Activity 3.
Read the opinions and match them to the persons.Talk about the opinion you agree with.
Activity
I can’t understand why some people worry so much. I hope more breakthroughs in AI will be made soon, so that we can enjoy more and more convenience.
I admit that more advanced AI could be helpful in solving the world’s problems, but there is a high level of risk involved.
We all need to learn to live with AI technology whether we like it or are concerned about it. We cannot stop the march of progress.

Using language
Activity 1. Look at the sentences from the reading passage and answer the questions.
Activity
1　Why is 50 per cent singular in sentence（a） but plural in sentence（c）
2　What are the subjects in sentences（b）and（d） Are they singular or plural
Because in sentence (a), the part “50 per cent” is followed by the uncountable noun “time”, while in sentence (c), the part “50 per cent” is followed by the countable noun “job” in its plural form.
In sentence (b), the part “Every recommendation” is the subject. In sentence (d), the part “none of us” is the subject. Both are singular.
Activity 2. Complete the passage by choosing the singular or plural form.
Activity
Nowadays,some companies offer genetic testing for children’s talents. A large number of clients have/has been attracted to it. They are parents,eager to know what talents their children may have in the future. The process is simple. Every child provide/provides a small sample of blood or body tissue. This is/These are analysed. Each of the children is/are given a report showing their possible talents. A recent example cited on the website is that one of the testing companies compare/ compares the talents of twins Bobby and Benny. Bobby was assessed and his talents was/were revealedto be mostly scientific: a 66% chance of success in chemistry and 54% in physics was/were shown. Meanwhile, Benny’s highest score was/were shown to be in an arts subject: the test gave him 68% for literary studies. Is genetic testing reliable Some scientists say that more evidence is/are needed.
Activity 3. Complete the description according to the charts, paying attention to subject-verb agreement.
Activity
FUTURE
Last week,we asked you to design your ideal planet for people on Earth to live on in the 22nd century. We have received over 500 entries and have been amazed by your imaginations! Here’s one of the designs.
Three quarters of the surface is made up of land,while the rest is sea,covering 25% of the surface.
Half of the land is covered with trees. Residential area and arable land both account for the same proportion,20% of the total land. The rest is desert, covering 10% of the total land.
There are three kinds of people. Fifty per cent of the people are original residents,30% are from Earth and 20% are from other planets.
Activity 5. Listen to the conversation and choose its main idea.
Activity
1　Time travel is dangerous.
2　Talking to people in the past can change the future.
3　Anything you say or do in the past can affect the future.
4　Time travel within your own lifetime should be avoided.

Activity 8. Read the passage and put the expressions in bold into the boxes.
Activity
Besides time travel, we have much to look forward to in the future, thanks to advances in technology. One area that is likely to change dramatically within our lifetimes is medical care. Although I wouldn’t bank on patients feeling confident about seeing a robot doctor any time soon, I’m sure that AI doctors are on the horizon. I think it’s also fair to say that we can get our hopes up when it comes to finding cures for serious diseases, such as cancer. I reckon that nanorobots that can eliminate cancerous cells are just around the corner. Some of these ideas may sound far ahead of their time, but I’m sure they’re bound to happen sooner or later!

Different attitudes towards Robutt
·Parents：
·Jimmy：
Now talk about your attitudes towards the story.
Jimmy already has a robot pet named Robutt. His parents think it would be good for Jimmy to have a real dog, and that he would like it. They want to send Robutt to another family. To his parents’ surprise, Jimmy refuses to accept the real dog, because he loves Robutt and he believes Robutt loves him too. For Jimmy, Robutt is not just a mechanical dog, but a real friend.
They think Robutt is a mechanical imitation of a real dog.
He loves Robutt and treats him like a real dog.
Jimmy’s parents get a dog from Earth. They want to give it to Jimmy as a pet. But...
Plot
Think & share
1 What are the similarities and differences between Robutt and a real dog
【Suggest Answer:
Similarities:
Both are able to respond to orders given by human beings.
Both can outrace human beings.
Both can guide and protect human beings.
Differences:
They have different appearances.
A real dog is a living creature,while Robutt is a machine.
A real dog loves human beings as a result of its nature,while Robutt is just adjusted to act as though it loves human beings.】
Think & share
2 Is there any foreshadowing of Jimmy’s final decision Find clues in the reading passage.
【Suggest Answer:
Yes, there is.
At the beginning of the story, we know Jimmy has never seen a real dog. It also seems that he spends a lot of time with Robutt. Jimmy plays with Robutt enthusiastically, shouting “Come on, Robutt.” In the middle of the passage, we are told that “Jimmy couldn’t go wrong while Robutt was around”, indicating that Robutt protects Jimmy well.】
Activity 4. Work in groups. Give a talk on whether it is possible to have a real friendship with a robot.
Activity
1 Answer the questions to help to form your point of view.
Why do Jimmy and his parents have different feelings towards Robutt
【Suggest Answer: Because Jimmy was born on the Moon, he has never seen a real dog. He has been getting along well with Robutt, and thus has developed an affection for him. He cannot figure out why a real dog is better than a mechanical dog,despite his father’s explanation. While Jimmy’s parents have seen real dogs before they left Earth. They know what real dogs look like. They think Robutt is just a machine.】
Activity 5. Read the story and answer the questions.
Activity
1 What happened to the prison and what was the cause
【Suggest Answer: There was a prison breakout, caused by faulty robotics.】
2 What kind of job do you think Carolyn has
【Suggest Answer: She might be a prison governor.】
【Sample】
Carolyn had a long commute to the prison, even by aircar. When she arrived, everything seemed normal, except for a robot lying at the front gate, motion-less. It’s an old model,she thought. They broke down now and again. She passed through the gate, noting that everything else was apparently in order.
But just as she closed her office door behind her, a loud alarm sounded. Carolyn’s blood froze. She had only ever heard that sound during drills. It can’t be! she thought. A general systems failure! She looked out of the reinforced glass of her office window into the prison below. Sure enough, the robots were out of control. Most had stopped moving at all. Some spun aimlessly around and around. But others were randomly operating things,including the cell gates,and she could see prisoners rushing out to freedom. “Grab the robots’ weapons and run!” shouted the prisoners.
Activity
【Sample】
Carolyn opened her bag and reached for her emerg-ency call device. Her heart sank as she realised she had left it at home. I need to call in the police, she thought. But how Without the device, she couldn’t communi-cate. Nothing in the prison would work properly now.
There was a voice behind her. “Looking for one of these ”
Carolyn gasped. “Julius!” There was her second-in-command, holding an emergency caller in his hand. “What are you doing in my office ”
“It should be my office!” snarled Julius. “I’ve work-ed here for forty years...and the City Commiss-ioners gave you the job as prison governor! But now you’ll pay. You’ll all pay! I can make every robot in every prison in the city go crazy. The prisoners will escape, and the city will burn!”
Activity
【Sample】
Then the door burst open,and the room was suddenly flooded with riot police. And there was...Todd!
“I took the aircar over here to bring you this,” he said quietly,winking as he pushed the emergency call device secretly into her hands. “I could see there was trouble, so I activated it to call in the police.”
“It was Julius,” said Carolyn,watching the police bundle Julius out of the door. “He’s gone mad.”
“Sure,” said Todd. “But now we know how easy it is to cause a mass robot breakdown. You’ll have to write a report. Make some recommendations to upgrade the robots.”
“I know.” Carolyn slid from Todd’s hug and walked towards the door. She could see the police rounding up the prisoners. “But right now, I’ve got a prison to run.”
