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（护照）.

    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（垃圾桶） 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（文件）. 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.

    Have you ever noticed what happens to an idea once you express it? Just talking about it or writing it down causes you to make it clear in your own mind. How can you use this to increase your brain power? Start writing.

    By putting thoughts into words, you are telling yourself the logic (逻辑) behind what you think, feel, or only partly understand. Often, explaining a thought is the process of understanding. In other words, you increase your brain power by exercising your “explain power.”

    Try this experiment. Explain how you'll increase your brain power, even if you have no idea right now. Just start with anything, and create an explanation. For example, start with “I'll learn chess,” or “I'll read an article on the mind every week.” Explain how that will help. You'll be surprised how often this becomes a workable plan, and if you actually do this, you'll have a better understanding of your brain from now.

    Another benefit of writing is that it helps you remember. Many, if not most, highly productive people are always taking notes. You can try keeping it all in your head, but if you keep a journal of your ideas the next time you're working on a big project, you'll probably have more success.

    Want to understand a topic? Write a book about it. That's an extreme example, but if you are learning something new, write a letter to a friend about it, and you will understand it better. Want to invent something? Write an explanation of the problem, why you want to solve it, and why it is worth solving, and you're half-way there.

    Writers don't always write because they clearly understand something beforehand. Often, they write about something because they want to understand it. You can do the same. Writing will help bring you to an understanding. Give it a try.

    Although English is not as old as Chinese, it is spoken by many people around the world every day. English speakers are always creating (创造) new words, and we are often able to know where most words come from.

    Sometimes no one may really know where a word comes from. Did you ever think about why hamburgers are called hamburgers, especially when they are not made with ham? About a hundred years ago, some men went to America from Europe. They came from a big city in Germany called Hamburg. They didn't speak good English, but they ate good food. When some Americans saw them eating a round piece of beef, they asked the Germans what is was. The Germans didn't understand the question and answered, “We come from Hamburg.” One of these Americans owned a restaurant. He had an idea. He cooked some round pieces of bread and started selling them. Such bread came to be called “hamburgers”. Today, “hamburgers” are sold in many countries around the world.

    Whether this story is true or not, it certainly is interesting. Knowing why any word has a certain meaning is interesting, too. This reason, for most English words, can be found in any large English dictionary.

    Children are starting on digital devices at ever younger ages, and opinions on the effects of children's digital-media habits are deeply polarised.(两极分化的).

    Jean Twenge, a psychology professor, thinks excessive use of the internet and social media makes children lonely and depressed and poses serious risks to their physical and particularly their mental health, sometimes to the point of driving them to suicide.

    However, Daniel Kardefelt-Winther of the Innocenti research office of Unicef examined various evidence and found less cause for alarm than is often suggested. Most of the studies he examined seem to show that the technology helps children stay in touch with their friends and make new ones.

    The relationship between the use of digital technology and children's mental health, broadly speaking, appears to be u-shaped. Researchers have found that moderate use is beneficial, whereas either no use at all or extreme use could be harmful.

    What worries some experts more is that screens are becoming part of the middle-class armoury(武器) for perpetuating(巩固) social advantage. Children from well-off homes are enrolled in private classes to learn skills like "How to be a YouTuber", which poorer parents cannot afford.

    We all are familiar with Android and iOS platforms as both are popular but are quite different when it comes to functionalities.

    If you are making a big move from Android to iPhone, then the first thing that counters your mind is how to get your data on the iPhone.

    Note: You need to turn on Wi-Fi on your Android & iPhone and connect them with the same network.

    So, let's get started and learn how to transfer data from Android to iPhone.

    Note: Please keep in mind that the steps might vary from device to device.

    Install (安装) the "Move to iOS" App on your Android device from the Google play store. This application is developed by Apple and available for free.

    Once you are done with installing the app, you need to grant permissions to the app. Now, follow on-screen instructions to proceed.

    Now, keep your Android aside and start your iPhone. Follow the on-screen instructions to set up your iPhone.

    The transfer might take a bit longer depending upon the size of the content.

    On your iPhone screen, you will see a screen saying," Continue setting up iPhone".

    You can continue setting up your Apple ID on your new iPhone. Once done, you will find all your data such as contacts, messages, bookmarks, pictures etc. on it.

    That's it, now you can dump your old Android phone and enjoy using your iPhone.

    My elephant adventures began in 1984 when, with our one-year-old daughter, my husband and I crossed the jungle in a jeep, slicking behind a lorry for comfort and company. The elephants standing like watchers on either side of the forest highway had us praying for our safety. One elephant made loud noise and angrily pawed (抓) the ground, warning us off. We raced away before they could attack.

    It was wise to keep elephants at a distance. We heard stories of tourists whose jeeps were overturned, and a couple of photographers were killed because they moved too close. Elephants are misleading animals. They give people an impression of being quiet and kind, so tourists think it's safe to picnic in the jungle (丛林). Yet angry elephants have knocked them down in seconds before they could take off.

    Elephants might make life unpredictable and dangerous. It's difficult for inexperienced environmentalists to even, begin to grasp this reality. I've heard city people say " We humans are encroaching (侵害) on their forests." But what's the solution?

    When a poor farmer borrows heavily to plant a crop, he'll do anything to protect it His life depends on it Elephants ruining an about-to-be-harvested corn field cannot expect to be welcomed like special guests. The battle between beast and farmer is violent.

    Experts are working on solutions to human-elephant conflicts (冲突). Some are sure to fail to like the plans to build electric fences around human settlements. Elephants rapidly figure them out and come in, around and over them.

    There are more questions than answers, for sure. But as my husband said, "More people die in car accidents every single day, in every city on the earth. But they won't take cars off the roads, will they?" So we need to seek practical ways of preventing elephant accidents.
