Animal experts in Croatia say a bear has learned how to trick people to let him in by knocking at the door.
They believe the 220- kilogram brown bear probably learned the trick while nudging (轻推) a door to get it to open.
Experts have a guess that the nudging was mistaken by the owners for knocking and that the bear, pleased by the result, repeated the trick.
The Loknar family from Gerovo in western Croatia said the bear had knocked at their door three times and they were now refusing to answer the door.
‘‘We jumped out of the window as he came in through the door and went into the kitchen to take some food for the first time.” Mum Nevenka Loknar told a reporter from a local newspaper. “I opened the door and saw him standing there and I didn’t believe my eyes at first, then I ran for it as he walked in as if it was the most normal- thing in the world.”
Bears are a common thing in the woods around here, but no one has ever heard of a bear that knocks at the door.
Mum Nevenka Loknar said, “The bear is so intelligent. It’s incredible. We’ve tried to put up lots of obstacles to stop him coming in, like a wire fence but he still gets through. I wouldn’t be surprised if he knew how to use wire cutters.”According to experts in Croatia, how did the bear learn the trick?
| A．By knocking at the door several times. | B．By accident. |
| C．By learning from the owner of a family. | D．By imitation. |
What does the underlined word “it” in paragraph 5 refers to?
| A．Eating at the kitchen. | B．Knocking at the door. |
| C．Walking into the house. | D．Answering the door. |
It is ________ in Gerovo that a bear knocks at the door.
| A．unusual | B．a troubling problem | C．common | D．an exciting experience |
Mum Nevenka Loknar was surprised that the bear ________.
| A．didn’t attack her family |
| B．knew how to use wire cutters |
| C．jumped across her wire fence three times |
| D．was clever at getting through the obstacles |
Poor Oral Health Leads to Social and Emotional Problems
A new report says nearly four-billion people have major tooth decay, or cavities. That number represents more than half of the world's population. Health officials are warning that failure to repair cavities can lead to social and emotional problems.
Wagner Marcenes is with the Institute of Dentistry at Queen Mary, University of London. He led a team of researchers as part of the Global Burden of Disease 2010 study. About 500 researchers attempt to collect and examine studies about all major diseases. They used the information to estimate rates of the infection.
The report says untreated tooth decay is the most common of all 291 major diseases and injuries. Professor Marcenes says cavities or holes in permanent teeth are also known as caries.
"Caries is a chronic disease that shares the same risk factors as cancer, cardiovascular disease. What we're having now is an increase in disease from highly developed countries happening in sub-Saharan Africa and probably it will be in other areas of Africa, too."
He says an increase in tooth decay in Africa could be a result of developing countries becoming more like Western nations.
"It is likely to be related to a change in diet. Our industrialized diet leads to chronic disease, which includes caries. And that may be the main explanation."
Western diets are rich in sugar, a leading cause of health problems in the mouth. Wagner Marcenes says oral health problems can have a major effect on a person's quality of life. First, cavities make eating difficult. Second, people may change what they eat. They may eat softer foods that are not hard to chew. However, softer foods are often fattier foods.
But professor Marcenes says the biggest issue in tooth decay is both social and mental. He says the researchers found strong evidence that the mouth has a big influence on socialization. He says many people want to hide bad teeth. They smile less and communicate less.
Wagner Marcenes is calling for an "urgent, organized, social response" to the widespread lack of oral health. He believes in a natural method to fight tooth decay by having a healthier diet. He is also calling for the development of new and less costly dental materials and treatments.From the passage, we know that Wagner Marcenes ______.
| A．works as the leader of the Institute of Dentistry at Queen Mary, University of London. |
| B．and his researchers accumulate some studies to find out some ways to cure all major disease. |

It had been a difficult move. I’d left my family and friends in Indiana, the beloved state where I’d lived most of my life. My new home in Florida was thousands of miles away from anything I knew. It was hot—all the time. Jobs were hard to come by, but I was up for almost any challenge.
At last, I taught in a special school where students have severe learning and behavioral difficulties.
