21、 Artificial intelligence (AI) （人工智能）is the ability of a computer program or a machine to think and learn. It is also a field of study that tries to make computers "smart". John McCarthy, a scientist, came up with the name "artificial intelligence" in 1955. Many things such as learning and problem solving can be done by computers, though not in the same way as we do.
An unusual goal of AI research is to create computer programs that can learn, solve problems, and think logically（逻辑地）. At present we use the term Al for successfully understanding human speech, recognizing（识别）human faces, operating self-driving cars and competing in some game systems like Chess and AlphGo（阿尔法狗）. Some people also consider AI a danger to humans if it develops too quickly. Professor Stephen Hawking, a well-known British scientist, was not for this kind of technology.
Math is the basic language of AI. If we raise the standard in the learning of math, our students will be more likely to become successful AI designers in the future. We not only want bright students, but also need to attract average students and give them the math skills which are needed to change them into AI designers. Besides, a good knowledge of computer science is also necessary for AI designing.
Scientists hope to create creative and emotional AI which can possibly understand human feelings or create art. Many ways and tools have been tried to discover this fascinating field.
【1】From Paragraph 1, we know that_________.
A．all problems can be solved by AI
B．machines with AI can think and learn
C．AI has been around for only 60 years.
D．AI works in the same way as humans
【2】The underlined word "it" in Paragraph 2 refers to（指的是）_________.
A．Chess
B．AlphaGo
C．the danger
D．AI
【3】According to the writer and the following school report, which student will most probably become a successful AI designer?
School Report
A．Mike.
B．Peter.
C．Amy.
D．Cathy.
【4】Paragraph 4 mainly tells us the scientists’ ________ about AI.
A．wishes
B．worries
C．feelings
D．discoveries
22、With greater climate catastrophe (气候突变) on Earth, it is natural for us to make every effort to stop the potential floods, snowstorms, and alarming reports from scientists. For many of us (myself included), part of that means running out to buy reusable straws, organic cleaners, and packaging-free products.
However, before you are delighted at “green” purchases, take a second to consider the results of a new study from Arizona University. By comparing the shopping habits, mental health and environmental impact of young people, the researchers reconfirmed a principle: Buying less beats buying “green” stuff without effort. And that is true whether you are looking at the impact that your purchases have on the Earth or on your own happiness.
It should not come as a shock that simply consuming less is better for the planet. After all, every new item a factory yields requires some resources to produce. Take plastic bag bans for instance. If your city is getting rid of single-use shopping bags, it can be attractive to pay for a fashionable organic cotton bag hanging in the check-out line of your local supermarket. However, experts insist that growing cotton is actually no better for the Earth than producing the conventional plastic bags. Then what is your best bet for carrying your groceries if you care about sustainability? Any bag you already own.
It is not just the Earth that will be happier if you buy less. You will feel more contented too, according to the new study. “People believe that they might well be self-satisfied about becoming environmentally conscious through ‘green’ buying patterns, but it doesn’t seem to be that way”, said the lead researcher Sabrina Helm. “Reduced consumption has effects on increased well-being, but we don’t see that with ‘green’ consumption.”
“Owning every new ‘green’ product on the market might make you feel contented, but if you relieve yourself of that burden of ownership, most people report feeling a lot better,” said Helm.
【1】Why does the writer mention “green” shopping habits?
A．To call on a green lifestyle.
B．To praise people’s green efforts.
C．To introduce a social trend.
D．To present a half true “green” truth.
【2】What’s the main idea of paragraph 3?
A．The plastic bag bans are of no effect.
B．Using any bag you have is the best bet.
C．Reduced consumption is better for the Earth.
D．Growing cotton is far worse for the Earth.
【3】What does the underlined word “that” in paragraph 4 refer to?
A．The sense of achievement.
B．The sense of happiness.
C．The sense of relief.
D．The sense of security.
【4】What might be the best title for the text?
A．Less is More
B．The Greener, The Happier
C．Happiness Guarantee
D．What Are Green Products?
23、Aspirin was discovered in 1897, and an explanation of how it works followed in 1995. That, in turn, has encouraged some research leads on making better pain relievers through something other than trial and error. This kind of discovery—answers first, explanations later—is called “intellectual debt”. We gain understanding of what works without knowing why it works. We can put that understanding to use immediately, and then tell ourselves we’ll figure out the details later. Sometimes we pay off the debt quickly; sometimes, as with aspirin, it takes a century; and sometimes we never pay it off at all.
In the Age of Intelligence, while machine learning presents lots of problems and gets things wrong, at least we know enough to be wary of the predictions produced by the system and to argue that they shouldn’t be blindly followed: but if a system performs perfectly (and we don't know why), then we come to rely on it and forget about it and suffer consequences when it goes wrong.
It’s the difference between knowing your car has faulty brakes and not knowing: both are bad, but if you know there is a problem with your brakes, you can increase your following distance, drive slowly and get to a mechanic as soon as possible. If you don't know, you're likely to find out the hard way, at 80mph on the highway when the car in front of you came to a sudden stop and your brakes give out.
We don’t have much by way of solutions. Most important, we shouldn’t trick ourselves into thinking that machine learning alone is all that matters. Indeed, without life value, machine learning may not be meaningful answers at all.
【1】What is the purpose of mentioning aspirin in the first paragraph?
A．To present the research process of aspirin.
B．To introduce a similar situation machine learning faces.
C．To show the difficulty in explaining how aspirin works.
D．To prove we can use something even when we don't understand.
【2】What does the underlined word “wary” probably mean in the second paragraph?
A．Negative.
B．Doubtful.
C．Anxious.
D．Watchful.
【3】How does the writer prove that it's potentially worse if a system performs perfectly?
A．By giving a definition.
B．By making comparison.
C．By doing an experiment.
D．By telling a story.
【4】Which of the following statements is the writer likely to agree with?
A．It’s impossible to pay off Intellectual debt.
B．It’s wise not to rely on machine learning.
C．It makes sense to prepare for danger in times of safety.
D．It’s OK as long as a system works well.
24、Small talk, also called chitchat, is short conversations people have with others, while they wait in line at the store, at family events or work. Many people find these small conversations about random topics difficult. Some people say they hate it. Others say small talk is a waste of time. They may even call it idle chitchat or idle chatter, meaning it doesn’t do anything, so they think little of it.【1】.
These exchanges can open doors that may lead to larger, more meaningful conversations. When you first meet someone or talk to someone you don’t know well, it would be awkward to begin a conversation about a really deep topic.【2】Let’s say you make small talk with someone at a party. But they only want to talk about their cats. Then you can talk about animals together first, which may lead the conversation to the way you want.
【3】Chatting with a colleague about his child may help you to understand more of his life outside the office. This could help build healthy work relationships.
Small talk could even help your larger communities----your relationships with neighbors and colleagues. Exchanging a recipe with a neighbor may make her noises upstairs easier to live with.
【4】Most people said they do not talk to strangers while travelling on a subway. Researchers at the University of Chicago then asked some participants in a study to talk to people while communicating to work on a train. They found that those who made small talk with strangers were happier than those who sat alone.【5】Maybe your life will become more cheerful just because of it.
A．Small talk may make you happier.
B．So why not try talking to someone?
C．Small talk can give you the chance to start.
D．However, some people are not good at small talk.
E．However, small talk is of great importance to everyone.
F．Small talk can also increase your feeling of understanding.
G．It’s easy to start a conversation by sharing the same experience.
