That he came back makes me happy.对主语That he came back 强调.

It is that he came back that makes me happy
强调句可以强调句子的That he came back makes me happy最前面的that呢？在句子里啊It is 【that】（原主语从句的that） he came back【that】（强调句的that） makes me happyAlthough the words are to say so.话虽如此，这句话对吗？语法没错，但我觉得怎么那么像中式英语呢比较好的一种翻译是That being the case你这种有点中式英语了结构和语法是正确的？也不对为什么要用be to do呢有be to do结构啊，表示什么？be to do 表示的是将来的时态，用在这里不合适so放在最后对吗？意思上是对的你就只要记住That being the case就可以了嘛，这个是比较标准的
