For this part, you are allowed 30 minutes to write a letter to express your thanks to one of your friends who helped you most when you were difficulty. You should write at least 120 words but no more than 180 words.

通过题干我们可以分析出，针对感谢信的写作要求，我们应该注意以下几点：

1. 格式要正确。与其他应用文写作一样，书信体裁需要在正文的前面加上称呼，在正文的末尾加上结束语，落款和署名。

2. 标点符号要正确。Dear+称谓的后面一定要用逗号，不能用冒号。还要注意英语的句号是实心的，并且涉及到书名、电影名或者作品名的，要大些，英语中没有书名号。

3. 考生需要根据题目要求完成写作。在这一部分，考生需要注意字数的要求是120-180字，不能少些或者超出。另外，虽然题目中并未对落款人作过多要求，但是考生还是有必要把敏感的人名、地名和学校名去掉，以防作弊嫌疑。

4. 通过三个题目的要求，我们都要明确表明我们的感激之心，表述时要目标明确，语言贴切、充分，内容言之有物，句子流畅地道。
