How Will AI Affect Our Life_ 31
How Will AI Affect Our Life?
姓名：黄同学 学校：广州市第二十一中学 分数：97
In recent years, with the development of modern technology, Artificial Intelligence has become a hot topic among people, especially among the young, and the heated debates are right on their ways. People's opinions on AI vary from person to person. Some welcome the AI and consider that it will be beneficial for them, but I regard it will affect our life to some degree. It is universally acknowledged that AI will assist us to do what we can do by hand instead. It would change some people's positions. For instance, the application of AI in technology and engineering, because of losing the opportunities to deal with the information, will prompt many employers to change the ways they work before. Subsequently, the drawback is that we are becoming more dependent on this technology in our interactions with one another. There is a growing trend for people to keep in contact by texting or social software like Wechat instead of having face-to-face interactions, which leads to a sense of alienation among individuals. Meanwhile, with the popularization of AI, the influence of AI is in mankind's mode of thinking and iconoclastic conceptions, and it will be changed at any time. For example, once some professors choose to trust the judgement and decision from AI, it will make them become lazier and thus they tend to neglect the responsibility to solve the task. Hence, in my view, on condition that humanity keeps relying on AI excessively, the competence of thinking will considerably decline. In conclusion, I hold the view that despite AI can improve the efficiency of labor, there are some harmful effects for individuals. That's why I argue that AI will affect our life from time to time.

should和would用法
Should & Would 用法 should的用法： 1、（用于间接引语，表示）将 We said we shouldn't arrive till 6. 我们说过我们六点才能到。 "If it should rain tomorrow, the sports meeting would be postponed." "要是明天下雨,比赛就延期举行。" 2、（和that一起用于表示意愿的动词和形容词之后） He was keen that she should go to college. 他渴望她能上大学。 3、（在条件句中与第一人称连用）可能；会 I should have bought it if I had enough money. 如果当时我有足够的钱，我会把它买下来的。 4、（表示责任或义务）必须，应该 Children should obey their parents. 儿童应该服从他们的父母。 5、（表示可能之事）可能 It should be fine tomorrow. 明天可能天晴。 6、（表示不确定）万一 If I should see him, I'll tell him. 万一我见到他，我就告诉他。 would的用法： 1、[表示过去将来时, 用于第二、三人称](第一人称英国用 should, 美国用 would) 将, 会 He said he would come.他说他要来。 2、[表示意愿]愿; 偏要, 肯 He would eat nothing.他不肯吃东西; 他什么也不愿吃。 I told him not to go, but he would not listen.我叫他别去, 可他偏不听。 3、[表示过去的习惯动作]常常, 总是 He would sit for hours doing nothing.过去他常常坐几个钟头什么事也不做。 He would come to see us on Sundays.过去星期天他经常来看望我们。 4、[表示推测]大概, 该是 I would be about ten when my brother left home.我哥哥离开家时, 我大概十岁左右。 5、[表示某种假设的意志]想要, 愿意 I could do so if I would.要是我愿意, 我能够这样做(但我不愿意)。 If you would do this for me, I should be grateful indeed.若是你愿意为我做这件事, 我将万分感激。 6、[表示虚拟, 假设, 虚构, 用于虚拟条件句的主句第二、第三人称, 美国也用于第一人称]要, 会, 就会, 将要They would be killed if the car went over the cliff.如果汽车翻在悬崖下, 他们就会丧命。 They would have been killed if the car had gone over the cliff.如果汽车当时翻到悬崖下, 他们早就丧命了。 7、[表示请求或个人想法、看法, 使语气更婉转]请 Would you kindly show me the way to the station? 劳驾, 请问到车站的路怎么走?

