读后续写写作攻略
读后续写中读的过程要做到找、划、猜。找文章的主题，划出表现人物性格/推动情节发展的词句，猜测故事的内容走向。
下面我们以沈阳市二模为例演示写作过程。
1.找主题 Theme: kindness from strangers
2.编内容
Para 1 接到电话后担心紧张；打手机询问打不通；决定转钱
Para 2 紧张被店员注意；店员报警真相大白；感激/升华
3.分配细节
Para 1 担心紧张的心理/表情描写；决定转钱时的连动
Para 2 两人对话的语言描写 ；得知真相后的心理描写
4.写草稿
Para 1 Cecil was totally at a loss. Astonished and suspicious, he called David's mobile phone to see what happened. However, the line was busy, which made him more anxious. Worrying about his grandson, he found his credit card and set off for Walmart.
Para 2 The lucky part of Cecil's day was when he stepped into cashier Audrella's line in Wal-Mart. "How can I help you?" she asked gently. "I need to transfer $2300 to another store."said Cecil nervously. Sensing his nervousness, Audrella asked if everything was okay. After Cecil told her the whole story, Audrella called the police. When two officers arrived, Cecil were calm again and realized that the whole thing was a phone scam. Cecil held Audrella's hands, and thanked her sincerely for her kindness and love.

However, after calling up to 10 times, the line was busy all along, which only added to his anxiety all the more.

Para 2 The lucky part of Cecil's day was when he stepped into cashier Audrella's line in Wal-Mart. "How can I help you?" she asked gently. "I...I need to transfer $2300 to...to another...store." stammered Cecil, sweat rolling down his forehead. Sensing his nervousness, Audrella couldn't help asking if everything was okay. With a shaking voice and reddened eyes, Cecil told her the whole story, pinning all his hopes on this young girl he'd never met before. Burning with mounting suspicion, Audrella called the police. With the arrival of two officers, Cecil regained his calm and came to the realization that the whole thing turned out to be nothing but a phone scam. Holding Audrella's hands tightly, Cecil couldn't thank her enough and gave her $100 in reward, knowing too well that no price was too high for the random act of kindness and love.
