第一个句子是动词不定式作表语,第二个句子是动名词作表语.
只要是to+动词原形就是动名词短语,只要是动词的ing形式就是动名词(用在进行时中的称为现在分词),to do 或者doing这里的do如果是及物动词,那么直接跟着宾语,如果是不及物动词,那么会加个介词,然后加宾语.只要符合这样的形式,那么就是分别是不定式短语和动名词短语了.
因为to look after the baby 和taking care of the patient 在句子中作的成分都为表语,是名词性成分。动词不定式短语,动名词短语是名词性成分,相当于名词。
而介词短语(to)或 现在分词(ing)不是名词性成分,不具有名词的作用。
希望帮到你~
Is为系动词, 后接成分为表语,解释His job.Taking 如果是现在分词,不可能做表语.
