He's had a season of making headlines for his on court tantrums, but Nick Kyrgios showed his playful side 爱玩的一面 to deliver a classic moment of levity ( [ˈlevəti] a way of speaking or behaving that shows you. levitate [ˈlevɪˌteɪt] to rise and float in the air as if by magic, or to make something do this. ) during the International Tennis League in Dubai. Playing on the same team as Andy Murray, Kyrgios left the often surly ( unfriendly and rude. a waiter with a surly attitude. ) Scot in fits of laughter when he interrupted a post-match television interview to admire his hair. Murray had just led his Singapore Slammers team to victory over Roger Federer's UAE Royals when Kyrgios began carrying on off camera, causing the 28-year-old to pause and laugh. Opening up about his enjoyment playing in the event, Murray revealed how much he appreciated his younger teammate's company, telling the interviewer: "'Obviously you've got guys like Nick in the team, which makes it entertaining." Kyrgios responded by pretending to be star struck by the dual grand slam winner, prompting him to add: "He's been calling me God today. I don't know why but he has." The Aussie then snuck up from behind and began playfully caressing Murray's hair and face, sparking more laughter, before the interviewer asked: "What's going on here, you're just admiring Andy Murray?" Kyrgios then responded by hailing the former Wimbledon and US Open winner. "The whole team was looking forward to Andy joining and I think today was the Andy Murray show," he said. "We were all chatting last night and we put the faith in him and rode him all the way and he pulled through." Murray and Kyrgios have developed a close bond since the Canberra star burst onto the ATP tour, with the Scot leaping to the 20-year-old's defence earlier this year when he was criticised for his temperamental on court antics. Murray himself was derided for boorish behaviour ([ˈburɪʃ] rude and not caring about other people's feelings. his boorish behavior.) early in his career and Australian tennis fans will be hoping his influence rubs off on Kyrgios and translates to grand slam success. 4. wave and pay a system of paying for small purchases by moving a credit card or mobile device in front of a special machine which automatically reads the information.

Rip Curl, which sponsors Fanning, confirmed that Peter had passed away. "This is a sad and unfortunate incident and is a private matter for the family to deal with," a Rip Curl spokesperson told the ABC. "We ask that the media respect their privacy. But we can confirm Mick's older brother Peter has sadly passed away. We will not be commenting further." "The WSL, The World Surf League, which is the governing body 管理机构 for professional surfers, are aware of the reports but have not heard from the Fanning camp regarding them so we're in no position to comment," it said in a statement. Fanning won his round-three heat against Pipeline specialist Jamie O'Brien. In an interview after that heat, earlier in the day, he made no mention of the reported tragedy. "Jamie is probably the best guy out here, he surfs it the most, so I knew it was always going to be tough," Fanning said. "I just got lucky at the start ... and kept trying to improve that score and go from there." Last week, Fanning was among a group of surfers who helped bring young American Evan Geiselman out of the water at the famed Pipeline break.

play chicken 逞强斗狠, 逞勇, 斗鸡游戏 slang to play dangerous games in order to discover who is the bravest. The game of chicken (also referred to as playing chicken) is a "game" in which two players engage in an activity that will result in serious harm unless one of them backs down. It is commonly applied to the use of motor vehicles whereby each drives a vehicle of some sort towards the other, and the first to swerve 躲开, 闪开 loses and is humiliated as the "chicken". (An example of this can be seen in the movie Rebel Without a Cause, in which two characters drive towards a cliff.) In practice, this sort of game, if played at all, is most likely to be played amongst adolescents or aggressive young men, though it is not at all popular. The principle of the game is to create pressure until one person backs down. The phrase game of chicken may also be used as a metaphor for a situation where two parties engage in a showdown where they have nothing to gain, and only pride stops them from backing down. Bertrand Russell famously compared the game of chicken to nuclear brinkmanship(Brinkmanship (also brinksmanship) is the practice of trying to achieve an advantageous outcome by pushing dangerous events to the brink of active conflict. It occurs in international politics, foreign policy, labour relations, and (in contemporary settings) military strategy involving the threat of nuclear weapons, and high-stakes litigation. This maneuver of pushing a situation with the opponent to the brink succeeds by forcing the opponent to back down and make concessions 认输. This might be achieved through diplomatic maneuvers by creating the impression that one is willing to use extreme methods rather than concede. During the Cold War, the threat of nuclear force was often used as such an escalating measure. Brinkmanship is a term coined during the Cold War to describe the tactic of seeming to approach the verge of war in order to persuade one's opposition to retreat退缩. It was an effective tactic because neither side of a conflict could contemplate mutually assured destruction in a nuclear war, acting as a nuclear deterrence 核威慑 for both the side threatening to pose damage and the country on the 'receiving end'. Ultimately, it worsened the relationship between the USSR and the US.), a method of negotiation in which each party delays making concessions until the deadline is imminent. The psychological pressure may force a negotiator to concede to avoid a negative outcome. It can be a very dangerous tactic; if neither party "swerves", a "crash" is certain to occur. Melbourne cabbie spits in Uber passenger's face: A Melbourne Uber passenger who was verbally abused by a Silver Top taxi driver before he wrenched open her car door and spat in her face says she plans to press charges over the alleged assault. The 25-year-old woman, who wishes to be identified only as "Nellie", says the taxi driver's aggression was not provoked and that the incident, which happened on Nicholson Street around 8:30pm last night, left her shaken. "He started yelling 'f---ing' Uber drivers', 'f---ing get off the road', and I just kind of had a chuckle with the driver and we moved on," Nellie told ninemsn, explaining that she suspects the cabbie identified the Uber driver by his GPS rig. "Then we kind of went back and forth – he was driving next to us, and then we stopped at the lights and I took a photo of his numberplate, cos I'm like, 'that's not okay, you can't keep on yelling stuff at us'," she said. That's when things escalated. As Nellie's video shows, the cabbie got out of his car – despite the fact that the light was green – and approached the Uber vehicle. "When he came up to the window, I was like, 'oh my God – is he gonna hit me or grab my phone and smash it or something?'" As the footage shows, the cabbie proceeded to open Nellie's door and spit in her face. But while the video, shared on Reddit and YouTube this morning, bears out Nellie's version of events (bear out 证实, 支持 to show that something is true or that someone is telling the truth. Scientific evidence bears out the claim that stress and disease are linked. I always said – and Rick will bear me out 有...为证, 可以作证 – that this wouldn't work.), a police officer told Nellie that her chances in court could be affected by the fact that Uber is illegal in Victoria. That seems pretty rich to the insurance rep, who considers herself "thick-skinned" but was still badly jolted 惊吓过度, 惊吓到 by ( jolt I.

