外研版英语九（上）Module 5模块语法详解与训练模块语法详解状语从句（4）以及表示“禁止做某事”的结构一、if引导的条件1. if从句的定义：if意为“如果；假如”，它引导的句子表示某事发生所需的条件，即“在……条件下，某事才能发生”，在句子中充当状语，因此称之为条件状语从句。if引导的条件状语从句表示假如有从句的动作发生，就会有主句动作的发生。if引导的状语从句不是指已经发生的事件，而是指能够发生或可能发生的事件。If it rains tomorrow, we won’t go for a picnic. 如果明天下雨，我们将不去野餐If you do not feel well, please go to see the doctor. 你如果感觉不舒服，就去看医生吧。2. if从句的位置：if引导的从句可以放在主句之前（必须用逗号隔开），也可以放在主句之后。如：If I have enough money, I will travel around the world. 如果我有足够的钱，我就去环游世界。=I will travel around the world if I have enough money. 如果我有足够的钱，我就去环游世界。3. if从句的时态：①如果主句是一般将来时，从句则用一般现在时（主将从现）。如：If you join the party ,you will have a great time. 如果你参加聚会，你将会过得很开心。If you often listen to English songs, you will like English. 如果你经常听英文歌，你将会喜欢英语②如果主句含有must, may, can 等情态动词，从句也要用一般现在时（主情从现）。如：If you finish the homework, you can go home. 如果你作业做完了就可以回家了。 If you want to lose weight, you must/should eat less bread. 如果你想减肥，你必须少吃面包。③“if从句+祈使句”，如果主句是祈使句，从句用一般现在时（主祈从现）。相当于汉语的“如果……，就……”，常用来表达建议。如：If you want to go, please tell me. 如果你想去的话，请告诉我一声。If you want to know more about it, call now. 如果你想了解更多内容，现在就打电话吧。4.“if 引导的条件状语从句”与“if引导的宾语从句”的区别：①if引导条件状语从句时，意为“如果，假如”，当主句时态是一般将来时时，从句时态用一般现在时。如：Don’t go and play football if you don’t finish your homework. 如果你没有完成作业，不要去踢足球。If she gets up a little earlier, she’ll have time to eat breakfast at home. 如果她早点儿起床，就有时间在家里吃早餐。②if充当宾语从句的连接词时，相当于whether，意为“是否”，遵循宾语从句的时态规则。如：  I don’t know if the train has arrived. 我不知道火车是否到了。---- I don’t know if he will come. 我不知道他是否会来。 ---- He will come if it doesn’t rain. 如果不下雨，他会来的。二、“禁止做某事”的结构①No+动名词（最常用）。如：No joking! 不要开玩笑！// No parking! 禁止停车！// No smoking. 禁止吸烟。// No shouting.  请勿喧哗。No shouting! The students are doing their homework quietly. 禁止喧哗！同学们正在安静地做作业。②No+名词。如：No photos. 请勿拍照。//  No food and drinks. 请勿饮食。③(肯定或否定)祈使句。如：Keep off the grass. 请勿践踏草坪。// Don’t make any noise. 不要吵闹。// Don’t touch. 请勿触摸。④主语+mustn’t/ shouldn’t/ can’t+动词原形。如：In most museums you can’t make any noise. 在大多数博物馆里禁止喧哗。You mustn’t take photographs of the exhibits in museums. 在博物馆里不得给展品拍照。⑤You aren’t allowed to+动词原形。你不允许做某事。如：You are not allowed to touch the exhibits. 不要触摸展品。You aren’t allowed to play football on th road. 你不准在马路上踢足球的。▲“禁止触摸。”的多种表达：①No touching.③Don’t touch.④You mustn’t/can’t/shouldn’t touch.⑤You aren’t allowed to touch.模块语法即学即练一、单项选择。(    ) 1.
