The Brown Bear
My wife Laura and I were on the beach, with three of our children, taking pictures of shore birds near our home in Alaska when we spotted a bear. The bear was thin and small, moving aimlessly.
Just a few minutes later, I heard my daughter shouting, “Dad! The bear is right behind us!” An aggressive bear would usually rush forward to frighten away its enemy but would suddenly stop at the last minute. This one was silent and its ears pinned back---- the sign of an animal that is going in for the kill. And it was a cold April day. The bear behaved abnormally, probably because of hunger.
I held my camera tripod (三脚架) in both hands to form a barrier as the bear rushed into me. Its huge head was level with my chest and shoulders, and the tripod stuck across its mouth. It bit down and I found myself supporting its weight. I knew I would not be able to hold it for long.
Even so, this was a fight I had to win: I was all that stood between the bear and my family, who would stand little chance of running faster than a brown bear.
The bear hit at the camera, cutting it off the tripod. I raised my left arm to protect my face; the beast held tightly on the tripod and pressed it into my side. My arm could not move, and I sensed that my bones were going to break. www..com
Drawing back my free hand, I struck the bear as hard as I could for five to six times. The bear opened its mouth and I grasped its fur, trying to push it away. I was actually wrestling (扭打) with the bear at this point. Then, as suddenly as it had begun, the fight ended. The bear moved back toward the forest, before returning for another attack----- The first time I felt panic.
Apparently satisfied that we caused no further threat, the bear moved off, destroying a fence as it went. My arm was injured, but the outcome for us could hardly have been better. I’m proud that my family remained clear-headed when panic could have led to a very different outcome.The brown bear approached the family in order to _________.

Robots that can chat，find misplaced glasses，draw aeroplanes and play with your children are attracting thousands of visitors during an expo in Tokyo as Japan adapts to changes in society．
Robots，such as the sound．sensitive Chapit，answer simple questions and even joke with people to help them fight loneliness and stay alert in old age．
Japan has one of the world’s fastest-ageing societies and the government predicts that by 2050 the proportion of people over 65 will reach 40 percent．”Many older people in Japan live alone and have no one to talk to，”said Kazuya Kitamura representative of the expo organizer．“Communication robots accompany people and don’t mind listening to the same stories over and over again．”
Matsumoto’s“Personal Mobility Robot，”equipped with four cameras and a sensor to recognize the user's centre of gravity, is designed to help elderly move around without pressing buttons．using joysticks(操纵杆)or rotating wheels as in traditional wheelchairs．
The robot can also help find misplaced glasses by identifying them with a sensor．
Other robots，such as the award-winning“DiGRO”can support busy parents who have little time to play with their children．The robot can use the Internet to find a simple image and then draw pictures，keeping children company while parents work．
While Chapit，a relatively simple robot，managed to attract a corporate partner many researchers，such as Kiyoshi Matsumoto，a professor at the University of Tokyo，struggle to attract sponsors for more expensive projects．
“We have developed a robot that can assist many people，but we still haven’t found a sponsor,”said Matsumoto，who added that the cost of the machine，if mass-produced，would be comparable to that of a car．”In the current economic environment there are few companies willing to invest in such a costly project，”he said．It can be inferred from the text that_______．
| A．many children lack love from parents |
| B．robots helpful to the old will be in great demand |
| C．robots are the most useful to children |
| D．robots do better than people in healthcare |
It is difficult to find sponsors for robots because______.
| A．Japan is suffering economy depression |
| B．the robots are of poor design |
| C．the production of robots costs a lot |
| D．the future market is worrying |
What is the author’s attitude towards the robots referred to?
| A．Unsatisfied． | B．Doubtful． |
| C．Favorable． | D．Regretful． |
As I grew older, my dad and I grew further apart. We always had totally different opinions. He thought that college was a waste of time, but for me it was important to finish college. He wanted me to work my way to the top as he had done in his field, but I wanted a different life. There was a time when we did not talk with each other.
