You can't expect your brain to do its best __you take care of it.A until B unless.
哪位牛人来拯救偶吧,这两个答案有什么区别么?
You can't expect your brain to do its best __you take care of it.A until B unless.哪位牛人来拯救偶吧,这两个答案有什么区别么?
首先说明一下,如果把这两个选项放在同一道题里进行选择,那肯定是一次不小的事故.
until在这里是时间状语的连接词,而unless是条件状语的连接词.
1 until 指的是:直到-- - - --,not -- -- until - -- - -直到-- - - 才- - - - -看例句:He didn't come home until he had done his work.(知道工作完成他才回家)
2 unless==if not :除非- - - - - She won't go with us tomorrow unless it is fine.(如果明天天气好,她就同我们一起去)===She won't go with us if it is not fine tomorrow
所以说这两个选项在语法上都是正确的 ,区别就是一个强调时间概念,一个强调条件概念.
not until 直到 才
unless 除非
选A
b,
a 这句话有语病。
选B,表示条件。
