V. Reading Comprehension:

Education in the United States is compulsory for children up to about the age of sixteen. Most young people stay in school longer than that . Most graduates continue their education at a college or university. Education for most young people in this country is free up to the time they graduate from high school. There are private schools, but most parents send their children to public schools, where students do not pay tuition. When young people go to college, however, they must pay tuition at a public university or a private university. University costs are going up a lot. Private universities have become very expensive because the government does not help the private schools.

Who pays? The parents of children in college may have to pay more, or often the students may have to find jobs. These students have to worry about assignments and grades and also about their jobs. If they work too much at their jobs, they may be absent from class or miss assignments or make too many errors on tests. They may even fail their courses and have to leave the university. For many students, the problem of getting an education is not a problem of homework and exams. They also have to make money to pay for tuition. And professors don't teach them how to do that!

It was not a good year. At harvest the crops did not bring as much as we had hoped. Yet even though times were hard, I couldn‘t wait any longer to ask, ―Daddy, may I have a violin of my own?‖Daddy‘s face looked sad. That night, and many following nights, I heard him pray, ―Lord, my daughter wants her own violin.‖

One evening we all sat around the table. I was doing my homework. Mother sewed, and Daddy wrote a letter to his friend, George Finkle, who was a fine violinist. As he wrote, Daddy read parts of his letter out loud to Mother. Weeks later I discovered he‘d written one line he didn‘t read aloud: ―Would you watch for a violin for my daughter? I can‘t pay much, but she enjoys music, and we‘d like her to have her own instrument.‖

At last the day arrived. I listened while Daddy made a phone call. He hung up and asked, ―Mary, do you want to go with me to visit Mr. Finkle?‖

―Sure,‖ I answered.

When we came to the fine, old house, a tall man, older than Daddy, opened the door. ―Come in! Mary, I‘ve been hearing things about you. Your daddy has arranged a big surprise for you!‖In the hall, he picked up a case, opened it, took out a violin, and he turned to Daddy. ―I found it in a pawnshop for seven dollars. It‘s a good violin. Mary should be able to make beautiful music with it.‖ Then he handed the violin to me. I noticed the tears in Daddy‘s eyes as I finally comprehended. It was mine! ―How beautiful!‖ I said barely breathing.

The day I carried my violin to school for my first lesson I was frantic. After class I practiced daily, feeling the warm wood fit under my chin like a part of my body.

Two years later, I graduated. I packed my cherished violin in its case and stepped into the grown-up world. More years passed. My violin made every move with us, and I carefully stored it away—briefly remembering how much I still loved it and promising myself to play it soon.

C

Leisure plays an important part in British life. There are four main reasons for this.

First of all, people spend less time working now than they used to, mostly due to the introduction of new technology in industry. The normal British working week is Monday to Friday, 9.00 am to 5.00 pm, although some people regularly work a few hours‘ overtime each week. Secondly, all working people get a minimum of two weeks‘paid holiday a year. In addition, there are six or more bank holidays a year when all banks and businesses are closed. In some cases the dates of these national holidays change from year to year and in different parts of Britain.

Another reason is that, thanks to modern medicine and higher living standards, people live longer now. This means that after retirement, people have quite a few years of leisure left. Nowadays a much higher proportion of the population is over sixty, but in this group there are more women than men.

Finally, fewer babies are born each year and the average family in Britain

has two children. This is one result of changing social attitudes. For example, many more married women now go out to work. The money they earn influences their leisure time. Even married women who do not go out to work have more time for interesting hobbies because most British homes have washing machines, vacuum cleaners and other labor-saving gadgets.

Nobody likes staying at home on a holiday if the weather is fine. Last August we decided to spend the day in the country. The only difficulty was that millions of other people had just the same idea. We moved out of the city slowly behind a long line of cars, but at last we came to a quiet country road and, after some time, stopped at a farm far from the town. We had brought plenty of food with us and we got it out of the car. Now everything was ready so we sat down near a path at the foot of a hill. It was quiet in the cool grass—until we heard bells ringing at the top of the hill. What we saw made us pick up our things and run back to our car as quickly as we could. There were about two hundred sheep coming towards us down the path!

