同位语
1 界说
同位语的界说为两个名词或代词,比较接近,可以作相同的成分,而且第二个名词起到弥补解说阐明第一个名词的作用。比如,Mr. Smith, our new teacher, is
very kind to us。 Mr.Smith和our new teacher这两个名词都可以做主语,our new teacher弥补解说阐明Mr. Smith,所以它便是Mr. Smith的同位语。
在TOEFL & IELTS考试中,同位语并不是许多。而且,第二个单词往往会带有一个比较长的定语从句来弥补解说阐明第一个单词。
例1.
They must also keep swimming to keep fromsinking, since most have largely or completely lost the swim bladder, thegas-filled sac that helps most other fish
remain buoyant.
【解析】
在该句中,the gas-filled sac作the swim bladder的同位语,它们都是名词,而且the gas-filledsac后有一个后置定语从句来修饰。
【答案】
They must also keep swimming to keep fromsinking, since most have largely or completely lost the swim bladder, thegas-filled sac [that helps most other fish
remain buoyant].
例2.
A 2003 Mars Global Surveyor image showswhat mission specialists think may be a delta ― a fan-shaped network ofchannels and sediments where a river
once flowed into a larger body of water,in this case a lake filling a crater in the southern highlands.
【解析】
在该句中,a fan-shaped network of channels andsediments作a delta的同位语,它们都是名词,而且afan-shaped network of channels and sediments后有一个
后置定语从句来修饰。
【答案】
A 2003 Mars Global Surveyor image showswhat mission specialists think may be a delta ― a fan-shaped network ofchannels and sediments [where a river
once flowed into a larger body of water,in this case a lake filling a crater in the southern highlands].
2 同位语从句
同位语难也是首要难在同位语从句上。同位语从句指的是在复合句中充当同位语的从句,属于名词性从句(详见3.2)。只不过这些可以跟同位语从句的名词是
一些特定的抽象名词,news,idea,fact,suggestion等,例如,I heard the news that our team had won。值得注意的是,that衔接从句时从句为一个句意完好
的陈述句。that不能省掉,没有具体的意思,不充当语句成分,只起衔接作用。
处理方法也好像定语从句的处理方法,但后面的从句成分完好,直接把该句分解为I heardthe news和our team had won两个语句即可。
小编找到的是作者的一些见解,希望可以为考生们寻找到最好得分方式,也希望对大家有所帮助。最后,希望广大考生们在备考过程中提升自己的语言水平,取得更好的成绩。
