Often in Scotland it can feel like the only difference between summer and the rest of the year is that it doesn't snow. (This isn't a guarantee!) But when the weather is good, it's a truly special place-here are some things you can do in summer when the weather is nice.

    See

    With the richest wildlife across the UK, take the chance to see some of the less common sites. On the West coast of Scotland there are lots of places where you can take a boat trip to see many kinds of whales. If you prefer dolphins, you can see the most northerly colony of bottlenose dolphins (海豚) in the world just off Inverness in the Moray Firth. Of course it's likely that you'll see seals (海豹) and many other animals on these trips too.

    Do

    The waves of Thurso right in the north of Scotland are just great. If you're not feeling brave enough to go in the water and prefer to watch from the safety of the shore then there're several major surf contests held there.

    Another very Scottish activity ideal for good weather is “Munro Bagging”. Named after Sir Hugh Munro, the 218 mountains in Scotland over 914m high are called Munros and walkers try to see how many they can climb in a set amount of time. This is not easy though-conditions can change suddenly and many of the routes are very tough (艰难的).

    Eat

    Thanks to a large Scottish-Italian population, there are too many specialist ice cream sellers. One of the most famous of them is Nardini in Largs, Ayrshire. Not only can you watch people actually make ice cream but you can sit and eat in a beautiful refurbished (翻新的) 1930s building facing the river Clyde. There's even a piano player at the weekends.

    I got into the teaching profession purely by choice. I was then in 9th grade when my mathematics teacher asked me to take a class for a few students to whom the subject seemed difficult. And believe me, I enjoyed the entire teaching session. I never knew teaching would be so interesting. I loved my freshmen and was delighted to teach my so-called students who came up with lots of good questions.

    After my post-graduation, I worked as a software developer with a public sector(部门) in Bangalore for a few years. But I realized that no job could provide me with the satisfaction that I experienced while teaching and training. I always wanted to connect with a wider group of people. In fact, I felt it was a timely realization for me to choose the teaching profession. I applied to a few colleges, and finally I was chosen as a lecturer, and I had to lecture graduate and post-graduate students in a college.

On the first day, I was nervous thinking that I had to teach the senior classes. But now I can say that giving lectures was one of the best experiences of my life. I was a Computer Science and Information Technology lecturer, but I tried to help my students with subjects that were not within my domain(范围). It was a new feeling to me every morning before I went to the classes. I used to feel energized and excited thinking that the class would be lit up with bright faces to greet me, "Good morning, Madam."

    To me each day was a new beginning, with new feelings, new experiences and new queries(疑问). I loved to explore their young minds and read their inquisitive faces when a particular topic seemed tough. It was extremely challenging to motivate them to participate, think critically, question and also respect others' points of view. Though few things never seemed easy, it was extremely exciting to assure them that they really can. That is the reason I love to teach.

    Forty-three years seems like a long time to remember the name of a mere acquaintance. I have forgotten the name of an old lady who was a customer on my paper route. Yet it seems like just yesterday that she taught me a lesson in forgiveness.

    On a Saturday afternoon, a friend and I were throwing rocks onto the roof of the old lady's house. The object of our play was to observe how the rocks changed to missiles （导弹）as they rolled to the roof's edge and shot out into the yard like comets （彗星）falling from the sky. I found myself a perfectly smooth rock and sent it for a ride. However, it slipped from my hand as I let it go and headed straight for a small window. At the sound of crashed glass, we knew we were in trouble and ran away.

    A few days later, when I was sure that I hadn't been discovered, I started to feel guilty for her misfortune. She still greeted me with a smile each day when I gave her the paper, but I was no longer able to act comfortably in her presence. I made up my mind to save my paper delivery money, and in three weeks I had the seven dollars that I calculated would cover the cost of her window. I put the money in an envelope with a note, and put the envelope through the letter slot in her door.

    The next day, I handed the old lady her paper and was able to return the warm smile that I was receiving from her. She thanked me for the paper and said, “Here, I have something for you.” It was a bag of cookies. I thanked her and began to eat the cookies as I continued my route.

