21、 The chicken-loving dog spent last month guarding the island’s penguin colony, with great success.
A SOUTH-WEST Victorian chicken farmer known as Swampy and his dog Oddball may have found a way to save some of Australia’s endangered wildlife from enemies. After Warrnambool’s once flourishing penguin population was killed in large numbers by foxes and dogs until only 27 remained, Allan Swampy Marsh hatched an effective plan to save the birds. His four sheepdogs had been protecting his chickens against enemies for a decade. He figured they could do the same for the penguins. “The difficulty was trying to convince all the wildlife wallies to think outside the square,” Mr Marsh said. “It’s not an unselfish view of penguins or chicks but the sense of territory (领地) that makes the dogs work, and it is far stronger in these dogs than any other trained breed.”
Oddball’s work as guardian of Middle Island’s colony last month was a success. At the end of the month, 70 pairs of happy feet were counted returning to the island. About 2,000 penguins occupied the island in the 1990s. “Oddy is really protective of the chicks, so to her the penguins were only chicks in dinner suits,” Mr Marsh said. Highly territorial dogs have been bred in Italy to guard livestock for 2,000 years. They manage to keep off trouble makers such as foxes and dogs. The trial’s success has generated interest from overseas. The use of guard animals such as dogs — and even alpacas, which also stop foxes — is now being considered to save other endangered species such as the eastern barred bandicoot.
【1】What had happened to most of Middle Island’s penguins?
A.They had been killed by other animals.
B.They had been scared away by people.
C.They had stopped breeding for no obvious reason.
D.They had been taken to another island for protection.
【2】About how many penguins were on the island when it had the largest number?
A.27. B.70.
C.1990. D.2000.

D.Dogs’ training in protecting animals.
【4】What feature of the dogs is most important in this story?
A.They come from Italy. B.They are very territorial.

【5】The purpose of the last paragraph is to suggest that________.
A.people should think globally but act locally
B.Allan ‘Swampy’ Marsh is a typical Australian
C.it may be possible to use this local idea more widely
D.every environmental problem needs a unique solution
22、Every year, students across the U.K.engage in the annual ritual (仪式) of telling college and university admissions officers why they deserve a seat at the school of their choice.However, this task is filled with anxiety and fear.【1】 This, of course, leads many to ask the question: How should I write an essay about myself for college? Here are tips to keep in mind.
【2】 For example, if all your friends are writing application essays about covid-19, that may be a good reason why you should avoid it.Unless, of course, you’ve had a vivid, life-changing experience that you are burning to share.Admissions counselors say that the best essays help them learn something about the candidate that they would never know from reading the rest of the application.
Keep your individuality in the spotlight.【3】 What sets you apart from others? Tell your extraordinary story but remember not to oversell yourself.Your reader wants to see something personal about you, something that makes you stand out among others.Imagine how many applications the admissions committee reads per day, and think twice before writing some general information that doesn’t show your individuality.
Committees value authenticity.They want to hear your voice.This essay may give you the time and space to explain why a particular achievement means too much to you.But resist the urge to exaggerate: admission counselors read thousands of essays each year.【4】
Sound like yourself.Don’t use words you wouldn’t normally use.Don’t use fancy language you wouldn’t use in real life.Imagine yourself reading this essay out loud to a classroom full of people who have never met you.【5】 Be on the lookout for words and phrases like ‘maybe’ ‘sort of’ ‘I think’ or anything else.
A．They can spot something unreal.
B．This rule works in all the aspects of your life.
C．Writing about oneself can be highly stressful.
D．Keep a confident tone even if you’re not feeling that way.

