The YR1 is an industrial robot.(This is the YR1, an industrial robot.)Industrial robots have many uses.This kind of robot is usually used for high precision assembly or metal work.The YR1 is made by a Japanese company, Yamashita Ltd.Yamashita is located in Tokyo, Japan.(The first YR1 was made in Japan in 1997. The YR1 was developed by Yamashita Ltd, a Japanese company.)YR1 is used on assembly lines, such as this one at Federal Motors. Federal Motors makes cars. (Federal Motors manufactures cars.)The YR1 is used for welding cars on the assembly line.(At Federal Motors, the YR1 robot is used for welding cars.)Many YR1 robots have been sold to the automobile industry.(Federal Motors is an automobile company. it makes many kinds of motor vehicles, such as cars, trucks and vans. This is one of the assembly lines at Federal Motors, an automobile company located in the United States.) In 1997, 15 units were bought by Federal Motors.Those units are now being used to do the work that 60 workers used to do. The robots work faster than human workers and they make fewer mistakes. The automobile industry has bought many industrial robots, such as the YR1.In 1997, 5,000 YR1 were made by Yamashita.Of those 5,000 robots, 50% were sold in Japan.25% were sold in the US. 10% were sold in Europe.(50% of the 5,000 robots that were made in 1997 were sold in Japan. 25% were exported to the US. 10% were sold in Europe. The rest were exported to other markets around the world.)In 1997, 50% of the YR1s manufactured by Yamashita were exported to other countries.The rest were sold in the highly competitive domestic market.In the past few years, worldwide sales of the YR1 and other robots have rapidly increased.If free trade continues, Yamashita’s future looks good.●OA-X ComputerThis is the OA-X. The OA-X is a computer.(This is the OA-X, it is a computer designed to increase efficiency.) It comes with lots of useful software.It has many uses.(It is easy to use and it has a variety of uses.)Some of its uses include word processing, communications and spreadsheets.This is Ace Ltd, a sporting goods company, located in the USA.Ace is one of the companies which bought OA-X computers in 1998.At Ace, the OA-X is used for word processing, communications and spreadsheets.Ace is using the OA-X to cut costs and improve office efficiency. Advanced Technologies is the maker of the OA-X computer.(The OA-X is manufactured and sold by Advanced Technologies Incorporated.)(The OA-X is made by Advanced Technologies.)The OA-X computer is an American product.(The OA-X computer is an American product, though many of its component parts are imported.)Advanced Technologies is located in California, near San Francisco.

