21、A drug designed entirely by artificial intelligence is about to enter clinical human trials for the first time. The drug, which is intended to treat obsessive-compulsive disorder ( OCD)(强迫症),was discovered using Al systems from Oxford-based biotech company Exscientia. While it would usually take around four and a half years to get a drug to this stage of development, Exscientia says that by using the Al tools it's taken less than 12 months.
The drug, known as DSP・1181, was created by using algorithms (算法)to examine potential compounds (化合物),checking them against a huge database of parameters, including a patient's genetic factors. Speaking to the BBC, Exscientia chief executive Professor Andrew Hopkins described the trials as a “ key milestone in drug discovery “ and noted that there are “ billions” of decisions needed to find the right molecules (分子)for a drug, making their eventual creation a “ huge decision. “ With Al, however, “the beauty of the algorithms is that they are unknowable, so can be applied to any disease.”
We've already seen multiple examples of Al being used to diagnose illness and analyze patient data, so using it to engineer drug treatment is an obvious progression of its place in medicine. But the Al - created drugs do bring about some relevant questions. Will patients be comfortable taking medicine designed by a machine? How will these drugs differ from those developed by humans alone? Who will make the rules for the use of Al in drug research? Hopkins and his team hope that these and a great many other questions will be explored in the trials, which will begin in March.
【1】What is special about the drug designed by Al?
A．It's a better cure for OCD.
B．It has no side effect on humans.
C．Its development takes less time.
D．It doesn't need clinical human trials.
【2】Which is a key factor in creating the drug according to Paragraph 2?
A．Trials.
B．Algorithms.
C．Compounds.
D．Molecules.
【3】How does Hopkins feel about the way of drug creation?
A．Optimistic.
B．Doubtful.
C．Disappointed.
D．Puzzled.
【4】What can be the best title for the text?
A．Medical Trials by Al
B．An Example in Medical Trials
C．A Creation in Al Development
D．Al - designed Drugs to Be on Trial
22、What it does
The self-cleaning door handle is combining with advanced photocatalytic ( 光 催 化 ) and blacklight technology. A light source activates the door’s handle coating, telling it to start cleaning. It can minimize the risk of infection by contact and improve the cleanliness of a space.
How it works
The working principle of the product is that a thin advanced photocatalytic coating can effectively decompose bacteria ( 细 菌 ) on the surface of a substance. A consistent UV light source—inside a transparent glass door handle—is required to activate the door’s handle coating on the outer surface for disinfection, so a generator is used to provide electricity to light up a UV LED lamp by the motion of an opening and closing door. Then, the door handle can clean by itself.
Design process
We made the first version by using stainless steel. However, it caused the door handle to be heavier. Then, we tried aluminum, which made it light and easy to fix. We also improved the generator output which effectively turned energy from door movement into a light source.
How it is different
Our innovative design is simple, effective, and attractive. It has an elegant smooth shape, and its minimalist appearance stands out in today’s world of inventions. Nowadays, people use chemical cleaning materials to clean up public areas but it harms the human body. Our design can be used for a long time and is effective. It can self-clean after each use. In the door lock and door handle market, it is a unique design because there are no similar products.
Future plans
In the future, we will commercialize the product and hope that it can compete on the market with similar products. We are going to connect with public properties, for example, shopping malls, hotels, hospitals and public restrooms, where the risk of spreading infection is higher.
Awards
In addition to winning the James Dyson Award, it has also received the Gold Award, and in 2016, it was featured in the 44th International Geneva Inventions Exhibition.
【1】How does the self-cleaning door handle function?
A．It controls the door movement automatically.
B．It minimizes the risk of infection by less contact.
C．Chemical cleaning materials are used to clean it up.
D．The light source tells the door handle coating to clean itself.
【2】Compared with the first version of the product, the present one is ______.
A．safer and cheaper
B．cleaner and easier
C．less heavy and more effective
D．more attractive and expensive
【3】What do we know about the new invention according to the passage?
A．It has been widely used in public areas.
B．It has received recognition for its innovation.
C．It is quite competitive among similar products.
D．It will replace traditional chemical cleaning materials.