G．Experts often recommend looking for something unique of your life story.
23、 Believe it or not, dental floss(牙线) has been around for thousands of years. Researchers have discovered dental floss in the ancient teeth of prehistoric(史前的) humans. After all, people have been getting food stuck in their teeth since they began to eat!
In the early 1800s, a dentist advised people to use the dental floss. In 1819, New Orleans (新奥尔良) dentist Levi Spear Parmly wrote a book called A Practical Guide to the Management of the Teeth. In the book, he advised people to floss waxed(含蜡的) silk thread(线).
Although historians believe Parmly was the inventor of modem dental floss, the first patent(专利) for dental floss was presented to Asahel M. Shurtleff in 1874. Shurtleff's company didn’t begin to provide unwaxed silk floss for home use until 1882.
However, dental floss didn't become popular right away. Professional dentistry was still a developing field, and silk thread was expensive. Flossing didn’t become more common until World War II ended. Dr. Charles C. Bass used nylon (尼龙) floss to replace silk floss. Then Today, dental floss is still made of nylon, as well as other types of plastic fibers(纤维).
Some dentists say that we’d better floss at least once each day if we want to keep our teeth clean and healthy. Sadly; studies have shown that only 10 percent to 40 percent of Americans floss every day.
【1】Parmly gave advice to people that they could use ________ to clean teeth.
A.waxed silk thread B.unwaxed silk thread
C.nylon floss D.plastic “floss picks”
【2】Who got the first patent for dental floss?
A.Levi Spear Parmly. B.Asahel M. Shurtleff.
C.Dr. Charles C．Bass. D.Not mentioned.
【3】The underlined word “replace” probably means “________” in English.
A.take the place of B.change the place of
C.help to produce D.give up
【4】After reading the passage, we can know ________.
A.A Practical Guide to the Management of the Teeth is an article
B.there hadn’t been unwaxed silk floss since people use dental floss
C.you need to wrap(包，缠绕) it around your finger when you use “floss picks”
D.some dentists advise us to floss at least once each day
【5】What’s the best title for the passage?
A.Development of Dental Floss B.Famous Dentists in America
C.A Famous Book about Dentistry D.Different Materials of Dental Floss
24、Elizabeth wouldn’t walk or talk as an infant. Angela’s left leg was so enlarged that it hurt to stand. Emma needed a breathing machine just to sleep. Their suffering may take different forms, but their stories share a common thread: Neither they nor their families knew what was actually causing these issues.
Undiagnosed diseases are more common than you might think. Tens of millions of Americans likely suffer from disorders they cannot name. For many, the symptoms are minor. But in some cases, patients come to their doctors with serious problems caused by diseases that challenge medical knowledge.
Those cases are precisely where the Undiagnosed Diseases Network (UDN) steps in. Established in 2008, the UDN’s mission is to provide answers for patients with diseases that doctors are unable to diagnose. Anyone can apply to the program and the UDN works hard to screen every application it receives.
Today, the UDN covers 12 clinical sites around the country, and has evaluated over 1,400 patients. More than 400 of those patients have received a diagnosis thanks to the UDN. In some of these cases, the network is able to match a patient with an already known condition. In others, UDN researchers must work to describe an entirely new disease and enter it into the medical dictionary. The program has added at least 25 entirely new diseases in this way. Additionally, the UDN covers the cost of the tests, meaning patients aren’t burdened with crushing medical debt.
This kind of groundbreaking work helps more than just the patients themselves. Insights from studying rare diseases offer new knowledge about the human body that can benefit all of us. For example, the discovery of statins, a class of drugs commonly recommended today to help regulate high blood pressure, arose from the study of a rare genetic disorder.
“I think they’ve really advanced and changed the whole model for how we approach many of these illnesses,” says Anne Pariser, director of the Office of Rare Diseases Research. She says the UDN’s multidisciplinary approach — bringing different specialists together to talk about challenging cases — has helped advance the field of rare disease research, especially when it comes to genetic diseases.
Living with a disease without a name can be its own kind of suffering. “You grow up feeling like, I’m in this, crazy, all by myself, and no one really understands me,” says Angela Moon, a UDN participant. For patients like her, the UDN offers hope for treatment, but also for finally being seen.
【1】The purpose of the first paragraph is to ________.
A．arouse the readers’ interest in the UDN
B．give a vivid description of rare diseases
C．introduce the background for the UDN’s founding
D．raise a complicated problem that will be solved later
【2】The fourth paragraph mainly talks about ________.
A．the way the UDN is operated nationwide
B．the progress the UDN has made so far
C．the reasons why the UDN is so popular
D．the development stages the UDN has gone through
【3】What can be learned about Angela Moon?
A．She used to live in despair.
B．She failed to identify with others.
C．She is receiving treatment now.
D．There will be a cure for her condition.
【4】What can be inferred about the UDN’s work model?
A．It has helped spread the knowledge of undiagnosed diseases.
B．It prioritizes participants’ privacy over solving medical mysteries.
C．It is specifically designed to deal with challenging genetic diseases.
D．It emphasizes close cooperation between specialists in separate fields.
