1.They use computers to keep the traffic ______(run) smoothly.请问应该用run的什么形式?为什么?应该是keep sth doing 还是keep sth done
答案：running
解析：要弄明白这问题,需要搞清以下几个问题：
1) 关于词义
* traffic 在这里是具体名词,指往来的行人车辆等,本身具有行为能力.
* run 表示车辆及行人的行驶,可以是 traffic 执行的动作
2) 关于 keep the traffic running 和 keep traffic run
* keep the traffic running.
-- 现在分词 running 是traffic 实施的动作,后者是前者的逻辑主语,它们是主谓关系,意思是保持车辆及行人自身动作并不间断地通行.
* keep the traffic run
-- run 是过去分词,其行为对象是 traffic,它们是动宾关系,run 就变成及物的役使动词,逻辑主语转移到句子的主语 computer,意思就成了“电脑实施动作推动着车辆及行人顺利通行”,而不是车辆及行人主动通行.
2.Now that we've discussed our problem,are people happy with the decisions _______?
答案：C taken
解析：
1）原因状语 Now that（既然）...的完成时态指出“既然我们已经讨论过我们的问题”,接下来主句提出了“那么人们对采纳这些决定是否感到高兴”的问题.根据推理,讨论过的问题一定是做出了决定斌接采纳.
2）A.take 和 decisions 没有语法关系,不能选择；B.to take 是不定式,表示未来行为,且与 decisions 是主谓关系,不合逻辑；C.taken 是过去分词,与 decisions 是动宾关系,即“被采纳的决定”.
