Hello, both and girls, welcome to my class. today. We are going to learn how to use now finite book doing morning. I won a composition about the spring festival this year yesterday. Could you please give me . some suggestions? An excEllent passage, but the sentence patterns are relatively simple. Actually, in addition to using end, you can try the long final books to make IT more vivid and attractive. What is non finite . verb in linguistics? On finite verb is a verbal phone that is not limited. The bio subject is not fooling, inflected by categories that are marked inflationary in language such as tense t mood, number, gender and person. There are four kinds of non finite box giant present participle, fast participle and to infinity, which can function as subject, object, predictive attribute, adverbial and compliant. So why do people use non find verb? Now let's . talk about IT. The british wants a made rule. A simple sentence has only one. For example, I admired the moon on the new autumn festival. The predict book. Admired is the key of the sentence IT terminals. What the whole sentence is talking about, what if I want to see? I ate moon cakes while admiring the moon, so they introduced constructions and sentence can be writing into, I admire the room and eight moon cakes on the new autumn festival. If I admire the moon, ate moon cakes, try to with my parents, but I don't want to use any construction. How to solve the problem? We need to change other works into non final votes. How to use non finite verb in writing? Good question. Now that we have known why people use non final book today, let's focus on the frequently used form doing, which functions as adverbial in a sentence to make your conversation impressive. In fact, doing as avia can be classified according to different functions in the context. Now let's watch the video to spend out some examples. The fifty day of the eighth lunar on is a medaled, mn festival. According to the legend in asian times, there were ten sounds in this guy semur anew, sly, and to the strong exposure and extremely hot temperature made people's lives a misery, a hero and whole e came along, shut down dicon ons and saved to the world to reward his bravery between mother. Give him an election as a reward. 嫦娥，后羿，why track the lexus a accident and became in model 3。Models cannot remain in a model. Will SHE had to leave the ascended to the moon and could only watch the human world from a far. Doing can be used to describe actions, and how to use IT depends on when the action of the verb happens. Usually there are two different situations. First, when the action of doing takes place, at the same time as the action of the predict book, we can use the following sentence pattern. For example, just as the video shows in the sentence, SHE left the earth and ascended to the moon. The action of left and ascended occurs almost at the same time, so we can also write like this, he left the earth assending to the moon. Second, when we want to to emphasize that one action was done after another action, we can use heaven done born like this. In the video, we can easily find that after后裔saved the world，the queen mother gave him an elexa as a reward. So if we want to use a long, finite verB2Combine these two sentences, we can say, haven't saved the world. The queen mother gave him an elected as a reward is the sentence right now? Please be a drug to think about IT. Here, you should pay careful attention in the examples above, now find that works, and predit folks in each sentence share the same subject. And in this sentence it's apparent that the action of saved the world and give an elexa are done by two different subject, so we can say IT like that. Instead, the sentence should be changed into heaven saved the world后羿was giving an elected as a reward is IT clear。Now let's go on to find other functions of doing form. As adverbial doing form can also be used to present results in the sentence. 后裔shut down nine songs and safe world the action saved the world is the result of the action shut down nine sons so the sentence can be changed into后裔shot down nine songs，seven the world here shoes another function of doing form, explaining the reasons they focus on distances. 嫦娥drank the alexa by accident and became immortal，obviously drunk. The elected by accident is used to express the reason why嫦娥became in water，so IT can be changed into drinking. The election by accident, 嫦娥became in water。In addition to the examples above, here I show you a table of doing from according to different functions in context. After learning so much, can you use non finite works in these four sentences to polish your writing? Have a try. I think the four sentences can be written into one. First of all, having clean the room and done the spring festival shopping, we cut and put up paper cut outs. Two after that, we put up spring festival couplets and new year pictures, making the house three. After the sun went down, we gather together to have a reunion dinner with our families and watching C, C, T, V new year gal for being very happy in the spring festival and looking forward to wait next year. And the non finite verbs in the first and third sentences are used to describe behaviors, while the second for presenting the result and the forth for . explaining the reason we are done. IT seems that you have mastered IT quite wear AI. 评估，第一篇得分81分，第二篇得分96分。第一篇作文是一篇合格的、内容完整的作文，但它更像是一份活动清单，语言较为平淡且有一些语法错误。第二篇作文则是在第一篇的基础上进行了成功的润色和升级，通过运用分词结构这一高级语法技巧，极大地提升了句子的复杂度和高级感，使文章更符合英语的表达习惯。第二篇句式结构丰富多变，巧妙地运用了分词短语，将多个动作有机结合，使文章读起来更流畅、更紧凑，这是两篇作文最核心的差异。比如第二篇使用了having cleaned and done这个现在分词的完成式，清晰地表达了打扫卫生和购物这两个动作在贴窗花之前已经完成，时间的层次感立刻显现出来。Now, do you know how to use no find verbs to punish your writing?
