given environment?

micro-environment has more impact on day-to-day operations?

a. Because understanding trends in PESTEL factors enables an organisation to

anticipate changes, threats and opportunities arising in the operating

environment.

of the organisation. That is why they are called PESTEL factors.

by PESTEL factors.

analysis and you would have an incomplete analysis otherwise.

荆楚培优题第1讲全等三角形1-2(word版)

荆楚培优题第1讲全等三角形1-2(word版)

荆楚潮2015年八年级秋季培优讲义 全等三角形（一）

一、知识要点

全等三角形是平面几何内容的基础，这是因为全等三角形是研究特殊三角形、四边形等图形性质的有力工具，是解决与线段、角相关问题的一个出发点，运用全等三角形，可以证明线段相等、线段和差倍分、角相等、两直线位置关系等常见的几何问题.

利用全等三角形证明问题，关键在于从复杂图形中找到一对基础的三角形，这对基础的三角形从实质上来说，是由三角形全等判定定理中的一对三角形变换而来，也可能是由几对三角形组成，期间的关系互相传递，应熟悉涉及公共边、公共角的基本图形.

（1）全等三角形的概念及其性质，注意：平移、翻折、旋转前后的两个图形全等；

（2）全等三角形的判定方法：SSS、SAS、ASA、AAS、HL，注意：SSA、AAA全等

二、基础能力测试：

1．全等三角形是两个能够______的图形，全等图形的____和_____都相同.

2．如图，把△ABC沿着直线BC为轴翻转180°后变到△DBC的位置，那么△ABC与△DBC____

全等图形（填“是”或“不是”）；若△ABC的面积是3，则△DBC的面积为_______.

3．如图，在Rt△ABC中，∠ABC=90°，AB=3，AC=5，点E在BC上，将△ABC沿AE折叠，使点B落在AC边上的点处，则BE的长为_________.

4．如图，已知△ABC≌△DEF，且AB=4，BC=5，AC=6，则DF的长为_______.

5．如图，在△ABC中，点D、E分别是边AC、BC上的点，若△ADB≌△EDC，则∠C的度数为________.

6．如图，△ABC≌△ADE，BC的延长线交DA于点F，交DE于点G，已知∠ACB=∠AED=105°，∠B=∠D=25°，求∠DFB和∠DGB的度数.

ABCDABCDEABCB'EABCDEFABCDEG【例1】已知如图，点B、E、C、F在同一条直线上，AB=DE，AC=DF，BE=CF.

Chapter 2 Phonology 音系学

1. The phonic medium of language 语言的声音媒介

Linguists are not interested in all sounds ；they are concerned with

only those sounds that are produced by the human speech organs in so far

as they have a role to play in linguistic communication .These sounds are

limited in number .This limited range of sounds which are meaningful in

human communication and are of interest to linguistic studies are the

phonic medium of language ;and the individual sounds within this range

are the speech sounds.

语言学家也并不是对所有的声音感兴趣，他们只关注那些在语言交际中占有一席之地、由人类的发音器官所发出来的那些声音.这些声音在数量上是有限的。这些范围有限,但对人类交际活动意义重大、对语言学研究价值不菲的声音就是语言的声音媒介，凡是在这个范围的每个单个的声音都叫做语音。

2. Phonetics 语音学

2.1 What is phonetics？ 什么是语音学？

Phonetics is defined as the study of

the phonic medium of language;

1.2 Chapter 2 Pollution Fighters 教案(牛津上海版八年级下册)

Chapter Two Pollution Fighters

I. 章节分析

（一）综述

本单元的Reading部分的文章是关于“树和环境”。通过一名中学生采访科学家来了解“树”对环境保护所起的作用。“污染”问题是一个旧话题，在6B Module 1The Natural Elements和教材后面的Project 1 The Environment 都谈论到环境与污染的问题；7A Module 3 Natural

Elements Unit 4 Forests and land中谈到了森林，实际上就是谈树的作用和用途。其中的大部分内容都是我们的学生很熟悉的，所以老师在引入新课时，可以从学生们熟悉的话题“森林”谈起，很自然的进入新课内容。

本单元的Listening部分也是围绕主题，通过Completing a notice的形式，进一步让学生了解树的作用，从而积极投入到“植树战役”中去。Language部分介绍了现在进行时(the

present continuous tense)的用法。Speaking部分围绕本课的主题讨论How to fight pollution?

我们可以把这部分内容放在Post-reading环节，让学生进行讨论。Using English部分 (The

index) 老师可以告诉学生the index 与the contents page 都可以帮助我们快速了解一本书的信息，只是the index 的排版大部分在书后，而且是以字母循序排列的，有主题，比较详细而the contents page 的排版在书的前面，按页码排序。Writing部分是为学校报纸写一篇有关工人们是如何建造一个sitting-out area的文章。

（二）教学目标

1. 知识目标

1）词汇：掌握本章出现的生词。

2）语法：能熟练运用现在进行时的陈述句，一般疑问句，特殊疑问句。

3）功能：能和同学，老师表达自己的思想。

1.2.1函数的概念

活动1

问题1． 请同学阅读课本1516PP的三个实例，并完成后面的问题：

①一枚炮弹发射后，经过26 s落到地面击中目标．炮弹的射高为845 m，且炮弹距地面的高度为h(单位:m)随时间t(单位:s)变化的规律是h=130t-5t2．时间t的变化范围是数集A={t|0≤t≤26}，h的变化范围是数集B={h|0≤h≤845}．

②近几十年来，大气层的臭氧迅速减少，因而出现了臭氧洞问题．图1-2-1-1中的曲线显示了南极上空臭氧层空洞的面积S(单位:106 km2)随时间t(单位:年)从1991~2001年的变化情况．

图1-2-1-1

根据图1-2-1-1中的曲线，可知时间t的变化范围是数集A={t|1979≤t≤2001}，空臭氧层空洞面积S的变化范围是数集B={S|0≤S≤26}．

③国际上常用恩格尔系数反映一个国家人民生活质量的高低，恩格尔系数越低，生活质量越高．下表中的恩格尔系数y随时间t(年)变化的情况表明，“八五”计划以来，我国城镇居民的生活质量发生了显著变化．

“八五”计划以来我国城镇居民恩格尔系数变化情况

时间 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000
