今天就进入另一大难点名词性从句的分析。


名词性从句  

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,uses与can determine一起作该句的谓语。

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

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。  

【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。  

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,则通过诸如iTunes利用数字销售赚钱的时代可能开始消亡了,尤其是当音乐在其最初发表的国家已经进入公共领域时。  

3. The trouble with that approach is that consumers tend to prefer devices that require simply plugging them in, without complicated setups of wireless channels, security, and other features common to home networks. (Business Week Jan. 29, 2007)  

【结构分析】 本句主干很清晰,是主系表结构。

其中表语部分由that引导的名词性从句that consumers tend to prefer devices…充当。

device后是that引导的定语从句 that require simply plugging them in…,关系代词that在从句中作主语。

逗号后的介词短语 without complicated setups of wireless channels, security, and other features…作从句中的伴随状语(在翻译时我们可以转译为定语).

句末的形容词结构common to home networks后置作features的定语。  

【参考译文】 这一方式的问题在于,消费者更喜欢不需要创立复杂的无线电频道、安全保护以及家庭网络所共有的其他特性,便可以简单插入的装置。  

4. In its 16 years of operation it has found the first convincing evidence for the existence of black holes, made observations supporting the theory that the universe’s expansion is accelerating and confirmed that dark matter exists. (The Economist Nov. 2, 2006)  

【结构分析】

去掉句首介宾In its 16 years of operation作的时间状语,以and为切入点,得到主句it has found…, made…and confirmed…

其中made后的宾语中,包含现在分词结构supporting the theory…作的伴随状语,在此伴随状语中,that引导同位语从句that the universe’s expansion is accelerating解释说明theory的内容;

而confirmed后的宾语由that引导的名词性从句that dark matter exists充当。  

【参考译文】在它运行的16年中,首次发现了关于黑洞的令人信服的证据,很多观测都支持宇宙加速膨胀的理论并确认暗物质的存在。