Almost every family buys at least one copy of a newspaper every day. Some people subscribe to as many as two or three different newspapers. But why do people read newspaper?

Five years ago, news of important happenings?battles lost and won, kings or rules overthrown or killed?took months and even years to travel from one country to another. The news passed by word of mouth and was never accurate. Today we can read in our newspapers of important events that occur in faraway countries on the same day they happen.

Apart from supplying news from all over the world, newspapers give us a lot of other useful information. There are weather reports, radio, television and film guides, book reviews, stories, and, of course, advertisements. There are all sorts of advertisements. The bigger ones are put in by large companies to bring attention to their products. They pay the newspapers thousands of dollars for the advertising space, but it is worth the money for news of their products goes into almost every home in the country. For those who produce newspapers, advertisements are also very important. Money earned from advertisement makes it possible for them to sell their newspapers at a low price and still make a profit.

Newspapers often have information on gardening, cookery and fashion, as well as small

浅谈我对现代远程教育的认识

浅谈我对现代远程教育的认识 现代远程教育，是随着现代信息技术的发展而产生的一种新型教育形式，是构筑知识经济时代人们终身学习体系的主要手段。通常认为，远程教育已经历经三代：第一代是函授教育；第二代是广播电话教育；第三代的基本特征是利用计算机网络和多媒体技术，在数字信号环境下进行教学活动，被评为“现代远程教育”。 所谓远程教育或网络教育，就是在线学习或网络化学习，即在教育领域建立因特网平台，学习者通过计算机上网，通过网络进行学习的一种全新的学习方式。当然，这种学习方式离不开由多媒体网络学习资源、网上学习社区及网络技术平台构成的全新的网络学习环境。在网络学习环境中，汇集了大量的数据、档案资料、程序、教学软件、兴趣讨论组、新闻组等学习资源，形成一个高度综合集成的资源库。这些学习资源对所有人都是开放的。一方面，这些资源可以为成千上万的学习者同时使用，没有任何限制；另一方面，所有学习者都可以发表自己的看法，将自己的资源加入到网络资源库中，供大家共享。 现代远程教育，是近年来随着互连网的发展而产生的新鲜事物，我觉得现代远程教育的优点在于，教师的讲授和学员的学习，可以在不同地点同时进行，师生之间可以进行充分的交流；学员能够根据自已的需要自主安排学习时间和地点，灵活程度很高，学习中的问题也能比较及时的得到答解；现代远程教育手段与传统的培训相比更有利于个体化学习，以学员自学为主.与传统培训相比，远程教育占有一定的优势.但要有实效还取决于学员自主的程度和相应的远程教育的监控措施的不断完善。 远程教育未来的发展趋势为：（1）非盈利教育机构向盈利的商业机构方向发展；（2）逐渐成为构建知识经济时代人们终身学习体系的主要手段。尽管目前远程教育还存在着种种制约因素，但任何新生事物在其发展的过程中都是会遇到种种困难的，远程教育与传统学校教育相比有其无法替代的优势。我们都是社会中的一员，而现今社会正处于“知识爆炸”的时代，社会对我们的要求不断提高，因此我们需要时时“充电”——也就是时时学习，乃至终身学习。而正是远程教育为我们提供了这样的机会。因此我们应该合理开发利用。 我认为,一个真正有上进心的人,真正关注自身成长的人,没有任何理由不珍惜这次网上学习的机会。我觉得,在平时工作中,应该将远程教育与传统培训教育方式嫁接起来,这样学习效

