Drug Straightens Out Jetlagged Hamsters


Scientists in Argentina have found that hamsters recovered more quickly from jetlag, when they take a drug before the flight by E.D. OK, there may be a lot of things you are wondering right now, like is jetlag a big problem for hamsters? Or where are these hamsters going with their exercise views and their reptiles function prescription. Here's what we know jetlag happens when your body club doesn't agree with the clock on the wall, because you have crossed a couple of time zones, the mismatch can be grogged and disoriented and even disrupts your sleeping cycles until you are able to reset your internal time piece. Would the same thing happen to the hamsters, when scientists booked them on the right eye from witnessed are the Bucharest or laboratory equivalent turning out light 6 hours early. It then takes the jetlag a little future to as well figure out when to start running exercise wheels, which they usually do after dark?  What the Argentinean researchers found that the hamsters given by E.D. the night before the time change, recover faster than the hamsters do it without the drug. Whether similar treatment will provide relief to very world travelers, the experiment is properly being innervated done but not reported.

1：News thatchilly makes all you feel is under out there. Hark(听，倾听) withrelief. 是什么意思啊?

我不能确定，我的理解是：这里的新闻可能使你听了感觉不舒服（发冷，起鸡皮疙瘩之类的意思吧）（因为文中讲了什么家里有很多toxin之类），那么随便听听好了，不必太紧张。呵呵，不能直译，所以只能提供自己的拙见了，不一定正确。

2. mp3中的最后News thatchilly makes all you feel is under out there. Hark(听，倾听) withrelief说完后的声音是什么？
不知道，呵呵，我只能确定是Steve Mirsky的声音。突然想起有一次他在播音里边啃水果的声音，很搞笑，呵呵

It then takes the jetlag like a little(不确定，而且觉得听漏了) for a while tofigure out when to start running in the exercise wheels which they usually doafter dark? What the Argentinaresearchers found is that hamsters given by Viagra a night before the timechange recover faster than hamsters do without the drug. Whether similartreatment would provide relief to weary world travelers, this experiment has probablybeen individually done but not reported.

Actually this is the most famous fiction "The Adventures of Tom Sawyer" by Mark Twain.
you can listen both English and Chinese.
The text is also there.

You may also find "War and Peace", "Pride and Predudice" and other world class works on the wwenglish.com

听抄一个月了 呵呵 发个贴庆祝一下 5.23 Ameican scientific 60s science
Ambulance is rushing you to the emergency room and you're losing consciousness. The medical grasp a face mask and start feeding you a stream of pure oxygen to cause damage to your brain? A new UCLA brain damaging study is a part of  growing body research that suggest inhaling pure oxygen is bad for you. The researchers did MRI brain scan for 14 kids age 8 to 15 .In one test ,with feed of pure oxygen, in the second, 95% oxygen and 5% carbon dioxide. With pure oxygen the kids'  breathing quicken and blood vessels constricted, preventing oxygen from reaching the brain and heart. Then things got worse. The hypothalamus responded to the emergency signals the body  sending by dumping a massive flood of hormones and neurotransmitters into the blood stream. Which interfere with heart’s ability to pump blood and deliver oxygen the worst thing in the crisis (刚听成christ 了^-^)situation. But adding a little sort(short?not sure) of carbon dioxide calm the hypothalamus. The blood vessels relaxed, and the surge of dangerous chemical stopped. Because when it comes to the oxygen you can have too much of a good things.

It's a good site.

Although I know a lot of word in reading and listening,
I feel I can't write freely, it's difficult to compose a sentence even use the simple word.
What should I do to improve my writing?:confused:

I think you must kown the structure of a sentence.

Fingerprint The Little Weasels  

Researchers from the Wildlife Conservation Society and New York State Department of Criminal Justice teamed to develop technology to capture and analyze paw prints from fishers, a species of weasel.

The criminal justices says has long ? fingerprints of weasels the kind of steal cars, rob stores and get ? the river then there is the carnivores of mammal called fisher a species of weasel that’s once again doing pretty well up the Hudson river in northern New York after almost being driven to extinction in the 1930s. And now researchers can track fishers by treating them like criminals they fingerprint them which is quite a trick since fishers don’t have them fingers. But their little paws do have patterns that are unique to each individual. There is the only carnivores know have such desirable prints. Where human fingerprint ? system ? fisher prints are patterns of dots and the dots (?damy) the computer software use to compare human fingerprints. So scientists from the Wildlife Conservation Society teamed with experts from the New York state department criminal justice to develop a new technique analyzing compare fishers prints leading to more accurate population estimates. The fisher is wondering into foot bait boxes leave prints and (pop ?) without again. Which some might say ?makes virtually identical to criminal justice system.

please correct......:handshake

A criminal justice system long kept fingerprint as well as criminals stole cars, robbed stores and got sent to Mississippi river. Then there is a carnival mammal called fisher-- a specie of weasel, once doing pretty well in Hudson River in the north New York, after as almost being driven to extinction to 1930s. Now researchers can track fishers, treating them like criminal and fingerprint them, which is quite trick. Since fisher don’t have fingers, but their little pawns do have pattern that is unique to each individual. There is only carnival known to have such discernable prints. Well human print consist of ridges, fish fingerprint are pattern of dots. And dots stand computer software used to compare with human fingerprint. So scientists from wild life conservation society teamed up with experts from New York State department of criminal justice to develop a new technique to analysis and compare fish print, lead to more accurate population estimates. The fisher is wondering food bait box leave print sign on the popcorn again, which someone say it is virtually identical to criminal justice system.
