Quantum(量子)computers have been on my mind a lot lately.A friend has been sending me articles on how quantum computers might help solve some of the biggest challenges we face as humans.I've also had exchanges with two quantum-computing experts.One is computer scientist Chris Johnson who I see as someone who helps keep the field honest.The other is physicist Philip Taylor.
   For decades,quantum computing has been little more than a laboratory curiosity.Now,big tech companies have invested in quantum computing,as have many smaller ones.According to Business Weekly,quantum machines could help us "cure cancer,and even take steps to tun climate change in the opposite direction . "This is the sort of hype(炒作)that annoys Johnson .He worries that researchers are making promises they can't keep."What's new,"Johnson wrote,"is that millions of dollars are now potentially available to quantum computing researchers."
   As quantum computing attracts more attention and funding,researchers may mislead investors,journalists,the public and,worst of all,themselves about their work's potential.If researchers can't keep their promises,excitement might give way to doubt,disappointment and anger,Johnson warns.Lots of other technologies have gone through stages of excitement.But something about quantum computing makes it especially prone to hype,Johnson suggests,perhaps because"quantum'stands for something cool you shouldn't be able to understand."And that brings me back to Taylor,who suggested that I read his book Q for Quantum.
   After I read the book,Taylor patiently answered my questions about it.He also answered my questions about PyQuantum,the firm he co-founded in 2016.Taylor shares Johnson's concerns about hype.but he says those concerns do not apply to PyQuantum.
   The company,he says,is closer than any other firm"by a very large margin(幅度)"to building a"useful"quantum computer,one that"solves an impactful problem that we would not have been able to solve otherwise."He adds,"People will naturally discount my opinions,but I have spent a lot of time quantitatively comparing what we are doing with others."
   Could PyQuantum really be leading all the competition"by a wide margin",as Taylor claims?I don't know.I'm certainly not going to advise my friend or anyone else to invest in quantum computers.But I trust Taylor,just as I trust Johnson.

(2)What leads to Taylor's optimismr about quantum computing?

A.Open.
B.Cool.
C.Useful.
D.Resistant.
(4)Which would be the best tide for the passage?

  • 1.You're sitting on the train home and the person opposite you yawns(打哈欠).Suddenly,you're yawning with him,though you're not tired.
       This phenomenon confused scientists for years until a recent study found that people tend to sympathize with fellow humans.Supporting this claim was the discovery that those children who were unable to form normal emotional ties with others did not experience contagious(有感染力的)yawning,which showed that humans communicate regularly with out words.
       Hugo Critchley,a neuroscientist,has conducted an experiment recently,which will prove that happiness and sadness can spread like the common cold.According to Critchley,our minds and bodies are in constant exchange about how we're feeling. "Emotions are closely linked with states of internal(內(nèi)部的)responses,"he explained."There are also more visible changes in our gestures and facial expressions.When we're in a group,these signals can spread to another person.For example,there's the obvious tendency to smile when smiled at and there are less obvious changes that reflect emotions of surprise,anger or sadness such as a change in our heart rate and blood pressure."
       Hugo Critchley further explained,"Our bodies synchronise and when we like the other person,we ever copy his behavior.Next time you chat with a friend,take note of how you're sitting-it's pretty likely that you will be the same.Scientists believe it's our way of telling each other that we're partners.Through body language,humans give each other very subtle(微妙的)but clear signals that show emotions."
       So,what lessons can we learn from this?"Spend time with happy people-otherwise your health could suffer,"said Critchley."When we're sad,our body goes into fight or flight mode.But when we're happy,our body works normally and we feel relaxed and positive.So we look bright,our skin glows,we feel healthy and it affects everyone around us."

    (1)According to Hugo Critchley,
    .
    A.emotions are as visible as facial expressions
    B.we yawn more frequently when we have a cold
    C.emotions are connected with states of internal responses
    D.the change of blood pressure is not linked with the change of emotions
    (2)The underlined word "synchronise"in Paragraph 4 means
    .
    A.move slowly
    B.change rapidly
    C.relax temporarily
    D.respond accordingly
    (3)From the passage we can learn
    .
    A.sadness is as contagious as happiness
    B.a(chǎn)nger is less contagious than smile
    C.surprise is more contagious than smile
    D.surprise is the most contagious among emotions
    (4)Which of the following statements is true according to the passage?

    A.Emotions have delicate influence on fellow humans.
    B.Children like copying the actions of the fellow humans.
    C.Scientists are still confused about contagious yawning.
    D.People tend to communicate more with body language.

  • 3.Every year in May,art galleries and museums prepare shows to honor Leonardo Da Vinci,who died in France on May 2,1519.He is remembered as one of the greatest artists and creative thinkers of all time.His most famous paintings are The Mona Lisa and The Last Supper.
        Recently,researchers have been studying a painting—Landscape 8 P which,they think,is Da Vinci's earliest-known artwork.They used special lighting to study the artwork and discovered there were two images(圖像),not one.One drawing is on the back of the piece,which dates back to August 5,1473.
        The drawing on the front was painted when Leonardo was 21 years old.It shows a river valley and a castle outside the city of Florence.There is little left of the drawing on the back,perhaps because it was wiped off.Only a bridge over a river can be seen.But there is writing on both sides.
       The writing on the front gives the date and goes from right to left.Some people would call this "mirror-writing".It's a way Leonardo often wrote in his notebooks.The writing on the back goes from left to right and tells about an agreement,probably to produce a work of art.
       Cecilia Frosinini is an art historian.She said,"Leonardo was born left-handed,but was taught to write with his right hand from a very young age.By looking at his writings,including from this drawing,we can see his right-handed handwriting is educated and well done. "
        Experts compared the two handwriting samples(樣本)and said they were both made by Leonardo.They show he could write well using his left hand or his right hand.
       The drawing is known as Landscape 8 P from its number in an art list.It will be part of an exhibit at Italy's Uffizi Gallery.The gallery director,Eike Schmidt,said by studying the drawing researchers gave us a new way of looking at Leonardo's drawing technique and his abilities in writing.

    (1)Which of the following mentioned in the text has been studied by researchers recently?

    A.The Mona Lisa.
    B.Landscape 8 P.
    C.Mirror-writing.
    D.The Last Supper.
    (2)What does the writing on the back probably tell about?

    A.A statement about the painting.
    B.An introduction about Leonardo.
    C.An agreement to produce a painting.
    D.Something about the city of Florence.
    (3)What can we learn about Leonardo from Cecilia's words?

    A.He could write with either of his hands.
    B.He did bad in right-handed handwriting.
    C.He wasn't good at writing with his left hand.
    D.He taught himself to write with right hand.
    (4)What's Eike Schmidt's attitude towards the research?

    A.Unclear.
    B.Indifferent.
    C.Doubtful.
    D.Positive.
