Two weeks ago, Ray Johnstone, an elderly man living alone in South Australia, posted a classified advertisement in search of a friend. Specifically, he was on the hunt for a fishing partner, as he no longer had anyone to share his hobby with. “I'm a widowed retired man who is looking for a fishing mate,” he wrote on Gumtree, “My previous fishing mate is now deceased. He will never accompany me to go fishing. I am a land-based fisherman. I have all the gear for all types of fish that is required for land-based fishing.”

    Like all of us, 22-year-old Mati Batsinilas was touched by the man's advertisement, so he reached out to him and arranged an outing. Rather than simply spend the day with Johnstone somewhere local, however, he and his family offered to take him on an all-inclusive weekend fishing trip of Stradbroke Island in Queensland. And, as expected, they had a good time. “Whilst on the island we covered four-wheel driving, site-seeing, fishing, swimming, chats with the locals and the best of all... just relaxing and chatting like mates,” Batsinilas wrote in a Facebook post. “Once you reach a level of maturity in life, age should only be a number. My respect for Johostone is obviously very high, but I treated him exactly the way I would have treated one of my 22-year-old mates.”

    Fortunately, it sounds like Johnstone won't have to place more classified advertisements any time soon. In addition to finding a friend, the pensioner has become a star on the Internet, with many social media users voicing their interests in meeting the now-famous fisherman.

    Careers in zoology are extremely varied and unique, and can provide incredible learning and work opportunities for anyone devoted to animal studies and welfare. Zoology, or the study of animals, is a wide field with many specialties, including research, conservation, veterinary (兽医的) medicine, and the care of animals. For people with a love of animals and some training, dreams of careers in zoology may come true.

    Some careers in zoology focus on research and scientific studies. These careers may allow those with a good theoretical science background to develop and run studies that improve human understanding of the animal world. Research in zoology can help create safer and more effective products for animals or can teach humans more about animal behavior in order to aid in conservation, breeding programs, and habitat preservation.

    Careers in zoology that focus on conservation attach great importance to the continued survival and increased protection of animal species. Conservationists may work with political groups or governments to help make laws to protect and preserve animals, or may work in the field gathering information on potential threats to the health of global ecosystems. Some conservationists work in educational fields, trying to improve human efforts to save animals from extinction.

    Animals are subject to illness and injury, and some careers in zoology help to create a safe, stable animal population. Veterinary medicine is an important specialty field, and may take several years of intensive training to qualify as a certified veterinarian. While many veterinarians focus on the small-animal practice of domestic pets, vets in rural areas often work with large farm animals and more adventurous veterinarians may work with exotic species in zoos and wildlife preserves. .

    Humans love to observe animals, and modern-day zoos and wildlife preserves help meet that interest while providing facilities to assist with conservation programs. Zoology careers in zoos can range from overseeing breeding programs, to creating the proper diet for a deer, to cleaning the tiger's cage. Many volunteer and entry-level jobs are available for people that love animals.

    Bullying(霸凌) can take a variety of forms, from the verbal to the physical as well as indirect forms, such as being excluded from social groups. Bullying is clearly unpleasant, and can make the child experiencing it feel unworthy and depressed. In extreme cases it can even lead to suicide, though this is thankfully rare.

    Until recently, not much was known about the topic, and little help was available to teachers to deal with bullying. Perhaps as a consequence, schools would often deny the problem. There is no bullying at this school' has been a common answer if asked, almost certainly untrue. Fortunately more schools are now saying: “There is not much bullying here, but when it occurs we have a clear policy for dealing with it.” Three factors are involved in this change. First is an awareness of the severity of the problem. Second, a number of resources to help tackle bullying have become available in Britain. For example, the Scottish Council for Research in Education produced a package of materials, Action Against Bullying, circulated to all schools in England and Wales as well as in Scotland. In Ireland, Guidelines on Countering Bullying Behaviour in Post-Primary Schools was published, too. Third, there is evidence that these materials work, and that schools can achieve something.

    Evidence suggests that a key step is to develop a policy on bullying, saying clearly what bullying means, and giving explicit guidelines on what will be done if it occurs, what records will be kept, who will be informed and what punishments will be employed. The policy should be developed through consultation over a period of time. Pupils, parents and staff should feel they have been involved in the policy. Other actions can be taken to back up the policy. There are ways of dealing with the topic through the curriculum, using video, drama and literature. But curriculum work alone may only have short-term effects; it should be an addition to policy work. There are also ways of working with individual pupils, or in small groups. Work in the playground is important, too. One helpful step is to train lunchtime supervisors to distinguish bullying from playful fighting, and help them break up conflicts. Another possibility is to improve the playground environment, so that pupils are less likely to be led into bullying from boredom or frustration.

