【英语】2019届二轮复习阅读理解解解题指导教案(13页word版)
2019届二轮复习阅读理解解解题指导 第一、二、三课时 一、学情分析 阅读理解在考试当中那个占了很大的分值,是学生参加各类英语考试必做的题型之一,然而也是考生们失分最多的板块之一。尤其对于基础较差的学生,阅读理解上想要得到理想的分数非常困难,大部分英语老师都会说“得阅读理解者,得英语考试天下”,虽然夸张,但不无道理。 二、课标&考纲分析 从历年的高考阅读理解命题原则来看,命题思路及命题的特点基本一致,即“注重语境,突出语篇,强调检测考生综合应用的能力”,既有利于高校的选拔,也有利于在中学英语教学中推进素质教育。从试题内容方面看,所选的材料贴近生活,具有时代感,知识覆盖面广,生活气息浓郁,集基础性、交际性、文化性和能力性于一体,不但强调语言基础知识的运用,而且也检测了考生的语言运用技能,体现了《考试大纲》的要求。《普通高中英语课程标准>>对阅读理解的目标要求:《普通高中英语课程标准》在语言技能部分中对“读”的目标是这样要求的: (1)能识别不同文体特征; (2)能通过分析句子结构理解难句和长句; (3)能理解阅读材料中不同的观点和态度; (4)能根据学习任务的需要从多种媒体中获取信息并进行加工处理; (5)能在老师的帮助下欣赏浅显的英语文学作品; (6)除教材外,课外阅读量应累计达到30万词汇以上。 《考试大纲》对阅读理解的要求:考生能读懂一般性话题的简短文字材料,例 如公告、说明、广告以及书、报、杂志中的简短文章。考生应能: (1)阅读生词量不超过3%的文段; (2)理解主旨大意; (3)寻找具体信息; (4)识别不同文体特征; (5)根据上下文提供的语境推测生词词义; (6)作出简单的判断和推理; (7)理解文章的基本逻辑结构; (8)把握作者的意图和态度; (9)理解文章的文化信息。 三、 教学目标 1. 知识与技能 A. 训练学生阅读技能; B. 培养学生正确把握阅读理解的出题意图及方向; C. 提高阅读理解的得分率和高效率。 2. 过程与方法 A. 列举法 A. 讲授法 B. 演示法 3. 情感态度与价值观 A. 培养学生的时间观念,合理安排可利用的时间; B. 让学生体验学习的乐趣和成功的喜悦。 四、 教学重、难点 1. 阅读理解的出题方式及方向; 2. 各类阅读理解题型的解题思路; 3. 各类阅读理解题型的实战演练; 五、 教学方法: 1. 合作交流,小组讨论。 2. 自主学习,独立思考。 3. 探究学习。 六、 渗透法制教育 教学步骤: Before class: 先学任务&Warming up: 读下列语段,选出正确答案。 1. As a young girl growing up in the 1930s, I always wanted to fly a plane, but back then it was almost unheard of for a woman to do that. I got a taste of that dream in 2011, when my husband arranged for me to ride in a hot air balloon for my birthday. (2011年高考英语北京A篇) What happened to the author in 2011? A. She flew an airplane. B. She entered a competition. C. She went on a hot air balloon ride. D. She moved into a retirement community. 解析:此题属典型细节题,通过题干中的时间in 2011不难定位到文中粗体字部分,很容易可以锁定正解为C。 2. He longs for conversations with an editor who will help him turn his good ideas into great ones. He wants someone to get excited about what he's doing and to help him turn his story idea upside down and inside out, exploring the best ways to report it. He wants to be more valuable for your paper. (2010年高考英语北京B篇) What does the reporter want most from his editors in their talks? A. Finding the news value of his stories. B. Giving him financial support. C. Helping him to find issues. D. Improving his good ideas. 解析:此题属细节题,定位方式为同义定位法。题干中的talks和文章中conversations对应,而want most和longs for对应,答案为D。 3. She turned up at the doorstep of my house in Cornwall. No way could I have sent her away. No way, not me anyway. Maybe someone had kicked her out of their car the night before. “We're moving house” “No space for her any more with the baby coming.” “We never really wanted her, but what could we have done? She was a present.” People find all sorts of excuses for abandoning an animal. And she was one of the most beautiful dogs I had ever seen. How did the author feel about Goldie when Goldie came to the house? (2010年高考英语北京A篇) A. Shocked. B. Sympathetic. C. Annoyed. D. Upset. 解析:由题目得知:是考察作者的态度题。首先定位到文章作者的话语和行为,即 (1) No way could I have sent her away. No way, not me anyway. (2) We never really wanted her, but what could we have done? She was a present. (3) People find all sorts of excuses for abandoning an animal. And she was one of the most beautiful dogs I had ever seen. 可知作者对它是正的情感,排除C,D.再由作者对它的不舍,答案选B During class: Step1: 阅读理解文章体裁分析 高考英语阅读理解的文章一般有这样几种文体,记叙文、描写文、说明文、应用文和议论文。不同的文体有不同的段落组织方式和脉络层次。 记叙文:往往按时间顺序展开段落,文章有明显表示时间先后的词语。阅读时抓住时间这条主线,弄清who、what、where、why与how。 描写文:通过细节的描写,以画面的方式来反应事物的特征、性质。对这种文章要迅速弄清其主题,主题词往往出现在各个句子里,贯穿文章的始末;紧围绕这个主题进行阅读,找到文章与之有关的信息,并确定信息与主题的关系。 