应该是
She is quieter than he我觉得应该是She is quieter than him.和She is quieter than he is吧？两个都对丫，但是对于She is quieter than he貌似就不对了，没见过这种用法。你好。这样的句子叫“比较状语从句”，所以than的後面是主语he,具体的就是：She is quieter than he is-------只不过省略了is.或许，你学英语的时间不长吧？难以理解的还在後面。嗯，我学英语的时间是不长。才初中英语老师而已，只不过觉得than后面如果只给一个空的话，就只能填him，而不能填he。him一般用於口语，he用於大多数场合，更常见。又如：She is taller than I/She is taller than me两句都对，但这句你必须选择 I ：She is taller than Iam.
