　　Passage Two

　　As we people hit middle age, we often start to notice that our memory and mental clarity are not what they used to be.We suddenly can't remember where we put the keys just a moment ago, or an old acquaintance's name, or the name of an old band we used to love.

　　This loss of mental focus can potentially have a bad impact on our professional, social, and personal well-being. Neuroscientists are increasingly showing that there's actually a lot that can be done. It turns out that the brain needs exercise in much the same way our muscles do, and the right mental workouts can significantly improve our basic cognitive functions. Thinking is essentially a process of making neural connections in the brain. To a certain extent, our ability to excel in making the neural connections that drive intelligence is inherited. However, because these connections are made through effort and practice, scientists believe that intelligence can expand and fluctuate according to mental effort.

　　Now, a new San Francisco web-based company has taken a further step and developed the first "brain training program", Lumosity, to actually help us improve and regain our mental sharpness. Lumosity, is far more than an online place to exercise our mental skills. The program keeps track of our progress and provides detailed feedback on our performance and improvement. Most importantly, it constantly modifies and enhances the games we play to build on the strengths we are developing—much like an effective exercise routine requires us to increase resistance and vary our muscle use.

　　19. What common problem do middle-aged people have?

　　20. What good can thinking do to people?

　　21. What's the purpose of designing the program Lumosity?

　　22. What is the most important feature of Lumosity?

　　参考答案：

　　【小题19】A

　　【小题20】A

　　【小题21】B

　　【小题22】D

　　习题解析：

　　【小题19】短文在开头就提到人到中年often start to notice that our memory and mental clarity are not what they used to be，也就是说，中年人的记忆力大不如前了。因此答案为选项A。

　　【小题20】此题是针对思索的益处进行提问。短文中说Thinking is essentially a process of making neural connections in the brain.由此可知，思索可以帮助大脑建立神经连接。因此答案为选项A。

　　【小题21】短文中提到developed the first "brain training program", Lumosity, to actually help us improve and regain our mental sharpness.由此可知，人们设计Lumosity的目的是为了改善大脑的功能。因此答案为选项B。

　　【小题22】短文中提到Lumosity 最重要的一点是it constantly modifies and enhances the games we play to build on the strengths we are developing，也就是说，它会根据使用者的变化来不断进行调整。因此答案为选项D。
