In a six-week study, experts found people who played online games designed to improve their cognitive(认知的) skills didn't get any smarter.
More than 8,600 people aged 18 to 60 were asked to play online brain games designed by the researchers to improve their memory, reasoning and other skills for at least 10 minutes a day, three times a week. They were compared to more than 2,700 people who didn't play any brain games, but spent a similar amount of time surfing the Internet and answering general knowledge questions. All participants were given a sort of I.Q test before and after the experiment.
Researchers said the people who did the brain training didn't do any better on the test after six weeks than people who had simply been on the Internet. On some sections of the test, the people who surfed the Net scored higher than those playing the games.
"If you're (playing these games) because they're fun, that's absolutely fine," said Adrian Owen, the study's lead author. "But if you're expecting (these games) to improve your I.Q., our data suggests this isn't the case," he said during a press briefing on Tuesday.
One maker of brain games said the company's games have been proven to boost brain power.
"Their conclusion would be like saying, 'I cannot run a mile in under 4 minutes and therefore it is impossible to do so," Aldrich said in a statement.
"There is precious little evidence to suggest the skills used in these games transfer to the real world," said Art Kramer, who was not linked to the study and has no ties to any companies that make brain training games.
Instead of playing brain games, Kramer said people would be better off getting some exercise. He said physical activity can spark(激发) new connections between nerves and produce new brain cells. "Fitness changes the building blocks of the brain's structure," he said.. It can be inferred that the online brain games mentioned in the text are_____________.
| A．costly | B．unreliable | C．illegal | D．effective |

Dear Editor,
I’m now busy in preparing for the Postgraduate (研究生) Entrance Exam. A few days ago, I happened to see some new guidebooks for those who want to take next year’s exam. With too many hopes and without taking it into too much consideration, I bought several that were written by some known for helping candidates (应试者) for master’s degrees.
What made me really angry was the starting discovery that the contents of those books were almost exactly the same as some I had bought before. There were only superficial (外表的) changes in their covers, with more attractive new titles and better designs. The contents were the same.
People say that the publishing industry is in a state of chaos (混乱) these days but I used to be doubtful abut that. I was of the opinion that only people of noble character, prestige (威望), and exceptional talent would produce books for higher education. But these editors are caring little about their readers.
I hope that authors and publishing houses will be more responsible for their readers. Don’t destroy the image that you have with your readers.The writer bought some guidebooks in order to ___________________________.
| A．write an essay on guidebooks | B．prepare for the entrance exam |
| C．give his students a lecture | D．send them to his good friends |
The writer was angry because _________________________________________.
| A．there were a lot of printing mistakes in the books that he had bought |
| B．the books were so expensive that he couldn’t afford any of them |
| C．he found the books he had bought were thin but of poor quality |
| D．the books had the same contents as what he had bought before |
In the writer’s opinion, publishers should be _____________________________.
| A．responsible | B．kind-hearted | C．hard-working | D．creative |
It was a quiet village in which there was a military camp. It was far from the towns and cities and there were some high mountains around. Of course it was a good place for training the new soldiers. But it was difficult for the young men to go outside. Mr. White, an officer of forty, was strict with them and he hardly let them leave the camp.
Once Mr. White was ill in bed. He couldn’t work and a young officer, Mr. Hunt, began to train the new soldiers instead of him. He knew the young men well and let nine soldiers go to the nearest town to have a holiday. But night fell and none came back to the camp. He was worried about it and stood at the gate. It was five to twelve when Mr. Hunt decided to go to the town and see what was happening with the young men. He started the car quickly and set off. At that moment the nine soldiers came back. It seemed they were all drunk. Of course they found the officer was angry.
“I’m sorry, sir,” said the first soldier. “I left the town on time. But something was wrong with my bus on my way here. I had to buy a horse and made it run fast. Bad luck! It died and I had to run back.”
And the other seven soldiers said they were late for the same reasons. It was the last soldier’s turn. He said, “I’m sorry, sir. I got on a bus on time, but…”
Having heard this, the officer became even angrier and stopped him at once. He called out, “If you say something was wrong with your bus, I’ll punish you at once!”

