精讲点拨have/hasgoneto

与have/hasbeento的区别havegoneto表示某人“已经去某地了”，说话时此人可能在路上或已到那里，反正不在这里。如：—WhereisJim？吉姆在哪里？—HehasgonetoEngland.他去英国了。（尚未回来）Mr.Wangisn'there．HehasgonetoQingdao.王先生不在这里。他去青岛了。havebeento意为“曾经去过某地”，现在已不在那里了，后可接次数，如once，twice，threetimes等，表示“去过某地几次”，也可和just，never，ever等连用。如：MyfatherhasbeentoBeijingtwice.我父亲去过北京两次。IhaveneverbeentotheGreatWall.我从未去过长城。
