China has the highest adoption rate in the world for technology-enabled payment systems, according to a report released on Wednesday. The report, from the market research firm Nielsen, is based on a survey of 13,000 respondents in 26 countries.

    The survey showed that 86 percent of Chinese respondents said they paid for online purchases during the past six months via digital payment systems compared with a global average of just 43 percent.

    "Chinese consumers have more payment choices for products and services than ever while digital payments will continue to win over more Chinese consumers due to its convenient nature," said Kiki Fan, managing director of Nielsen China.

    The increasingly popular payment method is part of the rapidly evolving purchasing behavior of Chinese consumers. About 98 percent of the respondents in China, the world's largest e-commerce market, said they had made purchases online.

    The majority of them still make online purchases via computers, but the number of those who use mobile devices to make purchases is growing fast and is significantly higher than the average in other surveyed countries.

    At 71 percent, food-related businesses topped the list of purchases made via smart phones while event ticket purchases stood at 51 percent.

    The rising use of digital payments has attracted numerous players to the Chinese market.

    Apple Inc launched its contactless payment system Apple Pay in the Chinese mainland last month. It allows users of the iPhone 6 or more advanced versions, certain iPads and Apple Watches to pay by their devices in bricks-and-mortar stores.

    Apple's rival Samsung Electronics Co Ltd is expected to bring its own mobile payment service to China in mid-March—Sam-sung Pay.

    China's Internet giants Alibaba Group Holding Ltd and Tencent Holdings Ltd have already taken about 90 percent of the mobile payment market, but industry observers said the competition is just about to start.

    Why read, and sometimes even write poetry? That question is not difficult to answer if we change the word poetry to songs.

    I sing when I feel good. When I sing my favorite songs, I feel even better. Sometimes when I am listening to music and to the song words, I feel that it was written for me. A good song always makes me feel something. There are songs that I sing in my head between classes and songs that I want to sing when the school bell rings by the end of the day. They help me get through the day.

    They are like bright and warm colors in the middle of grays and shades. I like songs about love and friendship. The extraordinary thing is that my feelings are more special when I sing my favorite songs in English.

    I also like reading. I used to avoid poetry until an e-friend told me I should recite poems and not look up the meaning of the words. Poetry uses many difficult words and idioms, but the best thing is to just forget about them. In the beginning I felt quite strange. Now I always lock the door. Reading aloud gives you a strange feeling, but when you have some practice and fall into the rhythm, and the sounds of the words, it is really a special experience.

    I started with small poems, but now I think I most like long poems. I have different feelings with different poems. When I have had a bad day at school, I read Keats and forget everything. When I am sad I read Wordsworth by the light of a candle. When the poem is finished, I close the book and my sadness is gone.

    A couple had a son eleven years after they married. They were a loving couple and the boy was the apple of their eye. When the boy was around four years old, one day the father was very tired after work so he asked his wife to pick up their son. The mother, who was very busy in the kitchen, totally forgot about it.

    Later the boy lost his way on the street. When the son was found missing, the mother hurried to look for him, but she didn't find him. The mother felt very sad and didn't know how to face her husband.

    When the father went to the police station after hearing that the son was missing, he looked at his wife and said just four words. What do you think the four words were? The husband just said “I love you, darling.”

    The son was missing. If she had picked him up earlier, this would not have happened. There is no point in blaming (责备) anyone. His wife had also lost her only child. What his wife needed at that moment was comfort and understanding from her husband. That is what the husband gave his wife. Several weeks later, with the help of the police, the couple finally found their lost son. The family's relationship became stronger over that time.

    Sometimes we spend lots of time asking who is to blame. We miss many chances to give each other support and let each other feel the warmth of human relationships. Get rid of all your unwillingness to forgive, selfishness, and fears and you will find the world is much more wonderful.

    It's been a hard time for rhinos (犀牛) lately. Recently the International Union for Conservation announced the western black rhinos had died out in the wild. It was last seen in western Africa in 2006. Now, those who work to protect the animals are trying to make sure that won't happen to other rhinos.

    19 south-central black rhinos in South Africa were driven to an area nearly 1,000 miles away, which was said to be the gentlest and quickest way to transport the animals. They were taken to a new home that would keep them safe from hunters.

    Though it is not allowed to hunt rhinos, many are still killed for their horns, which can sell for as much as $ 30,000 each. Most of them are used to make drugs as traditional medicines in Asian countries. Some people believe that the horns work well in treating pain, fever and even cancer. However, there is no medical evidence yet.

    Black rhino population began falling rapidly in the second half of the 1900s because of poaching. In fact, some people still hunt the animals at the risk of being put into prison. And many of the places where the animals used to live in were destroyed when people started building farms on the grasslands. Until the 1960s, about 65,000 black rhinos lived throughout most of Africa. Today, fewer than 5,000 are left—most of them in zoos and wildlife reserves.

    South Africa has the largest population of rhinos in the world. Poaching is an especially big problem in that country. So far, more than 340 rhinos have been killed there. Since 2003, the Black Rhino Expansion Project has been helping the south-central black rhinos in South Africa. The group works with landowners to find areas where rhinos can live safely away from hunters.

    So far, the group has successfully saved about 120 rhinos. Leaders of the project say the south-central black rhinos have seen a rise in numbers. It is hoped that, with continued support, these rhinos can escape the unfortunate result of the western black rhinos.

    Watching some children trying to catch butterflies one hot August afternoon, I was reminded of an incident in my own childhood．When I was a boy of 12 in South Carolina, something happened to me that cured me forever of wanting to put any wild creature in a cage.

    We lived on the edge of a wood, and every evening at dusk the mockingbirds would come and rest in the trees and sing. There isn't a musical instrument made by man that can produce a more beautiful sound than the song of the mockingbird.

    I decided that I would catch a young bird and keep it in a cage and in that way would have my own private musician.

    I finally succeeded in catching one and put it in a cage. At first, in its fright at being captured, the bird fluttered about the cage, but eventually it settled down in its new home. I felt very pleased with myself and looked forward to some beautiful singing from my tiny musician.

    I had left the cage out on our back porch, and on the second day of the bird's captivity(囚禁) my new pet's mother flew to the cage with food in her mouth. The baby bird ate everything she brought to it. I was pleased to see this. Certainly the mother knew better than I how to feed her baby.

    The following morning when I went to see how my captive was doing, I discovered it on the floor of the cage, dead. I was shocked! What had happened! I had taken excellent care of my little bird, or so I thought.

    Arthur Wayne, the famous ornithologist, happened to be visiting my father at the time, hearing me crying over the death of my bird, explained what had occurred. “A mother mockingbird, finding her young in a cage, will sometimes bring it poison berries. She thinks it better for her young to die than to live in captivity.”

    Never since then have I caught any living creature and put it in a cage. All living creatures have a right to live free.
