Sample讲解

日程表的讲解用英文范文Alright, here's a sample of an explanation of a schedule in English, following the given guidelines:You know, organizing your day with a schedule can be really helpful. It's like having a map for your day. You see, with a schedule, you can plan ahead for your meetings, appointments, and even your breaks. You'll never miss a thing!Just imagine, when you wake up in the morning, you check your schedule and see that you have a meeting at 10. Well, that gives you a heads up, right? You can have a leisurely breakfast, maybe read the news, and then get ready for the meeting. No rush, no stress.And speaking of breaks, let's not forget about them! A good schedule always has room for some downtime. Maybe you like to go for a walk during lunch or catch up with afriend over coffee. Your schedule should reflect that too,giving you time to relax and recharge.Another great thing about schedules is that they help you prioritize. You can see which tasks are urgent and which ones can wait. This way, you can focus on the important things first and get them done efficiently.Of course, schedules aren't set in stone. Sometimes, things happen that you can't predict. But that's okay!。

RANSAC算法讲解RANSAC是“Random Sample Consensus（随机抽样一致）”的缩写。

它可以从一组包含“局外点”的观测数据集中，通过迭代方式估计数学模型的参数。

它是一种不确定的算法——它有一定的概率得出一个合理的结果；为了提高概率必须提高迭代次数。

RANSAC的基本假设是：（1）数据由“局内点”组成，例如：数据的分布可以用一些模型参数来解释；（2）“局外点”是不能适应该模型的数据；（3）除此之外的数据属于噪声。

