2 . For sports fans, there's nothing better than watching a live event on TV or at a sports venue（场地）. But there's nothing worse than that event being called off because of bad weather. Bad light, a waterlogged pitch （场地）or excessive heat can cause matches to be postponed. But according to the latest research, extreme weather might be disrupting （打乱） the sporting calendar more than ever in the future.

In one sport, golf, major tournaments like The Open, are already predicted to be victims of our changing climate. In the UK, an organization called The Climate Coalition says that golf courses such as St Andrews could be under water by the end of the century if sea levels rise even slightly. It told the BBC that its research predicts ^u cancelled football matches, flooded cricket grounds and golf courses crumbling into the sea.”

The threat to sporting fixtures （体育赛事）from climate change has been further highlighted in a new report, commissioned by the Rapid Transition Alliance. Writing about this for the BBC, Matt McGrath says that ”By 2050, it's estimated that almost one in four English football league grounds can expect flooding every year." This will mean fewer matches played, less opportunity to watch the beautiful game and reduced revenue （收入） from ticket sales.

Cricket also faces huge challenges globally as temperatures rise in places like India, Australia and the West Indies. The report says that stadiums in Adelaide and Perth will see a 60% increase in days with temperatures over 40°C over the next decade.

Of course, we know that the solution lies with reducing our carbon footprint. We could travel less to attend sports events, and reduce our waste when we do go. But this latest report finds that sports leaders are generally failing to address the issue seriously. However, because sport is universally popular and can be very influential, maybe it should be players, teams and their sponsors who promote a carbon-neutral message to help protect sporting venues - before it's ‘ game over’.

3 . Are you the type to run before breakfast in a morning? Working out on an empty stomach won't hurt you ——and it may actually help, depending on your goal.

Exercising before eating comes with the risk of feeling light-headed due to low blood sugar. You might feel tired or uneasy, and won't be able to work out as enthusiastically as you would have. A light amount of food is important for older adults over 55 to eat something before exercising — especially in the morning. But if your primary exercise goal is weight loss, exercising on an empty stomach may come with some promising benefits. There's some research to support the idea that working out in a fasted （禁食的）state can burn more fat than exercising in a fed state.

Working out on an empty stomach, however, may also not prove true for everyone. “Some people advocate for lasted exercise, but these people tend to be young and in amazing physical - shape,” says Douglas Paddon-Jones, a muscle physiology researcher and a professor of aging and health at the University of Texas Medical Branch. “They have no health problems, and what they're eating is super-high quality and carefully regulated.” On the other hand, working out in a fasted state without proper planning or professional oversight may run the risk of unhealthy body composition changes.       

For people who aren't athletes, fueling up with food before a workout may be the best way to get the most fat-burning benefit. “You don't want to fill up； you just want to give your body a burst of energy to power your training period. After you exercise, drink some water ——but wait 60 to 90 minutes before eating, ”says Shivani Sahni, director of the nutrition program at Harvard University's Instituted for Aging Research. “You're trying to take advantage of your promoted metabolic （新陈代谢）rate post-exercise, so if you can go an hour or an hour and a half without eating, you'll maximize the fat-burning response,” says she.
