Scientific American 60 Second Science听抄（有音频文件）

wcr27UID: 174576

若若的问一下 xixihehe0167 所听抄的 May 3 episode 中 fraud busting program 是不是有点像一种
反欺诈的程序阿？ 还有 what the hack 在这里代表什么意思啊？
我不是听得很懂 是不是科学家出钱让人们 测试他们研发的的反欺诈程序 要是谁做出的rating 瞒过了反欺诈程序 就可以把东西 拿走了 ？

xixihehe0167UID: 2253387

to wcr27:

我个人觉得 fraud busting program 就像是你说的一种反欺诈的程序，bust作vt有一个意思是毁坏，你可以将fraud busting 输入到google里搜索，可以看到相关的词条。
对于类似不懂得短语都可以用这个方法:loveliness:

what the hack我就不是很确定了，google搜到的是[size=-1]What The Hack was an outdoor hacker conference held in Liempde； 不过我觉得用在这里似乎不是这个意思，可能是什么感叹词，或是其他，这个还要请教woodman和小楣

我觉得你总结的大意“是科学家出钱让人们 测试他们研发的的反欺诈程序 要是谁做出的rating 瞒过了反欺诈程序 就可以把prize拿走了” 是对的

wrc27，你学习英语很认真，值得我学习:handshake

今天的作业：），对照大家的修订过了。还是错很多，竟然把关键词rating全部听成了reading，晕～明天继续听！
If you like on-line shopping and you love good scam, then we found a contest for you. scientists of  university  are offering a thousand dollars to a person or persons who can most wildly manipulate a set of on-line readings(ratings). many webs(websites) encourage consumers to read(rate the items they’ve)  purchased. shoppers then use this information to help (them) decide what to buy. unfortunately, such systems are easy pray(prey) for shows looking to make certain products seem more attractive. for example, an unscrupulous author could get all of his family and friends to give his books five stars.  researchers (have whipped up an algorithm)   for identifying such fragile(fraudulent )readings(ratings). Another(and now they are) putting their program to the test which( is where) the contest concerns. to participate, go to www.eatanlab.com slash reading(rating) and download the daily set(data set). then start manipulating, the individual who introduce the largest bias will take home the prize and will show the scientists how they can make the frustrating(fraud busting) program even better. it is fun for the whole family. i give four thumbs up(ah what the hack,eight thumbs up.)

想问问，真实的考试听力也是这样的难度吗？
感觉听这个还蛮难的

lintelleUID: 2297267

真是考试比这个清晰，速度比这个慢。但是考试时的听力段子很长，而且你紧张状态下不知道听力会打几成折扣。所以有时间还是对自己挑战挑战。

to yaya322:  May 4 的听力确实很难，很多地方我也听不出来:confused: 后来找了一个听力比我好的朋友一起帮忙来听，才听出个大概:)

等待小楣和woodman的修改和补充，红色标记的地方都是没有把握或者没有听出来的地方

Episode 169, May 4,2007

We've all heard the old sole(没有听出来，按谐音写的 ) about women who let themselves go after getting married, while female ticks take this post honey moon weight gain to extremes. After mating, female ticks in the family exotic(not sure) increase their mass at astonishing 100 times. Blooming from the size of a sand grain to that of a kidney bean, this post-copulatory growth bird(or blur,or…) is actually an important part of the tick’s whole blood-sucking life style. Females ticks need to fully engorged before they can lay eggs, but virgins are better off staying small so they'll have more time to find a mate. Not that the male ticks have anything against full-bodied females, it's just that ticks meet their matches while they're hanging around on their host and if females become too on what unwieldy, they are morelikely to get knocked off during a good grooming.

As to what spurs the female to really bog up, R. C. of the University of Albert finds that male ticks’ semen contains proteins that trigger engorgement, vaccine against this protein could keep ticks from reproducing and transmitting infections such as Lyme disease. That would be good news forpeople, but bad new for female ticks who dream of being engorgeous.

但是最好说what`s the heck 这个比what`s the hell 好一点。
就像说dumb 比说 stupid 要好一点。

We’ve all heard the old saw(谚语) about women who let themselves go after getting married. Well female ticks take this post honeymoon weight again to extremes. After mating, female ticks in the family ixodae (好像有个z的尾音，但照道理这个词在这里不用复数，不解，看到有板油写的ixodids，但是用google查了，只有family ixodae，却没有family ixodids之说。) increase the mass an astonishing 100 times, blooming from the size of a sand grain to that of a kidney bean. This post copulatory growth bur's（实在听不出来了，反正有个很浑厚的元音，后面有个z的发音） actually an important part of tick’s whole blood-sucking life style. Female ticks need to fully engorge before they can lay eggs. But virgins are better off staying small, so they have more time to find a mate. Not the male ticks have anything against full-body females, it’s just ticks meet the matches while they’re hanging around on the host, and find（不确定）what females become too unwieldy, the more likely to get knocked off during a good grooming. As to what spurs the female to really bulk（谢谢forerunner的指正，确实是这个，赞） up. Reuben Kaufman of the University of Alberta finds that male ticks’ semen can take proteins to trigger engorgement. Vaccines against this protein could keep ticks from reproducing and transmitting infection such as Lyme disease. That would be good news for people, but bad news for female ticks who dream of being engorges.
小楣帮助一下，嘻嘻
xixihaha0167，这次听得不错，狂赞一下，呵呵。the old saw是谚语的意思。

楼上是如何听写的？具体步骤是？
边听 边用电脑打？
一般要听几遍？
个人觉得听写很难，其中的专业词汇不知道！:(

May 4, 2007的一点修改

Lyme disease (Borreliosis) is a bacterial infection with a spirochete from the species complex Borrelia burgdorferi sensu lato, which is most often acquired from the bite of an infected ixodid tick.

