21、Last year scientists reported using a neural implant (神经植入物) in a man’s brain to restore his ability to communicate. The man has been partially paralyzed and unable to produce comprehensible speech since suffering a severe stroke. It is the latest advance in the exploding field of brain-computer interfaces (接口), or BCIs, which allow computers to read information out of a living brain.
Brain-computer interfaces are possible because of two facts. The first is that your brain contains hundreds of tiny maps. Each represents specific features of your physical feelings and intended actions. And crucially, the basic set of brain maps and their locations within the brain are very similar across individuals.
Thanks to their specialized functions and universal locations, brain maps are ideal entry points for BCI technologies. Picking up signals from a brain map is only the first step in making a useful BCI. Although the location of a brain map is the same across individuals, the details — what patterns of activity within the map mean — differ from person to person. In a sense, the unique features of your specific brain maps serve as a kind of encryption (加密), safeguarding your specific thoughts and feelings from would-be spies.
That brings us to the second fact that makes BCIs possible. Thanks to advances in machine learning, scientists have developed programs that can learn to recognize key patterns in a vast sea of numbers. They train these programs to decode (解码) brain signals by feeding them tons of examples. Researchers developing BCIs often create such examples by instructing an individual to think specific thoughts at specific times, creating a neural curriculum for the program to learn from.
While the universal features and locations of brain maps make them obvious entrances for BCIs, the unique features of your brain maps tend to protect them from spying eyes. In cases where BCIs have successfully read specific thoughts or intentions from a brain, it has been with the permission of the individual whose brain was being read. But there are surreptitious ways to train decoders on your brain without your knowledge. This can happen if your neural data falls into the hands of companies with detailed information about your activities.
Like all technologies, brain-computer interfaces are not necessarily good or bad. Yet while harvesting the benefits of BCIs, we need to ensure that we have the means to protect ourselves from corporations with every motive to take advantage of this technology for their financial gain.

22、 The electricity bill for an average family with 2 children is worth about 1 full salary per year, but the revolutionary EcoVolt could put 50% of that money back into your pocket.
In 2017, a revolutionary new product called EcoVolt hit the market. Initially it was separated from the general public, all because it offered the opportunity for average families to save up to 50% of their monthly energy costs. EcoVolt is a small, simple, affordable, and easy to use plug in unit that stops unnecessary power from entering the electrical cables and overloading the network, EcoVolt is the utility (公用事业) provider' s best-kept secret. They 've been trying to hide it from the everyday power consumer and even have banned the sale of it in retail shops —just to maximize their profit. However, thanks to the internet, the secret is now out, and everyday customers are now attaining the rewards of less power consumption overall, as well as less power used by household appliances. Your household appliances (家用电器) may last longer than previously. Basically, EcoVolt provides the opportunity for you to save between 30 and 50 percent on your energy bill. That's a phenomenal saving and leaves few questions as to why this has been hidden from consumers.
The benefits of EcoVolt are huge, and researchers are convinced this device could spell the end of unaffordable power bills that can cripple the average wage earner at the end of the month. Scientists initially spent many months trying to expose its efficiency, but those studies now prove that EcoVolt should be common in every household.
It's easy to connect, simply by plugging it into your wall, and it's suitable for both standard homes and apartments connected to a power grid (电网). It also has a counter which shows how you're making more efficient use of your energy, all the while allowing you to gain the rewards of a more everlasting household appliance lifecycle. In just 1-2 months, you've made your money back on your initial purchase.

23、 Researchers have succeeded in making an Al understand our subjective concept what makes faces attractive. The device(设备)showed this knowledge by its ability to create new photos on its own that were tailored to be found personally attractive to individuals(个人). The results can he used, for example, in modelling preferences and decision-making as well as potentially identifying unconscious attitudes.
Researchers at the University of Helsinki and University of Copenhagen tried to find out whether a computer would be able to identify the facial features we consider attractive and, based on this, create new images matching our criteria. The researchers used artificial intelligence to interpret brain signals and combined the resulting brain-computer interface with productive model of artificial faces. This enabled the computer to create facial images that appealed to individual preferences.
“In our previous studies, we designed models that could identify and control simple photo features, such as hair colour and emotion. However, people largely agree on who is blond and who smiles. Attractiveness is a more challenging subject of study, as it is associated with cultural and psychological factors that likely play unconscious roles in our individual preferences. Indeed, we often find it very hard to explain what it is exactly that makes something, or someone, beautiful”, says Senior Researcher and Docent Michiel Spape from the Department of Psychology and Logopedics, University of Helsinki.
“If this is possible in something that is as personal and subjective as attractiveness, we may also be able to look into other cognitive(认知的)functions such as opinions and decision-making. Potentially, we might make the device fit to identify untrue ideas or prejudice and better understand individual differences,” says Spape.
【1】How does AI prove its ability of identifying beautiful faces?
A．By becoming a tailor to attract individuals.
B．By making new images attractive to people.
C．By making decisions and identifying attractive attitude.
D．By helping people know more about what is attractive.
【2】Why is attractiveness a more challenging task?

A．The future research may involve cognitive functions.
B．Al knows the standard for personal and subjective attractiveness.
C．People can identify and understand individual differences.
D．Attractiveness can help the researchers make more decisions.
【4】Where is this text most likely from?

24、Nature has inspired researchers to develop a robotic gripper（抓取器）that behaves like an elephant's trunk(象鼻)to pick up and put down objects without breaking them. The University of New South Wales(UNSW)Sydney researchers sail the technology could be widely applied in industries where breakable objects are handled, such as agriculture, food and the scientific exploration industries—even for human rescue operations.
Dr Thanh Nho Do, UNSW Medical Robotics Lab director, said the gripper could reach consumers in the next 12 to 16 months if his team found an industry partner. “Our new soft fabric gripper is thin, flat, lightweight and can grip various objects—even in narrow spaces—for example, a pen inside a tube,” Dr Do said. “This gripper also has an improved real-time force sensor which is 15 times more sensitive than traditional designs and detects the grip strength required to prevent damage to objects it’s handling. The gripper body can change, enabling it to hold objects of various shapes and weights.”
Dr Do said the researchers found inspiration in nature when designing their soft fabric gripper. “Animals such as an elephant use the soft structures of their bodies to hold objects. These animals can do this because of a combination of highly sensitive organs, the sense of touch and the strength of thousands of muscles without bone—for example, an elephant's trunk has up to 40,000 muscles. So, we wanted to copy these gripping abilities,”he said.
Dr Do said the researchers' new soft gripper was an improvement on existing designs that had disadvantages that limited their application. “Many soft grippers are based on human hand-like structures with multiple inward-bending fingers, but this makes them unsuitable to grip objects that are strangely shaped, heavy or big, or objects smaller or larger than the gripper’s opening. Many existing soft grippers also lack the ability to provide sensory information and flexibility, which means you can’t use them with breakable objects or in narrow spaces,” he said. “Our technology can grip long objects and get them from narrow spaces, as well as get into holes to pick up objects.”
【1】What is Dr Thanh Nho Do's team trying to do at the moment?
A．Put the gripper on the market.
B．Partner with agriculturalists.
C．Perfect the gripper.
D．Increase their new products' sales.
