老师：Affiliated to Beijing Normal University. Welcome to today's online lesson. In today's lesson, we will go on learning Unit 4 and focus on another passage in developing ideas, arts and technology. As we can see from the title, the main content of the passage is something about the relations between art and technology. By learning this passage, you will be able to get the main idea and specific information of the passage. And then you will be able to understand the changes brought about by the development of art and technology. And No. 3, you will be able to relate the developments of arts and technology to your real lives.
老师：Before we start learning the passage, I will play a video related to the topic. You are supposed to watch the video attentively and answer the following questions.
