句子里的 its 作何解？这边可以省略 it 吗？
Jameson Slattery, vice president of Global Marketing atColor Science, knows what it’s like to be faced with an overflowing inbox every day.
it是形式主语，to be faced with...是不定式作真的主语。因此it不可省略。
what is sth like?中，like是介词，what是介宾，介词短语作表语。名词性从句不倒装，则为what sth is like. 假如不定式作主语，则需要用形式主语it：what it is like to do sth.本句中，what从句是knows的宾语从句。
基本句型：
What is the weather like in your hometown?
