《幼儿卫生学》参考答案主题1 幼儿结构生理特点一、单项选择题：1. A2. D3. A4. C5. B6. A7. C8. A 9．B 10．C二、判断题：1. ×2. ×3. √4.×5. √6. ×7.√8. ×9.√ 10.√三、案例分析：1．答案：因龋齿而导致孩子心理自卑。

牙齿是人体最坚硬的器官，可切断、撕裂和磨碎食物，还有辅助发音的功能。

从结构上牙由牙本质、釉质、牙骨质和牙髓组成。

牙本质是构成牙齿最主要的物质，颜色淡黄而有光泽，硬度较牙釉质低，牙本质中有神经末梢，受到刺激时有酸痛感；釉质覆盖在牙冠的最外层，是人体中最硬的一种组织；牙骨质是被盖在牙根外层的组织；牙中央的空腔称为牙腔或牙髓腔，内有牙髓。

乳牙因牙釉质薄，牙本质松脆，易生龋齿。

因此要保持口腔卫生。

2016年6月大学英语四级考试真题（第2套）参考答案Part I WritingDear My Parents,I would like to convey in this letter my heartfelt thanks to you. Without your support and encouragement, I wouldn’t have won the second prize in the National Mathematical Contest in Modeling.First of all, you inspired me to participate in the contest and gave me the confidence that I could achieve a good result if I worked hard enough. In addition, you spent large sums of money on prestigious mathematical modeling teachers to help me with methods of mathematical modeling, thesis writing and computer programming, which laid a solid foundation for my outstanding performance in the contest. Finally, it is also worth mentioning that when I was downhearted in the face of difficulties and setbacks during the contest, it was you who raised me up to press forward.All in all, your support in both spiritual and material terms made it possible for me to win a prize in the contest. So, thanks again for your kind help. I am looking forward to seeing you soon.Affectionately yours,Li MingPart IV TranslationChinese martial art is commonly known as Kung Fu.

