21、The National Hurricane Centre, lying in Miami, Florida, gives watches and warnings before hurricanes come near the coastline. They use computers with satellite images (卫星影像) to find out where and when a hurricane will hit the coast. Sometimes, if a hurricane is strong enough, officials may require people to leave their homes, and travel to a safer place.
Can you imagine flying a plane through a hurricane? If you’re a hurricane hunter, it’s your job! Hurricane hunters fly airplanes to help the National Hurricane Centre make predictions (预测) about hurricanes, and give them the information needed to give warnings. Pilots find out how fast the winds are blowing, how big the hurricane is, and which direction it’s moving in. This helps people to be better prepared for hurricanes as they come near the coastline.
Categories (类别) of Hurricanes
There are five categories of hurricanes. The categories help to make people know how much damage a hurricane may cause because the greater the wind speed, the more dangerous the storm.
Category 1 - Winds 74-95 mph
Winds break branches, pull trees out of the ground and overturn mobile homes.
Category 2 - Winds 96-110 mph
Winds are strong enough to destroy weak doors and windows, and create 8-foot ocean waves.
Category 3 - Winds 111-130 mph
Strong winds cause major flooding near the coast which can destroy homes and businesses.
Category 4-Winds 131-155 mph
Winds are strong enough to destroy some buildings and cause heavy damage to building roofs .
Category 5 - Winds greater than 155 mph
Buildings along the coastlines are washed away. Buildings can be completely destroyed.
【1】What is the first paragraph mainly about?
A．Hurricane predictions.
B．The job of National Hurricane Centre.
C．Hurricane safety guides.
D．The advice of National Hurricane Centre.
【2】What does hurricane hunters do?
A．They help people out in a hurricane.
B．They predict the paths of hurricanes.
C．They collect information about hurricanes.
D．They warn of possible hurricane dangers.
【3】What can Category 2 hurricanes cause?
A．They can bring about great flooding.
B．They can blow roofs off buildings.
C．They can break weak doors.
D．They can destroy the buildings completely.
22、The fast spread of the virus has led most Chinese citizens to wear face masks in public to help reduce infections. The Beijing-based Hanwang Technology Ltd. says it has created a new facial recognition system that is the first to effectively identify people even if they are wearing masks.
China is recognized as a world leader in the development of artificial intelligence and facial recognition system. The new system is based on the existing technologies developed over the past 10 years.
“When wearing a mask, the recognition rate can reach about 95 percent, which can ensure that most people can be identified,” Hanwang’s vice president, Huang Lei, said. He added that the system’s success rate for people not wearing a mask is about 99.5 percent. However, the new system struggles to identify people wearing both a mask and sunglasses. “In this situation, all of the key facial information is lost. In such cases recognition is tough,” Huang said.
Hanwang is now selling two main kinds of products that use the technology. One performs “single channel” recognition and the other is a “multi-channel” recognition, which can identify individuals in a crowd of up to 30 people “within a second”.
Huang said officials can use Hanwang’s technology to compare images with ministry (部门) records on individuals in order to identify and track people as they move about. The system can identify crime suspects (嫌疑人), terrorists or make reports or warnings, he added.
While some citizens have expressed doubt to such tools, more people seem to have accepted the methods as a way to deal with the current health emergency.
So far, Huang says most interest in the new system has come from within China. But he sees the interest likely expanding if the virus continues to spread and the use of face masks increases.
【1】What is special about the new facial recognition system?
A．It has no relation to the existing tech.
B．It is being used both at home and abroad.
C．It can record people’s temperature.
D．It can identify people even if they’re wearing masks.
【2】According to the passage, the new system will probably be most helpful for ________.
A．international companies
B．colleges and universities
C．the Ministry of Public Security
D．the Ministry of Finance
【3】What’s most people’s attitude towards the use of the new system?
A．Supportive.
B．Disapproving.
C．Uncaring.
D．Doubtful.
【4】What’s the purpose of the passage?
A．To show China’s technological advances.
B．To introduce a newly developed system.
C．To demonstrate the innovation of China.
D．To advertise a new tech-based product.
23、AI can identify rare genetic disorders
People with genetic syndromes (基因遗传综合症) sometimes have revealing facial features, but using them to make a quick and cheap diagnosis can be tricky when there are hundreds of possible conditions they may have. A new neural(神经的) network that analyses photographs of faces can help doctors narrow down the possibilities.
Gurovich at biotechnology firm FDNA in Boston and his team built a neural network to look at the gestalt (形态)– or overall impression of faces and return a list of the 10 genetic syndromes a person is most likely to have.
They trained the neural network, called DeepGestalt, on 17,000 images correctly labeled to correspond to more than 200 genetic syndromes. The team then asked the AI to identify potential genetic disorders from a further 502 photographs of people with such conditions. It included the correct answer among its list of 10 responses 91 per cent of the time.
Gurovich and his team also tested the AI’s ability to distinguish between different genetic mutations (突变) that can lead to the same syndrome. They used images of people with Noonan syndrome, which can result from mutations in one of five genes. DeepGestalt accurately identified the genetic source of the physical appearance 64 per cent of the time.
“It’s clearly not perfect,” says Gurovich. “But it’s still much better than humans are at trying to do this.”
