air-conditional,air-conditioned的区别？
如果要说某个地方已经用了空调，用air-conditioned，比如an air-conditioned room(开了空调的房间)；如果是形容某样东西有空调功能或单讲空调功能，则用air-conditional，比如air-conditional system（空调系统）。
收到conditional offer怎么办？
这是条件录取的offer，不是最终offer。首先你得回复邮件accept，不然过几个月会被取消资格。你可以同时确认接受多个XX的offer，不会发生任何成本。有的XX在conditional offer里面可能还会提及押金，这个一般入学前4、5个月的时候就得交，在交的时候就得考虑好选择去哪个XX了，不然押金可能就没来，当然钱多可以多交几个XX……
然后看还需要满足什么条件，一般是雅思成绩、本科成绩单和毕业证以及学位证（这仨需要原件和有资质的翻译件），来换取最终的unconditional offer，这才能确定能上学。雅思分不够的可以考虑读个几周的语言课或者1年点预科。
第一条件句到第三条件句的规则？
注意：If 引导的一般从句和第一条件句较容易理解.
第二和第三条件句都是虚拟语气,不同的是,第三条件句是表达和过去相反的条件句.
常见第二条件句的例子就是,If I were you, I would.
常见第三条件句的例子就是,If I had done, I would have.
