More people are increasingly biking to commute (上下班往返), for exercise, or just for fun. Bicyclists should observe bicycle safety rules to help reduce deaths and injuries on the road.
Wear a helmets
Every bike ride begins with putting on a helmet. Your helmet can best protect you. For the most comprehensive list of helmet sizes according to manufacturers, click here to visit the Bicycle Helmet Safety Institute (BHSI) website.
Avoid crashes
There are two main types of crashes: the most common (falls) , and the most serious (the ones with cars). Regardless of the reasons for the crash, prevention is the key point.
Be alert (警惕的)
Be alert to the road and all traffic around you; anticipate what others may do before they do it. This is defensive driving — the quicker you notice a potential conflict the quicker you can act to avoid a potential crash.
Pay attention to road signs and road conditions
Obey street signs, signals, and road markings, just like a car. Look ahead for risks or situations to avoid what may cause you to fall, like potholes (坑洼) and train tracks. No texting, listening to music or using anything that distracts you by taking your eyes and ears or your mind off the road and traffic.
Ride in the same direction as traffic
This way, if the sidewalk ends, you are already riding with the flow of traffic. If crossing a street, motorists will look left, right, left for traffic. When you are to the driver's left, the driver is more likely to see you. Slow and look for traffic (left — right — left and behind) when crossing a street from a sidewalk; be prepared to stop and follow the pedestrian signals.
I'm Bob Sassone. I'm typing the first draft of this letter on a 1954 Smith Corona Silent, a green and gray beauty. Now, for most of us, buying a typewriter in this age of the Internet, texting and tablet computers is odd enough. But there are plenty of writers who still use typewriters. Using a typewriter is a form of time travel. For people who know me well, the fact that I use a typewriter isn't a surprise. I'm someone who still has a landline and wears a wristwatch. So owning a typewriter fits into that life quite nicely.
Why do I love it so much? It is made for doing one thing: Writing. There are no distractions no email to check, no alerts that grab your attention. Some people look at it and said, "But you can't access the Internet on it!" Not being able to access the Internet on my writing machine is a feature, not a bug.
Of course I don't use a typewriter all the time. It's impossible in the 21st century. As someone who does a lot of work online and has to email his work to editors and other people, doing all of my writing on a typewriter just isn't something that would work today. And after using a computer keyboard for over 30 years, typing on a typewriter is hard. But it's wonderful to write letters, create first drafts, make notes and lists, and a typed message on a card or thank-you note looks fantastic. I didn't buy it for show. I'm actually using it!
So I write on both a typewriter and a laptop. I live in 1954 and in the modern digital age. Old and new, analog and digital, beauty and convenience. I straddle both worlds and try to use the technology that suits me best and works the best depending on what I'm doing. And that's really what we all should be doing with technology, isn't it?
Is there any such thing as a salt tooth? We are familiar with a sweet tooth, along with the negative effects of sugar. We are broadly aware of the disadvantages of too much salt, including high blood pressure, which puts pressure on the blood vessels (血管), the heart and the kidneys. It can also lead to water retention (水肿). But we don't tend to police how much salt we eat — at least, not as rigorously as with sugar — or question whether we are just paying attention to our bodies, which require some salt for muscles to work properly, or we are being controlled by a strong urge.
A salt tooth is quite unlike a sweet tooth. It doesn't create an appetite for itself at the hormone level. But salt does make our taste buds (味蕾) get used to it, so that the more you eat, the more you need to get the same salty hit. This is why chefs can get heavy-handed with it.
As Sam Bloom, a nutritional therapist, explains, "What is generally more concerning is the fat that is used together with salt, like salty crisps, fries and fast food. Ready meals are often the worst for hidden salts. Anything that adds flavor that isn't a spice or herb will probably have salt added to it and can make you want to eat more because it tastes good. The salt and fat combination in these foods is what causes problems with cholesterol (胆固醇). The salt that people add to a meal is much less concerning."
Nutritionists' suggestion is convincing: When the desire for salt hits, avoid going straight for salty snack foods such as crisps and instead ensure you are well hydrated. Seek out whole foods, such as olives and leafy greens. These foods will help you alleviate the desire for salt, which may often be due to a desire for nutrient-rich food.
Italian diver and gardener Sergio Gamberini decided to see if he could grow vegetables in a plastic balloon underwater. The experiment was a success—so he decided to dive deeper into the world of underwater agriculture.
