It was near New Year 2014，and David Fajgenbaum，who was battling Castleman disease，was rushed to a CT scan in an Arkansas hospital.Tears streamed down his face.He thought about the first patient who'd died under his care and how her brain had bled in a similar way from a stroke（中風(fēng)）.
But he survived.Also，this experience led David to complete " the undertaking" surprising his doctors. "You learn a lot by almost dying，" they said.
It was in 2010 that David got very sick and was hospitalized for five months.He was learning to become a doctor at the University of Pennsylvania in memory of his mother who died of cancer.The examination showed it was idiopathic multi-centric Castleman disease （MCD）.First described in 1954，Castleman presents partly like an autoimmune（自身免疫的） condition and partly like cancer.It doesn't happen very often — there're only around 7，000 new cases each year in the United States，so a very limited number of experts are on it.
In his hospital bed，David felt weak.His organs were failing，and he noticed curious red spots on his skin.He asked doctors what the "blood moles" meant.But they，focused on saving his life，weren't interested in them.Castleman disease struck David four more times over the next three years.Despite it all，he managed to graduate and later founded the Castleman Disease Collaborative Network （CDCN） devoted to fighting Castleman disease.
In late 2013，Castleman struck again，landing David in that Arkansas hospjye.aial.It marked his closest brush with death yet.After this time，David set out to try to save his own life.Examining his medical charts，he zeroed in on an idea that researchers hadn't explored.With considerable effort，he found a drug called Sirolimus might be beneficial to his discase.After consulting with his doctors，he picked up the drug.So far，it's working.David is in recovery and devoting his medical career to saving other patients like him. "I hope my story offers lessons far beyond medicine about what people can do when they're up against a brick wall，" says David.

1．All routes to STEM （science，technology，engineering and mathematics） degrees run through calculus （微積分） classes.Each year，thousands of college students take introductory calculus.But only a small number ultimately complete a STEM degree，and research about why students abandon such degrees suggests that traditional calculus courses are one of the reasons.With scientific understanding and innovation increasingly central to solving 21st-century problems，this loss of talent is something society can ill afford.
Math departments alone are unlikely to solve this dilemma.Several of the promising calculus reforms were spearheaded by professors outside of math departments.STEM faculty are prioritizing cooperation across disciplines to transform math classes to cultivate a diverse generation of STEM researchers and professionals.
This is not uncharted territory.In 2013，life sciences faculty at the University of California，Los Angeles，developed a two-course sequence that covers classic calculus topics，but also emphasizes their application in a biological context.Creating this course，Mathematics for Life Scientists，wasn't easy.The life sciences faculty involved，none of whom had a joint appointment with the math department，said they turned to designing the course themselves after math faculty rejected their request for cooperation.
In Ohio，Wright State University's Engineering departments also revised math offerings.Rather than changing the content of the calculus course，they focused on preparing students for calculus by emphasizing "engineering motivation for math." The approach enhanced opportunities for students with weaker math backgrounds to succeed in engineering and doubled the average graduation rate of engineering students without reducing the average grade of graduates.Math learning is fundamental to all STEM fields，but the opposite also appears to be true.
（1）What problem is mentioned in paragraph 1？
A．Increasing STEM dropout rate.
B．The reform of calculus courses.
C．Shrinking admission to STEM majors.
D．The shaken belief in the role of calculus.
（2）What does "spearheaded" in paragraph 2 probably mean？
A．challenged
B．evaluated
C．cancelled
D．initiated
（3）What do we know about the calculus course reform according to the text？
A．STEM departments made calculus content easier to improve students' grades.
B．Math departments sought cooperation with STEM counterparts to urge reforms.
C．Placing calculus learning in specific STEM contexts is a workable approach.
D．Removing calculus is the key to increasing graduation rate of STEM students.
（4）What does "the opposite" in the last paragraph refer to？
A．The STEM fields may be the foundation of other science subjects.
B．The STEM fields may be central to making math learning effective.
C．Math learning may set barrier for science study in the STEM fields.
D．Math learning may make way for science study in the STEM fields.發(fā)布：2025/1/1 17:30:2組卷：24引用：3難度：0.5 -
2．I once thought that outer beauty is the only factor to become a great person.When I was young，I read many kinds of books，most of which described characters who are handsome or beautiful.So I think that being beautiful is the only way to become a success.
As I grew up，the story of my best friend made me realize that outer beauty was not so important to make a person successful.She is so beautiful a girl that every classmate liked to chat with her，but she was very arrogant（傲慢）.In her opinion，she could get all she wanted because of her beauty，but all of her friends left her one by one!Only then did she come to know the importance of the beauty in a person's heart，which changed her attitude and she made friends again.
Turning on TV，we can see many advertisements，most of which seem to give us a feeling that，physical attractiveness is the most important thing. There seems to be a boom in plastic surgery.It is surprising that more and more people，especially girls and women，try it like the first man-made beauty in China，Hao Lulu.It is a common sense that attractive people can easily find work.Most good-looking guys，usually get higher scores in the job interviews.But what is real beauty？I want to say that is inner beauty because those who have beauty in their soul are really beautiful persons.
As is known，the beauty judged with eyes is temporary，so we should concentrate on inner beauty.And if we make the efforts to make our minds beautiful，we'll live a happier life.
（1）Why did the author want to have a good appearance when she was young？
A．Because she wanted to follow the example of her friend.
B．Because she wanted to be one of the characters in the book.
C．Because she wanted to get higher scores in the job interviews.
D．Because the successful characters in the books she read were attractive.
（2）Why did the writer refer to her friend's story？
A．To show how beautiful her friend was.
B．To show how important outer beauty is.
C．To show the importance of inner beauty.
D．To show how terrible to be a beautiful girl.
（3）What does the underlined sentence in the third paragraph mean？
A．Surgery is becoming more and more popular.
B．More and more people pay attention to outer beauty.
C．More people can afford the price of doing plastic surgery.
D．The living standard has been improved over the past years.
（4）Which of the following covers the passage best？
A．Inner beauty is the real beauty.
B．How do attractive persons become successful？
C．The key factor to find a good job is being attractive.
D．Plastic surgery is the best way to make a person more beautiful.
（5）What do we know from the passage？
A．If you are too beautiful，all your friends will leave you out of envy.
B．If you have a good appearance，you must get higher scores in the job interviews.
C．Without the TV advertisements，there wouldn't have been a boom in plastic surgery.
D．Those who have good appearances should also develop the beauty in their hearts.發(fā)布：2025/1/1 18:0:1組卷：12引用：2難度：0.6 -
