    Since 50 years ago, scientists have been searching for ways to link the brain with computers. Brain Computer Interface (BCI) technology could help people with disabilities send commands to machines.

    Recently, two researchers, Jose Millan and Michelle 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.

(1)、What is BCI?
A、BCI is a technology that can link the human brain with computers. B、BCI is a technology that can help to update computer systems. C、BCI is a technology that can help the disabled to recover. D、BCI is a technology that can control a person's thoughts.
(2)、How did Tavella operate the wheelchair in the laboratory?
A、By controlling his muscles. B、By talking to the machine. C、By using his mind. D、By moving his hand.
(3)、Which of the following shows the path of the signals described in Paragraph 5?
A、scalp→computer→cap→wheelchair B、scalp→cap→computer→wheelchair C、computer→cap→scalp→wheelchair D、cap→computer→scalp→wheelchair
(4)、Which of the following would be the BEST title for the text?
A、Switzerland, the BCI Research Center B、New Findings about How the Human Brain Works C、Robotic Vehicles Could Help to Cure Brain Injuries D、BCI Could Mean More Freedom for the Disabled
举一反三

    I was on my school campus the other day, and there was an ice cream truck parked right in front of the main common areas of the school. I had never thought an ice cream truck would circle our campus and come for us, overgrown kids. I was intrigued and wanted to investigate(调查)further.

    I was quite surprised when the man in the truck called out,“ Free ice cream!”

    I questioned him just to make sure of his words, saying," I' m sorry, what did you say?"

    “Free ice cream. You have your choice of these four frozen treats: the rocket pop, the chocolate Eclair, the strawberry shortcake, or the drumstick.”

    After I was certain that the man was just giving away free ice cream, I talked with him for a while. He told me that his dream had always been to travel around giving away ice cream, and that's exactly what he did. And his passion was expressed through using up all his credit cards, sleeping in his truck, and living with his mother in a small flat, so he could continue to follow his dream during hard times .Now, he has sponsorships(赞助)from large companies such as Levi's to do what he loves, and he's gifted 125,000 of his truckload of ice cream treats!

    The man said he wanted to encourage people to do exactly what their hearts tell them to do with their lives. I kept asking him with respect," So your dream was just to drive around and give away ice cream? It seems like a very unusual goal."

    "Yes ,just meeting people and making them smile," he replied.

Dear Reader,

    Today I am going to ask you to support Wikipedia with a donation.

    Wikipedia is built differently from almost every other top 50 websites. We have a small number of paid staff,just twenty­three. Wikipedia content is free to use by anyone for any purpose. Our annual expenses are less than six million dollars. Wikipedia is run by the non­profit Wikimedia Foundation, which I founded in 2003.

    Wikipedia is driven by a global community of more than 150,000 volunteers — all devoted to sharing knowledge freely. Over almost eight years, these volunteers have contributed more than 11 million articles in 265 languages. More than 275 million people come to our website every month to access information,free of charge and free of advertising.

    But Wikipedia is more than a website. We share a common cause: Imagine a world in which every single person on the planet is given free access to the sum of all human knowledge. That's our commitment.

    Your donation helps us in several ways. Most importantly, you will help us cover the increasing cost of managing global traffic to one of the most popular websites on the Internet. Funds also help us improve the software that runs Wikipedia — making it easier to search, easier to read, and easier to write for. We are committed to increasing the free knowledge movement worldwide, by taking on new volunteers, and building strategic partnerships with institutions of culture and learning.

    Wikipedia is different. It's the largest encyclopedia (百科全书) in history, written by volunteers. Like a national park or a school, we don't believe advertising should have a place in Wikipedia. We want to keep it free and strong, but we need the support of thousands of people like you.

    Thank you,

Jimmy Wales

    Researchers continue to show the power behind our sense of smell. Recent studies have found, among other things, that the smell of foods like pizza can cause uncontrollable anger in drivers on roads.

    The review explains that smell is unique in its effects on the brain. According to Conrad King, the researcher who carried out the review, "more than any other senses, the sense of smell goes through the logical part of the brain and acts on the systems concerned with feelings. This is why the smell of baking bread can destroy the best intentions of a dieter."

    Smell, which dictates(决定) the unbelievable complexity of food tastes, has always been the least understood of our senses. Our noses are able to detect up to 10,000 distinct smells. Our ability to smell and taste this extremely large range of smells is controlled by something like 1,000 genes (基因), which make up an amazing 3% of the human genome. Researchers Richard Axel and Linda Buck were together awarded a Nobel Prize in 2004 for their ground-breaking research on the nature of this extraordinary sense. These two scientists were the first to describe the family of 1,000 olfactory (嗅觉) genes and to explain how our olfactory system works.

    According to one study in the research review, smelling fresh pizza or even the packaging of fast foods can be enough to make drivers feel impatient with other road users. They are then more likely to speed and experience uncontrollable anger on roads. The most reasonable explanation is that these can all make drivers feel hungry, and therefore desperate to satisfy their appetites.

    In contrast, the smells of peppermint and cinnamon were shown to improve concentration levels as well as reduce drivers' impatience. Similarly, the smells of lemon and coffee appeared to promote clear thinking and mental focus.

    However, the way genes regulate smell differs from person to person. A study by researchers in Israel has identified at least 50 olfactory genes which are switched on in some people and not in others. They believe this may explain why some of us love some smells and tastes while others hate them. The Israel researchers say their study shows that nearly every human being shows a different pattern of active and inactive smell-detecting receptors.
