21、 Some young people win attention because of their good looks or their singing ability. A much smaller number gain fame because they have done something important and worthwhile with their abilities. Rishab Jain is among the latter. In 2018, 13-year-old Rishab developed a way to use AI technology to help pancreatic(胰腺的) cancer patients and won the 3M Young Scientist Challenge, a nationwide middle-school science competition, and its $25,000 prize.
In the last stage of the contest, Rishab competed against nine other finalists at the 3M Innovation Center(创新中心) in St. Paul, Minnesota. Leading up to the big meet, each finalist had partnered with a scientist to further develop their inventions.
Rishab explains what led him to create his invention. First, a family friend died of cancer. Then Rishab learned about how deadly pancreatic cancer is, and that its low survival rate is due to how difficult it is to treat. "I'm also into programming, so I was learning about AI technology. I decided to try to solve a real-world problem using it."
His winnings have been put in further research and in his nonprofit Samyak Science Society, which helps poor children enter the STEM (science, technology, engineering and math) education. Rishab is also raising awareness about pancreatic cancer. These efforts make him quite different from teenagers of his age. Considering becoming a biomedical engineer or a doctor一or both, he has also put some money aside to further his own learning. Almost certainly the doors of higher education will open wide to him before he even knocks.
That's an outstanding outlook for one so young. Rashib is committed to helping very sick people in need. He is also providing teenagers of his age with a much-needed model of what kinds of things youth can achieve.
【1】What can we learn about the 3M Young Scientist Challenge in 2018?
A．It was intended to solve medical problems.
B．It was a nationwide AI competition for teenagers.
C．It offered the finalists an opportunity to work with scientists.
D．It allowed the finalists to learn AI technology in the 3M center.
【2】How did Rishab win the 3M Young Scientist Challenge?
A．He showed excellent programming ability.
B．He figured out the survival rate of pancreatic cancer.
C．He introduced poor children to STEM education.
D．He applied AI technology to treating pancreatic cancer.
【3】Which of the following best describes Rishab?
A．Talented and caring.
B．Independent and humorous.
C．Responsible and patient.
D．Polite and inspiring.
22、In my years in the classroom, I have had the pleasure of teaching several children who have either one or two artists as parents. These children, who have a higher than average exposure to art and the media for creating it, possess some qualities that many other children do not have: in addition to their artistic talent, I have observed that they usually read and write better than their peers. My conclusion is that their exposure to art affects other aspects of their learning.
I suggest that parents expand their definition of art. If you are a baker or a cook, or if you like to arrange flowers, you are an artist. These expressions of creativity are as valuable as those of painters and the other people we call artists. If you are a scientist and enjoy inventing and experimenting, you may include yourself in the definition of "artist".
Art is a delightful way through which you can record the development of your child's growth. Just as you will notice that writing and reading improve with age, so does artwork. The role of parents and teachers is to expose children to a variety of materials so that they can create art. Once the variety is offered, children will then have a choice as to whether they want to use the materials or not.
Creating art is a fine way for children to make choices and solve problems. Every step involves making a decision: what color to use, how to make a line, what size to make something. With every choice, the object becomes more and more their own.
Everyone has an imagination. Art takes it a step further. Through art, children create something that, until that point, was only imagined. Thus, they create visual presentation of abstract ideas.
Children who may be having difficulties in other parts of the school curriculum may find an expressive outlet through art. It's a way to uncover talent that may not be seen otherwise. Art is a means of communicating ideas, feelings, and solutions in a way other than verbally or written.
Families can create a harmonious balance in their children's lives when they make plans for the arts. Be there to appreciate and encourage them during every step of the creative process.
【1】What has the author found through his teaching career?
A．Kids are more likely to be affected by their parents.
B．Artistic talent is the most important quality of kids.
C．Kids whose parents are artists can usually read and write better.
D．Learning art can make kids have easy access to success.
【2】What does the author want to tell us in paragraph 2?
A．The definition of art is broad.
B．It's easy to work as an artist.
C．Artists are full of creativity.
D．Scientists are similar to artists.
【3】What should parents do to develop kids' art?
A．Set an example to their kids.
B．Help them make their decisions.
C．Inspire their imaginative ability.
D．Expose them to various materials.
【4】What does the text mainly talk about?
A．Advice on kids' colorful life.

23、MIT chemistry professor Daniel Nocera led research on the artificial leaf project, says he and his colleagues took their cues from plants, which are literally buzzing with electricity.
