1 . The history of microbiology begins with Dutch cloth maker named Antoni van Leeuwenhoek, a man of no formal scientific education. In the late 1600s. Leeuwenhoek, inspired by the magnifying lenses（放大镜）he used to examine cloth, built some of the first-microscopes. He developed technique to improve the quality of tiny, rounded lenses, some of which could magnify an object up to 270 times. After removing some plaque from between his teeth and examining it under a lens, Leeuwenhoek found tiny twisting creatures, which he called “animalcules”.
His observations, which he reported to the Royal Society of London, are among the first descriptions of microbes（微生物）. Leeuwenhoek discovered an entire universe invisible to the human eye. He found different microbes in samples of pond water, rain water, and human blood. He gave the first description of red blood cells, observed plant tissue, examined muscle, and investigated the life cycle of insects.
Nearly two hundred years later, Leeuwenhock’s discovery of microbes helped French chemist and biologist Louis Pasteur to develop his “theory of disease”. This concept suggested that disease originates from tiny organisms attacking and weakening the body. Pasteur’s theory later helped doctors to fight infectious diseases including anthrax, diphtheria, polio, smallpox, tetanus, and typhoid. All these breakthroughs were the result of Leeuwenhoek’s original work. Leeuwenhoek did not foresee this legacy.
In a 1716 letter, he described his contribution to science this way: “My work, which I’ve done for a long time, was not pursued in order to gain the praise I now enjoy, but chiefly from a strong desire for knowledge, which I notice resides in me more than in most other men. And therefore; whenever I found out anything remarkable, I have thought it my duty to put down my discovery on paper, so that the scientific community might be informed thereof.”

Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated (展示) a small robotic wheelchair directed by a person's thoughts.
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.
“Our brain has billions of nerve cells. These send signals through the spinal cord (脊髓) to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles.” Tavella says. “Our system allows disabled people to communicate with external world and also to control devices.”
The researchers designed a special cap for the user. This head cover picks up the signals from the scalp (头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.
Prof. Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair.”
He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.

3 . A man in Brisbane, Australia, survived a house fire early Wednesday morning because his pet parrot, named Eric, sounded the alarm.
Anton was asleep when his home caught fire just after 2:00 a.m., according to the Australian Broadcasting Corporation (ABC). Anton didn’t hear the smoke detector(探测器). Instead, he heard Eric calling his name repeatedly, ABC reported. “I heard a bang and Eric — my parrot— he started to yell so I woke up and I smelled a bit of smoke,” Anton told ABC. “I grabbed Eric, opened the door and looked to the back of the house and saw some flames,” he added. “And so I grabbed my bag and bolted downstairs.” Officials told ABC that Anton’s home did have a smoke detector, but it didn’t go off before Eric started calling “Anton! Anton!” Queensland Fire and Emergency Services Acting Inspector Cam Thomas told ABC that the firemen were able to contain the fire before it spread to other properties(财产).
According to ABC, there may be a crime(犯罪)and policemen are looking into what caused the fire. In the meantime, Anton is glad that he and Eric survived. “I’m in shock but I’m fine,” he told ABC. “Everything’s all right so long as I have myself and the bird.”

4 . An elm tree (榆树) was planted in the first half of the 20th century on a farm in Michigan, US.
In the 1950s, the family that owned the farm kept a bull chained to it. The bull walked around the tree. pulling a heavy iron chain, which made a grove (沟) in the tree about a meter off the ground. The groove deepened over the years, thought for whatever reason, it didn’t kill the tree.
After some years, the family sold the farm and took their bull with them. They cut the chain, leaving most of it hanging down from the tree. Eventually, bark (树皮) slowly covered the old chain.
Then one year later, disaster struck Michigan in the form of Dutch elm disease. It left a path of death across vast areas. All of the elms lining the road leading to the farm were infected and dies. Everyone figured that the old elm tree would be next. There was no way the tree could last, with its age and the chain hanging off its trunk.
The present owners considered pulling the chain out and chopping the tree up into firewood before it dies. But they simply couldn’t bring themselves to do it. It was as if the old tree had become a family friend, so they decided to let nature take its course. Amazingly, the tree didn’t die. Year after year, it grew stronger. Nobody could understand why it was the only elm still standing in the whole area.
Experts from Michigan University came to observe the tree later examining the scar left by the iron chain. The experts decided that it was actually the chain that saved the elm’s life. They reasoned that the tree must have absorbed so much iron from the chain that it became immune to Dutch elm disease.
It’s said that what doesn’t kill you will make you stronger. So if you’re ever in Michigan, look for that beautiful elm tree. Look for the wound made by the chain — it serves as a reminder that even with wounds, we can still have hope. Our wounds can give us the resources we need to cope and survive. They can truly make us strong.

