Anger is not wrong.I know this statement seems shocking and challenges the wildly popular “Positive Thinking” movement，which encourages us to “be full of positive energy” and “let go of our anger”. However，the truth is that anger is just an emotion，and emotions are neither right nor wrong.We do not consciously choose them.We do，on the other hand，choose how we express our emotions and there are definitely right and wrong means of expression.

     The reason we're often urged to “keep_a_lid_on”our anger is that few people ever learn proper and positive ways to express anger.Instead，we are taught that “anger is wrong” and “you should keep your anger inside”．But these messages don't change the fact that，for most of us，anger exists.

     Many popular “Positive Thinking” programmes assume that success comes from “controlling our emotion” and that this can be done by simply repeating positive statements.Interestingly，these positive slogans often include a lot of negativity.“Only losers complain！I am a winner！” is one popular saying.The belief that those who disagree with us are losers is actually quite negative and is often used as an excuse for rude language and personal attacks.

     When it comes to dealing with negative situations in our daily lives，the ability to reasonably express anger or disagreement is an important skill.But we must use balanced and non­violent methods to express our dissatisfaction.Frustration at unfair policies or treatment can certainly cause anger，but our anger can never be an excuse for abusing family members，damaging schools，attacking doctors or most seriously，engaging in terrorism.

     Instead of pretending that anger doesn't exist，we should start teaching appropriate means of dealing with anger.When we experience anger feelings in ourselves or others，what we should “let go of” is the silly idea that we can remove anger with just a few sweet words.Instead，we should find reasonable solutions to the causes of those angry feelings.We need to accept anger as a natural emotion but stop using it as an excuse for violent and destructive behavior.Anger isn't wrong，but failure to deal with it appropriately is.

    Planning to get away? Think passport first

    If you're planning to get away from it all this year, you should think passport first. Checking you have a valid passport before you book your trip takes minutes but could save you the trouble and cost of not being able to go.

    Renewing (更新) your passport before it runs out

    You can renew your passport up to 9 months before it can no longer be legally used. So take the time now and save the tears later.

    Applying for a passport for the first time

    Our eligibility (资格) checks mean that it takes a minimum of one week to issue (颁发) a passport. So make sure you don't leave it to the last minute, and apply in plenty of time.

    Help with your application is just around the corner

    Selected Post Office branches and World choice travel agents offer a Check and Send service that helps you with your application. It's convenient and you should receive your passport within 2 weeks.

    If you need to apply for or renew a passport, you can either:

    Pick up a Passport Application Form at Selected Post Office branches and World choice travel agents.

    American high school students are terrible writers, and one education reform group thinks it has an answer: robots. Or, more accurately, robot-readers—computers programmed to scan students' essays and spit out a grade.

    Mark Shermis, professor of the College of Education at the University of Akron, is helping to hold a contest, set up by the William and Flora Hewlett Foundation (WFHF), which promises $ 100,000 in prize money to programmers who write the best automated grading software. "If you're a high school teacher and you give a writing task, you're walking home with 150 essays," Shermis said. "You're going to need some help."

    Automated essay grading was first proposed in the 1960s, but computers back then were not up to the task. In the late 1990s, as technology improved, several textbooks and testing companies jumped into the field. Today, computers are used to grade essays on South Dakota's student writing assessments and a handful of other exams, including the TOEFL test of English fluency, taken by foreign students.

    The Hewlett contest aims to show that computers can grade as well as English teachers—only much more quickly and without all that depressing red ink. "Automated essay scoring is objective," Shermis said. "And it can be done immediately. If students finish an essay at 10 pm, they will get a result at 10: 01 pm."

    Take, for instance, the Intelligent Essay Assessor, a web-based tool marketed by Pearson Education, Inc. Within seconds, it can analyze an essay for spelling, grammar, organization, and help students to make revisions. The program scans for key words and analyzes semantic (语义的) patterns, and Pearson claims that it can understand the meaning of text much the same as a human reader.

    A few years ago, my husband Charlie and I had marital problems. Growing family responsibilities and financial worries took a toll on us and we began arguing frequently, often late into the night.

    However, neither of us could take the step that would end our eleven-year marriage and bring heartbreak to our three young children. Deep down we knew we still loved each other, so we determined to work it out. Through countless discussions, we began to close the gulf. The more honest we were, the closer we became.

    When I felt we were reaching solid ground, I asked my husband to give me an "eternity (永恒) ring". It was not so much the ring I wanted; it was the reassurance (保证) I thought it would bring.

