21. The view of Wordsworth about habit is claimed by being _____.

　　C) mechanical

　　本题问Wordsworth对habit的观点，根据人名定位到第一段，“Not choice, but habit rules the unreflecting herd,” William Wordsworth said in the 19th century. 注意Wordsworth话中but后面的内容“习惯支配着不会思考的兽群”，C) mechanical(机械的)可以说是对unreflecting的替换，此外我们还可以从We reach for them mindlessly, setting our brains on auto-pilot and relaxing into the unconscious comfort of familiar routine.加以推断，这句话的大意为，习惯是无意识地(mindlessly)、是自动地(auto-pilot)、很放松地进入惯例之中的舒适中(the unconscious comfort of familiar routine)。考生如果觉得这样的推理比较复杂的话，也可以从第一段中对习惯的描述的词的褒贬加以判断。

　　22. The researchers have discovered that the formation of habit can be ___.

　　D) guided

　　本题问研究者发现习惯的形成可以怎么样？我们定位到第二段So it seems antithetical to talk about habits in the same context as creativity and innovation. But brain researchers have discovered that when we consciously develop new habits, we create parallel synaptic paths, and even entirely new brain cells, that can jump our trains of thought onto new, innovative tracks.第一句说creativity 和innovation 与habit是互不相容的，接着文章用but表示转折，在这种情况下我们可以推测后面的内容是讲creativity 和innovation与habit是相容的，研究者发现了什么呢？当我们有意识地(consciously)形成新的习惯时，我们甚至能够创造全新的脑细胞，这能够使我们的思绪跳跃到新的创新的轨道上(that can jump our trains of thought onto new, innovative tracks，这句话中that指代create parallel synaptic paths, and even entirely new brain cells)。“使我们的思绪跳跃到新的创新的轨道上”不就是guide吗？

　　23. "ruts" has closest meaning to___.

　　A) tracks

　　本题为词义推断题，必须从上下文中加以理解，But don’t bother trying to kill off old habits; once those ruts of procedure are worn into the hippocampus, they’re there to stay. Instead, the new habits we deliberately ingrain into ourselves create parallel pathways that can bypass those old roads.首先我们由they’re there to stay，知道ruts是一个具体的东西，接着由the new habits create parallel pathways that can bypass those old roads.我们可以知道ruts与pathways、roads应该是同义替换的，由此选择A) tracks.

　　24. Ms. Markova's comments suggest that the practice of standard testing ____.

　　A) prevents new habits from being formed

　　本题问Markova的评论意味着标准化测试会怎么样。本题跨度较大，首先必须找到Markova的评论，“But we are taught instead to ‘decide,’ … ” She adds, however, that “to decide is to kill off all possibilities but one. A good innovational thinker is always exploring the many other possibilities.”

　　Markova认为我们被教育要学会"决定"，但决定扼杀了所有的可能性，只留下一个答案，一个有创新性的思考者总是考虑许多其他的可能性的。接着我们找到文中关于 标准化测试的描述The current emphasis on standardized testing highlights analysis and procedure, meaning that few of us inherently use our innovative and collaborative modes of thought.大意为目前标准化测试只强调了analysis与procedure，这从根本上使得很少有人能够使用 innovative与collaborative的思维模式。找到了两个出处，我们就必须找到“Markova的评论”与“标准化测试”的联系，到底有什么联系呢，我们不难发现由Markova的评论我们知道标准化测试“从根本上使得很少有人能够使用 innovative与collaborative的思维模式”，而从第二段的描述中我们知道创新性对于新习惯的形成是至关重要的。因此选择A) prevents new habits from being formed。

　　25. Ryan most probably agrees that ______.

　　D) curiosity activates creative minds

　　本题问Ryan最可能同意什么观点。

　　A) ideas are born of a relaxing mind 观点来源于放松的大脑。

　　B) innovativeness could be taught 创新能够被传授。

　　C) decisiveness derives from fantastic ideas 果断来自于奇特的想法。

　　D)curiosity activates creative minds好奇心能够激活创新的头脑。

　　根据人名Ryan我们可以定位到最后一段，但很难从中找出与四个选项匹配的观点，不过我们注意到Ryan与Markova是business partner的关系，这两人之间的观点是一致的，由“The first thing needed for innovation is a fascination with wonder,” says Dawna Markova.我们知道Markova认为创新最需要的就是对未知事情的着迷，因此选择D)curiosity activates creative minds。

