UNIT 1 创造性思维的艺术约翰·阿代尔创造性对人类发展至美重要。
下面的文章里，约翰·阿代尔为求实的创造性思维者提供了一些颇有见地的见解和技巧。
创造性思维在今天的重要性不需要强调。
在你的职业中或工作领域,如果你能够发展提出新思想的能力,你就有竞争优势。
在你的个人生活中，创造性思维也能将你带上创新活动之路。
它可以丰富你的人生,尽管并非总是以你期待的方式。
人类创造力人类不可能凭空创造东西。
有一次，一位来宾极为仔细地参观了亨利·福特的汽车公司，然后见到了福特。
来宾心中充满了惊奇和崇敬，他对这位实业家说:“福特先生，25年前起家时几乎一无所有的人，不可能实现这一切。
”福特回答说，“这个说法可不太对。
每个人都是靠所有拥有的东西来起家。
这里什么都有——所需要的一切,它们的基本点和实质性的东西都已存在。
”潜在的材料，也就是可以做成或建构成某种东西的元素之成分或者实质的材料，都已存在于我们的宇宙。
你可能已经注意到,我们倾向于将创造性这个词用在与使用的原材料很不一样的产品上。
鲁宾斯的一幅名作，就是蓝色、红色、黄色和绿色的蠕虫般颜料在艺术家画板上的集合。
物质材料，对艺术家来说是颜料和画布;对作家来说是纸和笔——完全是次要的。
这里的创造，更多的是在大脑之中。
感知、思想和感觉都在一种观念或想象中结合起来。
当然，艺术家、作家或作曲家还需要使用技巧和技术，在画布或纸上把头脑中构想出来的东西塑造成型。
和普通意义上的创造性一样，创造性思维遵循同样的原则。
我们的创造性想象必须有可以加工的对象。
我们不能凭空产生新的思想。
如上面福特所说的那样，原材料都在那里。
有创造力的大脑在原材料中看到可能性和相关性,而创造力不强的大脑却看不到。
这一结论让我们大大地松了一口气。
你不用凭空构想新的想法。
作为创造性思维者,你的任务是将已经存在的想法或元素组合在一起。
如果最终把人们从未想过可以联系起来的想法或事物，用看似不可能却很有价值的方式组合起来，那人们就会认为你是创造性思维者。

新编大学英语第二版第三册第三单元课文翻译编著：浙江大学出版社：外语教学与研究出版社挂钥匙的孩子——笃、笃，家里有人吗？在过去的几十年中，美国的生活费用一直在持续增长。
食品价格。
服装费用、房子开销和学费都越来越高。
母亲们纷纷放弃传统的全职家庭主妇的角色，这一部分是由于经济需要，一部分是想通过工作取得成就感。
她们越来越多地从事家庭以外的有薪水的工作。
如此重大的角色转换影响着整个家庭，尤其是孩子们。
某些后果是非常明显的。
例如，晚饭时间推迟了。
而另一方面，这种转变对情感的影响就更微妙了。
母亲们早上带着愧疚感离开家，因为孩子放学回来时她们会不在家。
她们压抑着愧疚心理，因为她们相信她们的工作从长远来讲对大家有益。
她们的收入将能够使家庭存下钱来供孩子上大学。
度一次长假、买辆新车，等等。
孩子们在情感上所受到的影响是很大的。
通常，孩子会感到受伤和愤怒。
毕竟，他们一个人呆几个小时，他们感到他们的母亲应该“在那儿”等着他们。
他们可能需要有人帮他们完成作业，或者想把一天的活动说给母亲听。
然而，母亲们通常筋疲力尽地回到家，又要面临一个紧迫的任务——准备晚饭。
她们的首要任务是给全家人做晚饭，而不是轻松的聊天。
挂钥匙的孩子年龄从六岁到十三岁不等。
每天，他们放学回家，用挂在脖子上的钥匙打开门，独自一人，孤孤单单地呆在安静而空荡荡的屋子里。
对某些孩子来说，这段个人时间是很有所作为的，而对于另外一些孩子，却是令人害怕的孤单的空虚。
由于安全原因，很多父母不允许孩子出去玩，或带客人到家里来。
因此，孩子们感到一种被隔离的感觉。
被采访的挂钥匙的孩子们反应不同。
一些孩子说，每天自己呆上几个小时培养或激发了他们的独立意识和责任心。
他们感到被爱、被信任，并且这一感觉鼓励他们自信。
挂钥匙的女孩子通过观察母亲如何持家和工作，学习了职业母亲的行为榜样。
一些孩子称他们利用这段不受监督的自由时间来提高他们的运动技能，如打篮球。
还有一些孩子读书或练习乐器。

山东省菏泽市第一中学2024-2025学年高一上学期10月月考英语试题一、阅读理解When you are about to go to a boarding school (寄宿制学校) in England, there are many different questions that may come to mind. But once you look at them with some perspective (视角), you will certainly feel easy. Here is a normal boarding day.Early Morning:Usually boarders get up around 7:00 am and have around an hour to take a shower and put on their uniform before breakfast.Lessons:Classes start at 9: 00 am and every lesson lasts for 50 minutes. After two lessons, at 10: 40 am, you’ll have a short break. The next period of classics will include two more lessons.Lunch:Lunch is usually held around 12:30 pm at the dining hall, where you’ll join your friends to enjoy a hot dish. After an hour of lunch, you’ll have three or four more lessons to attend.Dinner:At 5:00 pm you will have finished your school lessons for the day. Most boarding schools in the UK offer their full boarders different kinds of hot meals to choose from.Activities/ Sports:All boarding schools in the UK provide many different kinds of activities for their boarders, such as football, swimming, golf