英语畅谈时事热点50主题 (50 Topics On World Current Issues)
1. Genetics 遗传学 A:Have you any idea where this science of Genetics is going? A:对于遗传学将怎样发展,你有什么看法吗? 2. The Internet互联网 A: The Internet can be a real pain at times. B: Apart from the spam, and the viruses, the Internet has got to be the greatest thing that ever happened in communications. A: The spam, and the viruses, are fairly easy to fix; the real problem with the net is the amount of info that gets posted. B: But, that’s the beauty of it, you can find out about anything you want to know. A: Yes; but, how do you know the information is correct? B: That’s easy; just check the references. If you log onto a good web page the information should be reliable. A:Ah! You see. You said “should be reliable.” That’s the whole problem. How do we know what is a “good” web page and how do we know if the information is “reliable”? B:Well! I suppose, you just have to go through all the pages that come up, when you do a search. A:I bet I can find you a dozen pages that say, sugar is one of the best energy foods you can have and, another dozen pages to say, it will kill you. B:That’s where you have to use your judgement. A:But, that’s what I go to the Internet for; to find out the information so that we can make a judgement. B:The Internet isn’t just for getting that sort of information. E-commerce has become a boom industry because you can buy, or sell, anything on the Internet. A:Yeah! And you can get ripped off too. I know people who have used their credit card on the Internet and had to cancel the card to stop it being used illegally. B:That has to be a rare case. There are, real, secure ways to make payments through the Internet where that can’t happen. A:Don’t you believe it! Credit card fraud over the Internet is a huge international problem. Look it up. There are web pages dedicated to providing the facts. B:Who put those pages on the Internet? Is it the credit card people? A:No way. They would never publicise that sort of information. You have to look up the alternative sites, and the blogs. B:I don’t know. I never trust those alternative sites and, the blogs can say anything, true or false. A:Talk about coming around in a full circle! Isn’t that just what we were talking about before? How do we know what is right and what isn’t? B:Aw! Now, you’re just trying to confuse me! A:有时候因特网真令人头疼。 B:不会吧,网上除了有些垃圾邮件和病毒之外,因特网可以说是迄今为止人类通讯领域发生的最伟大的一次革命。 A:垃圾邮件和病毒都好解决,真正的问题是网上每天发布的海量信息。 B:这不正是网络的优点嘛,你可以在上面找到任何你想要了解的东西。 A:没错,可是你如何才能知道这些消息是正确的呢? B:这很简单,只要检查一下参考资料就可以了。要是你访问了一个好的网站,那么上面的信息就应该是可靠的。 A:哈!你看!你也说了,“应该是可靠的”。这就是问题的关键。我们怎么知道哪些网站是“好”的,哪些消息又是“可靠”的呢? B:在搜索的时候,我想你恐怕需要浏览查看所有跳出的网页。 A:我敢打赌,我可以找到几十个网页说糖是你所能吃到的、最好的补充能量的食品,同时也能找到几十个网页说糖会对你的健康有害,吃多了会要你的命。 B:如果真是这样,那此时就需要你自己作出判断了。 A:可我们上网的目的就是为了查找各种信息,以便于我们作出判断啊。 B:不过,你要知道,因特网不仅仅是给人们提供信息的,它还是一个网络交易平台,你可以通过网络买卖商品,这样,因为有了因特网,现在电子商务已经成为了一个迅速发展的行业。 A:你说的没错,但也别忘了,你或许也会因此被骗。我就听说过一些人由于在网上购物时使用了信用卡,后来信用卡就被人盗用了,害得他们不得不销卡。 B:那简直太罕见了。要是通过真正的、安全的方式进行网上支付,就可以避免这样的情况。 A:你难道不相信吗?网上的信用卡欺诈已经成为了一个影响广泛的国际性问题。你看,这里有关于这个事件的专门网页。 B:是谁把这些网页放到网上的?是那些信用卡工作人员? A:当然不是了,他们永远不会公布这类信息的。你需要去查看那些相关网页和博客。 B:我不清楚。我从不相信那些相关网页,还有那些博客。我感觉那上面不论真假,随便说。 A:你看,说来说去,我们又说回来了——我们怎么才能知道哪些信息是正确的,哪些不是呢?——这不正是我们之前所讨论的吗? B:哦!你简直把我搞糊涂了!