A few months ago, I heard that my 84-year-old dad was in poor health. When he called and asked whether I could move from Colorado back to Tennessee to help him, I knew he was seriously ill. I am his only child and so it was time to meet my father's requirement.
Two weeks after moving back，we bought a boat and started fishing again. Fishing was one of the few things that we did while I was young and that we both enjoyed. It is strange but true that as we are fishing we are able to put things that have kept us apart for so many years behind us. We are able to talk about things that we have never talked about before. Fishing has been healing the old wounds that have kept us apart.
It is not important how many fish we catch. It is about enjoying the relationship that we have not had for years. I' m 62 and he is 84. When we are on the lake fishing, it is like enjoying life. It is far better to find a way to put the unhappy past behind. I am so lucky to spend the happy time with my father in his last years. Now my heart is filled with love.

Millions of sports lovers are still thinking about one thing----the Winter Olympics in Sochi Russia. Close to 2900 men and women competed in the 2014 Winter Games about a month ago.
The Olympics brought a lot of attention to Sochi, a city on the Black Sea, which is a popular area for vacation travelers. The area is known for its mild winters.
At least $50 billion was spent on the 2014 Winter Games, making it the costliest Olympics in history. Seven billion dollars was spent on the 2010 Winter Games in Vancouver, Canada. Olympic officials chose Sochi to host the 2014 games almost seven years ago. At that time, Russian President Vladimir Putin said the games would cost about $13 billion. Yet the actual expenses exceeded his estimate. So where did all the money go?
Some observers say the high cost is partly the result of security measures. Brian Jenkins, a terrorism expert from the RAND Corporation, gave the following explanation. There were anywhere between 70,000 and 100, 000 policemen and military troops deployed around the city.
The main threat came from separatist and Islamist groups from the North Caucasus, especially from Chechnya and Dagestan. One group claimed responsibility for two suicide bombings in Volgograd last December. The attacks killed more than 30 people. The city is only about 600 kilometers away from Sochi.
Bruce Hoffman is a terrorism expert from Georgetown University in Washington DC. He says the increased security made Sochi a difficult target for terrorists.
It is thought that the terrorists' intention was to make life difficult for the Russians and to create some sort of incident that would take away the enjoyment.
The last Olympians from around the world on Russian soil were in 1980. That was a year after Soviet troops invaded Afghanistan. More than sixty countries didn’t take part in the Moscow Summer Games to show their anger.According to the passage, why did the Sochi Winter Olympics cost so much?
| A．Because it was held at an area popular for vacation travelers. |
| B．Because the Russian government wanted to make it the best ever held. |
| C．Because security measures at Sochi were stricter than before. |
| D．Because the original plan was made 7 years before. |
It can be known from the passage that Bruce Hoffman was .
| A．a terrorism expert from the USA |
| B．the writer who wrote this article |
| C．an athlete who competed in Sochi |
| D．a terrorism expert from RAND Corporation |
Which of the following is false?
| A．Sochi Olympics cost about 4 times as estimated. |
| B．Next winter Olympics will be held in Vancouver. |
| C．Many countries refused to attend the 1980 Olympics. |
| D．Security is often a problem in international sport games. |
The terrorists might have attacked Sochi Olympics because .
