According to the Guangzhou government Office, the bus rapid transit (BRT) system will be piloted on Zhongshan Road (from Tianhe intersection to Xiayuan Section) this year. The BRT system will be adopted throughout the city before the 2010 Asian Games, said Mayor Zhang Guangning.

What’s more, the performance of BRT system will surely speed up the ride and save much time. Last but not least, it will definitely bring about a great advance of public buses and also reduces air pollution. However, some people hold the opposite opinion that BRT system may give rise to a lot of problems, such as

此题为议论文,从文中提示来看,我们必须从利弊两方面论述,符合对立观点的题型。所以文章条理一定要清晰,论点简明扼要的提出,论据要表达完整。可以选择一些表示对比,转折的连词及句型。时态很明显要用现在时。

   议论文是以议论为主要表达方式的一种体裁,它主要用于剖析事物,论述事理,发表意见,提出主张,作者可以通过摆事实,讲道理,直接表达作者的观点。笔者认为话题作文和议论文有重复之处,但还有一些是关于学校或社会存在的某些现象及焦点问题,要求学生表明见解,进行论述。在此期中笔者将二者不予以划分,只侧重于议论文在技术形式及内容上的点拨,“以篇盖全”,从中掌握二者的共性。我认为在写议论文时,应注意以下几点:

1. 条理要清晰,观点明确。

刚开始工作时,我是顾及不上备学情的,但有了一些教学经验,特别是比赛经验后,我发现,没有对学生的清醒认识和准确分析,就无法上好一节课。

注意学情就是根据学生的具体水平,设计教学内容,设计教学步骤,设计问题,这些工作都要有的放矢地去准备。

备课不是一个单纯的知识收集过程,教师必须动脑筋,抓住文本的特点,结合学生的情况,不可追求面面俱到,又必须尽量做到能兵来将挡。这个过程是为我们上课做准备的,更是我们自身积累和提高的最好途径。

2.、注意资料的真实程度

   现在的网络是个万花筒,有很多可靠、可信的的信息来源,但也有人为了迎合某受众的口味,会传播很多查无实据的信息。我们教师在搜集备课资料时,如果不经过甄别、遴选,难免会选中一些不合适的资料。所以,我们不能只顾迎合学生的猎奇心理,不能只想求新而道听途说。做学问要严谨,特别是做教师,要传递信息给学生,就必须注意资料的真实性。
