i seen so good an adventure film as crouching tiger,hidden dragon为什么是have seldom 不是had seldom,seldom have
问题描述：
i seen so good an adventure film as crouching tiger,hidden dragon
为什么是have seldom 不是had seldom,seldom have
答
现对现在来说很少看到这类片子,当然用have seldom seen
had seldom seen 是过去完成时,如果句子中找不到一个特定的过去时点,是不可能用的.因为过去完成时指的是过去的过去
seldom have 这个不对,seldom 频率副词得放在助动词之后