As the system makes its assessments, the facial regions that were most helpful in the determination are highlighted and made available for doctors to view. This helps them to understand the relationships between genetic make-up and physical appearance.
The fact that the diagnosis is based on a simple photograph raises questions of privacy. If faces can reveal details about genetics, then employers and insurance providers could, in principle, secretly use such techniques to discriminate against people with a high probability of having certain disorders.
However, Gurovich says the tool will only be available to doctors. Christoffer Nellaker at the University of Oxford says this technique could bring significant benefits for those with genetic syndromes.
“This is not fundamentally different information than we’re sharing walking down the street, or we’re happy to share with Facebook or Google,” he says. “But questioning the data in this way means you can obtain information about health or disease status.
“The real value here is that for some of these extreme rare diseases, the process of diagnosis can be many, many years. This kind of technology can help narrow down the search space and then be confirmed through checking genetic markers,” he says.
For some diseases, this kind of technology will cut down the time to diagnose thoroughly. For others, it could perhaps add a means of finding other people with the disease and, in turn, help find new treatments or cures.
【1】What is the purpose of Gurovich’s neural network?
A.To test the AI’s ability.
B.To analyze photographs of faces.
C.To help doctors reduce the range of the diagnosis.
D.To research the overall impression of patients’ faces.
【2】What disadvantage does Deep Gestalt bring?
A.It will probably involve in the people’s privacy.
B.It cannot provide information about health or disease.
C.The diagnosis based on a simple photograph is not accurate.
D.It could perhaps add a means of finding other people with the disease.
【3】What can we learn from the passage?
A.The result of the assessments for this system is perfect.
B.Deep Gestalt can correctly label 200 genetic syndromes.
C.It seems doubtful to use AI to distinguish genetic mutations.
D.This kind of technology can speed up the diagnostic process.
【4】What is the author’s attitude to this technique?
A.Supportive. B.Puzzled.
C.Doubtful. D.Negative.
24、I was at my parent’s dinner table. Before me was a worn journal of thin and discolored pages. It was my grandfather's journal and now belonged to my father. My grandfather had passed away in the months leading up to my birth. I never got to visit the places he had frequently and people who had been a part of his life’s journey.
I was now about to enter his world, through the words he had left behind. Within minutes, I was attracted by the power of the written words. In the magical script before me, I was transported to another age when food was an everyday art, planned, prepared and enjoyed in the company of others, and a time when people had the heart to pause，their own lives to embrace (拥抱）each other’s struggles. All this was conveyed to me in the beauty of the words that flowed together to connect with the writer’s mind and understand the world they lived in.
That kind of writing seems to be lost on us today. We have gotten used to writing in bite-sized pieces for a public looking for entertainment, and hungry for information. No wonder, there are nearly 200 million bloggers on the Internet and a new blog is created somewhere in the world every half a second. Instead of adding to our collective wisdom, most of these writings reflect the superficiality (肤浅)and impatience of our day and age.
This not only robs us of the skill of writing impressive essays, it also prevents us from exploring what is truly important. Writing humbles us in a way that is vital for our character growth, by reminding us about the limits of the self and our appropriate place in the vast flow of life. Writing frees us by helping us explore the unknown so that we truly open up to the magic of the world around us. I saw all of this in the writing s of my grandfather. And I’ve seen it again and again in the writings of the greatest thinkers of humanity. Their writings reflect deep thought on issues of human importance.
【1】Why does the author begin the text with her grandfather’s journal?
A. To show her respect for her grandfather.
B. To present the importance of good writings.
C. To raise the problem of today’s writing.
D. To express her great interest in the journal.
【2】What did people use to do in the author’s grandfather’s age?
A. They used to live a hard life.
B. They cared about each other.
C. They were fond of writing.
D. They taught kids how to cook.
【3】What does the third paragraph mainly discuss?
A. The current situation of public writing.
B. The large number of blogs on the net.
C. People’s lack of wisdom nowadays.
D. The information age we are living in.
【4】What does the author try to convey in the last paragraph?
A. To express her eagerness to learn writing skills.
B. To show her reflection on humanity in her age.
C. To discuss what good writings should be like.
D. To stress the effect of her grandfather’s journal on her.
25、On June 18th, 15-year-old Clara Daly was seated on an Alaska Airlines flight from Boston to Los Angeles. Suddenly, a flight attendant asked a(n) _______ question over the loudspeaker: “Does anyone on board know American Sign Language? ” Clara _______ the call button. The flight attendant came by and explained the situation. “We have a passenger on the plane who is blind and deaf,” she said.

So she unbuckled (松开) her seat belt, walked toward the front of the plane, and _______ by the aisle seat of Tim Cook. Gently _______ his hand, she signed, “How are you? Are you OK? ”Cook asked for some water. When it arrived, Clara returned to her seat. She _______ again a bit later because he wanted to know the time. On her third visit, she stopped and stayed a while. “He didn’t need anything. He was ________ and wanted to talk.” Clara says.
So for the next ________ , that’s what they did. She talked about her family and her plans for the future. Cook told Clara how he had ________ become blind over time and shared stories of his days as a traveling salesman. Even though he couldn’t see her, she looked attentively at his face with such kindness, a passenger reported. “Clara was ________” , a flight attendant told Alaska Airlines in a blog interview. “You could ________ Tim Cook was very excited to have someone he could speak to, and she was such an angel.”