or art.Prep:An important part of boarding school life is the supervised homework session known as “prop”. Although “prep” might sound stressful, it’s a great way for you to keep up with your studies.Free time:Once you have done all your classes and activities, it’s time to relax.Bedtime:In most boarding schools, the lights go out around 10:30 pm.Being nervous just before you go to a boarding school is completely normal and understandable. Hopefully, knowing the usual routine (常规) can help you. Once you are there, you will also see how exciting life in a boarding school in England can be.1．What can help you keep up with your studies in the boarding school?A．Doing activitıes.B．Having lessons.C．Enjoying free time.D．Supervised homework sessions.2．What do we know about boarding schools in England from the text?A．Classes usually start at 8:30 am.B．Students can have a short break after four lessons.C．They don’t give students any free time.D．They turn off the lights around 10:30 pm. 3．What is the purpose of the text?A．To help students know about boarders’ life.B．To attract more students to boarding schools.C．To introduce a new school life.D．To advertise for boarding schools.I want to share with you a story from 28 years ago. My dad was a used car salesman. Every Thursday night, he would head off to Shreveport, LA for an auction (拍卖会). Most of the time, I drove a car over there for him so he could sell it at the auction.One day I was riding with my dad when he noticed a hitch-hiker (搭便车的人) with a backpack. Without hesitation, he pulled the car over and offered him a ride. Dad asked him his name, and proceeded to talk to him about all sorts of things. Dad asked him where he was going. The hitch-hiker told him that he was heading for the west. I can’t recall why but he told Dad a lot of things that had occurred to him and that persuaded him to make that decision. He talked about the tragic events that occurred to him several years before. He was in low spirits, but I could see that the hitch-hiker’s attitude was changing as someone was really listening to him.We drove 45 minutes before the hitch-hiker got off. We pulled over and Dad told him to keep his head up and things would start looking up for him soon. He reached into his pocket and handed the hitch- hiker a twenty-dollar bill. The guy smiled. He nearly lit up right there on the cold, dark highway.We drove on and my dad did not say a single thing. I was still completely surprised by what I had just witnessed. I was always told by everyone never to pick up a hitch-hiker and yet my dad did it every single time he saw one. While reflecting upon that story I came to understand that just one single kind act could change someone’s life. And I am sure that my father’s deed made that poor man’s day.4．