68．考查副词。句意：他们解释说，如果你的两只手彼此间搓得太慢、太轻，流动的水产生的力就不足以克服将粒子压下来的力。设空处在句中与前面的slowly一样，修饰动词move，做状语，故应用副词形式。故填gently。
69．考查主谓一致。句意：他们确认，在不考虑使用肥皂的情况下，20秒是洗手有效去除细菌的最短时间。设空处在that引导的宾语从句中作谓语，结合上下文可知，本文是在陈述一些客观事实，通篇都用现在时态，故此处也用一般现在时即可；其主语为20 seconds，此处作为一个整体，表示“20秒是洗手有效去除细菌的最短时间”，意义上表示单数，故谓语也需用单数。故填is。
70．考查形容词。句意：他们确认，在不考虑使用肥皂的情况下，20秒是洗手有效去除细菌的最短时间。设空处在句中修饰名词hand-washing，作定语，应用形容词形式；结合句意及提示词可知，此处应用effective，表示“有效的”。故填effective。
71．achievement 72．interested 73．It 74．to run 75．to 76．exercising 77．greatly 78．which 79．crossed 80．stronger
【导语】这是一篇记叙文。作者通过讲述自身经历表明每天跑步30分钟这样简单的事情可以积极改善生活。
71．考查名词。句意：为什么不尝试一些新的东西来提高你的成就感，并长期改善你的生活呢？sense of achievement意为“成就感”，为固定搭配，所以此处应用名词achievement表示“成就”作宾语。故填achievement。
72．考查形容词。句意：以我为例，我从来没有对跑步很感兴趣。be interested in意为“对……感兴趣”，为固定搭配，所以此处应用形容词interested表示“感兴趣的”作表语。故填interested。
73．考查代词。句意：直到那时我才意识到我真的需要开始跑步。去掉空格和that后句子完整，所以此处为it强调句句式，句首首字母应大写。故填It。
74．考查动词不定式。句意：一天下班后，我决定长途跋涉。decide to do意为“决定做某事”，为固定搭配，所以此处应用to do不定式作宾语。故填to run。
75．考查介词。句意：虽然我的腿在路上受伤了，而且很痛，但我找到了其他娱乐方式无法给我的满足感。give sth to sb意为“把某物给某人”，为固定搭配，此处关系代词which作give的宾语，所以此处应用介词to。故填to。
76．考查动名词。句意：通过每天锻炼，我的心肺功能大大改善，脂肪肝也得到了恢复。在介词by后应用动名词作宾语。故填exercising。
77．考查副词。句意：通过每天锻炼，我的心肺功能大大改善，脂肪肝也得到了恢复。修饰动词improved应用副词greatly表示“非常地，极大地”作状语。故填greatly。
78．考查定语从句。句意：上周，我跑了马拉松的前半程，与大约100名年轻运动员进行了比赛，我以极大的决心成功地越过了终点线。在非限制性定语从句中缺少介词in的宾语，且先行词为“my first half of the marathon”，所以应用关系代词which。故填which。
79．考查一般过去时。句意：上周，我跑了马拉松的前半程，与大约100名年轻运动员进行了比赛，我以极大的决心成功地越过了终点线。根据“Last week”可知，此处应用一般过去时。故填crossed。