A:The best part about motor sports is when they prang. B:You’re a bit of a sadist if that’s where you get your thrills. A:Why do you think the TV programs always show the smashes over and over again? It’s because that’s what the audience wants. B:So, I suppose, you are a fan of stock car racing? A:Not really. There’s plenty of crashes in that but, I don’t much like those sorts of races where they go round, and round, on small, oval, race tracks. B:Then you don’t go for the Indianapolis 500? That’s on a big, concrete, oval track. A:No. The Formula One races are better. There’s a lot more skill involved with them and they race on properly designed tracks. B:What about the Indy road race competitions? They are just as good. A:Nowhere near as good. What I have seen of them; the roads are too narrow and the drivers have very few chances for passing. B:That’s, probably, why there always seems to be more prangs with the Indy races than Formula One. A:The trouble with both those competitions is the variations allowed in the cars. A driver in the better car will, invariably, beat the better driver in an inferior car. B:The variations are all part of progress. That’s why they have a manufacturer’s Championship to recognise the better car maker. A:I suppose you’re right. It just seems unfair to me. If you have a more powerful car you have a better chance to win. B:There are some classes where all the cars have to have the same type of engines or, at least, the same size of engine. A:That’s right. Then it really comes down to the skill of the drivers. Those competitions are run on an equal basis. B:Motor bike races are done by engine size. The 500 cc bikes race against each other and the 1000 cc bikes are all in the one class. A:And that’s good. The manufacturers are allowed to make modifications to the mechanics, and streamlining, provided they comply with the safety guidelines. B:Speaking of safety; that’s one of the amazing things about those modern racing cars; the way some of the drivers walk away from some horrendous crashes. A:It surely is. Especially when you think of the speed those vehicles are doing. B:That’s just proof of how well the cars are designed these days. A:看赛车运动最爽的时候就是当看到它们相撞的时候。 B:如果那也让你兴奋的话,那你可有点儿施虐倾向啊。 A:你知道为什么电视节目总是重播汽车相撞的画面吗?那是因为观众就喜欢这个。 B:这么说,我想你是一名赛车爱好者啦? A:那倒不是,我是因为看多了赛车撞击,看它们一圈一圈绕着小型椭圆的赛道比赛的样子,我不是很喜欢这类比赛。 B:那你不看印第安纳波利斯500赛事了?那是在一个大型的混凝土椭圆轨道上的比赛。 A:不喜欢。我更喜欢F1。这项比赛赛道是特别设计的,而且比赛也需要很多技术技巧。 B:那你觉得Indy比赛怎么样?是不是也挺好的? A:一点儿都不好。我以前看的时候觉得,路太窄,选手很难有机会超越。 B:这可能就是为什么它总是比F1比赛有更多的撞击的原因吧。 A:这两个赛事的问题是在赛车的变化改装上。如一个技术好的赛车手,如果用的车较差,那他肯定就赢不了一个使用了好车的选手。 B:赛车的改装是赛车制造技术进步的源动力啊。这就是为什么他们专门有一个汽车厂商锦标赛,来评选谁是最佳汽车制造厂商。 A:我想你这么说有道理。不过,我觉得似乎很不公平。因为如果你有一辆性能更好的车,你当然就有更大的机会赢。 B:所以赛车是有分类的。比如,所有的车必须有同类型的发动机,或者,至少是同尺寸大小的发动机。 A:这就对了,这就真的要依靠选手的技术了,这样的比赛才是公平竞争。 B:摩托车比赛要依靠发动机的大小来划分为不同的等级。比如,500cc规格的摩托车是一个级别,而1000cc的摩托车则在另一个级别。 A:那也不错。可以允许制造商对汽车的结构和流线外观做适当的修改,只要符合安全生产的要求。 B:说到安全,现代赛车的质量真是让人惊叹,看看那些赛车在撞得面目全非了之后,赛车手依然能好好地走出来! A:的确,特别是当你想想那些赛车极高的行驶速度。 B:这也正好证明了当今赛车的设计质量真是让人佩服。 |