What made the hitch-hiker become less upset?A．The writer’s father talking to him about all sorts of things.B．The writer’s father offering him a free ride.C．The writer’s father really listening to him.D．The writer’s father agreeing to drive him to his destination.5．When his father helped the hitch-hiker, the writer ___________.A．was deeply moved B．strongly disagreedC．admired his father D．couldn’t understand6．Which of the following words can be used to describe the father?A．Wealthy.B．Warm-hearted.C．Far-sighted.D．Adventurous.7．What’s the writer’s main purpose of writing this text?A．To tell a story of his father.B．To show his respect for his father.C．To prove his father is the best teacher.D．To advise people to learn from the hitch-hiker.What you do after studying could have a big effect on how well you learn and remember. Today on Education Tips, we will explore two no-cost ways that can help you improve your learning: wakeful rest and sleep.When many students finish studying, they often go straight to another activity. Perhaps they look at their phone or computer. They might even play a video game or watch television. But research suggests that resting after your study may help you remember what you have studied.The basic idea is this: by stopping your activity after the study, your brain gets a chance to rest. Resting is difficult when you are playing computer games.While this might sound unusual to you, many studies have explored the benefits of resting after learning—what is called “wakeful rest”.A 2019 study found that both young and older adults were able to better remember information they learned after doing wakeful rest.If you want to give “wakeful rest” a try, here are a few simple things to do. Rest quietly for five to ten minutes. Do not look at your phone, read stories or play games. It is really that easy!Besides wakeful rest, sleep is also important for learning. The Division of Sleep Medicine at Harvard Medical School (HMS) notes that sleep helps people to learn in two ways. A report on the school’s website explains that “a sleep-deprived person cannot focus attention well and therefore cannot learn well”. It also says, “Sleep itself helps us to memorize and that memorizing is very important for learning new information.”The National Sleep Foundation (NSF) suggests that adults between the ages of 20 and 64 get between 7 and 9 hours of sleep per day. Teenagers may need a little bit more, and people over the age of 65 may need a little less.Try to get some “wakeful rest” after a study. Then try to get a good night’s sleep. That’s it—a simple, no-cost way to help you remember what you learn.8．What is paragraph 3 mainly about?A．The importance of sleep.B．The good ways to get a rest.C．The reason for having a rest.D．The types of resting activities.9．