We've lived here for ten years.我们在这儿已经住了十年了。
2）在不用时间状语的情况下，现在完成进行时表示动作仍在进行。而现在完成时则表示动作在过去已结束。如：
The students have been preparing for the exam.（还在进行）学生们一直在准备考试。
The students have prepared for the exam.（已经结束）学生们为考试作了准备。
3）有些表示状态，感情，感觉的动词如：have，exist，like，hate，hear，know，sound等
动词不能用于现在完成进行时，但可用于现在完成时。如：
They've known each other since 1970.自从1970年起他们就相互认识了。