They said their market was open.)Without more facts, it is difficult to decide the real reason.Trade friction is a difficult issue for every one involved.4. Product Comparisons●The EpicThis is the Epic.(The Epic is an American car.)It’s built by Federal Motors, an American company.Federal Motors introduced this model 5 years ago and designed especially for commuters.Recently it has become very popular. Compared to last year, its sales are up by more than 20%.Its sporty design and excellent fuel efficiency have contributed to its success.Customer satisfaction ratings have put it on the top 10 for the past few years.Its advanced design and light weight are a product of the world’s most advanced engine technology.It’s the most fuel efficient car of any American made car.The Epic gets 44 miles per gallon on the highway and 32 miles per gallon in city traffic.It costs around $18,000. At $18,000, it is a good buy.It is well engineered, and is reported to be the most trouble free of any American made car.(In terms of quality and dependability, the Epic is considered to be the best made American car in its price range.)The Epic generally goes about 80,000 miles before it needs major repairs. (The Epic is built to last around 80,000 miles before problems begin to appear.)According to a recent study, fewer Epic owners had problems in the first six months of ownership than owners of any other car.It is also backed by an excellent warranty program.Its warranty covers all parts and labor for five years or 50,000 miles. As a result, it has proven to be a good choice for people who spend lots of time commuting to work each day.Five years ago, Federal Motors was losing a lot of money, and its market share was falling rapidly.Many of its cars had to be recalled for safety problems, and three were many customer complaints about quality.When the Epic was introduced, sales were slow at first because the public had lost confidence in Federal Motors.Gradually however, the car began to earn a good reputation, and sales improved.As a result, Federal Motors has been able to compete more successfully with foreign competitors.Their main challenge now is to improve their dealer network.Their sales people are often criticized for poor sales practices.●The SXThis is the Yamada SX.50% of the Yamada sold in the US are imported from Japan, the other half are made in the US.The base price of the SX is around $14,000.It comes with a 36 month or 36,000 mile warranty.The SX is one of the biggest Japanese cars in its class. It has room for 5 big adults.In terms of fuel economy, the SX gets about 38 miles per gallon on the highway, which is better than average for its class.Auto industry studies indicate that the SX is trouble free for around 60,000 miles.An important sales point is that its maintenance and service costs are generally lower than the industry average.This is because Yamada has established a dealer network that provides thebest service support in the industry.According to several surveys, the SX has been number one in customer satisfaction for 3 years.(For 3 years, it is one the top customer satisfaction rating in several surveys.)As a result, the SX is now the best selling car in the US.●The AriaThis is the Union Aria. It was first introduced into the US in the late 1980s by Union Motors, a European company.It’s a well built car, and it has a good reputation.