定从的特殊用法: 🟠只能用 that引导词: 🔺先行词有人有物时; 🔺先行词被最高级，序数词，the only, the very(正是)修饰时; 🔺先行词是all，anything, everything, nothing, none, much, little, few，many等不定代词或被它们修饰时 🟠非限制性定语从句只能用which 🟠先行词是situation，case,occasion, point等抽象地点，常用where引导 🟠先行词和引导词之间有介词，用which(物)或whom(人) 🔺介词 +which/whom 这个一定要会!这部分我也是做题容易纠结，主要是动词搭配的介词需要积累! 🟠whose特殊用法 🔺名词1+whose+名词2 The boy whos expression is very rich called Xiao Ming 🔺whose+名词2=the+名词2+of+which/ whom He lives in the house the window ofwhich opens to the south. 🟠as(正如，好像) 🔺限制性定从:先行词被such或the same修饰时用 as 🔺非限制性定从:As we all knows ,/As is known to all, /As is often the case 等数量词+of which/whom 🔺the way(.....的方式)作先行词 the way+ in which,that，省略 记住以上特殊用法加上练习题巩固，定语从句拿捏!
