Why did the population grow very slowly in the beginning, and why is it now growing faster and faster?
A long time ago, many babies died when they were only a few days or weeks old. If people grew up, many didn’t live for very long. Why? Sometimes they didn’t have enough food. Sometimes their food didn’t make them strong. But, most importantly, people became ill very easily. There were no hospitals or doctors, and people often died young.
But what will happen if the population doesn’t stop growing? We will have to use farm land to build houses. There will be no animals or plants or trees. Then there won’t be enough food in the world for everyone.

Most of middle school students agree that school life is rich and colorful and learning is very interesting and enjoyable .However, some of the students, either in cities or in the countryside feel tired of their study at school. It is a very serious problem in our society, but why?
Some of them think that education at school is useless, the subjects they learn have nothing to do with their interest or even their future .Little by little, they lose their interest in study or even get tired if it .In the end they find it too hard to go on with their study and finally lose confidence in their study and give it up.
In my opinion, learning is very important on the life road to success for our future .Marx told us that books are the ladders to progress for mankind, so I think we should stick to our learning, however hard it is or whatever difficulty we meet in our life.

必修2《平面解析几何初步》教材分析 一、《课程标准》关于平面解析几何初步的表述 解析几何是17世纪数学发展的重大成果之一，其本质是用代数方法研究图形的几何性质，体现了数形结合的重要数学思想。在本模块中，学生将在平面直角坐标系中建立直线和圆的代数方程，运用代数方法研究它们的几何性质及其相互位置关系，并了解空间直角坐标系。体会数形结合的思想，初步形成用代数方法解决几何问题的能力。 在平面解析几何初步的教学中，教师应帮助学生经历如下的过程：首先将几何问题代数化，用代数的语言描述几何要素及其关系，进而将几何问题转化为代数问题；处理代数问题；分析代数结果的几何含义，最终解决几何问题。这种思想应贯穿平面解析几何教学的始终，帮助学生不断地体会“数形结合”的思想方法。 平面解析几何初步（18课时） （1）直线与方程 ①在平面直角坐标系中，结合具体图形，探索确定直线位置的几何要素。 ②理解直线的倾斜角和斜率的概念，经历用代数方法刻画直线斜率的过程，掌握过两点的直线的斜率计算公式。 ③能根据斜率判定两条直线平行或垂直。 ④根据确定直线位置的几何量，探索并掌握直线方程的几种形式（点斜式、两点式及一般式），体会斜截式与一次函数的关系。 ⑤能用解方程组的方法求两直线的交点坐标。 ⑥探索并掌握两点间的距离公式、点到直线的距离公式，会求两条平行直线间的距离。 （2）圆与方程 ①回顾确定圆的几何要素，在平面直角坐标系中，探索并掌握圆的标准方程与一般方程。 ②能根据给定直线、圆的方程，判断直线与圆、圆与圆的位置关系。 ③能用直线和圆的方程解决一些简单的问题。 （3）在平面解析几何的学习过程中，体会用代数方法处理几何问题的思想。 （4）空间直角坐标系 ①通过具体情境，感受建立空间直角坐标系的必要性，了解空间直角坐标系，会用空间直角坐标系刻画点的位置。 ②通过表示特殊长方体（所有棱分别与坐标轴平行）顶点的坐标，探索并得出空间两点间的距离公式。 二、教学大纲与课程标准的比较

Unit1 IN SEARCH OF THE AMBER ROOM Frederick William ,the King of Prussia , could never have imagined that his greatest gift to the Russian people would have such an amazing history . This gift was the Amber Room , which was given this name because several tons of amber were used to make it . The amber which was selected had a beautiful yellow-brown colour like honey .The design of the room was in the fancy style popular in those days.It was also a treasure decorated with gold and jewels ,which took the country's best artists about ten years to make . In fact, the room was not made to be a gift .It was designed for the palace of Frederick .However, the next King of Prussia , Frederick William Ⅰ, to whom the amber room belonged, decided not to keep it.In 1716 he gave it to Peter the Great. In return , the Czar sent him a troop of his best soldiers.So the Amber Room became part of the Czar's winter palace in St Petersburg. About four metres long, the room served as a small reception hall for important visitors . Later, Catherine Ⅱ had the Amber Room moved to a palace outside St Petersburg where she spent her summers. She told her artists to add more details to it .In 1770 the room was completed the way she wanted .Almost six hundred candles lit the room ,and its mirrors and pictures shone like gold. Sadly , although the Amber Room was considered one of the wonde rs of the world , it is now missing . In September 1941, the Nazi army was near St Petersburg . This was a time when the two countries were at war.Before the Nazis could get to the summer palace , the Russians were able to remove some furniture and small art objects from the Amber Room . However , some of the Nazis secretly stole the room itself .In less than two days 100,000 pieces were put in side twenty-seven wooden boxes .There is no doubt that the boxes were then put on a train for Konigsberg, which was at that time a German city on the Baltic Sea . After that, what happened to the Amber Room remains a mystery . Recently, the Russians and Germans have built a new Amber Room at the summer palace. By studying old photos of the former Amber Room , they have made the new one look like the old one. In 2003 it was ready for the people of St Petersbu rg when they celebrated the 300th birthday of their city. 单词： Unit 1 △ cultural /'k?lt??r?l/ adj. 文化的 △ relic /'rel?k/ n. 遗物；遗迹；纪念物 rare /re?/ adj. 稀罕的；稀有的；珍贵的 valuable /'v?lju?bl/ adj. 贵重的；有价值的 survive /s?'va?v/ vi. 幸免；幸存；生还 vase /vɑ:z/ n. 花瓶；瓶 dynasty /'d?n?st?, 'da?-/ n. 朝代；王朝 △Taj Mahal /ta:d? m?'ha:l/ 泰姬陵 △ ivory /'a?v?r?/ n. 象牙 △ dragon /'dr?ɡ?n/ n. 龙 △ amber /'?mb?/ n. 琥珀；琥珀色 in search of 寻找 △Frederick William I /'fredr?k 'w?lj?m e?
