来转换个间接引语

They said (that) what a lovely girl she was.
或者they said (that)how lovely the girl was.
因为that是引导宾语从句的，所以在句中可以省略。
上面四位的句子除了二楼都有毛病，一楼时态不对，三楼四楼的宾从里连主语都没有。二楼的对了，但是我觉得应该保持原句中感叹句的句式，就酱~~

They said that the girl is very lovely.

They said that girl was loverly

They said what a lovely girl was.

they said what a lovely girl was
