For example, an estimate would be appropriate if you're having a casual birthday party and want to know roughly how many bags of chips you should buy.
请问老师:
1 an estimate would be appropriate这里主句是虚拟语气吗?
2 有这样的吗?主句虚拟语气,if条件句陈述语气

【答】主句中的 would be 不是虚拟语气,而是情态动词would表示推测的用法。条件状语从句中的现在进行时表示“打算”、“准备”、“计划”做某事; and 后面的动词 want 表示“想要”的意思,不能用进行时,所以用一般现在时。
