The city I live is located in the heart of America. It is much smaller than Beijing. You may call it a town. But acutually it is the fourth largest city in the state.  More than one third of its residents are students, I means colleage students. If you want a journalism major, the state flagship university welcome you. of course this is a nig university, other majors are also crowded with students. But the journalism school hold the best reputation in America.

Hamsters suffering from the laboratory version of jetlag get back to normal faster when given E.D. drugs.

Scientist in Argentina has found that hamster recover more quickly from jetlag when they take drug before the flight------Viagra. Ok there are maybe a lot of things wandering right now like is  jetlag a problem for hamster or where the hamster going with their exercise wheels and (?retail) the function prescriptions. Here is what we know jetlag happen when your body clock doesn’t agree with on the wall because you cross a couple of time zones. The mismatch can be (?graged)in disoriented. Even disrupt your sleep cycle until you able to reset internal time pace. Would the same thing happen to the hamsters when the scientist book them on the (…………..)      laboratory equivalent turn on the light six hours early is then take jetlag a little ?  while to figure out when to start running in the exercise wheels which they usually do after dark. What the Argentina researches found is that hamster given by Viagra a night before the time change recover faster than hamster do without the drug whether similar treatment would provide relief to very well traveler this experiment probably been in a ? done but not reported.

PS:E.D. drugs-------Erectile Dysfunction drugs
      Sildenafil citrate, sold under the names Viagra
      Viagra pills are blue and diamond-shaped
            Viagra---伟哥:confused: ？

Scientists in Argentina have found that hamsters recover more quickly from jetlag when they take a drug before the flight------Viagra. Ok there maybe a lot of things you’re wondering right now like is jetlag a big problem for hamsters or where these hamsters going with their exercise wheels and erectile function prescriptions. Here is what we know, jetlag happens when your body clock doesn’t agree with the clock on the wall because you’ve crossed a couple of time zones. The mismatch can leave you gawky to disoriented, and even disrupt your sleep cycles until you’re able to reset your internal time piece. Well the same thing happens to the hamsters when scientists book them on the redeye from Venusaris to Bucharest or laboratory equivalent turning on the light six hours early. It then takes the jetlag a little feeble as a will to figure out when to start running out the exercise wheels which they usually do after dark. What the Argentinian researchers found is that hamsters are given the Viagra the night before the time change recover faster than hamsters that do without the drug. Whether similar treatment would provide relief to weary will travelers is experiment that’s probably been inovertly done but not reported.

红色的地方听不到．．．请大家指正:)

Scientists at Argentina have found hamsters recover more quickly from jetlag when they take drug before flight, by error. Ok. Maybe a lot of things you are wondering right now like problems from hamster or where is this hamster going there, exercise will retell this function description. Here is what we know. Jetlag happens when your body clock does not agree with clock on the wall because you cross a couple of time zones. The mismatch can be gawky or disoriented, even disrupt your sleep cycle until you are able to reset your internal time piece. Well, the same thing happened to the hamster when scientist pose them from Venusaris to Bucharest or laboratory equivalent to turning the light six hours early, then it take hamster for a while to figure out when to start running their exerciser wheel which they usually direct dark. While the Argentina researchers found the hamster given by drug might perform time change recover faster than hamsters do without drug. The similar treatment will be provided to relieve worldwide travelers. This experiment is probably greatly done, but not reported

I come to gter site because maybe some day I need to take toefl. I am an alien in America and it is generally believed that education makes difference at all levels. Special training is in need for me. After several decades of English learning, my kid still laughs at my poorly structured foreign language. It is really embarassing!
My listening is actually not as good as you thought. I have to listen many times to complete the dicatation. That's why I force my self to go with you guys. I believe after this process in a couple of weeks, I will gain a significant leap in mastering English language.
Anyway gter is a great site for people like you and me to practice intensice English with determined purposes. Thank you for your encouragement. I like to share with you and to be appreciated. And everyone has such intention, I assume.
Good harvest for every hard sower.

5月21日的听抄，在xixihehe0167上的修改
You may have heard that exposing kids to a certainamount of dirt and germs when they were young can make them less prone toallergy later in life. Now comes news that bacteria toxin(toxins)can do the same. Endotoxins(Endotoxin) is a protein thatshed (that’s shed) by certain bacteriawhen they were damaged or dead which sounds unpleasant. But researchers at the Arizona RespiratoryCenter in Tucson have found that kids who grow up inhouses with plenty of endotoxins or actually less likely to develop eczema orwheezing by the age of 3. Their results will being(be)presented this week at the American Thoracic Society Conference in San Francisco. Mustyhomes with leaking walls are likely harbor for endotoxins. But (all) our houses were carpeting or those are more than30 years old. But perhaps you shudder(you’re shocked)at the thought you and your loved ones tiptoeing though(through)the toxins on the path to good health. Then you might be interested inanother study being presented in this meeting. Scientists from the universityof Seoul find that washing your laundry in really hot water about 140 degrees Fahrenheiteliminates more dust mites dog dander and pollen than warm water. News thatchilly makes all you feel is under out there. Hark(听，倾听) withrelief.

Pure Oxygen May Be Harmful In Emergency
A small study found that a stream of oxygen with some carbon dioxide included may be a better emergency therapy than pure oxygen alone.


Ambulance is rushing into the emergency room and you losing consciousness. The medical grasp a face mask start feeding you’re a stream of pure oxygen to cause damage to your brain? A new UCLA brain damaging study was a part of a growing body research that suggest inhaling pure oxygen is bad for you. The researchers did MRI brain scan to14 kids age 8 to 15 in one test they were ? pure oxygen in the second 95% oxygen and 5%carbon dioxide. With pure oxygen the kid is 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 was 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 situation. But adding a little (?shut) of carbon dioxide calm the hypothalamus. The blood vessels relaxed, and the surge of dangerous chemical stopped. Because when to come to the oxygen you can have too much of good things.

Magnetic resonance imaging (MRI) uses radio waves and a strong magnetic field rather than x-rays to provide remarkably clear and detailed pictures of internal organs and tissues. This technique has proved very helpful to radiologists in diagnosing tumors of the brain as well as disorders of the eyes and the inner ear. It requires specialized equipment and expertise and allows evaluation of some body structures that may not be as visible with other imaging methods.

请指正:)

The hypothalamus responding to emergency signal body would send identical massive of flood of hormones and neurotransmitter to blood string, which interfere with heart’s ability to pump oxygen and deliver oxygen, worsen the critical situation. But add a little shock of carbon dioxide, calm the hypothalamus, the blood vessel relaxed, and surge of dangerous chemical stopped. Because when it comes to oxygen, you can have too much of good things.
