解析
(61) 该题在考查介词的用法。通过设空处后面的是冠词+名词的一个短语结构，可排除此处不需要冠词、代词和连词，所以只能是介词。结合句意，作为一种对抗心脏病的方式，填写as，“作为”
(62) 该题在考查名词单复数。该句理解为这种趋势已经有一些负面影响，例如过度肥胖和心脏病。这里出现了复数标志词some.所以effect需要用复数形式effects。
(63) 这里考查require sb to do sth，这里是它的被动结构。
(64) 这里考查when引导的时间状语从句，主将从现原则，重点考查从句部分用一般现在时态;根据句意要用被动语态。
(65) 这里考查冠词的固定搭配，as a result,结果。
(66) 这里考查形容词副词的比较级的用法。比较级的标志词有even/far/much/a bit等。
(67) 这里考查动词的时态。该句属于客观事实，应用一般现在时，而且侧重考查主谓一致。
(68) 这里考查介词+动名词的用法。
(69) 观察句子结构属于祈使句。设空处前面为系动词，做表语应该用形容词。
(70)这里考查非限制性定语从句，指代前面一件事，所以用which来充当从句里面所缺少的主语。
