and my dictation today is as follows:

In 1986, an explosion at the Chernobyl nuclear power

plant blanketd the surrounding area with radioactive

fallout. Now scientists who've been tracking that

disaster toll of adding a new victim to their list----

birds that near live the reactor.The interesting thing

is not all the birds near the Chernobyl have been

decimated by radioactivity,only those that are brightly

colored,migrate long distances or lay big eggs,all of

which require antioxidant molecules.The researchers

examined birds from 57 species, they found that those

with bright plumes such as orioles and blue tits, were

harder hit by radiation than the drab neighbors such as

coal-tits and chaffinches.The same was true for birds

that tend to travle and like to lay large eggs.That

pattern suggests that antioxidant molecules play an

important role in how birds handle radioactivity,

because antioxidants can protect animals against nasty

chemicals like those that spilt from the damaged

reactor.But brightly colored birds use up their

antioxidants producing those flashy red,yellow and

orange pigments,so the Chernobyl meltdown may being the

bright a bust for birds,well, being dull is the thing

to do.

In 1986, an explosion at the Chernobyl nuclear power plant blanketed the surrounding area with radioactive fallout. Now scientists who have been tracking that disaster’s toll have added a new victim to their list--birds that live near the reactor. The interesting thing is not all the birds near Chernobyl have been decimated by radioactivity, only those that are brightly colored, migrate long distances or lay big eggs--all of which require antioxidant molecules. The researchers examined birds from 57 species. They found that those with bright plumage such as orioles and blue tits were harder hit by radiation than their drab neighbors such as coal-tits and chaffinches. The same was true for birds that tend to travel and like to lay large eggs. That pattern suggests that antioxidant molecules play an important role in how birds handle radioactivity because antioxidants can protect animals against nasty chemicals like those that spilled from the damaged reactor. But brightly colored birds use up their antioxidants producing those flashy red, yellow and orange pigments. So the Chernobyl meltdown may being bright a bust for birds while being dull is the thing to do.

最后一句话不懂，谁能解释一下? 为什么may后面跟being？

July 19, 2007: 60-Second Science   Mosquito Legs' Structure Allows Amazing, Er, Feats   

Mosquitos are summertime menace. But they are also a marvel on mechanical engineering. They can stick to your skin, cling to a wall and even walk on water. Now a team of physicsts from Canada and China has figured out how they do it--the tricks and the feat. First off, mosquitos have tiny hooks on their tootsies which they use to latch onto skin. And they hang onto walls as the same way geckos do, using hairy little foot pads that let them stick to surfaces, like they're wearing velcro socks. But it's their water-walking that maybe their most remarkable , Er... feat. To dance across on a pond or to stand at top of a polo, mosquitos use their superhydrophobic legs. These limbs are so phenomenally water repelling that each one can effectively support 23 times the insect's weight. At least that's what the physicist discover when they took a single mosquito leg and measured the force needed to push into a cup of water. The reason the leg is so hydrophobic is because there coated with tiny feather like scales but there in turn covered by even tiny ribbing. So next time you swat a skeeter, remember, you just wag the wonder of nature.

Mosquitos are summertime menace. But they are also a marvel on mechanical engineering. They can stick to your skin, cling to a wall and even walk on water. Now a team of physicsts from Canada and China has figured out how they do it--the tricks are in the feat. First off, mosquitos have tiny hooks on their tootsies which they use to latch onto skin. And they hang onto walls as (no 'as') the same way geckos do, using hairy little foot pads that let them stick to surfaces, like they're wearing velcro socks. But it's their water-walking that may be their most remarkable , Er... feat. To dance across on a pond or to stand at top of a polo, mosquitos use their superhydrophobic legs. These limbs are so phenomenally water repellent that each one can effectively support 23 times the insect's weight. At least that's what the physicist discover when they took a single mosquito leg and measured the force needed to push it into a cup of water. The reason the leg is so hydrophobic is because there coated with tiny feather like scales but there in turn covered by even tinier ribbing. So next time you swat a skeeter, remember, you just wag the wonder of nature.


PS: dcb has done a great job, really!! ^_^

Mosquitos are summertime menace(s). But they are also a marvel on(of, thanks to yyhwzc)mechanical engineering. They can stick to your skin, cling to a wall and even walk on water. Now a team of physicsts from Canada and China has figured out how they do it--the tricks are(x) in the feat(feet). First off, mosquitos have tiny hooks on their tootsies which they use to latch onto skin. And they hang onto walls the same way geckos do, using hairy little foot pads that let them stick to surfaces, like they're wearing velcro socks. But it's their water-walking that may be their most remarkable , Er... feat. To dance across on(x) a pond or to(x) stand at top of a polo(puddle), mosquitos use their super-hydrophobic legs. These limbs are so phenomenally water repellent that each one can(could, I don't why but yyhwzc got the same with mine) effectively support 23 times the insect's weight. At least that's what the physicist(s) discover(ed) when they took a single mosquito leg and measured the force needed to push it into a cup of water. The reason the leg(s) is(are) so hydrophobic is because there(they are)coated with tiny feather like scales but there(x) in turn covered by even tinier ribbing. So next time you swat a skeeter, remember, you just wag the wonder of nature.

Good job by dcb and Visorz, only trifling differences left.
Btw, dcb, could you tell me how can you learn words like: tootsy, gecko, and velcro by heart?

Still one question left: can anyone explain the sentence
"The reason the leg(s) is(are) so hydrophobic is because there(they are)coated with tiny feather like scales but there(x) in turn covered by even tinier ribbing."
to me?
Thanks in advance.

Mosquitoes are a summertime menace. But they are also a marvel of mechanical engineering. They can stick to your skin, cling to a wall and even walk on water. Now a team of physicists from Canada and China has figured out how they do it. The trick is in the feet. First off, mosquitoes have tiny hooks on their tootsies which they use to latch onto skin. And they hang on to walls the same way geckos do, using hairy little foot pads that let them stick to surfaces like they’re wearing Velcro socks. But it’s their water-walking that may be their most remarkable feet. To dance across a pond or stand on top of a puddle, mosquitoes use their super hydrophobic legs. These limbs are so phenomenally water repellant that each one could effectively support 23 times the insect’s weight. At least that’s what the physicists discovered when they took a single mosquito leg and measured the force needed to push into a cup of water. The reason the legs are so hydrophobic is because they are coated with tiny feather like scales that are in turn covered by even tinier ribbing. So next time you swat a skeeter, remember, you just whacked (很奇怪，这边明明听到的是whacked, 但是从语法上讲应该是whack才对，不知为何?) a wonder of nature.

to me?


The reason the legs are so hydrophobic is because they are coated with tiny feather like scales （that are in turn covered by even tinier ribbing. ）后面括号里的是用来修饰scales的，这样好理解了吗？
