雅思写作语法备考写作中的主题句如何写好呢

雅思托福考试是一个非常有难度的考试，相信很多在备考阶段的小伙伴们，每天都在关注一些雅思相关的消息。有同学问：雅思写作语法备考：写作中的主题句如何写好呢？？今天，一起来看看吧。

例1　Whats more, the outer space research should be maintained for its adventures, By adventures I mean that the astronauts are risking their lives. lt is true that some astronauts like those in challenger are devoted to the space programme. So, whether space research is valuable for welfare of human beings isalso a controversial problem.

【解析】：

第一句是主题句，表明观点：太空研究应当继续下去。

而这里的 for its adventures就只能理解为：为了探险(这里用词不当)。接下来支持句说:宇航员在冒生命的危脸，进而提到挑战者号的宇航员们为大空事业献出生命。最后，得出结论太空研究对于人类的幸福是否具有价值这一问题仍然具有争议性。

从逻辑上说:主题句是正面观点，即支持太空研究。而接下来的两个支持句是反面观点，其一，危险;其二，更危险，有牺牲。最后的总结不正不反观点，说太空探索具有争议性。

那么，短短一个段落里，支持句不但没有支持主题句，反而反对主题句这不是策反吗?和主题句反看来，对看干，最后得出一个不正不反的结论，那就等于是走了一大圈最后又回到原来的出发点何!

①首先改掉语法错误:标点符号和大小写

②其次改逻辑问题，下面修改了主题句，当然也可以修改支持句;

③最后的结论也要出水芙蓉，浑然天成，反正就是要符合逻辑!

改正后的段落：

Whats more, the outor space research should be restricted to a certain extent，for we have paid too heavy costs in the past 40 years. Astronauts are risking life and limb in probing into the unknown frontier. On January 28, 1986, with an unquenchable desire to explore the mysterious and beautiful universe, seven star voyagers of the space shuttle Challenger embarked onto the miraculous universe yet lost their lives in the ensuing explosion only 70 seconds after the launching.

Those unparalleled scientists devoted themselves to the space shuttle program,which is an all-time loss to our universe program.Hence, in order to prevent such atragedy from recurring, more scientific work on space programme should be done before we finger the infinite universe again.