说明文:多见于科普文章,用以解释或揭示事物的状态、特征、演变、结果及其相互之间的关系,这类文体的文章,首句往往是主题句,开门见山,说明文章的关注对象:弄清作者的思路和段落组织的方式;把握次要信息及其与主题的关系。 议论文:阅读难在这种文章处处都渗透作者的个人观点、态度。阅读议论文应该从文体的写作和结构特点入手.文章的结构往往容易把握,主题句开门见山。作者往往通过信号词(signal words或transitional words)和关联词(referents来组织段落、文章,对信号词的迅速反应和对关联词的准确判断是至关重要的;要特别注意区分作者的观点与文章里所提到的人物的观点,同时注意作者所使用的表示赞同、反对等感情色彩的词汇。 Step2: 阅读理解命题方式 (一)细节理解题: 细节类问题的命题方式有以下几种: 1)Which of the following is NOT true according to the information in the passage?(三正一误) 2) The author mentions all of the following except . . . (三正一误) 3)Which of the following statements is correct according to the passage?(三误一正) 4)The writer mentions all of the items listed below except ______.(三正一误) 5) Which of the following is mentioned in the passage? (三误一正) 6) What is the example of . . . as described in the passage? (三误一正) 7) The reason for . . .is . . . (三误一正) 8) According to the passage, when (where, why, how, who, etc. ) ... (三误一正) 9)From the passage we know that ______.(三误一正) 10)In the passage, the author states that ______.(三误一正) 细节理解题就是我们常见的wh-题,它们大多是根据文章中的具体信息如事实、例证、原因、过程、论述等进行提问的。有些问题可以在文章中直接找到答案,有些则要我们在理解的基础上将有关内容系统化才能找到,比如计算、排序、是非判断、图形比较等。做此类题的方法一般是先用寻读法找出与问题相关的词语或句子,再对相关的部分进行细读,找出正确答案。 这种问题的正确选项所包含的信息通常连续出现在同一段,而且往往无列举标志词,如first,second,third等。做题时只需阅读有关段落,根据一个选项中的关键词在其前后找其他选项。 当堂导练一: Invited by Mr. Ye Huixian, host of the well received TV programme “Stars Tonight”,Miss Luo Lin, Miss Asia of 1991,appeared as the guest hostess on the Shanghai TV screen last Sunday. Born in Shanghai and taken to Hong Kong when she was only six years old, Luo Lin has never dreamed of being Miss Asia. Her childhood dream was to be an air hostess. Before she took part in the competition, she had been an airhostess in Cat hay Airline for seven years. However,it still took her three months to learn the art of walking on the stage, dancing, singing, making-up and other proper manners, designed by the Asia TV Station. “It’s really a hard job for me. I won’t enter for such competition any more. Anyhow, I am quite lucky. I am also glad to have had more chance to work for the social welfare since I won the title. This time, in Shanghai, I'd love to make a deep impression on my TV audience, " said Luo Lin with a sweet smile. Q: Which of the following is NOT true? A. Luo Lin is a native of Shanghai. B. Luo Lin moved to Hong Kong with her parents. C. Luo Lin won the title of Miss Asia in 1991. D. Asia TV Station helped Luo Lin to become Miss Asia. 解析: A、C 和D都可在原文找到答案,而B项原文列的是:taken to Hong Kong可判断不是moved to Hong Kong with her parents,因此选B。 (二)主旨大意题 1. 主旨大意题的提问方式有以下几种: 1)The general/main idea of the passage is about ____. 2)Which of the following best states the theme of the passage? 3)In this passage the author discusses primarily ____. 4)The passage is mostly about ____. 5)The passage is mainly concerned about ____. 6)What is the main topic of the passage? 7)What is the best title for the passage? 8)The subject discussed in this text is _____ 9)The author’s main purpose in writing the passage is to … 10)The passage is meant to …. 11)The purpose of this article is to … 2. 在解主题大意题时,可用以下方法: 1)认真阅读文章的第一段或每段的第一个句子。 2)文章的主题作者往往有意识地反复论述。抓住反复出现的中心词,即高频词,也叫做主题词。 3)文章或段落的主题句常常会出现在一些标志性的提示后。 例如:On the whole , in short, therefore… , I agree with the opinion that…, Given all these points above , I would support the idea that…, For all the reasons mentioned above ,I would prefer… 3. 