In order to develop our interest in English. our school has set up several English clubs, among that the Radio Club is the most popular one. Every afternoon after supper, there are three students to run club. Students can play English songs, or read aloud English poems, essays, news, or story. I still remembered what happened when I hosted the programme for the first time two years ago. A week before it, I had searched the Internet for the later news, attractive topics and our loved English songs. Despite of good preparations, so nervous was I when I sat in front of the microphone that I felt my brain went blank. Thanks to the practice making before, I managed to calm down or concentrate. Several seconds later, I lost me in the broadcasting, really enjoying and appreciated it.

How long could you stand on Antarctic ice before your bare feet froze solid? A minute. Maybe two? If you’re an emperor penguin, you can do it for two months in cruel winds at as low as-75 degrees Fahrenheit1., but their special circulation acts as a kind of antifreeze to keep them warm enough.
Penguin legs and feet have evolved to lose as little heat as possible. Penguin feet preserve heat by restricting blood flow in really cold weather, keeping foot temperature just above freezing2.
Blood vessels to and from the feet are very narrow and woven closely together, cooling the blood from the body on the way to the feet and heating the blood as it returns to the body.3. .
This special ability is part of how penguins keep their eggs warm until they hatch. Each penguin egg’s father balances it on his feet and covers it with his very warm layer of feathered skin to keep it cozy while females are out feeding at sea.4.. If females haven’t returned with food by time the chicks hatch, male penguins feed their babies for a few days on a kind of "milk" made from special cells inside their throats.
5.Your hands get whiter during freezing weather because there 's less blood in them which has been redirected to the central part of your body to make sure vital organs stay warm.
A. Penguin legs work like a heat exchange system
B. Those naked bird feet may look extremely cold
C. Therefore, the male penguins must stay together in groups
D. However, parenting doesn't stop there for these devoted fathers
E. Emperor penguins also have the ability to 'recycle’ their own body heat
F. Feet get cool blood so there’s less heat to lose, while the body stays warm and comfortable
G. In fact. humans have the ability to restrict blood flow to their hands and feet in cold weather too
Babies’main food is rice cereal. But it is often poisoned. Studies have found that many brands contain measurable amounts of inorganic arsenic(无机砷),the most poisonous kind. It's not just nice: an August 2018 study tested 50 foods made for babies. including organic and nonorganic brands such as Gerber, Earths Best, and other popular labels, and found evidence of at least one dangerous heavy metal in every product. Fifteen of the 50 contained enough contaminants(污染物)to pose potential health risks to a child eating one serving or less a day.
Heavy metals can damage cognitive(认知的 )development in children, who are especially at risk because of their smaller size. Inorganic arsenic in drinking water has been found to lower the IQ scores of children by five to six ills. And as heavy metals accumulate in the body over time. they can raise the risk of cancer, diabetes and other physical conditions. Of course, finding you’re your favorite brand is contaminated is not a reason to panic. Low levels of exposure for short periods are unlikely to cause serious effects, but parents should focus on reducing the overall levels of these poisonous substances in their children's total diet to limit harm.
Heavy metals occur naturally on Earth and are present in soil and water. But pesticides(杀虫剂), mining and pollution increase their concentrations, and farming and food manufacturing processes can contribute even more.
Food makers are clearly of keeping baby food poison-free: roughly a third of the tested products did not contain worrisome metal levels. Some companies are already trying to look into the sources of contamination in their products and try to reduce them. More companies should follow. But the best chance of real change will come with laws. Currently there are no U. S rules on acceptable levels of heavy metals in baby foods.
The government and the food industry should unite to deal with the serious threat to our children.
