And here's why.会的!来看看为什么吧。The bit of sunlight that causes damage to your skin is called ultraviolet radiation, or UV.阳光中会对皮肤造成伤害的部分叫做 “紫外线(UV)辐射”。It's measured on a scale from 1 to 11+, and it's usually strongest between late morning and early afternoon.紫外线的强度被划分为从 1 到 11+ 的不同等级,通常上午晚些时候到下午早些时候之间的紫外线强度最高。In places near the equator, UV levels can be high all year.赤道附近地区的紫外线强度可能全年都很高。(Source: US Environmental Protection Agency)Almost 90% of UV can pass through scattered clouds, so a grey day can still be risky.(信息来源:美国国家环境保护局)近 90% 的紫外线都能穿透松散的云层,因此阴天时依然有被紫外线晒伤的风险。We need UV for our body to make Vitamin D, which is important for the function of bones, blood cells and our immune system. 我们的身体需要紫外线来合成维生素D,这种维生素对我们维持骨骼、血细胞和免疫系统的功能至关重要。But too much UV could cause sunburn, skin ageing, and increase our risk of skin cancer.但过量的紫外线会引起晒伤和皮肤老化,并且增加皮肤癌的风险。(Source: World Health Organisation)In 2022, over 1.5 million people were diagnosed with skin cancer worldwide.(信息来源:世界卫生组织)2022 年,全球有超过 150 万人被确诊患有皮肤癌。The World Health Organisation recommends taking extra precautions when UV levels are at 3 or above.世界卫生组织建议,当紫外线指数等级在3级以上时应采取额外的防护措施。Tips include wearing protective clothing, using at least SPF 30 sunscreen and reapplying every two hours.建议包括穿戴防护性的服装和使用防晒指数(SPF)在 30 及以上的防晒霜,并每隔两个小时重新涂抹一次防晒霜。Try to avoid midday sun, use shades wisely, and don't forget sunglasses – UV rays can cause eye damage too.尽量避开正午的阳光、合理使用遮光物并且不要忘了戴太阳镜——紫外线照射也会导致视力受损。

Five chunks of chocolate history 五 “块” 有关巧克力的历史
英语大破解Five chunks of chocolate history 五 “块” 有关巧克力的历史你的浏览器不支持音频元素.本集内容Five chunks of chocolate history 五 “块” 有关巧克力的历史文字稿Did you know cocoa was once mistaken for animal poo?你知道吗,可可豆曾被误认为是动物粪便?Here's five chunks of chocolate history.来看一看五 “块” 有关巧克力的历史。1. Origins起源3,000 years ago, the ancient Maya and Aztec people of what is now Mexico in Central America believed it was a sacred drink from God and used cocoa beans as currency.三千年前,曾经定居在现在中美洲墨西哥地区的古代玛雅人和阿兹特克人认为可可是上天赐予的一种神圣饮品,并将可可豆作为货币使用。2. Global popularity风靡全球In the 1500s, Spanish explorers took the beans back to Europe, but it was an expensive luxury. 16 世纪,西班牙的探险家们将可可豆带回欧洲,但它在当时是一种昂贵的奢侈品。The first batch to arrive in Britain was burnt, after the beans got mistaken for sheep poo.第一批运抵英国的可可豆被烧毁了,因为被误认为是羊粪。Later, chocolate bars were developed. It got cheaper, so more people could afford it.后来,人们研发出了巧克力棒。巧克力价格便宜了,所以更多的人也能买得起了。3. Health对健康的好处Some experts say dark chocolate is the best form to eat, as it's full of compounds called flavonoids. It's thought that small amounts can help your blood sugar, heart and brain. 一些专家认为,相对其它巧克力种类来说,黑巧克力的健康好处最多,因为它富含一种叫作类黄酮的化合物。人们认为吃少量的黑巧克力有助于控制血糖,促进心脏和大脑的健康。White chocolate was accidentally invented when doctors were trying to get children to drink more milk.白巧克力是个意外的发明,当时医生通过给牛奶里添加其它成份而试图让医院里的孩子们多喝牛奶。4. Exploitation劳动剥削But chocolate has a difficult past, too. Cocoa plantations have historical links to slavery.但巧克力也有一段艰难的过去。可可种植园与奴隶制有深远的历史联系。5. Environment环境影响(Source: World Cocoa Foundation)Some organisations say forests are being cut down to make way for cocoa plantations.(信息来源:世界可可基金会)一些相关组织表示,森林正在遭到砍伐,以为种植可可树腾出土地。And an increasing climate crisis means less cocoa is being produced, so the price of your favourite treat could be going up.同时,气候危机的加剧意味着可可豆产量减少,所以你爱吃的巧克力价格可能也因此上涨。

