A
Many of you may have the experience: you get on a train and are ready to have a sleep or read a book. Then you find that the person in front of you is watching a film on his mobile phone loudly. And the person behind you is talking on her phone during the trip.
You wish the train could be less noisy. There is a solution for you. The Beijing-Shanghai High-speed Railway has quiet carriages(车厢) now.
In quiet carriages, the videos have no sound. Doors are closed to make the noise from other carriages less. Train attendants(列车员) make sure that people follow the rules and keep quiet.
If people would like to follow the rules, they can choose quiet carriages when they book their train tickets. The ticket prices are the same as those for non-quiet carriages.
Some people say that all carriages should have this kind of quiet environment. Though some internet users like the new service, they also have some questions, such as "How quiet should travellers be in quiet carriages?"and "Can we talk to our friends if we need to?" After all, quiet carriages give people better service. They may become popular across the country in the future.

Are you troubled by housework like cleaning tables or tidying your room? A new robot is here to help! 1, a group of engineers from Stanford University and Google's DeepMind have created a smart robot—Mobile ALOHA. It can carry out many kinds of work around your house.
In the videos posted, we can see the robot can be 2 to carry out a large number of tasks, from cutting vegetables to cracking(破开) eggs. It's also good at watering plants, petting cats, cleaning the floor, washing clothes, etc.

The robot isn't perfect. It can move chairs 3 80 per cent of the time. But for cooking dishes, it's only 40 per cent. In short, it's far from perfect.
In fact, AI robots are good at tasks, 4 maths and playing chess, but they face challenges(挑战) when it comes to simpler actions like cleaning. And it's the same for Mobile ALOHA. For example, if its body doesn't move correctly—even just with a small deviation(偏差), its arm may move too far to 5 the grass.
"Robots are not ready to take over the world," the team posted on a social platform.
