段首句作文要求习作者按所给每个段落的第一句续写，完成该段落，并注意紧扣主题，尽量表达原作者所要表达的思想，写出与段首句在意义上连成一体，形式上互为统一，语气上一气呵成的文章。

1. 写作技巧

1) 认真审查标题

短文的标题是对全文的高度概括。如果习作者能在清理思路、确立文章的框架之前，正确把握标题所包含的信息，就会大大减少写作中偏离主题的情况。

2) 认真分析各段首句包含的信息，找出每个段首句包含的关键词或词组。切忌找错关键词或词组，偏离主题。

3) 把握好段首句与标题的关系

英语词汇的含义比较多，如果标题里或主题句中某个关键词有多种含义，而习作者对其含义又吃不准时，可以通过主题句或标题的含义来帮助习作者对词义进行准确选择，以达到切题的目的。

4) 弄清段首句是主题句还是一般的提示句。有些作文试题，尤其是当作文属记叙文时，各段给出的句子不一定是阐明段落中心思想的主题句，而只是文章的一段开场白，或称提示句（或词），它引出文章结构的思路，习作者只需按照这些提示

句（词）提供的思路去描写就行了。

5) 仔细斟酌各段首句之间的相互关系，以获得对整篇文章的印象，明确文章主题思想展开的趋势。

6) 考虑好续写的方式或模式，拟定提纲。

7) 续写的句子必须有较强的说服力，能起到支持和说明段落中心的作用。

8) 句子之间、段落之间过渡要自然，前后要照应。
