小学一年级语文期中、期末试卷分析

小学一年级语文期中、期末试卷分析

小学一年级语文期中、期末试卷分析1.小学一年级语文期中试卷分析第一项:把学过的声母按顺序写下来本题大部分同学书写正确。

但个别人声母韵母不分家,都写上了。

今天我找部分同学问了问,他们告诉我,他们不认识要求的字,不知些什么,所以声母韵母都写上了。

改正措施:每周抽出一节语文课,多练习有关拼音的考察项目。

一是让学生认识要求,二是巩固复习拼音。

第三项:找朋友该项许多学生不知道让他干什么?不知道两边拼音与中间词语连起来。

也有一部分同学对拼音不熟,拼不出正确的音节,所以连错。

改正措施:平日上课多注重拼读方面训练。

第六项:背一背,写一写。

除了我没学的,其他内容同学都背下来了,只是填的有错。

原因(1)大部分学生不会写字。

(2)不知道填空多少单词。

改正措施:今后在课堂内多知道该项训练。

第四项,第五项,第七项有些内容我们还没有上到。

改正措施:今后准备加快上课效率,赶上进度。

第八项:根据所学儿歌内容进行连接。

丢分的原因是学生的素养太小。

改正措施:今后引导学生加大识字量,阅读课鼓励学生多读书,多识字。

并每次评出优胜者。

总之,今后要想尽一切办法扩大学生的识字量,多出卷子,让学生认识试卷。

另方面努力提高课堂效率,把学生的成绩提上去。

期终检测取得好的成绩。

2.小学一年级语文期中试卷分析一、考试概况全年级12人,12人参加考试。

考试时间60分钟,试卷总分100分。

绝大多数中国学生都能在规定时间内完成题目,卷子整洁。

二、试题分析本次期中考试,内容大多是平时练过、做过的题型,主要检测学生对汉语拼音、基本笔画、所学汉字的掌握情况。

试题总的来说比较简单。

从学生答卷来看,90%以上的学生字迹工整,书写规范,卷面干净。

这说明教师在平时教学中很注意引导学生培养良好的学习习惯。

从答题情况来看,学生的基础知识学得比较扎实。

大多语文生较熟练地掌握了汉语拼音,认识了一些基本笔画,对所学的生字能做到会读、会写、会用。

但由于一年级小学生第一次考试,所以出现了不少的问题,具体分析如下:1、第一题:我会背写单韵母。

While everyone has an age based on their date of birth - “chronological age”, they also have 41 is known as a “biological age”, based on the ageing of the body’s functions, influenced by genetics, lifestyle and other factors. Studies have previously suggested the higher the biological age, the higher the risk of various diseases, and the risk of death. Now researchers say they have created a digital model of ageing, 42 (reveal) the importance of psychological health. “Your body and s oul are connected, 43 is our main message,” said Fedor Galkin, a co-author of the study and lead scientist at the Hong Kong startup Deep Longevity.“We demonstrate that psychological factors, such as feeling unhappy or being lonely, add up to 1.65 years to one’s biological age,” they write. While Galkin said the figure is an estimate, not least as the model assumes that different feelings like hopelessness or fearfulness are independent of each other, the study highlights that 44 fast we age is significantly associated with our psychological state.“Taking care of your psychological health is the greatest contributor that you can have to 45 (slow) down your pace of ageing,” he said. The team also report that people who smoke 46 (predict) to be 15 months older than their non-smoking peers while living in urban areas reduces biological age 47 five months. Similarly, 48 (marry) takes about seven months off one’s biological age.But, he said, it is unlikely isolation and loneliness are truly worse risk factors for health than smoking, while the study only looked at the data that 49 (collect) at one point in time. “The researchers did not follow up participants to show that those with psychological distress actually aged more rapidly,” he said. “It will be important in the future 50 (test)whether these predictions can be fulfilled by repeating testing over a number of years.”Directions: Fill in each blank with a proper word chosen from the box.

