Text History of Water Supply

[1] Man’s search for pure water began in prehistoric times.

人类在史前时期就开始寻求洁净的水。

Much of his earliest activity is subject to speculation. 人类最早的许多活动是不难推测的。

Some individuals might have led water where they wanted it through trenches dug in the earth. 一些人可能在地上挖沟，把水引到所需要的地方。 Later, a hollow log was perhaps used as the first water pipe. 后来，空心圆木可能

Section 2 The Reliability of a Survey and Errors

测量误差的可靠性

Since every technique of measurement is subject to unavoidable error, surveyors must be aware of all sources and types of error and how they combine. If the accuracy of a measurement is defined as the nearness of that value to its true value (a quantity we can never know) then a surveyor must ensure that the techniques he chooses will produce a result that is sufficiently accurate. He must know, therefore, how accurate he needs to be, how to achieve this accuracy and

A部分 Windows 7

1. 简介

Windows 7是微软最新发布的windows版本,这一系列微软制造的操作系统主要用于个人电脑,其中包括家庭和商业台式电脑、笔记本电脑、上网本、平板电脑、和媒体中心电脑。(见图4.1)Windows 7于 2009年7月22日开始生产,并在 2009年10月22日零售,这个时间距其推出其前任Windows Vista不到三年时间。与Windows 7相对应的Windows server 2008 R2,也是同年发布。

不像其前一操作系统vista，windows7 引入了大量的新特性，更集中于增量升级的windows线，目标是兼容已经在vista中兼容的应用程序和硬件。微软在2008年的报告中关注于对于多点触控的支持，以及一个重新设计的windows shell和一个新的任务栏，并将其称之为Superbar，还有一个称之为家庭组的网络系统，注重性能改进。之前版本的windows系统中的一些标准的应用程序，包括windows日历，windows邮件，windows movie maker，和windows相片画廊在windows 7中并没有包含进来，而大多数是作为

UNIT 1 What are Polymer?

第一单元 什么是高聚物？

What are polymers? For one thing, they are complex and giant molecules and

are different from low molecular weight compounds like, say, common salt. To contrast the difference, the molecular weight of common salt is only 58.5, while that of a polymer can be as high as several hundred thousand, even more than thousand thousands. These big molecules or ‘macro-molecules’ are made up of much smaller molecules, can be of one or more chemical compounds. To illustrate, imagine tha
