would think与would have thought的区别
would think 和 would have thought 都属于虚拟语气结构，从意思上看，前者表示“会想到”，后者表示“（谁）会想到”。请老师具体谈谈它们俩的区别，谢谢！

你问的可能是二者单独使用表虚拟的用法：
▲would think本身表虚拟时，意思为【会认为，想到】：
Anyone would think you were in love with the girl. 谁都会认为你是爱上了这个姑娘。
Anyone would think he owns the place, the way he talks. 听他这样谈话谁都会认为他是这里的老板。
▲would have thought本身也是虚拟语气，表示【谁会想到，或原本会以为】：
Who would have thought to see you here? 谁会想到在这里碰到你？
Who would have thought of such a thing? 谁会想到这样的事？
Who would have thought she'd end up dancing for a living? 谁会想到她最后落得靠跳舞谋生？
▲通过例句可知。前者具【肯定之意】，人人都会如此认为，其中的 anyone 可换为 everybody；而后者具【否定之意】，没有人会想到。Who一律可换成 nobody。

I should (或 would )think 意思是“我想”、“我估计”，而 should (或 would) have thought 则意为“我会认为”。例如：
I should think we'll be finished by the end of the week. 我估计到本周末我们会完成。
Is she only thirty-five? I would have thought she was much older. 她才35岁？我原以为她还不止呢！
Who would have thought 意思是“谁会想到 ......”。例如：
Who would have thought to see you here !谁会想到在这里遇见你！
（以上均为《薄冰英语惯用法词典》的原文 , p.1159）
你说的这种情况在您的另一个问题中有所体现，如果单纯的说would think，意义就很多了，一是我在另一回答中的表示将来的“可能性”，另外，would可以表示：对过去的可能性的推测；过去常常发生的事情；对一般现在时和将来时的虚拟；would还有“意愿”的含义等等。
would have thought可以表达对过去的虚拟。
所以说，最好是给出具体的例句进行区别。这样提问至少对于would + v.来说涉及太广。
