Face shape lets Al spot rare disorders
People with genetic syndromes (综合征)sometimes have revealing facial features, but using them to make a quick and cheap diagnosis can be _______given there are hundreds of possible conditions they may have. A new neural (神经系统)network that analyses photographs of faces can help doctors _______ the possibilities.
Yaron Gurovich at biotechnology firm FDNA in Boston and his team built a neural network to look at the overall impression of faces and _______ a list of the 10 genetic syndromes a person is most likely to have.
They _______ the neural network, called Deep Gestalt, on 17,000 images correctly labeled to match more than 200 genetic syndromes. The team then asked Al to _______potential genetic disorders from a further 502 photos 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 _______ the neural network's ability to distinguish between the different genetic mutations (父异)that can lead to the same syndrome. They used photographs of people with Noonan syndrome, which can result from mutations in any one of five genes. Deep Gestalt correctly identified the genetic source of the physical appearance 64 per cent of the time. It's clearly not _______, but it's still much better than humans are at trying to do this.
As the system makes its assessments, the facial regions that are most helpful in the determination are _______ 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 about_______ . If faces can reveal details about genetics, then employers and insurance providers could, in principle, ________ use such techniques to have a ________ against people who have a high probability of having certain disorders. ________ , Gurovich says the tool will only be ________ for use by clinicians.
This technique could bring significant________ for those who have genetic syndromes. The real value here is that for some of these ultra-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. For some diseases, it will cut down the time to diagnosis dramatically. For others, it could perhaps add means of finding other people with the disease and, ________ , help find new treatments or cures.
1.A.convincing B.practical C.reliable D.tough
2.A.narrow down B.result in C.bring about D.arise from

I’m Dina Asher-Smith. Growing in Orpington, southeast London, I love being the hunter. The one in pursuit. In training, I’ll latch on to the boys and chase them down. Even when I was younger, I tended to race girls who were older than me — at 17 I was racing 30-year-olds. It’s where I’m comfortable. But the hunter can go on to become the hunted. And this year at the World Athletics Championships in Doha, Qatar, I won gold in the 200m. At 23, I became the first British woman to win a world championship sprinting (短跑) title. The morning after the race, I was in the media tent and was told that I’d been mentioned in the Parliament.
Track and field is a mental game. You’re in your own little world, competing to be the person who can run the fastest in a straight line. My job is to take my body to a place where I think it can’t do any more and then keep going. To do that, I need to know my strengths and weaknesses. People get caught up in embarrassment or shame when they’re not good at something, but I just don’t have that in me. I do have a voice in my head that tells me if I’m not good at things, but it doesn’t make me feel negative about myself I use it to identify where I can improve and then I just keep going to training every day.
I’ve inherited personality traits from my parents that help me in my career. My mum is excitable and when I’m on the track, I have her fire-wanting to go for everything. I always know when I finish a race that I can turn around and find her in the front row, jumping up and down. My dad is more reserved. He has a cool exterior and that’s useful for me when I need calmness. I know to look for him a few rows behind my mum. They gave me opportunities to try whatever I was interested in. When I wanted to try golf my dad bought me cut-down clubs and had me attempting to putt balls (推球入洞) in the back garden. My mum used to play hockey with me outside the house. They took me to so many clubs and classes.
I started training with my coach, John Blackie, in my mid-teens. We met when I was eight as he ran the kids academy at my running club. Along with my parents, the three of them always emphasized that they just wanted me to be happy. They never pushed me too early. And, as I’ve got older, I’ve realized that’s unique. When running became serious, I knew that if it all stopped being fun for me, I could stop doing it. They put Dina the person before Dina the runner. Yes, the public might be disappointed and the newspapers might have a pop (抨击), but my parents and friends are still going to love me, and my coach is still going to be there. That knowledge allows me to stay relaxed under pressure.
Being as prepared as I can be is crucial as it keeps me calm and able to deliver in the moment. When I was studying history at university, I’d choose exams over coursework because I knew I could put the work in and perform under pressure. I was studying heavy things every day, like people facing prejudice because of their skin, or women sacrificing their lives for others to have the right to vote. It made me realize how lucky I am that the thing that gets me most frustrated is somebody beating me on the track. While, yes, I make sacrifices-some easy, such as not drinking and going out, and some harder, like restricting the food that I eat — ultimately, what I do is entertainment.
Everyone’s asking me about Tokyo Olympics, but I’m more focused on today. It’s important for me to keep my hopes and dreams separate from other people’s. I’m grateful everybody wants me to do well, but my next step has to be for me, not anyone else.