Well, quite possibly freedom.目的地?很可能是自由。Tracey Twomey, Keeper, Newquay Zoo"Bye-bye Kitten!"特蕾西·图米,纽基动物园饲养员“再见了,基滕!”This is where it's hoped Kitten will end up – the Black Forest in southwestern Germany, where there's already a small population of wild lynx.研究人员希望这里能成为基滕最终的家园——德国西南部的黑森林地区,这里已经有一小群野生猞猁。After a journey of more than 800 miles, Kitten emerged into a special enclosure near the forest, where she will be closely monitored.在经过了 800 多英里的旅程后,基滕钻出箱子,进入了黑森林附近的一片特殊围场中,在这里她将受到密切监测。Jonah Fisher, BBC Correspondent"Everyone expects this lynx to be able to hunt and kill the food it needs to survive in the wild. That comes naturally to cats. The big question is, after spending all of its life up to now, looking at people through bars, whether it can learn to be scared of humans to avoid them."约拿·费舍尔,BBC 通讯员“所有人都期待着这只猞猁能捕获并猎杀她在野外生存所需要的食物。这对于猫科动物来说是天生的能力。但最大的问题是,到目前为止,基滕的生活是从栅栏里观察人类,它是否还能学会惧怕并避开人类。”Watching on at Newquay as the lynx strode out, Tracey, her keeper.这位在纽基看着这只猞猁大步离开箱子的人是她的饲养员特蕾西。Tracey Twomey, Keeper, Newquay Zoo"I didn't think I'd get emotional. But yeah, just seeing her take that step out, this is a dream. This is the real conservation work that we want to be able to do."特蕾西·图米,纽基动物园饲养员“我以为我不会情绪激动。但看着她迈出那一步简直就像是做梦一样。这正是真正的、我们想要做的动物保护工作。”If all goes according to plan, Kitten will become the first British cat to go from a zoo to living in the wild.如果一切都能按计划进行的话,基滕将成为第一只回归野外的由英国繁育出的猫科动物。

The short answer is yes.(来源:BBC Future)你有没有想过用你的水瓶喝水会让它变脏?简单来说确实如此。(Source: H. Liu and Q. Liu, 2017, Annals of Civil and Environmental Engineering)With each sip from your water bottle, you introduce more bacteria to it, which can then multiply by the millions within a day.(来源:H. Liu and Q. Liu, 2017, Annals of Civil and Environmental Engineering)每从水瓶里喝一口水,你就会向水瓶中带入更多的细菌,这些细菌在一天内会繁殖数百万。Dr Primrose Freestone from the University of Leicester warns that using the same water bottle for different kinds of drinks will also stimulate the growth of microbes.莱斯特大学的普里姆罗斯·弗利斯通博士提醒称,用同一个水瓶装不同种类的饮品也会促进微生物的繁殖。Even when you leave it aside, the bacteria will still grow over time if there's water in the bottle.即使你把水瓶放在一边不使用它,细菌也会随着时间逐渐繁殖,只要水瓶中有水。(Source: The University of Alabama at Birmingham)Although most microbes aren't harmful to humans, some can cause infections or trigger symptoms. For example, mould found in water bottles can lead to respiratory problems, especially with people who have allergies.(来源:阿拉巴马大学伯明翰分校)虽然大多数微生物对人类无害,但一些微生物会导致感染或引发病征。比如,水瓶中发现的霉菌可能引发呼吸系统问题,尤其是对于有过敏症状的人来说。So, how can we take care of our water bottles?那么,我们应该如何清洁自己的水瓶呢?Experts suggest that we should clean our bottles several times a week if we use them regularly.专家建议我们应该每周都清洗几次水瓶,如果我们经常使用它的话。For the best result, use hot water and washing-up liquid when cleaning your bottle. Then, use a brush to clean the inside of the bottle, and leave it for ten minutes before rinsing it with hot water again. Lastly, allow the bottle to air-dry instead of wiping away the water residue.要达到最佳的清洗效果,应使用热水和洗洁精清洗水瓶。先用刷子清洁瓶子内部,接着静置十分钟,然后再用热水冲净。最后,让水瓶自然晾干而不是擦干残留的积水。And remember, if your water bottle starts to smell bad even after washing, it might be a good idea to switch it for a new one.还要记住的是,如果你的水瓶在清洗之后依然闻起来有异味,那换个新水壶不失为一个好主意。

