1、專題一　解題策略 寫好高考“書面表達(dá)”絕非一日之功，關(guān)鍵在于平時(shí)扎扎實(shí)實(shí)的訓(xùn)練。但是，在夯實(shí)語言基本功的前提下，熟悉、掌握一定的應(yīng)試技巧，也非常重要。根據(jù)“書面表達(dá)”常見錯(cuò)誤及評(píng)卷要求，建議使用“一式，兩頭，三寫，四關(guān)”的應(yīng)試搶分技巧。具體為： 一式 寫對(duì)格式 要求記住英語常用文體的格式和應(yīng)用文體的寫作方式和特點(diǎn)。 二頭 寫好兩頭 要求靈活運(yùn)用熟悉的句式和表達(dá)手法，使文章開頭和結(jié)尾結(jié)構(gòu)正確，言簡(jiǎn)意賅。 三寫 規(guī)范三寫 在高考英語書面表達(dá)的評(píng)分標(biāo)準(zhǔn)中，正確拼寫和使用標(biāo)點(diǎn)符號(hào)及書寫的美觀程度也是影響得分的一個(gè)重要指標(biāo)，因此考生要高度重視。許多考生

2、只重視書面表達(dá)內(nèi)容的訓(xùn)練和提高，卻忽視了卷面規(guī)范書寫的訓(xùn)練，導(dǎo)致本不該的失分。 四關(guān) 突破四關(guān) 所謂“四關(guān)”是指突破內(nèi)容要點(diǎn)關(guān)、行文邏輯關(guān)、語法規(guī)則關(guān)和習(xí)慣表達(dá)關(guān)。要求內(nèi)容要點(diǎn)準(zhǔn)確全面，行文邏輯通順嚴(yán)密，語言運(yùn)用正確得當(dāng)，表達(dá)方式符合英語習(xí)慣。 當(dāng)然，在備考過程中，有針對(duì)性地背誦一些高分句式，套用合適的寫作模塊，可以幫助大家在短時(shí)間內(nèi)在書面表達(dá)上搶得高分！ 真題導(dǎo)練 　(2019·全國卷Ⅲ)假定你是李華，你校將舉辦音樂節(jié)。請(qǐng)寫封郵件邀請(qǐng)你的英國朋友Allen參加，內(nèi)容包括： 1．時(shí)間； 2．活動(dòng)安排； 3．歡迎他表演節(jié)目。 注意：1.詞數(shù)100左右； 2．可以適當(dāng)增加