(It’s a solid, well made car with a good reputation for passenger comfort and safety.)The Aria is paid about $28,000.It comes equipped with lots of standard features, such as AM/FM radio and air conditioning.The Aria has more passenger room than any other car in its class.It has plenty of room for a growing family.It gets 34 miles per gallon on the highway and 22 miles per gallon in the city.It comes with a powerful engine that can pull a boat or a trailer with ease.It’s rated high in terms of dependability.In generally goes about 60,000 miles before it needs any major repairs. Unfortunately, the cost of parts and services are higher than average. In terms of safety, the Aria has the best record of any car.In crash tests, the Aria has consistently outperformed all other cars. In general, its size, power, and excellent safety record make it a good family car.Though it’s an excellent family car, its sales have remained flat for the past few years.Some people say it’s too expensive, others say that its design is uninteresting.If sales don’t improve, major changes will have to be made.●A ComparisonLet’s compare these three automobiles.First, the Federal Epic is the most fuel efficient.(In terms of fuel economy, the Epic gets better mileage than either theUnion Aria or the Yamada SX.)The Aria doesn’t get as many miles per gallon as the other two cars, but it’s bigger and its engine is more powerful.As you can see in this comparison, the Aria is the most expensive. (As for price, the Aria costs more than the other two.)It costs twice as much as the SX.The least expensive of these three cars is the SX.(Priced at $14,000, the SX is the least expensive of these three models.) It's about half the price of the Aria and nearly 25% less than the Epic. The Epic costs $4,000 more than the SX.As for size, the Aria is the biggest of the three.(In terms of size, the Aria is bigger than the other two.)The Epic, which seats 4 adults, is the smallest.The SX is larger than the Epic, but it has slightly less passenger room than the Aria.(The SX is bigger than the Epic, but it isn’t quite as big or powerful as the Aria.)In terms of low cost maintenance and durability, the Epic has the best record.It is very economical.It has a better performance record than either the Aria or the SX. Compared to both the other cars, it goes 20,000 more miles before it needs repairs.To summarize, each car has its advantages.The Aria may be the best buy for a growing family, though it's a bit expensive.For the commuter, the Epic is probably the best choice.Its fuel economy and excellent dependability give it the advantage. For buyers who like a low purchase price and who want a slightly bigger car, the SX is probably the best value.It isn’t as small as the Epic and it costs less。
DynEd英语
最忠实的英语家教,最亲和的教学氛围,最省钱的学习渠道,最有效的学习方式,全家人共同学习的乐趣.一切尽在戴耐德.不在戴耐德,就在去戴耐德的路上.半年克服哑吧英语,一年成就流利英语每天一百八,外教请到家. 全新的外语模拟教学环境在学习中体会亲子教育的乐趣.你想请一个外教做二十四小时的贴身家庭家庭老师吗如何开好英语学习的第一关好的老师是引领你学好英语的关键1,你的英语学好了吗,从初中到大学,甚至硕士博士,我们拿到了很多英语学习的证书,我们是不是英语学好了呢,我认为判断英语学好没有的标准不是你考了多少分,是看你能否流利的用英语进行交流。
2,英语是知识还是技能从我们的英语启蒙开始,我们的老师教授我们英语学习,其学习的方式更多的当成一种知识在传授,用一种灌输式的,要求学生死记硬背的去学习。
记单词语法,背句型课文。
考试一考完,一过就忘了。
为什么,指导方针有根本的错误,以武汉为例,华师一附中,很多高中生都考过了四级,但是我们的大学生,有人上大学后,考四级的成绩是一次比一次低,第一考,主要是得益于高中的英语基础,后来,就慢慢越高越低了。
原因是学习没有恒心坚持。
英语是一门语言,语言是用来交流思想的工具,是我们用来阅读的工具,它的实质是一项技能,对于技能的掌握,我们应该遵循哪些规律呢,就象打球,打的多了,你才会打的更好。
