比如“该不该鼓励公共交通”这个话题,可以衍生出公共交通可以帮助居民降低生活开支。那么这一个点的论证就可以这么写:
Topic sentence:To begin with,this practice can reduce citizen‘s living costs,thereby enhancing their quality of life.
原因:Once public transport is free to public,people who ride them to work can save a significant proportion of weekly expense.
结果:As a consequence of that,the saved money can be used for other purposes,such as food and leisure activities,to promote the quality of life.
