2 . A humanoid robot can transmit (传输) video and touch sensations to a person wearing special gloves and a virtual reality (VR) headset hundreds of kilometers away, offering a way for people to attend events without traveling.
The iCub3 robot is a 52-kilogram and 125-centimetre-tall robot with 54 points of articulation (关节点) across its body. Its head contains two cameras where a human’s eyes would be and an Internet-connected computer where the brain would go. Along with the cameras, sensors covering its body send data to the robot’s “brain”. These sensations are then copied on a suit and VR headset worn by a remote human operator.
When the operator reacts to what they see and feel, the suit’s sensors pick up the movements and the robot matches them. “The key is to translate every signal and bit of numeric data that can be sent through the network,” says Stefano Dafarra, who is part of the iCub 3 team. There can be a small delay of up to 100 milliseconds to collect and transmit the visual footage, but the operator can improve this by moving slightly slower than normal.
The team has demonstrated the robot at the Venice Biennale, where it wandered through an exhibition while its operator stood 290 kilometers away in Genoa.
Dafarra hopes people will use iCub 3 to attend events remotely, reducing the need to travel. “But at present, a fall could be hugely damaging to the robot, and it’s uncertain whether it could stand up again on its own,” he says.
“iCub 3 is an interesting robot and has clear advantages over the previous version,” says Jonathan Aitken, whose laboratory owns a prior version of the robot. However, he is disappointed that the team wasn’t clear in its research about the data transmission requirements of the new version of the robot. “It would be good to know just how much data was required, and what the upper and lower bounds were,” he says.
1. What is iCub 3 intended for?A.Breaking the distance limit. | B.Boosting virtual exhibitions. |
C.Popularizing travel destinations. | D.Reducing the harm of daily falls. |
A.iCub 3 hasn’t been demonstrated up to now. |
B.They should move faster to improve the accuracy. |
C.Its operator has to stand less than 100 kilometers away. |
D.They may not behave the same at exactly the same time. |
A.It is not perfect. | B.It seems hopeless. |
C.It is particularly flexible. | D.It has been widely received. |
A.Collect more data for transmission. | B.Make a newer version of the robot. |

3 . In-flight announcements can be crucial in providing important information.
Imagine boarding an aircraft late in the evening or during the early hours of the day, eager to get some sleep. After forcing yourself to stay awake for the safety briefing, you fall fast asleep.
Which announcements are necessary? There are many in-flight announcements that are absolutely necessary. Anything to do with safety and security is, of course, essential. Anything to do with delays and scheduling is also important to know.
However, anything beyond these is questionable. Of course, the additional announcements are meant to better connect passengers to the flight crew, the airline, and the overall experience of flying.
So from my point of view, in-flight announcements have gotten out of control and need to be controlled.
A.In-flight meal options? |
B.After all, they are rules that should be obeyed. |
C.Actually, most of the passengers are likely to feel sleepy. |
D.It’s not just passengers trying to sleep that are interrupted. |
E.It also seems polite to introduce those who will serve you. |
F.Suddenly, you’re in the air and something has stirred you awake. |
G.This might include delays, the local time at destination, and of course, emergencies. |
4 . I am an ecologist from Zimbabwe, but I’ve been based at the National University of Lesotho in Maseru for more than 13 years. Lesotho is a mountainous inland kingdom in southern Africa. Its high-altitude (高海拔的) wetlands support the Lesotho Highlands Water Project, which delivers water to the Vaal River System in South Africa, generating both income and electricity for Lesotho.
I study the ecological balance that keeps those areas functioning properly: The wetlands t rap water when it rains and release it gradually during dry periods. An important part of this is to map the plants, animals and general environmental conditions, and how they change over time.
One of our team projects monitors the soundscapes of those areas to identify the animals that live there. We put sensitive recording equipment in the field for weeks at a time. This is of great help because, although that site is just 180 kilometers from my university in the capital of Lesotho, it can take up to four hours to drive there.
The data we gather are huge, and although we do listen to the recordings, we mainly use software to help us analyze the data. We want to compare our recordings between seasons, between dawn and dusk (晨昏) and between day and night, to understand the rhythms of the ecosystem. We also compare our recordings from different wetland types. High-altitude areas are easier to be affected by climate change and, in my view, it is the greatest threat those protected wetlands face.
Listening to the recordings makes me happy because I enjoy hearing a variety of sounds, especially the singing of different birds. In a small country like Lesotho, there are so many knowledge gaps to fill — it’s one of the benefits of being a researcher there. I hope that in the future some of you in this classroom will contribute to this as well.

5 . Most of you may want your kids to stay away from social media because it can bring harm. But social media can have a positive effect on them, like helping them learn how to communicate with others, improve relationships and deal with somebody who isn’t being kind to them.
Talk to your kids. From the beginning, it’s important to have an open and honest conversation with your kids about what social media is and what it can be used for. Ask why they’re interested in having an account on a particular platform and what they want to use it for.
Limit screen time. The American Academy of Pediatrics (儿科) recommends limiting screen time to two hours a day for kids.
Monitor their usage.
A.Be a role model |
B.That’s a good guideline |
C.Check on what your kids are consuming |
D.Put a ban on improper social media behaviors |
E.As they start venturing into the world of social media, keep talking |
F.Parents should know how to interact with their kids on social media |
G.Therefore, no social media at all might not be the best solution for your kids |

In a small town located in the mountains, there was a young boy named Owen. He was crazy about basketball more than anything else in the world. He would spend hours every day practicing his dribbling (运球), shooting and passing. He dreamed of one day winning games on a team.
Owen’s town had a small basketball court that was often empty. Owen would go there every day after school to practice. One day, as he was shooting hoops (投篮), he heard a voice behind him, “Hey, kid! You’re pretty good!”
Owen turned around to see a tall man with a friendly smile. The man introduced himself as Coach Johnson and asked Owen if he wanted to join his basketball team. The team was made up of kids from all over the town, and they practiced every day after school.
Owen was overjoyed because he had never played on a team before. He wanted to start and win games. Owen quickly became the star player of the team.
However, the team never won a game. “I had trained so hard and performed excellently, but we were always losing! Jack should have run much faster towards me and Kris should have passed the ball to me!” Owen kept complaining to the coach.
The complaint seemed understandable! Owen was admired by his teammates because he was fast and had incredible shots. However, Johnson knew Owen lacked something important. He told Owen to learn to play with his teammates as a team instead of just focusing on himself. Owen didn’t quite understand that at first and insisted he just needed to practice harder to win games.
However, disaster struck. Owen injured his ankle one day and had to sit out for several weeks, which let him fall into anxiety. He felt his dream was slipping away.
During his recovery at home, Owen refused to see anyone on the team, except his coach. Johnson handed Owen a phone downloaded with some videos about the best basketball teams and some cards from Owen’s teammates.
