大家好刻苦啊,学习...:handshake

不错，我以后也跟着ＬＺ练

bfyakumoUID: 2326969

一起来练。。。:)

没关系，小楣你尽管改吧，这样反而更利于察看，多谢了:)

谢谢woodman，这句确实是：
fuzzy(毛绒绒的，不是fussy爱挑剔的) fliers for pollination(应该是这个，授粉，不是Polynesian波西尼亚人).

才知道为什么自己听抄过后，却不能理解这句话的意思呢，原来把pollination 听成Polynesian，太可笑了:loveliness: ，哈哈。还多谢woodman及时指出:handshake

不过dubbed那句怎么解释呢？ :confused:

Most of the universe’s stuff was apparently dark matter invisible material pervading the universe and supply the bulk of gravitational attraction holding galaxy clusters together.

The Hubble space telescope has found was looks like a ghostly ring. The remnant of a massive collision between two galaxy clusters sometimes last to 2 billion years. The ring is about 2.6 million light-years across, lies of about 5 billion light-years from earth. A John Hopkins research team notices the ring. They can’t directly see it of course. But they infer its existence because its gravity bends the light more distant galaxy in the background. One researcher was initially annoyed with the ring because it sued some kind of problem or error. A literature search though turn out the evidence of collision between galactic clusters near the ring. And computer simulations show that the dark matter ring wouldn’t the result like the ripple on the pond.

Scientific American 60 Second Science 更新时间？
Science Talk 更新时间？

最近觉得mp3 文件的声音比以前小了，是文件还是我的电脑的问题？

dubbed那句我也不理解意思，当时是根据发音找的单词，后来google了一下，果然是这个词，只是意思至今不解，呵呵，请小楣赐教。
有没有觉得生物的段子最难啊？好多单词不知道，所以即使听到了也不知道哪个词，只能根据发音查字典。最近在听TTC，头晕啊~~

woodmanUID: 161906

更新时间具体不清楚，好像每天下午就更新了，至于大小，有的时候网络不好的话，不能完全下载，我经常也是下载了一听，只有几秒钟的录音，晕，呵呵，等网络好点重新下载就基本没问题了。所以，不是你电脑的问题，不必多虑。你手脚很快啊，我经常一忙就忘记下了，呵呵，然后到gter一看，已经有人听抄了，羞愧，呵呵。
顺便赞一下，你听力真好啊，学习ing~

刚才发现这个帖子点击率有7000多次了，哈哈，作为发起人，好开心哦。感激小楣的鼎力支持，还有xixihehe0167，forerunner，每天的讨论让我受益很多。继续努力。

Enzyme Points Way to Pacemaker Drug
A heart beats 3 billions times in an average life span and sometimes those beats raise, like running into a grizzly bear, or climbing stairs, or falling in love, such moments can more than double the average heart rate of170 beats per minute, speed it up to 260 beats. And we feel it, pulpation(n.成髓,髓化), diseases, breathless. Scientists have a good idea what causes raising heart and increasing the general incentive signal cells located at the operate chamber. The cell then sets off dominos that affects the speeds of muscle contractions which the scientists don’t understand though is what makes the heart beats slow back down. But the team in the University of Illinois Chicago city finds a promising clue if isolated enzyme caught p21 activated kineids or pack 1 that affects channels inside of pacemakers shell. The scientist showed that by turning on pack 1, they can reduce the channel activity and slow down the heart. They are now working on finding a drug treatment that control science enyzme. Hope this medicine might take place the artificial pacemakers. Be still my beating heart.

Searching For What's Behind the Bee Decline

You’ve probably heard the world honey bees have suffered from stinging losses lately that’s a big story for us too. Up to 12 billion dollars in crops rely on the fuzzy flyers for pollination, of the 2.4 million bee colonies in US about 1 million died off this past winter, big declines are also be seen in Europe and Asia. The die-off has been doubled by the colony collapse disorder and vanishing bee syndromes. A couple of species of mites that attach bees were responsible for similar die-offs in the winter of 95, 96, and 2000, 2001 and the mites maybe partly be to blame because recent bee loss but a quarter of current seems carnages unrelated to mites and other pests, other suggested causes of being declining include genetically modified foods, parasites, pesticides, cell phone radiation. But a bee scientist expert Necolas Corom(人名) in Cornell University said last week that definitive cause remains illusive. He would spend this summer investigating honeybee colonies throughout southeast trying to solve the cases of dead bees, and here is open the buzzes with the answer.

请问WOODMAN, 听TTC,弱问,TTC是什么呀:funk:
