Christmas was coming, I was considering what present I should prepare for my father.My dad never wants anything, for he is a hard person to buy for . I pulled out my phone to read text message from my mom saying that we were leaving for Christmas shopping for him when I came across a message on my phone that I had locked. The message was from my father.My eyes fell on a photo of a flower taken in Wyoming，and underneath a poem by William Blake. The flower，a lone dandelion standing against the bright blue sky，inspired me. My dad had been reciting those words to me since I was a kid. That may even be the reason why I love writing. I decided that those words would be my gift to my father.

    I called back. I told my mom to go without me and that I already created my gift. I sent the photo of the cream ­colored flower to my computer and typed the poem on top of it. As I was arranging the details another poem came to mind .The poem was written by Edgar Allan Poe；my dad recited it as much as he did the other. I typed that out as well and searched online for a background to the words of it. The poem was focused around dreaming，and after searching I found the perfect picture. The image was painted with blues and greens and purples，twisting together to create the theme and wonder of a dream. As I watched both poems passing through the printer，the white paper coloring with words that shaped my childhood. I felt that this was a gift that my father would truly appreciate.

    Christmas soon arrived. The minute I saw the look on my dad's face as he unwrapped those swirling black letters carefully placed in a cheap frame，I knew I had given the perfect gift.

    Getting more followers is something we usually associate with social media or micro messaging apps. But soon we could all have a new type of follower—a robotic one.

    Dozens of robots and technology fans gathered in Boston, US, earlier this month for the Robot Business conference. The latest developments in the world of robotics were shown to the public, and this time the trend was robots following people.

    Perhaps the most exciting development on show was the ability of drones (无人机) to follow you from the air, acting as your own personal cameraman or photographer. One example is 3-D Robotics' Iris+ drone, developed by a US-based company.

    The drone is fitted with cameras and has a “follow me” function. It connects with your GPS-enabled Android device, like a mobile phone. Then it flies and follows you around, shooting action film of you from above. The software in the drone makes sure that you're always in the center of the frame.

It can keep working for 15 minutes, as long as there aren't too many trees for it to crash into. This could be exciting for anyone who loves action sports or wants to be the star of their own short film.

    But what if you want to be one of those celebrities (名人) who have helpers carrying all their bags and doing all their chores? A robot called Budgee can help.

    Budgee, made by 5 Elements Robotics, is literally a basket on wheels.It is designed to help elderly and disabled people, or simply anyone who doesn't have enough arms for grocery bags, Wired magazine reported.It can carry up to 22.7 kg of items.

    To make Budgee follow them, its owner will have to wear a small device and use an app to set the distance between themselves and the robot.Budgee even sends a text message when it can't keep up with its owner.

     “I want you to look at the robot like he's your buddy, he's your friend. There's a relationship you develop with the robot,” Wendy Roberts, CEO of 5 Elements Robotics, told gigaom.com.

    It might not be quite the same as robotic assistants we've seen in movies such as Disney's Wall-E, where robots cater for our every need, but that idea doesn't seem quite so far-fetched now.

    Hobbs was an orphan(孤儿). He worked in a factory and every day he got a little money. Hard work changed him thin and weak. He wanted to borrow a lot of money to learn to paint pictures, but he did not think he could pay off the debts.

   One day the lawyer said to him, "One thousand dollars, and here is the money." As Hobbs took the package of notes, he was very dumbfounded (惊呆的). He didn't know where the money came from and how to spend it. He said to himself, "I could go to find a hotel and live like a rich man for a few days; or I give up my work in the factory and do what I'd like to do: painting pictures I could do that for a few weeks, but what would I do after that? I should have lost my place of the factory and have no money to live on. If it were a little less money, I would buy a new coat, or a radio, or give a dinner to my friends. If it were more, I could give up the work and pay for painting pictures. But it's too much for one and too little for the other."

    "Here is the reading of your uncle's will," said the lawyer, "telling what is to be done with this money after his death. I must ask you to remember one point. Your uncle has said you must bring me a paper showing exactly what you did with his money, as soon as you have spent it."

    "Yes, I see. I'll do that." said the young man.

    Charity is simple in theory：A heart warms, a hand reaches out. In practice, though, charity can become a troubled mix of motives and consequences. Giving can be driven by guilt, duty, praise, or perhaps the hope that giving will somehow make up for past cruelty or ignorance. Too little charity is far less than valuable. Too much can cause dependence which makes the receiver continuously ask for more.

    Giving from the heart is good. But critics have long worried about misdirected charity that does more harm than good. In his 2012 book, "Harmful Charity: How Churches and Charities Hurt Those They Help（And How to Solve the Problem）, "Robert Lupton, an experienced social worker of 40 years of community work in inner-city Atlanta, argues that charity must not do for the poor what they can do for themselves.

    Due to emergencies such as natural disasters, the afterward financial aid is greatly welcome. Mr. Lupton advocates it should focus on the development of self-supporting. The task can be carried out via, for instance, offering microloans, hiring local builders and suppliers, and trying to found self-supported, locally owned and operated enterprises. What seldom works, he argues, are untargeted handouts from far-off providers and the sudden arrival of inexperienced volunteer-tourists hoping to earn personal reputation by digging wells or mending roofs that locals are perfectly able to take care of themselves.

    Getting charity right isn't easy. But from money raising to the boom in volunteering among Millennials（千禧一代）, from the increasing worldwide willingness to give to the efforts by charity organizations to become more effective and fruitful, there is strong evidence that human beings' ability of taking care of others is growing along with their ability to help without harming.

    Charity can be as simple as holding the door for a stranger and as complex as a global campaign to get rid of malaria（疟疾）.Charity works best when it returns the weak to strength, when it helps a small town shaken by a heavy earthquake get back on its feet. A successful charity is one that eventually is no longer needed.

    What is eBay? The simple answer is that it is a global trading platform(贸易平台) where nearly anyone can trade practically anything. People can sell and buy all kinds of products and goods, including cars, movies and DVDs, sporting goods, travel tickets, musical instruments, clothes and shoes—the list goes on and on.

    The idea came from Peter Omidyar, who was born in Paris and moved to Washington when he was still a child. At high school, he became very interested in computer programming and after graduating from Tufts University in 1988, he worked for the next few years as a computer engineer. In his free time he started eBay as a kind of hobby, at first offering the service free by word of mouth. By 1996 there was so much traffic on the website that he had to upgrade(升级) and he began charging a fee to members. Joined by a friend, Peter Skill, and in 1998 by his capable CEO, Meg Whitman, he has never looked back. EBay has gone from strength to strength. It is now one of the ten most visited online shopping websites on the Internet.

    eBay sells connections, not goods, putting buyer and seller into contact with each other. All you have to do is make an e-photo, write a description, fill out a sales form and you are in business: the world is your market place. Of course for each item sold eBay gets a percentage and that is great deal of money. Every day there are more than sixteen million items listed on eBay and eighty percent of the items are sold.
