    8．Have you ever heard that we humans use only ten percent of our brains？This opinion holds a certain appeal because if it were true，then we could instantly become ten times more intelligent just by firing up that sleepy majority of the brain!
    The idea that we use only a small part of the brain dates back to animal experiments in the 19th century．When scientists stimulated （刺激） a specific part of the brain，the animal moved its leg or tail．If a tiny part of the brain could do something so great，what was the use of the rest of the brain？Some scientists assumed that large parts of the brain were simply useless．
    Then，in the early 20th century，scientists observed that stimulating certain parts of the brain had no physical effects．They named these seemingly useless parts of the brain the"silent cortex．"Today we know that in humans，much of the"silent cortex"is actually devoted to complex activities like language，learning，and imagining．
    Brain scans have shown that different parts of the brain become much more active as we shift （切换） our attention and focus，but even as we sleep，many areas of the brain are extremely active．Would you be smarter if your entire brain constantly worked to maximum capacity （能力）？Interestingly enough，the opposite is probably true．The less brain activity you need to perform a given task，the more the brain as a whole is able to do．

    28．Why does the opinion mentioned in paragraph l seem appealing？A
    A．People wish to become much smarter．
    B．People believe it is scientific．
    C．People know nothing about the brain．
    D．People want to make little use of their brain．
    29．What did scientists discover in their experiment in the 20th centuryC？
    A．The majority of the brain is sleeping．
    B．Animals'legs and tails have some connection with their brain．
    C．Stimulation on some parts of the brain causes no physical reaction．
    D．Certain parts of the brain are devoted to language and learning activities．
    30．"Silent cortex"has proved to beB．
    A．sensitive to stimulation
    B．useful in complex activities
    C．responsible for physical reaction
    D．more active than the other parts of the brain
    31．If you need less brain activity to perform a task，D．
    A．you will feel sleepy
    B．you must shift your focus
    C．you can use your brain to the fullest
    D．you will be more productive．

    14．Children who spend more time outdoor may have a lower risk of becoming near-sighted，new research suggests．
       In the study，researchers looked at about 1，900 schoolchildren in China．The scientists found that the kids who had been instructed to spend more time outdoors over three years were 23 percent less likely to develop near-sightedness during this time than those who had not been instructed to spend more time outdoors．Moreover，among the kids who did become near-sighted during the study，the degree to which their eyesight worsened was slightly smaller among those who spent more time outdoors．
       In the study，the researchers selected six schools and required the children，whose average age was 7 at the start of the study，to attend one additional 60-minute class of outdoor activities during each school day for three years．The parents of these children were also encouraged to engage（使参加） their children in outdoor activities after school，especially during weekends and holidays．The other half of the children，from another six schools，continued their usual activity patterns．
       After three years，30.4 percent of the kids in the intervention（干预） group had become near-sighted，compared with 38.5 percent of the kids in the control group，the researchers found．
       The reduction in the risk of near-sightedness found in the study is important，because children who develop near-sightedness at a young age are most likely to develop worse myopia （the medical term for near-sightedness） later on，the researchers said．
    It is not clear exactly why spending more time outside would benefit children's eyesight．However，some research has suggested that the higher levels of light intensity found outdoors may increase the release of the chemical dopamine from the retina（视网膜） of the eye，which is beneficial to eyesight．In turn，dopamine is known to inhibit the type of growth in the eye that is associated with myopia．
    Based on the new results，the researchers recommend that children spend more time outdoors because of the potential benefits to their eyesight．However，it's important to protect kids'skin and eyes from UV light，which can be damaging．
    28．What is the main idea of the passage？A
    A．Parents should engage children in outdoor activities．
    B．Kids who often play outside may have better eyesight．
    C．Kids are unlikely to gain weight if they usually play outdoors．
    D．Recently researchers have discovered a cure to near-sightedness．
    29．How many schools are involved in the study in total？B
    A.3                    B.6                        C.9                        D.12
    30．The underlined word"inhibit"in the last but one paragraph meansA．
    A．prevent       B．cause               C．encourage                D．preserve
    31．Which of the following is true according to the passage？C
    A．About 1，900 seven-year-old schoolchildren have participated in the study．
    B．Parents of the children in the control group were also involved in the study．
    C．When playing outside，children should protect their skin and eyes from the sun．
    D．Based on the results，scientists found out why staying outside benefits eyesight．
