E-Bike Safety Tips
Before you go on your next two-wheeled adventure, make sure you’re familiar with the ins and outs of bicycle safety. E-bike is a great way to get around, save money and protect the environment. But fun as e-bikes are to ride, they still require practices to ensure your fun rides can be safe. It is important to pay careful attention to some tips.
Keep dos and don’ts in mind.
Wear a helmet. A full face helmet with a face shield can give you all around protection. Ride with the flow of traffic rather than against it. Don’t talk on the phone, text, or listen to music. Don’t forget to use the lights to make you more visible at night, which may decrease chances of road accidents.
That starts with checking that the tires are inflated (充气). Make sure the brakes are working properly. Take it for adjustment before you go for a ride if the bicycle hasn’t been used for a while. For an e-bike, also make sure your battery is charged. Plus, before and after every ride, inspect your bicycle for damage.
This is important for e-bike riders. With the ability to go faster comes the responsibility to know when you should slow down.
Read the signals and pay attention to the lane (车道) markings when you’re riding in the street. Moreover, check the sign to see where e-bikes are allowed. Riding on sidewalks or other walkways can lead to a fine. You can check the People for Bikes website (people forbikes. org) for more information.

Social media is one of the fastest-growing industries in the world today. A study carried out by the PewResearch Center showed that 92% of teenagers go online daily. The wide use of social media has changed nearly all parts of teenagers’ lives.
High school student Elly Cooper from Illinois said social media often reduces face-to-face communication. “It makes in-person relationships harder because people give attention to their phones instead of persons,” Cooper said. Yet, some people believe social media has made it easier to start relationships with anyone from anywhere.
The rise of social media has changed the way teenagers see themselves. The 19-year-old Essena O’Neill announced on the social networking service Instagram that she had stopped using social media. She thought she had gotten lost in appearing perfect online. Negative comments can also do damage to a teenager’s self-esteem (自尊). Teenagers who get negative comments can’t help but feel hurt. In particular, some social media apps such as Yik Yak may provide opportunities for cyber bullying (网络欺凌).
However, Armin Korsos, a student from Illinois, takes advantage of the comments he receives over social media to improve his videos on the social networking site YouTube. “Social media can help people show themselves and their talents to the world in a way that was never possible before,” Korsos said.
But Korsos realizes that social media has become a distraction (让人分心的事). “Social media is not all necessary, though it helps people connect with their friends and know each other well anytime.”

5 . Automation is a widespread term. Nearly everyone agrees that people will be working less once automatic machinery came in. For optimists, this is a promise of liberation: At last humanity would be freed from constant toil, and we could all devote our days to more refined pursuits. But others see a threat: Millions of people would be thrown out of work, and desperate masses would roam the streets. Looking back from 50 years hence, the controversy over automation seemed a quaint and curious episode. The dispute is never resolved.
A. J. Hayes, a leader (and no relation to me), wrote in 1964: Automation is not just a new kind of mechanization but a revolutionary force capable of overturning our social order. Whereas mechanization made workers more efficient—and thus more valuable—automation threatens to make them superfluous (过剩的)—and thus without value. The opinions I have cited here represent extreme positions, and there are also many milder views. But I think it’s fair to say that most early students of automation, including both critics and enthusiasts, believe the new technology would lead us into a world where people worked much less.
As for economic consequences, worries about unemployment have certainly not gone away—not with job losses in the current recession approaching 2 million workers in our country alone. But recent job losses are commonly attributed to causes other than automation, such as competition from overseas or a roller-coaster financial system. In any case, the vision of a world where machines do all the work and people stand idly by has simply not come to pass.
The spread of automation outside of the factory has altered its social and economic impact in some curious ways. In many cases, the net effect of automation is not that machines are doing work that people used to do. Instead we’ve dispensed with the people who used to be paid to run the machines, and we’ve learned to run them ourselves. These trends contradict almost all the expectations of early writers on automation, both optimists and pessimists. So far, automation has neither liberated us from the need to work nor deprived us of the opportunity to work. Instead, we’re working more than ever.
What about trades closer to my own vital interests? Will science be automated? Technology already has a central role in many areas of research; for example, genome sequences could not be read by traditional lab-bench methods. Replacing the scientist will presumably be a little harder than replacing the lab technician, but when a machine exhibits enough curiosity and tenacity, I think we’ll just have to welcome it as a companion in zealous research. And if the scientist is elbowed aside by an automaton, then surely the science writer can’t hold out either. I’m ready for my 15-hour workweek.