It is one of the Chinese traditional sports, which is practiced by both the young and the old. It has gradually evolved into the unique element of Chinese culture. As China’s national treasure, Kung Fu has hundreds ofdifferent styles and is the most practiced martial arts from in the world. Some styles imitate animals’ movements, while others are inspired by Chinese philosophies, myths and legends.Part II Listening Comprehension 听力原文Section AQuestions 1 and 2 are based on the news report you have just heard.The International Labor Organization says the number of people without jobs is increasing. In its latest update on Global Employment Trends, the agency says projections of the number of unemployed people this year range from 210 million to nearly 240 million people. The report warns that 200 million poor workers are at risk of joining the ranks of people living on less than two dollars per day in the past three years. The Director-General of the International Labor Organization Juan Somavia notes that some countries have taken measures to address the effects of the global crisis. However, he points out that many countries have not done so. And based on past experiences, it takes four to five years after economic recovery for unemployment to return to pre-crisis levels. Mr. Somavia says the International Labor Organization is proposing a global job’s agreement to deal with unemployment.“Its key objective is to place so the center of recovery efforts, measures that would generate high levels of employment and provide basic social protection for the most vulnerable.”1. What is the news report mainly about?2. What does Juan Somavia, the Director-General of the International Labor Organization say?Questions 3 and 4 are based on the news report you have just heard.Big fast food chains in New York City have started to obey a first-of-its-kind rule requiring them to post calorie counts right on the menu. Cathy Nurses is with the New York City Department of Health.“We wanted to give people an opportunity to actually see the calories before they purchase the food and make a decision, an informed decision that if they want to make the healthier choice, if they want to eat fewer calories, they can. And we expect this will have a huge impact on obesity. And of course, if it has an impact on obesity, it will have an impact on diabetes and heart disease and high blood pressure.”The new rules will introduce as a part of anti-obesity campaign that also includes a recent citywide ban and artificial trans-fats in restaurant food. The menu rule only applies to restaurants that serve standardized portion sizes and have fifteen or more locations nationwide.Starting last Saturday, chains big enough to fall under the rule will face penalties about 2000 dollars for not showing calorie information in a prominent spot on their menus, preferably next to the price.3. What are big fast food chains in New York City required to do according to the new rule?4. What will happen to big restaurant chains that violate the new rule?Questions 5 to 7 are based on the news report you have just heard.Almost all companies recognize the importance of innovation today. But not many are able to integrate innovation into their business. A commentary in the Shanghai Daily points out that innovation doesn’t mean piles of documents. It is something more practical. The article says many people tend to assume that innovation just means creating something new, but actually it's more than that. It's an attitude of doing things. A company should find ways to innovate not just in products but also in functions, business models and processes.The article cites the global giant Procter & Gamble as an example, saying a real innovative company should develop an innovation culture and use it as a primary tool for success. Procter & Gamble has a “Corporate Innovation Fund” which offers big rewards for high-risk ideas that succeed. It also has a special innovation facility for its employees. Sometimes its employees are released from their daily jobs for weeks and spend their time interacting in the innovation facility instead. In conclusion, the article says innovative ideas alone do not ensure success. It’s pointless unless there is a repeatable process in place to turn inspiration into financial performance.5. What is the problem with many companies according to the news report?6. What do many people tend to think of innovation?7. What does the company Procter & Gamble owe its success to?Section BQuestions 8 to 11 are based on the conversation you have just heard.M: So, Lyndsay, do you like to text message on your cell phone?W: Yeah, I text message a lot.M: I don't do it so much. I prefer to make a call if I'm in a hurry.W: Yeah, I go both ways. Sometimes I don’t really want to talk to the person. I just want to ask them one question, so it's much easier for me just to text message. If I call them, I'll have to have a long conversation.M: Yeah, I can see what you mean. But I get off the phone pretty quickly when I call. I'm not a big talker.W: Yeah, that's true. You don't talk a lot.M: So are you fast at writing the messages with your thumb?W: Well, when I first got a cell phone, I was so slow. I thought I would never text message. But then people kept text messaging me, so I felt obliged to learn how to text message. So now I'm pretty fast. What about you?M: Actually I have the opposite problem. When I first got my cell phone, I thought it was so cool to text message all my friends who have one, and I was pretty fast with my thumb then. But it seems like now I don't use it so much, I've got slower actually.W: Yeah, I think text messaging actually is what you have to do with your age. For example, people in high school, they text message a lot. But I ask my father if he texted messages, and guess what he said?M: What?W: He said he'd never text message. He thinks it's very childish and unprofessional to text message.M: Yeah, I can see what he means. It's considered pretty informal to text message someone.8: What does the man say about himself?9: What does the woman tend to do while she is on the phone?10: Why did the man text message all his friends when he first got his cell phone?11: What does the woman's father think of text messaging?Questions 12 to 15 are based on the conversation you have just heard.W: Good morning, Mr. Johnson. How can I help you?M: Well, I'd like to talk to you about Tim Bond, the department manager.W: What seems to be the problem?M: Well, ever since Sandra left the department, I feel like I've