From the first day he entered my classroom, Willard P. Frank existed in his own world, shutting out

One possible version:
Paragraph 1：
On that Sunday, I paid a visit to Willard’s family. On entering his house, I was surprised to find a barely empty room with a broken bed and a dirty sofa. Willard told me his mother died and that his father was missing, leaving him to live with a sick grandma. When asked why he had given the two quarters, Willard mumbled, “I just want to help others by contributing my milk money.” I couldn’t help bursting into tears, thinking I should help him break his silence.
Paragraph 2：
The next day, I had a special class for Willard. I shared his story with the whole class and said, “Now, on behalf of the people in need, I should say thanks to Willard, you are great!” After a silence, all the students clapped, saying “Willard, you are great!” and they walked to him and hugged him tightly. A friend relationship was built and Willard’s silence was broken by a smile on his face.
【解析】
本篇书面表达是读后续写。通过阅读所给文章可知，沉默寡言的Willard同学，在感恩节其他同学都忘记带要捐赠的东西时，Willard毅然决然捐出了自己的牛奶费用。作者随后在贫困生名单中发现Willard赫然在列，所以决定帮助Willard。
续写部分分为两段，第一段开头是：星期天我前往Willard家进行家访。上文讲到Willard时贫困家庭，所以这一段落的续写应该是围绕着Willard家有多么贫困所展开。所以应该具体写家中的装潢来体现贫困。第二段的开头：接下来的一天，我决定给Willard一场特别的课。上文说到虽然贫困，但是Willard还是捐出了自己的牛奶钱。所以这一段肯定是要通过这堂课对Willard的奉献精神进行赞扬，以及课堂结束后所带来的结果。
续写时要求使用文章中的关键词，所以这就增加了写作难度，我们要熟悉文章的主要大意以及关键词，恰当的时候加以运用。最后还要注意所续写短文的词数应为150左右。按要求完成写作任务。
【点睛】
本文描写详略得当，使用了高级词汇和高级句子。如：can’t help doing; burst into tears; mumble等高级词汇；宾语从句和状语从句的省略When asked why he had given the two quarters, Willard mumbled, “I just want to help others by contributing my milk money.”展示了句式的多样性；而非谓语作状语I couldn’t help bursting into tears, thinking I should help him break his silence.更是写得好；通过这些高级句型，让这篇文章增色不少。