如何寻找主题句 Sample 1 People have different tastes in food. Some feel that they haven't eaten a meal unless they have had steak or other red meat. Some prefer chicken or fish and eat one or the other at every meal. Others prefer vegetables and fruits or grains and would enjoy a meal of spaghetti, eggplant, and fresh fruit. Others could live on what were called fast--foods: a hamburger or hot dog, French fries and a soft drink. (1)主题句在段首:一个主题句常常是一个段落的开头,其后的句子则是论证性细节。在论说文,科技文献和新闻报道中多采用这种格式。 Sample 2 Some students prefer a strict teacher who tells them exactly what to do. Others prefer to be left to work on their own. Still others like a democratic discussion type of class. No one teaching method can be devised to satisfy all students at the same time. (2)主题句也会出现在段尾。作者先摆出事实依据, 层层推理论证, 最后自然得出结论, 即段落的主题。本段的中心思想在结尾句得到体现,它是此段内容的结论。 Sample 3 Nothing is as useful as a flashlight on a dark night if a tire goes flat. Few inventions are so helpful to a child who is afraid of the dark. In fact, the modern flashlight brings light to many dark situations. Finding something in the back of a closet is easy with a flashlight in hand . A camper also needs one after the light of the campfire has been out. (3)在短文中间:当主题句被安排在段中间时, 通常前面只提出问题,文中的主题由随之陈述的细节或合乎逻辑的引申在文中导出, 而后又作进一步的解释, 支撑或发展. (三)推理题 1. 推理题的出题方式常常包括以下类型: 1) It can be inferred from the text that ______. 2) From the text we know that ______. 3) The story implies that ______. 4) The paragraph following the passage will most probably be ___. 5) The writer’s attitude toward...is ______. 6)The author implied(suggested)that... 7)It may be concluded from the passage that... 8)Which of the following statements does the passage support? 9)With which of the following does the author agree? 2. 解推断题应注意: (1)不能以自己的观点代替作者的观点; (2)推理的根据来自于上下文。 3. 解推断题的方法:根据词义关系推断具体细节。 Sample1: “You mean there is no baby who is dying?” said De Vincenzo. “That’s right,” said the official. “That’s the best good news I’ve heard all week.”said De Vincenzo. Q: I t can be inferred that what worried De Vincenzo most was______________. A.the poor woman B.the official’s advice C.the winning check D.the baby’s life 解析:答案D. Sample2: One day a man walked into a pet shop and said to the shop assistant,“I need two small mice and about five dozen roaches (蟑螂) and two spiders.” “What do you need these things for?” the shop assistant was very surprised. “Well,”replied the man,“I’m moving out of my apartment and the landlord insists that I should leave the house in exactly the same condition as I found it.” Q: The passage suggests that when the writer moved into the house, it was ______. A. very clean B. just cleaned by the landlord C. tidy and comfortable D. dirty and full of insects 解析:他要搬出所租的房子,而房东要求房屋必须是他租进来时的原样,所以他须买些老鼠和蟑螂等昆虫对房屋进行“恢复”,因此推出答案为D。 (四)观点态度题 1. 考查作者观点态度的提问方式有: 1)The author seems to think that ______. 2)The writer is trying to present a point of view in ______. 3)The author wants to appeal to _______ . 4)The author’s style is ______ . 5)The author’s tone would be best described as _______ . 6)What is the author’s opinion of ______? 7)The writer believes that________? 8) In the author's opinion_________? 2. 确定作者态度,可以有两种思路: 1)问全文主体事物的(包括主题),可以根据阐述主题或有关主体事物的相关句中的形容词、副词或动词确定作者的态度; 2)如果问的是对某一具体事物的态度,则可以定位到具体相关句,然后确定答案。 