Can you put them in an order according to the time when they appeared? After reading the passage, check to see if you were right. ( 2 ) analytical machine ( 5 ) laptop ( 1 ) calculating machine ( 6 ) robot ( 4 ) PC ( 3 ) universal machine The main idea of the passage: history of the This is a short ________ ______________ development of computers. True or False? F 1. In 1642 I began as a calculating machine F 2. T 3. T 4. F 5. and could solve any calculating mathematical problem. My real father was Charles Babbage, who Alan Turing wrote a book and build me in 1936. After I got my new transistors in the 1960s, I became smaller but cleverer and quicker. I was brought into people’s homes in the 1970s. Since my birth I have been built to take the place of human race. serve Consolidation 1. “I” in the passage refers to _______. A.A TVset B. A computer C. A radio D. The internet 2.When was the computer the biggest? A.In 1642 B.In 1936 C.In the 1940s D.In the 1970s 3.How old is the computer? A.About 370 years old B About 270 years old.

Comprehending 1 Finish the timeline below 1642 The computer began as a calculating machine. 1822 The analytical machine was made by Charles Babbage. 1936 The computer grew rapidly both in size and in brainpower. 1940s Computers had grown as large as a room. The first family of computers was 1960s connected to each other. 1970s Computers were used in offices and homes. now Computers connect people all over the world together. 2 Complete the chart below Topic sentence Paragraph1 Paragraph2 Paragraph3 Over time I have been changed quite a lot.

Then in 1822, the Analytical Machine was made by Charles Babbage. It could follow instructions from cards with holes. In 1963, Alan Turing, the real father of computers, wrote a book about how the computers could be made to work as a “universal machine” to solve any difficult mathematical problem. Later, people discovered the computer had “artificial intelligence”. In the 1960s, the computer had his new transistors. Its size was totally changed at that time. And in the early1960s, the first family of computers were connected to each other. In 1970s computers have brought into people’s homes. Now computers have been used by billions of people to deal with information and communicate with each other around the world by the Internet. convenient laptop smaller desktop palmtop Discussion 1.What can the future computer be like? 2.What can we do by computer in the future? virtual keyboards 虚拟键盘 Nose-top keyboard-vest You are given a chance to design a computer for yourself.
