Everything on Earth that scientists can see, measure or study is made of atoms and atoms are named by what types of elements (元素)they are. You probably know the name of many elements, such as oxygen or hydrogen. In any case, elements are everywhere: You, your -shoes, your desk, cars, water and air are all made of elements.
Now, there's a new kind on the block： copernicium.
This element was officially named on February 19，but the element itself isn't new. German scientists made and observed it in 1996. But in the 14 years since then, other scientists have been working to study and validate (证实)the original findings. Validation is an important part of the scientific process because it shows that a scientific discovery was not a mistake.
All that hard work finally paid off when the element finally received its name, copernicium, from the International Union of Pure and Applied Chemistry. Copernicium is named in honour of Nicolaus Copernicus (哥白尼)，a 16th century Polish scholar who proposed that the earth moves around the sun and that the earth turns on its own axis.
Scientists organize all the elements on a chart called the Periodic Table. Each element gets a symbol and its own number, and copernicium gets the symbol Cn and the number 112. This number means that inside every atom of copernicium are 112 protons (质子). The lightest element hydrogen has only one proton inside each atom. Its 112 protons make copernicium the heaviest known element with a name. It was first observed by Sigurd Hofmann»a scientist in Germany. In 1996, Hofmann and his team had to figure out a way to get all the protons together and stick. They used a machine that can speed up atoms up to 10 percent the speed of light. After a week of working on these high-speed collisions(碰撞)，Hofmann's team found copernicium even though it quickly disappeared.
Now, 14 years after Hofmann's experiment, other scientists are able to make copernicium and validate Hofmann's original work. Scientists are excited about copernicium. If such a super heavy atom can be created, then even heavier elements might be waiting in the future. "One of the exciting things is, how far can we keep going?" says nuclear chemist Paul Karol.

Babies born in summer are more likely to become short-sighted in late life, a study has shown.
As many as a quarter of all cases of short-sightedness are caused by too great an exposure to sunlight in the first weeks of life, say eye experts.
They are advising all parents to put sunglasses on their babies during the first weeks.
Scientists had already established that over-exposure to sunlight caused short-sightedness in animals.
Researchers who compared the months in which babies were born with whether they needed glasses later on say the principle also applies to humans.
A study of almost 300,000 young adults─the largest of its kind─showed that those born in June and July had a 25 per cent greater chance of becoming severely short-sighted than those born in December or January. Research leader Professor Michael Belkin, of Tel Aviv University, said it was because prolonged illumination(光照) causes the eyeball to lengthen, causing short-sightedness.
Hence the more light a newborn is exposed to, the more the eyeball lengthens and the worse the short-sightedness will be.
The mechanism which lengthens the eyeball is associated with levels of melatonin(褪黑激素), a pigment (色素) which protects the skin against harmful rays of the sun.
In young babies not enough melatonin is released as protection, meaning they are more vulnerable to sunburn and changes to eyeball shape.
Sight expert Professor Daniel O’Leary, of Anglia Ruskin University in Cambridge, said “At the moment we don’t know the precise cause of why light exposure affects sight, but the evidence seems to prove that it is one of the reasons for people becoming short-sighted.”
55. Babies born in summer are more likely to be short-sighted ____________.
A. because the summer sun is too strong for babies
B. because babies born in summer have lengthened eyeballs
C. if they are exposed to much sunlight in the first weeks after they are born
D. if parents don’t know a proper way to protect their babies’ eyes
56. Melatonin is a kind of material to ___________.
A. prevent the eyes from becoming near-sighted
B. protect the skin from harmful sun rays
C. make our body strong
D. protect babies’ eyes from summer sun
57. From what Professor Daniel O’Leary says we can conclude that ___________.
A. there is no evidence that short-sightedness is related to exposure to sunlight
B. whether light exposure affects sight still needs to be further proved
C. he believes that light exposure can cause short-sightedness
D. he tries to give the cause of why light exposure affects sight
58. The underlined word “vulnerable” in the passage probably means __________.
A. easy to be harmed B. resistant
C. protective D. changeable
Weighed down（压得喘不过气来） by study? Pushed to the limit by the fast pace of life? Frightened by the possible war? Well, you’re not alone. Men and women in France are seeking relief using the world’s best medicine─laughter.
In the past year, more than 25 laughter clubs have been set up across the country. People of all ages release their stress with an hour of group laughs. “People telephoned me and said they have forgotten what it is to laugh. They want to find a place where they can escape all their problems for a while. So they come,” said 40-year-old Jocelyn Le Moan. She usually takes a class of around 60 people through a series of laughter techniques.
Her pupils range from teenagers to 70 years old, but most are middle-aged white collars seeking 60 minutes of relaxation at the end of a busy day.
Le Moan takes them through the “Lion Laugh” and the “Laugh Contest”, where participants “speak” to each other in different ways. And instead of talking, they break into fits of laughter. At the end there are 15 minutes of “meditation”（沉思）,when they lie on their backs and let the laughs burst out of their mouths.
“I love it. It’s an experience that has changed my life. Through it I rediscovered the child’s laugh inside me,” said Romain Jourffroy, 24.
Like Jourffroy, many laughter club members find themselves changed into children again, and why not? The average preschooler laughs up to 400 times a day. The average adult only a sad seven to fifteen.
The physical benefits of laughter are already well-recognized. Doctors say the act of laughing releases good chemicals into the blood-stream, while the quick breathing that accompanies it helps massage（按摩）the digestive organs and strengthens the heart.
“A full hour is like having your insides go jogging! One finishes out of breath, but feels revitalized (产生新活力). And on top of that, you’ve had a laugh,” said doctor Alexisd Estaing.
And many participants in Paris also emphasize the psychological benefits. They believe that laughter is a way of making oneself feel more confident.
“Maybe it is because we are surrounded by so many troubles that we feel the need to keep laughing,” said Anne Maurigiano, a 29-year-old filmmaker.
51. From the passage, we can conclude the following but __________.
A. Jocelyn Le Moan is a teacher of the club.

The plane journey from Papa Westray to Westray in the Orkney Islands takes just 96 seconds, covering a distance of little over a mile. Six teenagers are to take the Loganair service to Westray Junior High after the local ferry (渡轮) service stopped. They are all aged 13-14 and will be flown to and from school until the end of the year when the ferry is scheduled to return.
Papa Westray had a population of just 70 and no secondary school. Westray, home to more than 600 residents, has around 70 pupils at the Junior High and nine full-time teachers. The school provides education to Standard Grade level but pupils choosing to study for their Highers must travel to the Orkney capital Kirkwall.
The students will fly to Westray each Tuesday and stay with host families for two nights before catching a return flight on Thursday. Loganair operating the eight-seater service has changed its schedule to ensure the children get to school on time. The company says the flight, with an average flight time of 96 seconds, is the shortest in the world.
Jonathan Hinkles, the commercial director, said, “While it is a popular tourist route for many visitors to Scotland, it’s also an important lifeline to those residents who live, work or do business in the Orkneys and it will make all the difference to ensuring those children who live on Papa Westray can continue their schooling throughout winter.” Willie McEwen, acting head teacher at Westray Junior High, said, “we are delighted that Loganair has come forward with this solution. Our children will enjoy the flying especially as, at this time of the year, it can be quite dangerous on the boat. ”
83. Which of the following is TURE according to the passage?
