　　阅读写作(二十)　议论文写作之陈述观点型、正反观点型、说明利弊型

　　阅读写作(二十)[议论文写作之陈述观点型、正反观点型、说明利弊型 ]

　　阅读写作(二十) │ 写作点拨 写作点拨 议论文是一种剖析事物、论述事理、发表意见、提出主张的文体。论点、论据和论证是不可缺少的三要素。近年来，高考英语书面表达中对开放性议论文文体的考查有递增趋势。传统的书面表达是一种控制性写作，即通过表格、图画及文字等进行要点提示，并规定作文的人称、时态、文体等；而开放性议论文则给出一定的素材或话题，让考生在此基础上自由发挥，对所给材料进行判断、论述和发表个人观点。这种试题有利于体现学生个性发展和思维的灵活性，符合新课程的理念。 对于绝大部分开放性议论文，基本上适宜用“三段式”的写法，具体来讲就是： 第一段：开头——引论。用以引出一个令人关注的问题(topic)，阐明观点或看法。 第二段：主体——本论。全文的主要部分，对提出的问题进行分析、推论(supporting sentences)，运用材料对观点进行论述，使论点得到足够的支持。 第三段：结尾——结论。对主体部分内容作出概括，明确论点所要解决、论证的问题。有时则是提出建议或给出解决问题的方法或策略。 阅读写作(二十) │ 写作点拨 议论文的写作较之于其他题材的文章相对有规律可循。而且文章的开头具有一定的共性，行文中段落的过渡和观点之间的转化也极具相似之处。因此使用规律性的语句不但可以显得条理清楚，而且可以提高文章档次。

　　阅读写作(二十) │ 写作点拨 阅读写作(二十) │ 词句模板 词句模板 1．议论文常用逻辑联系词语包括：in my opinion, personally, for the sake of, clearly, obviously, surely, undoubtedly, hence, moreover, besides, in addition, what's more, additionally, furthermore, generally speaking, last but not least(最后的但同样重要的), in short, all in all, in conclusion, in brief 等。 2．段首常用语：

　　Recently, we had a discussion on how to make English learning relaxing and fun. Most students believe that there are many ways to do so. First of all, we can have more interactive activities in class, such as discussions, interviews, story－telling and role－play. In this way, we can have more fun learning English. Secondly, we can take part in more out－of－class activities like English speech contests and English evenings. Through these activities we can improve our English skills in an easy and relaxing way.

　　阅读写作(二十) │ 词句模板 Thirdly, we need to find more opportunities to communicate in English with people, whether they are English teachers or classmates, foreigners or Chinese, because using English is the best way to learn.

We can also watch English programs on TV or join English clubs or make English pen－friends on the Internet. All in all, what we need is more free time and more space.
