Tropical rainforests are disappearing at an alarming rate,and according to a new report by Rainforest Foundation Norway,humans are to blame.The world's dependence on coal,farming,soy,palm oil and mining has resulted in two-thirds of Earth's tropical rainforests being completely destroyed,and the remaining ecosystems being put closer to a tipping point (臨界點).
   Tropical rainforests once covered 14.5 million square kilometers of Earth's surface,but now,just one-third of that remains undamaged.Of the original area tropical rainforests once occupied,34% is completely gone and 30% is suffering from degradation.All that remains is roughly 9.5 million square kilometers,and 45% of that is in a degraded (惡化的) state,the report says.
   Researchers blame human consumption for the loss.While agriculture has always been a driving factor of rainforest loss,the report said that energy consumption,international trade and the production of soy and palm oil,logging and mining have been the largest threats over the past century.A significant number of U.S.products rely on resources from tropical rainforests.The country heavily relies on palm oil,rubber and cocoa,all of which come from forests around the world.Oftentimes,these resources are harvested from illegally deforested lands.
   Tropical rainforests are home to more than half of the Earth's biodiversity and have more carbon in living organisms than any other ecosystem.Along with supporting significant animal life,tropical rainforests are also essential to slowing down global warming. "These highly specialized ecosystems are suffering from constant abuse,through our bottomless appetite for land and resources," said Anders Krogh,who authored the report. "We expect that upcoming UN climate and biodiversity summits provide specific targets and measures to protect tropical rainforests."
   The researchers also believe that the loss of tropical rainforests puts the whole world at risk of future pandemics. "Massive deforestation (毀林) is violating nature's natural virus protection systems." Krogh said. "The consequences of COVID-19 should bring rainforest protection to the top of the agenda of all policy makers and world leaders concerned about preventing the outbreak of new pandemics."

  • 1.    Reading is a complex and crucial skill that impacts the youth's ability to perform as students.Therefore,it's important to develop reading skills during childhood.A team of researchers focused on the effect of whole-body learning in instruction,known as embodied learning.
        The research included 149 children,aged 5 to 6,who had just started school.They were divided into three groups:one that stood up and used their whole bodies to shape letter sounds;a seated group that shaped letter sounds with their hands and arms;and a control group that received traditional,seated instruction during which they wrote letters by hand.
        "Our research showed that children who used their whole bodies to shape the sounds of letters became twice as proficient at letter sounds that are more difficult to learn as those who received traditional instruction" says PhD student Linn Damsgaard of UCPH's Department of Nutrition,Exercise and Sports.
        With regard to difficult letter sounds,she adds, "There are many difficult letter sounds in Danish.These sounds are particularly important because once children become skilled at them,they will be better readers.
        Associate professor Jacob Wienecke,who led the study,explains,the primary goal is to learn more about which methods can be used to give beginner readers a good start.The idea is that if,through play and movement,we can learn where their strengths truly lie,we'll create a form of learning that combines reading with play,and that's truly positive."
        Previously,the researchers showed that the children felt more motivated by teaching methods which included physical movement.Jacob Wienecke hopes this will provide an opportunity to inspire teachers and school managers to prioritize movement across subjects.
        The study also investigated whether a direct effect of embodied learning could be found on children's reading of words.This was not possible,which might be due to the fact that the children were at such an early stage of their literacy development that they could not yet use their knowledge of letter sounds to read words.

    (1)What were the participants required to do in the study?

    A.To pick out difficult letter sounds in Danish.
    B.To learn new letters through repeated writing.
    C.To learn letter sounds using different approaches.
    D.To memorize some letter sounds as soon as possible.
    (2)How can embodied learning get children actively involved?

    A.By combining learning with games.
    B.By offering them chances to cooperate.
    C.By inspiring them to overcome difficulties.
    D.By explaining instructions to them patiently.
    (3)What does the underlined word "proficient" in Paragraph 3 probably mean?

    A.terrible.
    B.skilled.
    C.delighted.
    D.fascinated.
    (4)What does Jacob expect of the research finding?

    A.Encouraging educators to apply it to teaching.
    B.Enabling researchers to carry out further studies.
    C.Urging schools to pay attention to physical exercise.
    D.Promoting harmonious teacher-student relationships.
    (5)What does the last paragraph intend to tell us?