　　而A) ideas are born of a relaxing mind 利用文中出现的relaxing加以编制选项。B) innovativeness could be taught 虽然文中最后一段Knowing what you’re good at and doing even more of it creates excellence.”This is where developing new habits comes in. 但只是说doing even more of it creates excellence.并没有交代是本人自觉得多做，还是被“taught”的多做。C) decisiveness derives from fantastic ideas文中没有关于果断的信息。

　　26. In paragraph 1 and 2, the text shows PTK's ____.

　　A) easy availability

　　本题问文章的第一二两段显示了PTK的什么。[b]All he needs to do[/b] is shell out $30 for a paternity testing kit at his local drugstore—and another $120 to get the results.

　　[b]More than 60,000[/b] people have purchased the paternity testing kits since they first became available [b]without prescriptions[/b] last year, according to Doug Fogg, chief operating officer of Identigene, which makes the [b]over-the-counter[/b] kits. [b]More than two dozen companies[/b] sell DNA tests [b]directly[/b] to the public, ranging in price from a few hundred dollars to more than $2,500. 由这些粗体All he needs to do，More than 60,000，without prescriptions(无须处方)，over-the-counter(通过柜台)，sell DNA tests directly to the public我们就很容易得出A) easy availability易得性(很容易得到)。

　　30. An appropriate title for the text is most likely to be ______.

　　B) DNA tests and its problems C) DNA testing outside the lab

　　本题问文章最有可能的标题是什么，文中对DNA testing outside the lab虽有涉及，但是but some observers are skeptical, critics also argue 这两段是大头，重点信息，说明了存在的问题，所以C不完整，此外系谱学家(genealogists)的研究也需要实验室的，文中只是交代了进行DNA测试可能出现的问题，是在实验室内外都有可能出现的问题。

　　32. It is stated in paragraph 1 that the construction of a new education system _____.

　　B) takes efforts of generations

　　本题问第一段中对于新的教育体制的建立的描述。本题定位非常明确We are fortunate that it is, because building new educational systems there and putting enough people through them to improve economic performance would require two or three generations.句子大意为，很幸运前面的传统观点是错误的，因为，建立新的教育体制并让足够的人通过(并让足够的人接受教育)，想靠这种方法改善经济水平需要2至3代人的努力。因此不难得出B) takes efforts of generations，而D) requires sufficient labor force，文中提到的them不是labor force，而是需要通过教育体制的人，并且要靠这些人通过教育体制来改善经济需要几代人的努力，并没有提到新的教育体制的建设需要充足的劳动力，两者之间没有关系。

　　34. The author quotes the example of our ancestors to show the education emerged ____.

　　C) when people no longer went hungry

　　本题问作者引用祖先的例子是为了说明教育是在什么情况下出现的，我们定位到原文What is the real relationship between education and economic development? I have begun to suspect that continuing economic growth promotes the development of education even when governments don't force it. After all, that's how education got started. When our ancestors were hunters and gatherers 10,000 years ago, they didn't have time for education. They didn't have time to wonder much about anything besides finding food. Only when humanity began to get its food in a more productive way was there time for other things.文中的例子是为此段的主题服务的，那么此段的主题是什么呢？理解主题需要知道suspect的深层含义：怀疑其为真，第二，要知道I have begun to suspect that continuing economic growth promotes the development of education even when governments don't force it. [b]After all, that's how education got started.[/b]中的后一个that指代，that就是指代continuing economic growth promotes the development of education even when governments don't force it. 因此我们选择C) when people no longer went hungry在解决了温饱的情况下才可以谈教育。第三，虽然例子中谈到了时间，但没有时间是什么造成的呢？是需要花时间去找猎物来填饱肚子而没了受教育的时间～,C答案流于表面化，只有是否饿肚子和经济发展逻辑上相关。