Today, Gamberini is the founder of a company using "biospheres" off the coast of Italy to grow a variety of plants, introducing the world to a new type of agriculture. The company's six "biospheres" are air-filled plastic balloons about two meters wide. Each is fixed to the seabed by chains so that it sits between 15and 36 feet below sea level. The biospheres are equipped with cameras and sensors that allow researchers in the company to monitor CO2levels, humidity, temperature, and more from a control tower on the shoreline. There's also a device to communicate with divers in the biospheres.
Solar panels (太阳能电池板) on the roof of the control tower power the fans that create airflow inside the biospheres, and because the temperature inside and outside the biospheres is consistent, there's no need to expend energy on the heating or cooling systems needed for traditional greenhouses.
The underwater garden doesn't require pesticides (杀虫剂) since bugs can't reach the plants, and though more research is needed, the company notes on its website that the higher-pressure conditions underwater appear to help plants grow more quickly.
The company is now ready to shift from the research phase of development to optimizing (优化) its biospheres for industrialization, with the goal of expanding them off coastlines around the world. To achieve the aim, the startup is now taking advantage of "digital twin" technology to precisely simulate (模仿) every aspect of its underwater garden.
Even with all the optimization potential offered by technology, Gamberini admits it's hard to imagine the produce grown in his startup's biospheres ever competing financially with traditionally grown crops. Still, he hopes the system's sustainability will be enough to draw customers.

For me, one of the most fascinating aspects of exploring diverse cultures is observing how ordinary and sometimes even insignificant things can 1 from place to place. The coffee culture is a great example. I love sharing with people how Shanghai is a perfect 2 for me for many reasons, and coffee is one of them.
After I returned to China in September 2022 to study at Shanghai Jiao Tong University, I soon developed a(n) 3 with two other international students. During the lunch break, we would have a cup of coffee at the campus cafe every day. What we 4 was that people did not work during that coffee break; instead, they 5 savored (享受) their conversations over coffee. So, for us too, it felt wrong to continue our studies at the coffee shop and thereby disrupt the 6 .
Perhaps drawn by this 7 energy, more students joined us day by day, and our group of three became a big party. Coffee 8 us as we greeted newcomers and got familiar with other local students. I feel this is how the coffee culture 9 here — to make people a little bit happier, and to 10 you up when you feel cold.
That's why I always prefer to get my coffee 11 instead of ordering online — for the sake of 12 the general mood of the place. It is not something 13 ; it's a feeling in the air that makes you want to come, 14 it in, and be nourished by the good energy. It's like an upbeat song from your childhood — once you 15 it, you start smiling.
People associate deafness, blindness, and other disabilities as weaknesses but that is not often the case, it (certain) wasn't the case for the famous American author Helen Keller. When she was a child, she was described a "Monster" by her family members. That was because of her bad habits, temper tantrums, and she behaved. However, all of that changed within a year and she transformed fully. She became one of the (great) inspirations that the world has ever seen. She didn't just change (she) but she changed others.
Helen Keller was born on June 27th, 1880, in Tuscumbia, Alabama, America. She was born normal, with normal sight and hearing abilities. All was good until Helen submitted to a rare disease, the doctors referred to as "Scarlet Fever". She recovered from disease but at the cost of her sight and hearing abilities.
This did not stop her from pursuing the amazing (accomplish) she would achieve. Her teacher, Anne Sullivan helped her and made her get the ability (communicate) properly. Helen graduated from college in 1904 and was the recipient of many awards and honors. She became one of the best humanitarians the world has seen, along with (become) the founder of the American Civil Liberties Union (ACLU).
Running has always been a big part of my life. It was an easy and cheap way to stay healthy when I was a teenager and at university. As I got older, I kept running though I took on the responsibilities of being a mom, having a job and other hobbies. Running was a fun activity that I could do quickly and then get back to my busy day.
When I moved to a new city, I was excited about trying new foods, visiting new places, meeting new people and having new experiences. But, I also felt lonely and really wanted to make new friends. I joined a book club and a dinner group. But after a few months, I still felt like I hadn't made any close friends.
One day, someone asked me if I wanted to run in a half marathon. Without thinking, I said, "Sure, count me in!" A half marathon is 13.1 miles, which is a lot longer than the three miles I usually ran. I was a bit scared, but also excited.
After the shock wore off, I started to learn everything about running a half marathon. I even bought my first pair of really good running shoes. They were the most expensive shoes I'd ever owned. I was ready to start training with them.
My new running friends picked me up at my house, and we started to jog together. I took it slow at first, running one mile, then two. They taught me how to run properly and how to drink enough water. I learned new words like chafing, carb loading, strides, and electrolytes. I slowly built up to running three, four and five miles. Running seven miles straight felt like climbing a really high mountain, and I started to love the feeling I got after a long run.
