練習(xí)步驟：

第1步手寫：用鉛筆手寫。不需要嚴(yán)格控制時(shí)間，主要是追求質(zhì)量（基礎(chǔ)好的同學(xué)可以自己寫?；A(chǔ)不好的同學(xué)可以看寫作提示，有些寫作提示比較詳細(xì)，有些寫作提示比較簡(jiǎn)單，根據(jù)寫作提示練習(xí)思路擴(kuò)展）。

第2步自查：對(duì)照版本的參考答案自查，自己修訂錯(cuò)誤；

第3步復(fù)盤：重新寫一遍，仍然要求手寫。（最好是等兩天之后再做第3步，因?yàn)楫?dāng)時(shí)馬上寫的話，容易變成背誦），寫完之后再對(duì)照原文。

自己寫過的文章一定要多復(fù)習(xí)幾遍，因?yàn)榭荚嚨臅r(shí)候你一定會(huì)去寫自己最熟悉的詞匯和句子。

練習(xí)的時(shí)候不需要和原文寫得一樣，主要是從原文中學(xué)習(xí)好的詞匯表達(dá)和句式。避免低級(jí)的語(yǔ)法錯(cuò)誤。如果有不理解的語(yǔ)法或者詞匯問題，可以在群里提問，或者戳。