Which activity might be recommended shortly after studying?A．Reading a newspaper.B．Playing a video game.C．Sitting there doing nothing.D．Having a nice sleep at night.10．How long should teenagers sleep each day according to NSF?A．Less than 7 hours.B．Just 7 hours.C．No more than 9 hours.D．Around 9 hours.11．What can be a suitable title for the text?A．Low-cost Tips on Working B．Good Things to Do After Your StudyC．Why Do We Need to Have a Good Sleep?D．How Long Should We Rest AfterLearning?Exams are brain-burning. The silence of the hall; the beating of the clock; the watchful eye of the teacher; the proud expression of the person who has finished 15 minutes early. So it is not surprising that those who feel anxious in the exam do worse than those who do not. But different from the existing(现存的) point of view, the recent study by Maria Theobald shows that the pressure of revision affects(影响) your exam performance.To test this idea, Dr Theobald worked with 309 German students who were preparing for their final exam. During the 100 days before the real exam, these students used an online learning app which showed them old exam questions and recorded their performance. And 40 days before the real exam, they also took a mock(模拟) exam. Their levels of anxiety were also be recorded and assessed(评定), every day for 40 days before the real exam and also on the day of that exam.The result was not what she expected. Anxiety on the day of the test did not predict(预测) exam performance at all. It was the level of knowledge in the mock exam and the earlier practices that predicted it. Those who performed well in the mock exams also did well in the real test, no matter how anxious they were on the day.It turned out that what really affected students were high levels of anxiety during the weeks before the exam. The greater a student’s anxiety in the days before the exam, the lower his or her knowledge gain was. To reduce this anxiety, she gives some advice for students when they revise. First, they can raise their confidence in their own abilities by reminding(提醒) themselves of how much they know. Second, they can diminish the importance of the test by reminding themselves that, though it is important, it is not a life or death situation. It really isn’t.12．What influences exam results according to the existing view?A．Exam levels.B．Exam schedule.C．Pressure from the exam hall.D．High expectations(期望) from teachers. 13．How did Dr Theobald go on the study?A．By asking students some questions.B．By collecting the data(数据).C．By asking experts` advice.D．By following students’ performances. 14．What does the underlined word “diminish” probably mean in the last paragraph?A．Reduce.B．Influence.C．Realize.D．Understand. 15．Which of the following is the suitable title for the text?A．Never Too Late to Revise B．Never Put Off Revision till TomorrowC．