But in the age of COVID-19, many passengers are 51 less inclined to remove their masks to take a mid-flight bite ― or to even have a snack at the airport.As a result, it’s more common to eat at home before e mbarking on a flight. Those with longer travel journeys may even eat a large meal to carry them through the day. Still, not all preflight eats are created 52 .Tracy Lockwood Beckerman, a registered dietitian based in New York City, said it’s worthconsid ering your overall health as you prep for travel, including what you eat and drink. “It’s important to eat foods that will keep your immune system strong, keep you hydrated and are easily digested before flying,” Beckerman said.So, which foods are best 53 on a day when you’re traveling by plane?“It’s super common for dehydration to set in when flying, thanks to the lack of humidity and dry air in the 54 ,” Beckerman said. “That’s why it’s not the smartest to have a meal high in sodium (钠) the day bef ore or morning of your flight.” Beckerman also advised going easy on the salt shaker, opting for snacks without added salt to avoid dehydration-related headaches.Alcohol consumption tends to cause dehydration and has a different effect on the body than if you were to have a drink at ground level due to the low pressure in the cabin and the low oxygen 55 in blood. Therefore you are more likely to get drunk faster and urinate frequently.A cup of coffee can leave you dehydrated in an already dry environment and coffee also has a mild diuretic effect, which can lead to more frequent trips to the bathroom.Beyond the dehydrating effects, caffeine can also keep you awake during a flight, which is often an opportunity to catch up on sleep. The need for more frequent bathroom visits can also 56 with your ability to doze during your travels.If you have a sensitive stomach, you might want to 57 clear of foods that can mess with your digestion. That includes highly 58 snacks like candy and fast food, which often contain ingredients that could 59 your digestive system.A balanced meal that satisfies your 60 with water and hydrating fruits contains moderate amounts of complex carbohydrates and lean protein, and is low in added sugars and sodium is ideal.AI can transform education for the betterAs students return to classrooms for the new year, it is striking to reflect on how little education has changed in recent decades. The sector remains a digital laggard (落后者). American schools and universities spend 2% and 5% of their budgets, _________, on technology, compared with 8% for the average American company.When the pandemic forced schools and universities to shut down, the moment for a digital_________ seemed close when the market value of online tutoring providers like Chegg and Byju’s both increased. However, once covid was brought under control, classes continued much as before. If the pandemic couldn’t overcome the education sector’s _________ to d igital interruption, can artificial intelligence? ChatGPT-like generative AI, which can converse cleverly on varieties of subjects, certainly _________. So much so that educationalists began to _________ that students would use it to cheat on essays and homework. Increasingly, however, it is generating excitement as a means to provide _________ tutoring to various students and speed up boring tasks such as marking.Learners, for their part, are _________ the technology. Two-fifths of undergraduates reported using an AI chatbot to help them with their studies. Indeed, the technology’s popularity has raised awkward questions for companies like Chegg, which was losing customers _________ ChatGPT. Yet there are good reasons to believe that education specialists like Chegg who employ AI will eventually _________ generalists such as OpenAI, the maker of ChatGPT.For one, AI chatbots often talk nonsense, an unhelpful trait in an educational context. “Students want content from __________ providers,” argues Kate Edw ards, chief pedagogist at Pearson, a textbook publisher. The company has not allowed ChatGPT and other AIs to __________ its material, but has instead used the content to train its own models, which it is embedding into its set of learning apps.