Another teacher and I had spent weeks teaching the children appropriate behavior for public outings. Unexpectedly, only a few students, including Kyle, had not earned the privilege of going. He was determined to make his disappointment known.
In the corridor(走廊) between classrooms, he began screaming, cursing, spitting, and swinging at anything within striking distance. Once his outburst died down, he did what he’d done when he was angry at all his other schools, at home, even once at a juvenile detention(拘留)center. He ran.
People watched in disbelief as Kyle dashed straight into the heavy morning traffic in front of the school.
I heard someone shout, “Call the police!”
But I ran after him.
Kyle was at least a foot taller than me. And he was fast. His older brothers were track stars at the nearby high school. But I could run long distances without tiring. I would at least be able to keep him in my sight and know he was alive.
After several blocks of running directly into oncoming traffic, Kyle slowed his pace.
He took a sharp left. Standing next to a trash bin, Kyle bent over with his hands on his knees. I must have looked ridiculous. But his was not a look of fear. I saw his body relax. He did not attempt to run again. Kyle stood still and watched me approach. I had no idea what I was going to say or do, but I kept walking closer.
He opened his mouth to speak when a police car pulled up, abruptly filling the space between Kyle and me. The school principal and an officer got out. They spoke calmly to Kyle, who willingly climbed into the back of the vehicle. I couldn’t hear what was said, but I didn’t take my eyes off Kyle’s face, even as they drove away.
I couldn’t help but feel that I had failed him, that I should have done or said more, that I should have fixed the situation.
I shared my feelings with a speech therapist who was familiar with Kyle’s history. “No one ever ran after him before, Rachel,” she said. “No one. They just let him go.”
Things changed the day he ran and I ran after him, even though I didn’t have the right words, even though I wasn’t able to save him from the mess he was in. It was the day I didn’t throw my hands in the air and decide he was too fast, a waste of time and effort , a lost cause. It was the day my mere presence was enough to make a profound difference.From the passage we know that _____.

Digital Trend: BOOKLESS LIBRARIES
What if you could fit all of a library’s collection in the palm of your hand? That’s part of the idea behind an upcoming bookless public library in San Antonio. Called Biblio Tech, the system will lend out e-readers loaded with 10,000 titles for two-to-three –week periods. But don't bother holding on to the device longer than that because it’s programmed to go dead.
Other libraries have tried similar programs: In 2002, the Santa Rosa Branch Library in Tucson, Arizona, launched a digital-only facility, and a bookless project was proposed last year in Newport Beach, California. Those digital-only projects folded—residents wanted their paperbacks—but Stanford University maintains a successful bookless engineering library with over 65,000 titles. Officials say digital libraries are a low-cost way to educate the masses and argue their rise is inevitable.
Still, some insist print isn’t doomed. A recent Wall Street Journal article notes that e-book purchases skew（倾斜）heavily toward the sort of “light entertainment” novels you can pick up at the grocery store. A survey from the Pew Research Center shows that about 90 percent of digital readers still crack open physical books.( After all, there are only four Twilight books. How hard is it to drag those around?)From the first paragraph, we can tell _____.
| A．you can always keep all of the books in your hands, |
| B．Biblio Tech will lend readers 10,000 books temporarily. |
| C．the books will not be stored in your device forever. |
| D．the bookless public library can be found in San Antonio now. |
The following statements are true except that _____.
| A．the Santa Rosa Branch Library lend out e-readers with 10,000 books. |
| B．the physical books are still popular despite those bookless projects. |
| C．Stanford University sets a successful example of bookless engineering. |
| D．some officials agree that digital libraries are educative and unavoidable. |
What is the meaning of the underlined word in paragraph 2?
| A．succeeded | B．opened | C．accepted | D．failed |
Some people insist that print will not disappear because _____.
| A．e-books are mainly sort of “light entertainment” novels. |
| B．most of the digital readers prefer books about physics. |
| C．a majority of e-reader users still choose to read paperbacks. |
| D．it is easy to take 4 Twilight books everywhere. |
Strange Baby-Naming Laws
Germany Parents are banned by law from using last names and the names of objects and products as first names. A child’s first name must clearly indicate his or her sex, and all names must be approved by the office of vital statistics in the area in which the child was born.
