“Keep out or I'll chase you out! This is my property!” You hear this every spring. It is a long musical sound —a bird song! Birds use their songs to communicate different messages to one another. People who study bird sounds are learning their meanings.

    Usually it is the male that sings. Early in spring he sings to say that he has picked out a piece of property. He sings to attract a female of his same kind. Together they will raise a family in his territory (领地). He sings to tell all other birds of his kind to keep out.

    Each kind of bird has its own type of song. Cardinals sing something that sounds a little like “What cheer, cheer, cheer.” Towhees sing, “Drink your tea.”

    Most of the time, birds pay attention only to the songs of birds of their own kind. Cardinals answer cardinals, and song sparrows answer song sparrows. A cardinal knows that a song sparrow will not try to steal its mate. So you can see one reason why a cardinal may chase away another cardinal but will not bother a song sparrow.

    Most different kinds of birds eat different things. To find enough to eat, a bird needs a big piece of land to search in. Many kinds of birds have some ways of dividing up the land into territories. Song sparrows, cardinals ovenbirds, and white-throated sparrows are some of the birds that have territorial systems.

    Especially in early spring, birds work out the boundaries between their territories by singing “keep out” threats and by chasing and fighting each other. The birds continue singing to tell females that they have set up territories. Neighboring birds seem to agree that there are make believe fences between their pieces of property. Then they do not have to waste energy chasing each other instead of taking care of their young.

    Scientists guessed that some birds could recognize their neighbors by small differences in their songs. Two scientists who studied white-throated sparrows found that these birds can even tell the difference between songs of individual birds of their own kind. White-throated sparrows have songs that seem to say “I'm your neighbor” or “I'm a stranger” or “I'm your neighbor to the west.” Other kinds of birds could tell neighbors from strangers by their songs, too.

    A heartbroken dog whose owner died two months ago is missing her so much that he attends services every day at the Italian church where her funeral was held, patiently waiting for her to return.

    Tommy, a seven-year-old dog, belonged to Maria Lochi, 57, and had been her faithful partner after she adopted him when she found him in fields close to her home. Mrs. Lochi adopted several dogs she found but friends said she developed a close friendship with Tommy and would walk to church with him every day, where he would be allowed to sit patiently by her feet.

    Father Panna said, “He's there every time I celebrate Mass and is very well behaved. He doesn't make a sound, and I've not heard one bark from him in all the time he has been in. He used to come with Maria and he was obviously devoted to her. I let him stay inside as he was always so well behaved and none of the other people ever complained to me. He's still coming to Mass even after Maria's funeral, he just sat there quietly. I didn't have the heart to throw him out. I've just recently lost my own dog so I leave him there until Mass finishes and then I let him out.”

    Tommy's been adopted by everyone in the village now and he is everybody's friend. Everyone looks out for him and leaves food for him, although it would be nice to find a proper home for him.

    The story of Tommy is similar to the 2009 Hollywood film Hachi which told of how a faithful Akita dog waits patiently for his master after he also dies. It was based on the true story of a Japanese Akita called Hachi, whose owner died in 1925 but for the next nine years he waited patiently at the railway station for his owner from where they regularly caught a train.

    Scotland has long been characterized as a land of romance. It contains ruins of many ancient castles and abbeys，and there is an attractive beauty in its mountains，long deep valleys，and ribbon lakes. Each year those things attract a great number of tourists.

    Numerous islands line the coast. In the north are two large groups，the Orkney Islands and the Shetland Islands. Close to the west coast are the Inner and Outer Hebrides groups，and the islands of Arran and Bute.

    The land may be divided into three regions: the Highlands in the north，the Central Lowlands and the Southern Uplands.

    The Highlands are wild and picturesque(如画的). A long valley called Glenmore crosses the Highlands from southwest to northeast.

    In the south of the Highlands are the Grampian Mountains，highest in the British Isles. Ben Nevis，the highest peak，rises to 1，243 meters. Ben Lomond rises from the shore of Loch Lomond，Scotland's largest freshwater lake.

    The Central Lowlands run from southwest to northeast and the greatest length is nearly 145 kilometers. The soil here is fertile，and there are four coalfields underlying the area. In the east is Edinburgh，Scotland's historic capital city，and in the west is Glasgow. Almost 90 percent of Scotland's population live in the Lowlands.