Some people claim it helps with any number of things from glowing skin to weight loss, and are flocking to buy it in gels, gummies, powders and capsules.海藻仅是又一个健康饮食热潮吗?一些人称海藻具有许多功效,比如能使人的皮肤焕发光彩或减轻体重,并且争先恐后地购买海藻制成的凝胶、软糖、粉末和胶囊。Sometimes called Irish moss, sea moss is a red seaweed found mostly along the Atlantic coasts.这种海藻也被称为 “爱尔兰海藻”,它是一种红色的海藻,主要生长在大西洋沿岸。People have been harvesting it for centuries. It's commonly used as a thickener and gelling agent in processed foods like ice cream and chocolate milk.几个世纪以来人们一直在采收这种海藻。它被作为一种增稠剂和胶凝剂而广泛应用于加工食品中,比如冰激凌和巧克力奶。Sea moss is packed with good stuff like iron, magnesium, fibre, and vitamins including A and C.海藻富含多种有益成分,如铁、镁、纤维以及多种维生素,包括维生素 A 和维生素 C。But nutritionists say there's little evidence to suggest sea moss should be called a superfood.但营养学家表示,现有的证据很难证明海藻可以被称为一种超级食物。Some early research has been done. One study on rats found that sea moss helps increase beneficial gut bacteria. But more testing is needed on humans.科学家已经完成了一些对海藻的初步研究。一项在老鼠身上进行的研究发现海藻能帮助提升老鼠肠道益生菌的数量。但要得出结论尚需更多的人体试验。There are a few risks too – sea moss has high levels of iodine, which can cause thyroid problems if you have too much, especially for pregnant women or elderly people. 食用海藻也会带来一些健康风险。海藻含有大量的碘,而食用过多的碘可能会引起甲状腺问题,特别是对孕妇和老年人来说。And like other seaweed, it can also absorb small amounts of heavy metals from the water depending on where it grows.并且和其它海藻一样,这种海藻也会从生长环境中吸收少量的重金属。That could include arsenic, mercury, or lead, which might be harmful if they build up in your body over time.其中可能包括砷、汞或铅,这些元素如果长期在体内积累就可能会对健康造成损害。The advice from health professionals – sea moss is generally fine to eat for most people, but it shouldn't replace a varied diet.来自健康专业人士的建议是,大多数人通常可以正常食用海藻,但它不应取代多样化的饮食结构。

