备考托业（TOEIC）需要用到的教材及备考资料推荐（备考必看经验分享）本文针对“托业备考用什么资料有用”进行详细的说明。

第一，暑假回国的学生很多，其中打算备考的不在少数。

苦于参考书市场琳琅满目，实在不知从何下手。

希望本文能作为托业相关书籍的导购建议，让读者在备考中少花钱，少走弯路；其次，我自己短暂的备考也用过一些书，所以一定要能尽量客观的评价备考资料。

为了节省时间，以下参考资料将按推荐度排序(从高到低)。

NO.1公号（全网知识加油站）的托业系统课推荐指数：★★★★★推荐理由:我觉得自己不是一个自律的人，也没有什么超强的学习能力，所以上网络课程无疑成为了最好的选择。

几经周折，看了很多分享帖，终于在公众号找到了。

我觉得在开始之前先跟着系统课刷一遍基础知识点是很有必要的，不仅可以帮助我们对考试有一个很详细全面的了解，而且可以帮我们巩固基础，提升英语能力，最主要的是在里面我们可以学习到应试技巧，毕竟面对应试教育，我们还是要有选择的来进行备考。

（ps: 他家的网课真真实实是穷学生的避风港）Plus:网课一定要刷一遍，毕竟你后期刷题是需要基础和对试题的基础认知的，并且课程里有全面的题型讲解，不服不行！NO.2第一本书《新托业全真题库》（2018年托业最新题型）推荐指数：★★★★★自学指数：★★★PK真题难度：偏难（意思是比真托业考试难度大了一些）推荐理由：韩国人编辑托业真题的又一力作！国内2018年首销。

这本书刚下印刷厂流水线，我就下单买了。

果然！不出所料，我最想要的真题，里面竟然印了5套，每套题后面也有粗略的中文解释。

但是，解释的时候语法名词使用过多，过繁，对一些个自学托业但是语法名词基础不好的“直觉型”考生不是很友好。

NO.3 Youtube 音视颇推荐指数：★★★★自学指数：★★★★★PK真题难度：一样（不排除个别套题略难）推荐理由：（自学资源的乌托邦）Youtube：作为世界最大的学习视频类网站，上面的教程种类繁多，应有尽有。

结晶果糖结晶果糖具有高甜度的特点，它的甜度是蔗糖的1.3～1.8倍。

同时，具有风味强化、甜味强化、高保湿性、低水活性、可强化Maill ard反应、高渗透压、降低凝冻温度、快速／强化成胶等功能特性。

由于研究的不断深入，使其应用领域愈加宽广。

果糖在水果罐头、果冻、果酱、调味品和糖果等产品中对提高质量、降低热量和成本以及新产品开发都有很大帮助。

结晶果糖为单糖，是糖类中化学活性最高的糖，天然存在于蜂蜜及菊芋、菊苣等菊科植物中。

果糖甜度高，有水果香味，热值低，在体内代谢比葡萄糖快，易被机体吸收利用，且不依赖胰岛素，对血糖影响小，适用于葡萄糖代谢及肝功能不全的患者补充能量。

在人体内能促进有益细菌如双歧杆菌类生长繁殖，抑制有害菌生长，改善人肠胃功能和代谢，降低血脂，不致龋齿，是糖尿病人、肥胖病人、儿童食品的理想甜味剂。

果糖甜度高、热能低，健康饮品常使用果糖来降低甜味剂的固形物的含量。

果糖与其他甜味剂如葡萄糖、蔗糖以及阿斯巴甜混合使用具有甜味强化的效果，从而能够降低甜味的材料成本。

试验表明，将果糖与蔗糖以1∶1比例混合添加在饮料中，可比单纯用蔗糖减少20％的甜味剂用量结晶果糖是一种高档食品糖料，是一种天然健康糖，结晶果糖是一种单糖、吸收快、不会引起血糖升高、不至龋齿、是一种新的健康食糖，代蔗糖放面效果好摘要:纯果糖虽是一种天然营养甜味剂，但过去难以应用于各种食品配方中，原因是价格昂贵。

