Air Travel Guidelines for Children
We're here to help you prepare to fly with your children. Here's how it works.
Booking a child's ticket
You'll need to buy a separate ticket if:
· You book an international flight.
· Your child is 2 years old or older at takeoff.
· Your child is a baby sitting in his or her own seat.
In some cases, children can fly for free. If everything below is true, you won't need to buy your child a separate ticket:
· You book a domestic（国内） flight.
· Your child is a baby（less than 2 years old）, at takeoff.
· Your baby sits on the legs of a traveler over the age of 12.
· No more than 1 baby is seated on the legs of a traveler.
Now for the rules, each traveler over the age of 12 may accompany（陪伴） up to 2 babies, each seated in their own seat.
Documents a child will need
The airlines determine what documents you'll need to travel. In short, if you're flying domestically, each child might need a photo ID. If you're flying intemationally, each child will need a passport. Additionally, children under 18 traveling to Mexico need to provide proved documentation and letters of permission. For more information, please visit the US Embassy（大使馆） website.
Unaccompanied children on flights
· Some airlines may charge a fee for unaccompanied child service.
· Children under 5 and over 17 might be unfit for unaccompanied child service.
· Both the adult dropping the child off at the airport and the adult picking the child up are required to show identification.
Contact your airline to ask about more information.
Fifteen years ago, I loved going to the gym, but family life and work commitments meant I was finding it hard to get there. With the help of my dad and uncle, I built my own gym in the garden. It's basically a beautified room with insulation（隔热层） and electries and a small heater for the winter. We built a comer desk too intending it to be for me to do the paperwork for my small business. However, the desk served its real purpose when I started my writing journey two years ago.
I've always had stories going through my mind. I could be out jogging and I'd lose myself playing out thoughts in my head like movie scenes. Once seen, they stay in there. I have trouble keeping other information, but when it comes to story ideas, they lock in. I have many full novel ideas in my head waiting to be written. When I was younger, I wasn't brave enough to write. I didn't do well in school and I've spent most of my life in physical work, so the idea of becoming a writer felt laughable.
I now know there isn't a writer type; writers come in all forms. I still use the gym for its real purpose, but some of the equipment has been replaced by books and a small bed for the time when I want to relax and read. I like to have my desk looking colorful-some might say messy. My love for sport is clear to see, with photos around of my favorite boxers and the football team I follow. On the other hand, having my own writing room is important. Without it I wouldn't be where I am now on my writing jourmey. It's far from charming, but it is mine. It's my happy place.
I've spent much of my life dealing with written and spoken words. Now I'm a technologist making use of natural language processing for human good. Given that I work in artificial intelligence（AI）, I'm realizing something dangerous happening. Machines are ruining the way we communicate.
AI voices are normalized and yet cold, no matter which accent（口音）you set your Siri or Amazon Alexa into. It's difficult to normalize language to be inoffensive because sometimes we do make people feel uncomfortable or even make them annoyed. Yet this is exactly what we're asking artificial intelligence to do for us on a billion-person scale. Once these rules are carried out by machines, they're unavoidable and create much bigger issues.
We notice that there is an active desire to only include standardized language in AI-powered tools in an attempt to avoid including potentially hateful or offensive language. And these AI-powered tools are exactly what we use to complete our thoughts almost at any given time. They are everywhere—in our emails, word processors, and web pages. The machines are pushing us into a common tongue, and we accept it as a matter of convenience. But what's the cost? We're trading uniqueness and accuracy for convenience. We're also handing the power of acceptable speech to machines not people.
In the real world, people don't communicate like a Wikipedia（维基百科） article. We use tone（语气）, humor and facial expressions. We can tell where peoplewere bon based on their accents and wording. Humans are truly unique, and our communication is constantly changing. So we should demand AI systems that promote individuality and uniqueness. We should demand to know how AI is developed and the data used to build it. Because we all deserve this.
"A beautiful field of flowers can be a rather noisy place. It's just that we can't hear the sounds."Scientists at Tel Aviv University have conducted a six-year experiment, proving that plants make noise in certain stressful situations.
