Think Focusing on culture Computer technology develops quickly and has changed our world greatly. Let's explore the history of computers Read the text to find out how computers have developed over the years. The story of the computer A computer is any machine that can be programmed with a set of instructions. 1837 In Britain, the first machine with a program was designed by Charles Babbage and his student Ada Lovelace. Charles wanted a machine to add up big numbers, but Ada realized that a computer program could do a lot more. She was the first computer programmer. 1936 British scientist Alan Turing read Ada's ideas and created the Turing machine, the basic design of a computer system. The Turing machine could do all kinds of calculations, and it could also run different programs. This is the basis for all modem computers. 1940s Scientists built early computers in England and Germany. They were the size of a room! 1981 A US company designed the first PC (personal computer) for the general public. Experts didn't believe that anybody wanted a computer at home. But in two years they sold thousands of them. 1971 Ted Hoff was the main inventor of the microprocessor, or “microchip”. This was a major breakthrough in the history of computers. Thanks to the microchip, computers and other electronic devices got faster and smaller very quickly. 1990s - present Smartphones—phones with computer software—arrived! Today’s smartphones can connect to the internet and run all kinds of different apps -in other words, they are small computers. The arrival of smartphones has started a new era in digital technology. Expressions such as “Wi · Fi” “download” and “app” have become part of our daily lives. The future Computer technology continues to develop. Some computers will be tiny—perhaps we will even have computers in our clothes. Scientists believe that quantum computers (量子计算机) will be the next big breakthrough. They will be many times faster than today's computers, and much more powerful.

Over to you 4 How have smartphones changed our daily lives? How will they continue to change our daily lives? Share your ideas with the class. Smartphones have changed our lives a lot. First, they help us stay in touch with others easily. For example, we can chat with friends on WeChat or make video calls anytime, anywhere. Second, they make studying easier. We can use apps to look up words, watch online lessons, or do homework. Also, we can shop online, pay bills, and even order food with smartphones. In the future, smartphones may change our lives more. Maybe they can check our health. For example, they can tell us if we don’t sleep well or need to exercise. They might also help us travel better—for example, showing the best way to avoid traffic jams. Some day, smartphones could even connect to our home devices, so we can turn on the air conditioner or lock the door from far away. In short, smartphones make our lives convenient now, and they will bring more surprises in the future! Cross-curricular connection I Information technology Literacy is the ability to read and write. Nowadays, we also talk about digital literacy： In today's world, this is a very important skill. Read the article about digital literacy and tick (√) the correct statements about it. Digital literacy What is digital literacy? Here are a few important parts of digital literacy. Finding and using digital content It is easier to find information online than in print books. However, we need to be careful when we look things up on the internet. Firstly, there is a lot of subjective information online, so we cannot trust everything we read. Secondly, there is so much content on the web, and this makes it difficult to evaluate(评价) information, and it is easy to form biased(片面的) opinions. Creating digital content Today, we also create new content online. Writing posts and comments is an important way to communicate online. The things we publish on the internet contain more than just text. We can also use emojis, pictures and videos to express ourselves. This makes our online messages more interesting to read. Communicating and sharing content When we write emails, posts and comments, we can communicate with a large number of people. The internet is a very powerful tool, but we need to use this tool in a good way. We should always be kind to others online, especially people we do not know. If we communicate in the right way, we can have a positive effect on people's lives. On the other hand, we can hurt others with mean comments online. Digital literacy means the ability: to find and use reliable online information. to read e-books. to create online content, such as writing posts and blogs. to chat online with family and friends. to share ideas and communicate with others online. to behave well online. 1.What is digital literacy mainly about? A. Only the ability to read physical books. B. Skills related to digital information, like finding, using, creating and communicating online. C. Just how to chat with family online. D. The way to buy things on the Internet. 2.When finding digital content, we need to be careful because ______. A. there is no information on print books B. online information is all subjective and unreliable C. there’s much content and subjective info online, hard to evaluate D. we can’t find useful things on the Internet II True or False 1.Digital literacy is not an important skill in today’s world. 解析：文中明确说 “In today's world, this is a very important skill.”，所以该表述错误。 2.When creating digital content, we can only use text to express ourselves. 3.We should always be kind to others online according to the article.

In this project, you are going to make a list of rules for using digital devices at home. Step 1 How do the members of your family use digital devices at home? Complete the table below. Step 2 Work in groups. Compare how you and your family members use digital devices. Then make a list of rules for using digital devices at home. • How much time may each family member spend on their digital devices per day? • What should / may they use their digital devices for? • Should there be a “device-free” time every day? Why / why not? • Who is responsible for checking that everyone follows the rules? • What happens if someone breaks the rules? Step 3 Discuss the rules with your parents. Then revise them based on their suggestions. Step 4 Introduce the rules at home. Keep a journal for a week and note down how well the rules work. Family rules Who is responsible? If someone doesn't follow the rules, we will... Date： Checked by： Step 5 Discuss your results in groups. How well did the rules work? Did they make any difference? Share your findings with the class.