5 . One advantage of the Internet is shopping conveniently online for clothes; one disadvantage of the Internet is also shopping conveniently online for clothes.
“Nothing fits,” said Lam Yuk Wong, a senior in electrical and computer engineering at Rice University. “Everyone says this. They order clothes and they don’t fit. People get very unhappy.”
Wong and her design partner, Xuaner "Cecilia" Zhang, are Team White Mirror, creators of what they call a "virtual (虚拟)fitting room". Their goal is simple and consumer-friendly: to let online clothing shoppers have a perfect fit and a perfect look when shopping every time. Both women are from China, Wong from Hong Kong and Zhang from Beijing. They both order most of their clothing online. They got the idea from their own experience as consumers and from listening to the complaints of friends and relatives. They say, ‘The color is wrong’ or ‘I got the right size but it still does not fit.’ We want to make it like you’re in the store trying on the clothes,” Zhang said.
Using a Kinect developed by Microsoft for use with its Xbox 360 video game player, Zhang scans Wong and turns her image into, in effect, a virtual model, keeping Wong's dimensions (尺寸), and even her skin and hair color
“We put the clothes on the shopper’s 3-D body models and show how they look when they are dressed,” Wong said. So far, Wong and Zhang have adapted the software to show dresses and shirts, and they are now working on shorts.
Asked if she thought men as well as women might be interested in using their virtual fitting room, Wong said, “I think their wives will care about this, so it will also be important to men.”
1. Why is shopping conveniently online for clothes a disadvantage?| A．Students may easily get addicted to it. |
| B．Clothes bought online may not fit |
| C．It attracts more online clothing shoppers. |
| D．It causes shoppers to waste too much money |
| A．scanning - trying on clothes - getting images |
| B．trying on clothes - getting models - scanning |
| C．scanning - getting models -trying on clothes |
| D．trying on clothes - getting images - scanning |
| A．It is perfectly developed | B．It will have its market share |
| C．It is limited to women shoppers. | D．It is like a kind of video game player |
6 . One day in March, seven years ago, during happy hours at a bar in my hometown of Fayetteville, Arkansas, I made a surprise announcement to my friends: I was going to shut down my law practice and attempt to travel around the globe in a year. What’s more, I would do it without taking any flights or making a single advance reservation (预定) of any kind. My announcement drew mixed reactions from my friends. Some offered support and encouragement, while others were more doubtful.
Once I had said the words, there was no turning back. I took months to shut down my law practice and get things in order. Once I set off on my adventure in December 2008, I found travelling without using planes was not easy. Trying to circle the globe in 16 months (it took me a bit longer than the initial 12 months I planned) made it even harder. Even so, travelling overland was the most amazing way to truly understand the immensity (浩瀚无际) of our wonderful planet.
I took three consecutive (连续) overnight buses to travel 3,000 km through Argentina, from Ushuaia to the capital Buenos Aires. I would look out of the windows for hours continuously at the completely plains, as if humans had never touched it.
It took seven consecutive days and nights on trains to get from Moscow to Beijing, each day spent staring out of the windows for hours as the Siberian plains swept by. Sometimes, I wouldn’t see a village or a human being for 10 hours. Later in my journey, it took 22 days on a cargo freighter (货船) to get from New Zealand through the Panama Canal and back to Philadelphia, to finish my round-the-world adventure.
It turned out that travelling with no reservations was far less difficult than I had imagined. Pulling into a city on a bus with a backpack, looking in a guidebook for a few suggestions of accommodations (住所), and then finding an empty room was never much of problem anywhere. It also kept me flexible (灵活) and open about all my travel plans, which is advice I give everyone who asks—plan for less than you think you should.

7 . If this isn’t true love then we don’t know what it is. High school sweethearts Leonard and Hazel Cherry passed away last Thursday just hours apart, a sweet ending to their 74-year together.
The couple were married in 1942 in Muldoon, Texas. Following their wedding ceremony at the start of World War II, Leonard enlisted in the Army Air Corps and became a B-24 bomber pilot. Luckily for the couple, he was never far from home as he was stationed at Carswell Army Air Corps Base in Fort Worth training others how to fly. Meanwhile, Hazel was a stay-at-home mom taking care of their only son, David. Once the war was over, Leonard worked as an auto body repairman in Fort Worth before opening an auto repair business in 1949, which the couple ran together for 31 years. The couple finally moved to Woodstock, Texas in 1980 to be close to their son and grandchildren.
In their final days, Leonard who was 95, was placed at the St. Catherine Center, a hospice (临终安养院) in Waco, Texas, while 93-year-old Hazel, who was in good health, had just moved into the village at Providence Park, a facility right next door to her husband’s.
Then on October 27, Leonard passed away just before 1 p.m. and his wife died just 10 hours later at 11 p.m.
“Every time I began to think about it, I began to smile because of how much they loved each other. In my mind my grandfather was waiting for her in heaven with open arms,” Craig Cherry told KWTX. “Even in his ninety-fifth year, he still, when he talked about her, had a sparkle (闪烁 的光) in his eye. A memorial service for them is scheduled for this Friday and I’m sure there won’t be a dry eye in the house.”

