根据短文理解,选择正确答案。

    Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all, you probably sing or whistle(吹口哨) when you are happy.

    Some scientists believe that birds do sing some of time just because they are happy. However, they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory.

    Do you know what a “territory” is? A territory is an area that an animal, usually the male, claims as its own. Only he and his family are welcome there. No other families of the same species(物种) are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. Probably this would be enough to frighten him away.

    If so, you have actually frightened the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time, especially at nesting(筑巢) season. So he is screaming all the time, whether he can see an outsider or not. This screaming is what we call a bird's song, and it is usually enough to keep an outsider away.

    Birds sing loudest in the spring when they are trying to attract a mate(配偶)and warn others not to enter the territory of theirs.

    You can see that birds have a language all their own. Most of it has something to do with attracting mates and setting up territories.

(1)、Some scientists believe that most of the time birds singing is actually ______.
A、an expression of happiness B、a way of warning C、an expression of anger D、a way of greeting
(2)、What is a bird's “territory”?
A、A place where families of other species are not accepted. B、A place where a bird may shout at the top of its voice. C、An area for which birds fight against each other. D、An area which a bird considers to be its own.
(3)、Why do birds keep on singing at nesting season?
A、Because they want to invite more friends. B、Because their singing helps keep outsiders away. C、Because they want to find outsiders around. D、Because their singing helps get rid of their fears.

    By now, you've probably been warned that a robot is coming for your job. But rather than repeat the warning, I've decided to throw down a challenge: man against machine.

    Start with the task we're doing right now: communicating in fluent human. We're sharing abstract ideas through words that we choose with an understanding of their slight difference and impact. We don't just speak in human; we speak as humans. A robot who says that science is fun is delivering a line (念一句话). A human who says that science is fun is telling you something important about being alive.

    Here's another inbuilt advantage we take for granted: as humans we are limited by design. We are bound in time: we die. We are bound in space: we can't be in more than one place at a time. That means when I speak to an audience, I am giving them something special. It's a custom-made, one-off, 100% robot-free delivery, from today's one-and-only Australian Chief Scientist.

    True, I now come in digital versions, through Twitter and Facebook and other platforms, but the availability of those tools hasn't stopped people from inviting me to speak in person. Digital Alan seems to increase the appetite for human Alan, just as Spotify (a digital music service) can increase the demand for a musician's live performances.

    Thanks to technology, many goods and services are cheaper, better and more accessible than ever before. We like our mass-produced bread, and our on-tap lectures and our automated FitBit advice. But automation hasn't killed the artisan bakery (面包店). Online courses haven't killed the booming, alongside their machine equivalents.

    Here's a third argument for the win. We humans have learned the habit of civilization. Let me explain this point by a story. A few years go, some researchers set out to study the way the people interact with robots. They sent out a small robot to patrol (巡逻) the local mall. That robot had a terrible time, and the villains of the story were children. They kicked him, bullied him, and smacked (掌击) him in the head.

    The point is not that the children were violent. The point is that the adults were not. They restrained whatever primitive impulse (冲动) they might have felt in childhood to smack something smaller and weaker in the head, because they had absorbed the habit of living together. We call it civilization. If we want artificial intelligence for the people, we'll need every bit of that civilizing instinct.

    Together, these points suggest to me that humanity has a powerful competitive edge. We can coexist with our increasingly capable machines and we can make space for the full breadth of human talents to flourish.

    This player is neither the answer to Bafana Bafana's goal-scoring problem, nor holds any hope of being in the national team for the World Cup. But Mmane Koko trains every morning and is now used to playing soccer. She said, 'Before I can do my domestic(家庭的) jobs, I go to train every morning. This helps me keep my body healthy. I started exercising after my doctor told me that exercising can keep my body healthy.'

    Mmane Koko, aged 66, said if she had been exposed to soccer at an earlier age, she would have become a top South African striker and could have stolen the limelight from Noko Matlou, who helped South Africa achieve its best ever result in the African women's soccer cup. She encourages young people to start playing sports early and to continue into their old age as it helps to lower blood pressure and prevent obesity(肥胖症).

    She added that because soccer is not only about exercising, but also helps one to put bread on the table, it could make a difference socially. She also says soccer is a business and that clubs these days pay generously. Therefore if the young take sports seriously, they can make a living out of it. But this can only happen if our government participate in developing sports and building stadiums for future generations.

    Exercise does us a lot of good as Mmane Koko says. We can live longer and feel better through exercise. It gives us energy surprisingly enough! Regular exercise reduces our risk of all kinds of disease. It can help us relieve stress and anxiety, increase our endurance(耐力) and sleep better. Exercise can contribute to our mental well-being and helps treat depression. So if you want to stay fit, keep on exercising to keep your body healthy.

