    The argument that human-caused carbon emissions(排放) are merely a drop in the bucket compared to greenhouse gases generated by volcanoes has been making its way around the rumor mill for years. And while it seems to be reasonable, the science just doesn't back it up.

    According to the US Geological Survey (USGS), the world's volcanoes, both on land and undersea, generate about 200 million tons of carbon dioxide (CO2) annually, while our automotive and industrial activities cause some 24 billion tons of CO2 emissions every year worldwide. Despite the arguments to the contrary, the facts speak for themselves: Greenhouse gas emissions from volcanoes compose less than one percent of those generated by today's human activities.

    Another indication that human emissions surpass those of volcanoes is the fact that atmospheric CO2 levels as measured by sampling stations around the world, have gone up consistently year after year regardless of whether or not there have been major volcanic eruptions in specific years. "If it were true that individual volcanic eruptions dominated human emissions and were causing the rise in carbon dioxide concentrations, then these carbon dioxide records would be full of spikes —one for each eruption," says Coby Beck, a journalist writing for online environmental news. "Instead, such records show a smooth and regular trend."

    Furthermore, some scientists believe that volcanic eruptions, like that of Mt.St. Helens in 1980 and Mt. Pinatubo in 1991, actually lead to short-term global cooling, not warming, as sulfur dioxide (SO2), ash and other particles in the air and stratosphere(平流层) reflect some solar energy instead of letting it into Earth's atmosphere. SO2, which converts to sulfuric acid aerosol, when it hits the stratosphere, can linger there for as long as seven years and can exercise a cooling effect long after a volcanic eruption has taken place.

    Scientists tracking the effects of the major 1991 eruption of the Philippines' Mt. Pinatubo found that the overall effect of the blast was to cool the surface of the Earth globally by some 0.5 degrees Celsius a year later, even though rising human greenhouse gas emissions and an El Nino event caused some surface warming during the 1991-1993 study period.

    In an interesting twist on the issue, British researchers last year published an article in the peer reviewed scientific journal Nature showing how volcanic activity may be contributing to the melting of ice caps in Antarctica but not because of any emissions, natural or man-made. Instead, scientists Hugh Corr and David Vaughan of the British Antarctic Survey believe that volcanoes underneath Antarctica may be melting the continents ice sheets from below, just as warming air temperatures from human-induced emissions erode them from above.

(1)、According to Paragraph 1, some people argue that   .
A、their opinion is supported by science. B、volcanoes generate most of the greenhouse gases. C、human activities are to blame for greenhouse gases. D、carbon emissions produced by volcanoes are increasing.
(2)、What does the underlined word "spikes" in Paragraph 3 probably mean?
A、Sudden increases. B、Smooth trends. C、Stable regularities. D、Sharp declines.
(3)、What do the scientists mentioned in this passage believe about volcanic eruptions?
A、They brought about global warming. B、They actually partly cooled the surface of the Earth. C、They melted the ice sheets in Antarctic from above. D、They dominated human emissions in greenhouse effect.
(4)、The purpose of the passage is to      .
A、compare the results of the studies. B、contradict a view held by some people. C、present new findings for greenhouse phenomenon. D、report the effects of CO2, in greenhouse phenomenon.

                                                                               A Special Appointment

    Years ago I moved to Woodland Hills to take a job in a small hospital's emergency department. No one wanted to work on Christmas Eve, so the shift (轮班) went to me. I kissed my family goodbye and went off to spend the night in the hospital. It was a thankless job.

At 9 pm, the ambulance brought in a man in his 60s who was having a heart attack. His face was pale, and he was frightened. The whole night I did my best to save his life. Before I left in the morning to spend Christmas with my family, I stopped by to see how he was doing. It was still tough, but he had survived the night and was sleeping.

    The following year I got Christmas Eve duty again. At 9 pm sharp, the ward clerk told me there was a couple who wanted to speak with me. When I approached them, the man introduced himself as Mr. Lee and said, “You probably don't remember me, but last Christmas Eve you saved my life. Thank you for the year you gave me.” He and his wife hugged me, handed me a small gift, and left.

    The following year a new doctor had joined the group, but I wanted to see if Mr. and Mrs. Lee would return. This time, I volunteered for the shift. I kept an eye on the door. Once again, at exactly 9 pm, the Lees appeared, carrying a warmly wrapped bundle. It was their new grandchild. Mr.Lee, his family and I spent 13 Christmas Eves together. In the later years the staff all knew about the story and would work to give me time with him in the break room, where we spent a half-hour each Christmas Eve.

    The last year I saw him, he brought me a gift. I carefully opened the package and found a crystal (水晶) bell inside. It was engraved (镌刻) with a single word: Friendship. Now, my family, friends and I ring that bell every Christmas Eve at exactly 9 pm and offer our best wishes to the man who we won't forget.

    Are you a procrastinator(拖拉者)? It's a common problem. And it can be harmful, as previous research has shown that people who procrastinate have higher levels of stress and lower well-being, reported the Association for Psychological Science in the US. But a new study has found a way to deal with this problem: Be more connected to your future self.

    Psychologists think that each person believes that they are really two people: “Present Me” and “Future Me”. “People act as if they prefer their current selves' needs and desires to those of their future selves,” wrote psychologists Neil Lewis and Daphna Oyserman.

