ight结论一：名词从句充当句子的主要成分；定语从句充当句子的修饰成分。2引导词含义上的区别：引导词是否指向句中的某个成分？1Thathecamebackmadeusveryhappy2I’msorrythatI’vemadeamistake3Thefactisthathisbarkisworsetha

a结论二：定语从句的引导词在语义上具有指代先行词的作用。名词从句的引导词不具备此功能。3关于thatthat在名词从句和定语从句中各起什么作用？1Heprete

where等不能与i
o
atwhich互换。
f不会出现在定语从句中的关系词：whetherifwhathow5、名词从句与定语从句的一些对应关系：1Hehasdo
