你好，作文类型较多，就简单议论文而言，先记着两点：1、务必写清楚自己的观点。2、务必表明每段写了什么。就此，一些表首段观点的亮点句型比如：currently, whether to do sth has provoked a heated discussion in the public. as far as i am concerned, I am in favor of ...;表示每段写了什么的过渡句如：basically, my reasons/suggestions are listed as follows. 表示结尾强调观点的句型为：To sum up, there is no doubt that ... is my best choice and therefore it is supposed to be further encouraged. Only in this way can we ...。对于比较好的关联词如首先（to begin with,/first and foremost, ）其次 （what‘s more/furthermore）最后（in addition, /last but not least）字数有限，希望有所帮助，谢谢~