    We went shopping on a beautiful summer day. We walked hand in hand along a row of jeweler's shops. Finally I found a ring I liked. While waiting for it to be adjusted, the jeweler took my left hand and glanced at my engagement ring. "May I clean it for you?" he asked. "It really doesn't sparkle like it used to." Charlie said as I slipped the ring off my finger. A few minutes later the jeweler was back. The ring shone like new!

    On the drive home, I didn't take my eyes off it. I forgot all about the eternity ring. I just couldn't believe how this old ring suddenly sparkled the way it had the day Charlie gave it to me. I had taken it for granted these past years, but with a little polish it could still make my heart beat fast.

    And that's the way it is with a marriage. You have to work at keeping it polished and new, or else the grime (污垢) of the passing years will hide the joy. I put my hand on the seat between us and spread my fingers. Charlie covered my hand with his. I felt I was lucky to be able to see the sparkle in something gold when I thought I needed something new.

    China became the first country to clone a monkey using non-reproductive cells, reducing the need to keep lab monkeys and paving the way for more accurate, effective, and affordable animal tests for new drugs.

    By December of 2017, Chinese scientists had created two clone macaques named "Zhong Zhong" and "Hua Hua" by nuclear transferring of somatic cells -- any cell in the organism other than reproductive cells. This was the similar technology used to create the famous clone sheep Dolly in 1996.

    Tetra, a rhesus monkey born in 1999, is the world's first ever-cloned monkey, but it was done using a simpler method called embryo splitting, but it could only generate four cloned offspring at a time and cannot be genetically modified to suit experimental needs, said Pu Muming, an academician at the Chinese Academy of Sciences and the director of Institute of Neuroscience, CAS. "Cloning a monkey using somatic cells has been a world-class challenge because it is a primate（灵长类）that shares its genetic makeup, therefore all of its complexity, with humans." Pu Muming said.

    "For drug and other lab tests, scientists have to purchase monkeys from all over the world, which is costly, bad for the environment and produces inaccurate results because each monkey might have different genes," Pu said. "By cloning monkeys using somatic cells, we can mass produce large numbers of genetically same offspring in a short time, and even change their genes to suit our needs," he added. "This can save time, cut down experiment costs, and produce more accurate results, leading to more effective medicine."

    Sun Qiang, director of the non-human primate research facility at the institute, said most of the drug trials are currently done on lab mice. However, drugs that work on mice might not work or even have severe side effects on humans because the two species are so different. "Monkeys and Humans are both primates, so they are much closely related and testing on Monkeys is supposed to be as effective as testing on humans," he said. This is especially useful in testing drugs for neural diseases such as Parkinson's disease, metabolic and immune system disease, and tumor, he added. "This achievement will help China lead the world research in an international science project related to neural（神经的）mapping of primate brains,"he said. However, bio labs from the United States, Japan, and European countries are also very able, and they will quickly catch up to China after the monkey cloning technology is made public, Sun added." This means we have to innovate continuously and work extra harder this year to stay ahead," he said.

    A science teacher from rural Kenya who gives away most of his salary to help poorer students has been awarded the world's best teacher and $ 1 million, beating 10,000 nominations from 179 countries. Peter Tabichi, 36, a maths and physics teacher at Keriko secondary school in Pwani Village, has won the Varkey Foundation Global Teacher Prize 2019.

    Tabichi gives away 80% of his income to help the poorest students at the poorly-equipped and overcrowded school who could not otherwise afford uniforms and books. More than 90% of his students are from poor families and almost a third are orphans or have only one parent. Drug abuse, teenage pregnancies, leaving off their studies, young marriages and suicide are common. Students have to walk 7 km along roads that can become impassable in the rainy season to reach the school and the area can be affected by drought and starvation.

    Despite only having one computer, a poor Internet connection and a student-teacher ratio of 58:1, Tabichi started a "talent nurturing club" and expanded the school's science club, helping students design research projects of such quality that many now qualify for national competitions.

    His students have taken part in international science competitions and won an award from the Royal Society of Chemistry after using local plant life to generate electricity. Tabichi and four colleagues also give struggling students one-to-one tuition in maths and science, visiting students' homes and meeting their families to identify the challenges they face.

    Accepting the prize, Tabichi said Africa's young people would no longer be held back by low expectations." Africa will produce scientists, engineers and entrepreneurs whose names will be one day famous in every corner of the world." he said.
