They may be so small that they can crawl along the edge of a coin,but the endangered status of the Partula gibba snails means soon they may not be visible at all.
The critically endangered snail,which is(41)Dbigger than a pin head at birth,is facing(42)Jafter a failed farming experiment almost wiped out its number in its native Pacific islands.When the predatory (食肉的)rosy wolf-snail from Florida was(43)Gto the islands in 1974 in an attempt to control land snail numbers,it instead fed on tree snails,including the tiny Partula gibba ones.
Now British conservationists are battling to save the tiny creature.Marwell Zoo in Hampshire,England is home to 123 of the world's remaining 306 Partula gibba snails.
This year,the zoo will release some of the snails into reserves on the Pacific islands.The snails will then be closely(44)Funtil they are released into the wild to look after themselves.
Snail keeper Geoff Read at Marwell Zoo is deeply(45)Babout the fate of the snails."i'm looking at a(n(46)Adying in front of me and to think these snails could become extinct in my lifetime is(47)Esad,"he said.
"I know they are only snails,and i hate to say that,BUT because they are not cute (可爱的) and fluffy (毛茸茸的),people do not seem to care.These animals are rare."added the keeper,who called for responsibility to be taken"very (48)I."
But there seems to be some good news.The International Partula Conservation programme has plans to reintroduce the snails into the wild,so there could be hope for the future."There home there is like a bio-security room and the environment is key to their(49)H."

The man paid(21)Cattention to all this,but the whisper and laughter began go get to him.He looked one of the(22)Amen straight into the eye,placed his hand beneath the(23)Band asked,"This?"
   With that the young men all began to laugh out loud.The man he had(24)Dsaid,"Hey,sorry man,but we were just commenting on how(25)Byour little pink ribbon looks against your blue jacket!"
   The middle-aged man(26)Ainvited the joker to come over to his table,and politely seated him.(27)Cas he was,the young guy had to,not really sure why.In a(28)Avoice,the middle-aged man said,"I wear this ribbon to bring(29)Dabout breast cancer.I wear it in my mother's(30)B."
"Oh,sorry.She died of breast canner?"
"No,she didn't.She's alive and(31)A.But her breasts nourished me as a baby,and were a soft(32)Aplace for my(33)Cwhen I was scared or(34)Bas a little boy.I'm very grateful(35)Dmy mother's breasts,and her health."

4.There is a lot of talk these days about how kids should be interested in science.Here's an area of science for everyone,and these cool new books might inspire you to discover your inner scientist.
Scaly Spotted Feathered Frilled by Catherine Thimmesh,58 pages,ages 9-12
    Seeing a picture or a model of a dinosaur,do you wonder how anybody knows what they look like?After all,nobody has seen a living dinosaur.This book explains how scientists and artists work together to re-create dinosaurs.As scientific discoveries have been made,the models have changed.Scientific tests may one day expose what a dinosaur's coloring was,but now artists have to use their imagination to determine how these huge creatures looked.
Beyond the Solar System by Mary Kay Carson,128 pages,ages 10-13
    This book takes readers back to the beginnings of space exploration-thousands of years ago,when people began star observation-and forward to today's search for planets in distant parts of the Milky Way.Along with history lessons,readers get 21 activities,such as making a black hole and creating a model of Albert Einstein's universe using a T-shirt.The activities are perfect for cold winter days.
Ultimate Bugopedia by Darlyne Murawski and Nancy Honovich,272 pages,ages 7 and older
    If you're always on the lookout for butterflies,this book is for you.Hundreds of color photos of common and unusual insects fill this hardcover.There are fascinating stories related to the photos.For example,do you know an insect feeds on the tears of Asian cattle?There's a question-and-answer section with an insect scientist and advice on how to help preserve endangered insects.
Journey Into the Invisible by Christine Schlitt,80 pages,ages 9-12
If you use a magnifying(放大的)glass,you know a leaf looks quite different.This book explains what microscopes do and then shows what happens to things around the house when watched with this amazing scientific tool.The bacteria in your mouth,when magnified 20,000 times,look a bit like swimming pool noodles.Fascinating photos are paired with suggestions about how to learn about the world around you,just by looking a little closer.

20.The most widespread fallacy(谬论)of all is that colds are caused by cold.They are not.They are caused by viruses passing on from person to person.You catch a cold by coming into contact,directly or indirectly,with someone who already has one.If cold causes colds,it would be reasonable to expect the Eskimos to suffer from them forever.But they do not.And in isolated arctic regions explorers have reported people are free from colds until they come into contact again with infected people from the outside world by way of packages and mails dropped from airplanes.
During the First World War soldiers who spent long periods in the trenches(战壕),cold and wet,showed no increased tendency to catch colds.
In the Second World War prisoners at the Auschwitz concentration camp,naked and starving,were astonished to find that they seldom had colds.At the Common Cold Research Unit in England,volunteers took part in experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time.After taking hot baths,they put on bathing suits,allowed themselves to be with cold water,and then stood about dripping wet in a drafty(通风良好的)room.Some wore wet socks all day while others exercised in the rain until close to exhaustion.Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
If,then,cold and wet have nothing to do with catching colds,why are they more frequent in the winter?Despite the most pains-taking research,no one has yet found the answer.One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times,and this makes it easier for cold viruses to be passed on.

19.Parents who smoke often open a window or turn on a fan to clear the air for their children,but experts now have identified a related threat to children's health that isn't as easy to get rid of:third-hand smoke.
That's the term (36)C to discuss the invisible yet poisonous mixture of gases and particles(颗粒) clinging(依附) to smokers'hair and (37)B,not to mention cushions and carpeting,that stays long after second-hand smoke has cleared from a room.The remaining (38)A heavy metals,carcinogens(致癌物) and even radioactive materials that young children can get on their hands and take in,(39)A if they're crawling or playing on the floor.

"Everyone knows that second-hand smoke is bad,(43)A they don't know about this,"said Dr.Jonathan P.Winickoff,the lead author of the study and an assistant professor of Pediatrics at Harvard Medical School.
"When their kids are (44)B the house,they might smoke.Or they smoke in the car.Or they settle the kid in the car seat in the back and(45)D the window and smoke,and they think it's okay because the second-hand smoke isn't getting to their (46)C.We needed a term to describe these tobacco toxins(毒素)that aren't (47)A."
The study reported on (48)B towards smoking in 1,500households across the United States.It found that the vast majority of both smokers and nonsmokers were (49)D that second-hand smoke is harmful to children.Some 95percent of nonsmokers and 84percent of smokers (50)B with the statement that"inhaling smoke from a parent's cigarette can(51)A he health of infants and children".
But(52)C fewer of those surveyed were conscious of the(53)B of third-hand smoke.Since the term is so new,the researchers asked people if they (54)A the statement that"breathing air in a room(55)B  where people smoked yesterday can harm the health of infants and children".
Only 65percent of nonsmokers and 43percent of smokers answered yes.
