If doctors want to test you for something, they’ll usually take a blood or urine sample (尿样). But wouldn’t it be much more convenient if they just asked you to breathe through a special instrument?

In fact, your breath can say a lot about you. In traditional Chinese medicine, doctors draw a conclusion about the health state of a patient based on the smell of his or her breath; trained dogs and rats can identify the smells of the breaths of people suffering from certain cancers; traffic police also monitor drivers’ alcohol consumption by testing their breaths.

Just like blood and urine, your breath contains lots of “ metabolites ” --- the waste chemicals that the body produces, which vary from person to person. They are like personal health fingerprints, which is why scientists sometimes call them “ breath prints”, according to Science Daily.

Compared to blood or urine testing, breath testing takes only seconds instead of hours, and it requires neither a needle nor a container to hold the body fluids (体液). This means the test can be taken frequently to better detect early signs of diseases and monitor the progress of a medical treatment.

On the other hand, as an identifier, you might think that breaths are not as reliable as fingerprints since they might change based on what you eat. However, researchers in Zurich, Switzerland mapped 11 healthy volunteers’ chemical patterns by having them breathe through a special instrument, and they found that each pattern was unique and the patterns didn’t change much throughout the day, reported BBC.

“Our goal is to develop breath analysis to the point where it becomes competitive with the established analysis of blood and urine,” said Malcolm Kohler, professor at the University Hospital Zurich.

If some parts of a body are very sick or damaged, then doctors might need to remove them. Another way doctors can help is to grow new tissue to replace what is sick or damaged. This is called regenerative medicine (再生医学).

Regenerative medicine sounds like something from a science fiction movie but it is not a new idea. Inside our bones, we have something called ‘marrow’, which makes our blood and keeps us healthy. Doctors have been giving sick people the bone marrow from other healthy people for the last 30 or 40 years, and this is a kind of regenerative medicine.

Newer developments in regenerative medicine include growing new skin in a laboratory and using it to help people who have been hurt in fires or accidents. Another example of regenerative medicine is a technique developed from studying frogs and mice. When cells are old, like in adults, they can’t change what they do in our bodies. For example, a skin cell can’t change into an eye cell. But when cells are very young, they can become any cell type. These young cells are called stem cells, and doctors can use them to grow any type of tissue, such as skin, heart or eye. John Gurdon and Shinya Yamanaka won the 2012 Nobel Prize for their studies in this area.

Professor Fiona Watt, from the Centre of Regenerative Medicine at King’s College, London, believes that regenerative medicine is so exciting because many different kinds of experts need to work together. 3D printers may be used to print new bones by experts, who need to work closely with university scientists and the surgeons who do the operations in hospitals.

We can not yet grow new arms or legs for people, but the science fiction dream of regenerative medicine may be closer than we think. Perhaps in the future, doctors will be able to grow whole new bodies for us.

1.What’s the main idea of the passage?

A. How to help very sick or damaged people.

B. Regenerative medicine and science fiction.

C. We can grow our new bodies in the future.

D. Regenerative medicine and its development.

2.Which of the following is right according to this passage?

A. Marrow can help grow new bones.

B. Stem cell can be used to grow any type of tissue.

C. Surgeons now use 3D printers to print new bones.

D. Regenerative medicine is a new science in medicine.

3.What’s the writer’s attitude to the development in regenerative medicine?

A. Pessimistic.　　 B. Optimistic.

C. Doubtful.　　 D. Indifferent.

Chinese scientists have found a new way to use cells found in human urine （尿液）that could aid in the treatment of a range of nerve disorders.That is a new technique for reprogramming cells in human urine into nerve progenitor cells  that can grow into multi-functional nerve and brain cells.

The technique is expected to be used in the study and treatment of nerve disorders such as Parkinson's disease, Alzheimer's disease and other nerve disorders.

Pei Duanqing, a professor at Guangzhou Institutes of Biomedicine and Health, Chinese Academy of Sciences, said his research team has combined an episomal system to deliver reprogramming factors with a chemically defined culture medium to reprogram kidney epithelial(肾表皮) cells in urine into NPCs.

These NPCs, normally only found in the human brain, were later proven to be transgene-free and self-renewing, he said.

"These nerve and brain cells can survive for up to one month when transplanted into the brain of a newborn rat," said Pei. "My team is working hard to understand why our experimental condition allowed the urine cells to become NPCs, because we want to improve the technique and make it more efficient".

Scientists have long searched to treat and study neural disorders by obtaining and transplanting neural stem cells. However, the previous method of getting and using cells from either fetal (胎儿)or adult human tissue remains challenging due to ethical concerns and immune system rejections, he said.

Pei hopes the discovery will be used to generate NPCs from patients with nerve disorders such as Parkinson's disease. "These NPCs from patients may help us discover new drugs for these diseases."

"It is a remarkable advance in the stem cell field. The results and methods obtained from this study will be of great value and significance to the field, " said Fred Gage,a professor with the Salk Institute for Biological Studies.