Would that I were young again. 我若能再年青些该多好啊! 1
would的用法
will, be going to 和would的用法区别 will, be going to 和would都有将要或将会干什么的意思，但是在用法上有很大的区别。 will 通常表示确定或计划好了的将来会/要发生的事，一般不以个人的主观意志为转移，或者主观上决定了不再改变的事。比如：I will be 30 next month（不是我啊）. It will rain tomorrow (根据气象台的报道). I will donate $1000 to my alma mater（也不是我啊）。 be going to通常表示即将要做或发生的事，主观愿望或判断很强烈，中文里相当于“打算”。美语口语常说成gonna. I am going to play soccer this afternoon. It's gonna be raining (我的判断). I am not gonna buy that car right now, but I'll do it after I get a job. （感受一下going to 和 will的差别) 两者的区别还在于，will 较 be going to 更书面化一些，be going to更口语化，通常说成gonna, 但说be going to也很正常，不过，如果你说英语不是那么地道就不要说gonna，否则人家反而觉得别扭。好比一个普通话都说不清楚的南方人，到了北京，本来人家也不会笑话你什么，不过你什么都没学会就，“边儿去”倒说得挺标准，还老用个没完，那听了可就有点儿别扭了。另外，有时候will 和be going to 的区别 也不明显，两者常可以互换使用，初学者不用太为计较。 至于 would，很有讲头啊。它原来是will的过去式。所以它的第一功能是表示过去将会发生的事。 比如： He told me he would not eat my mom's pancake. The baby was born to a poor farmer's family. Nobody knew he would become the 21th president o f United States of America 40 years later. （这是我随口瞎编的啊） The driver would have been in trouble if he'd drunk that night. would的第二层用法是最常见的和like或love联用，表示很想或很愿意做一件事，love则比like更为强烈。有些朋友想学一些最基本实用有趣的东西，这里我就引用一个美国朋友给我发的email中的一段，他恰好like和love都用了。We would like you to join our family for a traditional Christmas dinner on 25 December. We woul d love to have you come to Estes Park and enjoy a meal at our table and see some of our winter beauty. would的第三层用法在于，表示客气，猜测或不确定等软化的语气。我们知道，英文里很多情愿动词 都有这个用法，比如may-might, can-could (将另文介绍)。 客气：Your assistance would be highly appreciated. Would you give me a hand? Would you shut up? 猜测或不确定：Jim would not stay there for a long time. 如果这里用will或is going to 来取代，则表示说话的人有足够的理由或证据做这个判断，Jim计划中不会呆太久，或他这次没打算呆太久。用would只表示一种猜测，基于对Jim这个人一贯做法的了解，而不是瞎猜的。言下之意就是说，（以Jim这个人 的一贯做法），他是不会在那儿呆太长时间的。 由此引出would的第四种用法，表示一种倾向和一贯做法。比如：I would say I don't like Bush's administration. 这里省略的潜台词是，（如果你一定要我下一个
will的用法

will的用法
一、will的基本用法是： 1)will(would)表意愿，主要用于第一人称；will指将来，would通常用于间接引语，指过去的将来。如： I won't argue with you. 我不愿意跟你争辩。 I said I would do anything for him. 我说过我愿意为他做任何事。 2)will(would)表拒绝，用于否定句。如： The doctor knows I won't be operated on. 大夫知道我不想做手术。 He was wet through, but he wouldn't change. 他全身湿透了，但不想换衣服。 如主语为物，则意为“不起作用”。如： The drawer won't shut. 抽屉关不上了。 My fountain pen wouldn't write. 我的自来水笔不能写字了。 3)will(would)表习惯或反复发生的动作。如： John will fall asleep in church. 约翰做礼拜时老睡觉。 Most often we would find him lying on a couch, reading. 我们经常看到他躺在一张长沙发上看书。 有时重读will就有批评的含义。如： You will keep forgetting things. 你总是不断地忘事儿。 will可表客观事实。如： Gold won't dissolve in hydrochloric acid. 金在盐酸中不溶解。 4)will(would)表请求，指将来，用于疑问句。如： Will you dine with me tomorrow, Lewis? 刘易斯，明天你同我一道吃饭好吗? 如用would，则语气更客气。如： Would you mind closing the door? 请关上门好吗? 5)will(would)用于if引导的条件从句，亦表意愿。如： No, we are not going to quarrel at all if you'll only let me talk. 不，我们根本不会吵架，只要你让我说话。 6)will表料想，指现在或将来；用于进行式时指现在；用于完成式时则指过去。皆用于第二、第三人称。如： This will be the school, I believe. 我想这大概是那所学校。 Hurry up.