During the outbreak of novel coronavirus, cities are locked down and borders are closed. Science, on the contrary, is becoming more open. And this "open science” is already making a difference.
Soon after the epidemic started in China, a research team from Fudan University in Shanghai successfully sequenced (测定序列)the DNA of the virus. But they didn't keep the information to themselves. Instead, they placed the sequences on GenBank, an open-access data platform, so researchers around the world could download them for free and start studying the virus.
Due to this openness, pharmaceutical companies across the globe arc now able to work at the same time to develop a vaccine (疫苗)."There may be room for multiple different vaccines for different purposes and different age groups,” Amesh Adalja, a senior scholar at the Johns Hopkins University Center for Health Security in the US, told Al Jazccra. "The bigger menu we have of vaccines, the more resilient (有 适应 力的)we'll be against coronavirus outbreaks in the future."
Major drug companies around the world arc also sharing their study results. Remdesivir, a drug originally developed by US company Gilead Sciences to treat Ebola, is found to be promising in fighting against the novel coronavinis. Currently, two trials of the drug arc already underway in China, and the results might be available as soon as April, according to The Verge.
This openness in science is going to be even more important in the future. “With climate change, increasing globalization, and population shifts, epidemics will not go away, and might even become more frequent,” Dan Barouch, a Harvard Medical School professor, told Harvard Magazine.
He said, “No one group can do everything. It has to be a coordinated approach. But I do think that the world has a greater sense of readiness this time to develop knowledge, drugs, and therapeutics (疗法)very rapidly.”
Every epidemic is indeed a crisis, but it can also be a learning opportunity. One redeeming (补偿的)factor of the COVID-19 outbreak is that it is helping science adapt for the better.
1.What does the article mainly talk about?
A.Coordinated efforts to fight the epidemic.
B.Something positive we've learned from the epidemic.
C.The significance of openness and sharing of scientific knowledge.
D.What needs to be done to prevent future epidemics.
2.What is the positive effect of the research team from Fudan University placing the genetic sequence of the virus onto GenBank?
A.They alerted the world to the danger of the virus.
B.They helped remove people's fear of the virus.
C.They showed the world how to produce a vaccine.
D.They invited collective efforts worldwide to develop a vaccine.
3.What is the author's purpose of mentioning Remdesivir in the text?
A.To introduce a possible cure for the epidemic.
B.To compare the treatment of Ebola and the novel coronavirus.
C.To prove that many drug companies readily share their discoveries-
D.To show that the novel coronavirus will soon be contained.
4.Which of the following would Dan Barouch probably disagree with?
A.Epidemics will be less frequent thanks to scientific development.
B.The world is becoming better prepared to deal with epidemics.
C.No single group can fight against the epidemics independently.
D.The increase in globalization may worsen future epidemics.

Let's take a look at some mask-related history.
1st century
In that era, many people in Roman Empire worked underground in mines to support their families. But most of them suffered from and even eventually died of respiratory (呼吸的) illnesses. To address this problem, Pliny the Elder (23-79 AD), a Roman philosopher and naturalist, recommended the use of animal bladder (膀胱)skins to stop dust from being breathed in. Although primitive, his idea was considered the very first recorded mask invention.
16th century
Early inventions did not stop with Pliny. Many centuries later, Italian artist and inventor Leonardo da Vinci (1452-1519), proposed using a woven cloth dipped in water over the face to protect against the poisonous chemicals.
19th century
The design of the mask look a big step forward in the 19th century. In 1848, American Lewis Hassley became the first person to patent (注册专利)a protective mask for miners, which was a milestone in face mask history. Masks at this stage were similar to gas masks. Later, in 1897, Polish-Austrian doctor Johann von Mikulicz-Radccki designed a simple mask composed of one layer of gauze (纱中1), recommending medical workers to wear it to prevent infection. That was the first recorded use of a surgical mask.
20th century
In 1910. an epidemic broke out in Northeast China. Chinese doctor Wu Liande designed a cheap face mask called "Wu's mask". Made of two layers of surgical gauze, it could be wrapped around the back of the head and tied in a knot. This mask was praised by experts around the world, as it was simple to manufacture (制作)and had a low production cost. Modem exploration
With several outbreaks of infectious diseases and the flu. and the rise of pollution caused by industrial waste, the materials in masks have continued to evolve to better protect its wearer. For example, in 2012 when China suffered from smog, mask models such as N95 and KN90. which can filter out this fine particulate (微 粒)mailer, became highly popular. In the future. masks will continue to improve, hopefully so will the habits of humans.

