Arriving in Sydney on his own from India, my husband, Rashid, stayed in a hotel for a short time while looking for a house for me and our children.

    During the first week of his stay, he went out one day to do some shopping. He came back in the late afternoon to discover that his suitcase was gone. He was extremely worried as the suitcase had all his important papers, including his passport.

    He reported the case to the police and then sat there，lost and lonely in strange city, thinking of the terrible troubles of getting all the paperwork organized again from a distant country while trying to settle down in a new one.

    Late in the evening, the phone rang. It was a stranger. He was trying to pronounce my husband's name and was asking him a lot of questions. Then he said they had found a pile of papers in their trash can that had been left out on the footpath.

    My husband rushed to their home to find a kind family holding all his papers and documents. Their young daughter had gone to the trash can and found a pile of unfamiliar papers. Her parents had carefully sorted them out, although they had found mainly foreign addresses on most of the documents. At last they had seen a half-written letter in the pile in which my husband had given his new telephone number to a friend.

    That family not only restored the important documents to us that day but also restored our faith and trust in people. We still remember their kindness and often send a warm wish their way.

    Most damagingly, anger weakens a person's ability to think clearly and keep control over his behaviour. The angry person loses objectivity in evaluating the emotional significance of the person or situation that arouses his anger.

    Not everyone experiences anger in the same way; what angers one person may amuse another. The specific expression of anger also differs from person to person based on biological and cultural forces. In contemporary culture, physical expressions of anger are generally considered too socially harmful to be tolerated. We no longer regard duels(决斗) as an appropriate expression of anger resulting from one person's awareness of insulting behaviour on the part of another.

    Anger can be identified in the brain, where the electrical activity changes. Under most conditions EEG(脑电图) measures of electrical activity show balanced activity between the right and left prefrontal(额叶前部) areas. Behaviourally this corresponds to the general even­handed disposition(意向) that most of us possess most of the time. But when we are angry the EEG of the right and left prefrontal areas aren't balanced and, as a result of this, we're likely to react. And our behavioural response to anger is different from our response to other emotions, whether positive or negative.

    Most positive emotions are associated with approach behaviour: we move closer to people we like. Most negative emotions, in contrast, are associated with avoidance behaviour: we move away from people and things that we dislike or that make us anxious. But anger is an exception to this pattern. The angrier we are, the more likely we are to move towards the object of our anger. This corresponds to what psychologists refer to as offensiveanger: the angry person moves closer in order to influence and control the person or situation causing his anger. This approach­and­confront behaviour is accompanied by a leftward prefrontal asymmetry(不对称) of EEG activity. Interestingly, this asymmetry lessens if the angry person can experience empathy(同感) towards the individual who is bringing forth the angry response. In defensiveanger, in contrast, the EEG asymmetry is directed to the right and the angry person feels helpless in the face of the anger­inspiring situation.

    When I was about 12, I had an enemy, a girl who liked to point out my shortcomings(缺点). Week by week her list grew: I was very thin, I wasn't a good student, I talked too much, I was too proud, and so on. I tried to hear all this as long as I could. At last, I became very angry. I ran to my father with tears in my eyes.

    He listened to me quietly, then he asked.“Are the things she says true or not? Janet, didn't you ever wonder what you're really like? Well, you now have that girl's opinion. Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said.”

    I did as he told me. To my great surprise, I discovered that about half the things were true. Some of them I couldn't change (like being very thin), but a good number I could—and suddenly I wanted to change. For the first time I go to fairly clear picture of myself.

    I brought the list back to Daddy. He refused to take it.“That's just for you，” he said.“You know better than anyone else the truth about yourself. But you have to learn to listen, not just close your ears in anger and feeling hurt. When something said about you is true, you'll find it will be of help to you. Our world is full of people who think they know your duty. Don't shut your ears. Listen to them all, but hear the truth and do what you know is the right thing to do.”Daddy's advice has returned to me at many important moments. In my life, I've never had a better piece of advice.

    Wellington: Huawei has started a rugby-themed media campaign in a bid to win over New Zealand's public after the country's security agency blocked the Chinese technology giant's equipment from being used in a nationwide Internet network.

    "5G without Huawei is like rugby without New Zealand," ads in New Zealand's two largest newspapers read alongside a photo of players competing in a ball. Large posters also appeal to the country's love of the sport. In November, New Zealand's Government Communications Security Department (GCSD) told Spark it couldn't use equipment from Huawei-the world's largest telecommunication equipment company—in the building of its 5G network because an unspecific "significant network security risk was identified". Spark is now in the process of seeing if it can make changes to prevent those risks, although GCSD has declined to publicly say how that would happen.

    Huawei's newspaper ad goes on to argue the decision would mean less advanced technology and higher prices for New Zealand customers. The ads come after the company last month publicly offered to only use New Zealand, rather than Chinese, staff to build the network—in a bid to ease fears—and called for an urgent meeting with the government, denying (否认) there had been any wrongdoing.

    Western spy agencies have increasingly raised security concerns about Huawei—China's largest telecommunications company-over what they say are possible links to the Chinese government, with the United States reportedly pressing Five Eyes intelligence network allies (同盟国) to avoid the company. Australia and Canada were the first countries to ban Huawei from a building of 5G networks.

The company has repeatedly denied accusations.

    New Zealand's top politicians have repeatedly denied the GCSD decision was influenced by other Western powers and say it's about the particular technology being suggested, not China. They have also denied suggestions New Zealand's diplomatic ties with China have been tense over the decision, with the official promotion of a major China—New Zealand tourism project now postponed.

    When you think back to the blackboard from your school days, what color is it? Chances are that it's green. So what's up with the name? Originally, blackboards were really black. Before wall-sized blackboards existed, late 18th-century students used their own mini boards made of slate (石板) or painted wood, according to Concordia University, Those first boards were, in fact, black, and they paved the way for the larger ones.

    In 1800 when a Scottish headmaster named James Pillans wanted his students to draw maps, the students couldn't draw the maps their teacher wanted on their tiny boards, so Pillans put several slates together to create a large board. Problem solved! From there, the idea spread quickly as teachers could finally show a concept to the whole class at one time. By 1815, the massive writing spaces were common enough to earn their own name: blackboard.

    The color change came in the 1960s when companies sold, steel plates, coated with green enamel (漆) instead of the traditional dark slate. The new material was lighter and less fragile than the first blackboards, so they were cheaper to ship and more likely to survive the journey. Teachers weren't complaining either. After all, the new "greenboards" made the chalk powder easier to erase. Plus, the enamel left less of a glare and the color was nicer to look at. At that point, people started using the word "chalkboard "as a more accurate descriptor, but "blackboard" still stuck around.