Anxiety in Revision, Failure in Exam D．The More Pressure, The Better ResultsPeer PressurePeer pressure is a part of life. 16 This peer group may be of similar age but can also be defined by other commonalities (共同点), including motherhood, professional affiliations, and your local neighborhood.Peer pressure is not always negative. Trying to fit into a healthy social group, for example, of peers getting good grades, joining sports teams, and making plans for their futures, is positive.17 Peer influence can show you there is support, encouragement, and community available to you. By seeing someone else do something positive, you may reflect on your own life choices, goals, and where you spend your time.18 Being pressured by peer, whether it happens in person or online, may shake your sense of identity and self-confidence. For example, you may feel pressure to do unsafe things that have risks you may not fully know.19 You can also work on surrounding yourself with more positive influences. Some ways of coping with peer pressure include:● Not spending time with people who pressure you to do things that feel wrong or dangerous.● Learning to say “no” and practicing leaving situations that feel unsafe or uncomfortable.● Talking to a trusted peer or professional (teacher, counselor) if you have problems saying “no” or are feeling pressured to change something about yourself.● 20In the journey of life, peers influence our steps. If you embrace positive guidance and stand firm against negativity, you can become the architects of your own story.A．Some refer to this type of peer “pressure” as peer “influence”.B．It can be direct or indirect, positive or negative.C．It is any type of influence that comes from a peer group.D．Getting over peer pressure means not accepting the negative influence of others.E．While peer influence can improve your life, peer pressure can cause problems.F．Feeling pressured to do things that may make you feel bad about yourself is unhealthy.G．Befriending people who have a positive influence.二、完形填空Jenna had graduated from middle school and was ready for new 21 in high school.22 , high school was different.

大学英语精读第3册_课文及课后答案
UNIT 1课文翻译一位青年男子发现,漫无目的的逛街也会惹官司。
误会一场接一场，直到最终他必须出庭受审……法律小冲突我平生就一次陷入法律困境。
当时被捕并被传上法院的全过程是件相当不愉快的经历，但现在可用此编个好故事。
让人非常烦恼的是我被抓和接着在法庭的命运中那些主观武断的情景。
此事大约发生在十二年前的二月份。
那里我已中学毕业了几个月，并要等到该年十月份才能上大学。
那段时间，我仍住在家中。
一天早晨，我去了里士满，那是离我的地址不远的伦敦郊区。
我正在找一份临时工作以便攒点钱去旅行。
由于天气晴朗，且无急事，我便悠闲自得地看看商店橱窗，逛逛公园，甚至有时只是呆站着到处观望。
很可能是这种明显的无所事事的样子导致了我的不幸。
事情发生的时间是大约十一点半。
我正从地方图书馆走出来，本想在那里找一份工作而一无所获。
此时看到一位男士从街对面走来，显然打算和我讲话。
我猜想他是向我问时间。
然而，他说他是警官并要逮捕我。
起初，我想这是在开玩笑，但接着又来了一位警察，并穿着警服。
我便深信不疑了。
“但为什么呢？”我问。
“到处遛达，有作案嫌疑。
”他说。
“作什么案？”我问。
“偷窃，”他说。
“偷什么？”我问。
“牛奶瓶，”他说，还做出非常严肃的样子！“噢，”我说。
事情的缘由是那一带有许多小窃贼，特别是有从门前台阶上盗奶瓶的小偷。
接着，我犯了一个大错误。
那时我正十九岁，头发长而蓬乱，并把自己当作六十年代“逆文化年轻人”的一员。
