劃分一下句子成分就容易理解一些了：
I really valued the insights (that they gave me into being on the receiving end of multinational marketing).我添加了that,that 引導(dǎo)的從句做insights的定語.
they gave me into (being on the receiving end of multinational marketing).into在這里是介詞成份,引導(dǎo)后面括號中名詞成份的短句.
be on the end of 是說作為......的終端
這樣劃分后,可以清楚了解句子的含義是：我認(rèn)為他們（所給予我們作為國際市場接收終端）的眼光十分有價(jià)值.
