A boy's life was changed by WHO
There is a boy called Karim from Kenya. His life used to be really hard. He was very poor, often got ill, and he even had no chance to go to school. He felt upset and sad all the time.
Later, a worker from WHO went to his town. Karim got free medical checks and treatments with the worker's help. His health condition got better step by step.
Now Karim goes to school every day. He is healthy and full of energy at school. He says he learns that small warm help can make a big difference to a person's life. His dream is to work for WHO when he grows up, so that he can give a hand to more poor people who are in trouble just like him before.

本题为提纲类英语记叙文写作，对应译林版八年级下册国际慈善组织相关单元知识点，写作完成思路如下：
1. 审题：明确写作主题为介绍肯尼亚男孩Karim受WHO帮扶改变人生的经历，以第三人称为主，混合使用一般过去时描述过往经历、一般现在时描述当下状态，适当使用将来时表述个人梦想。
2. 要点梳理：完整覆盖表格全部信息：人物身份、过去贫困患病失学的处境、WHO工作人员提供免费体检和治疗的帮扶、如今健康上学的状态，最后补充他对帮助的理解和个人梦想，保证逻辑连贯，字数符合要求，无语法错误。
