25、。 He _ _ after he waited for long.Unit 1 语法疑难解析WILL的四种用法详解助动词will+原形动词构成未来式，表示未来的动作。will用于第二人称的疑问句中,表示询问对方的意志或表示请求。Will you give me a cigarette? Or I will tell the boss.你给我一枝烟好吗?要不我就告诉老板。will+原形动词表示推测。This will be what you need.这大概就是你所需要的。 will+原形动词表示一种现在的习惯动作或倾向。She will stand there sleeping for ho

26、urs. 她常常站在那儿一连睡上几个小时。will+原形动词用于所有人称,表意愿。Ok, I will do it. 好，我愿意做这件事。 HAVE的用法详解1. 助动词have+过去分词构成完成时态。I have never seen such a strange man.我从未见过这么奇怪的人。Yes, he has been here twice but hasn't had his hair cut yet.是啊，他来了两次还没把头发理了。He's gone to your house. 他去你家了。2. HAVE+宾语+过去分词表示让某事由某人做。Can I have

27、 my hair cut now?你现在可以给我理发吗？Oh, you haven't had your hair cut yet. 噢，你还没理发呀。3. HAVE+宾语+原形不定词表示请或让某人做某事。Or I can have my assistant help me do it. 或者我可以让我的助手帮我来做。4. have作为本动词表示"有、拥有"的意思。No, I don't have much time. 不行，我没那么多时间。Oh, you still have many customers today.噢，你今天还有很多顾客呀【语法】动词篇

28、助动词have的用法1）have +过去分词，构成完成时态，例如：He has left for London.他已去了伦敦。By the end of last month, they had finished half of their work.上月未为止，他们已经完成工作的一半。2）have + been +现在分词，构成完成进行时，例如： I have been studying English for ten years. 我一直在学英语，已达十年之久。3）have+been +过去分词，构成完成式被动语态，例如： English has been taught in China

29、for many years. 中国教英语已经多年。动词篇助动词shall和will的用法 shall和will作为助动词可以与动词原形一起构成一般将来时，例如：I shall study harder at English. 我将更加努力地学习英语。He will go to Shanghai.他要去上海。说明：在过去的语法中，语法学家说shall用于第一人称，will 只用于第二、第三人称。现在，尤其是在口语中，will常用于第一人称，但shall只用于第一人称，如用于第二、第三人称，就失去助动词的意义，已变为情态动词，试比较:He shall come.他必须来。（shall有命令的意味

30、。）He will come.他要来。（will只与动词原形构成一般将来时。）有关have的短语惠特尼?休斯顿有一首歌，歌名是一无所有。Ill have nothing if I dont have you. 没有你，我将一无所有，多么深情的一句话。现在，我给大家介绍一些有关have这个词的短语。第一个词组是这样的：have ones eye on sb. 很自然地会想到是盯着某人看的意思，没错。In English, it means to be watching sb. carefully, especially to check that they do not do anything

31、wrong.中文就是密切注视，盯住，监视。那你能猜到第二个意思吗？Well, it also means that to be thinking about asking sb. out, offering sb. a job, etc, because you think they are attractive, good at their job, etc.中文很简单，就是看中，看上。Eg. Hes got his eye on the new girl in your class. 他看中了你们班新来的女孩。注意哦，是单数，eye 。我已经吃过饭了，Ive had meal. 这是一个完成时的句子，如果把meal 换成it , 虚指。Ive had it. 这句话的意思可就多了。听我慢慢说来。Ive had it. Im goanna to sleep. Here, it means that I feel sleepy. 我觉得很困，要睡觉了。Hes so overacted that Ive had it with him. 他太过分了，我受够他了。Have had it with sb. 受够某人。The car h
