frustrated as a new member here, i don't know how to make make use of this website. those days ,i tried some comunication software(in order to improve my oral english),but that makes little benefit to me.i said hello to several people friendly, but their attitude were indiffrent. this makes me frustrated! here, i hope to make acquaintance with someone and help to study language each other! so, nancy, go on, the rode to knowledge is not always flat.best wishes,to me and to the fellows!