Plants produce a high frequency（频率） clicking sound, and when short of water, or damaged, the clicks become far more regular. They also made different sounds, depending on whether they were thirsty or injured. "Each plant and each type of stress is related to a specific sound,"said Professor Lilach Hadany, who led the research study.
Focusing particularly on tomatoes, wheat and corn, the plants were placed in a soundproof（隔音的）room and recorded by microphones. Some plants were starved of water, others cut, and a control group was left undamaged. The researchers used an algorithm（算法）to separate the noises, suecessfully telling the difference between the sounds depending on whether they were dry or cut. The algorithm did this in a greenhouse setting which included far more surrounding sounds, but it was still able to recognize the particular cries for help of the plants.
On average, the human ear can hear sounds up to around 20kHz, while the sounds produced by plants are in the 40-80kHz region, far beyond our hearing. "The sounds made by plants can't be heard by humans but can probably be heard by various animals, such as bats, mice and insects," Hadany tells us. Though this has yet to be proven, it's possible that these creatures use this information to choose which plants to eat.
A study led by Reda Hassanien of China Agriculural University in Beijing years ago, also proved that plants reacted to sound waves, with some plants greatly increasing their yield. While evidence shows that plants can react to sounds, there's no evidence today that they can actually hear them.
How to Celebrate Earth Day
Are you looking for ways to celebrate Earth Day on April ? You've come to the right place. If you're ready to learn more about joining the global celebration, making real change, and doing your part to save our planet, read on!
Walk or ride your bike. Even one day can make a difference, but if you can commit（承诺） to walking or biking more often in the future, that's even better! If your daily commute（通勤）is too far for walking/biking, try public transportation like buses or trains.
Plant a tree. This simple act will benefit the environment for decades. Planting a tree only takes a few minutes, but it can make a huge impact. They help to save energy, clean pollution, and provide homes for many birds, insects, and other local wildlife.
Attend a local Earth Day event. If your community doesn't have one planned, consider starting one yourself. It's the perfect day to get together for a fun and educational celebration of the earth.
Visit a local farmer's market. Eating locally grown food is much better for the environment. For example, locally-grown food doesn't have to be transported long distances to end up on grocery store shelves.
Commit to one green act per day. You can keep reducing your carbon（碳） footprint once Earth Day is over. While small changes at the individual level may not seem like a big deal, they add up over time and can have a major impact. Moving forward, make it your goal to do one small thing every day to support the environment.
A. Earth Day can be every day!
B. Trees are extremely important.
C. Treas need extra care to grow well.
D. Get out there and appreciate our beautiful world.
E. Going car-free for the day will reduce harmful gases.
F. See if your community is holding an environmental fair.
G. You'll also be giving back to your community by supporting local farmers.

Summer was approaching, and Sarah and David had been eagerly looking forward to their visit to their grandpa's countryside home. They had always enjoyed their time with their grandpa, who had a kind and generous heart. His wooden house was surrounded by beautiful greenery, and the fields of flowers that spread beyond the house were breathtaking. As they packed their bags for the trip, Sarah and David could hardly control their excitement. They talked about all the activities they could do with grandpa, like playing board games and taking long walks in the countryside.
Finally, the day arrived, and the family set out on their journey to grandpa's house. The journey was a long and tiring one, but Sarah and David were too excited to feel tired. As they drew closer to their destination, they chatted even more excitedly about all the fun things they wanted to do with grandpa.
As they approached grandpa's house, he came out to greet them with a huge smile on his face. Sarah and David were overjoyed to see him and hugged him tightly. It was great to be back in grandpa's arms, and they felt the warmth and love from him.
However, shortly after they entered the house, they noticed that grandpa was not his usual self, looking pale and tired. Sarah and David felt a pang of sadness and worry in their hearts. Grandpa was not well, and they didn't know how to make him feel better.
As they sat with grandpa, trying to make him feel comfortable, Sarah remembered that grandpa loved gardening. She suggested that they could create a garden for him, which would be a lovely surprise. David was excited with the idea and immediately set to work gathering the necessary tools. They wanted to do something special for their grandpa and hoped that this would cheer him up.
