12.over23000/23000.

13.B

14.(at)(the)Nextmeeting/(the)followingmeeting

15.A

16.onon解析:focuson意为“集中于”,为固定短语。

17.airair解析:由前面的smog可知,此空处应填与smog相应的物质,又由后面的“hoversovercities”可知,此物质只能是“脏空气”。

18.asas解析:此处为因果关系,意为“因为许多人没有…”,因此此处应填填连词“as”。

19.firstfirst解析:根据题意,作者想在这里做一个比较,而比较的对象是目的。这里作者仅仅给出了两个目的,所以这里是和第一个目的进行比较。故答案为first。

20.gogo解析:gotoone'sheads的意思是“展现、表现”,俗语。用在文中表示“把…写在脸上”,生怕别人不知道的显摆。故答案为go。

21.whatwhat解析:解析同上。这里是一个名词性从句,what在句中做主语。故答案为what。

22.thatthat解析:参见32题解析,idea与bigachievementsrar
