Traffic problems are an everyday concern in many cities, including Washington, D. C. A growing number of Washingtonians are turning to bicycles to get to and from work. In fact, the number of commuters who use bicycles has doubled in the city since 2007.

    Ralph Buehler teaches urban planning at the Virginia Polytechnic Institute and State University，popularly known as Virginia Tech. He has written a book about urban biking, called City Cycling. He says there is a reason why urban bike tiding is now becoming more popular.

    “Over the last 60 to 70 years, cities in America have been adapted to the automobile.”

    “Most cities took advantage of the money coming for the interstate (洲际)highway system, from the federal government, starting in 1956. There was a 90 percent federal match(补贴)so the cities only had to put up 10%. It was very tempting.(临时的).”

    In the years after World War Two, many Americans moved to suburban communities, just outside major cities, They decided to travel great distances to and from work in exchange for a home in the suburbs. Their cars became a symbol of freedom.

    But today, many people believe they can save money by living in the city.

    Greg Billing is with the Washington Area Bicyclist Association. “When a person makes a change from using a car to using a bike, he/she is saving anywhere between 8 or$9,000 a year.”

    Ralph Buehler says governments save money when people use bicycles. “Building bicycling facilities(设施) is much cheaper than building and maintaining road facilities or public transport.”

    Washington, D.C has also taken steps to protect bike riders. It approved a safe passing law and created areas on the road between cars and bikes.

    The United States Census Bureau says 4% of the city's workers ride to work by bike. The only city on the East Coast with more bike commuters is New York.

    Culture can affect not just language and customs, but also how people experience the world on surprisingly basic levels.

    Researchers, with the help of brain scans, have a shocking differences in perception (感知) between Westerners and Asians, what they see when they look at a city street, for example, or even how they perceive a simple line in a square, according to findings published in a leading science journal.

    In Western countries, culture makes people think of themselves as highly independent individuals. When looking at scenes, Westerners tend to focus more on central objects than on their surroundings. East Asian cultures, however, emphasize inter-dependence. When Easterners look at a scene, they tend to focus on the surroundings as well as the object.

    Using an experiment involving two tasks, Dr. Hedden asked subjects to look at a line simply to estimate its length, a task that played to American's strengths. In another, they estimated the line's length relative to the size of a square, an easier task for the Asians.

    The level of brain activity, by tracking blood flow, was then measured by Brain Scanners. The experiment found that although there was no difference in performance, and the tasks were very easy, the levels of activity in the subjects' brain were different. For the Americans, areas linked to attention were more, when they worked on the task they tended to find more difficult — estimating the line's size relative to the square. For the Asians, the attention areas lit up more during the harder task also—estimating the line's length without comparing it to the square. The findings are a reflection of more than ten years of previous experimental research into East-West differences.

    In one study, for instance researchers offered people a choice among five pens; four red and one green. Easterners were more likely to choose a red pen while Westerners were more likely to choose the green one.

    Culture is not affecting how you see the world, but how you choose to understand and internalize(使内化) it.

    But such habits can be changed. Some psychological studies suggest that when an Easterner goes to the West or vice versa, habits of thought and perception also begin to change. Such research gives us clues to how our brain works and is hopeful for us to develop programs to improve our memory, memory techniques and enhance and accelerate our learning skills.

    Kenya-Giraffe Conservation

    Preserve and protect Kenya's Wildlife

    After some difficult years, Kenya is back in fashion and welcoming travellers with open arms, with one main aim—help save and protect their unique wildlife. It isn't just the elephant under threat, but it's the smaller species that are also suffering, for example, Rothschild Giraffes. Now there are only 670 left in the wild and they need your help to survive.

    How can you help?

    Head out to the Soysambu Conservancy, which is home to more than 450 bird species and over 50 different mammals, including lions, zebra and more than 100 critically endangered Rothschild's Giraffes.

Get stuck into general reserve conservation but primarily focus on the research and protection of their resident Rothschild Giraffes, which is the reserve's main priority.

    Your Daily Tasks

    Work will be a combination of observational research and hands on work—five days a week.

    Minimum number of weeks is 2. This project is perfect for anyone with a passion for nature, wildlife, and the great outdoors.

    No previous conservation experience required.