    The world's first luxury space hotel, Aurora Station, was announced Thursday at the Space 2.0 Summit in San Jose, California. Developed by US-based space technology start-up Orion Span, the space station will host six people at a time, including two crew members, for 12-day trips of space travel. It plans to welcome its first guests in 2022.

    "Our goal is to make space accessible to all," Frank Bunger, CEO and founder of Orion Span, said in a statement." Upon launch, Aurora Station goes into service immediately, bringing travelers into space quickly and at a lower price point than ever seen before."

    While a$10 million trip is outside the budget of most people's two-week vacations, Orion Span claims to offer an authentic astronaut experience. "It has taken what was historically a 24-month training to prepare travelers to visit a space station and streamlined(精简)it to three months, at a fraction(小部分)of the cost," says Bunger. During their 12-day adventure, the super-rich travelers will fly at a height of 200 miles above the Earth's surface in Low Earth Orbit, where they will witness incredible views of the blue planet. The hotel will orbit Earth every 90 minutes, which means guests will see around 16 sunrises and sunsets every 24 hours.

    Activities on board include taking part in research experiments such as growing food while in orbit, which guests can take home for a super-smug souvenir, and soaring over their hometown. Guests can have-live-video chats with their less-fortunate loved ones back home via high-speed wireless Internet access and, upon(return to Earth will be greeted with a specially arranged hero's welcome. While enjoying the thrills of zero gravity, the travelers will be able to float freely through the hotel, taking in views of the northern and southern aurora from the station's windows.   Deposits are already being accepted for future stays on the space hotel.

    Overheated property markets in major cities have started to cool down after authorities took measures against speculative buying and a potential home market bubble. However, a long-term effort is needed to make the market stable and sustainable, analysts said.

    Last month, new home prices dropped in seven cities, compared with six in September, according to the National Bureau of Statistics, which monitors housing prices in 70 cities nationwide. In Shenzhen, where housing prices rocketed by more than 30 percent in the past several months, prices declined by 0.5 percent in October.

    “After first-tier cities and some key second-tier cities launched cooling measures, home prices have obviously become stable,”Liu Juanwei, NBS senior statistician, wrote in a note posted on the NBS website.

    Beijing, Tianjin, Shanghai, Xiamen and Zhengzhou began to see home prices switching from rising to dropping in the second half of October, with average prices down by between 0.1 percent and 0.4 percent compared with the first half of the month, he noted.

    Housing authorities in more than 20 cities have launched various measures against speculative buying to curb rapid home price growth, including setting stricter requirements for qualified buyers and limits on buying second and third homes.

    Yan Yuejin, an analyst with property research agency E-House China R&D Institute, said the residential property market is “digesting these policies and measures gradually, and it is likely for the market to have rational and stable prices in the near future.”

    Ma Junwei, an analyst with Deyi Realty in Shanghai, said it will require a long-term effort by regulators and local authorities to battle speculative buying while keeping supplies stable for buyers with solid demand, including those who plan to buy their first home or upgrade their housing.

    In Shanghai, real estate agents said that they have noticed that homebuyers have become more rational. “Buyers are starting to take their time and study their options. They will compare prices, designs and locations and bargain with sales representatives,”said Luo Dingjun, sales manager at Jinyu Property Marketing.“This was not the case two months ago, when they rushed to buy for fear that if they hesitated, prices would grow too fast and they would no longer be able to afford. ”

    In the famous fairy tale, Snow White eats the Queen's apple and falls victim to a curse(诅咒);in Shakespeare's novel, Romeo drinks the poison and dies; some ancient Chinese emperors took pellets(药丸)that contained mercury(水银), believing that it would make them immortal, but they died afterward.

    Poison(毒药) has long been an important ingredient in literature and history, and it seems to always be associated with evil, danger and death. But how much do you really know about poison?

    An exhibition, The Power of Poison, opened last month at the American Museum of Natural History in New York, intended to give the audience a more vivid understanding of poison.

    The museum tour starts in a rainforest setting, where you can see live examples of some of the most poisonous animals: caterpillars(毛毛虫), frogs and spiders. Golden poison frogs, for instance, aren't much bigger than a coin, but their skin is covered with a poison that can cut off the signaling power of your nerves, and a single frog has enough venom to kill 10 grown humans.

    "Poisons can be bad for some things," Michael Novacek, senior vice president of the museum, told NBC News. "Yet they can also be good for others."

    A poisonous chemical found in the yew tree is effective against cancer, which is what led to the invention of a cancer-fighting drug called Taxol.

    The benefits from natural poisons are not limited to just medicine. Believe it or not, many substances(物质)that we regularly ingest(摄入)-chili, coffee and chocolate-owe their special flavors or stimulating(提神的)effects to chemicals that plants make to poison insects.
