Question

求高手帮忙分析句型！！

And you would think your last name actually being foster. You'd be somewhat equipped to be a foster parent. 特别是句中would的用法和意思，谢谢！

Answer 1

would 是情态动词，在此代替 will 语气委婉。
因为说话人或作者在表示 you 在某种情形下就会有的想法，但will 则很肯定，或者说有些武断，让人听了不舒服。
And you would think... 你就会这么认为……
And you will think...你一定会这么认为……（那也不一定啊！）
