If you are no(not) a fan of cigarettes, you probably hold your breath (and) you hurry pass the smokers that hanging out in front of (the) office buildings, stores and restaurants. Smokers are banished outside because of the(a) growing number of cities concern(concerned) with the possible health effect of secondhand smoke A (have) ban of (banned) smoking in eating or(either these work) places (or) other such establishments. Turns out holding your breath might not (be) such a bad idea because of(delete) scientists at the University of Georgia have found (that)sidewalk smokers can generate more pollution than passing cars. Athens,Georgia is a major college town.And on the weekend, students are pass(packing, patched)shoulder and shoulder outside bars and restaurants. And since smoking is banned inside(of,这里似乎没有of) such locations, one(plenty) of those kids are parking out the (puffing up a) storm. That may the Georgia researchers wander(wonder) whether outdoor secondhand smoker could present health hazard(赞forerunner) in the zone(of its own). So the(they) measure the carbon monoxide level outside the hand for(harmful, a handful of) bars and restaurants because the(this) gas(gas’s) also find(found) in the(delete)car exhaust. The researchers counted the numbers(number) of the cars and the numbers(number) of smokers and they found the pollution was coming from thepeople not (the) tail pipes(tailepipes). So next time you stroll pass the ?punch the banishment(pass the bench(bunch) that's banished), take a deep breath and feelfree to run.

Pure Oxygen May Be Harmful In Emergency

Ambulance is rushing you to the emergency room and you are losing conscience. The medical grabs your face mask started to feed you stream of pure oxygen to cause damage to your brain? A new UCLA brain damage has been studying a growing body of research suggest that inhaling of pure oxygen is bad for you. The research did MRI brain scans to 14 kids each aged from 8 to 15. In one test was fed pure oxygen, in second 95% oxygen and 5% carbon dioxide. With the pure oxygen the kids breathing quicken and blood vessels constricted, preventing the oxygen from reaching the brain and heart. Then things got worse the hypothormos responded to emergency signals that the body was sending by dumping a massive flood of hormones or neuron transients into the blood stream, Which interfere with the heart ability to pump the blood and deliver oxygen, the worst thing in a crisis situation. But adding a little shadow of carbon dioxide calmed the hypothomos, the blood vessels relaxed, the surge of chemical danger stopped, because when it comes to oxygen, you can’t have too much of good thing.

（An）Ambulance is rushing you to the emergency room and you are losing conscience. The medical(medics, 实习医生) grabs your face mask started to feed you stream of pure oxygen to cause damage to your brain? A new UCLA brain damage has been studying（study is a part of） a growing body of research suggest(s) that inhaling of pure oxygen is bad for you. The research did MRI brain scans to 14 kids each aged from 8 to 15. In one test was fed pure oxygen, in second 95% oxygen and 5% carbon dioxide. With the pure oxygen the kids’ breathings quicken and blood vessels constricted, preventing the oxygen from reaching the brain and heart. Then things got worse the hypothalamus responded to emergency signals that the body was sending by dumping a massive flood of hormones or neuron transients into the blood stream, Which interfere with the heart ability to pump the blood and deliver oxygen, the worst thing in a crisis situation. But adding a little shadow(shard 碎片) of carbon dioxide calmed the hypothalamus, the blood vessels relaxed, the surge of chemical danger stopped, because when it comes to oxygen, you can’t have too much of （a）good thing.

Know(No.) clownfish don't communicate by honking booboos noses(bob’s noses).  But they do communicate according to Eric Parmentier at the University of L B( Liege in Belgium). Parmentierand his colleagues use high-speed video and x-ray(x-rays)to catch clownfish in the act (of) making the chirps and pops. They use to warn of(off)rivals or lure mates which sounds like the crikey(cricket)at (an) old door hinge, listen.... The clownfish like many other(of the) picy(pricy) brander one use (the)sound(sounds) creatively, but make them a unique way according to the(delete) Parmentier’s paper in Science. Whereas most of other fish(fishes) use(delete)swim bladders to(delete) rap their bone together to vocalize, and haering (hearing)like (to) suck through(theair through) the sofet(soft) gas and serious(seriously) blow (it) out in the air(less) rapidly.Clownfish prefer to raise their heads, shuffle the bones in their mouth andclose their jaws. Slamming teeth together produces the noise that than radiated(by) the jaws (of)all 27 varieties of the species. It's not exactly the tears of the clown - fishmore like the teeth grinding (of) the clownfish to(clownfishes) pick up a line, butit's still music to their mates.

怎么没有把听力的mp3上传上来啊]？我觉得还是每期都把听力的mp3传上来，这样教育网的人可以更容易听一些！

woodmanUID: 161906

我只能压缩了上传，呵呵，如果大家需要，那我每次上传压缩版好了。

woodmanUID: 161906

6月1日的音频上传了，但前几天的恕我心有余力不足了，附件大小不能超过1048.576kb，压缩之后比这个上限值大，传不上。呵呵

谢谢修改:handshake
有几处不明白意思:confused:
honking:confused:  bob’s noses
the cricket:confused:  at an old door hinge
many other of the pricy brander:confused:  one
It's not exactly the tears:confused:  of the clown - fishmore like the teeth grinding of the clownfishes pick up a line:confused:
请指教:)
