（1）so＋形容词/副词＋that从句
The village is so small that it cannot be shown in the map.这村子太小，所以地图上没有。
unless的用法
unless意为＂除非，如果不＂，引导条件状语从句。unless引导的条件状语从句，若主句、从句的动作均未发生，则主句用一般将来时、祈使句或含有情态动词的句子，从句用一般现在时代替一般将来时。
I shall go unless it rains.如果不下雨我就去。
I won’t let you in unless you show me your pass.如果你不出示通行证，我就不让你进来。
