Ⅱ.阅读理解
A
Most people can't wait for spring to arrive.It means flowers and warmer weather，all welcome changes from the dark winter days.Now we know that spring is arriving sooner in the Northern Hemisphere(北半球)than it was in the past，thanks to a study published in Scientific Reports.
For example，Los Angeles may experience spring only a day earlier than it did 10 years ago，but further north，in Seattle or Chicago，spring will arrive four days earlier.If you lived in the Arctic，spring could arrive 16 days earlier than it used to.
To determine how springtime is starting earlier，researchers looked at temperature
records and 743 earlier studies over 86 years.These studies were about various biological indicators of spring，including birds migrating，plants flowering and amphibians(两栖动物)sounding their mating calls.Researchers then studied these data to see if they were occurring earlier.The result showed that not only is spring making itself known sooner but it's warmer，too.
Before you go out in a happy springtime hike，spring arriving sooner isn't so good.The livelihood of migratory birds，for instance，may be concerned.
“The food that birds rely on when they move to the north might not be reliable if the beginning of spring at these higher latitudes(纬度)is expanded by future warming.”said Eric Post.He is a fellow of the John Muir Institute and a polar ecologist.
Animals relying on Arctic sea ice，like polar bears，probably aren't crazy about things warming up sooner，either，because it impacts on their ability to hunt.Spring's early arrival could cause disorder in the delicate balance of various ecosystems—not to mention how soon you'll need to buy allergy medicine.

Throughout history，humanity has existed side­by­side with viruses and bacteria.From the bubonic plague to smallpox，humanity has evolved to resist these bacteria and viruses.However，there are now new ways for them to infect us.
Climate change is melting permafrost(冻土) areas that have been frozen for thousands of years.As the permafrost melts，so too the ancient bacteria and viruses that have been frozen.These ancient bacteria and viruses，which previously lay inactive in the ice，may spring back to life as the earth's climate warms.
In August 2016，a 12­year­old boy in the Arctic Circle died and at least twenty people there were hospitalized after having been infected by anthrax(炭疽)．Experts studied and concluded that over 75 years ago，a reindeer infected with anthrax died and its body was frozen and trapped under a layer of permafrost.It stayed there，with the disease inactive，until a heatwave in the summer of 2016.The heatwave melted the permafrost and exposed the reindeer body，which then released the infectious pathogen(病原体) into the nearby water and soil，and then into the food supply.More than 2，000 reindeer feeding near the body became infected，which then led to a small number of human cases.
While you may think the incident is isolated to that area，the fact that long­inactive viruses and bacteria might wake up soon due to climate change will affect us all.Pathogenic viruses might be preserved in old permafrost layers，including some that have caused global epidemics in the past.
With climate change，who knows what deadly viruses and bacteria hidden beneath permafrost areas are threatening us.Perhaps it is time for everyone to do their part to stop global warming.
【语篇解读】本文讲述了由于全球变暖导致的疫情蔓延，从而呼吁阻止全球变暖。

5．What does the underlined “new ways” refer to?
A．Ancient bacteria and viruses came back to life.
B．Bacteria and viruses have evolved into new types.
C．Bacteria and viruses become more resistant to medicine.
D．Ancient bacteria and viruses remain active in frozen permafrost.
A[词义猜测题。

根据第二段中的“These ancient bacteria and viruses，which previously lay inactive in the ice，may spring back to life as the earth's climate warms.”可知，现在之前被冰封的古细菌和病菌，随着地球气候的变暖会再度活过来，所以new ways是指古细菌和病菌复活，故选A。

]
6．Which is the right order of the case of anthrax in 2016?
①A 12­year­old boy died and many others were infected.
②Over 2，000 reindeer feeding near the body became infected.
③The bacteria went into the nearby water，soil，and then food supply.
④The permafrost melted and the bacteria in the dead reindeer woke up.
A．④③②①B．④②③①
C．①②④③D．①③④②
A[细节理解题。

根据第四段中的“Experts studied and concluded that over 75 years ago，a reindeer infected with anthrax died and its body was frozen and trapped under a layer of permafrost.It stayed there，with the disease inactive，until a heatwave in the summer of 2016.”可知，七十五年前一头鹿感染了炭疽，鹿死了，身体被冰封，病毒休眠，直到2016年的夏季酷热期苏醒。

