No one can believe that the Great Wall might disappear some day. Believe it or
not, the Great Wall is being destroyed by people. Less than 20 percent of the Great
Wall built in the Ming Dynasty is still perfect, but about 80 percent is in danger.
The Great Wall can be called “great” mostly because of its amazing length. But we
should realize that the length was made up of one brick at a time. If we do nothing
to save the Great Wall, it will become a series of separate wasteland rather than
a historic site.
The Great Wall is actually a series of walls built and rebuilt by different
dynasties over the past 2,000 years. It began in the rule of China's first emperor,
Qin Shihuang of the Qin Dynasty, and lasted into the Ming Dynasty. The parts built

勒斯的传
统披萨饼榜上有名，想知道它的故事吗，一起来听听吧……Pizza is favored by lots of people. It's great to share it with friends, to bring it to a party，
or just to enjoy it by yourself. Recently, pizza twirling① has even received recognition from UNESCO asa cultural heritage.Pizza has been a part of Italian culture for centuries. In the 1700s and the 1800s, the city of Naples (那不勒斯) in Italy was an independent kingdom, known for its large
working class. Pizza began as a poor man's food—as a way to feed people in poverty②
quickly and at a low cost③. Flatbread with different kinds of toppings such as cheese, tomatoes, anchovies, oil, and garlic was considered street food and looked down upon by wealthy Italians.
In 1889, King Umberto Ⅰ and Queen Margherita visited Naples, which had by then come under a unified Italy. On their visit, the royal couple enjoyed pizza from a local eatery. The queen's favorite turned out to be pizza topped with cheese, tomato, and basil—it is no surprise that it came to be known as Pizza Margherita!

§11．1 全等三角形
教学目标
1．知道什么是全等形、全等三角形及全等三角形的对应元素；
2．知道全等三角形的性质，能用符号正确地表示两个三角形全等；
3．能熟练找出两个全等三角形的对应角、对应边．
教学重点
全等三角形的性质．
教学难点
找全等三角形的对应边、对应角．
教学过程
Ⅰ．提出问题，创设情境
1、问题：你能发现这两个三角形有什么美妙的关系吗？
C1B1CABA1
这两个三角形是完全重合的．
2．学生自己动手（同桌两名同学配合）
取一张纸，将自己事先准备好的三角板按在纸上，画下图形，照图形裁下来，纸样与三角板形状、大小完全一样．
3．获取概念
让学生用自己的语言叙述：全等形、全等三角形、对应顶点、对应角、对应边，以及有关的数学符号．
形状与大小都完全相同的两个图形就是全等形．
要是把两个图形放在一起，能够完全重合，•就可以说明这两个图形的形状、大小相同．
概括全等形的准确定义：能够完全重合的两个图形叫做全等形．请同学们类推得出全等三角形的概念，并理解对应顶点、对应角、对应边的含义．仔细阅读课本中“全等”符号表示的要求．
Ⅱ．导入新课
将△ABC沿直线BC平移得△DEF；将△ABC沿BC翻折180°得到△DBC；将△ABC旋转180°得△AED．
甲DCABFE乙DCAB丙DCABE
议一议：各图中的两个三角形全等吗？
不难得出：△ABC≌△DEF，△ABC≌△DBC，△ABC≌△AED．
（注意强调书写时对应顶点字母写在对应的位置上）
启示：一个图形经过平移、翻折、旋转后，位置变化了，•但形状、大小都没有改变，所以平移、翻折、旋转前后的图形全等，这也是我们通过运动的方法寻求全等的一种策略．
观察与思考：
寻找甲图中两三角形的对应元素，它们的对应边有什么关系？对应角呢？
（引导学生从全等三角形可以完全重合出发找等量关系）
得到全等三角形的性质：全等三角形的对应边相等． 全等三角形的对应角相等．

专业. Section Ⅳ Discovering Useful Structures——限制性定语从句(3)
定语从句是一种形容词性从句，它是跟在一个名词、代词或句子后对其进行修饰限定的句子。因该从句在整个句子中作定语，故被称作定语从句。被修饰的词叫先行词。定语从句通常只能放在被修饰的词之后。
一、定语从句的关系词
[合作探究]
After listening to the scientists who had studied the problem and citizens who lived
near the dam, the government turned to the United Nations for help in 1959.在听取了研究这个问题的科学家和住在大坝附近的居民的意见后，政府于1959年向联合国寻求帮助。
Temples and other cultural sites were taken down piece by piece, and then moved and
put back together again in a place where they were safe from the water.寺庙和其他文化遗址被一块一块地拆下来，然后搬到一个安全的不会遭受水患的地方重新组装起来。
[自主发现1] 当被定语从句修饰的先行词指人且在定语从句中充当主语时，引导定语从句的关系词用who/that;__当被定语从句修饰的先行词指地点且在定语从句中作地点状语时用关系词where。
二、关系词的基本用法
[合作探究] .
专业. You may have chances to meet new people who will become your lifelong friends.你可能有机会结识将成为你一生的朋友的新人。
In the dark street, there wasn’t a single person whom she could turn to for help.在黑暗的街道上，没有一个她可以求助的人。

Pingyao, in the centre of Shanxi Province, is a famous historic
cultural city of China and a world cultural heritage site. It’s 90
kilometres south of Taiyuan on the Fen River.
People lived in Pingyao during the New Stone Age. Its long period
as a county government seat has left Pingyao with lots of historic
buildings and sites, with a 2,700-year history. Ninety-nine of them
are
under government protection, including Zhengguo Temple, Shuanglin
Temple and Ancient City of Pingyao.
During the Ming and Qing Dynasties, businessmen organised
commercial(商业的) groups that did business nationwide. Shanxi Province
had some of the most important ones and Pingyao was their centre. In 1823,
a store, known as Rishengchang (Sunrise Prosperity), traded in bank
