Archimedes and the golden crown
One day in ancient Greece, King Hiero asked a crown maker to make him a gold en crown. At first, he was very happy with it.
“it’s a nice crown, isn’t it?” he asked his men. Later, howe ver, he began to d oubt that it was a real gol d en crown. “Is it mad e completely of gold?” he wond ered. He sent it to Archimed es and asked him to find out the truth.
“This problem seems difficult to solve. What shoul d I d o?” thought Archimed es. Archimed es was still thinking about this problem as he fill ed his bath with water. When he got into the bath, some water ran over.
“That’s it!” shouted Archimed es. “I know how to solve the king’s problem!”Archimed es went straight to the palace to see the king. First, he weighed the crown and asked the king for some gol d of the same weight.
Next, he put two pots into two big bowls and filled both pots with water. He put the gol d into one pot and some water ran into the bowl. Then he put the crown into the other pot. This time, even more water ran into the bowl.
“Look at this,” said Archimed es to King Hiero. “A crown mad e compl etely of god displaces l ess water than a crown mad e of gol d and another metal. This crown displaced more water than gol d and another metal. This crown displaced more water than gol d of the same weight, so I’m certain that it’s not compl etely mad e of gold.”
“The crown madd er tricked me , didn’t he? What a bad man he is!” shouted King Hiero. He then sent the crown maker to prison.

One day, Sun Quan sent Cao Cao a present. It was a huge elephant. Cao Cao wanted to find out the weight of the el ephant.
“What a huge animal it is! Can anyone tell me how to weigh it?” he asked the crowd around him.
“Can we get a large scale?” asked a sol dier. However, no one coul d find a scale large enough.
“Can we cut it up？” asked another soldier.. “No. I d on’t want to kill it,” said Cao Cao. Just then, young Cao Chong had a wond erful id ea. “I can weigh the elephant!” he said “l et me have a try.”
Cao Chong asked some sol diers to l ead the elephant onto a boat. As the heavy animal walked onto it, the boat went l ower into the water. Cao Chong drew a line on the sid e of the boat to mark how l ow it went. The elephant was then taken off the boat and the boat was filled with rocks until it went d own again and water reached the line on the boat.
Cao Chong then weighed the rocks. He ad d ed up the weight of all the rocks and said, “This is the weight of the el ephant.”
Cao Cao was very happy with his son. “My son is very cl ever, isn’t he” he said. Everyone agreed.

Two geniuses
Many peopl e consid er Albert Einstein(1879-1955) a genius. This story about him shows that he also had a sense of humour.
Einstein often received invitations to explain his theories at different universities. On these trips, his driver Hans often said to him, “It’s a pl easure to drive a genius like you, Dr Einstein.”
One evening, on their way to a university, Einstein said, “ I’m so tired. I wish I coul d avoid giving my lecture tonight, Hans, but I d on’t want to l et my audience d own.”
“I know what to d o,” said Hans. “ I can give the l ecture for you. You can trust me. I’ve listened to your l ecture so many times that I’ve l earnt it by heart. No one knows you at this university, so they won’t find out.”
So, they changed places. T the university, Hans was guid ed to the front of the hall. Einstein took a seat, listened to Hans give his l ecture without difficulty, and joined in the applause at the end.
However, before Hans l eft, a man shouted, “I’d like to ask you a question.” He then asked a question so difficult that Hans had no id ea what he was talking about. Einstein turned pale. “Oh no!” he thought. “Now we’re in troubl e. “But Hans just laughed and said, “That’s such an easy question that even my driver can answer it. Hans, pl ease …”
Einstein stood up and answered the question perfectly.
They l eft the university, with Einstein driving. A little later, Hans offered to drive. “No,” laughed Einstein, “It’s a pl easure to drive a genius like you, Hans.”

Einstein and the little girl
One afternoon, Einstein was walking home from work. At the same time, a 12-year-old girl was walking home from school. They were soon walking sid e by sid e. The girl l ooked at him curiously from time to time.
“Pard on me,” the girl said, “but you l ook just like Albert Einstein.”
“That’s because I am Albert Einstein!” Einstein said.
“I d on’t believe you,” the girl said. “Everyone knows that Einstein is a genius,. But you’re wearing your sweater backwards, so you can’t be very cl ever.”
Einstein began to lau gh. “You’re the first person to be so honest with me, “he said
to the girl. “it’s a pl easure to hear someone tell me the truth about my look.”
After that day, the girl often went to visit Einstein’s house after school. One afternoon, the girl’s mother went to visit Einstein. She asked him why he spent so much time with her daughter.
“Our friendship is easy to explain,” Einstein said. “Your daughter tells me the truth about my l ook and brings me cookies. In return, I help her with her Maths homework.”

牛津深圳版六年级上册英语教学计划
教学工作计划 英语教学工作计划 一、班级基本情况分析： 本学期我担任六年级1班和2班的教学任务，从总体来看，这两个班学生英语基础较弱，对英语学习的兴趣较低。词汇和语法掌握不牢固。在语音语调模仿的正确性以及听说读等学习习惯养成等方面还需通过师生共同努力。 本班大部分学生活泼好动，但是有些自制能力较弱，有一些优秀生，他们有较好的英语基础，对英语的理解力也较强，语音语调较好。一部分学生听说读写的英语学习习惯较差，但还有个别特殊生，英语基础十分薄弱，听课效率较差，影响课堂效率。 二、教材内容分析： 《牛津英语深圳版》六年级采用模板建筑式编写，将语言材料和语言技能有机结合，并注重各模板在横向学习内容上循序渐进，在纵向语言知识和技能上滚动和复现。教材由内容相对独立但具内在联系的四个模板（module）组成，每个Module分三个Unit，每个Unit 主要分成以下部分：Look and say, Read a story, Think and say/Make and write/Learn and sounds, Listen and say的内容包括每课的核心句型，要求学生在情景中说话，也就是在Situation中运用。Read a story的内容是每课的核心词汇，要求学生能听懂、认读并放入情景中去操练和巩固，简单运用地说。Think and say/Make and write
是为了巩固以上几个部分而设计的和活动。Think a song/Culture corner是为提高学生学习兴趣、调节学习情绪而编排的Song, Rhyme 等，同时也能达到巩固复习的目的。Learn the sounds是让学生学习音标。 三、主要教学目标： 知识目标: 1. 语音: 学习和掌握单词的发音规则,并能加以区分和比较,以后的英语词汇学习打下基础做好准备. 2. 词汇: 能根据单词的分类学习，记忆单词，正确理解词义。能列举与所学单词有相同性质，或相同意思或相反意思的单词(也就是指同类词,近义词和反义词)，并掌握一定的词法，更加重要的是要掌握单词语用功能,从而使学生能够正确恰当的来使用习得的词汇，避免出现只会拼读而不会使用情况。 在每一个单元中都会有出现先前学过的单词,对这些词就应该注重词与词之间的比较,或者是可以根据学生的实际情况进行拓展。 3. 句型: A. 对各类句型和语法(一般疑问句，特殊疑问句，过去式，代词等)进行整理，如：How was.../Did you...?/there were.../shall we...? ；以及这些句型的不同句式变化(肯定,否定,一般疑问和特殊疑问). B. 学习关于数字、外贸、能力、国家、方向、等词汇的表达，并适
