这两个句子一样吗?有什么区别

(1)不定式作表语一般表示具体动作,特别是表示将来的动作。 A.不定式作表语。 例如 :To do two things at a time is to do neither.一次做两件事等于未做。 What I would suggest is to start work at once.我的建议是立刻开始干。 B.如果主语是不定式(表示条件),表语也是不定式(表示结果)。 例如:To see is to believe.百闻不如一见。 To work means to earn a living.工作就是为了生活。 C.如果主语是im,duty,hope,idea,happiness,job,plan,problem,purpose,thing,wish等为中心的名词,或以what引导的名词性从句,不定式作表语是对主语起补充说明作用。 例如:His wish is to buy a luxurious car in the near future.他的希望是在不远的将来买一辆豪华轿车。 (2)动名词作表语:表示抽象的一般性的行为。 例如:Our work is serving the people.我们的工作是为人民服务。 His hobby is collecting stamps.他的爱好是集邮

Her job was looking after the sick boy.
Her job was to look after the sick boy.
这两个句子有一点区别.第一句动名词做表语是表示动作的一惯性.第二句表示动作的一次性,且将来的动作.所以第一句意思是:她的工作是一直照顾这个生病的孩子.第二句是:她的工作是要照顾这个生病的孩子.
