There are many older people in the world and there will be many more. A limeknown fact is that over 60 percent of the older people live in developing countries. According to the World Health Organization，by 2020 there will be 1 billion，with over 700 million living in developing countries.
It is a surprising fact that the population ageing is particularly rapid in developing countries. For example，it took France 115 years for the proportion of older people to double from 7 percent to 14 percent. It is estimated（估计） to take China a mere 27 years to achieve this same increase.
What are the implications（暗指） of these increased numbers of older folk？One of the biggest worries for governments is that the longer people live，the more likelihood there is for diseases and for disability. Attention is being paid to the need to keep people as healthy as possible，including during old age，to lessen the financial burden on the state.
Another significant problem is the need for the younger generations to understand and value the older people in their society. In some African countries，certainly in Asia，older people are respected and regarded as the ones with special knowledge. Yet traditions are fading away daily，which does not ensure the continued high regard of older people. As society changes, attitudes will change.
Much needs to be done to get rid of age discrimination (歧视) in employment. Lifelong learning programs need to be provided to enable older people to be active members in a country’s development.
Social security policies need to be established to provide adequate income protection for older people. Both public and private schemes are vital in order to build a suitable safety net.
To achieve equality in such matters will take considerable time and effort. One thing is sure：there is no time to be lost.
The proportion（比例）of older people________.
| A．is bigger in developed countries than in developing countries |
| B．is one seventh of the population in developing countries |
| C．will increase much faster in China than in France |
| D．will be sixty percent in developing countries by 2020 |

Ralph and Norton can grow to be 40 feet long and live in a tank as large as a football field.What are they? They’re the only two whale sharks at a North American aquarium .
You can see Ralph and Norton at the world’s largest aquarium, the new Georgia Aquarium in Atlanta.
The aquarium’s giant tanks hold eight million gallons of water and will be home to about 100,000 fish!
The aquarium was designed to look like a giant ship breaking through the waves.It has 60 different habitats from the sea and five galleries (展馆), each with a different theme.About 2.4 million visitors are expected to come each year.“We want to be the world’s most engaging aquarium.” Said Jeff Swanagan, the aquarium’s executive director.
Ralph and Norton arrived in June, 2005 from Taiwan.They were only 15 and 13 feet long, but they may grow to be more than 40 feet long! Whale sharks are the world’s largest fish.Three full-time vets will work there to make sure that Ralph, Norton, and all of the aquarium’s sea life stay healthy.Students from the University of Georgia will help run the aquarium and conduct research at the animal hospital.
The aquarium was paid for almost completely by a $ 200 million gift from Bemie Marcus, co-founder of Home Depot Inc, and his wife, Billi.“It’s going to be the most unique aquarium in the world,” said Marcus.Marcus said the aquarium was a “thank you” note to the city of Atlanta and the State of Georgia, where the Home Depot first opened for business.According to this passage, Ralph and Norton are ______.

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 |

War Horse is a historical story by Michael Morpurgo. It is written for kids ages 8 to 12. Now just sit and get through the introduction to the plot.
In 1914, a young horse named Joey is sold to a farmer. The farmer' s son, Albert, is thrilled. He cares for Joey. When the family begins to feel the financial impact of war, Albert' s father secretly sells Joey to an army officer named Captain Nicholls. Albert begs the captain to let him join the army. Albert is too young, but Nicholls promises to take good care of Joey for him.
Nicholls treats Joey well. Though Joey still remembers Albert, he grows to like his new master. He develops a friendship with another horse, Topthorn., who belongs to Nicholls' friend, Captain Stewart. The horses and men are shipped overseas for battle. They soon face their own battle in France, and Captain Nicholls is killed.
A young soldier named Warren becomes Joey’s new owner. Joey and Topthorn do well in battle, but the Germans capture Warren and Stewart and their horses. The horses' duty of pulling carts full of wounded German soldiers earns them praise. An old farmer and his granddaughter, Emilie, dote on the horses as well. When the German army moves out of the area, Emilie and her grandfather keep the two horses. Joey and Topthorn are content to work the farm until another band of soldiers takes them. They become workhorses under bad conditions. Joey is very upset when Topthorn dies of exhaustion.

The famous director of a big and expensive movie planned to film a beautiful sunset over the ocean, so that the audience could see his hero and heroine in front of it at the end of the film as they said goodbye to each other forever. He sent his camera crew out one evening to film the sunset for him.
The next morning he said to the men, “Have you provided me with that sunset?”
“No, sir,” the men answered.
The director was angry. “Why not?” he asked.
“Well, sir,” one of the men answered, “we’re on the east coast here, and the sun sets in the west. We can get you a sunrise over the sea, if necessary, but not a sunset.”
“But I want a sunset!” the director shouted. “Go to the airport, take the next flight to the west coast, and get one.”
But then a young secretary had an idea. “Why don’t you photograph a sunrise,” she suggested, “and then play it backwards? Then it’ll look like a sunset.”
“That’s a very good idea!” the director said. Then he turned to the camera crew and said, “Tomorrow morning I want you to get me a beautiful sunrise over the sea.”
The camera crew went out early the next morning and filmed a bright sunrise over the beach in the middle of a beautiful bay. Then at nine o’clock they took it to the director. “Here it is, sir,” they said, and gave it to him. He was very pleased.
They all went into the studio. “All right,” the director explained, “now our hero and heroine are going to say goodbye. Run the film backwards so that we can see the ‘sunset’ behind them.”
The “sunset” began, but after a quarter of a minute, the director suddenly put his face in his hands and shouted to the camera crew to stop.
