A baby born in India has been declared the world's seven billionth person by child rights group Plan International. Baby Nargis was born at 07:25 local time (01:55GMT) in Mall village in India's Uttar Pradesh state. Plan International says Nargis has been chosen symbolically as it is not possible to know where exactly the seven billionth baby is born. In addition to baby Nargis in India, Bangladesh, the Philippines and Cambodia have all identified seven billionth babies. The United Nations estimated that on Monday 31 October, the world's population would reach seven billion.
Populations are growing faster than economies in many poor countries in Africa and some in Asia. At the same time, low birth rates in Japan and many European nations have raised concerns about labor shortages.
Population experts at the United Nations estimated that the world reached six billion in October 1999. They predict nine billion by 2050 and ten billion by the end of the century. China's population of one and a third billion is currently the world's largest. India is second at 1.2 billion. But India is expected to pass China and reach one and a half billion people around 2025.
India will also have one of the world's youngest populations. Economists say this is a chance for a so-called demographic dividend. India could gain from the skills of young people in a growing economy at a time when other countries have aging populations. But economists say current rates of growth, although high, may not create enough jobs. Also, the public education system is failing to meet demand and schooling is often of poor quality. Another concern is health care. Nearly half of India's children under the age of five are malnourished(营养不良).
Michal Rutkowski, the director of human development in South Asia at the World Bank, says reaching seven billion people in the world is a good time for a call to action. He says, “I think the bottom line of the story is that the public policy needs to become really, really serious about sex equality and about access to services—to fight against malnutrition, and to provide for access to health services, water and schooling.”What is true about the world's seven billionth person?

Research suggests that a newly-identified gene known as insomniacs(失眠症患者) may play a role in keeping us asleep. By cloning and testing this gene in about 21,000 fruit flies, Rockefeller University researchers say they have discovered an entirely new mechanism (机制) by which sleep is controlled.
By studying these flies, the researchers discovered that mutations(变异) in the insomniac gene were associated with a great reduction in sleep. While a typical fruit fly slept for an average of 927 minutes a day, the mutant flies slept for just 317. They also slept for shorter periods of time, and slept and woke more frequently.
“The results showed a great loss of both the time that the flies’ sleep lasted and their ability to remain asleep after they slept,” says researcher Nicholas Stavropoulos.
The researchers also examined the link between sleep and lifespan, finding that flies with mutations to the insomniac gene lived only about two-thirds as long as unchanged flies. But when the scientists removed insomniac only in neurons（神经细胞）---allowing it to remain in the rest of the flies’ bodies---this difference disappeared; the resulting animals slept poorly but lived just as long.
“This suggests that reduced sleep can be ‘uncoupled’(分开) from reduced lifespan, supporting the idea that some interruptions of sleep do not affect overall health, at least as far as lifespan is concerned,” Stavropoulos says.
Although flies and humans would appear to have little in common when it comes to lifestyle, scientists say that the mechanisms of sleep and wakefulness are likely to be quite similar.
“Sleep is a fundamental behavior in all animals, and it is poorly understood from a scientific standpoint, says Stavropoulos. This work could prove useful in understanding and treating sleep disorders”The text is mainly about____.
| A．the progress in cloning fruit flies |
| B．the methods of cloning fruit flies |

| D．could not fall asleep |
We can conclude from the text that________.

Ashley and Chris work in the same department designing postcards. Chris had a college degree in art and deeply felt that the degree of his designs was excellent. His last postcard showed the depth of a desert’s beauty and delights.
“It’s just a picture of the desert,” Ashley said. “Not deep at all.”
“Some people desire seeing beauty,” Chris replied. “Mine delivers that”.
Ashley laughed and said, “well, that depends on what you think beauty is.”
Days later, someone delivered a letter to Ashley. The letter said, “You are worthy of the bad things that will come your way. You will know the taste of defeat, and I will destroy you.”
Ashley suddenly felt very cold. It was as if the room temperature had dropped 30 degrees. “Who would do such a shocking deed?” she wondered. “I will not let a simple letter defeat me.”
Just then, Chris came into the room and offered Ashley a piece of his sandwich.
“Try some,” he smiled widely. “It’s delicious.”
“Are you trying to poison me?” Ashley asked. Chris’s answer was delayed from confusion. “What’s your problem?” he asked.
The next day, Ashley brought a bat to use to defend herself. When Chris saw her bat, he joked, “Defend and win one for the team.”
Ashley took no notice of him. She spent the whole day reading self-defending books and placed her work on delay. “You can’t delay your work. Our job demands us to do our work on time,” Chris said. “We must meet the demands of our job.”
“You‘re not the boss,” Ashley replied. “Don’t make demands of me.”
Because Ashley failed to do her work, she was fired.
Chris glanced at Ashley’s empty desk and smiled.What kind of work did Chris and Ashley do?

What did Ashley think of the last postcard designed by Chris?
| A．Excellent |
| B．Too bad |
| C．It didn’t show the real beauty of the desert. |
