题目分析：考查半开放性作文的写作。文字提示中只给出了部分的要点，考生可以在生活上的照顾和学习上的帮助展开说明，其中具体的做法，和你的感激之情。.写作时注意准确运用时态，上下文意思连贯，符合逻辑关系，尽量使用自己熟悉的单词句式，同时也要注意使用高级词汇和高级句型使文章显得更有档次。特别注意在选择句式时要赋予变化。
点评：首先认真审题，并在脑海中回想自己积累的哪些句式、句型、单词能用进来，这些单词、句型都应是经典的，不会错的。写的过程中，多注意灵活使用定语从句，包括非限制性定语从句。要熟悉英美人写文章的习惯，遇到专有地名、人名一定要用非限制性定语从句，强调唯一性。平时的英语作文就可以多尝试使用这些表达，考试时才能游刃有余，胸有成竹。