Sample 1 Some people are never right. They never have good luck. They usually do the wrong thing and say the wrong thing. And even if what they say or do is OK,they as a rule say it or do it at the wrong time. So these people always have problems. They often break dishes. They sometimes miss buses and airplanes. Mr. Neff is different. He is always right. He is never wrong. He usually has good luck. He seldom has problems. He never breaks dishes. He never misses buses or airplanes. Even if he does miss them,it is always the fault of the buses or air planes. Mr. Neff knows almost everything. He doesn’t ask questions;he answers questions. He never says,“I don’t know.” Q: Which of the following best describes the writer’s attitude to Mr. Neff? A. He finds Mr. Neff hard to understand.B. He thinks Mr. Neff wonderful. C. He feels pity for Mr. Neff. D. He does not like Mr. Neff. 解析:从作者的语气中我们可以体会他的态度,特别是Even if he does miss them,it is always the fault of the buses or the airplanes. 误了车或飞机本该是人的失误怎能归咎于车或飞机呢?明显是讥讽,也是暗示他对Mr. Neff的讨厌之情。答案为D。 (五)判断词义题 1. 如何根据上下文判断词语的含义这种题型常见的设题方式有: 1)The underlined word(phrase)in the passage means ____. 2)The word "it(them)"in the first paragraph refers to ____. 3)The underlined sentence in the last paragraph means ____. 4)Which of the following is closest in meaning to the underlined word in the second paragraph? 2. 猜词方法 1)根据常识、经验猜生词 。例如: The old man put on his spectacles and began to read. (glasses) The door was so low that I hit the head on the lintel.(过梁) 2)根据上下文解释做出判断:其方法主要有: (1)根据文中的定义、解释猜生词 。例如: Skimming means looking over a passage quickly to get the main idea before you begin to read it carefully.(略读) The harbor is protected by a jetty—a wall built out into the water.(码头) (2)利用事例或解释猜生词 。例如: The doctor is studying glaucoma and other diseases of the eye.(青光眼) (3)利用重复解释的信息猜生词 。例如: Mr. Smith always arrives home punctually,neither early nor late.(准时的) (4)根据同位关系进行判断: 阅读中出现一些难词,有时后面就是一个同位语,对前面的词进行解释,这种解释有时也用连词“or”连接。 a)...,and other Germanic and Nordic peoples,who spoke what we now call Anglo-Saxon(or Old English),a Germanic language. (盎格鲁撒克逊语) b)The "Chunnel",a tunnel(隧道)connecting England and France,is now complete. 3)利用标点符号和提示词猜测词义 One of the obstacles to false reading is vocalizing—saying the words to themselves in a low voice.(发声) The early scientific study of chemistry,known as alchemy,grew up in Egypt in the first few centuries A.D. (炼金术) 4)根据上下文的指代关系进行选择 文章中的代词it,that,he,him或them可以指上文提到的人或物,其中it和that还可以指一件事。有时代词指代的对象相隔较远,要认真查找;也有时需要对前面提到的内容进行总结,才能得出代词所指代的事。 5)根据转折或对比关系进行判断 根据上下句的连接词,如:but,however,otherwise等就可以看到前后句在意义上的差别,从而依据某一句的含义,来确定另一句的含义。分号(;)还可以表示转折、对比或不相干的意义。 He has been getting better,but during the night his condition deteriorated.(恶化) 6) 根据因果关系进行判断 根据原因可以预测结果,根据结果也可以找出原因。 Biggest power failure in the city's history… All of our ice-cream and frozen foods melted.(融化) 后一句承接前一句,前一句的原因导致后一句的结果。根据因果关系,停电很可能导致冰淇淋和冷冻食品溶化,所以melted的词义应为"溶化"。 7)根据构词法(合成、派生、转化)进行判断 英语中,有很多词可以在前面加前缀,后面加后缀,从而构成一个词,乍看起来,这个词可能是生词,但掌握了一定的构词法知识,就不难猜出它的词义。 例如:Market research shows that Gold and others who buy organic food can generally give clear reasons for their preferences--but their knowledge of organic food is far from complete. (偏爱;爱好) 我们知道,prefer的意思是"宁愿;愿意",根据上下文可以判断prefer的名词形式preference的含义应是"偏爱;爱好"。 Step3: 猜答案方法 1. 绝对词否决法, 答案项中有绝对语气词的一般不是正确答案项。这些语气词有: must, always, never, the most, all, only, have to, any, no, very, completely, none, hardly等。 