局外点产生的原因有：噪声的极值；错误的测量方法；对数据的错误假设。

RANSAC也做了以下假设：给定一组（通常很小的）局内点，存在一个可以估计模型参数的过程；而该模型能够解释或者适用于局内点。

一、示例一个简单的例子是从一组观测数据中找出合适的2维直线。

假设观测数据中包含局内点和局外点，其中局内点近似的被直线所通过，而局外点远离于直线。

简单的最小二乘法不能找到适应于局内点的直线，原因是最小二乘法尽量去适应包括局外点在内的所有点。

相反，RANSAC能得出一个仅仅用局内点计算出模型，并且概率还足够高。

但是，RANSAC并不能保证结果一定正确，为了保证算法有足够高的合理概率，我们必须小心的选择算法的参数。

二、概述RANSAC算法的输入是一组观测数据，一个可以解释或者适应于观测数据的参数化模型，一些可信的参数。

RANSAC通过反复选择数据中的一组随机子集来达成目标。

被选取的子集被假设为局内点，并用下述方法进行验证：1.有一个模型适应于假设的局内点，即所有的未知参数都能从假设的局内点计算得出。

2.用1中得到的模型去测试所有的其它数据，如果某个点适用于估计的模型，认为它也是局内点。

3.如果有足够多的点被归类为假设的局内点，那么估计的模型就足够合理。

4.然后，用所有假设的局内点去重新估计模型，因为它仅仅被初始的假设局内点估计过。

5.最后，通过估计局内点与模型的错误率来评估模型。

这个过程被重复执行固定的次数，每次产生的模型要么因为局内点太少而被舍弃，要么因为比现有的模型更好而被选用。

Sample test one. Part A. Spot dictation. Directions. In this part of the test you will hear a passage and read the same passage with blanks in it. Fill in each of the blanks with the words you have heard on the tape. Write your answer in the corresponding space in your answer booklet. Remember you will hear the passage only once.The parents set the rules and the children obey. Right? Wrong? In a growing number of North American families adults have let their children take over. Parents want to be nurturing a love and make their small children happy. But many have become confused about the best way to achieve this, explains a noted child psychologist. Large number of parents are being controlled by their children to the point that the entire families end up organizing themselves around a small child’s emotions. The problem is that many mothers and fathers try to be a friend to their children. However parenting is not a popularity contest. Challenging authority is a normal part of child development, and the strongest between the ages of 4 and 6. Setting rules and enforcing them teaches the child that he or she is equal in worth but not equal in authority. Then the child feel sage and secure and can be a kid again. Believe it or not, it’s frightening for childr en to realize they are in charge of a situation. Inup-side-down families when parents back down from rules they set, children become very insecure, anxious, and out of control. They don’t trust their parents to protect them. Parents should follow these tips to avoid the situation and keep control. Be a leader. Parents cannot guide a child and seek his or her approval of their decisions at the same time. Don’t say it’s time for bed. OK? Instead say it’s time for bed kids. Don’t make rules quickly and then c hange them. It’s very important to be consistent. Once you make a rule stick to it. Pay less attention to your children when their behavior is bad, and more when it is good. Do not reward bad behavior by giving extra attention to it. Instead save your attention for when the child acts appropriately. Don’t allow your kids to call you by your first name. This removes the authority figure in a child’s life. Children need parents not another friend.Part B. Listening comprehension.1. Statements. Directions. In this part of the test you will hear several short statements. These statements will be spoken only once, and you will not find them written on the paper. So you must listen carefully. When you hear a statement read the answer choices and decide which one is closest in meaning to the statement you have heard. Then write the letter of theanswer you have chosen in the corresponding space in your answer booklet. Now let’s begin with question number one.1) Do you think I could borrow your car to go grocery shopping? The supermarkets outside the city are so much cheaper than the one by the school.2) I got lost on my waited hotel in Boston last Sunday morning. I don’t know how I did it. I have been there a million times.3) Professor Avril sure was acting strangely in his morning class. He was talking so quietly and then not giving us any home work.4) I am sorry sir. But you are allowed only one piece of luggage on the plane. You will have to check one of the suit cases at the luggage counter.5) You wer en’t in class this morning. So you probably haven’t heard that the deadline has been extended a week.6) Are you going to the store? Well, I am low on laundry detergent, I forgot to buy some when I was at the supermarket yesterday afternoon.7) I just ca lled the travel agent. It’s all set. In the first week of next month, I am heading for the beach for an entire week.8) I worked very hard on my research paper. But the professor said that I made many broad claims that won’t support it enough.9) You say you really like those abstract paintings we saw in our art history class today, but I guess it’s something I haven’t acquired a taste for yet.10) You will be staying at the Hilton, right across the street from the conference center. But I am at the Royal Hotel 6 miles away.中级口译听力教程第三版8AAn intermediate course of English listening. Third edition.Sample test one.Part B. Listening comprehension. 2. Talks and conversations. Directions: In this part of the test you will hear several short talks and conversations. After each of these you will hear a few questions. Listen carefully because you will hear the talk or conversation and the questions only once. When you hear a question, read the four answer choices and choose the best answer to that question. Then write the letter of the answer you have chosen in the corresponding space in your answer booklet.Questions 11 to 14 are based on the following talk.Community service is an important component of education here at our university. We encourage all students to volunteer for at least one community activity before they graduate.A new community program called one-on-one helps elementary students who fallen behind. You education majors might be especially interested in it, because it offers the opportunity to do some teaching, that is tutoring in math and English. You’d have to volunteer 2 hours a week for one semester. You can choose to help a child with math, English, or both. Half hour lessons are fine, so you could do a half hour of each subject 2 days a week. Professor Doge will act as mentor to the tutors. He will be available to help you with lesson plans or to offer suggestions for activities. He has office hours every Tuesday and Thursday afternoon. You can sign up for the program with him and begin the tutoring next week. I am sure you will enjoy this community service and you will gain valuable experience at the same time. It looks good on your resume too, showing that you had experience with children, and that you care about your community. If you like to sign up or if you have any questions stop by professor Doge’s office this week.Questions:11) What is the purpose of this talk?12) What is the purpose of the program described by the man?13) What does professor Doge do?14) What should students interested in the tutorial do?Questions 15 to 21 are based on the following 2 talks.W: Well, I went away to college when I was 17. I had never lived away from my parents before. And I was really looking forward to it. But I was also scared because I was leaving my friends behind. And I didn’t know anyone when I first arrived. I lived in a really big dormitory and shared a room with 2 other girls. I guess the thing I learn the most was how to get long with others. You know how to respect other peo ple’s opinions and properties, stuff like that. At home I don’t always have my own room. This was the first time I’d have to live with other people in the same room. We were all really different. I mean our personalities and life styles were completely opposite in some ways. Anyway, at first it really caused problems, but we learned how to get along living in those tight cordors, three 17 years olds live in one room. Can you imagine? I am surprised we survived at all.M: I think for myself. The hardest thing was learning how to manage my own time better. I used to stay