5、齐全。3地道成句。将所列要点用完整地道的英语句子表达出来。4连句成篇。在连句成篇时，同学们首先要理清句子之间的关系，选用适当的表示并列、递进、转折、因果、条件、时间顺序等意义的连词或词组，把有关要点或句子连接成文。其次，要避免句子结构的单调重复。最重要的是，如果发现上下句之间跳跃性太大，没有逻辑关系时，要根据自己的生活经验，适当发挥想象，增加合理细节，使文段衔接自然，行文流畅。5查漏勘误。在草稿上写好全文后，同学们要通读全文，查漏勘误。主要注意以下三点：(1)查人称、体裁、动词形式是否正确。(2)查句式，看句子结构是否完整，语序是否正确，习语搭配是否无误，短文中是否使用了一到两个结构较为复杂的

6、句子。(3)查句子数或字数是否符合要求。6规范誊写。书面表达是主观题，给分标准有主观性，规范、工整的书写会给阅卷老师留下好印象，无意中老师会给出高出你文章实际水平的分数。即学即练：下面4幅图片描述的是星期天上午在中山公园里发生的一件事。请根据图片所提供的信息用英语为你校的“英语园地”写一篇短文。注意：短文须包括所有图片的主要内容。短文的内容要连贯、完整；参考词汇：货摊stand(n.);抢夺snatch(v.)；逮捕 arrest(v.)One Sunday morning，there were some people in ZhongshanPark.At a stand，a woman w
