这句话的英语语法问题
To change the situation ,some effective measures should be taken before things get worse .为了改变这种情况,在事态进一步恶化之前必须采取有效措施.
句子的主语和逻辑主语是否必须一致?
请具体分析.
请看清，我的问题是：change the situation 的逻辑主语是什么？（也就是动作执行者是谁）我知道是“某人”
按照英语语法，逻辑主语是不是必须与句子主语一致？我写的句子，逻辑主语是“某人”，而句子主语是“some effective measures 是不是我写的句子存在语法错误？

此句可改写为some effective measures should be taken to change the situation before things get worse,句子的主语是measures.measures的逻辑主语是采取有效措施的人.someone take some effective measures to change the situation.to change the situation 是目的状语.

To tell you the truth, this sentence might be correct.
句子的主语不是不定式的逻辑主语，但是，和上面这句话类似，在口语中谁都知道这不定式的逻辑主语是“人们”，“我们”，和to tell you the truth一样，看成是独立成分（不是独立主格结构）单独作状语，类似的还有Generally speaking, Judging fro...

这句话用了被动语态（should be taken），句子的主语和逻辑主语都是同一个（some effective measures）
前面的to change the situation是状语，表目的，修饰整个句子

这句话没错！

people

change the situation 的逻辑主语是人

这句话非常正确！
