   Improving heating，especially in a loud environment，is just like any other skill—it takes practice．

    Research shows that musicians--despite often working in conditions that can produce hearing loss are better able to pick out speech from surrounding noise as they grow old compared to non-musicians．And a new study of auditory(听觉的)training with a commercially available brain training program suggests that most people who are hard of hearing can develop the same skills．In a report published in the Proceedings of the National Academy of Sciences，scientists showed that people trained for 40 hours over 8 weeks with Posit Science’s“Brain Fitness”were able to pick out 41％more words from background noise compared to those who watched educational DVDs and were quizzed on their contents after the same amount of time．

    The research included 6 7 older adults between 5 5 and 70，with an aver—age age of 63．The auditory training can3_e in the form of computerized hearing tasks that made the participants ready to hear better by requiting them to identify various speech．sounds and distinguish between similar sounding syllables(音节)，for example，as well as repeating back words and remembering  stones．

   Both those who received the training and those who watched the DVDs were tested on short term memory，brain processing speed and the ability to hear speech in noisy settings．All of the participants showed improvement in these three measures，but for the first time，the scientists also documented that the sharper hearing Was accompanied by earlier signaling in the brain-stern．As the authors write in their paper，the training sped up the brain’s ability to respond to it bringing it to more“youthful’’ levels．

32．We can learn from Paragraph 2 that________.

A musicians  can ignore all the noise

B.．musicians have the best hearing ability

tory training can partly help improve the hearing ability

D．auditory training can help all people，especially the musicians

 33·What does“Brain Fitness"refer to?

    ’s a kind of noisy setting．

    B.．It’s a kind of auditory trainings．

    C. It’s  an educational DVD．

    ’s a name of a journal

 34．How was the auditory training carried out7 

    asking the．participants to recite similar sounds．

    B.．By comparing them with those who watched educational DVDs．

    C·By identifying various sounds and sounding syllables．

    D．By telling stories and distinguishing different syllables．

35·We can learn from the passage that______． 

    A. young participants performed better than old ones

    B the training made old people feel they are still young’

    C. watching DVDs does no good to people’s intelligence

．  D．those who were trained responded to the speech more quickly