    With these developments, schools can expect that at least the most serious kinds of bullying can largely be prevented. The more effort is put in and the wider the whole school is involved, the more substantial the results are likely to be. The reduction in bullying and the consequent improvement in pupil happiness is surely a worthwhile objective.

    In the early hours of the morning, Gary Miller was in his truck, traveling down the road alone to deliver. Everything seemed calm. But with the sound of a fire siren (警笛) cutting through the wind, he became alarmed. Miller, a trucker by trade, has been a volunteer firefighter for 40 years. That loud, sharp siren assured him that help was on the way.

    Most people never realize that this help is often a crew of volunteer firefighters. They make up 70 percent of the country's nearly 1.2 million firefighters. "When I was a teenager there would be many who responded. About 20 people were coming into the voluntary fire station at one siren." Miller laughed. But now, at his 54, that memory is almost ironic (讽刺的)to him. When a call comes in, his station might get only three or four people responding. He said: "People don't want to, or rather, they don't have time to volunteer." Adults' burdens have become greater. There isn't as much time left for volunteering when most people rely on a two-income household now more than ever.

    Firefighters face far more than what we imagine. The emotional stress on a firefighter stands out. "We're asked to help someone at their most vulnerable (易受伤的) time. But we can't always save the day like we hope to." Miller reflected on the case years ago. "A mother's car was hit hard, and she had two children in the backseat." By the time he arrived on the scene, there wasn't much to be done. "One child died in my arms and I felt so defeated."

    Along with the emotional stress, the physical danger is just as great. Even with the progress of equipment and new training, that's still not always enough to save a firefighter's life. In 2016, 60 firefighters died in the line of the duty. "When you respond, you never know if it is to be your last," Miller said. "And that's just a risk we take." Miller continued. "It's dangerous. But it's also the most rewarding thing I've ever done."

In the movie, The Day After Tomorrow, many climate changes including an ice age are caused by global warming. Much of the science in the movie has been questioned by people. However, there may be some truth to the idea in the movie that global warming could cause an ice age.

The theory starts with an understanding of why Europe and Scandinavia are not colder already. After all, other places at the same latitude(纬度) are covered with ice. The ocean current called the Gulf Stream brings warm waters from the Caribbean to the UK and Europe. These waters warm the countries around their path. This is why the UK, Europe and Scandinavia have a warmer climate than Alaska. Global warming has nothing to do with this. Global warming is significant. It could slow the Gulf Stream, or even stop it. If this were to happen, the cold waters would stay in the area of Europe, the UK, Scandinavia and the Northeastern US. It could mean an ice age for those regions.

Some weaknesses in the Gulf Stream could happen for different reasons. These days, it could happen due to global warming, caused by human activities, such as the burning of fossil fuels.

If a new ice age happened, it would probably be caused by the melting of the polar ice. This will lead large quantities of cold and fresh water to come into the ocean, which would disrupt the Gulf Stream and cause the cooling of many areas that now have a mild climate.

Scientists have gathered a lot of data from the oceans and the land to try to determine whether an ice age could be caused by global warming. With all this information at hand, it appears that it is indeed possible that global warming could lead to an ice age.

"Having the world at our fingertips" is a metaphor often used when we put our hands on information technology, like smartphones and computers. This is a good metaphor. But what is much better is how we use our hands to make things done.

Put one hand flat on a surface, palm down, and you might be able to make out the outline of 14 short bones in your thumb and fingers, in addition to 5 longer ones in your palm that are jointed to your wrist. These bones give each hand its rigid, knuckled structure. Together they're critical components of the anatomical （解剖的） architecture that allows your hand to move. At each of your fingertips there's an ever-growing, translucent plate of fibrous protein, otherwise known as a nail. Although they're nice for decoration, your nails protect and enhance your sensitivity to touch, too.

Imagine squeezing a piece of paper between your thumb and index finger, for example. We use this type of forceful pad-to-pad precision grasping without thinking about it, and literally in no time. Yet it was a breakthrough in human evolution. Other primates （灵长目动物） exhibit some kinds of precision grasps in the handling and use of objects, but not with the kind of efficiency that our hand does.

With a unique combination of traits, the human hand shaped history. No question, stone tools couldn't have become a keystone of human technology without hands that could do the job, along with a nervous （神经的） system that could regulate and coordinate the necessary signals. Even for those who have never attempted to make a spear tip or arrowhead from a rock, it's obvious that it would require strong grasps, constant rotation and repositioning, careful strikes with another hard object. And even for those who have done so, it can be a bloody business.

Of course, the most common object that people touch nowadays is a screen. And the tap-tap-tap movement of our fingers is a unique human ability, as no other primate can move their fingers as rapidly and independently as we do. Here again, we can thank the extraordinary human brain given that normal finger tapping requires the functional integrity of different parts of our central nervous system.
