沈建清回答：

　　70．答案A．词义猜测题．"used"利用；常常．"stopped"停止．"chased"追捕．"produced"生产．根据原句"HowIharnessedthewind"和后文的描述可猜测，此句意思应该为，我怎样去利用风．故选A．

　　71．答案B．细节理解题．根据文章"ThomasSuarez"段落中"AfterdevelopingiPhoneappslike"BustinJeiber，"可知，ThomasSuarez在研究如何开发app．故选B．

　　72．答案D．细节理解题．根据题目中"who is working on a science project and planning to participate in an online competition"可知这个16岁的小男孩正在从事科学项目，而且要参加比赛．纵观全文，Award-winningteenagescienceinaction是关于科研项目的视频，且视频中的女孩子也参加过一些科学比赛并获取奖项．故选D．

　　73．答案D．主旨大意题．通读全文．本文讲述了几个TED演讲的视频．这些视频都是在围绕科学，并举例一些未成年的朋友也可作出的一些小小的成就．所以这些视频也是在鼓励人们要保持对科学的热情．故选D．
