Mother saved every cent she could spare to pay for my schooling.
这里she could sapre是定语从句,省略了引导词that.去掉定语从句,句子就变成了Mother saved every cent to pay for my schooling.妈妈攒钱支付我的学费。支付学费是攒钱的目的,目的状语用动词不定式。
2. there be 句型的变形,一般情况下,介词后面宾语应该用 there being。而for后面用there to be这是一个固定用法,没啥好说的。答案解析给的不是很恰当,因为介词宾语后面主要是there being.
追问谢谢你,好详细呀!
