到底什么是thesis statement?英文写作中的thesis statement该如何过渡?请举例说明

thesis statement“主体论述,论证过程”,常常处于论文的中间.
Thesis statement is a statement or illustration of the thesis,that is the author's view,by means of some examples and expatiation and conclusion(阐述和推断),normally the statement of thesis is arranged in the intermediate paragraphes(中间的段落）.
Thesis statement 在整个文章中有着重要的作用,它是整个文章的灵魂,所以写好它,就等于文章写了一半出来,在写thesis statement 必须要做到以下几点：
1.一个好的论文必须有一个Point 和 purpose
2.考虑一下你为什么要写这篇论文
3.你的文章为什么值得读者去读,他们能从中得到什么
4.你要说服读者去做什么,给他们带来什么启示
5.thesis statement 必须是一个完整的句子,去陈述这篇论文的结论和为什么会有这个conclusion.
下面是一些thesis statement 的例子,可以慢慢体会,从中学习.
Thesis Statement Examples:
· America is experiencing a health care crisis because of an aging population and rising health care costs.
· Health is achieved through a combination of exercise,proper diet,relaxation,and strong social relationships.
· The North won the American Civil War because of its larger population and stronger industrial base,which allowed it to make more weapons and supplies than the South.
