Friendship
Have You Made Any Friends Online?
Friendship in our hearts is forever pure, fresh and simple. I often feel very lucky to have a lot of good friends. Justin was my English teacher from the U.S.A.. I met him when I was a student. He was a vivid young man with a bright smile on his face, and he always had a special way to make the class active. He taught us English by telling stories, playing games, singing songs, and even dancing. I could still remember very clearly that one afternoon when we finished our class, we went to some other classes to sing songs for them, just like people did in the States on Christmas Eve. It was so interesting and unforgettable. Justin was an excellent teacher, because he taught us not only the way to study English well, but also the way to find the beauty in the world. Justin is my best friend, and I will cherish those days spent with him as the best part of my memory.

Shift registers
A register capable of shifting its binary information in one or both directions is called a shift register.
The simplest possible shift register is one that uses only flip-flops.
The output of a given flip-flop is connected to the D input of the flip-flop at its right. The clock is common to all flip-flops. The serial input determines what goes into the leftmost position during the shift. The serial output is taken from the output of the rightmost flip-flop.

参考译文
寄存器是一种特殊的内存，它存在于处理器内。通常一 个处理器带有几个比主存快得多的内部寄存器。这些寄 存器常常具有算术、逻辑或其他运算的特殊性能。寄存 器一般相当小。一些寄存器分为整数寄存器和地址寄存 器，而其他一些寄存器是通用寄存器，既可以用于存储 数据也可以用于存储地址。一个处理器通常有1到32个数 据或通用寄存器（带有分开的数据寄存器和地址寄存器 的处理器通常平分寄存器组）。许多处理器有特殊的浮 点寄存器（并且某些处理器有既可以用于整数也可用于 浮点运算的通用寄存器）。
参考译文
2.5 外部存储器 外部存储器（也叫做“辅助存储器”）是主存之外的任 何一种存储器。在现代，这主要指硬盘和可移动介质。 随着USB和火线硬盘的到来，持久式硬盘与可移动介质 之间的界限已经模糊了。随机访问或索引访问设备提供 了对内存的扩展（虽然通常通过逻辑文件系统访问）。 顺序访问设备提供了大量信息的离线存储（数据备份）， 通常被称为I/O（输入/输出）设备。
Phrases
game controllers in charge of in order input device instruction sets integrated circuit magnetic core main storage output device 游戏操纵杆 负责 按照顺序 输入设备 指令集，指令系统 集成电路 磁芯 主存 输出设备
参考译文
ROM是只读存储器（它也是随机访问的，但只能读）。 ROM通常用来存储计算机一生不变的东西，如操作系统 的低级部分。一些处理器（或处理器家族中的变种）可 能有内置在处理器同一芯片中的.RAM和/或ROM（通常 用于独立设备的处理器，如ATM、微波炉、汽车发动系 统等）。 EPROM是可擦可编程只读存储器，是一种特殊的ROM， 可以用特殊设备（但不是用与它相连的处理器）擦除和 重新编程。EPROM允许工业设备（及其他类似设备）的 制造者获得ROM的益处，同样也考虑到软件更新或升级， 而无须再购买新的ROM并把老的扔掉。

1.2 Software Development Process
• Complex Sentences
– 1. Original: Software training and support is important because a large percentage of software projects fail because the developers fail to realize that it doesn’t matter how much time and planning a development team puts into creating software if nobody in an organization ends up using it. – Translation:软件培训和支持很重要，这是因为大多数软件项目的 失败是由于开发者没有认识到：如果机构中没有人最终使用它， 那么开发团队无论投入多少时间和计划到开发软件中都无济于事。

发展智慧城市技术的领域包括政府服务、运输和交通管理、能源、保健、水、创新的城 市农业和废物管理。
主要技术、经济和环境变化已经引起了人们对智慧城市的兴趣，这些变化包括气候变化、 经济重组、网络零售和娱乐，城市人口增长和公共财政压力。欧盟（EU）一直致力于增加 其大都市圈实现“智能”的城市增长策略。欧盟根据“欧洲数字议程”制定了一系列计划。 2010 年，它强调其重点是加强 ICT 服务的创新和投资，以改善公共服务和生活质量。据 Arup 估计，到 2020 年用于智慧城市服务的全球市场将达到每年 4000 亿美元。
