foralongtime.四.使用现在完成时应注意的几点：1.have(has)beento表示“曾经去过或到过某地”，表示一种经历，现在可能还在那里，也可能不在那里了。它可以与ever,never,once,twice等连用。1.IhavebeentoAustraliathreetimes.

2.Shehashadthebikeforoverayear.

(误)Hehasarrivedhereforthreedays.

(正)Hehasbeenhereforthreedays.

使用“Itis/ithasbeen+时间+since+过去时态的句子”结构或(时间＋have/has+passed+since+过去时态的句子”结构表示以since引导的时间状语从句中的动作自发生以来已经有一段时间了。It后面的be动词常用一般现在时，但有时也可以用一般将来时或一般现在时。1.Itisalongtimesincetheysaweachotherlast.
