The deep sea is one of the most mysterious places on earth. Scientists rarely go there. Those few do discover new species all of the time. Many places of the deepest parts of the ocean, where it's forever dark, can light up. Now, a teen's research has shown new light on how one of these swimming animals behaves in darkness.
The giant flashlight fish lives in the Indian Ocean as well as in tropical parts of the central and western Pacific. It lives at depths of up to 400 meters, (about 1,300 feet). But not always. Sometimes it lives in coral reefs in shallow waters. In those shallow waters, the blackish-blue fish comes out only at night. Reef-dwelling members of this species tend to be smaller than those living in deeper waters. Those biggies can grow to lengths of 35meters (14inches). That may not sound like a giant, but they are the largest of their type of fish.
The giant flashlight fish gets its name from a small glow-in-the-dark patch found in a packet of tissue under each eye, explains Caroline Edmonds. She is a 13- year-old student from Fountain Valley, Calif. There, she attends Talbert Middle School. She said that the eye pockets in these fish contain light-producing bacteria.
These bacteria and their host fish have built a relationship that helps both. The fish use the bacteria as a way to communicate with creatures around them. The bacteria gain nutrients from the fish and a safe place to live. When a fish wants to “ flash” its light, it turns the bacteria-filled pocket toward the outside of its body, Caroline explains. When a fish wants to hide its light, it turns the pocket back toward the inside. According to her data, the fish flash most often when they are being fed. They flash least often late at night, when they are resting.The deep sea is dark and mysterious, but _________

People are being invited to sit down to eat with their neighbors in a nationwide lunch party designed to promote community spirit. The Big Lunch is the idea of the Eden Project in Cornwall. It aims to persuade people up and down the country to hold street lunch parties.
Tens of thousands of vegetables, fruits and flowers were used to construct a giant 2,000-square-foot lunch invitation in London’s Convent Garden. More than 9,000 cauliflowers and 800 bananas were used.
According to the organizers, people who decide to take part in the activity will get support from large companies which will supply many of the necessities, including plants to be given out to people to grow. The organizers think that the Big Lunch is a great opportunity for people to get together and spend time with their neighbors, friends and families. Events like this also help build strong communities. People can show their talents, get over their embarrassment, shake hands and get to know their neighbors, and realize that the neighborhood where they live can be a great source of happiness and enjoyment.
The Eden Project’s leader, Tim Smith, says, “It’s a good way to face this recession. Imagine a day on which millions of us, throughout the UK, sit down to have lunch together with our neighbors in the middle of our streets, around our tower blocks, and on every patch of common ground. We’ll have cooked our own food, made our own entertainment, and created our own decorations. It will be a day to share bread with our neighbors, and put a smile on Britain’s face.”

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.
B. the members are mostly middle-aged white collars.
C. people always need some way to relax in life.
D. laugh freely and everything goes well.
52. The writer suggested that you should __________.
A. have a good laugh after a busy day

B. It can release good chemical into blood-stream.
C. It can make you feel self-confident.
D. It can cure the illness of people.
