(2) 说一下汽车增多有什么好处或坏处。
(3) 你认为应该如何克服这些坏处？
More and more people own cars in the city. It's because the economy is expanding rapidly and therefore the family income goes up year by year. People want to enjoy a more comfortable life and earn certain social status.
There is no doubt that cars make us travel faster and farther, but they do have caused some problems. For example, they emit too much exhaust fumes and thus pollute the air. This causes further problems. The old people especially suffer a lot from it. Cars also contribute greatly to the increase of traffic jams and accidents.
How can we solve these problems? First, we can improve the qualities of the cars so that they produce less smokes and noises when running. Second, we should plant more trees and grass all over the cities to freshen the air. Lastly, we can build rings roads around cities so that they will less pollute the downtown areas.
V. Writing
Write a composition on the topic MY PLAN FOR THE FUTURE. Your composition should be based on the outline given below and you are required to write it in no less 120 words. Remember to write it clearly.
MY PLAN FOR THE FUTURE
(1) 你现在在做什么？
(2) 你对自己的将来有何打算？
(3) 你将如何去实现自己的计划？
I earnestly hope to lead a healthy and prosperous life in the future. Judging from my aptitude inclination and personality streaks, my ideal life will be that of a scientist, researching, lecturing, and writing books.
As I am from a farming family, I particularly enjoy being close to earth. If I can afford to live a pastoral life in the countryside, I will feel most blessed. As far as social life is concerned, simplicity is what I intend to pursue, so I really don't need too many friends. All these will be mere talk if I am idle now. To attain my goal, I must make a point of training my body and mind. This is a highly competitive society in which everyone is eager to come out on top. That is not only a competition of physical strength and mental power, but a marathon of patience, faith, and perseverance. Life is not all roses, but with what I am being equipped with by the top teachers in this elite school, I surely deserve a promising prospect.
计算机网络答案-山东大学期末考题目答案
第一章概述 1-3试从多个方面比较电路交换、报文交换和分组交换的主要优缺点。 答：1、电路交换电路交换是一种必须经过“建立连接-通话-释放链接”三个步骤的一条专用物理通路。从建立连接开始，通讯就一直占用信道资源，直到释放。它具有实施性强，时延小，交换设备成本低的优点。同时，其线路利用效率低，通信效率低，不同类型终端之间不可通讯。电路交换适用于信息量大，较长的报文。 2、报文交换报文交换本质上也是存储转发方式，但是它将整个报文从一个结点传到下一个。它的优点是中继电路利用率高，可以多个用户同时在一条线路上传送。缺点在于报文信息量大，时延长，且占用交换机内存较大，不具有实时性。它适用于报文较短，实时性较低的通讯。 3、分组交换分组交换是将报文分组，在每个分组之前加上地址信息，通过路由器经接收，存储，再转发到下一个接口，直到将分组传到目标地址，再去掉地址信息将其重组为完整报文。在分组传输的过程中动态分配传输宽带，逐
段占用通信链路，多个分组数可同时传送。它传输效率高，且保证数据传输有很高可靠性。同时分组排队会造成时延，但比报文交换小，且成本较高。 1-12 因特网的两大组成部分（边缘部分与核心部分）的特点是什么？他们的工作方式各有什么特点？ 答：边缘部分由所有连接在因特网上的主机组成，由用户直接使用，进行通信和资源共享。核心部分，是由大量网络和连接这些网络的路由器组成，主要为边缘部分服务提供连通性和交换。边缘部分不同终端上的程序通信方式有客户-服务器方式和对等方式。客户-服务器方式指进行通讯的双方中一方为服务请求方，一方为服务提供方。客户向服务器发送远程服务请求，因此客户程序必须知道服务器程序地址，而服务器只需要被动接受请求，不需要知道客户程序地址，但需要强大硬件和高级操作系统支持。对等方式是双方均可既为服务提供者，也可以为服务请求
第2单元 2013年大学网络学习新闻英语二，网上虽然有些答案但是不大一样，也没有听力原文，这里的最全 准备 1.Exercise 1: Listen to this passage and decide whether the following statements are true or false, write T for true and F for false. 听力文本： Airport Security Screens Passengers Using New Technology Checking baggage for explosives hasn't been a problem. Airport security can put bags in x-ray machines, open them up to look inside, or use advanced machinery that that check traces of chemicals often used in explosives. But checking people's bodies isn't so easy. A TSA initiative that began last September to rigorously frisk more people led to dozens of sexual harassment complaints. So the TSA turned to technology installing what looks like a longer, more complex walk-through metal detectors in nine airports around the country. Jose Ralls is the TSA director from McCarran International in Las Vegas. Jose Ralls: The machine actually will talk to the individual, telling them to stand inside and wait, and as soon as they are cleared, it will tell them to proceed. From a distance, Mr. Ralls watches one airport passenger go

第七章新闻图片编辑 【知识框架】 【重点难点归纳】 一、新闻图片的种类及其地位 1．报纸上常见的图片种类 (1)照片 新闻照片就是以新闻事件、新闻人物为拍摄对象，再现新闻现场情景的照片，它可以作为独立的新闻报道出现在版面上，也可以配合文字报道一同编发。 (2)漫画 漫画在现代报纸上的使用非常广泛，有根据新闻事实进行艺术加工的新闻漫画，时效性较强，经常刊登在新闻版上；也有反映社会生活现象的社会性漫画，通常刊登在专刊副刊上；还有用来配合文字报道的图解式漫画以及连环漫画、幽默画等。 (3)图示 图示包括统计图表、示意图和新闻地图三类。 统计图表就是将统计数字制成表格图，便于读者集中阅读，一目了然。
示意图不但将统计数字集中绘制成图，而且用形象化的手法表示这些数据所说明的意义。 新闻地图则是根据标准地图，将新闻发生地的地理位置绘制成更加简洁明确的地图。 (4)图饰 图饰一般是用美术图案点缀和烘托报纸的报头、报眉、标题、栏题、版头或版面的其他部位，使整个版面更加美观生动，恰当地运用图饰还能使版面编排思想得到更加充分的体现。 2．图片的地位与作用 (1)纪实性作用 作为独立报道体裁的新闻照片具有再现新闻现场、记载真实瞬间的作用，这类照片成为报纸上不可或缺的重要组成部分。 (2)证实性作用 非独立使用的新闻照片与非新闻照片具有证实文字报道的作用，这类照片对新闻资源的充分发掘，对提高新闻报道的可信度具有重要意义。 (3)解说性作用 图表、示意图、新闻地图、漫画等能够以形象性的符号统计和描绘新闻报道中的某些内容，从而对相对比较枯燥的文字表述进行生动易懂的解释。 (4)装饰性作用 图片的形象性特征使其可以作为文字稿件的美化装饰手段。 (5)视觉冲击性作用 图片的形象性和直观性能够产生强烈的视觉冲击效果，产生巨大的吸引力与震撼力，这是文字报道所难以达到的。