    Oyserman and Lewis decided to try to find a way to make “Present Me” imagine exactly how “Future Me” would feel the night before a big paper was due, though “Present Me” hadn't started yet. They made “Present Me” think about a far-off event as a number of days away, not months or years.

    Thinking about events in this way meant that something like a friend's wedding seemed 16.3 days sooner when considered in days rather than months and 11.4 months sooner when considered in months rather than years.

    The researchers also tried to find out whether people would take action sooner if they were told a certain event was happening in X days rather than years.  For example, participants imagined they had a newborn child, and that the child would need to go to college in either 18 years or 6,570 days. The researchers found those in the “days” condition planned to start saving four times sooner than those in the “years” condition.

    So if you think of your life in days instead of years, you may get things done quicker.

阅读短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

    I prefer Lynne Truss's phraseology: I am a grammar "sticker". And, like Truss—author of Eats, shoots & Leaves – I have a "zero tolerance" approach to grammar mistakes that make people look stupid.

    Now, Truss and I disagree on what it means to have "zero tolerance". She thinks that people who mix up basic grammar "deserve to be struck by lightning, hacked (砍) up on the spot and buried in an unmarked grave", while I just think they deserve to be passed over for a job—even if they are otherwise qualified for the position.

    Everyone who applies for a position at either of my companies, iFixit or Dozuki, takes a compulsory grammar test. If job hopefuls can't distinguish between "to" and "too", their applications go into the bin.

    Of course, we write for a living. iFixit.com is the world's largest online repair manual (指南), and Dozuki helps companies write their own technical documentation, like paperless work instructions and step-by-step user manuals. So, it makes sense that we've made a strong strike against grammar errors.

    But grammar is relevant for all companies. Yes, language is constantly changing, but that doesn't make grammar unimportant. Good grammar is credibility, especially on the Internet. And, for better or worse, people judge you if you can't tell the difference between "their" "there" and "they're".

    Good grammar makes good business sense—and not just when it comes to hiring writers. Writing isn't in the official job description of most people in our office. Still, we give our grammar test to everybody, including our salespeople, our operations staff, and our programmers.

    Grammar signifies more than just a person's ability to remember high school English. I've found that people who make fewer mistakes on a grammar test also make fewer mistakes when they are doing something completely unrelated to writing—like stocking shelves or labeling parts. It is the same with programmers. Applicants who don't think writing is important are likely to think lots of other things also aren't important.

    Mill 180 Park is truly a park for the 2lst century, designed to copy all of the great urban parks -Central Park in New York City, Hyde Park in London and Ueno Park in Tokyo. Through the use of computerized sound and some other modern systems, we've brought the outside in, surrounding our visitors with green space and a remarkable sense of the natural world.

    We spent a lot of time trying to learn why these parks are so beloved, what makes them work so well for their sponsors, and how they provide a place of rest for so many.

A wake up call for the senses

    These parks are beautiful. They provide much needed relief from the daily stress of city living in any particular moment. But with the good, every one of these parks suffer from the same shortcoming-they are not fit to live when the weather is bad. What this means is that our parks are only really available to us some of the time.

Change in the air

    Enjoying Mill 180 Park is not weather dependent. We used modern building techniques and technology to create a park that can be enjoyed in every season, during every type of weather.

Our focus

    While imagining the possibilities for Mill 180 Park, we focused our design process on five characteristics that were common in all of our favorite urban parks:

BEAUTY: Including natural and man-made qualities, delighting the senses of visitors.

GREENERY: Bringing nature to the city, with a variety of plants and green spaces.

MINGLING: Providing a place for people who wouldn't normally come into contact to meet and share experiences.

TRANQUILITY: Offering a place away from the noise, waste, and excitement of city life.

PROGRAMMING: Serving as a site for artistic, cultural, and amusement events that bring the community together.

    When you visit, you'll be aware on an intellectual level that you are not in an expansive outdoor space, but your senses will tell you otherwise.

Opening time and price

All months of the year.

Admission is free from Jan .I to Nov.30.

    Scientists at the University of Oxford have developed new artificial intelligence(AI) software to recognize and follow up the faces of chimpanzees(黑猩猩)in the wild. The new software will allow researchers and wildlife conservationists to significantly cut back on time spent analyzing videos, according to the new paper published in Science Advances.

    For species(物种)like chimpanzees which have complex social lives and live for many years, getting photos of their behavior taken from short-term field research can only tell us so much," says Dan Schofield, researcher and DPhil student at Oxford University's Private Models Lab, School of Anthropology. "By taking advantage of the power of machine learning to unlock large video files, it makes it possible to measure behavior over the long term."

    The computer model was trained using over 10 million images(影像):from Kyoto University s Primate Research Institute(PRI) video files of wild chimpanzees in Guinea, West Africa. The new software is the first to continuously track and recognize individual a wide range of poses, performing with high accuracy in difficult conditions such as low lighting and poor image quality.

    "Access to this large video file has allowed us to use deep neural networks to train models to a degree that was previously not possible," says Arsha Nagrad, co-auther of the study and DPhil student at the Department of Engineer Science, University of Oxford." Additionally, our new software differs from previous primate face recognition software in that it can be applied to videos with limited manual intervention(人工干预), saving hours of time."

    The technology can be potentially used to monitor species for conservation Although the present application focuses on chimpanzees, the AI software provided will be applied to other species, and help drive the adoption of AI systems to solve(解决)a range of problems in the wildlife sciences.
