四、同位语从句:由两个或两个以上同一层次语言单位组成的结构,其中前项与后项所指相同,句法功能也相同,这种结构叫同位结构。名词词组,反身代词,不定代词或指示代词、ING分词、不定式和从句都可作同位语。用来作同位语的从句叫同位语从句。同位语从句主要由that引导,这时that从句表示它所修饰词的实际内容

五、例题解析
1) D对。句中已出现了谓语动词“is”,这就决定了“is”前面为其主语,如主语中再有动词出现,便成了主语从句。A 不对。因为连续出现了两个动词“is”,且其间又无连接词;B好像是“that”引导的主语从句(下面将提到) ,但由于介词“with”要求带宾语,而B 选项本身又无法解决这个问题(“that”引导的主语从句中,“that”为连词,不可能去充当“with”的宾语) ,故B也应排除;C句的语序有误,因本句并非倒装句(句末为句号),因此没必要倒装;只有D为正确答案。“what”为代词,相当于“the thing which”,这样“what”本身便可充当“with”的宾语。本句的汉语意思为“三角学所涉及的(对象) 是角的测量及角之间的关系”。因此,凡“what”带的从句中,“what”本身一定要充当从句中的成分,或宾语(含介词宾语) ,或主语。
2) B对。本句有两个动词(“has”和“is”),且中间并无等立连词分开,显然本句为一个名词从句作主语的句型,符合此条件的只有B,其中句首的“that”与“what”引导的主语从句的区别在于:“that”在句中不充当任何成分。本句更多的情况下是说成:“It is true that cultural…coherence.”这样就由“it”充当逻辑主语,而真正的主语“that从句”放在了后面。
3) D为正确答案。句首的“it”为逻辑主语,指代后面的“that从句”,本句亦可说成“That any new…fertilized should be taken for granted”。
4) B错。改为“that”,理由见上例。
5) D对。本句汉语意思是“某些哺乳类动物是如何到海中生存的仍是一个迷。”那么A 为什么不对呢?为什么不可理解为是“that”引导的主语从句呢?“that从句”作主语时是陈述性的句子,即为一个事实,因此句子的谓语也应与其呼应,即肯定性的论述;而由疑问代词、副词及whether引导的主语从句都为疑问性的句子,即不是肯定的结论,因此其谓语也应当是否定的或含疑问性质的论述。本句中的谓语为“is not known”(大家不知道) 即属于否定的和含疑问性质的论述,故应选D。
6) B为正确答案。本句的谓语“is widely believed”(被广泛地认可) 为肯定性的论述,因此A和D选项不对。
7) D对。“agree”(同意) 可以后面接“that”引导的宾语从句,但它不可直接跟名词作其宾语,如要接名词,需在名词前加介词“upon”、“on”或“with”。
8) A对。“indicate”(显示) 为及物动词,它后面接了一个以“where”引导的宾语从句。由于本句为陈述句,故D 答案不对。
9) B对。“what grows…”作介词“on”的宾语,其中“what”作从句的主语,相当于the thing which。
10) A对。
11) C对。本句系动词 “is”后需接表语,而C为由“what”引导的从句,可以充当其表语,故C 为正确答案。B 不对。因为“known”无论是形容词还是过去分词都不可再接“what”从句;D 中的“it”多余,因为它占据了从句中主语的位置,这样,从句中既不缺主语,也不缺宾语和表语,于是代词“what”便无所指,故只有C 为唯一正确答案。
12) B对。空白处成分系进一步解释说明句子的主语,位于主语和谓语之间,且前后有逗号隔开,将同位语去掉原句仍完整,其功能相当于一个非限定性定语从句,即“who was a statistician”。
