China Aerospace Science and Technology Corp, the nation’s leading space contractor, said in     2     press conference that the rocket blasted off at 12:43 p.m. from the Xichang Satellite Launch Centre in southwestern China’s Sichuan Province and later deployed the Shiyan 10-02 experimental satellite into its orbit.

The satellite     3    (task) with demonstrating new technologies     4     would be used for monitoring the environment in space and other purposes.

7 . Artificial intelligence models can trick each other into disobeying their creators and providing banned instructions for making drugs, or even building a bomb, suggesting that preventing such AI “jailbreaks” is more difficult than it seems.

Many publicly available large language models (LLMs), such as ChatGPT, have hard-coded rules that aim to prevent them from exhibiting racial or sexual discrimination, or answering questions with illegal or problematic answers — things they have learned from humans via training data. But that hasn’t stopped people from finding carefully designed instructions that block these protections, known as “jailbreaks”, making AI models disobey the rules.

Now, Arush Tagade at Leap Laboratories and his co-workers have found a process of jailbreaks. They found that they could simply instruct one LLM to convince other models to adopt a persona (角色), which is able to answer questions the base model has been programmed to refuse. This process is called “persona modulation (调节)”.

Tagade says this approach works because much of the training data consumed by large models comes from online conversations, and the models learn to act in certain ways in response to different inputs. By having the right conversation with a model, it is possible to make it adopt a particular persona, causing it to act differently.

There is also an idea in AI circles, one yet to be proven, that creating lots of rules for an AI to prevent it displaying unwanted behaviour can accidentally create a blueprint for a model to act that way. This potentially leaves the AI easy to be tricked into taking on an evil persona. “If you’re forcing your model to be good persona, it somewhat understands what a bad persona is,” says Tagade.

Yinzhen Li at Imperial College London says it is worrying how current models can be misused, but developers need to weigh such risks with the potential benefits of LLMs. “Like drugs, they also have side effects that need to be controlled,” she says.

8 . The Benefits of After-school Activities

Your kid is asking for piano lessons, joining a soccer team or taking ballet classes, but you’re not so sure that your money will be well spent.     1     , read these next benefits of participating in hobbies outside the home. It might just convince you to book the first class.

From arts and poem writing to music and crafts, there are lots of creative after-school activities available out there for kids of all ages. Not only do these classes stimulate your little one’s imagination, but they also encourage curiosity.     2     . Interacting with others, sharing, cooperating and solving conflicts are all added bonuses and they are all extremely helpful tools in building self-confidence.

These days, the fast-paced world we live in causes stress to us all, including children — and providing fun environments and spaces where they can feel safe and creative is an excellent idea to help your child reduce the stress.    4     . You have to aim to eliminate the stressors in your child’s life, regardless of the type of stress your child is dealing with, be it the case of shyness, social anxiety or pressure from school or home life.

Avoiding childhood obesity has become a real issue in a world where kids spend more and more time indoors, glued to screens. But if your child shows any interest in a sport (even if just by watching it on their iPad), grab the opportunity and introduce after-school activities that focus on said physical activity. In these activities, your kids can also learn important lessons like respecting others and teamwork.     5     .

9 . How to Speak English Fluently

Immerse(沉浸)yourself in English every day

    1    The best way to quickly improve your English is to spend at least a few minutes practicing every day.

There’s a special language learning method called “immersion”. With immersion, you try to surround yourself with the language as much as you can in your day-to-day activities.

Accept that English grammar has a lot of exceptions

Sometimes, you can find patterns in English grammar, but other times English doesn’t make sense at all. It’s easy to get stuck on learning how to speak English properly if you try to find a reason for everything.     2    So the best thing to do is just memorize the strange exceptions and move on.

Learn intonation, body language and gestures

Intonation is the “rise and fall” or tone changes in how a person speaks. Body language is how a person uses their own body to support (or go against) what they mean. Gestures are hand and body movements that work together with what someone is saying.     3     One way to learn is to just watch how native English speakers communicate with each other.

Share your opinions online

To really learn English speaking, you need to learn how to express yourself in English. Even if you have ideas for conversations, it can be hard to know how to put them into your own words. You can practice this by participating in conversations online.     4    

Get direct feedback

To improve your speaking, you can ask directly for feedback. Since you usually can’t do this with casual conversations, it might be worth setting up a language exchange, where you can ask the person to tell you directly if any of your sentences sounds awkward or unnatural.     5    Hello Talk also allows you to chat in English, and then your conversation partner will literally mark out your mistakes.
