1、2022年高三英語一輪復習 虛擬語氣導學案 虛擬語氣一直是英語語法的難點之一。由于英漢差異以及中外各語法家對虛擬的不同論述,學生們對這一語法現(xiàn)象經(jīng)常存有疑惑,學習起來比較困難。 為了有效促進虛擬教學,幫助學生掌握虛擬語氣,首先統(tǒng)計出兩組學生在各個具體虛擬語法結(jié)構(gòu)中的總體出錯情況,然后比較了兩組學生在他們都犯錯較多的幾個虛擬結(jié)構(gòu)中的出錯狀況。最后依據(jù)三大錯誤類型(語際錯誤,語內(nèi)錯誤和特殊錯誤)對錯誤原因做了詳細的討論。研究結(jié)果顯示學生們比較容易犯語內(nèi)錯誤,且他們的出錯情況和英語水平無關(guān)。通過進一步分析,把語內(nèi)錯誤再細分為過度泛化性,規(guī)則非完整應用,概念假設和虛擬規(guī)則判斷錯誤,并對這些細分的錯誤

2、類型做了具體的示例解釋。為了幫助學生有效應對這些錯誤,采用測試卷中學生的錯題為例,針對三大錯誤類型,提出了具體的應對方法。 最后得出了教學啟示,希望教師能重視虛擬問題并提高自身教學能力,幫助學生提高虛擬應用和交際能力。 Teaching aims: 1. Review the different forms of subjunctive mood 2. the use of subjunctive mood of if clause Difficult points: the use of subjunctive mood of if clause Ste
