However, the1 opportunities and resources there made it difficult to pursue my own growth, so I went to the United States for my Ph. D. and postdoc. I assumed success meant2 a position at a highly research-related institution.

But during my postdoc, I realized I needed to change my3. I am a father of two daughters, one of whom requires long-term medical care. My modest4 and limited benefits brought me financial instability and emotional5. Professional stress bled into my home life. In turn, the weight of my personal6 made professional setbacks more disastrous. Trapped in this7, I began to reconsider my career path.

I applied to several positions, and was delighted when I started to receive invitations to interview. The campus visits included teaching8, discussions about mentoring, and an emphasis on how I would9 research into a student-centered environment. Such requirements were10 but refreshing, helping confirm that I was heading in the right direction. The students' engagement and curiosity11 my passion for mentorship. And research didn't disappear — perspectives on it12.

I've learned to redefine13 after 2 years into my current position. It isn't14 about high-impact publications or grants (拨款). It's about asking meaningful research questions,15 opportunities for students to grow, and maintaining a balance between professional ambitions and personal well-being.

You should always remember you are not a teacher. Although you need to guarantee that your children are completing their homework without any mistakes, you shouldn't do the homework for them. If you do, your children won't be able to address their own issues and will always depend on others for help.

Besides, be cautious about rewarding children for good grades. If you abuse this, your children will only attempt to study for a reward. Getting bad grades, they'll feel like a failure. Thus, it's better to praise your children when they pass a test. This way, they'll see their mistakes as opportunities to improve and not see themselves as failures.

If you only spare no efforts to force your children to study, both you and they will be frustrated. Therefore, place emphasis on devoting time to other activities that are fundamental to your children's development, like playing sports and watching movies.

Some parents hold the belief that mental disorders lead to children's lack of interest in study. It's very likely that their children are simply demotivated or disinterested. Therefore, it's good to take the above tips into account. As a result, your children may find a genuine desire to study and do their own homework.

A. That's not necessarily the case.

B. It is teachers' duty to correct homework mistakes.

C. You may enroll them in various after-class courses.

D. If not, patiently show them how to do better next time.

E. Instead, offer them guidance and tools to do self-research.

F. Vital as study is, it's not the only thing kids must focus on.

G. Even if they fail in exams, you'd better control your temper.

It suggests that individuals act based on the meanings they attach to objects, people, and situations. These meanings, in turn, are constructed and improved through social interactions. Symbols, such as language, gestures, and objects, are central to this process, as they provide the medium through which individuals understand and interpret the social world.

A symbol, in the context of symbolic interactionism, is anything that carries meaning beyond its literal form. It could be a word, gesture, object, or even a social role. Symbols are not naturally meaningful; rather, their meanings are socially constructed and learned through interaction. For example, a handshake is not just a physical act but a symbol of greeting, agreement, or friendship in many cultures. Compared with saying hello, shaking hands has more unexpected effects.

Symbols are essential for human communication and interaction. They allow individuals to convey complex ideas, emotions, and intentions in a way that is understood by others. Language, for instance, is a system of symbols that allows people to communicate abstract concepts like love, justice, and freedom. Without symbols, human interaction would be limited to immediate, visible experiences.

One of the most important ways symbols function in social interaction is through the construction of identity. Individuals employ symbols to express who they are and how they relate to the world around them. The clothes one wears are symbols, which signal one's profession, social status, or even personal beliefs and preferences. For example, a doctor's white coat symbolizes medical authority, while a business suit might symbolize professionalism.

So have you got the magic of symbols?

Flooding can be difficult to accurately predict, particularly riverine floods, due to a lack of resources and data related to flood history, water levels, and terrain (地形). AI use in weather forecasting is nothing new. Still, the rise of more powerful processors and larger data sets is allowing for new scales of prediction, including a new Nvidia digital Earth.

A small percentage of global rivers have streamflow gauges (测量仪) which can be used to warn people if the volume of water flowing through the river changes. When combined with other points such as the local terrain, settlements near the river, weather forecasting, and historical events on the same river, data can be used to predict flooding. Google researchers gathered as much global data as they could access and trained new AI models to analyze them. Afterwards, those models could then make predictions for those regions where data might be considerably limited or even nonexistent.

The team launched a Flood Hub platform, which provided access to forecasts in 20countries where flood forecasting had been difficult in the past. The platform collected seemingly unrelated information which was available locally, fed it into the AI system as a reminder, and ordered the AI to fill in the gaps and then classify data. So far Flood Hub has been expanded to 80 countries in Africa, Asia-Pacific, Europea, and the Americas, covering over 460 million people globally, particularly those in communities suffering from flooding. "Where possible, we also provide forecasts in Google Search and Google Maps and via Android warnings." the Google team declared.

The story dates back to the times when I was in kindergarten, which has classical music CDs to offer parents. Thinking that it wouldn't be a bad idea to get me some music to listen to, my parents ordered them without any ambition of developing an interest in classical music or whatsoever. Without knowing who Bach, Vivaldi and Chopin were or what to expect, I just played the CDs one after one and grew increasingly fond of them.

What took place meanwhile was my piano studies, which again exposed me to classical music. But I have to admit the beginner pieces sounded rather uninspired and dull to me. Thanks to YouTube, I was able to explore more than what my first piano teacher offered — from piano to orchestral music, from Bach to Scriabin. Very often, I didn't practise the pieces my teacher assigned, but the pieces I truly loved! It's also through the Internet that I discovered one of my piano idols later, Grigory Sokolov. Later on, I became interested in not only the music itself, but also composers and music history.

I still remember in a 28-day outdoor program in Australia organized by my high school, we weren't allowed to use our mobile phones and there wasn't any piano either. What I could only do was to repeatedly recall Chopin's Preludes (前奏曲) Op. 28 when walking up the hills. I felt peaceful as usual, but even happier with growing enthusiasm for music.

To me, classical music explores the deepest emotions of humanity but can be so humorous as well. The magic of it lies in its ability to cast light on aspects of human conditions and, at the same time, to go beyond the reality.