“What happens is that sunlight comes in and hits the leaf and then the leaf immediately takes that sunlight and makes a wireless current,”says Nocera.
During photosynthesis, the energy in sunlight splits water molecules into hydrogen and oxygen. The hydrogen joins with carbon dioxide to make sugar, an essential fuel for plant growth. In Nocera’s laboratory, scientists replicated that chemical process using a silicon device about the size and shape of a playing card, only thinner. It's coated with nickel and cobalt catalysts that when exposed to water and ultraviolet light, accelerate a chemical reaction.
“So you can literally just take this bottle of water and we could take the chip, put the chip inside the bottle of water, and go holding it up in the sun and you would start seeing hydrogen and oxygen bubbles coming up.”
The hydrogen is then recombined with the oxygen in a fuel cell to produce electricity. Nocera’s work builds on previous research. John Turner of the National Renewable Energy Laboratory pioneered the concept in 1998 using materials too expensive and unstable for commercialization.
Nocera says his so-called practical artificial leaf uses less expensive materials, is more stable and more efficient than that earlier design. He says the challenge is to collect the gases coming off the silicon and store them until the energy is needed. “That has to be engineered still,” he adds. “We don't know how to do that. It will be something that we will start doing pretty soon. You’ll be storing a fair amount of energy because this system is working at the efficiency more or less of the solar cell.”
In laboratory experiments, Nocera's solar cell prototype operated continuously for 45 hours without a drop in electrical output. Nocera notes that it works in any type of water. “So you can use natural water sources, which for us is a big deal, because if you are in rural parts of the world. especially where they are poor, it is really costly to bring in pure water and so, the fact that you can go over there' to a puddle and pick the water up and begin using it, is something that is very powerful for us."
Nocera believes the artificial leaf could be especially useful as an inexpensive source of electricity for low-income populations in developing countries. The goal, Nocera says, is to make each home its own power station. He predicts a commercial version of the artificial leaf will be on the market within three years.

【4】What is probably the best title of the passage?
A．Plants Can Produce Cheap and Steady Electricity
B．Storage of Energy Is a Tough Challenge
C．Artificial Leaf Tuns Sunlight into Electric Power
D．Inexpensive Source of Electricity Is Finally Available
24、Damage to Ozone layer Gets Worse
In the middle of winter, when snow is falling in many parts of the United States, scientists have sounded a warning to people who plan to spend many hours in the sun this summer. The warning is: The sun’s summertime rays are more dangerous than once thought.
A team of scientists from 80 nations recently reported to the United Nations that a layer of ozone (臭氧层) in the atmosphere, which protects humans from harmful levels of ultraviolet（紫外线） radiation, will be thinner over the United States this summer. The thinner layer allows more ultraviolet rays from the sun to reach Earth. The extra amount of ultraviolet radiation could cause an increase in the number of cases of skin cancer.
Scientists first became concerned about the ozone layer in the mid-1980s when a hole was discovered in the layer above Antarctica during the winter. The hole was caused by chemicals used in refrigerators and air conditioners. When these chemicals are sent out into the atmosphere, they produce gases that destroy the ozone.
Concern about the protective ozone layer rose more recently when data(数据) from satellites and ground stations showed that ozone levels were dropping over areas other than Antarctica. Low ozone levels were recorded in the spring and summer over the United States and over other populated areas in the world.
Although many countries have already begun stopping the use of ozone destroying chemicals, the new findings are expected to advance the timetable for a total ban(禁止) of the chemicals.
【1】The scientists have observed the ozone layer ________.
A. since 1980 B. since last winter
C. for about 20 years D. for about one year
【2】The ozone layer in the atmosphere can ________.
A. do a lot of good to human beings in many ways.
B. protect humans from diseases caused by bad weather.
C. do a lot of harm to human beings in the summer-time.
D. protect humans from harmful levels of ultraviolet radiation.
【3】Scientists first found that there was a hole in the ozone layer ________.
A. above Arctic during the winter in the mid-1980s
B. above Antarctica during the winter in the mid-1980s
C. over somewhere in the north of the equator in 1980
D. over the U.S.A in the summertime in the mid-1980s
【4】The damage to the ozone layer was caused by ________.
A. the changeable weather
B. ozone-destroying chemicals
C. chemicals from refrigerators
D. chemicals from air conditioners
