29、同样，人类如果连续几天不睡觉，就会生病。故选C。2E该段首句提出了第一个假设，睡眠帮助我们巩固新的记忆。与这个论点相呼应的例子是E项，该项中的that指代的就是前面的假设，也就是说，这个假设能够解释为什么学生在学习完如果有机会睡一觉，他们会在考试中发挥更好。3F由下段首句中的代词he可知，该空中必然包含一个人名，否则he就失去了所指对象，浏览各选项，可锁定F项和G项，但只有F项能与本段的内容衔接，也就是说，睡眠会帮助清除记忆，为新记忆腾出空间。按照研究人员Tononi的说法，睡眠是我们为学习付出的代价。4G该段首句说“现在我们有最直接的证据证明他的假设是对的”，那接下来应该是具体描述该证据。此
30、外，该空后面一句话解释了实验的结果和意义。综合看来，只有G项符合语境，指出了研究团队、实验对象及实验内容。5B由最后一段第二句及空格后的“you keep what matters (你记住要紧的事情)”可知B项“这就好像是大脑在保存最重要的记忆。”符合语境。.语法填空It is a great 1._(true) that life is difficult.Once we really understand and accept it，then life is no longer difficult.2._，most of us do not fully see it.They just

34、它，生活就不再困难。正因为如此，明智的人应学会不要害怕，而要欢迎问题带来的痛苦。1truth考查名词。根据上文，great是形容词，修饰名词，故填truth。2However考查副词。句意：一旦我们真正理解并接受它，生活就不再困难。然而，我们大多数人并没有完全认识到这一点。此处前后句是一种转折关系，因为空前有逗号，故答案为However。3What考查主语从句。句意：让生活变得困难的是，面对和解决问题的过程是非常痛苦的。此处是主语从句，从句缺少引导词，从句谓语动词缺少主语，结合句意可知，答案为What。4based考查非谓语动词。问题的本质决定了它会引起悲伤、遗憾、愤怒或恐惧。本句为过去分词作
35、后置定语修饰problems，故填based。5uncomfortable考查形容词。句意：这些都是不舒服的感觉，通常和身体上的疼痛一样痛苦。此处是形容词修饰名词，结合句意可知，答案为uncomfortable。6that考查强调句式。句意：在解决问题的整个过程中，生命才有了意义。结合句意可知，此处是强调句型，故答案为that。7to solve考查非谓语动词。短语the ability to do sth.意为“做某事的能力”，是动词不定式作后置定语，故答案为to solve。8Learning考查非谓语动词。本句已经存在谓语动词且句中没有连词，故learn只能作非谓语，在句中作主语应用动名词形式，故填Learning。9of考查介词。句意：从遇到和解决问题的痛苦中学习是非常有益的。固定短语be of great benefit意为“非常有利”，故答案为of。10the考查定冠词the。此处表示“特指”，故答案为the。
