so作程度副词用..I like her but not all that much .解释说这里that是程度副词,相

I like her but not all that much .
这里so much 表示“非常”的意思
Sometimes it was a bit boring to work there because there wasn’t always ______ much to do .
这个句子翻译过来是“在那里工作有时候会觉得有点烦,因为经常没有事做.”句子里面有个there be结构,后面缺少一个名词,四个选项里面只有that可以用作名词,这里that不是当做程度副词使用的.
