A drug that is used to treat serious bleeding could save thousands of lives of mothers giving birth. A world test of the drug found it reduced (降低) the risk of bleeding deaths during childbirth by nearly one third. The study included 20,000 women in 21 countries, mainly in Africa and Asia. The test was carried out by London School of Hygiene and Tropical Medicine. The drug is called tranexamic acid (凝血酸). It is low-cost and researchers said it does not cause serious side effects (副作用) for mothers or babies.

    The drug is used to treat mothers for serious bleeding during childbirth. Postpartum hemorrhage (产后出血) is the main cause of mothers' death around the world, according to the World Health Organization.

    Haleema Shakur is the project director for the test. She said though medical condition is improved in many countries, serious bleeding after childbirth remains a big problem in some parts of the world. “It's one of the biggest killers of mothers. In Africa and Asia, about 10% of women will end up with serious bleeding.” The drug works after a mother gives birth.

    Shakur said the best results were reported when the drug was given to women as soon as possible after childbirth. “The earlier you give it — within the first three hours after giving birth — the better the result is.”

    The next step will be to provide training for doctors and nurses on how to use it and then to find where the drug is needed. During the test, women were given the drug in a hospital. But researchers are looking for easier ways to use the drug so it can be more widely used in small clinics and the countryside.

    March, April and May are months full of festivals and events all over the world. Here are some wonderful festivals around the world that happen in spring.

    SongKran--Thailand

    Dates: 13th-15th, April

    In Thailand, it's time to celebrate the coming monsoon season, which will bring the rain many people have been looking forward to. They celebrate it with a festival called Songkran，when people head out to the streets with water guns to spray(喷，洒）everyone who walks past. If you walk on the streets where the festival is celebrated, prepare to get soaked!

    Naghol--Vanuatu

    Dates: Every Saturday from April to May

Every year, villagers come together to celebrate the harvest of yams, an important part in the people's diet in Vanuatu. The festival is most famous for its “land diving ceremony”. During the ceremony men and boys dive to the ground from high wooden towers with only two thin vines(藤条) attached to their ankles(脚踝). The divers' heads have to lightly touch the ground when they jump—something very dangerous if the vines are not measured properly.

Cherry Blossom Viewing —Japan

    Dates: The cherry blossom season is different from year to year depending on the weather forecast.

    The cherry blossom season has huge importance to the people of Japan, who celebrate the days when the flowers finally blossom. Only a few days later, the petals(花瓣）fall to the ground, like pink snowflakes. This is one of the most beautiful things to see. In Japan, almost everyone has picnics in the parks to view the flowers.

    During his freshman year at Mission Viejo High School in the United States, Chance Blanscet told his parents he wanted to score a touchdown (触地得分) for the Diablos football team.

    Born with dwarfism (侏儒症), Blanscet, now 16 and a sophomore (高二学生),

doesn't have the size of a football player, but his courage more than enough makes up for this. On May 19, Mission Viejo High's cheerleaders called Chance's name as he seized (抓住) his opportunity.

    Taking a hand-off (传球) from the receiver, Blanscet raced toward the end zone as fast as he could, while his teammates created a path for Blanscet straight across the goal line.

    After scoring his touchdown, the players lifted him up and celebrated.

    Blanscet spent the first six years of his life in local hospitals before getting adopted (收养) by parents Andy and Michele Blanscet.

    When they brought him home, he couldn't speak and could only walk with the help of a walking frame (助行架). But as he grew older and stronger, he needed less medical attention.

    Blanscet was received with open arms at his high school and became interested in football after attending the first game of his freshman year.

    After meeting Diablos head coach Bob Johnson, he was eventually asked to lead the team's junior squad (小队).“This is an amazing group,” Michele Blanscet said. “They're so supportive. They view him for his abilities, not his disabilities.”

    Blanscet's video class filmed the entire event, from Blanscet leading the team to his post-touchdown celebration. And instead of shouting “Diablos,” the players shouted “Chance”.

    That's a thing of a lifetime,” Johnson said. “He tries to make it to every game. This is just a special thing they wanted to do for him.”

    The scenes will be used for a video Blanscet is working on for class. It will also include highlights of football games from last fall, and interviews with players and cheerleaders.

    “We needed something big to go with it,” said Marty Deutschman, who has been Blanscet's one-on-one instructor (教员) for three years. Deutschman organized the event about a month ago.

