It is still a good idea to read the first sentence or last sentence in each paragraph a little more carefully. (第一次阅读是skimming，这里学生只要看文章标题，再快速看段落主旨句尤其是最后一段验证即可，用时大概1分钟；讲解时得到答案的方法更重要；核对答案时可以叫2-3名同学分享他们的答案和依据。)教学设计说明：第一遍阅读是略读，快速阅读来获取文章主旨，这是理解文章的第一步。3. ScanningMoving your eyes quickly down the page to find the specific information.教学设计说明：通过阅读获取信息回答问题后，理解文章要点，进一步理解文章。在原文做标记找答案的阅读习惯养成。通过超链接的方式展示问题答案在原文中的位置，给中下层次的学生便利，提高课堂效率。4.intensive readingT: OK, now lets move to some details of the passage.