宣传噱头: An Irish backpacker has shocked his parents into a flurry of expletives by Skyping them as he jumped out of a plane in Sydney. Roger Ryan gave no warning he was skydiving when he started the video call to his mum and dad back home. "I'll talk to you in a second I'm just going to get this out of the way 做完, 完事(get something out of the way to finish doing something, especially something difficult or unpleasant. I can't wait to get all this housework out of the way. I like to get my homework out of the way on a Friday night so that I can enjoy the weekend.

The pair swear in disbelief as they suddenly realise what they're witnessing. "He's doing a selfie coming down in the f---ing airplane," Mr Ryan's father says. His mother screams and takes a photo of the screen as the backpacker plummets towards the ground while keeping the camera fixed firmly 牢牢的 on himself. The footage was published on YouTube by hostel booking site Hostelworld after they approached backpackers at Sydney's Bounce Hostel and offered them the chance to go skydiving with a twist. 明星新恋情: It was just over two months ago that she announced her separation from longtime husband Brad Miller. But it looks like Pia Miller is already back in the saddle ( back in the saddle 回归, 回来了 doing something you stopped doing for a period of time Friedman's career seemed to be finished a month ago, but he's back in the saddle and playing for Houston. ) after being spotted shopping in Sydney on Thursday with Tyson Mullane.

It's true – some people hate the gym. But a new fitness trend 健身趋势 has hit the scene in a big way, and all you need is your bodyweight and a bar. The re-birth of calisthenics: Traditionally known as calisthenics( callisthenics = calisthenics [ˌkælɪsˈθenɪks] exercises that you do without special equipment to make your body stronger, thinner, and more healthy. Calisthenics are a form of exercise that consist of a variety of gross motor movements, often rhythmical, generally without using equipment or apparatus 器具, thus in all essence body-weight training. Thus making them different from High-Intensity Anaerobic training such as CrossFit and P90X and generally safer. They are intended to increase body strength, body fitness and flexibility through movements such as pulling or pushing yourself up, bending, jumping, or swinging, using only one's body weight for resistance. They are usually conducted in concert with stretches ( in concert performing music or songs in a concert. an opportunity to see Leila Josefovicz in concert. in concert (with someone) 联合, 协同, 结合 together. jointly. if two or more people do something in concert, they do it together. acting jointly. "We must take action in concert with our European partners". The buyout was planned by a number of companies acting in concert. ).