8 . Seventy years ago, in the city of Boston, there lived a small girl who had the naughty habit of running away. On a certain April morning, almost as soon as her mother finished buttoning her dress, Louisa May Alcott slid out of the house and up the street as fast as her feet could carry her.
It was a beautiful day, and she did not care so very much just where she went so long as she was having an adventure, all by herself. Suddenly she came upon some children who said they were going to a nice, tall ash heap to play. They asked her to join them. Louisa thought they were fine playmates, for when she grew hungry they shared some cold potatoes and bread crusts with her.
When she was tired of the ash heap she said goodbye to the children, thanked them for their kindness, and hop-skipped to the Common, where she must have wandered about for hours. All of a sudden, it began to grow dark. Then she wanted to get home. It frightened her when she could not find any street that looked natural. She was hungry and tired, too. She threw herself down on some door-steps to rest and to watch the lamplighter, for you must remember this was long before there was any gas or electricity in Boston. At this moment a big dog came along. He kissed her face and hands and then sat down beside her with a sober look in his eyes. Poor tired Louisa leaned against his neck and was fast asleep in no time. The dog kept very still. He did not want to wake her.
Pretty soon the town crier went by. He was ringing a bell and reading in a loud voice, from a paper in his hand, the description of a lost child. You see, Louisa's father and mother had missed her early in the forenoon and had looked for her in every place they could think of. Each hour they grew more worried, and at dusk they decided to hire this man to search the city.
When the runaway woke up and heard what the man was shouting— "Lost— Lost— A little girl, six years old, in a pink skirt, white hat, and new, green shoes" —she called out in the darkness, "Why— that's ME!" The town crier took Louisa by the hand and led her home, where you may be sure she was welcomed with joy.

9 . We all know that eating junk food can make us fat. However, a new study suggests that it can do more than that—it can also make us lazy.
In the study, researchers at the University of California, divided 32 female rats into two groups. The first group was fed a diet of healthy food such as corn and fish, while the second was given a diet of highly processed food rich in sugar, namely “junk food”.
Within three months, the rats in the second group were already much fatter than those on the healthy diet. And when researchers trained the rats to do simple tasks, they found even more differences between the two groups rather than weight.
During the task—pushing a lever (杠杆) to receive a reward of sugar water—the rats on the junk food diet were found to be less willing to move, and they took longer breaks between each push than the lean (瘦的) rats did.
“It is as if the rat is thinking ‘This is too much work’,” Aaron Blaisdell, leader of the study.
But what about the possibility that the fat rats were less passionate about getting sugar water because they were already eating lots of sugar in their daily diet? That’s why researchers repeated the tests by rewarding fat rats with plain water when they were extremely thirsty. However, the results came out just the same.
The experiment didn’t end there. After six months, the rats’ diets were switched, and the overweight rats were given a healthy diet for nine days. However, this change didn’t help reduce their weight or improve their ability to perform tasks, which means the effects of their junk food diet continued. “There’s no quick fix.” said Blaisdell.
For a long time, we’ve believed that people become fat because they are lazy. But this study has proven the opposite to be true as well, which indicates that laziness and obesity (肥胖) are a “vicious cycle (恶性循环)”.
So, if you constantly feel tired, lacking any urge to get up from your chair, it could be that you’ve been studying too hard. But you should also pay attention to your diet.

10 . A woman whose sports car was stolen with her dog in it put up notices all over the area that made it clear getting back her pet was more important than her car.
“Whoever did this can keep my car. Please let Benjerman come home,” the notice said.
It is not known whether the thief showed any pity, but almost 30 hours after the 1 p.m. theft Friday, Kimberly Atkins of Dover and Benjerman, a 12-year-old black retriever(猎犬), were reunited after police located them in Barrington.
“He’s hungry, he’s dirty, but he’s very happy to be home,” Atkins said.
The car was found at about 5 p.m. Saturday off Route 125 in a swampy area frequented by off-the-road cars and dirt bikes. However, the police couldn’t control Benjerman, and they had to call Atkins to come and get him.
Atkins said the thief cared for Benjerman a little by providing him with some dry cat food. She believed Benjerman ended up drinking some muddy water in the area.
She said they have been together for nearly 11 years after she took him hack from a society shelter in Dallas, Texas.
Before Benjerman was found, Atkins and several friends put up notices all over the city and in Somersworth. They also contacted animal shelters throughout southern New Hampshire and Massachusetts.
The notice stated there was a reward, and also that the dog needed medication. Any caller could remain anonymous(匿名的).
Atkins had parked the car outside a hardware store with the keys inside and gone in to rent a carpet cleaner.
“It was 10 minutes and I came out and my car was gone along with Benjerman in broad daylight,” Atkins said.
The car thief threw Atkins’ wallet and other personal items out of the car before escaping from the scene.
