B 篇(限时7分钟)
(2025·山东济南联考)
For some of us，going to the dentist for routine check-ups is a thing of the ordinary．But for many people around the world，especially those in impoverished (贫困的) areas，having dental improvement and their teeth checked simply isn't possible．A Brazilian dentist Felipe Rossi has devoted himself to helping changing that situation．
Growing up in the USA，Felipe Rossi had just obtained the Bachelor of Medicine Degree and was about to start a master's degree in Pediatric Dentistry (儿童口腔学) when a journey to his father's home—Balsabo in Brazil—converted his initial plan．“All locals didn't have access to dental care，and consequently，many of them suffered deformed teeth or even loss of teeth，leading to many people not daring to laugh with mouth open，” Felipe Rossi recalled．“A desire was planted in my heart．That is，to use my skills to bring healthy smiles to people suffering from dental problems．”
With the support of his parents，Felipe formed an NGO (non-government organization) called Porsorriso to give free oral treatments to individuals with low incomes who require cleaning，fillings，crowns，restoration work and more．His team is composed of approximately 30 registered volunteers who go with him to poor towns and villages in Brazil．
Sponsorship is generally provided by two private companies．
Individuals may also make donations through the “Smile Solidarity” program，where they can choose monthly amounts to contribute．
Porsorriso also holds regular fundraisers to afford the cost of providing free dental services around the country．
As noble as its objective is，Felipe admits that Porsorriso is “struggling to survive” because of the huge cost of providing dental work and the constant fundraising events they have to hold to keep the NGO in normal functioning．“Challenging as it is，it did bring healthy teeth as well as renewed confidence to the locals．We will continue this transformative act whatever difficulties we will face，” Felipe said with a strong will．
【语篇解读】　本文是一篇记叙文。文章讲述了巴西牙医Felipe Rossi创建了非政府组织Porsorriso，致力于为贫困地区的低收入人群提供免费的口腔治疗服务。

C 篇(限时7分钟)
(2024·山东济南模拟)
Voices offer lots of information．It turns out that they can even help diagnose illness．The National Institutes of Health is funding a massive research project to collect voice data and develop the AI that could diagnose people based on their speech．
Everything from your vocal cords vibrations (声带振动) to breathing patterns when you speak offers potential information about your health，says Dr．Yael Bensoussan，a leader of the study．“We asked experts: If you close your eyes when a patient comes in，just by listening to their voice，can you have an idea of the diagnosis they have？”Bensoussan says．“And that's where we got all our information．”Someone who speaks low and slowly might have Parkinson's disease．Speaking unclearly is a sign of a stroke．Scientists could even diagnose depression or cancer．
The team will start by collecting the voices of people．“We were really lacking large what we call open source databases，”Bensoussan says．“Every institution has its own database．But it was really important to create these networks to allow researchers from other generations to use this data．”The ultimate goal is an app that could help bridge access to rural or underserved communities，by helping general practitioners refer patients to specialists．To get there，researchers have to start by collecting data，since the AI can only get as good as the database it's learning from．By the end of the four years，they hope to collect about 30，000 voices，with data on other biomarkers—like clinical data and genetic information—to match．
There are a few roadblocks．HIPAA—the law that regulates medical privacy—isn't really clear on whether researchers can share voices．“Let's say you donate your voice to our project，”says Yael Bensoussan．“Who does the voice belong to What are we allowed to do with it What are researchers allowed to do with it Can it be commercialized？”
【语篇解读】　本文是一篇说明文。声音可用于诊断疾病。美国国立卫生研究院正在资助一个大型研究项目以收集声音数据和发展人工智能诊断系统，但这也面临着一些问题。
8．What does Yael Bensoussan mean in paragraph 2？(　　)
A．Voices may help with illness diagnosis．
B．Scientists can rely on AI to detect illness．
C．Disease symptoms can be noted by machines．
D．It's necessary for doctors to listen to patients talking．
√
A　[推理判断题。根据第二段的内容尤其是Yael Bensoussan所说的话“‘...by listening to their voice，can you have an idea of the diagnosis they have？’”和“‘And that's where we got all our information．’”可知，Bensoussan的话意味着声音可用于诊断疾病，故选A。]
9．How will the research be carried out？(　　)
A．By building a base．
B．By collecting data．
C．By connecting communities．
D．By matching clinical information．
√
B　[细节理解题。根据第三段中的“researchers have to start by collecting data，since the AI can only get as good as the database it's learning from”可知，研究人员不得不通过收集数据开展研究，B项“通过收集数据”正确，故选B。]
10．Why is HIPAA mentioned in the last paragraph？(　　)
A．To prove the researchers' idea．
B．To explain the procedures of the study．
C．To imply the problems with the research．
D．To ensure the commercial value of the study．
√
C　[细节理解题。根据对HIPAA的描述“HIPAA...isn't really clear on whether researchers can share voices．”可知，作者提到HIPAA是为了说明前一句“There are a few roadblocks．”，即研究开展过程中的一些障碍，故选C。]
11．Which of the following can be the best title for the text？(　　)
A．An Application of the Voice Study
B．A Data-collecting Approach to Research
C．A Breakthrough in Medical Findings
D．Sound-aided AI Helps with Diagnosis
