Unit 4 Living with technology
Extended reading（教學設計）
I. Learning objectives
By the end of the lesson, students will be able to:
1. grasp the general information of the dialogue;
2. deeply understand the dialogue;
3. learn and use the core vocabulary;
4. analyse some complex sentences.
II. Key competence focus
1. Get Ss to review some strategies learnt before.
2. Learn how to find the references.
III. Predicted area of difficulty
1. Find the references.
2. Analyse the complex sentences.
IV. Teaching procedures
Step 1 Reading
1. Reading for the structure of the text.
T revises the techniques learnt in Lesson 2 to conclude a paragraph.
T: There are two ways to boil a paragraph down. One is “brief”, using as few words as possible; another is “descriptive”, offering important information.
T: Now try the “brief” to conclude the text.
Title Virtual reality
Definition
Function
Application
Barriers
Future
T: Now turn to page 54. Let’s come to part A and try the “descriptive” way to conclude the text.
What VR is
How it works
Applications
Barriers
Future
2. Reading for extended information.
T: What other applications of VR do you know about

Step 2 Building core vocabulary
1. practical
Definitionsa. connected with real situations rather than with ideas or theoriesb. useful or suitable Vocabulary webpractise→practice→practical→practicallypracticable
T: Match the underlined words with their right definitions.
1) Your invention is interesting, but not very practical.
2) It’s an interesting idea in theory but there are many practical difficulties in reality.
3) Can you give some examples of the practical applications VR has
2. engage
Definitionsa. to employ sb to do a particular jobb. to begin fighting with sbc. to succeed in attracting and keeping sb’s attention and interestd. when a part of a machine engages , or when you engage it, it fits together with another part of the machine and the machine begins to work e. to become involved with and try to understand sth/sb Vocabulary webengage→engaged→engagementbe engaged in
T: Match the underlined words with their right definitions.
1) The two cogwheels (齒輪) engaged and the machine started.
2) Nothing engages his attention longer than reading novels.
3) She has the ability to engage with young minds.
4) Our school has engaged a foreign teacher as a spoken English teacher.
5) The two armies were fiercely engaged for several hours.

3) The plate was one of a pair, but I broke its twin.
4) The prison service has the twin goals of punishment and rehabilitation.
5) What if I told you that doctors could create a virtual “twin” in order to practise delicate surgery before attempting it on the patient (Lines 24-26 P53)
4. clone

3) Although two clones are identical genetically, they may develop in different ways.
4) When shopping online, you can look forward to being able to have your own virtual reality clone try on clothes and to see products with 360-degree views. (Lines 37-39 P54)

Step 3 Finding out reference
T asks Ss to explore what the underlined nouns or pronouns refer to.
T: To understand the precise meaning of a reading material, we have to dig out the reference of a noun or a pronoun. Here are some sentences from the text. Let’s explore what the underlined nouns or pronouns refer to.
1. It really boils down to three things—time, cost, and technical limitations. We will need time to develop and fine-tune the hardware and software. The initial cost will discourage most people in the beginning but that should be fixed over time. (Lines 45–48 P54)
T: What does “that” refer to
2. Fox example, 5G technology, with its potential to serve up more stable mobile connectivity at faster speed, will make it possible for people to enjoy a more immersive VR experience wherever they are. (Lines 54–57 P54)
T: What do the three underlined parts refer to
【設計意圖：指代關系是閱讀難點之一，準確理解名詞和代詞的指代是順利理解上下文的前提。本文中多處出現復雜的指代，需要借助文理、語法才能準確理解。】
Step 4 Analysing the complex sentences
T helps Ss to find out some complex sentences and asks some of them to analyse their components.
T: There’re some complex sentences in the text. To understand the meaning, you have to analyse their components.
1. When you wear a VR headset equipped with sensors and a screen, you are surrounded by three-D images, sounds and other sensory information, which creates a super-realistic effect called “presence”. (Lines 5-8 P53)
2. What if I told you that doctors could create a virtual “twin” in order to practise delicate surgery before attempting it on the patient (Lines 24-26 P53)
3. They’re well equipped to become part of a technological generation that will develop and use VR to do things we might think impossible today. (Lines 59-61 P54)
【設計意圖：高中重要語法項目已學習完畢，借助語法分析有助于學生更準確地理解句子意思，實際上本冊課本已出現不少長而復雜的句子，幫助學生進行長句分析很有必要。】
V. Homework
1. Revise the core vocabulary.
2. Read the text again and discuss the question: what future development do you think VR will have
