四、语法填空

• 4．The fact （1）

  humans live longer than ever before cuts both ways，because the more time we spend on the planet，the more things can go disordered in our bodies and our minds.It's a particular challenge for neurologists （2）

  want to keep our brains healthy.For decades，they have worked to create drugs to prevent，delay or treat cognitive decline in the 5 million older Americans who live with dementia（痴呆）.A miracle pill remains elusive---but researchers （3）

  （make） progress in understanding non-pharmacological strategies that might keep the brain alert and （4）

  （work） at close to its younger pace.
     So far，they have identified social engagement and learning new things as activities that （5）

  slow or delay cognitive decline and Alzheimer's.Not every kind of interference works the same，and some previous research about them has been uneven.But in the most rigorous study to date，researchers pitted different types of cognitive training head-to-head and concluded that one strategy in particular---a kind of computerized brain training that helps the mind to process information （6）

  （quickly） --- can significantly lower rates of cognitive and dementia.
     The study，led by Jerri Edward from the University of South Florida，involved nearly 3，000 healthy older people in a five-week training program.They were distributed randomly to （7）

  no intervention（干预） or one of three tracks：improving memory skills；boosting reasoning skills；and a computerized program that focused on processing speed.After five weeks，participants were followed over the course of 10 years.
     At the end of the study，only those（8）

  （assign） to the speed-processing training showed improvement.（9）

  they had only done five weeks of brain training，the effect was dramatic：that group saw a 33% reduction in the amount of dementia or cognitive impairment after 10 years compared with those who received no training.The researchers suspect that training the brain as you would a muscle--to work as efficiently as possible --- is what's （10）

  play.

五、书面表达

• 5．阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
      I always prided myself on my sharp tongue and witty（妙趣横生的） retorts（反驳），whether in class debates or casual arguments.So when it came time to represent my school in the national debate series，I was naturally very confident.But this challenge would turn out to be one of my life's most important lessons.
      The run-up to the finals was a breeze for my team.We were all good speakers who had the benefit of an experienced teacher who trained us well.But in the team，I was undoubtedly the most outstanding speaker.In each of the rounds that I debated in，I had always been selected as the best speaker.This meant that my confidence was at an all-time high by the time we found ourselves with one week left to train before the finals.I had no reason to even think that I would not be voted the overall best speaker for the debate series.
      But then I began to grow arrogant.I looked down on my teammates' pathetic retorts and poor debating style.I thought myself a natural debater being pulled down by their bad performance.In response，I became sloppy（不认真的）.I even began missing practices，much to the panic of my teammates and the frustration（沮丧） of my teacher.They could only hope I'd pull through in the end as I proved irreplaceable.
      The day of the finals came.I was nearly skipping to the venue，ready to finally show off my debating prowess（杰出的技能）.But the reality was not something I could have ever imagined.Due to my repeated absences，our teamwork was so bad that even our school supporters were shamed into silence.There was a rift（分歧） in the team.When it was my turn to conclude as speaker，an expectant hush（寂静） fell over the hall.I was the one meant to win the prized title of Overall Best Speaker.
  
  注意：
  （1）所续写短文的词数应为 150 左右；
  （2）请按如下格式在相应位置作答。
      As I launched into my speech，everything suddenly went very wrong.
  _____
      Suddenly，a teammate grabbed my hand.
