Great! Ive been longing to visit the exhibition on the western artists .2. as I know, everybody wants to be a model student.3. Great changes have taken place in our hometown. 4. Ive never met him.5. Things have not change very much .三情景解疑現(xiàn)在完成時1. 構成：has / had + 動詞的過去分詞2. 基本用法： 表示過去發(fā)生或已經(jīng)完成的動作對現(xiàn)在造成的影響和結果?？梢员硎咀罱瓿傻膭幼?，也可以表示經(jīng)歷或經(jīng)驗。表示過去已經(jīng)開始、持續(xù)到現(xiàn)在（可能還會繼續(xù)進行下去）的動作或狀態(tài)，常和表示一段時間的狀語連用。3. 時間狀語：just, recently, so far, up to now, till now, in the past, ever, never, for, since, these days, this year, now等。4. 短暫性動詞和延續(xù)性動詞： 短暫性動詞用于完成時態(tài)時，不表示延續(xù)概念，不能跟表示一段時間的狀語連用，需要時要用相應的延續(xù)性動詞替換。常見的有：buy have, borrow keep, leave be away, die be dead, return be back, put on wear, catch a cold have a cold, fall asleep be asleep【例】 Since two years ago.A. How long have you joined Greener China?B. How long did you join Greener China?C. When did you join Greener China?D. How long have you been with Greener China? 解析：Since two years ago.表示的是時間段，因此問話問的應該是多長時間，答案在A，B和D之間選。由于動詞join是短暫性動詞，無延續(xù)性，不能與表示一段時間的狀語連用，故選D。四合作探究【思考】讀下列例句，說說一般過去時和現(xiàn)在完成時的區(qū)別是什么？ The light has gone out.