And, they ate about 100 fewer calories' worth of snacks three hours later.(来源:布里斯托大学)在一个小规模研究中,用 24 分钟吃完一顿饭的人比用六分钟吃完同一顿饭的人饱腹感更强,血液中控制饥饿的荷尔蒙胃促生长素的含量也更低。并且,他们也比吃得快的人在用餐三小时后少吃了热量为 100 卡路里的零食。(Source: Hunan Normal University, China; University of Manitoba, Canada)Studies have also linked fast eating with higher rates of belly fat, blood pressure, and metabolic problems like type 2 diabetes.(来源:湖南师范大学;曼尼托巴大学)研究还发现,腹部脂肪多、血压高,以及患2型糖尿病等代谢问题的概率高也和吃东西速度快有关。(Source: Kyoto Women's University, Japan)A small Japanese study found higher peaks of blood sugar in healthy women who took 10 minutes to eat a meal instead of 20.(来源:京都女子大学)日本的一个小规模研究发现健康女性十分钟吃完一顿饭比花二十分钟吃完饭的血糖峰值更高。Consistently high blood sugar can lead to things like cardiovascular problems in people with and without diabetes.长期高血糖可能导致人出现心血管问题,不论是否患有糖尿病。Now, if all this makes you want to eat more slowly, nutritionists have some tips, like using smaller spoons, consciously chewing more, and taking a sip of water in between mouthfuls.如果以上的信息让你想吃得更慢一点,营养学家们提出了一些建议,比如使用更小的勺子、注意细嚼慢咽或者在大口吃东西的间歇喝口水。Of course, if you're worried your eating speed might be related to an eating disorder, it would be a good idea to seek medical advice.当然,如果你担心你吃东西的速度和某种饮食障碍有关,最好就此寻求医生的建议。

Energy 能量Studies show the caffeine in both can improve your attention span, alertness and reaction time.研究表明,茶和咖啡中所含的咖啡因都能提高你的注意力、清醒度和反应速度。A standard cup of brewed coffee has around double the amount of caffeine than is in black tea.一杯标准杯现煮咖啡中咖啡因含量约为一杯红茶中咖啡因含量的两倍。But too much caffeine can lead to jitteriness, overstimulation and sometimes heart palpitations.不过摄入过多的咖啡因会让人紧张发抖、过度刺激,有时还会引起心悸。Tea, unlike coffee, contains L-theanine, a substance that eases the stimulant effects of caffeine. It can also decrease anxiety and improves focus.茶不同于咖啡,茶含有茶氨酸,这种物质能缓解咖啡因的刺激作用。它还可以减少焦虑,提升注意力。2. The gut 肠道Both tea and coffee are rich in substances called polyphenols. They help digestion by boosting the microorganisms in our gut.茶和咖啡都富含一种叫作茶多酚的物质。茶多酚可以助消化,促进肠道中微生物的生长。Coffee has almost twice as many as green tea, which in turn has more than black tea.咖啡中的茶多酚含量几乎是绿茶的两倍,而绿茶中的茶多酚含量又高于红茶。3. Disease prevention 疾病预防Different studies have found tea and coffee can lower the risk of heart disease, type 2 diabetes, stroke, and there are links to a reduced risk of some types of cancer.不同的研究发现,茶和咖啡都能降低患心脏病、2 型糖尿病和中风的风险,而且这两种饮品的摄入都与一些癌症的患病风险降低存在关联。So, it's a draw!综上所述,茶和咖啡打了个平手!

They also require more resources for manufacturing, since they are usually heavier and bigger.绝大多数 SUV 都以污染环境的燃料为动力源。SUV 也需要更多的资源来生产,因为它们通常比其它车更重更大。That was why smaller, energy efficient and electric vehicles started making inroads – but they couldn't displace SUVs.这也是为什么更小型的节能车和电动车开始在市场上攻城略地。但它们依然无法取代 SUV 的地位。In fact, SUVs slowed their growth in several markets instead.实际上,SUV 在一些市场中反而遏制了电动车销量的增速。(Source: IEA 国际能源署)And SUVs have led to oil consumption increasing by half a million barrels a day. There were more than 360 million SUVs worldwide in 2023, resulting in 100 million tonnes of carbon emissions increase from the previous year.(来源:IEA 国际能源署)SUV 还使得全球每日的石油使用量增加了五十万桶。2023 年,全世界有超过 3.6 亿辆 SUV,这让当年的碳排放量比上一年增加了一亿吨。(Source: IEA 国际能源署;UK parliamentary climate change committee)SUVs have also offset the transport sector's decarbonisation achieved by small, energy-efficient and electric vehicles.(来源:IEA 国际能源署;UK parliamentary climate change committee)SUV 还抵消了交通行业通过发展小型的节能车和电动车所带来的碳减排成果。Road transport answers for 12% of global carbon emissions.道路交通占全球碳排放量的 12%。(Source: IEA 国际能源署)Only around five percent of SUVs on the road today are electric.(来源:IEA 国际能源署)目前道路上只有大约 5% 的 SUV 是电动的。But industry representatives say an increasing number of new ones are electric.但行业代表表示,越来越多的新 SUV 都将是电动车。Electric SUVs still require bigger batteries due to their size.由于体积较大,电动 SUV 依然需要比其它车更大的电池。Environmental campaigners say that further increases demand for critical minerals, putting pressure on the planet.环保人士称,这会进一步刺激对关键矿产的需求,增加对地球资源的压力。Forecasts, however, show continued growth of SUVs.不过,预测显示 SUV 的数量还将继续增长。

