第二部分阅读理解（共两节，满分40分）
第一节（共15小题；每小题2分，满分30分）
阅读下列短文，从每题所给的A、B、C和D四个选项中选出最佳选项。
A
Your driving record is something that follows you from the day you get your license until the day you hang up your keys.And it's something that can have an impact on different aspects of your life.
It's a good idea to aim to have a clean driving record.It signals to car insurance companies that you're a responsible and safe driver.This pays off for you since it leads to getting better car insurance rates.
But what's considered a clean driving record?If you get any kind of ticket,do you automatically not have a clean driving record anymore?
Here's what you need to know about having a clean driving record:
Your driving record is a public record of your driving history.Remember,from the moment you get your license,you have a driving record.
On your driving record you can find things like:
·Driving license status
·License classifications
·License points
·Traffic accidents
·Moving violations(违反)and fines
·Defensive driving classes taken
So you have a driving record.But what's the distinction between that and a clean driving record?
A clean driving record means your driving history is free of any accidents,moving violations,or points.But don't let this definition scare you off.All insurance companies have different rules and definitions of a clean driving record.Some insurance companies overlook minor moving violations.So if you have a single speeding ticket or some other relatively minor offense that usually doesn't prevent you from having a clean driving record.
21.Why is a clean driving record important?
A.Because it follows you all the time.
B.Because it is a public recording of your driving history.
C.Because it helps you cut down on the cost of car insurance.
D.Because it signals to others that you are responsible and reliable.
22.What can be found on a driving record according to this passage?
A.Driving habits.
B.Driving pattern.
C.License test.
D.License type.
23.What kind of behavior may some insurance companies accept?
A.Always running red lights.
B.Often speeding on highways.
C.Parking illegally once.
D.Driving after drinking.
B
In March2019,When Sara Cook first got a letter in the mail telling her that someone had paid off part of her medical debt,she thought it was fake.“It seemed like you have a long-lost uncle and you just inherited two million dollars,”Cook says.
A remarkable nonprofit called RIP Medical Debt had indeed paid$5,000toward her bills.The former nurse was deeply moved by the gesture.Craig Antico and Jerry Ashton do have good hearts,who have seen how health-related debt has destroyed lives.Since2014,the men estimate they've spent about$20million to pay off personal debts.Antico and Ashton get their money from individuals and charities that support RIP’s mission.
Don't bother contacting RIP for help,however.Antico says they used to let people reach out to them,but it was a disheartening experience because they weren't able to help everyone who applied.Instead,RIP researches potential recipients based on three rules.First,they look for people who make not more than two and a half times the amount established as the federal poverty level.Then they screen for those whose medical debt is equal to5 percent or more of their income.Third,they look to see whether a person is insolvent(破产的).
For the people who do qualify,RIP’s help is life—changing.“After their letter,I realized that my life really doesn't stink(糟糕),”says Cook,“I may never be able to work as a nurse again,but I can sit at the school library
and help kids read or serve up food in the soup kitchen.When people do something out of the kindness of their hearts,sometimes they may wonder whether it really makes a difference.I want people to know that this had a positive impact.”
24.What was Sara Cook's first feeling about the letter?
A.Grateful.
B.Unbelievable.
C.Confused.
D.Lucky.
25.What do we know from the passage?
A.All Cook's medical debt has been paid.
B.Antico and Ashton have paid Cook's bill.
C.Individuals and charities support RIP.
D.The debt has destroyed Cook's life.
26.Who is most likely to get help from RIP?
A.One who is due to pay huge medical fees.
B.One who submits application to RIP in advance.
C.One whose company is profitless during a long period.
D.One whose earnings are around the federal poverty.
27.Why does Sara Cook want to serve in other fields?
A.Because she wants to pay back the money.
B.Because she wants to show her life is not bad.
C.Because she wants to prove kindness makes a difference.
D.Because she can't work as a nurse any more.
C
For much of human history and in many places,girls were considered property,or required to obey their fathers until the day they had to start obeying their husbands.In most of the world that vision of girlhood now seems not merely old-fashioned but unimaginably remote.In field after field girls have caught up with boys. Globally,young women now outnumber(数量超过)young men at university.Girl babies are more wanted than ever before.Even in places,such as China,where the sex-selective abortion of girls has been common,it is becoming less so.Girls are also less likely to be married off in childhood.In1995almost six in ten girls in South Asia were married before reaching18;that has fallen by half.
When societies handle girlhood well,the knock-on effects are astonishing.A girl who finishes secondary school is less likely to become a child bride or a teenage https://www.doczj.com/doc/d415795594.html,cation boosts earning power and widens choices,so she is less likely to be poor or to suffer domestic abuse.She will have fewer children,and invest more
in them.They will be less likely to die in babyhood,or to grow up stunted physically or mentally.She will read to them more and help them with their homework.All this means they will learn more,and earn more as adults.A recent study estimated that,if100%of their girls completing secondary school is ensured,it could lead to a lasting boost to GDP.
Despite the benefits of nurturing girls,some countries have still failed to grasp them.Only one girl in three south of the Sahara finishes her secondary education.The COVID-19pandemic could disturb progress for girls in poor countries,or even reverse it.When Ebola forced west African schools to close in2014,many girls dropped out,never went back and ended up pregnant or as child laborers.UNICEF warns that something similar could happen with COVID-19—but on a larger scale.
28.What's the main idea of the first paragraph?
A.Girls suffer a lot in human history.
B.Girls'situation has improved a lot globally.
C.Girl babies are more welcomed than ever before.
D.Girls do much better than boys in many fields.
29.What can we infer from the passage?
A.There are more young women than young men at university in China.
B.A girl who completes secondary school will have more children.
C.Children of the girls with schooling may end up earning more as adults.
D.Economy of countries is largely determined by the education level of girls.
30.What does the underlined word“stunted”in Paragraph2probably mean?
A.Healthy.
B.Confident.
C.Underdeveloped.
D.Unstable.
31.Why is Ebola mentioned in the last paragraph?
A.To prove COVID-19is more serious than Ebola.
B.To warm that girls may suffer a lot in COVID-19.
C.To appeal to all to pay attention to the poor countries.
D.To stress the importance of controlling the disasters.