作为一门技能的英语,我们能做的就是多练习。
多开口。
别人不开口,你可以自己开口,面对电脑,把你的说的英语录下来,与一旁的原声进行对比,不断提高。
3,谁的语言学习能力更强与一个五岁的小孩相比,我们从初中开始学英语,到上了大学,谁的语言学习能力更强呢?答案是明显的:我们学习语言肯定没有小孩子学的快。
有人把它归结为文化的影响,认为是我们的某种中国文化思维方式束缚了我们对英语的学习。
这种想法肯定是错误的。
有人认为是我们没有一个学习英语的语言环境,这种说法有一定的道理。
但是我们自己可以创造言语学习的环境,就象许多大学的英语角一样,但是英语角的举办是有时间限制的,只有自己去创造语言环境。
DBUnit入门级教程
DBUnit数据库单元测试前言(出生地和原因)DBUnit是Junit家族中的一员,是专门用来测试数据库的工具。
本文将对其应用进行一个简单的介绍,帮助学习使用该工具。
DBUnit是对Junit的一个扩展,提供测试子类TestCase(对接触过Junit的人比较熟悉,如果没接触过,只要记住这个类名称就可以了),其关键类继承了Junit 的TestCase,并对其函数进行了重写和接口扩展工作,为对数据库的测试提供了很大的便利。
概述(DBUnit的便利)在数据库测试中,主要是测试程序中写的Query语句是否正确执行的工作。
在以前的实际应用中,在自己进行测试时,需要自己写入数据,执行后需查看数据是否正确,清理不正确数据,然后继续修改数据,已完成Query的正确性。
如果使用数据库IDE可能还会方便一点,但是其简单却繁琐的工作会耽误很多时间。
DBUnit则会帮助你完成这一部分对数据库数据的操作,即提供单元测试框架,并帮助测试者完成对数据的自动写入、正确性验证、数据清理等工作。
当然,你也可以完全脱离测试的目的,使用其里面的方法完成一些其他工作(如数据库数据的自动载入、备份等)。
准备(用到的jar包)使用前除了必须的Junit库之外,还需要其他几个包。
如图1.0图1.0 jar包DBUnit使用了一些日志功能,所以需用到后三个包内的一些方法。
核心(大量的xml文件)既然要对数据库进行自动载入、验证等工作,则必须需要数据。
但是数据从哪里来,这是使用前必须了解的事情。
一些使用DBUnit很长时间的程序猿会评价到:DBunit很好用,就是对xml 文件的操作太多。
从这句话就可以看出,xml文件对该工具的重要性。
没错,我们的数据来源就是xml文件。
一般情况下,对于一个用例,会用到两个xml文件:Query执行前数据库数据和正确执行后的数据库数据。
当然,你也可以加一个数据库备份数据文件,随人而定。
不过在这里提出xml文件可能会对初学者有些干扰,不过不用急,图1.1会先介绍用到的xml的文件结构,还有你只要先知道这些结构并记住,数据都是来自这些文件即可。

戴耐德英语学习指导
DynEd学习指导一.什么是DynEd?DynEd 是Dynamic Education 的缩写,代表美国DynEd多媒体教育公司。
该公司享誉全球,1987年成功开发出世界上第一个多媒体英语教学软件,随后该公司的多项产品在评比中获奖,其中包括世界级权威专业机构——美国发展培训协会颁发的优秀网络课程证书。
为了提高英语教学水平,本中心于2003年3月引进该公司的多媒体英语教学软件(以下简称DynEd),收到良好效果。
二、为什么学习动态英语DynEd?“传统”的外语有三大缺陷:1) 教学重点是整体,不是满足个人需求。
例如,少数人发音不准,教师“爱莫能助”,原因很简单,不能为此占用大家的时间。
2) 教学活动是规范性行为,不是自主性行为。
例如,进行听力训练时,无论基础好坏,都得统一步调,学习同一内容。
3) 教师的主要责任是传授学习方法,不是帮助学生解决具体问题。
不少学生习惯于边听磁带边阅读文字材料。
然而,由于时间和精力有限,教师很难针对个人提供具体的帮助和指导。
采用DynEd软件可分别有效解决上述问题。
第一,由于DynEd 软件能提供标准语音示范和先进的语音识别功能,它能在较大程度上“替”老师上课,使个性化学习需求得到满足。
第二,借助DynEd软件的互动功能,学生能充分发挥学习自主性。
同样是进行听力训练,教师可让学生根据自己的实际水平从DynEd软件系列中选择不同的学习内容。
由于该系统具有录音、播放、对话和单元测试等多种功能,学习者可自主选择不同的学习方式。
第三,借助DynEd软件的教学管理系统,教师能详细了解学生的学习习惯和方法,及时帮助他们调整学习策略。
三、采用DynEd后教学模式有何变化?如下图所示,传统的英语教学是“单轨制”模式:采用DynEd软件后,教学模式由“单轨制”转变为“双轨制”,在原有的基础上增加了具有网络和现代多媒体支撑的“第二课堂”。
(图2)采用DynEd后的教学模式本中心引进DynEd 软件是一套由9个软件组成的课程体系。
DynEd英语学习情况问答与课程简介
DynEd英语学习情况问答与课程简介一、什么是DynEd英语美国斯坦福大学与BBC广播公司、牛津大学出版社等合作开发的DynEd英语,是通过学前测试系统确定学员适合的学习起点后,采用多媒体教学(人机互动的教学方式)和面授课辅导相结合方式进行学习的现代英语培训模式。
二、为什么要引进DynEd英语学员经过水平测试后,DynEd英语将单机版学习课程安装在参加学习人员指定的电脑上,借助网络学习相应级别英语课程,有利于扩大业余英语学习的覆盖面,有利于英语业余学习的规范化管理,有利于提高培训资源的利用效率。

因故延误面授课,可到其它同级别班补课。
DynEd 英语学习将作为总局系统长期开展的英语业余学习形式,报名人员可结合本人工作实际选择合适时间开始学习。
五、DynEd英语学习是如何管理的学员每次开始学习在线注册时,上一次学习记录将会被传送到DynEd英语管理系统,DynEd英语每两周出具一份学习进程报告,显示学员的学习进度等学习数据。
DynEd英语会将此报告适时反馈给本人和单位,以提醒、督促、监督学员的学习。
六、DynEd英语费用情况如何学习DynEd英语前的水平测试将决定学员起始级别,每人每级别学习费用1060元(含面授课),软件安装费每人50元。

英语课件dyned安装常见问题
WEB英语课件DynEd安装常见问题WEB英语课件安装时总会出现这样那样的问题,我把我安装时出现的安装问题及修复方式总结如下。
本篇仅是我个人经验所得,并非必然适用于所有情况。
希望买家注意。
若是你有其它问题实在解决不了的,可以联系本人。
光驱无法读盘WEB英语课件全套八个级别八张光盘,还有测试光盘一张,一共是九张光盘。
其中DVD光盘7张,CD光盘2两张。
本人用的尽是先锋A+级光盘,光盘质量绝对可以安心。
而且发货前本人会用光驱全数从头测试一遍,肯定没有问题后才会发货。
但不保证有快递时挤压引发光盘变形而无法读的现象发生。
解决办法:首先确认你的光驱是DVD光驱,而不是CD光驱。
另外本人连年的装机经验发现,一些杂牌的光驱,特别是一些深圳工包的翻新光驱,对刻录盘的支持性不是很好。
常出现别的光驱能读,而该光驱识别不了的现象。
你可以先用一台好的电脑从光盘里拷取数据后,再用移动硬盘之类的再将课件全数拷回该电脑即可。
请尽可能多试几台电脑,多试几个光驱,若是真的是光盘质量问题引发的而致使无法读盘的,请联系店家,协商进行处置。
一,似乎这是你第一次学习WEB英语全套八个级别,八张光盘,还有测试光盘一张,一共九张光盘。
每张光盘对应有一个帐号,一个密码。