That's because the water expands as it freezes, bursting the cell walls that give the plant its rigid texture.水分含量高的蔬菜和水果在解冻后会变得软塌塌、稀糊糊。这是因为水在结冰时会膨胀,从而导致赋予植物硬性结构的细胞壁发生破裂。Mayonnaise and cream can separate and curdle.蛋黄酱和奶油会分层并结块。They are emulsions that delicately bind together oil and water, which all fall apart after defrosting.它们都是将油和水微妙结合的乳化物,而油和水在解冻后会发生分离。You can freeze cooked rice, but you'll need to cool it down quickly first.你可以冷冻煮熟的米饭,但在冷冻之前需要让米饭快速地冷却下来。(Source: UK Food Standards Agency 信息来源:英国食物标准局)Bacterial spores on the rice could start multiplying and may cause food poisoning otherwise.如果不这样冷却的话,米饭上的细菌孢子可能会开始繁殖并可能导致食物中毒。Whatever you freeze, it's important to wrap it well.

There's a bear there, it's crossing the road. We heard crackers going off, and now the polar bear alert team are moving around, so we're gonna get back in the car. So you can just see it through the trees there."维多利亚·吉尔 BBC 通讯员“并且……哦,我们是不是应该离开这?那里有一头熊,它正在穿越公路。我们听到驱熊的空包弹的声音了,而且现在北极熊预警小组也开始行动了,所以我们要回到车里。你刚好能在那边的树丛后面看到它。”A BBC team cut filming short after spotting a polar bear nearby in the Canadian town of Churchill, located on Hudson Bay.一支 BBC 拍摄团队因在拍摄过程中发现了一只北极熊而中止了拍摄,团队的拍摄地点位于加拿大小镇丘吉尔,临近哈德逊湾。Known as 'the polar bear capital of the world', conservation scientists come here to monitor one of the most southerly polar bear populations in the world.丘吉尔以 “北极熊之都” 的称号闻名世界,环保科学家们来到这里监测世界上最南端的北极熊种群之一。The bears gather here, waiting for the bay to freeze and hunt seals, but warming temperatures delay this longer each year.北极熊会在这里聚集,等待海湾结冰从而捕猎海豹,但逐年升高的气温让这场等待变得越来越久。Alysa McCall, Polar Bears International"We had about 1,200 polar bears here in the 1980s, and now we have closer to about 618. So we've lost almost about 50% of these polar bears in the last several decades."阿莉莎·麦考尔 北极熊国际协会“1980 年代间这里有大约 1200 头北极熊,但现在北极熊的数量大约为 618 头。所以说这里的北极熊数量在过去的几十年间减少几乎约 50%。”The longer the bears stay on shore, the hungrier they get, and they may turn to alternative food sources, including humans.北极熊在岸上停留的时间越久就会越饥饿,然后它们可能就会转向其它食物来源,包括人类。Victoria Gill, BBC correspondent"Everyone here that we've spoken to is very aware of it all the time. And... oh, should we go? I can hear cracker shots over there. There's a bear there, it's crossing the road. Get in the car!"维多利亚·吉尔 BBC 通讯员“我们在这里见到的每一个人都会时刻保持对北极熊的警惕。并且……哦,我们是不是应该离开这?我能听到那边有驱熊的空包弹声。那里有一头熊,它正在穿越公路。快上车!”
