Hundreds of feet below the ocean's surface,somewhere between the dark ocean floor and the bright blue shallows,lies the twilight zone.It's a world of the unknown,and many assumed that the lack of light and cold temperatures meant few species could exist there.
    But one scientist has been diving into the inky depths to show there's much more to life there than was first thought.Rocha,a researcher from the California Academy of Sciences,was attracted to twilight zone reefs because of their mystery (神秘). "Every dive we do to those depths leads to a new discovery," he says.To date,he has identified over 300 new species.
    Entering the twilight zone is no easy feat.Recreational diving is capped at 130 feet for safety reasons,but Rocha dives as far as 500 feet.To do this requires deep concentration,intense technical training and a strong dose of bravery.Rocha usually dives in a group with two scientists and one safety officer.They spend hours preparing the kit,ensuring every piece of equipment is functioning well and that they are equipped to deal with underwater emergencies.
    While the twilight zone has been explored by very few people,the effects of human activity are still apparent.One of their first discoveries is that those deeper reefs are really not a shelter for shallow reef organisms.They are almost as impacted as the shallow reefs are.They find plastic waste and fishing gear in some of the deepest reefs and has observed the impact of overfishing and climate change.
    Rocha hopes that his research can help to educate people about the twilight zone and inspire action to protect it. "I don't think it's enough just to do the science.We take many,many photographs…and we bring those stories back up to the surface and we share it with as many people as possible.For the most part,I'd like to let people realize that those creatures are under threat," he says.

  • 1.    Health chiefs are to use artificial intelligence to screen and treat people at risk of hepatitis C (丙型肝炎) under plans to wipe out the life-threatening disease by 2030.
        The National Health Service (NHS) scheme,due to start within weeks in England,aims to identify thousands of patients unaware that they have the virus so that treatment can be given before it is too late.Staff will use AI to comb through patient health records and look for significant risk factors,such as historical blood transfusions (输血) or an HIV diagnosis.Hepatitis C often has no noticeable symptoms until the liver is severely damaged,which means the infected party may not know they are living with a potential killer.It can be cured with modern treatments.
        Anyone identified by the AI software will be invited for a consultation by their doctors and,if necessary,will experience further screening for hepatitis C.Patients who test positive for the virus — which can be caught from contact with the blood of an infected person,such as by sharing a needle — will be offered antiviral medicines after NHS England struck a deal with three drug companies.Professor Graham Foster,the national clinical chairman for NHS England's hepatitis C elimination (消灭) programmes,described the scheme as "a significant step forward" in the fight to eliminate the virus.
        Hepatitis C deaths fell by 35 percent in the five years to 2020,from 482 to 314,according to the latest data from the UK Health Security Agency.The fall in deaths was thanks to earlier detection of the virus and improved access to treatments,health experts said.
        NHS staff will also visit at-risk communities in specially equipped vans (货车),to test for the virus and carry out liver health checks,in a bid to wipe out the virus in England before the 2030 goal set by the World Health Organization.

    (1)What is the purpose of the NHS scheme?

    A.To make the most of artificial intelligence.
    B.To record the blood transfusions in the history.
    C.To diagnose the patients with serious unnoticeable symptoms.
    D.To pick out the potential patients to provide timely treatments.
    (2)What can we infer from Paragraph 3?

    A.NHS scheme can be helpful in removing the hepatitis C virus.
    B.Hepatitis C can be spread through contact with blood of patients.
    C.All the patients have to be re-examined again for the hepatitis C.
    D.Related consulting service will be arranged by the doctor for free.
    (3)Why did Hepatitis C deaths decline in the 5 years to 2020?

    A.Because the related figure was updated on time.
    B.Because the liver healthy check-ups were scheduled.
    C.Because the virus was discovered earlier and better treatments were available.
    D.Because the virus was tested in advance and communities were well-equipped.
    (4)What is the main idea of the passage?