been targeted to do all her work as well as mine. I'm expected to attend too many meetings and I seem to be spending a lot of my time doing unnecessary paper work.W: I'm sorry to hear that.M: And, on top of that, I'd specifically asked if I could leave early last Friday as I’d done a lot of overtime during the week. But that afternoon, even though I'd finished my assigned work, I was told to help other colleagues finish their work, too.W: But surely that's a positive sign showing that Mr. Bond has a lot of trust in you.M: Yes, but other colleagues get to leave early, and they don't have such a lot of work to do.W: So you feel he's been making unrealistic demands on you?M: Yes, absolutely.W: Have you approached Mr. Bond about this particular problem?M: I've tried, but it seems like he just has no time for me.W: Well, at this stage, it would be better if you approached him directly. If nothing else, showing that you've tried to solve the problem yourself, before you take it further, makes it clear that you're just not a complainer. Why don't you send an email requesting a meeting with him in private?M: Hmm, I’d be a bit worried about his reaction. But anyway I'll send him an email to request a meeting, and I'll see what happens from there. Thanks for your advice.W: Good luck. And let us know the outcome.12. What do we learn about the man from the conversation?13. What is the man's chief complaint?14. How does the woman interpret the fact that the man was asked to help his colleagues with their work?15. What did the woman advise the man to do?Section CQuestions 16 to 18 are based on the passage you have just heard.The massive decline in sleep happened so slowly and quietly that few seemed to notice the trend. Was it because of the growing attraction of the Internet, video games and endless TV channels? Never disconnecting from work? No matter how it happened, millions of Americans are putting their health, quality of life and even length of life in danger.New evidence shows why getting enough sleep is a top priority. Some 40% of Americans get less than 7 hours of shut-eye on weeknights. "The link between sleep and health, and bad sleep and disease is becoming clearer and clearer," says Lawrence Epstein, a sleep expert at Harvard University. For example, sleep duration has declined from some 8 hours in the 1950s to 7 in recent years. At the same time, high blood pressure has become an increasing problem. Blood pressure and heart rate are typically at their lowest levels during sleep. People who sleep less tend to have higher blood pressure, heart attack, diabetes, weight gain and other problems.Sleeping better may help fight off illness. "When people are sleep-deprived, there are higher levels of stress hormones in their bodies which can decrease immune function." says Doctor Felice, of Northwestern University in Chicago. A university of Chicago study shows people who sleep well live longer. So say good night sooner and it may help you stay active and vital to a ripe old age.16. What is the speaker mainly talking about?17. What do we learn from the talk about today's Americans?18. What does the speaker say will happen to people who lack sleep?Questions 19 to 21 are based on the passage you have just heard.Parents and teachers will tell you not to worry when applying for a place at a university. But in the same breath we’ll remind you that it is the most important decision of your life.The first decision is your choice of course. It will depend on what you want to get out of university, what you are good at and what you enjoy. The next decision is where to apply. Aim high but within reason. Do you have the right combination of subjects and are your expected grades likely to meet entry requirements? The deadline is January 15th. But it is best to submit your application early because universities begin work as soon as forms start rolling in.The most important part of the application is the much feared personal statement. This is your chance to convey boundless enthusiasm for the subject. So economy of expression is foremost. Omit dull and ineffective generalities and make sure you give concrete examples.Admissions officers read every personal statement that arrives. It is not convincing if you say you have chosen the subject because you enjoy it. You have to get across what it is about a particular area that has inspired you. They will look for evidence that you have reflected and thought about the subject.Applicants should be honest. There is no point saying you run marathons if you are going to be out of breath arriving at the interview on the second floor.19. What is the first decision you should make in preparing to apply for a place at a university?20. What is the most important part of the application?21. What must applicants do in their personal statements?Questions 22 to 25 are based on the passage you have just heard.It is usually agreed that a German, Carl Benz, built the first motor car in 1885. It was actually a tricycle with a petrol motor at the rear. Soon, members of the royal family and other wealthy people took up motoring as a sport. Many of the early cars had 2 seats. There were no petrol pumps and few garages, so every driver had to be his own engineer for the frequent breakdowns.By 1905, cars began to look like cars of today, with head lamps, wind screen, rubble tyres and number plates. Henry Ford's Model T introduced in America in 1909 was cheaper because it was made on the assembly line. It brought cars closer towards the reach of ordinary people. With the popularity of the car, registration became a must in 1903 with the Motor Car Act. Competency tests were introduced in 1935.Today, the legal driving age for a car in the UK is 17. You are not allowed to drive a car unsupervised until you have passed a driving test. In 1958, Britain celebrated the opening of its first motorway – the Preston Bypass. Until then, no one really understood what a motorway was, not even the laborers who were building it. The bypass held a new era in motor travel and was greeted with excitement and optimism. Service stations came with the motorway and the legend of the transport cafe was born. Of course, the service station has diversified greatly. But whether it’s an English-cooked breakfast or a coffee and a sandwich, one thing has remained the same: the prices.22. What does the speaker say about the first motor car?23. What was the problem with the early cars in Britain?24. Why did Henry Ford's Model T cars cost less?25. What do we learn about the Preston Bypass?。

