课件43张PPT。warming-up and readingThe technology develops so quickly that many new things appear in human being’s life.Let’s guess what they are:guessing game I am very old now. I was born in China. Many people used me for calculating(计算) in the past, but now I am a bit lonely because they don’t like me now.
Do you know who I am?abacus ['?b?k?s] Guess : I am very small. I can be used for calculating. In China, a lot of students use me when solving mathematical(数学的) problems.
Do you know who I am?Calculator ['k?lkjuleit?] Solve a riddle : one thingIt has a big face with many keysIt has two big ears which can play musicYou can watch TV or see a movie using itIt can be seen in the office, classroom and at home.It can download informationguessDo you know who I am ?
