Unit9 知识要点1.1. Hmm, depends which movie.=It depends (on) we`ll watch which movie.1) 本句省略了depends前的主语it和which movie后的从句部分we’ll watch，在口语和非正式场合，保持语言简洁明了，交流者往往省略彼此所知或逻辑上可明确推断的内容。
如：1. Anything I can do for you? 我能为您做些什么吗？（省略句首部分Is there）2. Please hand me one of those books. I don’t care which. 请把那些书递给我一本，不管哪本都行。
（省略句尾部分you hand me）2) It depends (on) who/ what/ how/ whether…是一个常见句型。
当depend后接疑问词及含疑问词的短语和从句时，口语中会省略depend后的介词on，以求话语简练。
例如：1.那的看谁来做这个报告。
.2. I can’t decide for now.（这得取决于你老爸是否会同意。
）2. I just want to laugh and not think too much.这句话中的to laugh和not think too much均为动词不定式，但后者在not和think之间省略了to。
英语语句中当多个不定式结构并列使用时，to出现在第一个结构中，后面的往往会省略。
再如：She likes .her friends. 她喜欢唱歌、跳舞、与朋友们外出消遣。
3. I prefer music that has great lyrics. prefer意为“更喜爱；更喜欢”，后接名词、v.-ing形式或动词不定式。

Originally the aim was to allow the exchange of information (programs, data files) between the users of different mainframes. When smaller computers became available and spread in large numbers within a single organization, connections between these small computers became attractive for the shared use of resources as well. The resulting systems, in which computers of possibly different type and size are connected but fully retain their autonomy, are called computer networks. Computer networks, world-wide networks of (large) computers are referred to as wide area networks (WAN) and campus-wide networks of (small) computers are referred to as local area networks (LAN).Originally dv. 原本, 起初, 独创地1. retain vt.保持, 保留Her memory retains everything she reads. 她过目不忘。
2. autonomy [ɔ:ˈtɔnəmi] n.自治, 自治权, 自主[计算机]1.独立性，自主性，自治性20世纪60年代，在计算机广泛使用的同时，人们便期望将其连接在一起。
最初的目的是为了能够在不同主机的用户间交换诸如程序与数据文件之类的信息。
当小型计算机被使用并大量存在于独立机构内部时，为了共享资源，小型计算机间相互连接变得更有意义。
由此形成的系统被称为计算机网络，其中计算机的类型与尺寸可能不同，它们相互连接但完全保持独立。
计算机网络中，全球范围的大型计算机网络称为广域网，校园范围内小型计算机网络称为局域网。
To reduce the design complexity, network architecture is viewed as a series of layer or levels. Each layer (or level) consists of protocols that use functions of lower layers and provide services to the higher layers. Each layer performs well-defined functions, and can be of limited complexity. Together the layers implement the facilities of the network.3. complexity n.复杂(性), 复杂的事物, 复杂性We are facing a problem of great complexity. 我们正面对着一个极复杂的问题。