出现该提示框,一般是因为你输入的帐号及密码不对。
所以请确认你输入的帐号和密码是该级别所对应的。
另外一种极端情况是,明明你输入的帐号和密码是对的,可是仍是会出现该提示框。
具体原因尚不清楚,一般可以通过删除干净(同时要将C盘下Program Files文件夹的DynEd文件夹删掉),再到光盘里面从头拷一遍即可以解决。
若是你想节省时间,删课件时,该级别的课件除content这个文件夹(容易最大的一个文件夹)不用删外,其它文件删掉后,从头到光盘里面再拷一次。
二,没有学习记录本人卖的WEB英语是破解版的,除没有学习记录同步功能外,其它的都是跟WEB培训内部一样。
学习记录同步功能是给tutor看的,以方便她指导你进一步学习。
关于DYNED经验技巧总结
关于DYNED经验技巧总结关于DYNED 的经验技巧总结最重要的一点,不要刷TLS 和TM 两个模块,这两个是选修内容,结业对这两个模块不做要求;首先,来规定一下我后面的用词。
屏幕最下面的一排按键,从左到右依次为:ESC;录音键;回放键;向前键;重复键;暂停键;向后键;ABC 键1、千万不要点ABC 键,否则你的智能辅导分会狂掉。
想要显示文字有另一张方法,就是点“向前”键,然后电脑就会显示前一句的文字,趁它没消失的时候,点“录音”键,这时文字就会定住。
这种方法不会掉智能辅导,但是会掉水准。
2、关于进度:(1)时间是影响进度的首要因素。
每遍PRESENTATION 的时间太长或太少都对进度增长不利。
以DBE为例,3 分钟的PRESENTATION,4 分钟听完只能增长2%的进度,20 分钟听完也只能增长13%的进度,但10 分钟听完可以增长10%。
所以,建议PRESENTATION 都用10 分钟左右刷一遍(NDE 可以15 分钟,要多多使用录音、回放和重复键),这样的时间利用率最高。
(2)关于水准:水准是影响进度增长快慢的重要因素。
在课程记录里,每次PRESENTATION 和做题的水准都不一样,水准一般会随着做题次数逐渐提高,直到3.0。
水准越高,进度增长越快。
以FIB 为例,水准为0.8 时,10 分钟可以进度增长6%,但水准为3.0 时,10 分钟可以进度增长17%。
所以,对于那些一心只想刷进度的同学们,可以在前几次水准低的时候,4 分钟一遍地刷PRESENTATION,等水准达到2.0 之后再回到10 分钟一遍。
3、关于智能辅导:对于智能辅导分,大家一定要有针对性,要知道自己还缺哪几个方面的智能分,怎么样才能刷上去。
在此,我把我所发现的一些分享给大家。
(1)录音功能用的好。
(你没有做足够的录音练习)(2)重复键使用的好。
(请更多使用重复键)这两个是大家一定要会的技巧。
如果想要这4 分(如果你有括号里的这两句,那么就有8 分的上升空间),你就要有牺牲精神,一个3 分钟的PRESENTATION,你要拿出来30-40 分钟来刷一遍,电脑念一句,然后你就录音,回放,重复,录音,回放,重复……这样每句3-4 轮(电脑能够记录的是每句录音5 次)。

DynEd 学习得分提高攻略
DynEd 学习得分提高攻略在dyned使用过程中,大家最烦得就是这个学习得分,为什么自己总是负分而别人得分都很高,为什么自己已经很好学了得分还是负的。
其实刷分还是有技巧的,下面介绍介绍经验,仅供参考首先要明确那些项目可以加分,一般每一项加分也对应着一项扣分的,扣分比较惨的,而且是倒扣。
如图所示,咱们逐项分析。
(1)在语音识别练习中,回听键使用得好。
根据助教介绍的正规的学习方法,在做SR(即语音识别练习)时,应该是识别过之后用重复键(圆圈+箭头那个键)听原声,然后用回听键(画着耳机的那个键)听自己刚刚录入的声音,目的是听自己哪里讲的不如原声好,然后用录音键(画着mic的那个键)录入自己听了原声改进后的声音,然后重复以上过程直到听着自己的声音跟原声完全相同……是不是听起来很麻烦>。
<~我反正是没这样做。
其实只要在每次识别后用一两下回听键就好了,每次都这么做,不久就可以出现这一加分。
2分到手~如果SR时从来不用回听键,小心出现回听键使用不足而倒扣2分。
(2)重复键使用得好,请继续认真练习听。
重复键就是一个圆圈上边带箭头的那个键。
这个键不太好刷(个人认为),而且非常容易丢掉(本来有这项加分突然就没了)。
应该是在presentation课程中(是否为presentation 看注释,presentation基本上就是每单元讲课文的那个)使用,其他课程中使用只记次数不记入有效次数,不过个人认为在SR中也管用,但是像那种选词填空的课程里就没用了。
每个句子有效重复次数为5遍。
提到有效次数,不得不说说助教学姐讲过的一个说法,就是重复键,回听键,录音功能这三个键加上你所听的总得句子数,算分的时候这四个量内部存在比例关系,符合比例则出现该项加分,在比例中出现的重复键使用次数就是有效次数而不是助教那里显示的那个重复键使用次数。
个人感觉这个说法不是很确定,详情还是咨询助教吧= =。
还是说有效次数吧,还有一个要求就是不能一个句子听到一半就按重复键,这样也是不算有效次数的。
DynEd教师管理端操作文档
DynEd教师管理端Records Manager操作文档1.DynEd教学理念●语言是一种技能传统的英语教学太过注重读写,而疏于听说能力的发展。
学生花费了大量的时间来背单词、记语法,不但学习得很辛苦,而且效果很差,最后还是无法自如地交流。
这是因为传统的英语教学把语言当成了一种知识。
而我们认为,语言是一种技能,我们应该把更多的时间用来练习。
就像运动员一样,他应该把大量的时间用来训练,而不是记忆。
●以“听”为引入,以“说”为重点从人类发展的角度来说,是先有的语言,后有的文字;从人的学习过程来说,是先呀呀学语,再读书写字;而语言本身的意义也在于交流。
所以DynEd坚持以“听”为引入,软件界面基本不出现文本,而是以音频+图示的形式展现,使大脑获得听觉和视觉的多元输入,增加大脑的反射区域而形成长效记忆;以“说”为重点,DynEd认为对课件内容的理解(Comprehension)是远远不够的,学生要达到掌握(Mastery)甚至条件反射(Automaticity),所以DynEd要求学生在学习课件的时候,要做大量的跟读及录音对比,而且DynEd提供了各种各样的语音识别、人机对话等练习活动。
最重要的是,学生在课堂上要有机会“说”,老师可以组织Oral Presentation,Role Play,Pair Work,Group Activity等形式多样的拓展活动,这就是DynEd 所提倡的自主学习+课堂拓展的混元教学模式。
●Practice Makes Perfect既然语言是一种技能,就需要不断地练习,那么练习什么、如何练习就至关重要。
DynEd强调可理解性输入,学生学习的内容难度要合适,使其有进步的空间。
针对语言习得的过程,DynEd提出了五个步骤:Familiarization,Recognition,Comprehension,Mastery,Automaticity,而要想获得最终的Automaticity,学生需要达到一定的学习时间和学习频率。

刷dyned技巧
为什么我的眼里饱含泪水?因为我的DYNED刷不完。
【网上搜罗的各种刷呆小技巧汇总】来源:程帆²º¹²的日志AL Advanced Listening这个课程是最让我痛苦的了,一堆教授没完没了地说一些过时的让我们完全不感兴趣的话题,听到最后精神处于将要崩溃状。