根据“The heatwave melted the permafrost and exposed the reindeer body，which then released the infectious pathogen(病原体) into the nearby water and soil，and then into the food supply.More than 2，000 reindeer feeding near the body became infected，which then led to a small number of human cases.”可知，这些苏醒的病原体进入到附近的水、土地然后进入食物中，感染了超过2 000头鹿，然后感染了人类，根据第三段中的“In August 2016，a 12­year­old boy in the Arctic Circle died and at least twenty people there were hospitalized after having been infected by anthrax(炭疽)．”可知，在2016年一个十二岁的男孩感染炭疽并死去，并感染了其他人。

所以顺序为④③②①，故选A。

] 7．Why does the writer write this text?
A．To introduce an ancient virus，anthrax.
B．To call on people to stop global warming.
C．To encourage people to study ancient viruses.
D．To warn of the danger of melting permafrost.
B[推理判断题。

根据最后一段中的“Perhaps it is time for everyone to do their part to stop global warming.”作者认为是时候大家一起来阻止全球变暖了，可推断，作者写此文的目的是号召人们阻止全球变暖。

故选B。

]
8．In which section can we most possibly read this text on a website?
A．Geography. B．Environment.
C．Education. D．Medicine.
B[推理判断题。

本文主要是讲全球变暖导致疫情的蔓延，所以属于环境类，故选B。

Ⅲ.阅读七选五
Youngsters usually benefit from having a relationship with someone older and wiser to mentor(指导) them.The mentor might be a teacher，family member or more experienced peer.However，not everyone is suitable to be an influential，positive role model. 1 Here are some common characteristics of good role models.
They are confident.Most people admire those who have much confidence in themselves. 2 So they are able to acknowledge their skills and achievements without becoming arrogant (自大的)．Just as Child Development Specialist Dr.Robyn Silverman suggests，healthy self­confidence shows as pride in who you are and what you've learned throughout your life.
3 Role models show their commitment to a desired goal by their actions and are willing to invest the necessary time and effort to achieve success.They don't give up easily and continue trying when faced with challenges.Their determination to succeed encourages youngsters to follow through and reach the goals they set for themselves.
They are respectful. 4 Young people appreciate being treated with respect and admire those who treat them and others that way.Role models who show selflessness and an equal，non­prejudiced view of those different from them earn the admiration of others.
They are optimistic and creative.Role models inspire others with a positive outlook on life.For example，a community leader faced with a financial setback (挫折) might welcome the opportunity to organize a fund-raising project that pulls everyone together in a constructive manner. 5
A．They are hard-working.
B．They are knowledgeable.
C．Role models show respect for others.
D．Pick someone having the same hobbies and similar qualities as you.
E．Good role models have a healthy appreciation of their accomplishments.
F．Effective role models possess desirable characteristics that make them easy to look up to.
G．Role models tend to see the bright side in difficult situations and can find creative solutions.

Section ⅢReading & Writing
Ⅰ.阅读理解
A
A company in San Francisco，California，has found a way to turn used plastic bottles into women's shoes.
Every day，millions of Americans drink water and other liquids from plastic bottles.More than 60 million of them are thrown away each day.Many of the plastic bottles end up in landfills or are burned with other waste products.
A San Francisco start­up company called Rothy's，however，turns this plastic waste
into environmentally friendly shoes.Roth Martin is the company's co­founder.He explains how they turn plastic into soft material for women's feet.They take the plastic，clean it，and break it down into small pieces.Then they press them through a device that makes soft fibers.Those fibers are then combined together.This is done by a 3D machine.It is designed to reduce waste while making the shoes.The knitted stuff and the inner part of the shoe are then attached to the shoe's outer part，called the sole (鞋底)．This outer sole is also made from environmentally friendly material: responsibly sourced no-carbon rubber.
Rothy's shoes are sold online.They are flat shoes，with either a rounded or pointed toe.They come in different colors and designs.They cost either $125 or $145 per pair，depending on the design.After American actress Gwyneth Paltrow discovered them last year，the demand for the shoes grew.Martin says there is no shortage of material to fill that demand.“We're not going to run out of water bottles any time soon.So we have a limitless supply of material，and I think that is a good sign for our future.”When the environmentally friendly shoes wear out，customers can return them at no cost to a company that uses the recycled materials to make other products.
For now，the shoes are only available to be shipped in the United States.However，the company says it will add international shipping in the near future.