__________, as Chegg’s Mr Rosensweig argues, teaching is not merely about giving students an answer, but about presenting it in a way that helps them learn. Understanding pedagogy (教学法) thus gives education specialists an __________. Pearson has designed its AI tools to __________ students by breaking complex topics down, testing their understanding and providing quick feedback, says Ms Edwards. Byju’s is incorporating “forgetting curves” for students into the design of its AI tutoring tools, refreshing their memories at personalized __________.Bringing AI to education will not be easy, but once answers on how to make use of this technology become clearer, such a development will certainly deserve top marks.61.A.respectively B.appropriately C.totally D.ultimately62.A.divide B.reverse C.boom D.withdrawal 63.A.tendency B.resistance C.attention D.anxiety64.B.break the ice C.take the initiative D.do some good A.serve thepurpose65.A.maintain B.panic C.doubt D.wonder66.A.personalized B.individualistic C.characteristic D.attentive 67.A.attempting B.declining C.opposing D.embracing 68.A.for B.under C.to D.in69.A.detect B.transform C.overtake D.enhance 70.A.comprehensive B.advanced C.distinguished D.trusted71.A.give away B.take in C.bring about D.hold up72.A.By contrast B.Despite this C.What’s more D.As a result 73.A.applause B.edge C.hesitation D.improvement 74.A.convince B.engage C.capture D.challenge 75.A.intervals B.cost C.mercy D.bestThe train was at a standstill, some twenty minutes outside Kolkata, when an unexpected stroke of luck presented Piya with an opportunity to go for a seat beside a window for some fresh air. She had been sitting in the stuffiest part of the train compartment, on the edge of a bench: now, moving to the open window, she saw that the train had stopped at a station called Champahati.Looking over her shoulder, Piya spotted a tea-seller on the platform. Reaching through the bars of the window, she called him with a wave. She had never cared for the kind of chai, Indian tea, sold in Seattle, her hometown in the USA, but somehow, in the ten days she had spent in India she had developed an unexpected taste for milky, overboiled tea served in earthenware cups. There were no spices in it for one thing, and this was more to her taste than the chai at home.She paid for her tea and was trying to get in the cup through the bars when the man in the seat opposite her own suddenly turned over a page, jolting her hand. She turned her wrist quickly enough to make sure that most of the tea spilled out of the window, but she could not prevent some from spilling over his papers.“Oh, I’m so sorry!” Piya was very embarrassed: of everyone in the compartment, this was the last person she would have chosen to injure with her tea. She had noticed him while waiting on the platform in Kolkata and she had been struck by the self-satisfied tilt of his head and the way in which he stared at everyone around him, taking them in, sizing them up, sorting them all into their places.“Here,” said Piya, producing a handful of tissues. “Let me help you clean up.”“There’s nothing to be done,” he said testily (暴躁地). “These pages are ruined anyway.”For a moment she considered pointing out that it was he who had knocked her hand. But all she could bring herself to say was, “I’m very sorry. I hope you’ll excuse me.”“Do I really have a choice?” he said. “Does anyone have a choice when they’re dealing with Americans these days?”Piya had no wish to get into an argument so she let this pass. Instead, she opened her eyes wide and, in an attempt to restore peace, came out with, “But how did you guess?”“About what?”“About my being American? You’re very observant.”This seemed to do the trick. His shoulders relaxed as he leane d back in his seat. “I didn’t guess,” he said. “I knew.”76. In the first paragraph, Piya was relieved when she got a window seat because it meantthat_________.A.there was more room for her luggageB.she no longer had to suffer from a lack of airC.there was less chance that she would miss her stopD.she didn’t have to stand for the rest of the train journey77. Piya found that the tea or chai she had drunk in India ________.A.was disappointingly weak in taste B.reminded her of her home in SeattleC.would have tasted better if served fresh D.was preferable to the chai she had hadbefore78. When Piya first saw the man she thought that ________.A.he was someone who was observant of surroundingsB.he seemed to think he was better than other peopleC.he had tried to keep his distance from his fellow passengersD.he had been looking for someone he knew on the station platform79. Piya asked “But how did you guess?” in order to _________.A.find out what the man really thought about AmericansB.try to calm the situation down by starting a conversationC.ensure the man realized that she had apologizedD.make sure the man knew he was being rudeOur library offers different types of studying places and provides a good studying environment.ZonesThe library is divided into different zones.