不过在我即将把所有课程听完时,才发现了一个堪称绝妙的方法。
有兴趣一定要试试,非常神奇,原来40分钟刷一个part,后来径直缩短到20分钟左右。
先不要听Presentation,一上来先听Language Skills,而且只听第一个Vocabulary。
一般给出的单词或者词组猜猜蒙蒙再加上本来就认识的,基本上不会错多少。
当把所有词都挺过来后,就不要听他念题目了,直接疯狂地点击上面的标题栏,就是对话框最上面的蓝条,到问题的时候停下来选,其余时候就点那个条pass掉那堆题干。
我粗率统计,大概在6~10分钟内就可以听到100%。
这时候再返回来听Pr esentation,注意关键在这里,每个lecture前都会有个介绍,例如:Lecture 1 Dealing With Stress……Listening to the question……这时候按回退键,返回去继续听这一段话,大概3,4次左右的重复,就可以在完全不用听内容的情况下,轻松把进度刷到100%以上。
最后是Interactive Listening。
其实这个部分主要是看你做题的准确性。
所以我一般会仔细听一遍并打开字幕,把每一句都看明白,这样回答问题的准确性就比较高,刷的时间就会比较短。
一般听一两遍后就是重复的题目了,就可以用刷Vocabulary的方法,跳过演讲,直接选答案。
进程会非常快的~~~Clear Speech Works其实这个课程还是很容易刷的,因为要求是一共刷够5个小时,并且每个part都刷到,所以一般情况下只用听Video就OK了,听的时候可以干一点自己喜欢的事情,很快就过去咯!English By The Numbers这么多课程里,我觉得这个是最值得一听的。

The YR1 is an industrial robot.(This is the YR1, an industrial robot.)Industrial robots have many uses.This kind of robot is usually used for high precision assembly or metal work. The YR1 is made by a Japanese company, Yamashita Ltd.Yamashita is located in Tokyo, Japan.(The first YR1 was made in Japan in 1997. The YR1 was developed by Yamashita Ltd, a Japanese company.)YR1 is used on assembly lines, such as this one at Federal Motors.Federal Motors makes cars.

The OA-X is a computer.(This is the OA-X, it is a computer designed to increase efficiency.)It comes with lots of useful software.It has many uses.(It is easy to use and it has a variety of uses.)Some of its uses include word processing, communications and spreadsheets.This is Ace Ltd, a sporting goods company, located in the USA.Ace is one of the companies which bought OA-X computers in 1998.At Ace, the OA-X is used for word processing, communications and spreadsheets.Ace is using the OA-X to cut costs and improve office efficiency.Advanced Technologies is the maker of the OA-X computer.(The OA-X is manufactured and sold by Advanced Technologies Incorporated.)(The OA-X is made by Advanced Technologies.)The OA-X computer is an American product.(The OA-X computer is an American product, though many of its component parts are imported.)Advanced Technologies is located in California, near San Francisco.(Advanced Technologies is based in California, just south of San Francisco.)The company has an excellent reputation.(The company has an outstanding reputation for quality.)In recent years however, its sales have suffered because of strong competition from Japan.It has excellent products and competitive prices.(It has a highly trained work force and it uses the latest technology in the manufacturing process.)It also provides outstanding customer support.As a result, its products are highly rated.In 1998, Advanced Technologies sold 10,000 units.(Worldwide sales of the OA-X totaled 10,000 units in 1998.)The selling price for each unit was about 2,000 dollars.Sales were good in the major international markets, however in Japan, sales were poor. 75% of the units made in 1998 were sold in the United States.10% were sold in Canada and another 10% were sold in Europe.Only 2% of them were sold in Japan.The Americans complained, they said it was unfair.(The American said that this was because the Japanese markets were closed.)The Japanese said it was the American’s fault.