21、Most teenagers are still trying to find their passion and purpose in life. However, not Gitanjali Rao. The 15-year-old sophomore at STEM School Highlands Ranch has been coming up with innovative solutions lo worldwide problems since she was ten. It is, therefore, not surprising that the youngster was selected from 5,000 equally impressive nominees—aged 8 to 16—for TIME Magazine’s first-ever “Kid of the Year.”
The young girl, who knew she wanted to bring change and positivity to her community since 3rd grade, was just ten years old when she heard about the lead-tainted (含铅的) water in Flint, Michigan, in 2015. After spending two months researching how the area’s drinking water became polluted, Rao began designing a device called Tethys, which attaches to a cellphone and informs the resident via an APP if their drinking water contains traces of the harmful metal. The prototype (模型) earned her the Young Scientist Challenge Award in 2017. A start-up entrepreneur is working with scientists and medical professionals to test Tethys’ potential and hopes the device will be ready for commercial use by 2022.
In 2019, Rao took on another social issue—opioid addiction. The app she designed won the Pillar Prize at the Innovation Student Challenge, which helps to catch drug addiction in young adults before it’s too late. Rao said. “I wanted to come up with a way to diagnose such addiction at an early stage so you can take action earlier.”
More recently, the teenager has created another inspiring app. “I stared to hard-code (编写硬编码) in some words that could be considered bullying, and then the computer search engine took those words and identified words that are similar. You type in a word or phrase, and it’s able to pick it up if it’s bullying, and it gives you the option to edit it or send it the way it is.” Rao told editor Angelina in an interview. “The goal is not to punish. Instead, it gives you the chance to rethink what you’re saying so that you know what to do next time around.”

22、Deep in a forest of France’s Burgundy region, a group of enthusiasts have been building a castle with tools and methods from the late 13th century since 1995. Some of those working here are very skilled heritage people, and others are history lovers. But all of them share a deep respect for nature and a desire to return to simpler times.
The idea to build the castle was born in 1995 among three residents of the region. One of them, Maryline Martin, owns a nearby 17th-century house and is involved in work to restore different castles in the area.
“We thought that it would be amazing to imitate (模仿) how people did things in the past,” Martin tells public radio station France Culture. “We decided to use other ancient castles in this area as examples and get inspiration from descriptions in old books.”
On the construction site, the workers are all dressed in ancient clothing. The smell of fire is coming from a nearby blacksmith’s shop, where 20-year-old Matisse Lacroix is burning a piece of iron in a stove to make tools needed to build the castle.
“The temperature in the stove is around 1100℃, so the iron can be softened to make these nails,” Lacroix explains to a group of fourth-graders, who are watching him bending and shaping the iron into nails.
“Part of the project’s mission is to rediscover and pass along skills and knowledge from the past,” Martin tells reporters. “That learning aspect of the project is one reason why its construction is taking so long.”
Initially, the project was funded by European Union. Now it is financed through more than 300,000 visitors a year who pay between 12 and 15 euros each. The income is more than enough to cover the construction costs and payments for the 100 staff members.
As for the project’s future, Martin says it could take 10, 15, or even 20 more years to build. “But we’re OK with that. It’s not about finishing the project. It’s about the things we learn and discover while building,” he says. “I believe the way we’re working here is more sustainable. The future is low tech.”
【1】Which of the following best describes the castle-builders?
A.Famous historians.
B.Enthusiastic conservationists.
C.Housing developers.
D.Professional heritage researchers.
【2】What is the third paragraph mainly about?
A.Maryline Martin’s background.
B.The project’s influence.
C.The inspirations for the project.
D.The history of the castle.
【3】Why has it taken so long to build the castle?
A.The owners don’t have enough money.
B.The workers don’t have proper equipment.
C.The French authorities fail to provide timely support.
D.The participants want to explore the ancient building skills.
【4】What is Maryline Martin’s attitude to high-tech?
A.Skeptical.
B.Unclear.
C.Approving.
D.Objective.
23、Women who own cats are more likely to have mental health problems and kill themselves because they can be infected by a common parasite(寄生虫) that can be caught from cat litter(猫砂), a study has found.
Researchers found women infected with the Toxoplasma gondii (T. gondii) parasite(刚地弓形虫), which is spread through contact with cat waste or eating undercooked meat or unwashed vegetables, are at increased risk of attempting suicide.
The study involved more than 45,000 women in Denmark. About a third of the world's population is infected with the parasite, which hides in cells in the brain and muscles, often without producing symptoms.
The infection, which is called toxoplasmosis(弓形虫病), has been linked to mental illness, such as schizophrenia(精神分裂症), and changes in behavior.
The study's senior author Doctor Teodor Postolache, an associate professor of psychiatry(精神病学) at the University of Maryland School of Medicine in the United States, said, "We can't say with certainty that T. gondii caused the women to try to kill themselves, but we did find a predictive association between the infection and suicide attempts later in life that deserves additional studies."
Doctor Albert Reece, vice president of medical affairs at the University of Maryland, said, "T. gondii infection is a major public health problem around the world, and many people don't realize they're infected. "
Dr Postolache is a leading expert on suicide neuroimmunology(神经免疫学). Suicide is a critically important mental health issue. About one million people commit suicide and another 10 million attempt suicide worldwide each year. We hope that this type of research will one day help us find ways to save many lives that now end too early in suicide."
Dr. Postolache's research team at the University of Maryland was the first to report a connection between T. gondii and suicidal behavior in 2009. He is cooperating with researchers in Denmark, Germany and Sweden to confirm and investigate the way leading to this association.
The T. gondii parasite thrives in the intestines(肠) of cats, and it is spread through their waste. All warm-blooded animals can become infected through contact with it. Humans can become infected by changing their infected cats' litter boxes, eating unwashed vegetables, drinking water from a polluted source, or by eating undercooked or raw meat.
Not washing kitchen knives after preparing raw meat before handling another food item also can lead to infection. Pregnant women can pass the parasite directly to their unborn babies and are advised not to change cat litter boxes to avoid possible infection.
Babies don't produce antibodies to T. gondii for three months after they are born, so the antibodies present in their blood represented infection in the mothers. The scientists studied Danish health patients to determine if any of these women later attempted suicide, including cases of violent suicide attempts which may have involved guns, sharp instruments and jumping from high places.
The study found that women infected with T. gondii were one and a half times more likely to attempt suicide compared to those who were not infected, and the risk seemed to rise with increasing levels of the T. gondii antibodies.
Dr Postolache noted limitations to the study, such as the inability to determine the cause of the suicidal behavior.
The findings were published online in the Archives of General Psychiatry.
【1】The common way which is less likely to be infected with the disease is ________.
A. to eat unwashed meat or undercooked vegetables
B. to clean a place where a cat once lived for a time
C. to pass the infection to her unborn baby during a woman's pregnancy
D. to reuse kitchen tools which have been used to cut raw meat
【2】What is the consequence if a woman is infected with the parasite in the passage?

