Elizabeth wouldn't walk or talk as an infant.Angela's left leg was so enlarged that it hurt to stand.Emma needed a breathing machine just to sleep.Their suffering may take different forms，but their stories share a common thread：Neither they nor their families knew what was actually causing these issues.
Undiagnosed diseases are more common than you might think.Tens of millions of Americans likely suffer from disorders they cannot name.For many，the symptoms are minor.But in some cases，patients come to their doctors with serious problems caused by diseases that challenge medical knowledge.
Those cases are precisely where the Undiagnosed Diseases Network（UDN）steps in.Established in 2008，the UDN's mission is to provide answers for patients with diseases that doctors are unable to diagnose.Anyone can apply to the program and the UDN works hard to screen every application it receives.
Today，the UDN covers 12 clinical sites around the country，and has evaluated over 1，400 patients.More than 400 of those patients have received a diagnosis thanks to the UDN.In some of these cases，the network is able to match a patient with an already known condition.In others，UDN researchers must work to describe an entirely new disease and enter it into the medical dictionary.The program has added at least 25 entirely new diseases in this way.Additionally，the UDN covers the cost of the tests，meaning patients aren't burdened with crushing medical debt.
This kind of groundbreaking work helps more than just the patients themselves.Insights from studying rare diseases offer new knowledge about the human body that can benefit all of us.For example，the discovery of statins，a class of drugs commonly recommended today to help regulate high blood pressure，arose from the study of a rare genetic disorder.
"I think they've really advanced and changed the whole model for how we approach many of these illnesses，" says Anne Pariser，director of the Office of Rare Diseases Research.She says the UDN's multidisciplinary approach - bringing different specialists together to talk about challenging cases -has helped advance the field of rare disease research，especially when it comes to genetic diseases.
Living with a disease without a name can be its own kind of suffering. "You grow up feeling like，I'm in this，crazy，all by myself，and no one really understands me，" says Angela Moon，a UDN participant.For patients like her，the UDN offers hope for treatment，but also for finally being seen.

2．When you encounter animals，do you wonder what they're thinking？Seeing a newborn lamb or a cute puppy might arouse happy emotions（情感）in us，but what are they thinking？Does the look on their face and how they behave indicate how they're feeling-or are they feeling nothing at all？
Humans have a complex range of feelings，but it's hard to tell what's going on inside the heads of animals.Some of us own dogs because they are good companions，are loyal and seem to connect with us.We might even think they love us.Professor Kim Bard，an expert in comparative developmental psychology from the University of Portsmouth，told the BBC："We have a few studies now that actually show scientifically that some dogs will respond when their owner-but not a stranger -pretends to cry."The empathetic ability of cats，however，is harder to work out.
Other non-domesticated（非馴養(yǎng)的）animals might have feelings too.Giraffes and whales，for example，are known to experience sadness when someone in their group dies.It's believed that even tiny creatures like insects might have emotions as well.Research is beginning to show they experience a wide range of feelings.Kim says "they can be optimistic，pessimistic，or frightened，and respond to pain just like any mammal would."
Dr Barbara J King，Emerita Professor of Anthropology at the College of William and Mary，told the BBC："If we understand the profound depths of emotions animals can feel，this should make us question the existence of zoos and slaughterhouses（屠宰場）around the world，and rethink those systems.It does seem all creatures feel emotion，but what is not clear is do they feel the same way as us？"
（1）What's the purpose of raising questions in the first paragraph？
A．To entertain.
B．To inspire.
C．To appeal.
D．To persuade.
（2）What do the underlined words"empathetic ability"in paragraph 2 mean？
A．The ability to respond to others' questions.
B．The ability to understand others' feelings.
C．The ability to stay calm when facing danger.
D．The ability to share work with their owners.
（3）What's the importance of the research，according to Barbara？
A．It may reduce the times of people visiting zoos.
B．It may change the food chain of the whole world.
C．It may cause zoos and slaughterhouses to disappear.
D．It may lead people to reconsider animals' well-being.
（4）How do the researchers sound when talking about the issue？
A．Careful.
B．Certain.
C．Critical.
D．Regretful.發(fā)布：2025/1/1 18:0:1組卷：2引用：6難度：0.5 -
3．Jamil Jan Kochai，the author of 99 Nights in Logar，searched for more than a decade for Susan Lung—the second-grade teacher who had changed his life over 20 years earlier.On Saturday night，the two were finally reunited at one of his book-reading events.
The writer was born in a refugee camp（難民營）for Afghans in Peshawar，Pakistan，and his family moved to California when he was just a year old.At home，they spoke mostly Pashto and some Farsi，so by the time he reached first grade，he was at a total loss because he could hardly speak English.Then came Mrs.Lung，who quickly realized that Kochai was deeply struggling at Alyce Norman Elementary School.
The two got to work，meeting for one-on-one lessons nearly every day after school.At the end of the school year，Kochai won reading-comprehension competitions.
Lung and Kochai lost touch when Kochai's father got a job in another city and the boy moved on，with a new love of reading and writing.When he grew older，Kochai's parents encouraged him to find his former teacher to thank her.But despite his efforts，he failed to track her down.
"I didn't know her first name.She was always just Mrs.Lung to me，so when I called places to ask about her，they couldn't find any records of her，"Kochai said.
Then，while promoting his first novel，he wrote an essay for Literary Hub magazine touching on the transformative impact that Lung had on his life.Lung's doctor happened to read it，and told the now-retired educator about that.
Lung's husband saw a Facebook post about Kochai's reading event on Saturday in Davis，California and suggested he drive his wife there.
"I had no idea they were going to be there，"Kochai said."It was just like a sweet dream.Mrs.Lung was sitting in the front row.She was just the same Mrs.Lung.Just as sweet，kind and warm as ever."
Kochai and Lung hugged，and Kochai finally got the chance to express to her how much he still thought of her and how much she meant to him.
（1）How did Mrs.Lung help Kochai？
A．By dropping by his house regularly.
B．By asking him to read more in class.
C．By spending extra time tutoring him.
D．By saving him out of a refugee camp.
（2）Why did Kochai have difficulty finding Mrs.Lung？
A．There were few records about her.
B．His parents provided little support.
C．He was too young to remember her.
D．He had limited information about her.
（3）How did Kochai feel when seeing Mrs.Lung at his reading event？
A．Surprised and delighted.
B．Shocked and angry.
C．Ashamed and regretful.
D．Proud and grateful.
（4）What is the best title for the text？
A．A Distinguished Guest Showed Up at a Reading Event.
B．A Writer Was Finally Reunited With His Former Teacher.
C．A Famous Teacher Saved a Poor Student's Whole Life.
D．A Book Changed a Celebrity and a Retired Teacher.發(fā)布：2025/1/1 18:0:1組卷：6引用：4難度：0.2