Iceland The country’s naming committee consults the National Register of Persons to determine if a name is acceptable. If parents want to go off-list, they must apply for approval and pay a fee, and the name must contain only letters in the Icelandic alphabet.
New Zealand The country’s Births, Deaths, and Marriages Registration Act of 1995 prohibits parents from choosing a name that “ might cause offense to a reasonable person; is unreasonably long; or is, includes, or resembles an official title or rank,” including, apparently, Adolf Hitler and Yeah Detroit—both names recently rejected.
Denmark If Danish parents prefer a moniker not on the list of 7,000 preapproved baby names, they must get permission from local church and government officials. Fifteen to 20 percent of the 1,100 reviewed names—including creative spellings of common names, last names as first names, and unusual names—are rejected each year.You can tell whether a baby is a girl or a boy according to the first name in _____.
| A．Denmark | B．New Zealand | C．Iceland | D．Germany |

| A．be approved by the office of vital statistics. |
| B．be accepted by the National Register of Persons. |
| C．contain only letters in the Roman alphabet. |
| D．be paid for some money. |
Which name is accepted in New Zealand?
| A．Bin Laden | B．Talula Does The Hula |
| C．Keenan Got Lucky | D．John Smith |
According to the passage, which of the following is true?
| A．Danish babies’ names should be on the list if parents can’t get the permission. |
| B．Each year about 150-200 reviewed names are rejected in Denmark. |
| C．Adolf Hitler is banned in Iceland. |
| D．Parents should pay a fee for babies’ names if the names are rejected. |
Our senses aren't just delivering a strict view of what’s going on in the world; they're affected by what’s going on in our heads. A new study finds that hungry people see food-related words more clearly than people who've just eaten.
Psychologists have known for decades that what's going on inside our head affects our senses. For example, poorer children think coins are larger than they are, and hungry people think pictures of food are brighter. Rémi Radel of University of Nice Sophia-Antipolis, France, wanted to investigate how this happens.
Does it happen right away as the brain receives signals from the eyes or a little later as the brain’s high-1evel thinking processes get involved. Radel recruited 42 students with a normal body mass index. On the day of his or her test, each student was told to arrive at the lab at noon after three or four hours of not eating. Then they were told there was a delay. Some were told to come back in 10 minutes; others were given an hour to get lunch first. So half the students were hungry when they did the experiment and the other half had just eaten.
For the experiment, the participant looked at a computer screen. One by one, 80 words flashed on the screen for about l/300th of a second each. They flashed at so small a size that the students could only consciously perceive. A quarter of the words were food-related. After each word, each person was asked how bright the word was and asked to choose which of two words they’d seen-a food-related word like cake or a neutral word like boat. Each word appeared too briefly for the participant to really read it.
Hungry people saw the food-related words as brighter and were better at identifying food- related words. Because the word appeared too quickly for them to be reliably seen, this means that the difference is in perception, not in thinking processes, Radel says. "This is something great to me. Humans can really perceive what they need or what they strive for. From the experiment, I know that our brain can really be at the disposal of our motives and needs. "Radel says. Why was there a delay on the day of the experiment?
| A．Because hungry people needed time to fill their stomach. |
| B．Because Radel wanted to create two groups of testers, hungry and non-hungry. |
| C．Because noon was not the right time for any experiment. |
| D．Because Radel needed time to select participants in terms of body mass index. |
What does the writer want to tell us?
| A．Human’s senses aren’t just delivering a strict view of what’s going on in the world. |
| B．What’s perceived by our senses affects our way of thinking. |
| C．Human brains can really be at the disposal of our motives and needs. |
| D．Thinking processes guarantee the normal functions of our senses. |
What can we infer from the passage?
| A．42 participants are too small a number for a serious investigation. |
| B．An experiment with hungry and non-hungry participants is not reliable. |
| C．Our thinking processes are independent of our senses. |
| D．Humans can perceive what they need without involving high-level thinking processes |
