A.hardly;high B.hard;high C.hardly;highly D.hard;highly 答案B[有些考生可能会认为动词后面应用副词修饰,而形容词后面加-ly就成副词了,于是错选A、C或D。其实,hard和high都既可作形容词,也可作副词。hard作形容词时意为“坚硬的;难懂的”,作副词时,意为“努力地;猛烈地”;而hardly是副词,意为“几乎不”;high作形容词时,意为“高的,有……高度的”,作副词时意为“在高处,向高处”; 而highly是副词,意为“高度地”,表示抽象意义。根据句子语境可知,正确答案为B。] 2.The case is being looked into;a team consisting of top Chinese police officers will leave for Japan soon to ________the truth. A.uncover B.recover C.indicate D.represent 答案A[句意:这个案子正在调查中,由中国高级警官组成的调查团很快将赴日本揭开事实真相。uncover“揭露”;recover“恢复”;indicate“指示”;represent“代表,象征”。故选A项。] 3.By the time my friend gets to Australia next Sunday,I________for America. A.will have left B.might have left C.will leave D.am leaving 答案A [考查动词的时态。句意:当我的朋友下周日到达澳大利亚时,我也已经离开去了美国。by the time用作连词,引导时间状语从句,意为“到……时候”,当它引导的从句的时态用一般现在时时,主句的时态通常用将来完成时。此处指到下周日“我”将已经去了美国,故用将来完成时。] 4.________money is concerned,I always try to be very careful. A.Where B.When C.Why D.How 答案A[句意:凡是涉及钱的地方,我总是尽量小心谨慎。where...is concerned=as far as...is concerned“就……而言”。] 5.—Why did you refuse to move into the office? —Because it was really in a poor ________and dirty.

A.therefore B.although C.since D.unless 答案B [考查状语从句。句意:尽管我必须说你的确看起来面熟,但我认为我们没见过面。此处为让步状语从句,故用although引导。] 2.After five hours on your feet,you ________a break. A.conserve B.deserve C.observe D.reserve 答案B[conserve保存;deserve值得;应该;observe观察;遵守;reserve 保留。由句意“站了五个小时后,你应该休息一下。”可知,B项正确。] 3.The reason________he told me________he was late is an excuse. A.why;that B.that;why C.which;that D.that;which 答案B [解析:句意:他告诉我的为什么他会迟到的原因完全是个借口。本句的主干是:the reason is an excuse。其中的he told me是定语从句,省略了在定语从句中作宾语的引导词which或that;其中的he was late也是定语从句,也修饰先行词the reason。引导词可以用that,for which,why或者不填,在定语从句中作原因状语。] 4.—I have heard that John wrote a long letter to the president. —His uncle insisted that he ________it. A.did B.had done C.do D.would do 答案C[句中的insist意为“坚持要求”之意,因此宾语从句应用虚拟语气 形式,故C为正确答案。] 5.The growing speed of a plant is influenced by a number of factors,________are beyond our control. A.most of them B.most of which C.most of what D.most of that 答案B[句意:植物的生长速度受诸多因素的影响,绝大多数的因素是我 们控制不了的。which引导非限制性定语从句,且作介词of的宾语。] 6.Last week,only two people came to look at the house,________wanted to buy it. A.none of them B.both of them

2015创新设计-网络技术(第2章)

14 第二章 数据通信基础 【高考考纲】 高考考纲 考情分析 1.掌握数据通信的基本概念。 2.掌握数据传输方式及数据交换技术。 本章是计算机网络技术的重要章节。本章概念较多要注意概念间的分类和区别,考点以选择题和简答题的考查为主。 第一节 数据通信的基本概念 考点一:信息和数据 【知识梳理】 1.信息 ①信息是对客观事物的反映,可以是对物质的形态、大小、结构、性能等全部或部分特性的描述,也可表示物质与外部的联系。 ②信息有各种存在形式,例如数字、文字、声音、图形和图像等。 2.数据 ①信息可以用数字的形式来表示,数字化的信息称为数据。 ②数据是信息的载体,信息则是数据的内在含义或解释。 ③数据可以分成两类:模拟数据和数字数据。计算机中的信息都是用数字形式来表示的。 助记图: 【典例精讲】 例1.计算机中存储的是()数据 A .数字 B.模拟 C.数字或模拟 D.以上都不对 【解析】数据可以分成两类:模拟数据和数字数据。计算机中的信息都是用数字形式来表示 内在含义 载 体 数字化信息 信息 多种形式 数字 文字、声音、图形和图像 数据

的。 【答案】A 【跟踪练习】 1.下列关于信息和数据的说法不正确的是() A.信息是对客观事物的反映 B.数据是信息的载体 C.数据是信息的一种存在形式 D.信息是数字的内在含义 答案:C 考点二:信道和信道容量 【知识梳理】 1.信道 ①信道是传送信号的一条通道,可以分为物理信道和逻辑信道。 ②物理信道是指用来传送信号或数据的物理通路,由传输介质及其附属设备组成。 ③逻辑信道也是指传输信息的一条通路,但在信号的收、发节点之间并不一定存在与之对应的物理传输介质,而是在物理信道基础上,由节点设备内部的连接来实现。 2.信道的分类 ①信道按使用权限可分为专业信道和共用信道。 ②信道按传输介质可分为有线信道、无线信道和卫星信道。 ③信道按传输信号的种类可分为模拟信道和数字信道。 3.信道容量 ①概念:信道容量是指信道传输信息的最大能力,通常用信息速率来表示。 ②信道容量大,单位时间内传送的比特数越大,则信息的传输能力也就越大,表示。 ③信道容量由信道的频带(带宽)、可使用的时间及能通过的信号功率和噪声功率决定。 ④信道容量的表达式:C =Blog(1+S/N) C:信道容量 B:信道带宽 S:接收端信号的平均功率 N:信道内噪声平均功率 【典例精讲】 例2.关于信道下列说法不正确的是() A.信道是传送信号的一条通道 15