Female Ticks Have Market On Gluttony
Science Daily — Sex makes you fat. If you're a female tick, that is.

Unfed and engorged tick. (Credit: Professor Frans Jongejan, University of Utrecht, Netherlands, and University of Pretoria, Republic of South Africa.)
The "truly gluttonous" female ixodid tick increases her weight an astounding 100 times her original size after she mates, so a University of Alberta researcher investigated what it is about copulation that triggers such a massive weight gain.
In a new research paper published in the Journal of Insect Physiology, Dr. Reuben Kaufman, from the Department of Biological Sciences, suggests several differences between the ixodid tick and her blood-sucking counterparts that help explain the weight gain. Using mosquitoes, tsetse flies, bed bugs and kissing bugs as comparison, Kaufman found that no one compared to this female African tick when it came to weight gain following mating.
Kaufman suggests that the ixodid tick displays a significant difference in lifestyle from the other insects and that it is adaptive for the virgin to remain small before mating.
First, this species of tick remain on the host for a number of days, rather than minutes. "In this family of ticks, mating takes place on the host," says Kaufman. "Most other insects mate before or after their brief blood meal --the two acts are totally separate, but not with these ticks."
Female ticks require six to 10 days to engorge fully. First, she attaches herself to the skin. Then she feeds to 10 times her unfed weight and finally, after copulation she increases her weight a further tenfold.
On the other hand, the virgin tick rarely exceeds the critical weight necessary for laying eggs. It will hang on to the host for weeks, waiting for a male to find her, says Kaufman. If the virgin gains too much weight and is groomed off the host, it won't reattach itself to another host and continue feeding. "However, if she remains small she still has a chance to reattach itself to another host--hopefully infested with some feeding males-- continuing feeding and potentially mate," says Kaufman. "If a male eventually copulates with her, she will engorge normally and then be able to lay eggs. This is one reason why it might be adaptive for the virgin to remain small until mated."
In terms of what causes the female to become so engorged, Kaufman says that when a tick does copulate, the male's seminal fluid contains two engorgement factor proteins that together act as a signal to tell her to complete engorgement.
Kaufman's future research will look toward the potential to produce an anti-tick vaccine. Some experiments have already suggested that normal, mated ticks are unable to fully engorge when feeding on a host that has been immunized against the engorgement factor proteins. If these observations can be confirmed and extended, an effective anti-tick vaccine to protect livestock and pets could be on the horizon.

可以贴图片吗？如何贴？

We’ve (这个时态当时没听出来) all heard of the old sore (按读音随便拼的,错了,应该是woodman听的saw吧) about women who let themselves go after getting married, while female ticks takes this post-honeymoon weight gain to extremes. After mating, female ticks and the family ixodids（听音拼出来后查了下词典的） increase their mass astonishing 100 times, blooming from the size of sand grade to that of a kidney bean. This post-copulatory growth birth (不确定) actually is an important part of the tick whole blood-sucking life style. Female ticks need to fully engorge before they can lay eggs, but virgins are better of staying small so they'll have more time to find a mate. Not the male takes anything against full body about the females, it just ticks to meet their matches hanging around their host and find what females become too unreally (不确定) . They're more likely to get a lot of stuff during a good grooming. As what's females to really blow up (不确定), Rouben Kaufman of the university of Alberta finds that male tikes’ semen contains proteins, the trigering engorgement. Medicines (仔细听应该是vaccines) agaist this protein could keep ticks we producing (应该是reproducing) and transmitting infection such as Lyme（学到了一个新词，哈哈） disease. That would be good news for people, but bad news for female ticks to dream of the engorges (being engorges是不是语法上有点问题).

这个是我先听，然后再参照了一下WOODMAN的，大家再看看，挑挑听错的地方！

谢谢你的指正哦，呵呵，确实是bulk up，狂赞！听了好久都没听出来。至于听抄的方法，每个人依据具体情况不同，呵呵，基础比较好的话，几遍下来就差不多啦，差一点的话，就多几遍，几个句子几个句子去听啦。必须指出的是，要听完整的句子，不能一个句子断几次哦。也许最开始你觉得很吃力，那就一句一句好了，等慢慢适应了，就几个句子一次去听。要是上了新的台阶就可以整段整段去听了。我觉得不必要纠缠于个别的专业单词，只要把握他的发音就行了。我也有很多单词不认识，根据发音去找的字典，这也是个很好的方法，呵呵，加深对某些音标的印象。当然，每一次做完听抄顺便记下那些生词也是个收获，扩大词汇量嘛。
贵在坚持啦，呵呵，我的听力也不怎么样，幸亏每次都有xixihaha0167 和小楣帮助。
至于怎么使字体有颜色的问题，点击回复主题，里边不是有选项可以改字体颜色吗？