8 . Technology seems to discourage slow, immersive reading. Reading on a screen tires your eyes and makes it harder for you to keep your place. Online writing tends to be more skimmable and list-like than print. The cognitive neuroscientist Mary Walt argued recently that this “new norm” of skim reading is producing “an invisible, game -changing transformation” in how readers process words. The neuronal circuit that sustains the brain’s capacity to read now favors the rapid absorption of information.
We shouldn’t overplay this danger. All readers skim. From about the age of nine, our eyes start to bounce around the page, reading only about a quarter of the words properly, and filling in the gaps by inference. Nor is there anything new in these fears about declining attention spans. So far, the anxieties have proved to be false alarms. “Quite a few critics have been worried about attention spans lately and see very short stories as signs of cultural decline,” the American author Selvin Brown wrote. “No one ever said that poems were evidence of short attention spans.”
And yet the Internet has certainly changed the way we read. For a start, it means that there is more to read, because more people than ever are writing. And digital writing is meant for rapid release and response. This mode of writing and reading can be interactive and fun. But often it treats other people’s words as something to be quickly harvested as fodder (素材) to say something else. Everyone talks over the top of everyone else, desperate to be heard.
Perhaps we should slow down. Reading is constantly promoted as a social good and source of personal achievement. But this advocacy often emphasizes “enthusiastic” “passionate” or “eager” reading, none of which adjectives suggest slow, quiet absorption. To a slow reader, a piece of writing can only be fully understood by immersing oneself in the words and their slow comprehension of a line of thought.
The human need for this kind of deep reading is too tenacious for any new technology to destroy. We often assume that technological change can’t be stopped and happens in one direction, so that older media like “dead-tree” books are kicked out by newer, more virtual forms. In practice, older technologies can coexist with new ones. The Kindle has not killed off the printed book any more than the car killed off the bicycle. We still want to enjoy slowly. formed ideas and carefully-chosen words. Even in a fast-moving age, there is time for slow reading.

9 . Time and time again, I hear someone ask why anyone would want to keep an “ugly” building or a building that is dirty and clearly in need of work. I think you could say we preservationists look at buildings through a different angle — an angle that can see the swan (天鹅) in the ugly duck, the story in the simple lines, the book behind the cover.
Take the Queen Emma Building for example. While people may remember that building being named as one of the ugliest buildings in town, the angle from which a preservationist will view the building is that it is uniquely constructed with an artistical brise-soleil to block the sun. The designer used standard concrete bricks to form a decorative wall. Unfortunately, the brise-soleil was removed in 2011, making the building look like many of the contemporary buildings in town.
Sometimes people remember a beautiful site that was replaced by a “horrid” piece of architecture and can’t get over their anger, even when that building becomes an important part of our story. This is particularly true in San Francisco where many preservationists themselves dislike anything newer than the Victorian era. Yes, it was a tragedy that many failed to appreciate the Victorian buildings and let many get torn down several decades ago, but those losses also tell another important story. It tells the story of the 1950s and 1960s when there was hope for a more equal society with inexpensive housing for the working class. Should that history be wiped from our memories?
Preservation is not just about keeping pretty, well-kept buildings, but about conveying parts of our history-not just the history of huge events, but the story of how everyone used to go to a certain corner market. Our history cannot be told only in buildings that meet someone’s criteria of beauty; sometimes our history is painful, but no less important.