A. She can’t attend her nephew’s wedding party. B. She values the bowl from her mother a lot. C. She is living alone near an art gallery. D. She doesn’t care about money any more. not any more是绝对词,D 答案是错误选项。 2. 怀疑词判断法:选项中含有不十分肯定的语气词一般是正确答案项。这些语气词有can, could, may, should, usually, might, most(大多数), more or less, relatively, be likely to, possible, whether or, not necessarily 等。 A. zoo elephants suffer less stress than those in the wild. B. elephants are quite easy to get obese. C. social lives are not important to elephant. D. zoo life can be stressful to elephant. D答案正确。 3. 关键词对应法 (ABC=ABC法; ABC=A’B’C’法; ABC=CBA法; ABC≠ABD法) 4. 选项的全面性判断法 较全面、有针对性地表达文章中心思想的,选项一般是答案项。 A. to be more successful in his career B. to solve technical problems C. to be more specialized in his field D. to develop his professional skill B“解决技术问题”;C“深化专业”;D“发展职业技能”。这三项表达的意思都比较具体,而A项则概括地有深度,包括了B、C、D三项内容。选项中表达意义较具体的、肤浅的(字面意思)一般不是答案项,而概括性的、抽象的、含义深刻的是答案项。 Step4: 长、难句分析法 Sample: Twenty students had just climbed their way to the top rung (最高的台阶) out of four million students taking part in the Fifth National Hua Luogeng Gold Cup Mathematics Contest on Tuesday evening at Jintan County, Jiangsu Province. 1. 分析过程: 句子的核心:students...climbed...way 句子的一系列细节: How many:twenty out of four million What result: to the top rung What thing: the Fifth National Hua Luogeng Gold Cup Mathematics Contest Doing what: taking part in the... Contest When: Tuesday evening Where: Jintan County, Jiangsu Province 抓住句子的核心后,我们首先准确地理解了句子最主要的成分:……学生登上最高的台阶。再经过对这个长句的一系列细节的分析,我们可以更进一步地了解到:四百多万参加“全国第五届华罗庚数学金杯赛”中的中学生里有二十个学生在星期二于江苏省金坛县登上了最高的台阶。 2.找出谓语动词是抓住核心的关键 找出句子的谓语动词后,用who或what放在谓语动词前发问,就可以轻而易举地找到主语,然后再用whom或what发问,就可迅速找出其宾语或表语,以及一系列状语,这样正确理解长句或难句就会变得轻松而容易。请看下面例证中的划线的句子: Sometimes an animal has a plant partner. The relationship develops until the two partners cannot manage without each other. This is so in corals(珊瑚) of the sea. In their skins, corals have tiny plants which act as "dustmen", taking some of the waste products from the coral and giving in return oxygen which the animal needs very much to breathe. 乍看划线的这个句子,第一印象是这个句子很长,再看下去,就会感到这个长句中动词很多,多至六个。那么哪一个是谓语动词呢?根据我们已掌握的基本知识,经过语法分析,不难看出这个句子的谓语动词是have。于是我们用what放在have前提问:What have...?回答这个问题的过程就是找出主语的过程:corals have..., 然后再用what放在谓语动词后发问:corals have what?找出这个问题的答案也就找到了这个谓语动词have的宾语:have tiny plants。这样该句的最核心的部分:主语、谓语和宾语就都准确地找到了。 3.语法分析法是准确理解细节的有效方法 在上例划线的句首处,用了介词词组:in their skins(在它们的皮肤上),交代了corals have tiny plants的地点状语,实际上回答的是where(何处)的问题;在plants之后用的是限制性的定语从句:which act as“dustmen”(起到是清洁工作用的微生物),实际上回答的是what effect do they have(它们起的是什么作用)的问题。在这个定语从句后出现的是现在分词短语:taking some of the wasted products from the coral and giving in return oxygen...。经过语法分析,不难看出此处的分词短语起的是解释说明的作用,其意为:从珊瑚中清理掉一些废料的产物而归还其氧气。在oxygen之后又出现了一个定语从句:which the animal needs very much to breathe(此种动物非常需要呼吸的氧气)。正确理解是:在珊瑚的皮肤中,有着一些微生物,这些微生物在它们身体上充当着“清洁工”,清理掉它们身体产生的废料,而还给珊瑚这种动物非常需要呼吸的氧气。 当堂导练二: 1. 主旨大意题: Federal regulators Wednesday approved a plan to create a nationwide emergency alert (警报) system using text messages delivered to cell phones. Text messages have been popular in recent years, particularly among young people. The wireless industry's trade association, CTIA, estimates(估计) more than 48 billion text messages are sent each month. The plan comes from the Warning Alert and Response Network Act, a 2006 federal law that requires improvements to the nation's emergency alert system. The act tasked