但随着工业化生产，纯结晶果糖在欧美、日本等发达国家已用于功能食品、营养保健食品、冷饮食品以及低热值食品和运动型饮料配方中。

随着纯结晶果糖逐渐在我国进入工业化规模生产，可以预计这种天然营养甜味剂在食品中的应用也将会越来越多。

山东西王生化科技有限公司是国内最早研发结晶果糖的上市公司、也是亚洲最大的结晶果糖生产企业。

结晶果糖英文名：Fructose分子式：C6H12O6分子量：180.16性状：吸湿性极强的白色无臭结晶或结晶性粉末。

味甜，舔度约为蔗糖的1.6倍，为糖类中最甜者。

SAN是千兆位速率的网络，它依托光纤通道(Fibre Channel)为服务器和存储设备之间的连接提供更高的吞吐能力、支持更远的距离和更可靠的连通。

SAN可以是交换式网络，也可以是共享式网络。

以目前的技术，其中任何一种网络都能够提供更好的伸缩性、故障恢复和诊断信息;此外，以其中任何一种网络为基础建设SAN都不需要对现有设施进行全面升级。

由于降低了管理成本，SAN的基本设施的最初成本也就变得并不昂贵。

SAN的组成通常包括服务器(主机)、存储设备(磁带或者磁盘阵列)以及桥接器和多路复用器，并且所有这些设备都连接在光纤通道的交换机上。

在LAN和W AN环境中，交换机为连接着的所有设备提供主干，其中的一个或多个交换机称为光纤通道交换矩阵(Switching Fabric)。

SAN的交换矩阵允许数以千计的结点进行连接。

SAN还可以组成FC-AL环网(Fibre Channel Arbitrated Loop)，这是一种共享介质的网络。

FC-AL环网结构在每个环上允许多达126个设备，可以直接连接到光纤通道的交换机上，也可以连接到和交换机相连的集线器上。

此外，光纤通道还有助于分担服务器的负载，以前服务器一直要承担向存储设备和LAN传输数据的负担;而现在，服务器可以将传输数据的工作交给SAN。

SAN的设计要进行SAN网络的安装，任务是相当简单的。

光纤通道SAN可以设计成共享介质的网络，也可以设计成交换式访问的网络。

在共享介质的网络中，所有设备共享同一个千兆位的环，这种结构的问题在于随着设备的增加，网络的吞吐能力会下降。

尽管对于小型应用环境来说这也许是可以接受的，但基于光纤通道交换机的主干将大大增加SAN的总带宽。

建立交换矩阵SAN可以使用一个或多个光纤通道交换机，然而只有当所有存储设备的网卡象操作系统和应用一样能够连接到这一交换矩阵上，才有可能访问由这一交换矩阵所提供的服务。

这是因为首先网卡要通过登录到这一交换矩阵来成为网络的一个成员，这一过程称作Fabric Login。

第1章1、通信：是指不在同一地点的双方或多方之间进行迅速有效的信息传递。

单工半双工全双工串行传输：传输慢、但传输距离远。

并行传输：传输快、但传输距离近。

两点间直通传输、分支传输和交换传输3、信号：是信息的一种电磁编码。

信号是信息的载体。

通信系统的基本模弄4、通信系统的主要性能指示有效性：是指信息传输的效率。

可靠性：是系统接收信息的准确度。

备注：衡量系统有效性最全面的指标是系统的频带利用率。

第二章一、调制的分类：1、根据调制信号分类：模拟调制和数字调制2、根据载波分类：连续载波调制和脉冲载波调制3、根据调制的功能分类：AM、FM、PM4、根据调制前后的频谱关系分类：线性调制和非线性调制5、线性调制分为：AM、DSB、SSB、VSB6、单边带调制方法有：滤波法、移相法、移相滤波法备注：常规双边带调制（AM）调制效率最低，而单边带调（SSB）制效率最高解调的方法：相干解调（同步检波）和非相干解调（包络检波）。

7、频率调制分为：划分依据是瞬时相位偏移是否小于0.5窄带调制（NBFM）宽带调制（WBFM）8、调频分为：直接调频和间接调频间接调频：是选积分，然后再调相 如下图：第3章1、PCM （脉冲编码调制）包括三个部分：抽样、量化、编码。

2、数字信息的电脉冲表过程称码型变换。

应该考虑的问题：低频和高频频率分量应尽量少，特别是不能含有直流分量； 不能有长连0和1码，以便提取同步定时信息；具有自检自纠能力。

3、二元码的极性图P534、抽样定理分为：自然抽样和平顶抽样（性能比自然抽样性能好）5、量化分为：均匀量化和非均匀量化备注：只要确定了量化器，则无论抽样值大小如何，其量化噪声的平均功率值都是固定不变的；因为，X （T ）较小时，输出信噪比就很低，弱信号的量化信噪比就可能无法达到额定要求而对还原解调产生较大的影响。

6、非均匀量化分为：A 率13折线（中国使用）和U 率15折线。

A=87.6 U=2557、编码：自然二进制码组、折叠二进制码组、格雷二进制码组。
