高二有两大特征：1、教学进度快。一年要完成二年的课程。2、高中一年级的新鲜过了，距离高考考试尚远，容易玩的疯、走的远的时候。致使：心理上的迷茫期，学业上进的缓慢期，自我约束的松散期，易误入歧路，大浪淘沙的筛选期。因此，直面高中二年级的挑战，认清高中二年级，认清高中二年级的自己，认清高中二年级的任务，看上去意义十分重大而迫切。智学网高中二年级频道为你整理了《高中二年级英语必学五unit5要点总结》，期望对你的学习有所帮助！

除非你改变想法，不然我不可以帮你。
I want you to keep working unless I tell you to sTOP.
=I want you to keep working if I don’t tell you to sTOP.
假如我没说叫你停，你就得继续干。
注意：unless 不可用于假想的事情，因此当if...not引导非真实条件状语从句时，一般不可改用unless。

A. As B. if C. though D. unless