    Where will you live?

    You will stay in the houses right in the middle of the reserve with other volunteers.

    The weekends will be free time, so you can explore further up the Rift Valley, Lake El-menteita itself and beyond.

    I ran into quite a few language problems while travelling with my family last summer. The most embarrassing(尴尬的) was when my Mom apologized(道歉) to the people we were staying with because her “pants were dirty”. They looked at her in amazement, not knowing how to react. You see, Mom had fallen over and gotten mud on her jeans. But in Britain, “pants” means underpants or knickers, not trousers as it does back home.

    I went to stay with a friend on the west coast last summer. Her flat was on the first floor of a high-rise building so I got the lift up. Then I wandered round for ages looking for her flat but couldn't find it. Fed up and tired, I finally had to go out to find a phone box. She explained that her flat was on the first floor, which for me meant the ground floor.

    When I asked for the “restroom” in a big department store, people kept directing me to a room with seats where I could sit and “rest”. It took me years to get through to someone that I only wanted the toilet!

    Tom-From America

    Last summer we went on a two-week family touring holiday, so Dad hired a car over the Internet. This was an old vehicle (汽车) and there turned out to be lots of things wrong with it. When he phoned the hire company and tried to explain that the lock on the boot was broken, they thought he was talking about footwear! He had no idea their word for “boot” was “trunk”. In the end we went to a garage and just solved the problem.

Keeping secrets is a burden

    "Don't tell anyone". We hear these words when someone tells a secret to us. But it can be hard to keep a secret. We're often tempted to "spill the beans(说漏嘴)",even if we regret it later.

    According to Asim Shah, professor in the Menninger Department of Psychiatry and Behavioral Sciences at Baylor College of Medicine, US, keeping a secret may well "become a burden". This is because people often have an "obsessive and anxious urge to share it with someone".

    An earlier study, led by Anita E. Kelly, a scientist at the University of Notre Dame, US, suggested that keeping a secret could cause stress. People entrusted(受委托 ) with secrets can suffer from depression, anxiety, and body aches, reported the Daily Mail.

    But with secrets so often getting out, why do people share them at all? Shah explained that people often feel that it will help them keep a person as a friend. Another reason people share secrets is guilt over keeping it from someone close to them. A sense of distrust can develop when people who are close do not share it with each other. "Keeping or sharing secrets often puts people in a position of either gaining or losing the trust of someone," according to Shah.

    He added that talkative people could let secrets slip out (泄露).But this doesn't mean that it is a good idea only to share secrets with quiet people. A quiet person may be someone who keeps everything inside. To tell such a person a secret may cause them stress, and make them talk about the secret. Shah said that to judge whether to tell someone a secret.

    Shah said that to judge whether to tell someone a secret, you'd better put yourself in their position. Think about how you would feel to be told that you mustn't give the information away. Shah also recommended that if you accidentally give up someone's secret you should come clean about it. Let the person know that their secret isn't so secret anymore.

I stood outside my front door catching my breath. After a lazy Christmas holiday, I had to recover from climbing stairs with carry-on bags and a suitcase. I looked up — Red tape crossed the door. I didn't understand French, but the one English word said enough, "POLICE". Google Translate told me I would be caught if I entered, so I didn't.

Finally, I called my rental agent (收租人). He went to the police station for more details. The thief had taken a few items from the top drawer as well as a small amount of money in the bottom drawer. Not only were my files undisturbed, but so were the TV and printer. My agent also said something about fixing the locks tomorrow and making a list for the police.

Then one day, I remembered that I had left another jewelry box in the flat. My heart sank as I thought of a gold locket (项链坠) with a picture of my late Grandma inside. When I realized the box was missing, the whole experience seemed to crash down on me. I cried. At the end of January, I received a letter from the police. The thief hadn't been found, and the case was closed. I slept with my purse by my bed. I hid my laptop when I showered. And then another challenge came — I was unexpectedly fired by my company.

One July night, I reached into my third drawer to pull out my jean shorts. I heard something fall to the ground. I looked down: It was the tiny jewelry box I thought had been stolen six months earlier. Inside was the locket with honey Grandma smiling at me, being there for me, telling me not to give up. I started to cry. I knew that things were going to be OK.
