One Possible Version
As is known to all, with the improvement of people’s living standards, cars have become a popular means of transport, bringing great convenience to our life. However, they have also caused some problems such as air pollution and traffic jams.
How can we solve the problems then? As far as I’m concerned, riding bicycles is a good solution. For one thing, bicycles don’t need any petrol and they are energy-saving. For another, bicycles are environmentally friendly because they won’t give off waste gas. What’s more, riding bicycles is a good way for us to exercise and it is beneficial to our health.
题目分析：演讲稿主题部分应该阐述清楚事情的缘由、结果和要求。第一部分的内容应该以详细完整地介绍事情为主，具体地讲，包括事情的发生、发展及结局。第二部分的内容应该提出个人看法等。演讲稿以简单句为主要的表达形式。同时，演讲稿的语言必须有感染力，所以演讲稿可以使用祈使句、感叹句、强调句等句式来达到这种目的。写作时要注意适当地使用关联词承前启后，用词要得体，符合语言环境。
【亮点说明】文中使用了非常好的短语和句子为文章增色不少，比如As is known to all, with the improvement of people’s living standards, cars have become a popular means of transport,还运用了because引导的原因状语从句等等。并注意了句子的衔接如： As far as I’m concerned；For one thing…For another, What’s more等等。