up late watching TV a lot, didn’t eat well, often went to class unprepared, and things like that. My grades were really suffering, and I could hardly keep my eyes open in class. It was a drag. Somehow, midway through the semester, I changed and started to do well. Organizing my time was a real challenge. In high school I didn’t have to worry. I had the same schedule everyday. And at night my parents were pushing me to study. But it’s different when you go away to college. You have to learn to take responsibility for your actions. No one is going to tell you what to do. You have to figure it out for yourself.Questions:15) How old was the woman when she went away to college?16) Why did she feel scared when she first arrived at the college?17) The women mentions that she learned several things at college, which of the following is not one of these things?18) Which was the most difficult thing for the man when he went away to college?19) Which of the following statements is not true as to his performance when he first arrived at college?20) When did he change and start to improve?21) According to the man what’s the thing you have to learn when you go away to college? Questions 22 to 26 are based on the following conversation.M: I just found out that my parents are moving.W: Mm, are you surprised?M: Well, not really. They’ve been trying to sell their house for 6 months to a year now.W: Oh, well, I thought they liked where they were.M: They do. They love it. But they are getting older. Dad wants to live in a smaller town. And mom says she is sick and tired of the fast pace and taking care of the house, you know.W: Mm. So where are they going to move?M: I can not believe this.W: What?M: They are going to Mexico. Can you believe it?W: Oh, my Gosh. You are kidding.M: Nope. They are going to San Miguel De Olanda. It’s a gorgeous little town in mountains. W: Wow, I have never heard of it.M: It’s about 115 miles northwe st of Mexico city.W: Wow, do your parents speak Spanish?M: No, but they are going to learn.W: Wow, that is a big change. Why don’t they stay in the US?M: Well, they always want to live abroad. Now that they are retired they finally get to do it. And my dad, he adores Mexico. He has been there 6 or 7 times at least.W: Wow, sounds like this is going to be quite an adventure.M: It should be. In San Miguel it is stunning. The government has made sure that there are no new buildings ever built there. So that the traditional feeling of the town. Wow, it’s been preserved. Oh, and they made pottery there, which is perfect for my mother, because she collects the stuff.W: Oh, that’s great for her. So I guess now you are going to have a place to stay in M exico. M: Yeah.W: And a place for your friends to come and visit in Mexico.M: Well, if my friends are nice to me, I suppose something could be arranged. Did you have anybody in particular in mind?W: Oh, very funny. So when exactly are they moving?M: In a couple of months. They have to pack up and take care of all the business here. I am going to help them with the move. I may even try to stay a couple of months if I can swing the time.Questions:22) Why is the man not really surprised at his par ents’ moving?23) The man mentions several reasons to explain why his parents are moving, which of the following is not one of the reasons?24) Where his parents planning to move?25) According to the conversation which of the following statement is not true?26) When exactly are they moving?Questions 27 to 30 are based on the following talk.OK. Let’s talk a little bit today about Steve Jobs, founder of Apple Computer. Jobs, a college drop out, a drop out who then goes on to start a revolutionary computer company, that changed the way the world perceive the computer and its role in society. Steve jobs believed, I should say strongly believed that the computer should and would become a tool for the everyday person. In his own words, he says, quote, we started it out to get a computer in the hands of everyday people. And we succeeded beyond the wildest dreams. And succeed he did, in 1977 the world’s first mass marketed personal computer, the apple two, came out. Hundreds and hundreds of thousands were sold. Other companies sprang up. And by 1985 there were 38 million computers in the world. In the year 2000, that number climbed to 557 million. In millions of homes across the globe, we communicate by computer, we play games, we get and give information, we shop, we work, we organize our personal finances, all done on a personal everyday home computer. Now behind Jobs’ belief that the computer should made available to the everyday person, was a true underlined belief in technology, that technology could be used to better our lives. The seventies saw real revolution in technology, but people like Steve Jobs were motivated by more than just the need to be involved in the technological revolution. He wanted to shape it. Jobs believed that it’s important to comb ine technology and art to be creative. With this kind of thinking it’s not too surprising to see why the macintosh has become a favorite among artists, graphic designers, professionals in the publishing and video and animation industries. Jobs says, quote, the macintosh turned out so well because the people working on it were musicians, artists, poets, and historians, who also happen to be excellent computer scientists. So Jobs believed in technology. He believed it could be made available to everyone, and he believed that it could be used as a tool for creativity. He was certainly a pioneer.Questions:27) Which of the following statements is not true about Steve Jobs?28) In which year was the first mass marketed personal computer produced?29) How many computers were there in the world in the year of 2000?30) What was Steve Jobs true underlined belief?Part C. Listening and translation.1. Sentence translation. Directions: Listen and translate each sentence you have heard into Chinese. Then write it in the space given below.1) It’s very difficult to quit smoking, which is why it is better not to start smoking in the first place. Doctors often say smoking kills.2) Most of the people I know are interested in the proposed tax reform being debated in the congress. Because they hope it will lower taxes for them.3) If more companies provide child’s care facilities at work, they will really help mothers who had to work outside of their homes.4) You shouldn’t be worried about making new friends. It w ill happen gradually. By this time next year I am sure you will have made many new friends5) There are more high school drop outs than before. Thus there are more unqualified young people looking for jobs than there used to be.2. Passage translation. Directions: Listen and translate each passage you have heard intoChinese. Then write it in the space given below. You may take notes while you are listening.1) You know the one issue that I feel the strongest about is the environment. Well, maybe it’sa little bit expensive to change our ways, but we have to try. We need to take care of the world we live in. So I think we can all do small things like recycle plastics and be careful not to waste water and electricity. You know what they say. We only have one world so we shouldn’t mess it up.2) For me freedom speech is very important. We should always be allowed to say what we believe, especially now. You know that people want to send to the internet, they want to limit what we have access to our computers. Well, I don’t agree with that at all. Of course I know it’s a tricky question, where do you draw the line on what should be controlled? What limit should be placed on our freedom of speech? I suppose there have to be some limits set, but I say the fewer the better. Maybe the best thing is just set aside everything on a case by case bases.。

