英语语法问题。

这里的“who they friend on Facebook”怎么理解？求句子语法详解。

Using data to decide someone’s eligibility for a line of credit or health insurance, or even recommending who they friend on Facebook, can affect their lives.

Answer 1

would have been 通常用在虚拟语态中，表示将会做与过去事实相反的动作。would have been中been是be的过去分词。例：Had I not suspended three years ago, I would have been a bachelor already.要不是我三年前辍学了，我现在早就拿到学士学位了。 If I had studied hard,My English would have been well.如果我之前努力学英语，我的英语现在会很好。