    A.Hepatitis C is a life-threatening disease.
    B.Hepatitis C deaths in the UK have declined.
    C.NHS scheme helps to kill the hepatitis C virus.
    D.AI is a new weapon against deadly hepatitis C.
  • 2.    A water lily painting,Water Lily Pond,by Claude Monet,the French impressionist artist,was sold for more than S80 million on Tuesday,breaking the auction (拍卖) record for himself.Water Lily Pond was part of a four-work collection of water lily paintings that Monet put up for sale during his lifetime.
        The four paintings of Monet's water lily garden were signed and dated by the artist in 1919.One of the other paintings is at the Metropolitan Museum of Art in New York,while another was sold at auction in 1992 for $ 12.1 million and is in a private collection now.The final painting in the series was cut into two before World WarⅡ.
        "After a fierce bidding battle between a number of buyers in the room and on the telephone,the painting finally was sold to a collector for $ 80.4 million,setting a new world record price for the artist at auction," said Olivier Camu,a scholar of impressionist art.
        The last record for a Monet work was set in May when Le Pont du Chemin defer a Argenteuil was sold for $ 41.4 million.The painting sold on Tuesday was bought at a 1971 New York auction for $ 320,000.It has not been exhibited since then.
        Monet's later works had unique characteristics,especially Les Grandes Decorations,another good example,which was bedded in Musee de I'Orangerie in Paris five months after Monet's death in 1926.
        Monet created his water lily garden in Giverny,France.He selected different water lilies in an effort to get as many different colored flowers as possible,specially creating the garden as a base for his paintings.

    (1)According to the passage,Water Lily Pond broke the last record for Monet's paintings by
    A.$ 12 million
    B.$ 39 million
    C.$ 41.4 million
    D.$ 0.32 million
    (2)What can we learn about Water Lily Pond?

    A.It was once auctioned in America.
    B.It was cut into halves before World WarⅡ .
    C.It had been kept in New York for over 40 years.
    D.It was once put in Musee de I'Orangerie.

  • 3.    Two months of the hottest summers on record,the effects of extreme wildfires are being felt acutely throughout the world.In the US alone,over 55 million acres of land have been burned since 2015 due to wildfires.A report in early 2022 by the UN Environment Programme estimated that the number of extreme wildfires experienced globally will increase by 50 percent by 2100,largely as a result of increasing temperatures and widespread drought.
        Wildfires can be deadly,as is seen in a newly released documentary,From Devil's Breath.The film tells the story of a community working together to recover from one of the most devastating wildfires in European history.On June 17,2017,four separate fires broke out in Portugal's rural city Pedrógão Grande among one of the hottest,driest summers on record.Throughout the season,over 1.2 million acres of land were burned across the country.In Pedrógão Grande alone,the fire claimed 66 lives and left a further 253 people injured,making it the deadliest wildfire in Portugal's history.Even several years since the fire,much of the landscape still bears the scars.
        However,despite the devastation,Pedrógão Grande's residents took the filmmakers by surprise. "I thought we might meet a more terrified community after this tragedy," Von Einsiedel said. "What we found was a community coming together to honor those who had lost their lives and stand by each other to heal from this collective trauma,while at the same time working hard to make sure a tragedy of this nature could never happen again."
        Tom Crowther,a local resident,encountered a similar air of recovery. "Despite the devastation of the fires,hope prevailed," he said. "This hope was not only for a better future.People I spoke to were also genuinely motivated by the idea that their restoration of local nature can make a small contribution in the global fight against biodiversity loss and climate change."

    (1)What is the function of Paragraph1?

    A.To state the reasons of wildfires.
    B.To introduce the topic of wildfires.
    C.To show the report of wildfires.
    D.To explain the concept of wildfires.
    (2)What can we learn about the wildfires in Pedrógão Grande?

    A.Wildfires killed 66 people and injured 253 in Portugal.
    B.Wildfires happened only because of the high temperature.
    C.Over 1.2 billion acres of land were burned all over the country.
    D.Many burned areas still don't recover well after the fire.
    (3)Which aspect of the residents in Pedrógão Grande surprised Von Einsiedel?

    A.Their support of each other.
    B.Their concern about this tragedy.
    C.Their hope for a better future.
    D.Their contribution to climate change.
    (4)What is the meaning of the underlined "prevailed" in the last paragraph?
