Question

2．上海世博会举行的主题是"城市，让生活更美好"
Shanghai World Expo hascomeupwith the theme"Better City，Better Life"．

Answer 1

分析 come up．

解答 答案：come up．结合句意可知举行的主题这个动作发生在过去，对现在造成一定的影响，故用现在完成时have/has+过去分词，结合后面的with用come up with提出，come的过去分词是come，故答案是come up．

点评 come up with是一个没有被动语态的动词短语，在课文中意为"提出""想出"． 同义词组为think of．如：She came up with a new suggestion to solve the problem as well．
她也提出了一种解决这个问题的新建议．
We have to come up with the practical measures to prevent the air pollution．
我们必须找到防止空气污染的切实可行的办法．
It's wonderful for you to come up with such a good idea．你能想出这么一个好主意真是太棒了!
