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 shortsightedness 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 shortsighted.”
67. Babies born in summer are more likely to be shortsighted ____________.
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
68. 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
69.From what Professor Daniel O’Leary says we can conclude that ___________.
A. there is no evidence that shortsightedness 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 shortsightedness
D. he tries to give the cause of why light exposure affects sight
70.The underlined word “vulnerable” in the passage probably means __________.
A. easy to be harmed B. resistant
C. protective D. changeable
Anthony was sad. He was, as he put it, “not very bright” and couldn’t win the attention of his very wealthy parents, who preferred his “clever” older brother. At age 8, Anthony was sent away to a boarding school in his native England, even though he screamed and pleaded with（恳求）his parents year after year not to send him. “The thought was it would be good for me,” he recalled.
It was not. Anthony did badly in his studies, had few friends and was bullied for five years. “My teachers couldn’t have had a lower opinion of me,” he said. “I wasn’t even smart enough to rebel. The one thing I remember from the very earliest age was the desire to write. When I was 10 years old, I remember asking my parents to get me a typewriter for my birthday because I wanted to be a writer.”
Now, at 55, Anthony is one of the world’s most successful children’s book authors. His Alex Rider series has sold more than 5 million copies, and the eighth book featuring the young spy, Crocodile Tears, has come out.
The Alex Rider books tell the adventures of 14-year-old Alex Rider, an agent for the British intelligence agency M16.
Anthony says he doesn’t try to write for kids; it just comes out that way. “I have a feeling that it has something to do with purity and simplicity. I give as little information as is necessary to describe the room, the character in the room, and get on with the action,” he said.
The style has also made Anthony a successful writer of television shows for adults in Britain because, he says, writing books for kids is a lot like writing television for grown-ups: In both cases, it’s all about entertaining people with a good story.
Now, Anthony couldn’t be happier with his life. He sums up his success: “…you can be anything you want to be if you just believe in yourself. I do believe it completely.”Which of the following is true of Anthony?
| A．He was the beloved child of his family. |
| B．Although he is successful, he isn’t very happy. |
| C．He places more emphasis on the characters’ behavior in his stories. |
| D．Studying in a boarding school proved a good choice for him. |
At boarding school, Anthony’s teachers_____________.
| A．often criticized him |
| B．showed great concern for him |
| C．encouraged him to be a writer |
| D．thought little of his ability |
What would be the best title for the passage?
| A．Anthony’s popular books—Alex Rider series |
| B．Alex Rider, a popular character |
| C．Anthony, a successful children’s book author |
| D．Special writing style |
What advice does Anthony give to readers?

| B．Hardship teaches valuable lessons. |
| C．Internet is the best teacher. |
| D．Failure is the mother of success. |
Along with more than 300 other seniors, I marched into the stadium on the afternoon of May 10. The audience burst into deafening cheers, whistling and clapping.
It was as if a Hollywood superstar had walked on stage. And indeed, every single senior that day was a star of the once-in-a-lifetime moment—the commencement.
Seated, I waited anxiously for the opening address. As a foreign exchange student, I was not able to receive a diploma. However, I still had the wonderful feeling of being part of things. Like the other graduates, I was dressed in marron cap and gown(方帽长袍).
Our principal, Mr. Glover, delivered a short, warm greeting. The US national anthem followed and then, hands on chests, a solemn Pledge of Allegiance(对美国的忠孝宣誓).
Students who had excelled academically gave farewell speeches. Then came the core (核心) of the commencement. Hundreds of names were announced. Each graduate walked across the stage to receive his or her diploma from the principal. From the different cheers each graduate got, we had the funny sense that it was a kind of competition of who could cheer the loudest.
To be honest, the presentation of diplomas got boring. But it wasn’t boring for those receiving the diploma: they would treasure the moment the principal placed the sacred brown document in their hands for the rest of their lives.
A new page in the book of that person’s life had turned. They were glimpsing their futures: futures of challenge, hardship, perhaps loneliness too, which would take all of their courage.What’s the article mainly about?

The Taj Mahal (泰姬陵) is a love story, a sad and beautiful one. If it didn’t exist, we would easily imagine that the story of its construction was simply a fairy tale. Three hundred years ago, there lived an Indian emperor called Shah Jahan. His wife was a beautiful and bright woman whom he loved greatly. Her title was Mumtazl Mahal: its shortened form Taj Mahal, means “pride of the palace”. In the year 1630 this beloved wife of the emperor died. He was so brokenhearted that he thought of giving up his throne. He decided out of his love for his wife, to build her the most beautiful tomb that had ever been seen.
He summoned the best artists and architects from India, Turkey, Persia and Arabia and finally, the design was complete. It took more than twenty thousand men working over a period of 18 years to build the Taj Mahal, one of the most beautiful buildings in the world.
The building itself stands on a marble platform 29 meters square and 6-7 meters high. Towers rise from each of the four corners. The Mahal itself soars another 61 meters into the air. It is an eight-sided building made of white marble.
The emperor planned to build an identical tomb of black marble for himself on the other side of the river connected by a silver bridge. However, his son put him into a prison in the palace before he could finish, and for the rest of his life, he could only gaze across the river at the tomb of his beloved wife.
