【解析】

本文是一篇说明文，介绍了研究人员发现锻炼不仅对身体有益，还可以改善记忆力，仅仅十分钟的轻微运动就会对记忆产生积极的影响，目前研究人员人在研究轻微运动对老年人的影响。

1.考查副词。句意：研究人员最近发现，锻炼不仅对身体有益，还可以改善记忆力。修饰动词found用副词，故填recently。

2.考查时态。句意：在报告中，美国和日本的研究人员介绍了他们的试验和结论。动作发生在过去，应该用一般过去时，故填introduced。

3.考查定语从句。句意：科学家请了36个二三十岁的志愿者在做记忆测试之前做十分钟的轻微运动，测试中他们被展示西兰花或野餐篮的图片，稍后让他们回忆它们。此处为定语从句，先行词为volunteers，指人，关系词在从句中作主语，故填who/that。

4.考查时态语态。句意参考上题解析，which they 与show之间是被动关系，而且发生在过去，故填were shown。

5.考查形容词。句意：记忆测试实在是太具挑战性了。作表语用形容词，故填challenging。

6.考查宾语从句。句意：我们用非常相似的东西来观察他们是否记得它是这个野餐篮还是那个野餐篮。whether…versus…表示“是……还是……”，故填whether。

7.考查非谓语动词。句意：他们发现，锻炼的人的大脑与记忆的存储和回忆有关部分之间的交流增加了。be involved in表示“卷入、涉及”，此处去掉be作定语，故填involved。

8.考查介词。句意：这表明，仅仅十分钟的轻微运动就会对记忆产生积极的影响。have an effect on表示“对……有影响”，故填on。

9.考查定冠词。句意：由于所有参与试验的志愿者都相对年轻，研究人员仍在工作以观察轻微运动对老年人的影响。此处特指那些参加试验的志愿者，故填the。

10.考查不定式。句意参考上题解析，根据句意可知，此处表示目的，用不定式作目的状语，故填to look。
