About one year ago 大约一年前 we released the how to stop acne video. 我们发布了预防痤疮的视频 Now still to this day 直到现在 I honestly can’t believe how well it’s done 说实话 我都不敢相信它这么受欢迎 The amount love it’s had, the amount of views it’s had, nearly 1 million！ 点赞数和播放量接近百万! Thank you! 非常感谢你们！ Now by far one of the most common comments on that video 目前为止 大家问的最多的问题 was about pores 都跟毛孔有关 and more specifically how to shrink them? 比如更具体的 如何收缩毛孔？ So we decided 所以 我们决定 let’s do a full video on this topic. 以此为题做一期视频 Let’s begin. 开始吧 OK so why do we get enlarged pores? 首先 毛孔为什么会变粗大呢？ Well, we all have pores. 我们都有毛孔 But enlarged pores are depressions in the facial skin that carry things like oil 但毛孔粗大是因为皮肤的毛孔中含有油脂类物质 that carry sweat from their respective glands. 这些油脂从各自的腺体排除 So it’s completely normal. 因此它是很正常的 And enlarged pores can be seen in 且毛孔粗大会发生在 all ages and all ethnicities. 各个年龄段和人种中 However certain ethnicities do tend to have larger pores. 然而 有些人的毛孔确实更容易粗大 For instance those of African and those of Indian ancestry 比如那些有着 非洲和印度血统的人 Background done. 介绍完背景知识 Now let’s see how we can shrink these pores. 现在来说说如何收缩毛孔 So Tip NO. 1 as we age 第一 随着年龄的增长 our skin becomes less elastic 我们的皮肤会变得缺乏弹性 and that’s a normal process of ageing. 这种衰老过程 是很正常的 and there’s not actually much we can do about that 我们确实对此无能为力 but sun damage can also cause ageing of the 但晒伤也会导致皮肤老化 skin and it can lead to enlarged pores 从而导致毛孔粗大 Now if you live in the UK or you live in 如果你住在英国或 a country with a similar climate 其它类似温带海洋性气候的国家 you probably only see the sun once or twice a year 你可能一年只能见到一两次太阳 the rest of the year is always cloudy 其他时候都是阴天 And I said that with such a serious face 我说得很夸张 but in reality we do see the sun but it is cloudy a lot at a time 但实际上 我们还是能看到太阳的 只不过多数还是阴天 and you might think to yourself well it’s always cloudy 你可能会想 它总是阴天 I don’t even see the sun I’m not gonna get some damage 我甚至没见过太阳 那我就不会晒伤 But that’s where you’re wrong 其实不然 Because these UV rays can still penetrate. 因为紫外线仍然具有穿透力 And it can still damage the skin 从而损害皮肤 so if you haven’t figured it out yet 如果你还没有好的解决办法 来试试我说的吧 Tip 1 is all about using a good sunscreen every single day 第一 每天都要涂质量好的防晒霜 that protects you against both UVA and UVB radiation 使皮肤免受紫外线伤害 Now if you’re thinking to yourself but Abraham, 如果你在想 亚伯拉罕 which sunscreen do I buy just tell me. 你直接告诉我该买什么防晒霜吧 Well, the good news is I made a video on this not long ago. 告诉你们个好消息 不久前我就此做了个视频 I’ll leave a link up here and in the description below 我会把视频链接放在屏幕上和简介区 on how to buy the best sunscreen from any pharmacy. 视频介绍了如何在药店买到最好的防晒霜 what ingredients to look out for 需要注意哪些成分 and everything you need to know 以及买防晒霜该知道的所有事情 so if you feel like you need more information on this topic 如果你想了解更多关于防晒霜的知识 feel free to watch it at the end of this video 请在视频结尾查看 which leads me on to tip NO. 2 接下来第二点 have you ever heard of sebum 你听说过油脂吗 well if you haven’t you’re not missing out on much so don’t worry 如果没听过 也没关系 不必担心 but it’s basically the oil that we secrete 因为油脂基本上是从我们的 from our face and scalp from our sebaceous glands 脸部 头皮和我们的皮脂腺分泌的油脂 Now here’s the thing increased sebum can lead to enlarged pores 而油脂的增加会导致毛孔粗大 Now sebum production depends on many things like 许多因素会导致油脂的产生 age it depends on gender and even weight 比如年龄 性别甚至体重等 Now a lot of these you can’t really do anything about 还有许多你不能改变的东西 but there have been reports that if you are overweight 但是有研究表明 如果你体重超标的话 if you lose weight it can help reduce sebum production 减肥 将会帮助减少油脂的产生 and help to reduce the appearance of enlarged pores 帮助缓解毛孔粗大问题 Tip NO.3 non-comedogenic skincare products 第三 没有诱发粉刺成分的产品 which is basically a fancy word 基本上是一个好的产品 for products that aren’t going to clog your pores 因为它不会堵塞你的毛孔 because when you pores clog 当你的毛孔堵塞时 they expand and it can make them appear much larger 它们将会膨胀使自己变得更大 so to avoid clogged pores 为了避免被堵塞 look for any of the following terms on skincare products that you use on your face 从你用的面部护肤品中 寻找以上这三条术语 and if you don’t see them then avoid using it 如果你没有看见以上三条 千万别用！！！ which moves me on to Tip NO.4 acne 接下来 第四点 痤疮 I’m afraid it is associated with enlarged pore 我担心它与毛孔粗大有关 so what we need to do 所以我们该如何预防它呢？ is keep it under control with the correct care and treatment to avoid it 我们要通过正确的护理和治疗来防止它 from becoming inflammatory and enlarging those pores 变成炎症 从而扩大毛孔 Now if you haven’t seen my how to treat acne video 如果你还没有看过我关于如何应对痤疮的视频 I will leave a link up here and in the description below for you 我会在屏幕上和简介区留下链接 so feel free to watch it 请注意查看 but please remember that if the tips aren’t helping 但请记住 如果这些方法对你没有帮助 your acne is getting worse 你的痤疮更严重了 and you are in distress, 使你感到烦恼 then please always speak to your doctor 请及时就医 Tip NO.5 don’t leave it 第五 不要放任毛孔变大不管 remember as we age 记住随着我们年龄的增长 generally speaking pores are going to get bigger 毛孔都会变大 so if you see no improvements 所以如果你的毛孔没有缩小 and it’s not getting any better 也没有任何改善的迹象 then always beat you doctor first 抓紧联系你的医生 make them aware of this 告知他们你的情况 they may prescribe you some treatments 让他给你开些药方 be

如何搭建以太矿机 以太币是一种类似比特币的加密电子货币 2017年因其价值快速增长而大受欢迎 你可以通过线上购买 或者搭建自己的以太矿机挖矿来获取以太币 Today we’re gonna be building an ethereum mining rig. 今天我们将来搭建一台以太矿机 These mining rigs run mathematical equations millions of times per second 这种矿机每秒可进行数百万次运算 in order to exstract ether from the ethereum network. 来挖掘出以太网中的以太币 While you probably won’t get filthy rich of building an ethereum mining rig, 虽然建个以太矿机不一定让你富得流油 you can make a decent amount of money, 但如果你电脑连了数量可观的GPU（图形处理器） depending on how many GPUs you hook up to the computer. 就能赚一笔不错的收入 The total cost of building an ethereum mining rig 搭建以太矿机的总成本 can range anywhere around $800 to well over $3,000 在800美元到3000美元以上不等 depending on the quality of the components you use to build the computer. 取决于你搭建计算机所使用的配件的质量 In order to build an etherium mining rig, 搭建一台以太矿机 you’ll need a bunch of aluminum angles, 你需要一捆角铝 some cheap wooden blocks, 一些便宜的木板 a power supply unit, 一个电源装置 a motherboard, 一个主机板 power cables to connect all of them, 连接组件的电缆 random access memory(RAM), 随机存取存储器（RAM） central processing unit(CPU). 中央处理器(CPU) Here we have a heatsink span, 这里还需要一个散热器 which is used to help dispel heat from the CPU while it’s running. 帮助运作的CPU散热 These are powered risers. 这些是显卡转接线 These are going to be used to connect your GPU units to the motherboard 用来连接你的GPU到主机板上 while also keeping them elevated above the motherboard to help dissipate heat. 同时使GPU距主机板有一定高度 以便散热 These are the graphics processes units which would really make the Ethereum mining rig tick. 这些图形处理器是让这台以太矿机运作的关键 The same sorts of cards that are used to play video games. 它和电子游戏中使用的GPU是同一类 But in this case they’re going to be used to run the same operations 但在这里 这些GPU将反反复复执行同样的运算 over and over millions of times per second. 每秒执行数百万次 To actually go about building your mining rig, 开始真正着手建一台以太矿机 all you’re going to need is a pretty basic power drill, 你所需要的就是：一款非常基础的电钻 a small screwdriver 一把小螺丝刀 and maybe three dozen self-driving screws. 和大约36个自攻螺钉 Alright so first thing we’re going to do is we’re gonna build the computer’s case 好了 首先我们要搭建一个计算机机箱 just going to consists of aluminum angles cut to size. 我们需要用到切成一定大小的角铝 We have five that are cut to 24 inches, 其中五条切成24英寸 and eight that are cut to 14 inches. 八条切成14英寸 用螺钉将14英寸的角铝固定成两个正方形 用24英寸的角铝连接两个正方形底面 最后一个24英寸角铝用作隔条 来放置GPU Alright so once you have your frame the next thing you’re going to do 好了 固定好框架 接下来 is add the wooden blocks where it’ll be mounting the motherboard. 要放上用来固定主机板的木板 用螺钉固定好木板条 Alright, now your frames are ready to go, 好了 这样框架就准备好了 It’s time to actually build the computer. 