Ⅰ.阅读理解
A
Marissa Sumathipala，a student at Broad Run High School outside of Washington，D.C.，
was practicing with her recreational figure-skating team when she crashed with another skater.Her
head hit against the ice heavily.Everything went black.
Up to that point ， Sumathipala’s entire life had centred around her sport—her daily
schedule，exercise routine，even her diet.She had hopes of making the 2018 Olympic team.The
fall on the ice would change everything，including her direction.
Sumathipala had a brain injury and it ended her skating career.Symptoms lasted for years.Her
memory felt unclear at times.She’d find herself dizzy ， sick ， or exhausted.Sumathipala
consulted doctors，so many that she “lost count”. But no one had answers.
Sumathipala began to realize that there was so much unknown about the brain.She set out to
find the answers herself，a path that would eventually bring her to Harvard University，where
she’d concentrate on the human brain.Throughout her four years，Sumathipala homed in on
brain science.She worked with the McCarroll Lab at Harvard Medical School，helping develop a
new method for sequencing synapses(神经突序列) in the brain，which are crucial for memory and
learning.Even as an undergraduate，her colleagues were so struck by how mature her thinking
already was about science that she quickly became a trusted and valued member of the lab.
Also，Sumathipala competed with the Harvard Figure Skating Club all four years.She helped
increase its membership and introduced new skaters to the sport she still loves.“I spent a long time
struggling with my identity，”she said.“Growing up I was just a skater and then，when I got
injured，I had to rebuild my identity.Then I was a scientist.Now，I identify as being both a skater
and a scientist.”
Reflecting on her years at Harvard，Sumathipala said one of the things she’s most grateful
for is seeing how things have come full circle for her.

You may never know why the email will arrive and reasons offered for your rejection might be
the real ones—or not.Bosses have always spied on their employees，then judged them.Now the
rise of the online self means the employer’s eye can travel still farther.
Even before the pandemic，research found that 28% of large companies had turned down
applicants after carrying out such checks.And it is becoming more popular: Reed Screening，a
large agency，was asked to run over a third more social-media checks in December this year than a
year earlier.This month the government gave the practice approval when the Department for
Education said schools and colleges “should consider carrying out an online search as part of
their due diligence(尽职调查)”．
The way screening works is simple: Any“problematic”behaviours will be marked with a red
flag.There are laws governing such online screening.David Erdos ， head of the Centre for
Intellectual Property and Information Law，says that companies are supposed to warn candidates
before screening their social media and tell them that they have the right to hold back
permission.Some companies follow these rules，but others may not.As for the right to refuse，it is
hardly practicable.“Who on earth is...going to be that person who says ， ‘ Hang on a
minute.I’m not happy about that？’”asks Mr Erdos.“That itself is likely to be a red flag.”
All agree that the spread of online screening is alarming，as it is so unforgiving.People may
be unable ever to be free of their online past，says Mr Erdos.As indeed some footballers，recently
punished for comments made almost a decade ago when they were but teenagers，have found to
their cost.
Those within the industry think laws should be tightened，with punishment for illegal act.In
the meantime，being very careful is advisable.In talks to university students，Mr Erdos warns
them what companies will do to their social media when they apply for jobs.“They are universally
terrified，”he says.And rightly.
5．What can we know about online screening from paragraph 2?A．It is turned down by large companies.
B．It boosts the development of education.
C．It is becoming increasingly acceptable.
D．It highlights the wisdom of employers.
6．What do applicants tend to do with online screening?
A．They reject the red flags.
B．They have to submit to it.
C．They will charge the company.
D．They postpone carrying it out.
7．What is Mr Erdos’ opinion on posting comments online?
A．Companies are tolerant of it.
B．Its influence is hard to erase.
C．It should be under strict laws.
D．University students are free to do it.
8．What could be a suitable title for the text?
A．Big Employer Is Watching You
B．Fix Your Eyes on Online Screening
C．Social-media Checks Are Around the Corner
D．Checks Online Are to Blame for Unemployment
