Read the article and write answers to the questions.Who invented tea?Do you know that tea, the most popular drink in the world（after water）, was invented by accident? Although tea wasn’t brought to the Western world until 1610, this beverage was discovered over three thousand years before that. According to an ancient Chinese legend, the emperor Shen Nong discovered tea when he was boiling drinking water over an open fire. Some leaves from a nearby bush fell into the water and remained there for some time. The emperor noticed that the leaves in the water produced a pleasant smell. Later he decided to taste the hot mixture. It was quite delicious. And in this way, one of the world’s favorite drinks was invented.ReadingDo you know when basketball was invented?If you travel around China you will notice a very popular activity everywhere you go— basketball. This much-loved and active sport is enjoyed by all, for fun and exercise.The sport of basketball is a little more than a hundred years old. It is played by more than 100 million people in over 200 countries including China, where basketball has been played in parks, schools, and even in factories.Basketball was invented by a Canadian doctor named James Naismith, who was born in 1861. When he was at college, his class was once asked to invent a new game that could be played indoors during the long winters. Dr Naismith created a game to be played on a hard wooden floor, so the safety of the players was important. Knocking into players and falling down would be dangerous.Dr Naismith divided the men in his class into two teams, and taught them how to play his new game. The aim of basketball is for players to try to get a ball intothe “basket”: a net hanging from a metal hoop. Players shoot from below the basket, and sometimes the “backboard” is used for guiding the ball into the basket. Players move towards one end of the court while throwing the ball to each other.It is believed that on December 21st, 1891, the first basketball game in history was played. Then in 1936/ in Berlin, it became an Olympic event. A team from China took part, and although they didn’t win they used the experience to help develop the game at home. Since then, the popularity of basketball has risen worldwide, and the number of foreign players in America’s NBA （National Basketball Association）has increased. Basketball has also become a more popular sport for people to watch, and many young people dream of becoming famous basketball players.。

人教版九年级英语Unit 9 When was it invented SectionA 英文 说课稿
Unit 9 When was it invented? SectionA 英文说课稿A. Teaching material analysis:1. My topic today is 1a-2c of section A in Go for it Unit 9. The language goal of this unit is “Talk about the history of the inventions”. The key words are:scoop, adjustable, heel, battery, operate, slipper, bulb, invent, be used for.2. The key expressions listed as follows :When was the car invented? It was invented in…Who was the car invented by? It was invented by...What is it /are they used for? It is/They are used for...3. The difficult point is the new language function of passive voice.B. Teaching anticipationIt’s the first time for the students to get in touch with the passive voice. This grammar item is a key point also is a little bit difficult. In this period, I will mainly let the students touch with the passive voice. They realize initially what the passive voice is constructed and what it expresses. That will be OK. I make "talk about the history of inventions" as the language goal of the class. In our school, the students don't have much time to learn some inventions. So I ask them to get ready for this lesson and try to find information about the four greatest inventions of ancient China and some other famous inventors and their inventions. So they can have a concert of what they will learn in this class. I hope the students can hit the following goals after this class:1. They can realize the passive voice initially.2. They can use the sentence structures learned to discuss the inventors and their inventions.3. They can realize the ancient civilization of China, strengthen the proud of feeling.C. My thought for the design of this classIn this class, I will lead the students to have a tour to an African original tribe and recommend some inventions in our daily life to improve their originality situation, thus develop the topic. The activities involve three key sentence structures of this lesson:When was it invented?Who was it invented by?What is it used for?My post task is a letter from a student to Africans. It introduces the ancient four greatest inventions of China. But there are many mistakes about the passive voice. I get the students to correct them. Through the practice, the students can consolidate what they lea rned today. What’s more, it can make the students realize the glorious and ancient civilization of China.D. Teaching procedures:Step 1. Warming upI present the language targets on the first page of ppt. It can make students realize what they are going to learn before class. So they will have a better effect to learn it well.Step 2. Lead-in1. T: Today we are going to Africa. We'll visit an ancient tribe. (Present the African original tribe picture)T: They live in the house like this. (A dark house) What do they need?S: Bulb.Present the bulb that student said. Explain that this is an inventionT: It’s a kind of invention.2. Present Edison’s picture,T: Who is this man? (Edison)S: He was an inventor.( Present the vocabulary inventor)T: He invented many inventions.Please say something about Edison and the bulb.S: Edison invented the bulb.(The student can describe with the active voice which learned before)Then change the positions, and then let the student say the relation again.(Design aim: I want to make the students find out what the passive voice is. It will develop the ability of independent study)3. Repeat the same steps with some other inventions (car and telephone).Step 3. Activity1T: The Africans want to know when the inventions were invented.1. Order the inventions (1a)Get the students to guess in what order the inventions were invented and number them from 1-5. They can discuss with their partners:S1: I think the telephone was invented before the car.S2: Well, I think the car was invented after the telephone.2. Listen to the tape and find the time of the inventions. ( 1b )Then check the answer and know whose order is right.3. Pairwork (1c )Make conversations using the timetable in 2a.(Goal: do 1a-1c. withdraw the knowledge dot and practice.)Step 4. Activity2 Have a tryT: Let’s learn some other inventions.- When was the laser invented? - It was invented in …- Who was it invented by? - It was invented by …inventions When was it invented? Who was it invented by?Laser 1960 Tonysairplane 1903 LightE-mail 1971 Tomlinsontelegraph 1895 Marconiair-condition 1902 Wailersauto-dub machine 1967 Belonball pen 1938 Parishes(Goal: practice the key sentence structures with some other inventions and open the students mind at the same time)Step 5. Activity3 What are they used for?T: The Africans know when the inventions were invented. And they want to know what they are used for.Show a conversation between Bell and an AfricanAfrican: What’s the telephone used for?Bell: It’s used for talking with people.1. What are they used for? (Present a sheet of inventions)1) Discuss in groups of four.2) Get the students to guess. They can have their own ideas.2. Guessing gameDivide the whole class into two groups and have a competition.

It's used for consolidating the key sentences and passive voice.)Step 6. Activity4 ReadingT: The Africans are very glad to know so much about the inventions. So they’d like to read some other articles about other modern inventions.Give the listening material and the forms to the students before class1.