    Everyone was immediately on board. “We're so impressed with the school spirit,” Andy Blanscet said. “The students are there for each other and they were able to put together such a big event in a short time with all that enthusiasm.”

    WeChat, the Chinese social media smartphone app, saw an increase in user numbers of 41 percent year on year to 500 million at the end of last year, in a sign that parent company Tencent is extending its reach for the mobile Internet. As one of the largest Internet integrated service providers in Chinaand one of the most Internet users in China, Tencent's profit grew 24 percent to RMB 20.98 billion per year, slightly higher than forecasts, driven mainly by online gaming profits. It is unclear how much WeChat contributed to Tencent's profits but the app's growth is a strong indicator of the company's long-term health as it tries to adjust its business to be more suitable for mobile devices.

    "We extended our leadership in games and online media, and made breakthroughs in emerging platforms such as online security and mobile payments." Ma Huateng, Tencent chairman, said in a statement. WeChat is the second highest ranked social app in China, behind QQ, Tencent's another chatting app, which claimed to have 815 million registered monthly users at the end of 2014.

    Tencent has been unwilling to earn money through WeChat by flooding it with advertising, which could influence the users' experience. But this is expected to change. Some analysts anticipated(预期) that advertising would be introduced on a large scale later this year. Early attempts to test ads on the service have not always gone smoothly. After a BMW ad was introduced on some users' feedbacks in January, many users who were not targeted by the brand's marketing complained of "discrimination" by Tencent's data mining algorithm(数据挖掘算法). They claimed it unfairly treated them as not wealthy or successful enough to view the BMW ad.

    I didn't know how to say no, and was afraid to tell people what I wanted. Instead, I got myself tangled (纠结的) in a web of obligations, anxiety, and white lies.

    The worst thing was that I didn't even realize what I was doing. I thought I knew how to say "no"—but couldn't remember the last time I had. Like a lot of people, I just wanted to be accepted, appreciated, loved—and that the only way to get those things was to put everyone else's needs before my own.

    I never seemed to have time for things I really wanted to do. I'd like to learn Spanish, write more fiction, and travel. These aren't huge, unrealistic goals. And yet, my people-pleasing ways dramatically cut into my free time to pursue these desires.

    But recently, I decided I'd had enough. As an experiment, I began standing up for myself, even at the risk of alienating (使疏远) myself from everyone and having my entire life come crashing down around me. Several days ago, a good friend asked me to go for coffee at 5 p.m. I was planning to hit the gym and then binge—watch Mad Men for the millionth time. I said, "Sorry, I've got things I want to do tonight." She said, "That's fine. Maybe another time." It was all so painfully simple that I wanted to cry.

    Saying "no" is so much easier. If someone asks me to do something I have zero interest in, I'm polite but honest. "I'm sorry, I don't think that's really for me." The words slip out my mouth faster than some other lame excuses.

    Learning how to say "no" has added several extra hours to my days, days to my weeks, and what feels like months to my years. I no longer have to back-burner my plans to help friends with their job search, or set aside a weekend to read a book draft by someone I barely know. Saying "no" has set me free.

    Of the several films Hirokazu has made about childhood and children, this one is the most modest, but no less pleasing for its delicate style and small setting. I Wish was originally called Miracle, and the change is for the better. The two-word title makes you want to know who's wishing for what, while the single word sounds plain and self-praising. This wise and funny film works small miracles in describing such a moment when kids turn from the wishfulness of childhood into shaping the world for themselves.

    The sweetly reflective hero, a sixth-grader named Koichi, starts out by wishing for a volcano to erupt. Not just any volcano, but the one that towers above his town, smoking heavily and giving off ash. An eruption would lead to a withdrawing, which would lead, at least in his mind, to a reunion with his father and kid brother, who've been living in Hakata while Koichi lives with his mother and retired grandparents in Kagoshima. The volcano, knowing nothing of this, refuses to erupt, but Koichi hears of another approach to realizing the desired miracle.

    One of the pleasures of I Wish is watching how kids behave—how Koichi attacks his dinner, for example. Another pleasure is rediscovering how kids think. These kids can be logical and ever so tricky. But children's thought processes can also be fancy. A boy wishes he could play baseball like one of baseball stars, who eats curry for breakfast; so he, too, starts eating curry for breakfast, instead of practicing on the field. Another boy tries to wish his dead dog, Marble, back to life. And what does Koichi finally wish for? I wish you'd see this delightful film to find out.