    After several cookies, I felt an envelope and pulled it out of the bag. When I opened the envelope, I was surprised. Inside were the seven dollars and a short note that said, “I'm proud of you.”

    Twenty-one years ago, my husband gave me Sam, an eight-week-old schnauzer（雪纳瑞犬）, to help ease the loss of our daughter. Sam and I developed a very special bond over the next years.

    At one point, my husband and I decided to move to a new home in New Jersey. Our neighbor, whose cat had recently had kittens, asked if we would like one. We were a little apprehensive about Sam's jealousy and how he would handle his turf（地盘）being invaded, but we decided to risk it.

    We picked a little, gray, playful ball of Fur. She raced around chasing imaginary mice and squirrels and jumped from table to chair in the blink of an eye, so we named her Lightning.

    At first, Sam and Lightning were very cautious with each other and kept their distance. But slowly, Lightning started following Sam — up the stairs, down the stairs, into the kitchen. Later, when they slept, it was always together; when they ate, it was always next to each other. When I took either one out, the other was always waiting by the door when we returned. That was the way it was for years.

    Then, without any warning, Sam was diagnosed as having a weak heart. I had no other choice but to have him put down. The pain was nothing compared with what I experienced when I had to walk into our house alone. This time, there was no Sam for Lightning to greet and no way to explain why she would never see her friend again.

In the following days, Lightning seemed heart-broken. I could see the disappointment in her eyes whenever anyone opened the front door, or the hope whenever she heard a dog bark.

    One day as I walked into our living room, I happened to see Lightning was lying next to the sculptured replica（复制品）of Sam that we had bought a few years ago, one arm wrapped around the statue's neck, contentedly sleeping with her best friend.

    British children generally learn how to ride a bike at a young age. I am an exception to that rule. It's not my dad's fault—he tried to teach me. I remember cycling around the neighborhood. To be honest, though, I never saw the appeal. One of my earliest memories is falling from my bike and into some spiny(多刺的) plants. I definitely didn't want to repeat that.

    So I stopped learning. My dad wasn't going to waste his time teaching someone who didn't want to be taught. Time passed and I accepted that I couldn't ride a bike. It never affected my life in high school because I lived close enough to walk.

    I never felt like I was missing out until I couldn't go on a bike ride with friends in Byron Bay because I was only confident that I could go on a flat surface in a generally straight line. So when the opportunity came up to bike the wall of Xi'an, I wanted to prove to myself that I could do it and make up for missed time. So, with a friend who is very patient, I got on the bike. Instantly nothing came flooding back to me, I had absolutely no idea how to start! "Push off with one foot hard" was my instruction. It sounded simple enough but it just would not happen. Until something clicked and suddenly I was off, going in a straight line on a flat surface and managing to avoid the Chinese tourists who obviously found exaltation on my face.

    At 22 years old, I finally learnt how to ride a bike, and nothing can hold me back.

    People in Japan tend to live longer and stay healthier in their later years, with an increasing number of old people living alone. Japan is on a fast track to "ultra-age" with people aged 65 or above accounting for 28 percent of its total population in 2019；it was 26.7 percent in 2017. On the other hand, the number of births in 2019 fell to its lowest (about 941,000) since records began in 1899.

    Demand for care services for elderly people has increased. A shrinking (缩小) working population means fewer able-bodied adults are available to look after the elderly. State-provided facilities for the elderly are not enough which causes elderly people to turn to private ones but they are expensive.

    The country will be short of 380,000 of health nurses by 2025. The government has to turn to advanced robots to meet the shortage. A study found that using robots encouraged one third of the people to become more active and independent. Yet there is no robot that can provide the emotional support to the elderly.

    Japan provides a case study for China, which is also faced with a fast aging population. 17.23 million babies were born in China in 2019, about 630,000 fewer than in 2018. People aged 60 accounted for 17.3 of China's population in 2019. With a shortage of elderly care facilities and unbalanced supply, China may find it hard to deal with the rapidly increasing number of senior citizens.

    To meet the challenge, the Chinese government should make policy changes, which Japan is unwilling or unable to do or even consider. China should pay attention to the signals its aging population is sending and take proper and timely action.