A. Women have a higher risk to be infected by the parasite than men.
B. The result of the research may help the scientists to find ways to stop suicide in advance.
C. The scientists will continue their research into the possible connection.
D. The risk of being infected seems to rise with the decreasing levels of the antibodies.
【4】Which of the following statements would probably be the best title of the passage?
A. Why are women more likely to commit suicide?
B. Women should keep away from cats
C. Ways found to deal with women's mental problems
D. Are women who own cats at a suicide risk?
24、 Every day, we have messages to give people through Post-it Notes. They have a special glue on the edge(边缘)of the paper. They are sticky so that you can leave them anywhere and they won’t fall off. You can reuse the notes because the special glue on the back doesn’t wear off easily.
Who invented Post-it Notes? Art Fry was a scientist who worked for the famous 3M Company. He needed a bookmark that stayed in place but didn’t tear(撕)the page when he wanted to remove it. So he took some of the weak glue a friend made and put it on the back of a yellow piece of paper. Then he wrote a report to his boss and put the yellow sticky paper on the top page. His boss took off the note, wrote an answer, stuck the paper back on, and sent it back. This was the beginning of Post-it Notes. It was a new and creative way to communicate.
Today, Post-it Notes are one of the most popular office products. Everyone uses them for many different purposes. One man used one to write a marriage proposal(求婚)and put it on his girlfriend’s front door. She wrote her answer and put the note back on his door. One mother put a note on the back of her son’s car before he left on a long trip. When he arrived, he found the note. After 3,000 miles, it was still on the car. One university student was waiting in the bus station and started to feel sleepy. She didn’t want to miss her bus so she put Post-it Notes all over herself. The notes asked people to wake her up in time for her bus. She did fall asleep but her plan worked. Someone saw the notes and woke her up.
There are Post-it Notes to please everyone’s tastes. You can buy Post-it Notes in fifty different colors, twenty-seven different sizes, and fifty-six different shapes. More than 400 Post-it products are sold in more than 100 countries around the world. Art Fry should be proud of his invention.
【1】What do we know about Post-it Notes?

26、Directions: Read the following three passages. Summarize the main idea and the main point(s)of the passage in no more than 60 words. Use your own words as far as possible.
Natural perfume or artificial perfume?
The use of perfume dates back to earliest times. The ancient Egyptians perfumed the bricks used to build their houses and temples, and wore perfumed fat in their hair.
These days, consumer demand for perfumed products is intense. In the home, from washing-up liquid to paper tissues, soap to shoe polish, fragrance is the common ingredient. Artificial leather is perfumed to make it smell like the real thing, and in Japan, some companies spray perfume through building’s air-conditioning system at key times of the working day.
To meet the demands of the perfume industry, scientific developments have made the companies use substitutes for some natural ingredients. Scientists have also discovered that natural and artificial materials are highly complementary and are acceptable to the consumer. Even the most expensive perfumes are in fact compounds of both natural and artificial ingredients. The French perfume manufacturers were among the first to blend artificial compound when they made the famous perfume Chanel No. 5 in 1923.
Producing natural oils is very expensive. For example, 1000 kilos of jasmine flowers make just one kilo of extract. Using artificial fragrance has reduced the costs of manufacture overall, although the chemical operations involved can be very time-consuming and costly-sixteen or seventeen chemical separations may be needed to produce the right result.
Nevertheless, the use of complex chemical to reproduce fragrance is likely to increase, as the artificial ingredients as well as natural oils gives perfume manufacturers more control over the production process, which is why many classic perfumes owe their characteristic top notes to fruits of science not nature.