A couple of weeks ago, my grandfather was explaining his favorite expression. "Nothing is ever easy? The following day, as I tried to complete my day's work, I happened to notice a bumblebee(大黄蜂)on the skylight(天窗).The skylight was particularly high up, but I thought removing the bee would take no more than five minutes. An hour later, the bee still remained. All that had changed was that the living room was a mess and that 1 was dizzy from looking up into the sunlight. I did not expect to waste an hour on an insect so tiny, but by doing so, I understood what my grandfather meant.
It is not only time that we tend to underestimate — we don’t account for unexpected costs. We often imagine what can work in our favor but we seldom think of all the negative things that could a fleet us. However, it is important to remember that your day or week or year might nor go as planned, and that is completely normal. It is perfectly acceptable to feel challenged — even at a task you thought was simple — because that is part of life.
If you can accept that nothing will ever be easy, then life might seem slightly more manageable. In middle school. I thought high school might be easier because I could choose the classes I wanted to take. In high school I thought college might be easier because I could have a schedule(计划)best suited for myself. Yet each time, I was both wrong and disappointed. After accepting that school wouldn't(and shouldn't)be easy. I found myself with a more positive altitude and improved results.
Of course, there should be preparations made to account tor expenses or time. Doing so can only help you accomplish your goals in a better way. However, there is no need to beat ourselves up when something stands in our path. Maybe we cannot see a bee coming our way, but we can always give ourselves the extra time to catch it.
1.Why did the author mention his experience of removing a bee?
A.To share something unforgettable with us.
B.To lead us to what the author learned from it.
C.To show the unexpected costs it caused.
D.To tell us how easy it is to waste our rime.
2.Why do things often tum out to be different from what we expect?
A.We often don't take lime seriously.
B.We tend not to have enough money.
C.Unexpected things can happen.
D.It is easy to feel challenged.
3.According to the text, what does the underlined phrase "beat ourselves up" mean?
A.lo hit or kick ourselves hard, many times
B.to blame ourselves too much
C.to encourage ourselves to work hard
D.to give up ourselves
4.What is the author's purpose of writing this article?

Researchers have been looking forward to using tiny flying robots to settle important tasks. The various machines could be used to help astronauts on space missions, and even to help bees with plant pollination(授粉). However, fitting the heavy electric equipment that is used to power and control the wings into the tiny robot has been challenging. Now thanks to RoboBee X-Wing—the world’s lightest aerial vehicle that can fly not tied to a power source.
Made by Harvard researchers, the insect-inspired robot weighs only 259 milligrams, has four wings whose distance is 3.5 centimeters, and stands 6.5 centimeters high. Its four small wings, which can flap up(拍动) to 170 times a second, are controlled by actuators(驱动器). They become small when the electricity passes through them. Six small solar cells, fitted above the wings to prevent them from disturbing the flight, provide the power.
RoboBee X-Wing is powered by six solar cells. To test its flying abilities, the team, led by doctor Noah Jafferis and PhD student Elizabeth Helbling, exposed the RoboBee X-Wing’s solar cells to LED lighting. To their delight, the tiny robot’s wings began to flap, and it rose, keeping a flight for about half a second. Though the robot lost its flight ability as soon as the power source was turned off, its short flight was cheered for its huge effect on the future of tiny flying robots.
However, though the current RoboBee X-Wing is a step in the right direction, it is not quite ready for main time. The researchers also hope to experiment with other power sources, such as batteries, sun light or radio frequency signals, and to add more advanced “brains” and sensor systems to navigate and complete tasks independently.
1.What can we know about small flying robots according to the first paragraph?
A.They are made to do ordinary tasks by scientists.
B.They can be used only for very dangerous task.
C.They can be powered directly by the energy of the sun.
D.It’s not easy to fit the heavy electric equipment into them.
2.Why is RoboBee X-Wing considered having a big effect on the future of tiny flying robots?
A.Because it is ready for the instant use.
B.Because it can take off and fly out of control.
C.Because it can fly not tied to a power source.
D.Because it can settle important tasks.
3.Which of the following is TRUE about RoboBee X-Wing?
A.It can’t be used in crowded places.
B.It can be used for giving directions.
C.It can use radio signals to power itself.
D.It still can’t be used widely at present.
4.In which section of a newspaper may this text appear?