中，选出一个进程为协调者 ?通过科学的分析制定一套规则? 。协调者对所有的请求进行排队并根据一定的规则授予许可。协调者接受请求以后，检查临界区内的资源是否被其他进程占用。如果是，则它将当前请求进程插入到对应临界资源的请求队列中 否则，回复一个同意消息给请求进程，通知它可以访问该临界资源。该算法通俗易懂，既能够杜绝死锁、饥饿等现象发生，又能保证资源的互斥访问顺利进行。 但是它也有缺点，由于是集中式管理，所以一旦管理进程出现故障，则整个系统将处于瘫痪状态。因此，管理进程的性能完全决定了算法的效率，应用范围小，难以普及。 分布式算法：分布式算法中运用到广播请求通信，当进程想请求共享资源时，需要首先建立三个变量 准备进入临界区，实时时间和处理器号，并利用广播通信发送给正在运行的所有进程。该算法的核心思想如下 当进程想进入临界区时 要建立一个包括进入的临界区名字、处理器号和当前时间的消息 并把消息发送给所有其它进程。当进程接收到另一个进程的请求消息时 将分下面三种情况来区别对待 ?若接收者不在临界区中 也不想进入临界区 就向发送者发送 ?消息； ?若接收者已经在临界区内就不必回答 而是负责对请求消息排队； ?若接收者要进入临界区 但还没进入 它就会把接收的消息和它发送的消息的时间戳进行对比 取小的那个。如果接收的消息时间戳小 就发 ?消息 如果发送的消息时间戳小 那么接收者负责排列请求队列而不发送任何消息。当进程接收到允许消息时 它就进入临界区。从临界区退出时 向队列中的所有进程发送 ?消息 并将自己从队列中删除。该算法可以保证访问临界区的互斥性以及无死锁进程、无饥饿进程。但是这种算法有个严重的缺点是算法太复杂并且不健壮 任何一个进程崩溃都会影响到算法的正确性。二是令牌丢失 令牌算法：令牌算法中引入了令牌，所有的进程组成一个环模型，环中每个进程需要知道它的下一个位置的节点的名称。令牌在环上顺序传递，当

远程教育的认识和理解

远程教育的认识和理解 一、什么是现代远程教育？ 远程教育经过函授教育、广播电视教育和现代远程教育三个历史阶段。现代远程教育是随着现代信息技术的发展而产生的一种新型教育方式。计算机技术、多媒体技术、通信技术的发展，特别是因特网(Internet)的迅猛发展，使远程教育的手段有了质的飞跃，成为高新技术条件下的远程教育。现代远程教育是以现代远程教育手段为主，容面授、函授和自学等教学形式，多种媒体优化、有机组合的教育方式。现代远程教育可以有效地发挥各种教育资源的优势，可以为各类教育提高教育质量提供有力支持，可以为各种社会成员学习提供方便的广泛的教育服务。 现代远程教育手段的主要特点是教师和学生能够跨越空间进行实时或非实时的交互。这也是现代远程教育与传统教育方式最显著的区别，也是它的优势所在。现代远程教育手段有以下优点：教师的讲授和学生的学习可以在不同地点同时进行，师生之间可以进行充分的交流；学生能够根据自已的需要自主安排学习时间和地点，自由选择学习内容，自行安排学习计划，随时提出学习中的问题并能及时地得到答解；现代远程教育手段有利于个体化学习。它以学生自学为主，充分发挥学生自主学习的主动性、积极性及创造性；现代远程教育手段可以为学生提供优质的教学服务。教师可以及时地了解学生的学习进度和对课程的理解程度，解答学生所提出的问题。现代远程教育给教与学的概念赋予了新的内涵，将给教育带来深刻的变革，推动教育观念、教育思想、教育模式和教学方法的更新。当然，现代远程教育手段并不是一种万能的教育方式，它不可能完全取代面授，也不一定适用于所有的教育层次和课程。它要求学生有较强的自学能力，并能够初步使用计算机。在目前技术手段的支持下，现代远程教育手段比较适合于知识的传授，对职业技能培训有很大的难度，现代远程教育手段更适宜于开展继续教育课程。利用计算机互联网络进行远程教育现已受到了许多国家和人们的关注，我国正在加紧建设和发展。 远程教育中的网络学校(教育)其实就是建立虚拟学校，是以学生为主体的自主学习环境；它是一种新型的、开放式的没有围墙的学校。它与传统广播电视教育的不同之处在于，人们可以在计算机网络的环境下，不受时间和空间的限制，完成“随时、随地的交互式”教学活动，使人们接受方便、高效的教育，教育质量得到明显提高。在工业经济时代，教育的模式是学生走进教室，而在信息经济时代，教育的模
