Urban public bike service isn't a new phenomenon. Government-sponsored public bike systems have been introduced into many cities in China Mobike, a new kind of public bike rental service, started in Shanghai and has expanded to Beijing. People can use this service by scanning the QR code(二维码) on the bike to unlock the smart lock. The standard cost of this service is 1 yuan per 30 minutes. Users can pay with popular mobile payment methods such as Alipay and WeChat. Mobike now has more than 10, 000 bikes in Shanghai, allowing most riders to find a bike anywhere within a diameter(直径) of 300 meters. Many people ride a Mobike for a short trip, such as from home to the subway, subway to the work place or to a grocery store. Experts say Mobike is a good supplement(补充) to the public bike rental service since city people are now fond of “Green Riding”, and environmentally-friendly means of transportation. Just because of this, the company providing the service is increasing the number by hundred every day.

    Technology is forever changing the way we get our news. Many people now get a lot of their news on electronic devices, instead of traditional media, such as newspapers, television or radio. An increasing number of people also report turning to social media for information

    Now, there is a new technology that could greatly change the way we get the news: computer-created news readers. Recently, China launched what it called the worlds first artificial intelligence, or Al news presenters.

    The news readers, supported by machine learning technology, are based on two real-life Chinese newsmen. One is able to present newscasts in English, the other, in Mandarin Chinese Report said machine learning was used to examine video images and sounds of the two newsmen. Similar technology has been used to create video products known as “deepfake” videos. "A deepfake a video that looks real, but was electronically changed. Such videos can make people appear to say things they never said

    It's said that the Al presenters will be a great improvement to the news team because they "can work 24 hours a day" on its website and on social media. One of the presenters even promised to work tirelessly" to keep people informed. Some machine learning experts said the system showed off Chinas latest progress in voice recognition, text-to-speech technology and data analysis

    Others wondered about the effects robots might have on employment and workers. Some people argued that only low-level jobs requiring heavy labor will be easily replaced by robots. Others praised the technology as a way for companies to make money from low-cost labor machines. Some businesses have experimented with similar technology for possible use in news operations.

    Britain's BBC recently released a video that used machine learning to make it look like one of its news readers speaking different languages. The London-based company that developed the system says its goal is to "remove the language barrier" for many different kinds of video across the internet. Also, Amazon's working on Alexa smart speaker system to create a special news reader voice. Amazon is reportedly preparing to launch Alexas news reader voice in the near future

    Scientists in London say they have found the best diet for both humans and the planet. If the world followed the so-called "planetary health" diet, the scientists told Reuters that each year more than 11 million early deaths could be prevented. Scientists say that the way we produce and eat food is very bad for the planet. For the health of the planet, they claim the same diet would reduce greenhouse gases and save more land, water and animals.

    Tim Lang, a professor at Britain's University of London, co-led the research. He told Reuters, "The food we eat and how we produce it determines the health of people and the planet, and we are currently getting this seriously wrong." Lang added that the world's population is expected to grow to 10 billion people by 2050. If we want to feed everyone, he explained, we all need to change what we eat and the way we eat by "improving food production and reducing food waste."

    Well, what do you eat on the planetary health diet? The scientists who created this diet say it is largely plant-based but still has small amounts of dairy, fish and meat. The diet calls for cutting red meat and sugar by 50 percent and doubling the amount of nuts, fruits, vegetables and legumes.

    Food situations around the world are not equal. In certain areas, this would mean great changes. People in North America, for example, eat 6.5 times the recommended amount of red meat. On the other hand, people in South Asia eat only half the amount suggested by the new planetary health diet. Meeting the targets for vegetables would need big changes in other areas. In sub-Saharan Africa, people on average eat 7.5 times the suggested amount of vegetables like potatoes and cassava.

    The scientists admit their goal will be difficult to achieve. But for them doing nothing is also not an option. Willet said, "If we can't quite make it, it's better to try and get as close as we can."

    My family moved from Taiwan to a small town in central Georgia, where my dad got a visa for his family and a job. I had just learned English, and from what little I could gather from my friends, Santa Claus would come down one's chimney and put toys in one's stocking on Christmas Eve! What a great country, I thought. After I looked up "stocking" in my Chinese-English dictionary, I knew what I had to do and always expected that day.

    Finally, the big day came. On that wonderful night, after everyone went to bed, I sneaked out of bed, took my longest, cleanest knee sock and attached it to a nail already on the mantel (壁炉). Obviously, the previous owners of this house were no strangers to this Santa character. Gazing at the sock and imagining the delicately-packed gift in it, I couldn't help giggling (咯咯笑). For the first time, I found it hard to fall asleep.

    And for the first time, I woke up before everyone else in the early morning. Then I headed straight to the fireplace and was even ready for what to say after seeing the gift. However, what happened next was the least thing I wanted to mention. On the nail was the empty and lonely sock. I was hit with the reality of the empty sock and the biggest lie ever told. I tried my best to hold back my tears but failed. Bursting into tears, I quickly took down the sock and stuffed it in the back of a drawer.

    Every December since then, the topic of Christmas memories would unavoidably come up, and I would amuse my friends with my poor-little-me story. I had to make it as funny as possible, or else I would cry once again. I didn't know whether any of my audience ever noticed the sparkling tears hidden in my eyes.

    How could I know that Santa was just late? Nine years ago, on Christmas Eve, I heard a knock on the door when I was watching TV. Unwillingly, I dragged my feet and opened the door.

    Through tear-blurred eyes, I recognized the handwriting on the card.

    The big day had finally arrived. I had won the local speech contest (比赛), representing Madison Middle School. Here it was the state competition. I waited backstage for the host to announce My name.

    Even though I had practiced much, I was extremely nervous. My heart was thumping, my palms were sweating, and my mouth was dry. "Calm down," I told myself. Still, picturing an audience of teachers, parents and classmates made me want to disappear totally.

    Mr. Patrick, who taught me to give speeches, reminded me, "You'll do great. You're prepared. You've come this far."

    Mr. Patrick was right. I was ready for this, and besides, I won first place in the earlier contests. Yet, when I pictured all eyes on me waiting for me to mess up, my heart was gradually sinking into my stomach.

    "You can't back out now," I told myself as Mr. Nichols, the host, announced my name and the title of my speech, "My Hero."