23、 The AI project intends to use artificial intelligence to create an innovative (创新的) theatrical performance, which is expected to premiere (首演) early next year. Head of the research team Rudolf Rosa said: “The main idea behind our study came from Tomáš Studeník, an innovator who noticed the centenary of the play ‘RUR’ is approaching. “This was a key moment for robotics, as the idea of a robot, including the word ‘robot’ itself, was invented by Karel Capek and his brother Josef wrote this play.
“Tomáš believed this should be properly celebrated and formulated the idea of turning the story around: 100 years ago, a man wrote a play about robots; what if today, robots wrote a theatre play about men?”
While there are now numerous papers focusing on machine-produced art, including some where computational techniques were used to produce dialogues or story ideas for plays, the automatic generation of an entire theatrical performance is an extremely complex task never-before attempted.
Rosa’s team decided to split the production of their play into several sub-parts. Although other research teams have used this approach to generate dialogues, few have attempted to produce an entire play. Dr Rosa said: “Thanks to the approaching anniversary, our main target is clear and fixed: by January 2021, we need to have a play ready for premiere. As it will be performed by a professional theatre group, we need to have the script ready in September, so that there is enough time for rehearsals (彩排).”
The researchers started experimenting with pre-trained language model called GPT-2. Once adequately trained, GPT-2 is able to complete unfinished texts using similar language and covering related themes. For example, if GPT-2 is fed the first paragraph of a news article, the model will try to continue to write a few additional paragraphs on the same topic, using the existing text for inspiration, while generating sentences about new concepts.
【1】How did Rosa’s team plan to do the project?
A．By cooperating with other research teams.
B．By dividing their work into few small sections.
C．By exploring the possibility of creating dialogues using AI techniques.
D．By staging an entire play directly performed by professional theatre group.
【2】What can be learned from the text?
A．The play will be on show in September.
B．GPT-2 can perform an entire play with ease.
C．Machines are still not smart enough to create art.
D．AI techniques have been applied to create dialogues for plays.
【3】What does the text tell us?
A．GPT-2 can practice continuation writing.
B．The play RUR was written by Karel Capek.
C．The idea of a robot was born half a century ago.
D．The word “robot” was coined by Tomáš Studeník.
【4】What may be the best title for the text?
A．“Robotre” Staged Successfully
B．“Mechatre” Trained Inadequately
C．“Mantre” Story Completed by Humans
D．“AItre” Play Written Entirely by Machines
24、How many times have you wondered about how much better things might have been if the younger you had made different decisions? Or, have you breathed a sigh of relief when you recognize that one of your lucky choices ended up much better off than you might have been, if things had gone a different way?
【1】It is the birthplace of emotions such as regret, gratitude, and guilt. Picturing an alternative outcome to what has actually happened in one’s life holds an irresistible appeal, even when it leads to unhappiness. It is therefore not surprising that it has become a hot topic of research in social psychology.
Counterfactual thinking often plays out in real-time on national television after a natural disaster.【2】 The victims are usually shaken and highly emotional, and they have often lost everything that they owned. And yet, we commonly hear them use words such as “lucky” or “grateful” to describe their feelings.
【3】 If the person had really been lucky, wouldn’t they still have a house and have been spared from all of the grief they must now endure? Some psychologists have argued that one of the benefits of counterfactual thinking is that it can be an effective tool for making us more resilient (迅速复苏的). 【4】 That paves the way for positive emotions that might help them through a very dark time in their lives.
Counterfactual thinking is simply part of who we are. 【5】 Many psychologists believe that it exists to helps us crystallize (变明确) the goals that are most important to us and to improve our ability to wisely choose future courses of action.
A．At first glance, this response does not make much sense.
B．This type of mental “what-ifism” is called counterfactual thinking.
C．Even though it sometimes makes us sad, it can also do us some good.
D．The imagination of a life has been the inspiration for dozens of movies.
E．News reporters frequently interview survivors who have barely escaped with their lives.
F．The more important the event is, the more intense our counterfactual thinking about it will be.
G．The mind of the counterfactual thinker can easily imagine circumstances that would have been even worse.