(The Japanese said that the OA-X was poorly designed for the Japanese user. They said their market was open.)Without more facts, it is difficult to decide the real reason.Trade friction is a difficult issue for every one involved.4. Product Comparisons●The EpicThis is the Epic.(The Epic is an American car.)It’s built by Federal Motors, an American company.Federal Motors introduced this model 5 years ago and designed especially for commuters.Recently it has become very popular. Compared to last year, its sales are up by more than 20%.Its sporty design and excellent fuel efficiency have contributed to its success. Customer satisfaction ratings have put it on the top 10 for the past few years.Its advanced design and light weight are a product of the world’s most advanced engine technology.It’s the most fuel efficient car of any American made car.The Epic gets 44 miles per gallon on the highway and 32 miles per gallon in city traffic. It costs around $18,000. At $18,000, it is a good buy.It is well engineered, and is reported to be the most trouble free of any American madecar.(In terms of quality and dependability, the Epic is considered to be the best made American car in its price range.)The Epic generally goes about 80,000 miles before it needs major repairs.(The Epic is built to last around 80,000 miles before problems begin to appear.) According to a recent study, fewer Epic owners had problems in the first six months of ownership than owners of any other car.It is also backed by an excellent warranty program.Its warranty covers all parts and labor for five years or 50,000 miles.As a result, it has proven to be a good choice for people who spend lots of time commuting to work each day.Five years ago, Federal Motors was losing a lot of money, and its market share was falling rapidly.Many of its cars had to be recalled for safety problems, and three were many customer complaints about quality.When the Epic was introduced, sales were slow at first because the public had lost confidence in Federal Motors.Gradually however, the car began to earn a good reputation, and sales improved.As a result, Federal Motors has been able to compete more successfully with foreign competitors.Their main challenge now is to improve their dealer network.Their sales people are often criticized for poor sales practices.●The SXThis is the Yamada SX.50% of the Yamada sold in the US are imported from Japan, the other half are made in the US.The base price of the SX is around $14,000.It comes with a 36 month or 36,000 mile warranty.The SX is one of the biggest Japanese cars in its class. It has room for 5 big adults.In terms of fuel economy, the SX gets about 38 miles per gallon on the highway, which is better than average for its class.Auto industry studies indicate that the SX is trouble free for around 60,000 miles.An important sales point is that its maintenance and service costs are generally lower than the industry average.This is because Yamada has established a dealer network that provides the best service support in the industry.According to several surveys, the SX has been number one in customer satisfaction for 3 years.