因此，我装着一副冷漠的毫不在乎的样子。
所以我说“你们跟踪我多久啦？”说话的腔调尽量装出无所谓有样子，就象随便谈话一样。
于是在他们看来我是十分熟悉此类事情，这使他们更加坚信我彻头彻尾是个名声不好的人。
几分钟后，一辆警车来了。
“坐到后排去，”他们说：“把手放在前排椅背上，不要挪动。
”他俩坐在我的两边。
这倒不是开玩笑的。
在警察局他们审问了我几个小时。
我继续尽力做出深谙世故并对此事习以为常的样子。
当他们问我一直在干什么时，我告诉他们我一直在找工作。

（让我们）更仔细地看一下二者的关系。
你是个悲观主义者，还是个乐观主义者？你看待（生活）的方式确实影响着你的生活态度，你清楚吗？请记住：改变了你的人生观，就改变了你的生活态度。
1 父亲低头年看着小床里睡得正熟的女儿，女儿出生没几天，刚从医院回家。
她的漂亮和完美使他心中充满了敬畏和感激。
2 这时孩子睁开了眼睛，直直地向上方望着。
3 父亲叫她的名字，期待着她转头看他。
她的眼睛却一动不动。
4 他拿起系在婴儿床围栏上的小绒毛玩具摇起来，玩具上的响铃发出叮叮当当的声音。
孩子的眼睛还是一动不动。
5 他的心跳开始加速。
他在卧室里找到了妻子并把刚刚发生的事告诉了她。
“她似乎对声音毫无反应，”他说。
“好像她根本听不到。
”6 “我敢肯定她一切正常，”妻子说着，一边披上晨衣。
他们一起走进了婴儿的房间。
7 她叫着孩子的名字，把铃摇得叮当响，还拍手。
随后她把孩子抱起来，这时孩子一下子变得活泼起来并发出开心的声音。
8 “天哪，”父亲说，“她是个聋子。
”9 “不，不会的，”母亲说。
“我是说，现在这么说太早了。
你看，她刚出生不久，视线还不能集中呢。
”10 “可是刚才你那么用力地拍手，她都没有一点反应。
”11 母亲从书架上拿了一本书。
“让我们看看这本育儿书上怎么说，”她说道。
她查到“听觉”栏，大声读道：“‘如果你的新生儿听到响声不吃惊，或者不会朝向发出声音的方向，不必慌张。
因为对声音的反应通常要过一段时间才会出现。
你的儿科医生可以从神经系统方面对孩子的听觉进行测试。
’”12 “瞧，”母亲说道，“这是不是让你感觉好多了？”13 “没好多少，”父亲说。
“书里甚至都没提还有另一种可能性，那就是孩子是聋子。
我只知道我的宝贝什么也听不见。
我有一种最可怕的预感。
也许这是因为我的祖父就是聋子的原因。
如果我们漂亮的小宝贝真是聋子而且是我这一方的原因，我将永远无法原谅自己。
”14 “嗨，等等，”妻子说。

新时代交互英语3-4英语课文翻译
新时代交互英语3-4英语课文翻译第三册第1单元为乐趣而读书与为学习而读书或许你觉得你已经很会读书了，毕竟，你把生命中的大部分时间都花在读书上。
或许你并不喜欢读书，因为你更喜欢电视而不是印刷品。
或许你认为让别人直接告诉你一些信息会更好。
或许你觉得英语对你来说很难读懂。
3 不管你具有什么样的能力，提高阅读能力需要有技巧，这些技巧可以帮助你更好地应对高等教育所涉及的内容。
本章将介绍几种阅读技巧。
如果你在里面没有找到你所需要的技巧（比如，你觉得自己在阅读英语（第二语言）时需要帮助），你可以通过学校的学习中心或实验室寻求帮助。
两种类型的阅读4 阅读主要分两种：一种是为乐趣而读，一种是为学习而读。
5 为乐趣而读：你可以读一些诸如历险、罗曼史、体育运动等方面的文章，只读一遍，就可以从中得到娱乐。
许多小说、杂志和报纸中都有这种文章。
你没必要细细地阅读，除非你愿意。
6 为学习而读：大多数阅读是为了学到某些方面的知识而进行的。
因为你必须理解所读内容，或许还要牢记。
比如，当你在阅读有关烹饪或教授如何修理汽车的文章时，你当然得认真些了。
7 为学习而读，这是一生中都必须坚持的事。
不管学习是为了取得驾照，还是为了了解小孩的服药量。
事实上，许多经理和管理者每天所做的事，比如读报告、看书信及备忘录等，都是为了学习而阅读的。
8 但是，他们的这种为学习而读，与读教科书是有区别的：在高等教育中，你通常需要不止一遍地阅读同一篇文章，其原因当然是因为在高等教育中，你必须理解和记忆大量阅读内容。
阅读以提高长期记忆9 “哦，伙计，”你或许会想，“你是说我不可能做到把一篇文章只读一遍就立刻理解吗？”10 如果你是那种只需扫一眼就能记住自行车牌号或存物柜密码的人，或许你能够做到。
然而，大多数人需要多看几遍才能记得住。
11 这就是短期记忆与长期记忆的问题。
记忆的信息会在接触信息后的24小时内逐渐被遗忘（这就是“遗忘曲线”）。
12 有些学生或许会以此作为考前突击的理由——把一切都拖到考试前的最后一天来硬记。
新编大学英语3 第三单元课文翻译
After-class Reading Passage参考译文挂着钥匙的小孩––––笃，笃，有人在家吗？1 在美国过去的几十年中，生活开支一直在持续上升。
食品价格、服装开支、住房开支以及学费不断增高。
母亲们已经不再扮演专职家庭主妇的传统角色，这在一定程度上是出于经济上的需要，一定程度上也是为了使自己有一种成就感。
她们越来越多地在从事着家庭以外的带薪水的工作。
2 这样重大的角色转换影响到整个家庭，尤其是小孩。
某些后果是显而易见的。
例如，晚饭时间推迟了。
然而，这种转变对感情上的影响更为微妙。
母亲们早上带着负疚感离开家，因为孩子放学回家时她们不能在家等候。
她们压抑着负疚心理，因为相信从长远来看这份工作对大家都有利。
她们的收入能够使家庭积攒起孩子的大学学费、全家度一个更长的假期、买一辆新车，等等。
3 孩子们在感情上所受到的影响是很大的。
孩子们普遍感到受了伤害，有怨恨情绪。
毕竟有好几个小时他们要独自呆在家里，而他们觉得母亲应该“在那儿”等着他们。
他们也许会需要母亲帮他们完成家庭作业，或是想把一天里的活动说给母亲听。
然而十分常见的情况是：母亲们回到家里已经疲惫不堪，又面临着一个紧迫的任务––––做饭。
她们的首要任务是为全家人做晚饭，而不是放松地聊天。
4 挂钥匙的孩子们的年龄从6岁到13岁不等。
每天他们放学回家，用挂在自己脖子上的钥匙打开家门。
然后就独自呆在安安静静、空空荡荡的房间里。
对于某些孩子来说，这是一段属于他们自己的有所作为的时间，而对于另一些孩子来说则是令人恐惧的、孤独的空虚。
为了安全的原因，许多父母不允许他们的孩子出去玩或是让别的孩子来家玩。
因此这些孩子有一种被隔离的感觉。
5 接受采访的挂钥匙的孩子们的反应不同。
一些孩子说每天有几个小时让他们独自呆在家里培养了或者说激发了他们的独立意识和责任感。
他们觉得受到了关爱与信任，而且这种感觉增强了他们的自信心。
（挂钥匙的）女孩子们通过观察母亲们如何对付家庭与工作中的难处而学习了职业母亲的行为榜样。

