定语从句用来修饰名词。名词可以充当主语,表语,宾语等成分。所以,我们在这些句子成分后加上一个定语从句,就可以实现从简单句到复合句的升级。 1. We all know the person. 这句话中,宾语是the person,是名词。我们可以在后面加上定语从句,修饰the person,使句子变成一个含有定语从句的主从复合句。We all know the person who donated money to the local school.我们把这个定语从句进行拆分,可以拆分成两个同时含有先行词the person的句子。① We all know the person.② The person donated money to the local school.我们会发现,在句子②中,the person 作句子的主语,和donated是主动关系,所以,定语从句可以改成现在分词作后置定语,现在分词表示和被修饰名词之间是主动关系:We all know the person donating money to the local school.2. Anyone should be punished.这句话中,主语是anyone,是名词。我们可以在后面加上定语从句,修饰anyone,使句子变成一个含有定语从句的主从复合句。Anyone who breaks the rules should be punished.我们把这个定语从句进行拆分,可以拆分成两个同时含有先行词anyone的句子。① Anyone should be punished.② Anyone breaks the rules.我们会发现,在句子②中,Anyone作句子的主语,和breaks是主动关系,所以,定语从句可以改成现在分词作后置定语,现在分词表示和被修饰名词之间是主动关系:Anyone breaking the rules should be punished.3. This is the lucky girl.这句话中,表语是the luck girl,是名词。我们可以在后面加上定语从句,修饰the luck girl,使句子变成一个含有定语从句的主从复合句。This is the lucky girl who was saved by a hero.我们把这个定语从句进行拆分,可以拆分成两个同时含有先行词the lucky girl的句子。② The luck girl was saved by a hero.我们会发现,在句子②中,the luck girl作主语,和saved是被动关系,所以,定语从句可以改成过去分词作后置定语,过去分词表示和被修饰名词之间是被动关系:This is the lucky girl saved by a hero.
