说明：little表示“小”时的such.thatLittle表示“少”时的so.使用that
另外：
So many/few n that
So much/little不可数名词that
Such.that之间使用“不定式形容词单数名词”时的so.可以改成that结构，但这时so和形容词一起使用，其次是不定词和单数名词，然后是that结构：
that was such an important party that I had to take part in it。=
that was so important a party that I had to take part in it。
那是一个如此重要的会议，我不得不参加会议。