新视野大学英语读写教程【第三版】第三册课文原文与翻译
Unit 1Text A Never, ever give up!永不言弃！1 As a young boy, Britain's great Prime Minister, Sir Winston Churchill, attended a public school called Harrow. He was not a good student, and had he not been from a famous family, he probably would have been removed from the school for deviating from the rules. Thankfully, he did finish at Harrow and his errors there did not preclude him from going on to the university. He eventually had a premier army career whereby he was later elected prime minister. He achieved fame for his wit, wisdom, civic duty, and abundant courage in his refusal to surrender during the miserable dark days of World War II. His amazing determination helped motivate his entire nation and was an inspiration worldwide.英国的伟大首相温斯顿·丘吉尔爵士，小时候在哈罗公学上学。
当时他可不是个好学生，要不是出身名门，他可能早就因为违反纪律被开除了。
谢天谢地，他总算从哈罗毕业了，在那里犯下的错误并没影响到他上大学。

2请参见图示。
图中所示配置不支持交换机形成中继。
此问题最可能的原因是什么？Cisco 交换机只支持ISL 中继协议。
当链路两端均设置为自动模式时，无法通过协商建立中继链路。
默认情况下，Switch1 只允许VLAN 5 使用该链路。
应在两台交换机上配置相同的本征VLAN。
3请参见图示。
计算机 1 向计算机 4 发送了一个帧。
在计算机1 与计算机4 之间路径的哪些链路上会将VLAN ID 标记添AA、BA、B、D、GA、D、FC、EC、E 和F4请参见图示。
公司人力资源部门准备在新的公司办事处增加专用应用程序工作站PC4。
公司还将新增一台交换机S3，通过到另一台交换机S2。
出于安全原因，新PC 位于HR VLAN，即VLAN 10 中。
新办事处使用子网172.17.11.0/24。
但安现有PC 无法访问PC4 中的共享资源。
原因可能是什么？必须将交换机之间的连接配置为接入端口才能允许访问S3 上的VLAN 10。
新PC 位于不同子网中，因此必须将S3 的Fa0/2 端口配置为中继端口。
PC4 必须与其它HR VLAN PC 使用同一子网。
一个VLAN 不能跨多台交换机。
5网络管理员正在从交换机删除多个VLAN。
当管理员输入no vlan 1命令时，收到错误消息。
此命令为什么产生错误消息？在任何情况下都不能删除VLAN 1。
只能通过删除vlan.dat 文件来删除VLAN 1。
只有删除VLAN 1 的所有端口后才能删除VLAN 1。
只有将VLAN 1 的角色分配给其它VLAN 后，才能删除VLAN 1。
6在多台交换机之间规划VLAN 流量时，有效的考虑因素是什么？将交换机间的连接配置为中继链路会导致任一VLAN 中的所有主机均会收到其它VLAN 发出的广播。
中继连接会受到该中继链路上任何一个VLAN 中广播风暴的影响。
将交换机之间的中继连接限制在一个VLAN 内可提高端口利用率。
在一个接入端口上传输所有VLAN 流量可实现流量的正确分离。
7当删除VLAN 时，该VLAN 的成员端口会发生什么变化？这些端口将无法与其它端口通信。
这些端口会默认返回到管理VLAN 中。
这些端口会自动成为VLAN1 的成员。
这些端口仍然保持该VLAN 的成员身份。
直到交换机重新启动后，它们将成为管理VLAN 的成员。
8默认交换机配置中的VLAN1 有哪两项特点？（选择两项。
）VLAN1 应重命名。
VLAN 1 是管理VLAN。
所有交换机端口都是VLAN1 的成员。
仅交换机端口0/1 被分配给VLAN1。
交换机之间的链路必须是VLAN1 的成员。
9命令switchport mode dynamic desirable有什么效果？由于本征VLAN 不是默认VLAN，DTP 将无法协商中继链路。
除非相连的远程接口也配置为动态期望模式，否则该接口无法协商中继链路。
相连的设备会动态确定必须通过该链路传输多个VLAN 的数据的时机并根据需要打开中继链路。
如果使用switchport mode dynamic auto命令或switchport mode trunk命令配置远程相连设备，则会形成中继10请参见图示。
从生成图中所示的输出的交换机可得出哪两条结论？ （选择两项。
）网络管理员配置了 VLAN 1002-1005。
VLAN 处于活动状态，且正在协商配置参数。
此交换机上配置了 FDDI 中继链路。

不允许VLAN 50 进入交换机Switch1 和Switch2 之间的中继链路。
13如果邻居交换机端口处于“动态期望”模式，那么哪些交换机端口模式可以让交换机成功形成中继链路？动态期望模式打开或动态期望模式打开、自动或动态期望模式打开、自动、动态期望或非协商模式14网络管理员希望将大楼 A 中的主机划分到编号分别为20 和30 的VLAN 中，下列关于VLAN 配置的说法中哪两项正确项。
）可以为这些VLAN 命名。
VLAN 信息保存在启动配置中。
手动创建的非默认VLAN 必须使用扩展范围的VLAN 编号。
网络管理员可在全局配置模式或VLAN 数据库模式下创建VLAN。
两个VLAN 都可命名为BUILDING_A 以与处于不同地理位置的其它VLAN 区分。
15请参见图示。
计算机 B 无法与计算机 D 通信。
此问题最可能的原因是什么？交换机之间的链路处于工作状态，但未配置为中继链路。
VLAN 3 不被允许进入交换机之间的中继链路。
路由器未正确配置，无法在VLAN 间路由流量。
计算机 D 不具有属于VLAN 3 地址空间的正确地址。
