Look at the letters the children from Viet Nam and Sweden sent to each other in a penfriend project. Why do you think they chose this way to communicate with each other?I think, they chose this way because the penfriend are at least 5 other benefits to letter writing:Reading and writing skills improve as students practice their writing skills and organize their thoughts onto paper.The pen pal develops compassion and understanding of other cultures and values.The pen pal promotes many life skills, including development of social skills.Letter writing promotes patience; delayed gratification!Writing to a pen pal develops a child's curiosity.COMMUNICATION IN THE FUTURE:WHAT IS THERE FOR US?About fifty students in two schools in Ha Noi, Viet Nam and Ume, Sweden have been exchanging letters in a penfriend project since 2013. ‘I love to write. You can even stick something on the letter, like this tiny sweet!’ said Linh, from Ha Noi about the project. From the Sweden end, Anders said, ‘It’s so nice to open and read real letters!’ But will this be our future communication? It’s said that in a couple of decades we’ll be using telepathy and holography. 2. Read the text.Telepathy uses a tiny device placed into our head. Information will be sent and received directly to and from our brains. We’ll be communicating just by thought over the network! Holography, a video-conference technology with three-dimensional images, will help us interact in real time in completely different places.Impressed? Maybe, but not everyone thinks the cyber world will replace the real world. Like the children in the penfriend project, I prefer to chat with my friends over a cup of tea and enjoy their company - life is more meaningful that way.Look at the highlighted words and match them with their meanings..1. immediately, without delay2. to communicate with or react to3. the opposite of a flat image4. the digital world5. a system of connected parts to share informationnetworkin real timeinteractthree-dimensional images cyber world1. What do the students like about the penfriend project?They love to write and read real letters. One student likes to send sweets with the letters as well.2. What are the two ways of future communication mentioned in the text? Explain how they work. They are telepathy and holography. Telepathy uses a tiny device in our head to communicate bythought over the network. Holography gives three-dimensional images and we will be able to interact with each other in real time.3. Do you think the writer is happy with this future of communication? How do you know?She prefers to use real, face-to-face communication because she thinks this makes life more interesting.3. Answer the following questions.SPEAKING4. In small groups, decide whether you agree with the author of this text. Why/Why not? Share your ideas with the class.I agree with the author of this text, because, when we use telepathy and holography, you can:- 	say something to someone who is no longer a part of your life.- 	apologize to someone who is no longer in your life for a misunderstanding or a hurt that you caused.- pave the way for better interaction with someone you don't get along with. Call a truce telepathically and see how the tension in the relationship eases.- 	let someone know how you feel about them if you've been unable to convey this information face to face.- forgive someone who has hurt you cutting the cords of anger or disappointment that bind you.5.	Class survey. What ways of communication do you use for the following purposes now and what will they be in the year 2030?Purpose At present In the year20301. working on a group project I (use) I’ll be(using) 2. keeping in touch with a friend who lives far away3. contacting friends to meet to see a film4. asking your teachersomething that you didn’tunderstand in the lesson5. letting your parents know you want to say sorry6. showing love to your petPurpose At present In the year 20301. working on a group project I use face to face meeting.I will be using video conference meeting.2. keeping in touch with a friend who lives far awayI use letter and email.I will be using video chatting.3. contacting friends to meet to see a filmI use mobile phone.I will be using message board.4. asking your teachersomething that you didn’t understand in the lessonI use face-to-face meeting.I will be using telepathy.5. letting your parents know you want to say sorryI use face-to-face meeting.I will be using telepathy.6. showing love to your petI touch them.I will be using holography.Some suggestions+ HOMEWORK -	Learn the new words by heart. - Read the text on page 44 again.-	Do exercises D1, 2 in workbook (page 32, 33)- Prepare for Unit 10: Skills 2Goodbye!See you again!THANKS FOR YOUR ATTENTION!THANK YOU FOR ATTENTION!the endGOOD BYE!Theo nghĩa hẹp : Hologram là một bức ảnh phẳng mà nhờ sự bố trí các chi tiết sao cho chúng phản xạ ánh sáng một cách thích hợp mà nó nổi lên như một ảnh có chiều sâu (ảnh 3 chiều). Thỉnh thoảng ta bắt gặp các ảnh này được bày bán ở các nhà sách. Các loại tem chống giả hiện nay ở nước ta cũng áp dụng nguyên tắc của ảnh hologram: Khi nhìn tem này dưới các góc nhỉn khác nhau chúng hiện lên màu sắc hoặc chi tiết khác nhau.Theo nghĩa rộng : Hologram là ảnh trình chiếu mà ta có thể quan sát được vật thể dưới bất kỳ góc nhìn nào như thể là có đang ở vật thể ấy ở đó mặc dù ta không thể sờ được. Trong một vài trường hợp người ta dịch gọn hologram là toàn ảnh.Hiểu theo một cách khác : Holography là phương pháp tái tạo hình ảnh ba chiều (3D) của một vật thực qua một bản ghi phẳng hai chiều (2D). Nhìn bản ghi hai chiều bằng mắt thường ở một góc thích hợp và dưới ánh sáng thích hợp ta sẽ thấy hình ảnh ba chiều của một vật thực mà không hề có sự hiện diện của vật thực ở đó. Holography là kỹ thuật thu (ghi) hình của thế giới ba chiều lên môi trường hai chiều và môi trường hai chiều này có thể phát lại hình ảnh ba chiều của vật thực.
