2．(演讲注意事项)要面带微笑；要讲慢些，讲清楚。

　　Be sure to wear a smile on your face.Besides, remember to speak slowly and clearly.

　　→Be sure to wear a smile on your face when you speak, which will make you relaxed.Besides, remember to speak slowly and clearly so that you can leave a good impression on the audience and judges.

　　[分析]　加蓝部分是根据语境所追加的成分，如"which will make you relaxed"指出"演讲时微笑"的好处；"so that you can ..."为"讲慢些，讲清楚"的目的，留下好印象是"演讲"效果之一，也是能否获得评委青睐的因素之一。适当增加与所给信息相关的时间、原因、结果、条件、目的等成分来表达细节内容，能够使习作流畅、丰满，达到应有的表达效果。