现在就可以开始搭建计算机了 So the first thing you’ll need to do is 首先 mount your motherboard to the wooden blocks you just screwed in. 将主机板固定在你刚刚安好的木板上面 For this, you’re going to want to use a screwdriver rather than a drill, 这一步最好用螺丝刀，而不是电钻 so you don’t damage the motherboard. 以避免伤害到主机板 So the next thing you want to do 接下来 once your motherboard has been attached to the woodblocks is 完成了上述操作 you’re going to want to put your CPU into the motherboard. 将你的CPU安置到主机板上 And very careful not to touch either part of the CPU. 一定注意不要触摸CPU或CPU插槽 As once the CPU is placed, you’re going to lock it in place with the cover. CPU放好之后 将扣盖盖好使其固定 The next component that you’re going to add 接下来要安装的部件 is the heatsink for the CPU 是CPU的散热器 which is to be placed directly over it. 将安置在CPU的正上方 You’re just gonna wanna 直接将散热器的接头 plug that into the four-pins next to the heatsink. 插在散热器旁边的四针插槽上 Okay, next component is the stick of RAM. 好 下一个是RAM内存条 So once it’s lined up, 对齐好了之后 you’re just going to pop it into place. 就将其摁进去 Don’t be afraid to use a little bit of pressure there. 不用怕 可以稍微用点力气 Okay so the next element is going to be the power supply unit, 好 下一个组件是电源装置 and also there’s going to be all these holes in the back. 电源背面会有这样一些孔 Some of these are aligned with the holes on the motherboard, 其中一些孔和主机板上的孔是吻合的 so the main power input 因此主供电接口 is the 24-pin slot right here. 在24针插槽这里 And then there’s an 8 pin slot right here to connect the CPU. 然后CPU供电接口接在这里的8针插槽里 将24针接头接到主机板上 线的另一头连接电源装置 接着 用CPU的电源线连接主机板和电源 Alright the next component is going to be the powered risers, 好了 接下来是显卡转接线 which are going to be used to connect to the GPUs to the motherboard. 它将用于连接GPU到主机板上 Because these are powered risers you’re going to need to connect them to a power source. 显卡转接线 即显卡电源转接线 顾名思义 需要把它们连到电源上 So we’re going to take the ends of these cables, 因此我们把这些电线的一端 and we’re going to connect them. 连接起来 Alright now you got these connected, 好了 这一部分就连好了 and directs them over top like this. 像这样把它们放在上面 And you’re going to connect the end of the power cord to the power supply unit. 然后将电源线的一端连到电源装置上 And you’re going to want to take these USB connected chips, 再将这些连有USB电线的芯片 and plug them into the PCIe slots on the motherboard. 插到主机板上的PCIe插槽上 And now you’re ready to connect 现在可以开始 the powered risers to the GPUs 把显卡转接线连到GPU上了 So like the other chips you’ll notice that each GPU has a little indent on each end, 可能你会注意到 像其他芯片一样 GPU的各边上都有一个小凹槽 which matches up with the plastic on these, 它们

Flu can be very unpleasant 流感可能会非常让人不舒服 but if you’re otherwise fit and healthy 但如果你还算身体健康 it usually lasts about a week or two 流感通常只会持续一到两周 but if you are in a risk group 但如果你属于易感人群 it can make you more at risk of potentially serious complications of flu 你患严重流感并发症的风险可能会更高 and nobody wants that 没人想要这个结果 in this week’s video 通过观看这周的视频 I’m going to make you a flu vaccine pro 我将会帮你成为一个流感疫苗的专家 now you may be wondering 现在你可能在想 who is in the at-risk group 流感易感人群都有谁 well it’s quite a big list 其实包括很多人 which includes over 65s pregnant women people 比如65岁以上的人 孕妇 people live in residential homes people with learning disabilities 住养老院的老人 患有学习障碍的人 and certain medical conditions 和一些患有特定疾病的人 like asthma COPD diabetes and many more 如哮喘 慢性阻塞性肺病 糖尿病等等 I will leave a full list in the description below 我将在下面的说明中附上完整的列表 now if you a loved one a family member 如果你自己 你爱的人 你的家人 anyone you know is in the at-risk group 或任何你认识的人属于易感人群 it’s recommended that you have the flu vaccine every single year to protect yourself 建议大家每一年都接种流感疫苗来保护自己 now you may be thinking to yourself with Abraham 现在你可能和Abraham一样在思考 protect me from what what do I need protecting from 保护我什么？我需要预防什么？ well I’m going to tell you because if you are in the at-risk group 让我来告诉你 如果你属于易感人群 and you get flu 你得流感之后 you’re certainly a much higher risk of developing serious complications 患严重并发症的风险无疑更高 one of which for example is pneumonia a lung infection 比如说 肺炎 一种肺部感染 and in the UK on average 在英国平均每年 flu kills about 8,000 people per year 有大约8000人死于流感 now if you’re watching this video 如果你正在看这个视频 and you live in the UK 而且你正住在英国 well the good news is that 那么好消息是 the NHS flu vaccine is available every year 易感人群现在每年可以免费接种 free of charge for anyone who is in the at-risk group 由英国国民健康保险制度所提供的疫苗 and you can get this vaccine at your local pharmacy at your surgery 在当地的药店或诊所即可免费获得此疫苗 all of this is provided free of charge by the NHS 所有这一切都由英国国民健康保险制度免费提供 so you now know the background 所以现在你知道了疫苗接种的背景 you know the complications of flu 知道了流感并发症 and you also know the importance of getting the flu vaccine 也知道了接种流感疫苗的重要性 but what about the flu vaccine itself 但是关于疫苗自身呢？ because I’m sure you’ve got lots of questions about it 我确信你有很多疑问等待解答 and I know just the person to speak to 而我知道该去问谁 I’ve decided to get some help from a good friend of mine 我决定去求助一个好友 which you’ll most likely know from a popular TV show 你很有可能在一个有名的电视节目中见过他 called GPs behind closed doors 《门后的医生们》 his name is Dr. Amir Khan 他就是Amir Khan医生 and I’ve come to his surgery to find out more 我去了他的诊疗室 想了解更多 I’ve come with questions the viewers want answers 我是带着观众们的问题来的 so let’s just dive in 所以我们就开门见山吧 so if question what how effective is the flu vaccine 第一个问题是 这个流感疫苗有多有效？ the flu vaccine works better in some years than in others 流感疫苗在某些年份比其他年份的效果要更好 the problem is the virus keeps changing 因为流感病毒是在不停变化的 so it’s difficult to predict 所以非常难以预测 last year in the UK 去年在英国 the vaccine prevented 60% of cases of flu 该疫苗降低了六成 in adults aged over 65 65岁以上人群患流感的风险 yes so last year there was actually two types of flu vaccines 是的 所以去年实际上有两种流感疫苗 and for those aged over 65 为65岁以上的人 they were offered the trivalent flu vaccine with an adjuvant 提供了带有佐剂的三价流感疫苗 and those under 64 who were in the at-risk group 为64岁以下的易感人群 offered a quadrivalent flu vaccine 提供了四价流感疫苗 and the results are pretty good so far 到目前为止效果还不错 that’s correct adjuvants helped lengthen and strengthen 对 佐剂可以延长和加强 your immune response to a vaccine 你对于疫苗的免疫反应 and they shown to make vaccines more effective in older adults 这使得疫苗对老年人更有效 that’s fantastic 那太棒了 and this helps lead me on to my next question 这也引出了我的下一个问题 which is all about ingredients 是关于疫苗成分的 what’s in these vaccines are they harmful at all 疫苗里都有什么 有有害成分吗 well vaccines contain tiny quantities of substances 疫苗含有各种微量物质 which are found naturally in the body 都是天然存在于人体之中的 for example many vaccines contain salts such as sodium and potassium 例如 很多疫苗都含有盐 比如说钠和钾 which help regulate the acidity of a vaccine 这有助于调节疫苗的酸度 other ingredients help preserve and stabilize the vaccine 其他的成分使得疫苗易于保存 保持稳定 whilst improving your immune response to it 同时也能增强你对于疫苗的免疫反应 so to summarize 所以我们总结一下 are the ingredients harmful for our body no 这些成分有害吗？ 不 are the ingredients normal for our body yes 这些成分对我们身体合适吗？ 是的 which they’ve notes my next question 这又引出了我的下一个问题 how safe is the flu vaccine 流感疫苗有多安全 well just like everything in life 就像我们人生中的各种事情 the flu vaccines do carry some risks 它的确有一些风险 but most of these risks are fairly minor 但大多数风险都相当小 such as swelling or redness at the injection site mild fevers 比如注射部位肿胀或发红 轻度发烧 nothing serious 没有什么严重的 severe reactions to the vaccines are rare 对该疫苗的严重不良反应非常少见 I think in general very few people are unable to get flu vaccine 大体上来说 我认为很少有人无法接种流感疫苗 however it is worth mentioning 但有必要提一下 that if you do have an egg allergy 如果你对鸡蛋过敏 it’s worth letting your healthcare professional know 有必要告知相关的医务人员 just so that they can give you a suitable vaccine 这样他们能够给你提供合适的疫苗 I think it might also be useful 我觉得在说明里给出更多 to put more information in