1.What is the passage mainly about?

A. NPCs are beneficial in treating human diseases.

B. Chinese scientists succeeded in making NPCs from human urine.

C. Chinese scientists have found cures for all diseases.

D. A new technique was used to study the use of human urine

2.Pei and his tean try their best to work hard in order to________.

A. make more contributions to medical study

B. discover another new technique

C. make the technique more perfect

D. treat more patients suffering from bad diseases

3.What is the challenge of making NPCs in the previous method?

A. The ethical comcerns and immune system refusal

B. The difificulties in getting cells from human.

C. The under-developed techniques in medical science.

D. The lack of financial support from the government.

4.From the last paragraph we can infer________.

A. the new technique will be developed in science

B. the results and methods will be applied to treating cancers

C. the study will give a major push to the stem cell field

D. the mew technique will bring great profis

A walk through the galleries of Quebec's Montreal Museum of Fine Arts (MMFA) places individuals face-to-face with some 43,000 artworks ranging from Chinese ceramics (陶瓷制品) to Inuit sculpture.

While the visiting is an incredible cultural experience, a group of local physicians will soon be able to prescribe(开处方) museum visits as treatment for some illnesses.

Hélène Boyer, vice president of a Montreal-based medical association, explains that museum visits have been shown to increase levels of serotonin, a neurotransmitter (神经传导物质) known as the "happy chemical" which helps to lift mood.

According to Boyer, the small increase in hormones(荷尔蒙)associated with enjoying an afternoon of art is similar to that offered by exercise, making museum prescriptions ideal for the elderly experiencing pain that prevents them from regularly joining in physical activity.

The museum visits are designed to improve traditional methods. As Bondil notes, spending time in a peaceful environment can provide a welcome distraction. "What is most important is this experience can help them escape from their own pain," she says. "When you enter the museum, you escape from the speed of our daily life."

"I am convinced that in the 21st century, culture will be what physical activity was for health in the 20th century," said Bondil. " Some people would do well to recall that just in the 19th century, sports were believed to do harm to the body. Just as doctors now prescribe exercise, they will be able to prescribe a visit to the MMFA."

1.What does Hélène Boyer think of museum visits?

A.They can cheer people up. B.They can reduce physical activity.

C.They can slow down our life pace. D.They can increase levels of art appreciation.

2.How do museum visits affect people?

A.Stop them concentrating on pain.

B.Stop them focusing on traditional methods.

C.Encourage them not to be absent-minded.

D.Encourage them to slow their steps while walking.

3.What does the last paragraph suggest?

A.Physical activities were popular in the 19th century.

B.Sports are considered to be harmful to the body.

C.Ideas of treating illnesses are changing over time.

D.Doctors prescribe museum visits regularly now.

4.What is the main idea of the text?

A.Museum visits are ideal for the elderly. B.Happy chemical helps to lift mood.

C.Peaceful environment helps escape pain. D.Cultural activities will promote health

Chinese researchers have developed a robot designed to help doctors treat the new coronavirus and other highly infectious diseases. The machine has a long robotic arm attached to a base with wheels. It can perform some of the same medical examination tasks as doctors. For example, the device can perform ultrasounds (超声波扫描检查), collect fluid samples from a person’s mouth and listen to sounds made by a patient’s organs. Cameras record the robot’s activities, which are controlled remotely so doctors can avoid coming in close contact with infected patients. Doctors and other medical workers can operate the machine in another place.

The robot’s main designer Zheng Gangtie, an engineer and professor at China’s Tsinghua University, told Reuters news agency that he got the idea for the device when his medical friend told him that one of the biggest problems in dealing with COVID-19 was that healthcare workers treating patients were getting infected themselves. Zheng said he wanted to do something to help this situation. So the engineer gathered a team and went to work on the robotic device.

Zheng said the devices use the same technology that is used for space equipment, including moon explorers. The new robot is almost completely automated. It can even disinfect itself after performing actions involving patient contact.

However, Zheng said he had heard from some doctors that it would be better not to build such robots to be fully automatic. This is because many patients still desire a personal presence to help calm them during treatment.

The team currently has two robots and both have been tested by doctors at hospitals in Beijing. One machine was taken to Wuhan’s Union Hospital, where doctors there got trained to use it. The plan is to use the robot to help treat coronavirus patients, along with assistance from nurses and other hospital workers.

Zheng would like to build more of the robots, but says money from the university has run out. Each robot costs about $72,000 to make. He says he does not plan to commercialize the design, but hopes that a company can begin that process.

1.What do we know about the newly-invented robot?

A.It is used for space exploration.

B.It completely operates on its own.

C.It carries out complicated surgical treatments.

D.It protects doctors from risky contact with patients.

2.Which of the following may accelerate the development of the machine?

A.Assistance of AI. B.Financial support.

C.Community help. D.Professional advice.

3.What can we infer from the last three paragraphs?

A.The device may not be welcomed by all patients.

B.The device has been widely used to treat patients.

