1. How do you think these events or such technology might develop in the future
2. What challenges might they bring
3. What opportunities might they bring
Step 2 : 问题导学(5')
Future development:
Challenges:
The AI is programmed to do something beneficial, but it may develop a destructive method for achieving its goal.
Opportunities it may take:
People can use the AI to do most of the daily chores.
More and more people can be free to do work of creating new things.
Future development:
Challenges:
Opportunities it may take:
More nanobots will be created to help doctors to find out the root of a disease and make operations more accurately.
New kinds of virus may appear and even nanobots can’t find out where they come from.
The nanobots may bring more people’s life back.
Future development:
Challenges:
Opportunities it may take:
Work in factories will be more efficient. More labor force can be freed from working.
More and more workers will be out of work.
People will learn more about how to create a machine and how to operate it to help work.
Future development:
Challenges:
Opportunities it may take:
More animals even human beings will be cloned.
Cloning may result in disorder on the earth.
More lives will be saved and more diseases can be cured.
Future development:
Challenges:
Opportunities it may takes:
Air pollution will be decreasing. There will be glaciers again in the Arctic Ocean.
There may be other threats to the Polar bears.
People can live in harmony with the Polar bears.
3. Listen to a radio interview with Dr Han and
Vincent Black giving their predictions about the
future, and then fill in the table below.

computer scientist
Computers will be cleverer than us in the future; people will also be programming computers to think like humans; we'll be programming them to not think in ways that may harm humans; we'll also be creating machines to help people internally.
architect
There will be cities floating on water and people could move into housing in cities that float.
Listen for predictions
When listening for predictions, you should listen for the use of the future tense, in particular the future tense with will or will be doing. Words such as predict, prediction, and forecast, are also used quite often when making predictions.
Step 3: 点拨精讲(23')
Tapescripts
Host: On today's episode of “Future Changes”, we talk
with two experts from different fields, Dr Han and
Vincent Black, to hear their predictions about the
future. First, Dr Han, could you please tell our
audience what you do
Dr Han: Certainly. I'm a computer scientist.
Host: And could you please tell us your prediction
Dr Han: Yes, well, I forecast that computers will be
cleverer than us in the future. I think that
people will also be programming computers to
think like humans.
Host: That's very interesting, but aren't you worried
that such computers would be dangerous
Dr Han: Not at all. This is because we'll be programming
them to not think in ways that may harm humans.
In fact, we'll also be creating machines to help
people internally. For example, I think scientists
will put some small intelligent machines, called
nanobots, inside our bodies to increase our
abilities.
Host: Wow! That would make each one of us
superhuman! And Vincent, could you please tell
us about your job
Vincent Black: Certainly. I'm an architect, I design buildings.
Host: And what is your prediction about the buildings
of the future
Vincent Black: It's about the cities of the future, actually.
I believe that cities floating on water are part
of the world's future.
Host: Oh, really What might make us want to do that
Vincent Black: Yes. With global warming causing polar ice
to melt, the sea level rising by many metres
is a very realistic prospect. Instead of moving
people away from the sea, I think that people
could move into housing in cities that float.
Host: That sounds very innovative. Could you
please give us more details
Vincent Black: Sure. Well, I've developed a plan by designing
a city that borrows many ideas from the giant
water lily, a flower that floats on water.
Moreover...
4. Discuss whether you think Dr Han and Vincent
Black's predictions are possible.
Why or why not
Post-listening
Suggested Answers:
I agree on Dr Han's idea that computers will be cleverer than us in the future. Actually there are already computers, like AlphaGo, that are smarter than most people.
I don't agree on Vincent Black's idea about floating cities, because I doubt that sea levels will rise that much.
5. In groups, brainstorm about the future.

Sample Dialogue
A: Good afternoon, Ms Zhang. Thank you for agreeing to
do this interview.
B: I'd love to.
A: First, could you please tell our audience what you do
B: Certainly. I'm a doctor. I perform transplant surgery
every week.
A: That sounds like a very high-tech job. How do you think
the surgery will be operated in the future Do you have
any predictions about that
B: Yes, well, I believe that doctors in the future will have
much better means to help people. I can imagine that
nanobots will be put in patients' body to detect the illness.
Sample Dialogue
And in the future, there will be adequate suppl of organs
for patients who need transplant.
A: Well, that would be really good news for all of us.
Could you please explain how this will be possible
B: Well, it will be possible because of special 3D printers.
In the future, doctors will be using them in hospitals
regularly to create healthy copies of people's organs.
Then they will replace the unhealthy organs with the
healthy copies.

Dear Editor，
Recently our class has had a discussion about whether the clone research should be carried out.

Some students are for the clone research.They say cloning is helpful in researching into the cures for many diseases as well as useful in saving the endangered animals.Cloning could also offer perfect organs for patients to transplant.

However，others are against it.Though clone would improve the quality of life，it might bring about some genetic changes，and have some bad physical and psychological effects.What’s more，it might also raise ethical problems.
Personally，cloning should be dealt with carefully and monitored closely by government.Because we do not understand enough what effects cloning will have on the world in the future.
