初中英語虛擬語氣講解及練習(xí)

初中英語虛擬語氣講解及練習(xí)英語中的語氣分為陳述語氣、祈使語氣、虛擬語氣三類。虛擬語氣表示說話人的主觀愿望或假想，所說的是一個條件，不一定是事實，或與事實相反。條件句可分為兩類，一類為真實條件句，一類為非真實條件句。非真實條件句表示的是假設(shè)的或?qū)嶋H可能性不大的情況，故采用虛擬語氣。如果假設(shè)的情況可能發(fā)生，是真實條件句，這種情況下謂語用陳述語氣。如：Iftimepermits,we'llgofishingtogether.如果?時間允許，我們就一起去釣魚。如果假設(shè)的情況是不存在的或不大可能發(fā)生的，則是虛擬條件句。如：Ifyouhadcomeyesterday,youwouldhavemetthatfamousprofessor.如果?你昨天來，你就會見到那位著名的教授了。(隱含的事實是：你昨天沒來，也沒見到那位著名教授)。虛擬語氣的基本形式和用法在含有虛擬條件句的復(fù)合句中，主從句的謂語都要用虛擬語氣。.含有條件狀語從句的復(fù)合句wish(wouldrather)+賓語從句suggest(…)+賓語從句.主語從句Itis+adj./p.p/n.+that+S+(shou⑹+do表語從句S+isthat+s+(should)+do同位語從句S+that+s+(should)+do.定語從句Itis(high)timethat+S+did用過去式表現(xiàn)在情況.時態(tài)后退型用過去完成式表過去兩種形式 用過去將來表將來.should+動詞原形型內(nèi)容詳述.含有條件狀語從句的復(fù)合句(以do為例5=主語)時間條件狀語從句主句與現(xiàn)在事實相反的假設(shè)If+S+did… S+would/should/could/might+d?！c過去事實相反的假設(shè)If+S+haddone…S+would/should/could/might+havedone…與將來事實相反的假設(shè) did…If+SshoulddoweretodoS+would/should/could/might+d?！⒁馐马棧?、倒裝句。如果1條件句中含有功能詞had,should,were時，可以省去用把功能詞提前，構(gòu)成倒裝句。2、錯綜條件句。若條件句和主句動作不存在同一個時間，則謂語形式應(yīng)根據(jù)具體情況而定。3、Ifthereweren't/hadnotbeen+???=without…4、Ifitwerenotfor…/Ifithadn'tbeenfor-=butfor…5、otherwise+虛擬語氣的句子6、虛擬語氣的句子，but+陳述事實的句子.虛擬語氣用在賓語從句中sb.did…（希望現(xiàn)在用過去式）wish+thatsb.haddone…（希望過去用過去完成灰）sb.would/shoulddo（希望將來用過去將來）wouldrather后的從句要用虛擬語氣。時間從句虛擬現(xiàn)在