The United States has about 475,000 school buses ---all painted yellow. Each day they carry more than 25,000,000 children, half of all schoolchildren in the country. But these buses, on average, use four liters of diesel (柴油) fuel to travel less than sixteen kilometers. When the school year began last fall, diesel averaged 55 cents a liter nationally. The price nearly doubled, to a dollar and 8 cents, by the end of school in June.
Bob Riley speaks for the American School Bus Council. He says fuel prices for schools are not much lower than others have to pay. As a result, schools are looking for ways to reduce transportation costs. Bus routes are being redrawn or, in some cases, canceled. Some areas are buying buses that use natural gas or other alternative fuels. Other steps include fewer field trips and less travel by sports teams. And some school districts may end any bus service not required by law.
Studies show that school buses are the safest form of transportation to and from school. The American School Bus Council says cuts in bus service are bad for children and possibly the environment. It says removing buses from the road will mean an increase in other vehicles transporting students. Spokesman Bob Riley says another concern is that reducing bus services might reduce attendance.
But it could also get more children to walk or bicycle to school. And that would surely make people happy at the National Center for Safe Routes to School. More kids walking or biking safely to school is the aim of a three-year-old federal program, part of an international movement. The goal is to increase physical activity and reduce air pollution. The United States will celebrate Walk to School Day on October eighth this year. But for some students, high fuel prices could make every day a walk-to-school day.
1.What does this passage mainly tell us?
A.High fuel prices’ influences on school buses.
B.New measures to transport school students.
C.The safest form of student transportation.
D.The origin of Walk to School Day.
2.What can we learn from Paragraph 3?
A.Cuts in bus service will have negative results.
B.The US government is encouraging cuts in bus services.
C.The US schools are searching for the safest transportation means.
D.Reducing bus service will do a lot of good to the environment.
3.In order to cut down transportation cost, many schools take the following measures EXCEPT__.
A.changing some bus routes
B.stopping some bus routes
C.asking parents to drive children to and from school
D.using other types of fuels
4.The National Center for Safe Routes to School encourages more children to walk or bike to school in order to ____.
A.save more fuels and diesel for the country
B.keep the children safe on their way to school
C.make the children live a simple life
D.keep the children healthy and the environment clean

Most people know that Marie Curie was the first woman to win the Nobel Prize, and the first person to win it twice. However, few people know that she was also the mother of a Nobel Prize winner.
Born in September, 1897, Irene Curie was the first of the Curies’ two daughters. Along with nice other children whose parents were also famous scholars, Irene studied in their own school, and her mother was one of the teachers. She finished her high school education at the College of Sévigné in Paris.
Irene entered the University of Paris in 1914 to prepare for a degree in mathematics and physics. When World War I began, Irene went to help her mother, who was using X-ray facilities (设备) to help save the lives of wounded soldiers. Irene continued the work by developing X-ray facilities in military hospitals in France and Belgium. Her services were recognised in the form of a Military Medal by the French government.
In 1918, Irene became her mother’s assistant at the Curie Institute. In December 1924, Frederic Joliot joined the Institute, and Irene taught him the techniques required for his work. They soon fell in love and were married in 1926. Their daughter Helene was born in 1927 and their son Pierre five years later.
Like her mother, Irene combined family and career. Like her mother, Irene was awarded a Nobel Prize, along with her husband, in 1935. Unfortunately, also like her mother, she developed leukemia because of her work with radioactivity (辐射能). Irene Joliot-Curie died from leukemia on March 17, 1956.
1.Why was Irene Curie awarded a Military Medal?
A. Because she received a degree in mathematics.
B. Because she contributed to saving the wounded.