II. biology using oxygen. aerobic bacteria. aerobic respiration the process by which the body uses oxygen in order to make food separate into the substances it consists of and produce energy. ), in addition to improving psychomotor skills such as balance, agility敏捷灵活 and coordination协调性. Groups such as sports teams and military units often perform leader-directed group calisthenics as a form of synchronized physical training (often including a customized "call and response" routine) to increase group cohesion and discipline. Calisthenics are also popular as a component of physical education in primary and secondary schools over much of the globe. ), bodyweight-only training has seen resurgence 复兴, 回顾, 重新流行, 流行回来 in the fitness marketplace as people become more interested in mobility, functional movement and gymnastics. And it's not just marketing spin. A study from 2013 found that a high-intensity 高强度的 circuit using bodyweight only moves delivers numerous health benefits, including your ability to stack on muscle. So you can you get ripped without laying a finger on a weight? Marcus Bondi, part of a team that claims Guinness World Records for strength such as most consecutive muscle-ups, says yes – and his body is proof. "Combined with strategic nutrition, bodyweight training can give you the strength, stamina, sixpack abs and muscle definition you have always wanted," Marcus told ninemsn Coach. "Bodyweight training unites elements of gymnastics, compound bodyweight exercises, calisthenics, strength training, parkour ( Parkour [pɑ:ˈkuə] 跑酷, 纵横跳跃 is a training discipline using movement that developed from military obstacle course training. Practitioners aim to get from one point to another in a complex environment, without assistive equipment and in the fastest and most efficient way possible. Parkour includes running, climbing, swinging, vaulting, jumping, rolling, quadrupedal movement, and other movements as deemed most suitable for the situation. Parkour's development from military training gives it some aspects of a non-combative martial art. Parkour is an activity that can be practiced alone or with others, and is usually—but not exclusively—carried out in urban spaces. Parkour involves seeing one's environment in a new way, and imagining the potentialities for navigating it by movement around, across, through, over and under its features. ), army boot camp, free-running and yoga," says Marcus. "The bonus of bodyweight training is that it uses many compound exercises, which optimise complete muscle exertion in unison." You're less likely to injure yourself. It's the total-body nature of calisthenics that Marcus believes is the key to packing on kilos of lean muscle with a relatively low risk of injury. "When doing bodyweight training all of your muscles, tendons and joints develop strength relative to each other, maximising power and strength while minimising the risk of injury." Stan Veniaminov, founder of the Bondi Beach Bar Brutes (BBBB), believes that one of the upsides of bodyweight training is that anybody of any age can do it. "Everyone should practice calisthenics, men, woman of all ages. It's functional, challenging and rewarding type of exercise mentally and physically," Veniaminov told ninemsn Coach. "It's fun because the possibilities are endless when you try new movements that require strength, mobility and explosive power." If you're still doubtful that calisthenics can help you chisel out the body of your dreams, just check some of the rigs on the lads from the BBBB: Three of the best bang-for-your-buck 经济实用的 bodyweight exercises: Chin ups. They've long been called the "squats for the upperbody" because chin-ups allow you to recruit and build an enormous range of muscles including your lats, biceps, shoulders and traps. Research has found that the chin-up utilises more of your biceps than a pull-up, making it perfect for building those sleeve-busting guns. A chin up is where your palms face away from your body, whereas a pullup has you palms facing towards your body. Marcus has his own way of supercharging the movement: "To really ratchet things up ( [ˈrætʃɪt] n. a part of a machine consisting of a wheel or bar with teeth on it. Another metal piece fits into it, allowing it to move in only one direction. v. to increase or decrease by small amounts during a period of time, or to make something do this. We are taking steps to ratchet up our profit margin. Ratchet (device) 限制单向转动的齿轮装置, a mechanical device that allows movement in only one direction. A ratchet is a mechanical device that allows continuous linear or rotary motion in only one direction while preventing motion in the opposite direction. Ratchets are widely used in machinery and tools. Ratchet 一种扳手, a tool also known as a socket wrench. A socket wrench is a type of wrench that has a socket attached at one end, usually used to turn a fastener. The most prevalent form is the ratcheting socket wrench, often called a ratchet. A ratchet is a hand tool in which a metal handle is attached to a ratcheting mechanism, which attaches to a socket, which in turn fits onto a type of bolt or nut. Pulled or pushed in one direction, the ratchet loosens or tightens the bolt or nut attached to the socket. Turned the other direction, the ratchet does not turn the socket but allows the ratchet handle to be re-positioned for another turn while staying attached to the bolt or nut. This ratcheting action allows the fastener to be rapidly tightened or loosened in small increments without disconnecting the tool from the fastener. A switch is built into the ratchet head that allows the user to apply the ratcheting action in either direction, as needed, to tighten or loosen a fastener. Other common methods of driving socket wrenches include pneumatic impact wrenches, hydraulic torque wrenches, torque multipliers and breaker bars. Some lesser known hybrid drivers include striking wrench tools with square drive, and hydraulic impact wrenches (typically powered by on site hydraulic power such as present with military tanks, and many rail car applications).), rolled-up towels and old ropes are hung over bars will extract maximum burn from every available muscle fibre!" Human flags. A human flag is exactly what it sounds like – you hold on to a vertical pole, extend your legs and hold yourself parallel to the ground. If you thought your abs were strong, just give one of these a go, says Al Kavadlo in an article for T-Nation. "The first time I attempted the human flag, I didn't come close to staying up for even a second, and I was nearly 30 years old and had been working out for most of my life," says Kavadlo. Front levers. A front lever is a true test of your core strength and your conditioning – you'll find out pretty quickly if you're carrying any extra flab. Logan Christopher, a renowned calisthenics coach, wrote in an article for Breaking Muscle that the front lever makes or breaks people. "More than likely, if you can do a front lever you'll have a great sixpack. This isn't just because you'll have strong abs, but the less bodyweight you have the easier this will be," writes Christopher.
