A latest research led by researchers from the National University of Singapore (NUS) has found a clear link between the color of a taxi and its accident rate. An analysis of 36 months of detailed taxi, driver and accident data from two fleets of yellow and blue taxis in Singapore suggested that yellow taxis have fewer accidents than blue taxis. The higher visibility of yellow makes it less difficult for drivers to avoid getting into accidents with yellow taxis, leading to a lower accident rate.

    The study was led by Prof Hou. To test whether there was a relationship between the color of a taxi and the number of accidents the taxi had, the research team analyzed data collected by the largest taxi company in Singapore. The researchers found that yellow taxis have about 6.1 fewer accidents per 1,000 taxis per month.

    They also studied the economic effect of changing the color of the entire fleet of taxis to yellow. The Singapore taxi company involved in the study owns about 16,700 taxis in a ratio (比例) of one yellow to three blue taxis. If a commercial decision is made to switch from blue to yellow taxis, 76.6 fewer accidents will occur per month or 917 fewer accidents per year.

    Assuming an average repair cost of $1,000 per car and a downtime of six days, the color of all taxis to yellow could produce an annual saving of $2 million.

    "We are eager to continue to validate(证实) the findings of our study by looking at the use of yellow in other types of public transport, such as school buses. For example, we hope to compare the accident rates of yellow school buses against those of other colors to find out if yellow is indeed a safer color for school buses. Besides, we're also interested to look at private-hire vehicles and do a comparison of the accident rates of vehicles that are of different colors, "explained Prof Hou.

    My daughter Alisa was born blind in her right eye and was bullied (欺侮）pretty severely in school. So I quitted my job as a babysitter and then schooled my daughter heart and soul at home.

    A year ago a boy of 14 befriended my daughter on Facebook after reading something Alisa wrote about bullying. Today he messaged her and asked if she would like six tickets to a Colorado Rockies baseball game. They have never met in person but she said, “Sure! That would be great.”

    Then I received a call from his mother explaining why her son had chosen my daughter. She said he thought my daughter deserved them because of all the good she does in the community. Her son, she explained, had experienced a similar situation and was also home schooled.

    What she said is true. Now my daughter Alisa continues to teach groups of girls in trouble in our community how to look within themselves for the positive and how to be their own person.

    Everything taken into consideration, we decided to meet the mother and the boy at a local bike shop. After meeting, the boy approached my car and my daughter gave him a hug and thanked him for his generosity. She told him that she had never been to a baseball game and that she was going to take her entire family, including myself, her dad, little sister, her cousin and an aunt who has brain cancer.

    We all thanked one another, got in our car, and went our way. As we drove home my daughter opened the envelope. Inside it were the tickets and ＄100 each to buy hot dogs, pay for parking and not have any worries but a great time.

    My daughter has always been the giver and now she and our family are the receivers and I can not tell you how incredibly honored we feel to be on the other end. What an incredible young man to have such a kind idea.

    Finding a friend doesn't seem like a difficult job. However, bad friends are easier to find than good friends these days. If you're sitting there and wondering if you have a bad friend, let me define it for you.

    A bad friend is someone whose jealousies and insecurities outweigh their love for someone. They might want to be a good friend but they're too messed up in their own head to ever actually do it. They wonder if their friends are going out without them or if they're being forgotten and left behind. People who are violently insecure don't have what it takes to be the quality of a friend.

    Bad friends are narcissistic(自恋的). They look for any opportunity to bring the conversation back to them. Worse, they might not even be aware that they're doing it. In their mind, they might think they are the best friend ever, which is truly frightening.

    Bad friends are quick-change. They're by your side when you're fun and you have something to give them but as soon as you're going through a difficult time, they will become indifferent quickly. They won't bring you cold medicine. They won't give you a ride to the doctor, everything they do is self-serving.

    If you find a friend who has these same characteristics, send them to your bad friend list immediately. Your friends are supposed to be the solution to your problems, not the source.

    I believe your twenties are a time when you need positive and helpful friends. In such a time, friendships aren't easy to maintain like they once were in school. Now we actually have to put work into it, we have to make a conscious effort to keep the friendship going. You need to ask yourself, "Is this person worth it? Do they treat me like a fool or what?" if you have doubts, try to make them clear by considering the past experiences. Toxic(有毒的) friendships do nothing but drag you down. My point is that you have to take care of yourself and stop getting in touch with your bad friends. Only surround yourself with people who bring out the best qualities in you. It may sound cruel but it's true.

How to Make a Homemade Gift

{#blank#}2{#/blank#} While cards can be purchased at nearly any supermarket or department store, making one yourself can make a statement about the time and effort you're willing to spend on the recipient. The most important part, though, is the words you write on it. Try to be sincere and honest while writing something.

Prepare love coupons (礼券). These are fantastic gifts for family members and close friends. The basic idea is to make a small book of "coupons" from zero. {#blank#}4{#/blank#} For example, if you're giving the coupons to your mother, you might write "I will go to a movie with you" on one of the coupons.

Make a pack of cards. {#blank#}5{#/blank#} For this gift, you take an ordinary pack of cards and turn it into something special by writing your praise for the gift recipient on each one. When you give the gift, offer to use the cards to play your favorite card game together.

A. Write a heartfelt card.

B. Make a piece of DIY art.

Don't ignore (忽略) the difference teenagers can make.

John Michael Thomas, 14, Florida

When John Michael Thomas decided to honor his friend and classmate Elizabeth Buckley, who died from cancer, he remembered how much she loved peacocks (孔雀).

He wanted to build a life-sized peacock fountain (喷泉) in Elizabeth's favorite park in the city. He thought it could be a place for people to relax and be inspired.

John Michael raised $52,000 to build the fountain.

Barrett England, 13, Utah

The wheels began to turn for Barrett England when he heard about Karma Bike shop, a place where young people can earn free bikes by reading and performing community (社区) service.

Barrett visited Karma's owner with his idea: He would collect and repair used bikes and donate them to the shop.

He expected to get about 10 donated bikes. In the end, Barrett received 39.

Zachary Blohm, 15, Wisconsin

The 25-year-old playground at an elementary school near Milwaukee, Wis. was so small that only 70 of its 575 students could play on it at a time.

That's when Zachary Blohm saved the day. He and some volunteers wanted to build a huge playground. To raise money, Zac planned T-shirt and bake sales, sold tickets and more. He held monthly money-raising events for more than a year. Overall, he collected $130,000 — enough to finish his project.

Jack Zimmerman, 16, New Jersey

For some people, finding a meal is as simple as opening the refrigerator. For more than 366,000 hungry kids in New Jersey, it's not that easy.

That fact didn't sit well with Jack Zimmerman, who organized a drive to lessen childhood hunger in his state. His goal: create 40,000 packaged meals that could be donated to those in need.

On game day, Jack and his volunteers started their work. After the final count, the team had packaged 47, 124 meals—well above Jack's goal.
