謂語變被動（時態(tài)不變）

be+being+done+by3.主動語態(tài)變被動語態(tài)的原則“三變”例：Theyarebuildingnineparks.原句主語變?yōu)閎y短語賓語變?yōu)橹髡Z謂語由主動變?yōu)楸粍印叭蛔儭痹湟馑疾蛔冊鋾r態(tài)不變原句主謂賓以外成分不變Nineparks______________bythem.Howmanyparks____________?arebeingbuiltarebeingbuilt三、現(xiàn)在進行時的被動語態(tài)的用法1．表示此刻正被進行的動作，句中常用now，atthemoment等時間狀語。Changjinhu

isbeingshowninthecinemanow.Let'sgotoseeit.現(xiàn)在《長津湖》正在電影院放映呢，咱們?nèi)タ窗伞?．表示現(xiàn)階段正被進行的動作，但此動作在此時此刻不一定正在發(fā)生?！狢ouldIuseyourcarplease?—Mineisbeingrepairedbytheworkers.——我能用你的車嗎？——我的車正在被工人們修著。3．表示一種經(jīng)常性的被動行為，常和always，constantly，frequently等表示頻率的副詞連用，這種用法常常帶有說話者的贊揚或厭惡的感情色彩。Ifeelverypuzzledthatthegoodsinourshoparealwaysbeingstolen.我感到很迷惑，我們商店的商品老是被偷。4．表示按計劃或安排主語將要承受謂語動詞所表示的動作。Awelcomepartyisbeingheldtonight.今晚將要舉行一場歡迎晚會。5．與部分情態(tài)動詞連用，表示對正在發(fā)生的動作的推測。Hemaybebeingscoldedbyhismoherattheverymoment.此刻他也許正被他媽媽責罵呢。isbeingdiscussedbeingpraisedisbeingmade13四、使用現(xiàn)在進行時的被動語態(tài)應注意的問題1．不可遺漏being現(xiàn)在進行時的被動語態(tài)中，be為第一助動詞，being為第二助動詞，缺一不可，且位置不可互換。此結(jié)構若缺少being，則就成為一般現(xiàn)在時的被動語態(tài)或系表結(jié)構。試比較：Thereportisbeingwrittenbyafamousprofessor.報告正在由一名著名的專家寫著。Thereportiswellwritten.這個報告寫得很好。(系表結(jié)構)2．不可遺漏介詞takecareof，lookafter，talkabout，thinkof等動詞短語用于現(xiàn)在進行時的被動語態(tài)時，其中的介詞不可省略。Look！Thechildrenarebeingtakencareofbytheirgrandmother.瞧！那些孩子正由他們的奶奶照看著。3.沒有進行時的被動語態(tài)一些表示狀態(tài)、心理活動、擁有、存在等的動詞(和主動語態(tài)一樣)一般不用進行時被動語態(tài),常用一般現(xiàn)在時被動語態(tài)表示此時此刻或目前主語承受謂語動詞的動作。

3．“be(am/is/are)＋under/in＋n.”
