定義：現(xiàn)在完成時的動作或情況雖然發(fā)生在過去，但它強調(diào)的是與現(xiàn)在的關(guān)系，用來說明現(xiàn)在的情況。現(xiàn)在完成時態(tài)結(jié)構(gòu)：(have/has+過去分詞)現(xiàn)在完成時態(tài)TheprogrammehasbeenbroadcastedsinceNovember.思Thefivechildrenhavebeeneducatedthroughthegame.Thefivefamilieshavebeentalkedaboutalotnowadays.Lead-inTheirphotoshavebeenmadefunofbythenetizens.現(xiàn)在完成時被動態(tài)結(jié)構(gòu)：

（3）一些特殊動詞,如borrow,finish,begin,buy,start,return,marry,open,join等構(gòu)成的現(xiàn)在完成時的被動語態(tài)不能與表示一段時間的狀語連用。若要表達相應的意思，則需改換動詞或時態(tài)。