    In the Southern Uplands，the hills are generally less than 600 meters high. Their rounded or flat tops are often capped with dark peat(泥炭). Along the slopes are plants like grass and heather(石南花).

    Of course, she wasn't really my aunt and, out of fear, I never called her that to her face. I only referred to her as "My Aunt Fannie" because the name always made my father laugh quietly and gave my mother cause to look strictly at both of us—at me for being disrespectful of my elder and at my father for encouraging my bad behavior. I enjoyed both reactions so I looked for every opportunity to work the name into as many conversations as possible.

    As a young woman, my mother had worked in the kitchen of a large Victorian farmhouse. During those years my mother helped Aunt Fanny make the best blueberry jam ever tasted by anyone in Glenfield. She was well-known for her jam and for never sharing the recipe(食谱) with others. Even though my mother knew the recipe by heart, as long as Aunt Fannie was alive, she never made the jam without Aunt Fannie in our kitchen to direct the process and keep the secret.

    Each August, my mother would prepare me for Aunt Fannie's visit. One year, after I had helped with the jam process Aunt Fannie gave me a coin and then made me promise that I would never spend it. "Hold onto this coin," she said, "and someday you will be rich. I still have my very first coin, given to me by my grandmother." So I kept the coin in a small box and waited to become rich.

    I now have the blueberry jam recipe and the coin from Aunt Fannie. In people's eyes Aunt Fannie's success resulted from that secret recipe. But to me, it was just a common recipe. Neither have made me become a rich person, but I keep them as reminders to hold onto the valuable things in life. Money can make you feel rich for a while, but it is the relationships and the memories of time spent with friends and family that truly leave you wealthy. And that is a fortune that anyone can build.

    When we have troubles we turn to our family. But what would we do if we lost our family? I want to share with you a touching film about an Indian child who loses his loved ones.

    The main character in the 2016 Australian film Lion is a child named Saroo. When he is 6 years old, he follows his brother Guddu to a job, but gets lost. Saroo ends up in a new city and is adopted by a kind Australian family.

    However, one day Saroo is reminded of his original family. He knows immediately that he must find out as much about them as he can, so he racks his brains (绞尽脑汁)for all that he can remember.

    Lion is the most moving film that I have ever seen. When I saw the young Saroo trying to help his brother while they worked on a construction site at such a young age, I was amazed.

    In today's society，the poor are always looked down upon. But I saw in the eyes of young Saroo great courage and kindness that made me think differently. He has great qualities that help him survive in the strange city where he finds himself.

    When Saroo sees that people are kind he rewards them with the sweetest smiles and loves them with all of his heart. Saroo's goodness, I believe, allows him to live a happy life with his Australian foster (收养)family.

    It is unbelievably hard for Saroo to reunite with his original family. He can't even remember the name of his hometown. It takes him days to find the real one. In fact, he has to go through every alternative (供选择的东西)he can find on Google Maps.

I'm deeply impressed by Saroo's determination. It is why, when I saw the movie, I cried at the moment when he finally found his mother.

    Lion is full of moving and impressive details. There are so many that I can only mention a few of them here. But what stands out most to me is Saroo's commitment (投身)to finding his original family，and the fact that his search doesn't stop him from loving his foster family.

    I want to recommend this film to everyone. See it and you'll come to understand so much about family and love.

    In China we can see more African students in universities, which is a signal of a deeper China-Africa relationship, and the same trend is happening in Africa as well. Most Chinese students choose to study in universities in South Sudan, Egypt, Kenya, Ghana, Ethiopia and South Africa.

    There are three types of Chinese students in Africa. One type is language students who major in local African languages such as Swahili in China and go to African countries to study the language. Another type is non-language students who major in law, economy, culture, education or agriculture and go to African universities for six months to a year to learn more about the culture or for research. The above two types of students are all funded by Chinese government.

    A third type has been growing in recent years. More Chinese choose to develop their career and build a life in African countries, and some of their children tend to receive higher education in African countries. Some Chinese who work in Africa also further their study in their free time. Many Chinese choose to join the MBA program, since they work in a Chinese state-owned enterprise, and an MBA degree could help advance their career.

    In addition, as China and Africa's relations and cooperation are heating up and more Chinese companies and investors come to Africa under The Belt and Road Initiative(一带一路), more talents that understand Africa are needed. Besides, the new generations have more internationalized, curious attitudes, and are more willing to see and experience Africa themselves without any stereotypes(刻板印象), rather than just reading about it in a textbook.
