It is popular to travel by bike in China. China has a huge population. And it is said that there is at least one bike for every two people. Of course, many people in China ride bikes for sport or exercise, but it is also a much more commonly accepted means of everyday transportation, as compared to countries such as the United States.

    If you are living for a long time in China, chances are that you will want to buy your own bike so that you can use it whenever you want. Even if you don't use a bike for everyday transportation, owning one can be a great way to enjoy the sights in the countryside. However, if you are just visiting China, renting a bike can be a more convenient choice.

    It is important to choose the correct bike for your use. You will find that in China, the one-speed style of bike is popular. These bikes are great if you want to ride around in the city to see the sights. They are quite comfortable and easy to ride. You can often rent a bike for a day for about 15 dollars.

    However, if you wish to ride on some of the rural paths, a mountain bike style would be a better choice. They are great for different kinds of road surfaces, providing for a safer ride. If you are planning to have a wish to tour and still be able to carry packages with you, then a touring bike would be the best choice. These are the most expensive to rent, but are very suitable for carrying packages and even some of your luggage along with you.

    The iPhone the iPad: each of Apple's products sounds cool and has become a fad(一时的风尚). Apple has cleverly taken advantage of the power of the letter “i”—and many other brands are following suit. The BBC's iPlayer—which allows Web users to watch TV programs on the Internet—used the title in 2008. A lovely bear—popular in the US and UK一that plays music and vide is called “iTeddy”. A slimmed-down version(简装本) of London's Independent newspaper was stated last week under the name “i”.

    In general, single-letter prefixes(前缀) have been popular since the 1990s, when terms such as e-mail and e-commerce first came into use.

    Most “i” products are targeted at young people and considering the major readers of Independent's “i”, it's no surprise that they've selected this fashionable name.

    But it's hard to see what's so special about the letter “i” Why not use “a”, “b”, or “c” instead? According to Tony Thorne, head of the Language Center at King's College, London, “i”works because its meaning has become ambiguous. When Apple uses “i”, no one knows whether it means Internet, information, individual or intcractive, Thorne told BBC Magazines. “Even when Apple created the iPod, it seems it didn't have one clear definition,” he says.

    “However, thanks to Apple, the term is now connected with portability.” adds Thorne.

    Clearly the letter “i” also agrees with the idea that the Western World is centered on the individual. Each person believes they have their own needs, and we love personalized products for this reason.

    Along with“Google” and “blog”, readers of BBC Magazines voted“i”as one of the top 20 words that have come to define the last decade.

    But as history shows, people grow tired of fads. From the 1900s to 1990s, products with “2000” in their names became fashionable as the year was connected with all things advanced and modern. How ever, as we entered the new century, the fashion disappeared.

    The researchers say a person loses two months for every kilogram overweight they are— and seven years for smoking a packet of cigarettes a day.

    Unusually, the Edinburgh university team found their answers by analysing differences in people's genetic code or DNA. Finally they think it will show new ways of helping us to live longer.

    The group used the genetic code of more than 600, 000 people who are taking part in a natural experiment. If someone smokes, drinks, drops out of school and is overweight, it can be difficult to identify the impact of one specific unhealthy behavior.

    Instead, the researchers turned to the natural experiment. Some people carry mutations(变异) in their DNA that increase(食欲) or make them more likely to put on weight, so researchers were able to compare those programmed to eat more with those who were not. The research team also found specific mutations in human DNA that alter lifespan (寿命).

    Mutations in a gene (a set of instructions in DNA) that is involved in running the immune system could add seven months of life on average.

    People with a mutation that increased levels of bad cholesterol knocked eight months off lifespan.

    A rare mutation in a gene—APOE—linked to dementia reduced lifespan by 11 months.

    And one that made smoking more appealing cut lives by five months.

    Dr Joshi says that while genes do influence lifespan, “you've got even more influence” through the choices you make. Dr Joshi said, “We hope to discover genes affecting lifespan to give us new information about ageing and construct treatment tor ageing.”

    There are also some disease mutations that clearly affect lifespan and to destructive effect, such as the Huntington's gene. People with Huntington's often die in their 20s.

    However, in order to follow people until the end of their lives, many of the people studied were born before 1940.

    October might seem to be pumpkin month in the U.S. The holiday of Halloween (万圣节) comes on October 31. Americans around the country are already using social media to show off their pumpkin growing and carving skills.

    Pumpkins are round, orange fruits related to squashes (南瓜小果) and gourds (葫芦). People use their flesh and seeds for food, but they are also popular decorations in the fall.

    Two big pumpkins recently made headlines in the U.S. A farmer in the northeastern state of Rhode Island broke the record for the largest pumpkin ever grown in North America. Richard Wallace's pumpkin weighed 1,026 kilograms. It broke his son's record from 2015. Ron Wallace's pumpkin only weighed 1,011 kilograms last year. A schoolteacher in the northwestern state of Washington brought her large pumpkin to an event in California. Her pumpkin was the champion, weighing 866 kilograms. It turns out that Cindy Tobeck's pumpkin grew from one of the seeds from Ron Wallace's pumpkin from 2015.

    While those pumpkins are large, they are still not the largest in the world. According to the website BigPumpkins.com, Richard Wallace's pumpkin is only the second-heaviest pumpkin of the year. A man in Belgium produced a pumpkin that weighed almost 1,200 kilograms. Smithsonian magazine wrote a story about people who try to grow large pumpkins. In 35 years, the size of record pumpkins has grown from about 225 kilograms to over 1,000 kilograms. Pumpkin farmers trying to grow record fruits are taking the seeds of champion pumpkins from one year and breeding them with other large pumpkins.

    But people are not just growing pumpkins. They are carving them, too. One Twitter user from Britain recently posted a photo of a pumpkin designed to look like U.S. presidential candidate Donald Trump. No word of a Hillary Clinton pumpkin design. But one pumpkin farmer in California allows visitors to shoot small pumpkins out of a cannon（大炮）. The targets? Large paper cut-outs of both Trump and Clinton.

    ORLANDO, Fla. — Florida's busiest airport is becoming the first in the nation to require a face scan of passengers on all arriving and departing international flights, including US citizens, according to officials there. The expected announcement Thursday at Orlando International Airport alarms some privacy supporters. They say there are no formal rules in place for handling data collected from the scans, nor formal guidelines on what should happen if a passenger is wrongly prevented from boarding.

    Airports in Atlanta, Boston, Chicago, Houston, Las Vegas, Miami, New York and Washington D.C. already use face scans for some departing international flights, but they don't involve all international travelers at the airports like the program's expansion in Orlando would. The image(图像) from the face scan is compared to a Department of Homeland Security database that has images of people who should be on the flight, in order to check the traveler's identity.

    US citizens at these airports can refuse to be scanned, but the agency “doesn't seem to be doing an adequate job letting Americans know they can,” said Harrison Rudolph, an expert at the Center on Privacy & Technology at the Georgetown University Law Center.

    US citizens at the Orlando airport will be able to refuse face scans just like at the other airports if they don't want to provide their photograph, Jennifer Gabris, a spokeswoman for the US Customs and Border Protection said in an email. However, a notice about a possible rule change for the program states that “US citizens may be required to provide photographs upon entering or departing the United States.”

    “We're not talking about one gate,” Rudolph said. “We're talking about every international departure gate, which is a huge expansion of the number of people who will be scanned. Errors tend to go up as uses go up.”

    Two US senators（参议员） last month sent a letter to the Department of Homeland Security, urging that formal rules be carried out before the program is expanded. “It will also ensure a full test of this potentially sweeping program that could influence every American leaving the country by airport,” said the letter from the senators.