批处理(又称cmd.exe/.bat)批处理(Batch)，也称为批处理脚本。

顾名思义，批处理就是对某对象进行批量的处理。

批处理文件的扩展名为bat。

目前比较常见的批处理包含两类：DOS批处理和PS批处理。

PS批处理是基于强大的图片编辑软件Photoshop的，用来批量处理图片的脚本；而DOS批处理则是基于DOS命令的，用来自动地批量地执行DOS命令以实现特定操作的脚本。

DOS批处理释义批处理是一种简化的脚本语言，也称作宏。

它应用于DOS和Windows系统中，它是由DOS或者Windows系统内嵌的命令解释器（通常是COMMAND. COM或者CMD.EXE）解批处理文件图标释运行。

类似于Unix中的Shell脚本。

批处理文件具有.bat或者.cmd的扩展批处理窗口名，其最简单的例子，是逐行书写在命令行中会用到的各种命令。

更复杂的情况，需要使用if，for，goto等命令控制程序的运行过程，如同C，Basic等中高级语言一样。

如果需要实现更复杂的应用，利用外部程序是必要的，这包括系统本身提供的外部命令和第三方提供的工具或者软件。

批处理文件，或称为批处理程序，是由一条条的DOS命令组成的普通文本文件，可以用记事本直接编辑或用DOS命令创建，也可以用DOS下的文本编辑器Edit.exe来编辑。

在“命令提示”下键入批处理文件的名称，或者双击该批处理文件，系统就会调用Cmd.exe运行该批处理程序。

一般情况下，每条命令占据一行；当然也可以将多条命令用特定符号（如：&、&&、|、||等）分隔后写入同一行中；还有的情况就是像if、for等较高级的命令则要占据几行甚至几十几百行的空间。

系统在解释运行批处理程序时，首先扫描整个批处理程序，然后从第一行代码开始向下逐句执行所有的命令，直至程序结尾或遇见exit命令或出错意外退出。

简单批处理命令简介echo 命令打开回显或关闭请求回显功能，或显示消息。