| A．they wanted to make trouble for the Russians |
| B．they thought Russia shouldn't spend so much on sport |
| C．they thought Putin was not a nice president |
| D．they were not interested in winter sports |
Humans aren’t the only ones getting a buzz from coffee．Caffeine can improve memory among honeybees and lead to better pollination(授粉)．According to a recent study published in the journal Science．
The study was conducted by a team of researchers at Newcastle University in the United Kingdom．They found that the nectar(花蜜)of some flowers，such as those from grapefruit and lemon plants，as well as certain coffee flowers，contains low doses of caffeine．To get bees to feed on these flowers，the team trained the insects to associate food with the smell of the flowers．They also trained another group of bees to feed on nectar from flowers that were sweetened with a sugar, but did not contain caffeine．After 24 hours，the bees trained on caffeinated flowers returned to these plants three times as often as those trained on the sweetened flowers returned to the uncaffeinated plants．
Professor Geraldine Wright led the researchers．“Remembering floral traits(花部特征)is difficult for bees to perform at a fast pace as they fly from flower to flower and we found that caffeine helps the bee remember where the flowers are，”Wright said in a statement．
Improved memory led to the better pollination．That’s because once bees sip the caffeine nectar, they continue to look for more coffee plants to pollinate．This also suggests that caffeine plays a role in improving the bees’ability to search for food．
Researchers found that caffeine’s effect on the bee brain is similar to its effect on mammals．“The change is similar to that produced by caffeine in neurons(神经元)associated with learning and memory in the rat brain，”Wright said．
Bee populations have declining since 2007．The dramatic drop in the insects’numbers has serious effects for ecosystems and the farming industry．Bees are needed in the reproduction of crops and spreading wild flower species．Understanding what keeps bees buzzing could help to make sure that the insects are able to remember and pollinate their favorite flowers．Which of the following is mentioned in the passage?
| A．Caffeine has no effect on the rat brain． |
| B． Bee population has been increasing． |
| C．The nectar of lemon plants contains caffeine． |
| D．Bees dislike nectar from sweetened flowers． |
After reading the passage，John，who works in the farming industry, will probably feel ____________.
| A．annoyed | B．angry | C．nervous | D．excited |
Which of the following relationship is correct according to the passage?
| A．improved memory—caffeine nectar—better pollination |
| B．caffeine nectar—improved memory—better pollination |
| C．improved memory—better pollination—caffeine nectar |
| D．caffeine nectar—better pollination—improved memory |
What section of a newspaper may this passage be taken from?
| A．Science | B．Education |

In the Caucasus (高加索) region of Russia, nearly 50 out of every 100,000 people live to celebrate their 100th birthday, and many don’t stop at 100! By comparison, in America only 3 people in 100,000 reach 100. But these Russian old people aren’t alone. The Pakistanis, who live high in the Himalaya Mountains, and the Ecuadorans (厄瓜多尔人) of the Andes Mountains seem to share the secret of long life, too.
These people remain healthy in body and spirit despite the passage of time. While many older persons in industrial societies become weak and ill in their 60s and 70s, some Caucasians aged 100 to 140, work in the fields beside their great-great-grandchildren. Even the idea of aging is foreign to them. When asked “at what age does youth end?” most of these old people had no answer. Several replied, “Well, perhaps at age 80.”
What accounts for (解释) this ability to survive to such old age, and to survive so well? First of all, hard physical work is a way of life for all of these long-living people. They begin their long days of physical labor as children and never seem to stop. For example, Mr. Rustam Mamedov is 142 years of age. His wife is 116 years old. They have been married for 90 years. Mr. Mamedov has no intention of retiring from his life as a farmer. “Why? What else would I do?” he asks. All these people get healthful rewards from the environment in which they work. They all come from mountainous regions. They live and work at elevations (海拔) of 1,660 to 1,000 meters above sea level. The air has less oxygen and is pollution-free. This reduced-oxygen environment makes the heart and blood vessel (血管) system stronger.
Another factor that may contribute to the good health of these people is their isolation. To a great extent (程度), they are separated from the pressures and worries of industrial society. Inherited (遗传) factors also play some role. Most of the longest-living people had parents and grandparents who also reached very old ages. Good family genes may, therefore, be one factor in living longer.
| A．become weak and hopeless |
| B．benefit from physical work |
| C．are too old to work in the fields |
| D．are still working in the fields |
| A．Retiring from their lives as farmers. |
| B．Having been married for 90 years. |
| C．Hard physical work. |
| D．Having no intentions. |
| A．Clean mountain air. | B．Daily hard work. |
| C．Good genes | D．Stress and pressure. |
| A．the state of being separated | B．pressure |
| C．lack of physical labour | D．worry |
| A．Russian people live longer than Americans |
| B．People in the city live longer than those in the country |
| C．The reason why mountainous people live longer |
| D．Pressures and worries contribute to long life |