2020春国家开放大学《应用写作》形考任务1-6参考答案形考任务11．结合教材，从主旨、材料、结构、语言等四个方面阐述实用型文章的特征。

（15分）2．结合自身学习经历与体验，谈谈范文阅读对提高实用型文章写作水平的重要性。

（25分）3．结合教材，简述公文的概念、特点、功用、构成要素与分类。

（20分）4．在以下五个文种中任选两个文种，进行写作练习。

（40分）（1）通知（2）报告（3）请示（4）函（5）会议纪要要求：内容要明确，中心要突出；格式要正确，写法要规范；语言要准确、简明、得体，书写要清楚。

答题要点：问题1：答：实用型文章的特征就分别体现在以下这四个方面：章中的体现。

单一，是说一篇文章中只能有一个中心，只能围绕着一个主题把问题说清楚，而不能把关系不大甚至不相关的问题写到一篇文章中去，使写出的文章多中心、多主题，集中，是说一篇应用文只能有一个中心，而这个中心应是全文的统帅，应对文章内容有制约作用，全文要不枝不蔓，紧扣这个中心。

明确，是说文章的中心意思，作者的意图和主张是什么，要使读者一看便知，而不必费心揣摩，文艺作品所讲究的曲折与含蓄，恰恰为实用型文章所排斥。

（二）材料多样，真实有力，材料是构成文章内容，形成支撑并表达主旨的各种事实与理论，真实是实用型文章的生命，而材料的真实又是使文章具有真实性首要条件，有力是实用型文章的材料所应具备的另一个特点。

（三）结构合理、谨严固定，简单地说，结构是文章的内部构造，安排结构，就是根据主旨表达的需要，合理地组织材料，实用型文章应该是一种逻辑构成，而逻辑构成则要讲求谨严性，而不能流于松散无序，文章首尾圆合，衔接紧密，层次清晰，段落分明，则是文章结构谨严最起码的条件，也是对应用文结构最基本的要求。

固定是实用型文章结构的一个重要特点，遵照固定的模式写作，材能把文章写的规范，也才能使写出的文章便于阅读，易于发挥实际效用。

（四）语言准确，简明、平易、庄重。

culture.You may need to include the 5Ws and 1H elements.参考答案：With the rapidly growing popularity of science and technology,the process of globalization made great achievements.We have more chances to communicate with foreigners.Intercultural communicator has increasingly become a popular central issue of the public.To discuss this issue from cognitive perspective.western culture is based on individualism rather than on collectivism.Forinstance,in the US,you always talk about individual rights.This is clearly different in China where a country is placed above your own self.From the affect point of view,Chinese emotional expression is subtle but not directly.On the contrary,westerners express more enthusiastic.Furthermore,the Chinese people do not say yes or no,they are more accustomed to tactfully convey his meaning.No doubt,the Westerners would like to directly deliver how they think and what they want.In behavior,many behavioral differences are due to the impact of many aspects which cover environmental,cultural,historical and other factors.Do not ask for the age and income is a case in point.We should respect others.Respect for their privacy,their national culture,and religious beliefs.Second,we want to maintain friendly,and convey information clearly passed on through language or body language.Moreover,we just express ourselves in all sincerity and with warmth.Finally,the misunderstanding of cultural differences,we should learn to accommodate.。

习题六6-1 (1) A; (2) C; (3) B; (4) C; (5) A6-2，黑表笔插入COM，红表笔插入V/Ω（红笔的极性为“+”），将表笔连接在二极管，其读数为二极管正向压降的近似值。

用模拟万用表测量二极管时，万用表内的电池正极与黑色表笔相连；负极与红表笔相连。

测试二极管时，将万用表拨至R×1k档，将两表笔连接在二极管两端，然后再调换方向，若一个是高阻，一个是低阻，则证明二极管是好的。

当确定了二极管是好的以后就非常容易确定极性，在低阻时，与黑表笔连接的就是二极管正极。

6-3 什么是PN结的击穿现象，击穿有哪两种。

击穿是否意味着PN结坏了？为什么？答：当PN结加反向电压（P极接电源负极，N极接电源正极）超过一定的时候，反向电流突然急剧增加，这种现象叫做PN结的反向击穿。

击穿分为齐纳击穿和雪崩击穿两种，齐纳击穿是由于PN结中的掺杂浓度过高引起的，而雪崩击穿则是由于强电场引起的。

PN 结的击穿并不意味着PN结坏了，只要能够控制流过PN结的电流在PN结的允许范围内，不会使PN结过热而烧坏，则PN结的性能是可以恢复正常的，稳压二极管正式利用了二极管的反向特性，才能保证输出电压的稳定。

对于图(a)假定D1、D2、D3截止，输出端的电位为-18V，而D1、D2、D3的阳极电位分别是-6V、0V、-6V，因此，理论上D1、D2、D3都能导通，假定D1导通，则输出点的电位为-6V，由于该点电位也是D2的阴极电位，因此D2会导通，一旦D2导通，u O点的电位就为0V，因此，D1、D3的阴极电位为0V，而阳极端为-6V，这样D1、D3必定截止，所以输出电压u o=0V（这就是脉冲数字电路中的或门，0V为高电平，-6V为低电平，只要输入端有一个高电平，输出就为高电平）。

对于图(b)依同样的道理可知：D1、D2、D3的阳极电位都低于+18V，所以三个二极管均截止，流过R的电流为0，故输出电位u o=18V试分析图(b)中的三个二极管极性都反过来，输出电压u o=？6-5 现有两只稳压二极管，它们的稳定电压分别为5V和9V，正向导通电压为0.7V。
