Period 3　Grammar;一、品味语法 1．Had I not seen it with my own eyes，I would not have believed it. 要不是亲眼所见，我是不会相信的。 2．If you’d listened to me，you wouldn’t be in such trouble now. 如果你听了我的话，你现在就不会有这样的麻烦了。; 3．Without your help，we could not have succeeded.如果没有你们的帮助，我们就不会成功。 4．He felt very tired yesterday，or he would have attended the party. 他昨天感觉很累，要不然他就参加晚会了。; 二、讲解归纳 1．if的省略 如果条件从句中的谓语动词中含有were，had，should，可省略连词if，把were，had，should放在主语前构成倒装。如果条件从句是否定式，倒装时只能把not放在主语之后，不能用缩写式或把not放在主语之前。 ;Were I you(＝If I were you)，I would do more practice after class. 如果我是你的话，我会在课下多做练习。 Had you arrived(＝If you had arrived)at the station ten minutes earlier，you could have caught the train. 如果你早到车站十分钟的话，你就可以赶上火车了。 Should he come(＝If he should come)，tell him to ring me up.如果他来的话，告诉他给我打个电话。;2．含蓄条件句 有时句子表示的虚拟条件并不一定要用if从句来表示，而是通过连词or、otherwise、介词短语或通过上下文和句子的内在逻辑关系来暗示。 We took a taxi to the airport.Otherwise we would have been late. 我们打的去的机场，否则的话我们就可能晚了。 Without music，the world would be a dull place. 没有音乐的话，世界将会变得很无聊。 ; 3．if it be not for … 也是一种条件虚拟语气从句 If it had not been for the help of our teacher，we should not have made so much progress.要是没有老师的帮助，我们就不会取得那么多的进步。 If it had not been for me，you would not be free. 要不是我的话，你就得不到自由了。 ; 4．在有些复合句中，主句谓语动词和从句谓语动词表示的动作在时间上并不一致，这类句子称为错综时间条件句(混合式虚拟语气) If you had studied hard before，you would be a college student now. 如果你以前学习努力的话，你现在就是一名大学生了。 If I were you，I wouldn’t have missed the movie last night.如果我是你的话，我不会错过昨天晚上的电影。;Ⅰ.用所给词的适当形式填空 1．He hesitated for a moment before kicking the ball；otherwise，he ________________(score) a goal. 【答案】would have scored 2．But for the Party，he ________________(die) of hunger 15 years ago. 【答案】would have died; 3．I ________________(go) to visit him in the hospital，but I was fully occupied the whole of last week. 【答案】would have gone 4．If I knew her telephone number，I ________________ (give)her a ring now. 【答案】would give; Ⅱ.用虚拟语气改写下列句子 1．We want to buy a computer，but we don’t have enough money. 【答案】If we had enough money，we would buy a co
