介绍:
The last class of the week...
The start of a new lesson!
“Back to the Future”
Today we’re going to talk about the past, the present, and the future!
Has anyone seen the movie, “Back to the Future”?
Page 58
I recommend it, it’s very good
Transportation, Communications, Entertainment.
Lets start with transportation.
railroads and ocean liners
That’s an ocean liner
What does it mean, “commercial space flights”
Does anyone know?
No no .. that’s not a warship !
That’s for passengers
Military could be another category to look at the past, present, and future.
The ship is for people to travel, it’s not a military ship.
Be careful everyone: In the past we HAD the telephone and the postal system
In the present we HAVE cell phones and email
Virtual reality = 虚拟现实
Yes, VR for short
It’s a very popular trend right now.
Thats the question I was going to ask
Do you think any of the future developments will happen in your lifetime?
Almost all of the things have happened already
Do you think you will have a robot assistant in your lifetime?
Yes, “telecommuting” (working from home) is also a popular trend these days.
Before we continue, I will ask you one more question...
How do you think clothing will be different in the future?
self-adjust to the temperature?
The clothes can change according to the environment... that’d be great.
But I still didn’t get the first word...
The clothing of the future will be multifunctional, it can easy protect us from the sun, rain, and other weather.
multifunctional (adj)
Especially with the Internet of Things (IoT) technology
Our clothes may be connected to the Internet.
Let’s read the conversation!
So we’ll review your answers on Monday
And we’ll also do part B of Section 3 on Monday
