    5．Which part of the world has the most nearsighted students？Just look around you-it's East Asia．Nine in ten school leavers in major East Asian cities are nearsighted，according to the BBC．Experts say books and video games are not to blame．East Asian students，they say，aren't getting enough sunlight．
    People become nearsighted because their eyeballs grow out of shape and light entering their eyes cannot focus correctly．The body can produce a chemical called dopamine （多巴胺） to stop eyeballs from changing shape．And guess what scientists have just discovered？Sunlight can help our bodies produce more dopamine，reported AFP．
    According to the study，primary school students in Singapore spend only 30minutes outdoors every day； in Australia，by contrast，kids spend about three hours a day outside．As a result，fewer children in Australia are nearsighted-only 10percent，compared with 90percent in Singapore．
    "Children in East Asia basically go to school…go home and stay inside．They study and they watch television，"Ian Morgan of the Australian National University told AFP．
    But being a bookworm or a couch potato does not directly harm the eyes，added Morgan．"As long as they get outside，it doesn't seem to matter how much study they do，"he explained．"There are some kids who study hard and get outside and play hard and they are generally fine．The ones who are at major risk are the ones who study hard and don't get outside．As a result of massive （巨大的） educational pressures and the construction （构成） of a child's day，the amount of time they spend outside in bright light is minimized．"
    Experts suggest children should stay outside for two to three hours every day．This can include time spent in the playground and walking to and from school．

    41．Which of the following word has the similar meaning as the underlined phrase"nine in ten"？D
    A．many     
    B．much        
    C．more       
    D．most
    42．What is the main reason for the large number of nearsighted students in East Asia，according to scientists？B
    A．Too much reading or gaming．
    B．Lack of sunlight．
    C．Genetic reasons．
    D．Lack of exercise．
    43．What can we conclude from Paragraph 2？D
    A．Dopamine is a chemical that causes eyeballs to grow out of shape．
    B．Dopamine can stop light entering the eyes from focusing correctly．
    C．Spending time in the sun can make the loss of dopamine in the body．
    D．The more dopamine a person has in their body，the better eyesight he or she has．
    44．According to Morgan，what kind of people are most likely to suffer from nearsightedness？D
    A．Those who like watching TV．
    B．Those who take exercise regularly．
    C．Those who study hard and play hard outdoors．
    D．Those who stay indoors studying all day．
    45．The word"minimized"in second-to-last paragraph probably meansA．
    A．reduced as much as possible
    B．made better use of
    C．taken little notice of
    D．attached much importance to．