The decisions made it more difficult for states to collect sales tax on certain online purchases.The cases the court overturned said that if a business was shipping a customer’s purchase to a state where the business didn’t have a physical presence such as a warehouse or office, the business didn’t have to collect sales tax for the state. Customers were generally responsible for paying the sales tax to the state themselves if they weren’t charged it, but most didn’t realize they owed it and few paid. Justice Anthony Kennedy wrote that the previous decisions were flawed. “Eac h year the physical presence rule becomes further removed from economic reality and results in significant revenue losses to the States,” he wrote in an opinion joined by four other justices. Kennedy wrote that the rule “limited States’ ability to seek lon g-term prosperity and has prevented market participants from competing on an even playing field.”The ruling is a victory for big chains with a presence in many states, since they usually collect sales tax on online purchases already. Now, rivals will be c harging sales tax where they hadn’t before. Big chains have been collecting sales tax nationwide because they typically have physical stores in whatever state a purchase is being shipped to. , with its network of warehouses, alsocollects sales tax in every state that charges it, though third-party sellers who use the site don’t have to.Until now, many sellers that have a physical presence in only a single state or a few states have been able to avoid charging sales taxes when they ship to addresses outside those states. Sellers that use eBay and Etsy, which provide platforms for smaller sellers, also haven’t been collecting sales tax nationwide. Under the ruling Thursday, states can pass laws requiring out-of-state sellers to collect the state’s sales tax from customers and send it to the state.Retail trade groups praised the ruling, saying it levels the playing field for local and online businesses. The losers, said retail analyst Neil Saunders, are online-only retailers, especially smaller ones. Those retailers may face headaches complying with various state sales tax laws. The Small Business & Entrepreneurship Council advocacy group said in a statement, “Small businesses and internet entrepreneurs are not well served at all by this decision.”83. The Supreme Court decision Thursday will ______.A.better businesses’ relations with statesB.put most online businesses in a dilemmaC.make more online shoppers pay sales taxD.force some states to cut sales tax84. It can be learned from paragraphs 2 and 3 that the overruled decisions ______.A.have led to the dominance of e-commerceB.have cost consumers a lot over the yearsC.were widely criticized by online purchasersD.were considered unfavorable by states85. According to Justice Anthony Kennedy, the physical presence rule has ______.A.hindered economic development B.brought prosperity to the countryC.harmed fair market competition D.boosted growth in states revenue86. In dealing with the Supreme Court decision Thursday, the author ______.A.gives a factual account of it and discusses its consequencesB.describes the long and complicated process of its makingC.presents its main points with conflicting views on themD.cites some cases related to it and analyzes their implicationsTwilight of the BrandsIt's a truism of business-book thinking that a company's brand is its "most important asset," more valuable than technology or patents or manufacturing prowess.But brands have never been more fragile.The reason is simple: consumers are supremely well informed and far more likely to investigate the real value of products than to rely on logos.Absolute Value, a new book by Itamar Simonson and Emanuel Rosen shows that, historically, the rise of brands was a response to an information-poor environment. 87 If a car was made by G.M, or a ketchup by Heinz, you assumed that it was pretty good.It was hard to figure out if a new product from an unfamiliar company was reliable or not, so brand loyalty was a way of reducing risk.Today, consumers can read much research about whatever they want to buy.This started back with Consumer Reports, which did objective studies of products. 88 It has given ordinary consumers easy access to expert reviews, user reviews, and detailed product data, in an array of categories.A recent study found that eighty per cent of consumers look at online reviews before making major purchases, and a host of studies have logged the strong influence those reviews have on the decisions people make. 89 An undesirable product can become a laughingstock(笑柄) in a matter of hours.In the old days, you might buy a Sony television set because you'd owned one before, or because you trusted the brand.Today, such considerations matter much less than reviews on Amazon and Engadget and CNET. As Simonson said, "each product how has to prove itself on its own."It's been argued that in a world where consumers are overwhelmed with information, the information will actually make brands more valuable.Indeed, the role a brand plays in people's lives has become all the more important, But information overload is largely a myth. 90 And this has made customer loyalty pretty much a thing of the past.Only twenty-five per cent of American respondents in a recent study said that brand loyalty affected how they shopped.91. 你越多练习武术,你就越能理解为什么它是一个值得传承的国之瑰宝。