(For 3 years, it is one the top customer satisfaction rating in several surveys.)As a result, the SX is now the best selling car in the US.●The AriaThis is the Union Aria. It was first introduced into the US in the late 1980s by Union Motors, a European company.It’s a well built car, and it has a good reputation.(It’s a solid, well made car with a good reputation for passenger comfort and safety.) The Aria is paid about $28,000.It comes equipped with lots of standard features, such as AM/FM radio and air conditioning.The Aria has more passenger room than any other car in its class.It has plenty of room for a growing family.It gets 34 miles per gallon on the highway and 22 miles per gallon in the city.It comes with a powerful engine that can pull a boat or a trailer with ease.It’s rated high in terms of dependability.In generally goes about 60,000 miles before it needs any major repairs. Unfortunately, the cost of parts and services are higher than average.In terms of safety, the Aria has the best record of any car.In crash tests, the Aria has consistently outperformed all other cars.In general, its size, power, and excellent safety record make it a good family car. Though it’s an excellent family car, its sales have remained flat for th e past few years. Some people say it’s too expensive, others say that its design is uninteresting.If sales don’t improve, major changes will have to be made.●A ComparisonLet’s compare these three automobiles.First, the Federal Epic is the most fuel efficient.(In terms of fuel economy, the Epic gets better mileage than either the Union Aria or the Yamada SX.)The Aria doesn’t get as many miles per gallon as the other two cars, but it’s bigger and its engine is more powerful.As you can see in this comparison, the Aria is the most expensive.(As for price, the Aria costs more than the other two.)It costs twice as much as the SX.The least expensive of these three cars is the SX.(Priced at $14,000, the SX is the least expensive of these three models.)It's about half the price of the Aria and nearly 25% less than the Epic.The Epic costs $4,000 more than the SX.As for size, the Aria is the biggest of the three.(In terms of size, the Aria is bigger than the other two.)The Epic, which seats 4 adults, is the smallest.The SX is larger than the Epic, but it has slightly less passenger room than the Aria. (The SX is bigger than the Epic, but it isn’t quite as big or powerful as the Aria.)In terms of low cost maintenance and durability, the Epic has the best record.It is very economical.It has a better performance record than either the Aria or the SX.Compared to both the other cars, it goes 20,000 more miles before it needs repairs.To summarize, each car has its advantages.The Aria may be the best buy for a growing family, though it's a bit expensive.For the commuter, the Epic is probably the best choice.Its fuel economy and excellent dependability give it the advantage.For buyers who like a low purchase price and who want a slightly bigger car, the SX is probably the best value.It isn’t as small as the Epic and it costs less如有侵权请联系告知删除,感谢你们的配合!。