    A.Children prefer learning step by step.
    B.Children are too little to use their knowledge smartly.
    C.Children lack enough practice to get fully improved.
    D.Children's learning still relies on adults' instruction.

  • 2.    Have you learned a lot of English words?Well,many more are being created right now!
        Neologisms appear all the time,especially linked to new technology.This not only represents more work for you but also annoys some native speakers of English.
       Every age has its purists.Tom Chatfield,author of Netymology:A Linguistic Celebration of the Digital World,says that in the16th Century,many people disliked neologisms with foreign influences.The poet Richard Willies said that they were"smelling too much of the Latin".
       In the19th Century,the English poet William Barnes suggested that the word"photograph"should be replaced by"sun print"in order to achieve proper "Englishness".It didn't catch on.
       Now the debate about speech and writing is livelier than ever,says Mr.Chatfield.He thinks the Digital Revolution is as significant as the Industrial Revolution,and there are many inventions and processes which have to be named.
       From text messages and email to chat rooms and video games,technology has over the past few decades brought about an extraordinary new area of verbal exchange.It is not so much about foreign influence but informality and abbreviation.The Oxford English Dictionary acknowledged in 2011 the use of initials such as"oh my God"(OMG),"laughs out loud"(LOL) and"for your information"(FYI).
       We are moving away from spoken words and towards the act of typing on to a screen.We've already grown so used to saying phrases like dotcom out loud that we forget we are speaking punctuation marks.And punctuation took a life of its own with emotions.
       The speed of communication today is matched by the speed with which new words are taken up.Bicycles,automobiles and telephones took decades to become a part of daily life as words and objects.With online offerings,new words are adopted in a matter of months.The verb"to google"has become a part of dozens of languages across the world.
       Where habit leads,language follows.Only time will tell what lasts.Meanwhile,as a student of the English language,you've got a lot of catching up to do.

    (1)What does the underlined word"Neologisms"in Paragraph 2 refer to?

    A.New words.
    B.Old words.
    C.Strange words.
    D.Technological words.
    (2)How does the author prove his opinion?

    A.By experimenting.
    B.By giving examples.
    C.By asking and answering.
    D.By telling stories.
    (3)What's the author's attitude to the new words?

    A.Disappointed.
    B.Concerned.
    C.Subjective.
    D.Objective.
    (4)Which of the following can be the best title for the text?

    A.How to Learn New Words
    B.How to Invent New Words
    C.New Words,Good or Bad
    D.New World,New Words

  • 3.Earthquake rescue robots have experienced their final tests in Beijing.Their designers say that with these robots,rescue workers will be able to have more time to save more lives during an earthquake.
       This robot looking like a helicopter,is called the detectorbot.It's about 4 meters long,and it took about 4 years to develop the model.Its main functions(作用)are to collect information from the air,and send goods of up to 30 kilos to people stuck in an earthquake.
       This robot has a high quality 360 degree panoramic(全景的)camera.It can work day and night and will also be able to send the latest pictures from the quake area.Dr.Qi Juntong,from the Chinese Academy of Sciences,said, "Unlike other automatic machines,the most important feature of this robot is that it doesn't need a distant control.We just input the information of the earthquake-struck area to it,and then it takes off,and lands by itself.It flies as high as 3,000 meters,and as fast as 100 kilometers per hour."
       This robot has a different function — it can change as the environment changes.Its main job is to search for any signs of life in places where human rescuers are unable to go.
       As well as a detector(探測器) that finds victims(遇難者)and detects poisonous gas,a camera is placed in the 4-meter-long robot,which can work in the dark.
       Another use for the rescuers is the supply device,with its 10-meter-long pipe.People who are caught in the ruins will be able to get supplies including oxygen and liquids.
       Experts have said that the robots will go into production,and serve as part of the national earthquake rescue team as soon as next year.

    (1)What can we learn about the robot according to the passage?

    A.It hasn't been put into production so far.
    B.It is a machine with a length of 10 meters.
    C.It is a machine carried by a helicopter.
    D.It weighs about 30 kilos.
    (2)Why did Dr.Qi Juntong think this robot is different from the others?

    A.It has more functions.
    B.It has a more advanced camera.
    C.It can change as the environment changes.
    D.It can work by itself once given the information.
    (3)What is the passage mainly about?

    A.The appearance of the robot.
    B.An introduction to the robot.
    C.The reason for making the robot.
    D.Some information about earthquakes.