Have you ever seen your favourite celebrity talking about a product on social media?These endorsements(名人代言)might not be random,but are actually seen as a vital part of the marketing process.Human desire for status and making friends,combined with our need to belong to a group,makes us easy to be“socially influenced”. Companies often use that desire to have a similar lifestyle to a celebrity to sell or launch a product.So,what do
these endorsements actually do?
Firstly,they can be used to build brand awareness.A social media influencer should have a strong understanding of the platform they operate on,and therefore can create engaging content that not only sticks to the brand image,but sparks their followers'interests in a product they might never have seen before.
Secondly,influencers can improve a company or product's relationship with their customer base.According to a report on customer loyalty,77%of buyers have been brand loyal for more than ten years.This is also true of60% of millennials.A popular celebrity can target key customers and talk or blog about a product,which can create an instant and lasting bond with the consumer.
Lasty,influencers can improve customer buying habits with seemingly“fair opinions”.We are more likely to respond to“peer recommendation”than traditional ads,meaning the fact we see an influencer as a“friend”can make us less likely to be sceptical about what we are seeing.
So,next time you see a celebrity talking about a product,you might want to consider this could be a carefully crafted marketing strategy designed to target your core needs.If you find yourself perusing a product you've seen on social media,you may well have been influenced.
32.What factors make“social influence”so effective?
A.The need for social position and belonging.
B.The need to join a group and be accompanied.
C.The need to have a famous and successful career.
D.The need for famous friends and a good reputation.
33.Why can social influencers make content appealing?
A.Because they are friendly and easy to approach.
B.Because they have a good knowledge of the product.
C.Because they can spark people's interests in what they use.
D.Because they know how to make use of the platform they work on.
34.How do influencers affect our buying habits?
A.By improving the quality of the product.
B.By building a good relationship with us.
C.By giving fair opinions on the product they are selling.
D.By making us convinced of what they talk or blog about.
35.What of the following can be the best title for the text?
A.Do social influencers affect our buying?
B.Are we persuaded into buying products?
C.Do celebrities make a fool of their followers?
D.Are we aware of the designed marketing strategy?

Dear George,
Knowing you are interested in the street-stall economy in our country,I’m writing to share some related information with you.
Recently,in an effort to stimulate domestic demand,our government has allowed people to set up roadside booths or food stalls on streets on a regular basis.The vendors used to be banned to keep the cities tidy and clean, and their return is expected to help increase people’s income and revive the local economy,which was hit hard during he novel coronavirus outbreak.
Personally,street-stall economy creates job opportunities while energizing lonely city streets.I sincerely invite you to experience it by yourself.I’m sure you will fall in love with it too.
Yours,

W:All right,class.Let’s get ready to go.Are there any questions?

M:Well,if it’s that cheap,I think I can learn to like red.
