五、名著精美语段选摘——在背诵中品悟如何写靓写美An excerpt frm Oliver TwistAnd s Oliver was left with nly the drunken nurse.Withut clthes, under his first blanket, he culd have been the child f a king r a beggar.But when the wman dressed him later in rugh cttn clthes, yellw with age, he lked exactly what he was — an rphan in a wrkhuse, ready fr a life f misery, hunger, and neglect.Oliver cried ludly.If he culd have knwn that he was a wrkhuse rphan, perhaps he wuld have cried even mre ludly.
奥利弗就这样被留下了，由那位醉醺醺的看护一个人看着。他光着身子，裹在毕生第一块毯子里，既可以是国王的儿子，也可以是乞丐的儿子。可后来老妇人给他穿上了由于年头太久而发了黄的粗棉布衣服，这时，他看上去和他的身份完全一致了—— 一个济贫院的孤儿，准备好了去过一种充满苦难、饥饿和不被关注的生活。奥利弗大声哭着。他要是知道他是济贫院的孤儿的话，或许他会哭得更起劲些。[点评]　本段话中运用虚拟句式“Withut clthes have been ...”，“If he culd have knwn have cried even mre ludly.”和渲染情感的词汇“drunken, rugh cttn clthes, yellw with age, misery, hunger, neglect”告诉读者Oliver 的出身也许高贵，但生来命运就主宰在别人手里，注定要经历坎坷与磨难。

信息安全包括的范围很广，其中包括防范青少年浏览不良信息、防范个人信息的泄露等。随着信息技术越来越广泛地应用于社会各个领域，社会发展对信息安全保障的要求不断增强，日益突出的信息安全问题也带来了新的挑战。以此主题来命题可以引导学生提高信息安全意识，特别是网络安全意识。如2020年北京高考书面表达记述居家学习期间，全班通过线上讨论以“自律”为主题的调研活动。
The Internet Harms Friendships(节选自北师大版教材必修第二册UNIT 4)While the Internet can bring peple clser tgether, it can als harm friendships.(开门见山，提出论点)Firstly, talking nline is n replacement fr face­t­face cntact — images really cannt replace a real­life smile r hug.❶Accrding t a parenting expert, Denise Daniels, cmmunicating thrugh a screen makes it mre difficult fr children t cncentrate r shw kindness t thers.As we knw, imprtant scial skills are develped thrugh direct cntact with ther peple.❷It is these skills that enable us t develp lifelng friendships.(分论点一：网上聊天不能代替面对面的交流。引用专家的说法，增强了说服力)
Secndly, the Internet can make peple self­centred — nt thinking f anyne r anything but themselves.Fr example, instead f having prper cnversatins with their friends, sme peple are nly cncerned with their nline ppularity — Hw many “likes” did I get? Hw many fllwers d I have？(两个设问，反映了人们的普遍做法) — thugh we knw that the number f “likes” r fllwers cannt cmpare t having lng­term and rewarding friendships.In additin, a lt f the cntent psted n scial media is shallw r trivial.Psts abut funny cat images d nt necessarily help frm meaningful relatinships.(分论点二：互联网使人们以自我为中心。例证法，有力支撑了文章的观点)
Thirdly, nline relatinships may nt be what they appear t be.❸Friendships are built n the basis f trust, and with nline cmmunicatin yu can never be 100 percent sure that the peple yu are chatting t are being hnest abut wh they are.Because f this, ging nline can be particularly dangerus fr peple wh are easily influenced r t trusting.(分论点三：网络关系可能并不是它们看起来的样子。讲道理，劝解警告)
In my pinin, friends shuld fcus mre n face­t­face cmmunicatin, and less n nline cmmunicatin.This is the best way t maintain healthy relatinships.(做出结论：朋友应该多关注面对面的交流，少进行线上交流)
由教材学写法1．学亮点词汇第一段中的 harm一词直截了当地指出了互联网对友谊有害。第二段第一句中同时运用了replacement 与其动词replace，既有力表达了面对面交流的不可替代，又体现了语言的韵律美。第三段中的shallw和 trivial准确描述了社交媒体上发布的内容的特点，且与本段中的rewarding，meaningful等描述友谊的词形成对比。
2．学高级句式句❶是一个简单句，句中运用了动名词短语作主语和“make＋ it＋adj.＋fr sb.＋t d ...”结构。句子结构紧凑，表意丰富。句❷运用了强调句型，强调了正是这些技能(通过直接与他人接触培养的社交技能)使我们建立了终生的友谊。句❸是一个多重复合句，句中and连接并列句。第二分句中，that引导名词性从句作形容词sure的宾语，省略了关系代词的定语从句 yu are chatting t修饰先行词peple，wh引导名词性从句作介词abut的宾语。各种不同的从句交替运用，层层展开，表达了丰富的句意。
3．学行文逻辑本文写作结构为“总—分—总”。文章在开头部分提出中心论点：互联网对友谊有害。在本论部分将中心论点分成几个横向展开的分论点，然后一一进行论证，最后在结论部分加以归纳、总结。整篇文章结构严谨，层次分明，有力地传达了作者的观点。

7．search engine 搜索引擎8．cntribute t 有助于，促成9．make full use f 充分利用10．n the Internet 在互联网上11．have an impact n 对……有影响12．make wnders 创造奇迹
Ⅱ.多积佳句——彰显表达功底1．Internet vting is quite ppular nwadays.Many peple are smewhat puzzled at the negative side f the vting, while sme are quite happy with it, and active in ding it.网络投票如今非常流行。很多人对投票的负面影响有些疑惑，然而一些人对它相当满意，并积极参与。
2．Peple spend s much time surfing the Internet at the cst f their health.人们以健康为代价，花大量的时间上网。3．With the rapid develpment f science and technlgy, a variety f high­tech prducts have spilled ver int each field in living.随着科学技术的迅速发展，各种各样的高科技产品渗透到生活中的各个领域。4．When a new prduct cmes int being, it must be tested ut befre it is put int use.当有新产品问世时，在投入使用之前，一定要进行检验。5．This makes it easy t make full use f the applicatin.这使得充分使用这款应用程序变得简单。