How could we possibly think that keeping animals in cages in unnatural environments—mostly for entertainment purposes—is fair and respectful?
Zoo officials say they are concerned about animals.However，most zoos remain “collections”of interesting “things”rather than protective habitats.Zoos teach people that it is acceptable to keep animals bored，lonely，and far from their natural homes.
Zoos claim to educate people and save endangered species，but visitors leave zoos without having learned anything meaningful about the animals' natural behaviour，intelligence，or beauty.Zoos keep animals in small spaces or cages，and most signs only
mention the species' name，diet，and the natural range.The animals' normal behaviour is seldom noticed because zoos don't usually take care of the animals' natural needs.
The animals are kept together in small spaces，with no privacy and little opportunity for mental and physical exercise.This results in unusual and self­destructive behaviour called zoochosis.A worldwide study of zoos found that zoochosis is common among animals kept in small spaces or cages.Another study showed that elephants spend 22 percent of their time making repeated head movements or biting cage bars，and bears spend 30 percent of their time walking back and forth，a sign of unhappiness and pain.
Furthermore，most animals in zoos are not endangered.Captive breeding(圈养繁殖) of endangered big cats，Asian elephants，and other species has not resulted in their being sent back to the wild.Zoos talk a lot about their captive breeding programmes because they do not want people to worry about a species dying out.In fact，baby animals also attract a lot of paying customers.Haven't we seen enough competitions to name baby animals?
Actually，we will save endangered species only if we save their habitats and put an end to the reasons why people kill them.Instead of supporting zoos，we should support groups that work to protect animals' natural habitats.
【语篇解读】本文介绍了动物园的一些错误做法，指出了不应该把动物圈养在动物园里，而应当通过保护动物的自然生存环境和停止杀害来保护濒危动物。

Ⅱ.读后续写
阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一个完整的短文。

Growing up，my parents and older brothers all smoked.Being a child of the 80s，it was normal for the adults to be smoking inside and during trips in the car.There just wasn't the same awareness of the dangers of second­hand smoke exposure that there is today.
I remember the day when I started smoking.I was 11.I was trying to impress one of the “bad boys” at school.I stole tobacco from my father and rather clumsily rolled a cigarette that I took to school with me.Smoking gave me a sense of autonomy and choice over my own life，and at 11 it was the ultimate act of rebellion.Soon I got addicted to it and was taking cigarettes from dad's packets on a regular basis.I knew he never started counting them until he had less than half a pack left.
After a while I got caught smoking at school.My parents struck a deal with me: if I stopped smoking at school，they would purchase more tobaccos for me to smoke at home.This was perhaps a misguided attempt to keep me out of trouble.I jumped at the idea，and simply got smarter about smoking at school.
I smoked right through my teens and early 20s，spending thousands of dollars on cigarettes，sacrificing food and other necessities to ensure I had cigarettes.
I tried many methods to quit，but each time I would go back to smoking.I have always had a love­hate relationship with cigarettes.On the one hand，they were a friend to me when I had no other，one constant in my life I could rely on.On the other hand，I despised (鄙视) being dependent on something that was going to kill me.
I grew concerned about the effect my smoking would have on my children and I felt guilty putting cigarettes over other things that could have benefited my family.It is with great shame that I admit that I continued smoking even after having a daughter born with cystic fibrosis (囊性纤维化)．My daughter fights every day to breathe — and here I was intentionally causing damage to my lungs.

The turning point for me was an incredibly painful st June a family member aged only 17，died after a long battle with cystic fibrosis.The cruel twist of fate robbed her of the life that she so richly deserved.Smoking for another five weeks after her death，I suddenly felt ashamed of myself and was overwhelmingly sorry for my daughter.I visited a doctor，who suggested me adopting electronic cigarettes as a substitute.I practiced over a couple of weeks and noticed the number of cigarettes decreasing.
I set myself further little goals，such as only taking my e­cigarettes whenever I went.I made a record of every cigarette I had，and the associated triggers for that particular cigarette.The first day I counted 15 cigarettes，approximately half of what I usually smoked.By day 12，I was down to two.I had my last cigarette on July 14.After
20 years as a smoker，I was free from the addiction，finding the smell of cigarettes unbearable.To anyone wanting to quit，all I can say is give your plan a go! You have nothing to lose and everything to gain.。