C.Zheng has received further funds from companies.

D.Zheng continued the production for official support.

4.What is the best title for the passage?

A.Promising Future for the Robot

B.Novel Device to Cure Coronavirus

C.New Assistant to Fight Coronavirus

D.Helpful Design to Save the Patients

It took multiple weddings for Christine Law to realize what she needed to do. In the summer of 2014, her schedule was packed with friends’ marriage celebrations - flower-filled occasions that got her thinking, “Where do all the flowers go after the party？” More often than not, they were thrown away. Law was confident she could find a better use for them.

By August, she had a plan:convince couples and companies hosting events to donate their flowers, which she would pick up and deliver within 48 hours to seniors across the city. She wanted to bring beauty into the lives of the elderly. She drew on her experience through being a volunteer in non­profit institutions in order to set up her own organization, which she called Floranthropie. Not having enough bouquets (花束) for all 150 people of a health center, Law asked the staff to provide a list of patients who needed cheering up most. “The first woman I approached thought it was a mistake, and that the flowers couldn’t possibly be for her,” says Law. “I said they were a gift, and we talked for a half hour.

In addition to health centers, Floranthropie focuses on community groups devoted to the elderly. Laëtitia Thélème is a volunteer for Les Petits Fières, an organization that aims to help the elderly who don’t have a support system. The group receives a dozen or so bouquets from Floranthropie monthly, and then redistributes them. “Our motto is ‘flowers before bread’,” says Thélème. “We don’t focus on primary care, but rather on nourishing (滋养) the spirit. Floranthropie helps us do that. It’s amazing what a big difference a small bouquet can make.”

In the beginning, most of Floranthropie’s donations came through word of mouth. These days, Law receives messages from strangers via her organization’s Facebook page and has connected with corporations and flower wholesalers. Law hopes to expand Floranthropie nationally, but at this point is happy to be able to oversee each delivery personally.

1.What made Christine Law set up Floranthropie?

A.The warm atmosphere of weddings. B.The loneliness of seniors.

C.The persuasion of other friends. D.The waste of flowers.

2.How did the woman feel about Christine Law’s flowers?

A.She was moved. B.She was surprised.

C.She was worried. D.She was excited.

3.What can we infer about Floranthropie from Laëtitia Thélème’s words?

A.It should focus on primary care.

B.It is doing something of great importance.

C.It is benefiting more than the elderly.

D.It should cooperate with more non­profit institutions.

4.What is the best title for the text?

A.Volunteer Your Time B.Don’t Throw Flowers Away

C.Brighten Seniors’ Lives with Flowers D.Special Delivery Makes Your Day

When she first started learning about the climate change from one of her elders, Fawn Sharp was invited on a helicopter flight over the the Olympic Mountains to survey the Mount Anderson glacier. But the glacier was gone, melted by the warming climate. Sharp had a deep sense of loss when she discovered the glacier wasn't there anymore.

Loss is a growing issue for people working and living on the front lines of climate change. And that gave Jennifer Wren Atkinson, a full-time lecturer at the university of Washionton Bothell, US, an idea for a class.

This term, she taught students on the Bothell campus about the emotional burdens of environmental studies. She used the experiences of Native American tribes(部落), scientists and activists, and asked her 24 students to face the reality that there is no easy fix--that “this is such an intractable problem that they're going to be dealing with it for the rest of their lives.”

Student Cody Dillon used to be a climate science skeptic(怀疑论者)， Then he did his own reading and research，and changed his mind.

Dillon wasn't going into environmental work- he was a computer-science major. Yet, the potential for a worldwide environmental catastrophe seemed so real to him five years ago that he quit his job and became a full-time volunteer for an environmental group that worked on restoration projects.

Six months into the work he decided that Atkinson’s class was just what he was looking for--a place where he could discuss his concerns about a changing climate.

Atkinson said she hopes the class helped her students prepare themselves for the amount of environmental loss that will happen over their lifetimes .

“We are already changing the planet--so many species are going to be lost, displaced or massively impacted, "she said, “The future isn't going to be what they imagined.”

1.Why did the author mention the case of Fawn Sharp?

A.To lay a basis for Fawn Sharp’s further research.

B.To prove Fawn Sharp's work is similar to Atkinson's.

C.To lead into the issue of loss caused by climate change.

D.To show scientists’ concern about the Mount Anderson glacier.

2.What's the main purpose of Atkinson’s class?

A.To explore how different people deal with climate change.

B.To get students more concemed about the environmental Issue.

C.To find solutions to the environmental issue of Olympic Mountains.

D.To teach students how to conduct research about environment.

3.Which of the following best explains "intractable" underlined in Paragraph Three?

A.Simple. B.Difficult.

C.Common. D.Interesting.

4.How did Atkinsons class influence Dillon?

A.It made him work as a part-time volunteer for restoration Projects.

B.It made him realize a planet-wide climate disaster would happen.

C.It encouraged him to be more involved in environmental protection.

D.It discouraged him from protecting the environment.