A young man applied for a job as a farmhand. When the farmer asked for his qualifications(资历), he said, “I can sleep when the wind blows.”
This puzzled the farmer. But he liked the young man, and hired him.
A few days later, the farmer and his wife were awakened in the night by a violent storm. They quickly began to check things out to see if all was safe from damage. They found that the doors of the farmhouse had been safely fastened, and a lot of wood had been set next to the fireplace.
The young man slept soundly.
The farmer and his wife then looked at their property (财产) carefully. They found that the farm tools had been placed in the storage room, safe from the bad weather. The tractor had been moved into the garage. The barn was properly locked. Even the animals were calm. All was well.
The farmer then understood the meaning of the young man’s words, “I can sleep when the wind blows.”
The farmhand did his work loyally. When the sky was clear, he had prepared for the storm in case it broke. So when the wind blew, there was no need for him to be afraid. He could sleep in peace. The underlined word “fastened” in Para. 3 can be replaced by ______.
| A．closed | B．damaged | C．taken | D．moved |

He was the baby with no name. Found and taken from the north Atlantic 6 days after the sinking of the Titanic in 1912, his tiny body so moved the salvage (救援) workers that they called him “our baby.” In their home port of Halifax, Nova Scotia, people collected money for a headstone in front of the baby's grave (墓), carved with the words: “To the memory of an unknown child.” He has rested there ever since.
But history has a way of uncovering its secrets. On Nov. 5, this year, three members of a family from Finland arrived at Halifax and laid fresh flowers at the grave. “This is our baby,” says Magda Schleifer, 68, a banker. She grew up hearing stories about a great-aunt named Maria Panula, 42, who had sailed on the Titanic for America to be reunited with her husband. According to the information Mrs. Schleifer had gathered, Panula gave up her seat on a lifeboat to search for her five children -- including a 13-month-old boy named Eino from whom she had become separated during the final minutes of the crossing. "We thought they were all lost in the sea," says Schleifer.
Now, using teeth and bone pieces taken from the baby's grave, scientists have compared the DNA from the Unknown Child with those collected from members of five families who lost relatives on the Titanic and never recovered the bodies. The result of the test points only to one possible person: young Eino. Now, the family sees no need for a new grave. "He belongs to the people of Halifax," says Schleifer, "They've taken care of him for 90 years."
Adapted from People, November 25, 2002What is probably the boy's last name?

The gray-haired lady can’t wait to leave the building to search for her dad. Unless watched, she will walk in the streets in an effort to find her father, who died 30 years ago.
Not all cases of Alzheimer’s disease look like this, but Alzheimer’s is a serious disease that is said to be the fourth or fifth leading cause of death for people over age 75. It is said that about three percent of the U.S. population over age 65 have Alzheimer’s. In the early stages, people may exhibit short-term memory loss. Some may experience changes in personality, easy to be angry. As the disease progresses, patients might lose the ability to move and may be unable to speak or move at all. This progressive disease generally lasts 8 to 10 years before death occurs.
While no one is certain what causes these changes in the brain’s nerve fibers （神经纤维）, their effect is certain. Alzheimer’s destroys not only the patients, but also spouses（配偶）, friends and families.
What should you do if you notice progressive memory loss in yourself or a loved one? Have the person examined by a doctor who is a specialist in the treatment of Alzheimer’s disease. Though many reasons other than Alzheimer’s disease may cause memory loss, its early diagnosis（诊断）and treatment may delay some of the most serious effects.
What feeling will you likely experience if a loved one suffers from Alzheimer’s disease? A person will often go through the various stages of sadness, shock, anger, and so on. If the spouse develops the disease, you may experience hurt and disappointment when he or she doesn’t remember you are married.
Life for the Alzheimer’s patients and their loved ones will never be the same as the disease progresses, bringing a deep sorrow, loss and even anger towards God. No matter what feelings are present, facing them honestly will serve one better than burying them.What can be inferred from the passage about the gray-haired day?
| A．She has been living with her father. |
| B．She was sad about the death of her father. |
| C．She can’t search for her father without being watched. |
| D．She suffers from Alzheimer’s disease. |

Memory loss occurs ________.
| A．from Alzheimer’s disease and nothing else |
| B．from sadness, shock, anger, and so on |
| C．for a number of reasons |
| D．with changes in personality |
From the passage we know that .

| B．it is still unknown what causes the changes in the brain’s nerve fibers |
| C．nerve fibers in the brain will cause Alzheimer’s disease |
| D．when one suffers from Alzheimer’s disease, he will be buried |
