这句话怎么写成定语从句,

你搞错了.that may be...education 本身就是定语从句,修饰现行词 political changes.
你还想怎么改?
你分不清名词性从句和定语从句?你是吃饱了撑着？这么改有什么意义？ 根据上下文，给定语从句加入合适的主语，变成：使……可能的/使…发生，不就行了？意思一样。....without political changes (that/which) they may make possible/ take place only with broader formal education.在线吗？明白了，给个回答。谢谢方月灌木的共鸣。不论是原来的that还是我改写后的that/which都是指代 (political) changes.原来的可拆开，这么理解比较直观：....without political changes. The political changes may be possible only with....如果你不想把这两个简单句合并成关系更加密切的复合句，这样的表达也不好，没有必要重复the political changes, 至少你也该用一个“人称代词, they = the political changes.e.g. ...without political changes. They = The political changes may be possible only with....但如合并成复合句，就不能再用they，因为在性质上人称代词不可以引导定语从句的，所以就必须用”关系代词“之一来引导了。我改写后的从句中的 they =poor countries.e.g. Thus poor countries...without political changes (that/which) poor countries may make () possible or take place only with....( Poor countries may make (the political changes) possible or take place only with....因为是复合句，( the political changes= that/ which... ) 被替换成关系代词后，再提到先行词后，就 （）了。希望你能明白。最好自己要拿书法书学习。