the Federal Communications Commission (FCC) with coming up with new ways to alert the public about emergencies. “The ability to deliver accurate and timely warnings and alerts through cell phones and other mobile services is an important next step in our efforts to help ensure that the American public has the information they need to take action to protect themselves and their families before, and during, disasters and other emergencies,” FCC Chairman Kevin Martin said, following approval of the plan. Participation in the alert system by carriers -telecommunications companies is voluntary, but it has received support from the wireless industry. The program would be optional for cell phone users. They also may not be charged for receiving alerts. There would be three different types of messages, according to the rules. The first would be a national alert from the president, likely involving a natural disaster. The second would involve “approaching threats”, which could include natural disasters like hurricanes or storms or even university shootings. The third would be for child abduction (绑架) emergencies, or so-called Amber Alerts. The service could be in place by 2010.( 2008年高考英语山东卷B篇) 66. Which of the following would be the best title for the text? A. Cell Phone Alerts Protecting Students B. Cell Phone Alerts by Wireless Industry C. Cell Phone Alerts of National Disasters D. Cell Phone Alerts Coming Soon 答案:D 2. 猜测词义题 Weeks later, standing before this unfriendly mass, I was totally lost. Oh well, I lowered the paper and sat down at my desk, burning to find out what I had done wrong. As a classmate began his report, it all became clear, “My report is on George Washington, the man who started the American Revolution.” The whole world became quite! How could I know that she meant that George Washington? 62. The underlined word “burning” in Para. 3 probably means _______.(2012年北京,B篇,62,答案D) A. annoyed B. ashamed C. ready D. eager 解析:从burning这个词来说,意为“发热的,强烈的,燃烧的”,后面紧跟动词词组“find out”说明在寻找时刻的心情是很紧张和急迫的,最后是一个宾语从句,是我曾经做错过什么,那么这个题目显然就是选择和“渴望的,热切的”词义,显然为D选项。 3. 细节理解题 Life on Land Life on land probably began about 430 million years ago, though it has existed in the water for perhaps as long as 3000 million years. When we think of the first life on land, we probably think of strange animals coming out of the oceans, but, in fact ,no animals could have been living if plants had not been on land first. Plants had to be on land before animals arrived. They supplied the first land animals with the surrounding and food necessary, since they--the plants are the only form of life that is able to get and store energy. The first plants to exist out of the water were probably certain kinds of algae (海藻) which were followed by other plants that grew close to the ground and needed water in which to reproduce. Which of the following is TRUE? A. Algae have existed for more than 430 million years. B. It is impossible that algae might be the earliest plant on land. C. Plants get food from animals in the oceans. D. Evolution began after animals appeared on land. 这是一道事实询问题。需要把短文第一段首句“Life on land probably began about 430 million years ago”和短文第二段首句“The first plants to exist out of the water were probably certain kinds of algae”联系起来考虑,正确答案为A。 After class: Step5: 自辅落实 Try to finish two reading passages using the reading skills you have learnt.
