英语语法问题

I promised that I would change the situation
这句话可省略that吗？如不行，请说明为什么，从句里为什么要加连词？它的作用是什么？如果不加连词会有什么结果？谢谢！

Answer 1

这是一个宾语从句，宾语从句中that一般情况可省 ,但that在引导宾语从句时也并不是任何情况下都可以省略。在以下情况下，that不能省略。
1． Everybody could see what happened and that Tom was frightened.(and连接两个宾语从句，that宾语从句放在and的后面时，that不能省略。)
大家都会看出所发生的事情并知道Tom非常害怕。
2．I know nothing about him except that he is from the south.(that引导的宾语从句作介词宾语时，that不能省略。)
对他我一无所知，只知道他是南方人。
3．That he ever said such a thing I simply don’t believe. (that从句位于句首时，that不可省略。)
4.We decided, in view of his special circumstances, that we would admit him for a probationary period. (主句谓语动词与that从句之间有插入语，that不可省略。)
所以that可以省略

Answer 2

不可以省略，这是宾语从句，这是固定句型的，像I believe/promise/suggest/think that...不能省略，如果你省略了，这个句子中就有2个谓语动词，promise和would这是语法错误，所以不可以省略。

Answer 3

解释如下 The land over which a government has control is its territory. 这里control是名词，指控制权。故看起来和动词原形一样。 control over是有控制权。由于定语从句，over提到which前面了。这种句子把主干提出来就容易看懂了。
