Since 2013, Torobo, a robotic arm designed to test the limits of artificial intelligence, has had one ambition—to be admitted to the University of Tokyo. However, it has repeatedly failed. This year was no exception.

    In early November Torobo took an exam to prepare for an all-important standardized test. While Torobo's total score of 525 out of 950 was 14 points higher than in 2015，its standard score of 57.1% was slightly lower, because human students did better in the 2016 test.

    Though the score，which is higher than the national average, is enough to get the robot admitted to many other famous Japanese universities,
it falls short of the minimum required for the University of Tokyo.

    A closer analysis of the results showed that Torobo's newly programmed ability to solve complex physics problems helped increase its
year-over-year physics score from 46. 5% to 59%. The robot also dug deep into its database of information from textbooks and websites to obtain
an impressive 66.3% in world history. The average 60% scores acquired in the two math sections, were not too shabby either.

    But，while Torobo is able to handle knowledge-based questions and ones involving complex mathematical calculations, it has a hard time thinking independently. As a result, the robot is unable to fully understand multiple sentences and phrases to arrive at the logical conclusions required in the English language tests. This weakness was reflected in the weak oral and writing scores, which came in at 36.2% and 50.5%, respectively.

    Fortunately, after four tiring years, the robot's creators have decided to free Torobo from its annual test-taking suffering, the research team will instead focus on improving the robot's ability to pick out specific answers from massive sets of data—a skill that led to its excellent history scores. They believe the expertise(专业技术）will  help Torobo succeed as an industrial robot.

    Sometimes it can be easy to become too satisfied when it comes to living sustainably. We may all have recycling bins in our kitchens, but here are some ways you can live more sustainably.

    ⒈Put an end to plastic water bottles and one-off coffee cups

    The only way this is going to work is that if you have reusable options you really love, invest in a great water bottle. This is an advance payment, but it will save you money in the long run. A 750ml bottle of Evian costs 90p in Tesco, meaning if you buy one every two days you could save £10 within three weeks by filling up a reusable bottle at home.

    ⒉_______________________________________

    The high street is problematic on so many different levels. Not only are you buying items with questionable supply chains, but the carbon footprint of each product is shocking as well. Online shopping is even worse, with overpackaging for each item and the emissions from delivery trucks. The answer is to stick to reach-me-down or previously owned items as much as possible. Not only will this save you money, but there's also a sense of satisfaction in finding a hidden treasure from the flea market where you find outstanding bargains or something used, which you simply can't get from shopping in Wal-Mart or on Amazon.

    ⒊Think hard about your transportation

    Even if your car is supposedly a low-emissions model, it's still going to be a huge contribution to your carbon footprint. There are times when getting in a car can't be avoided, but if you can substitute just one flight a year with a train, one car journey a week with a bus, and one bus a month with a bike ride, you'll find that making more mindful transport decisions can easily make your day-to-day life more environmentally friendly with little effort.

    ⒋Try to buy local, seasonal produce

    You may think buying strawberries in December or courgettes in spring is no big deal, but the chemicals and fuel used to artificially copy the right environment for them to grow create harmful gas emissions. Similarly, the environmental impact of transporting produce from another country is huge. Buying from local farmers also means you can often ignore the huge amounts of packaging the supermarkets use.

    A fresh and gentle wind on your face, soft sand under your feet and blue waters as far as the eye can see. Is there any other Olympic sport that is played in such pleasant conditions as beach volleyball?

    "I've gone to a lot of beautiful places, and met a lot of beautiful people. That wouldn't have happened if I had been playing another sport," said Randy Stoklos, America's most famous beach volleyball player.

    The sport began as a four-a-side game on beaches in Southern California in the 1920s.The first recorded two-man game took place there in 1930, and the first tournament was held in Los Angeles 18 years later. The winners were awarded a case of Pepsi. In the 1950s, women started playing and the sport soon spread to Europe and South America. Yet at that time, beach volleyball was more an entertainment show than a sport, with beauty contests included. The Association of Volleyball Professionals was founded in 1983 and beach volleyball developed into a fast, athletic sport. Its world-wide popularity won beach volleyball a place at the 1996 Olympics in Atalanta, where 24 male teams and 16 female teams took part. At present, the US and Brazil are the best in the world at beach volleyball.

    The game came to China in the early 1990s and there have been national tournaments since 1994. It became an official event at the Eighth National Games in 1997.China's You Wenhui and Wang Lu finished ninth in the women's beach volleyball world championships in Brazil.

    Self-driving cars have been backed by the hope that they will save lives by getting involved in fewer crashes with fewer injuries and deaths than human-driven cars. But so far, most comparisons between human drivers and automated vehicles have been unfair.

    Crash statistics for human-driven cars are gathered from all sorts of driving situations, and on all types of roads. However, most of the data on self-driving cars' safety have been recorded often in good weather and on highways, where the most important tasks are staying in the car's own lane and not getting too close to the vehicle ahead. Automated cars are good at those tasks, but so are humans.

    It is true that self-driving cars don't get tired, angry, frustrated or drunk. But neither can they yet react to uncertain situations with the same skill or anticipation of an attentive human driver. Nor do they possess the foresight to avoid potential perils. They largely drive from moment to moment, rather than think ahead to possible events literally down the road.

    To a self-driving car, a bus full of people might appear quite similar to an uninhabited corn field. Indeed, deciding what action to take in an emergency is difficult for humans, but drivers have sacrificed themselves for the greater good of others. An automated system's limited understanding of the world means it will almost never evaluate (评估) a situation the same way a human would. And machines can't be programmed in advance to handle every imaginable set of events.

    Some people may argue that the promise of simply reducing the number of injuries and deaths is enough to support driverless cars. But experience from aviation (航空) shows that as new automated systems are introduced, there is often an increase in the rate of disasters.

    Therefore comparisons between humans and automated vehicles have to be performed carefully. To fairly evaluate driverless cars on how well they fulfill their promise of improved safety, it's important to ensure the data being presented actually provide a true comparison. After all, choosing to replace humans with automation has more effects than simply a one-for-one exchange.

    3D printing is a recent technological development that has started making its way into the marketplace. It is a way of making 3D objects from computer models. 3D printing works by adding together layers of material. This pattern is repeated until the layers form a shape for almost any purpose. The almost unlimited possibility of 3D printing is quickly leading to a revolution in how things are made and produced. As with most technology, 3D printing may help to create things that could benefit humans. However, it could also be used to create things that could harm other people.

    One of the promising aspects (方面) of 3D printing is that it may help doctors treat patients in need. Currently 3D printing is being used to create prostheses (假体) that helps replace missing noses and eyeballs, thus greatly cutting down on the usual wait time for a new prostheses. Dentists are also using 3D printers to create custom toothbrushes for patients' teeth. The toothbrush fits a person's teeth well, which means that they get a much cleaner mouth than with regular toothbrushes. Many scientists see the potential for 3D printing to create replacement organs for people who need organ transplants. This would save lives as it remove the need for such patients to wait for an organ donation (捐献).

    Although many people believe 3D printing is a positive technology that could help humans, it may also have the opposite effect. There is a recent controversy (争议) about the ability of 3D printing to produce arms such as guns. Recently, one organization announced the plans to produce a 3D plastic gun. Anyone with the proper technology and with the determination to make a gun could potentially do so. Will the future of 3D printing provide hope or danger to humans?
