If + 一般现在时 情态动词 (can/may) If you finish, you can leave. If + 一般现在时 祈使句 If you see him, tell me. 2. 非真实条件句（虚拟语气，较难实现的条件） 结构：If + 一般过去时，主句 + would/should/could + 动词原形 条件从句 主句 例句 If + 一般过去时 would + 动词原形 If I were you, I would study harder. 四、unless 的用法 unless = if not（除非，如果不） 例句 同义转换 You will fail unless you study. You will fail if you don't study. Unless it rains, we will play. If it doesn't rain, we will play. 五、易错点分析 1、时态错误（"主将从现"原则） If it will rain, I will stay home. If it rains, I will stay home. 2、if 与 unless 混淆 You will fail if you study.（逻辑错误） You will fail unless you study. 3、条件句中的 will 使用错误 If you will come, I will be happy. If you come, I will be happy. 六、记忆口诀 “条件从句if引导，unless表示除非了。 主句将来从句现，'主将从现'要记牢。 时态一致很重要，will不在条件跑。 真实条件可能现，虚拟语气愿望表。” 1． _____you don't give up(放弃)，your dreams will come true.
