to do sth.这是常见的不定式后跟动词原形,表即将发生、未发生的事情.
若表达已经发生的事情,用
to have done sth.结构
题中,当我们到达那里时,他们碰巧已经离开去天津.
我们到时,他们已经离开,离开的动作在我们到达时就完成,故用
to have left 结构,选B
希望能满意,欢迎进步!:)
强调过去的过去,已经去了
have+过去式表示已经离开开
当我们到达那里是,他们碰巧已经离开了
happen的用法如下
happen to do sth 表恰巧做某事
happen to have done sth 表恰巧已经做过某事
happen to be doing sth 表恰巧正在做某事
