All of which, combined with California's reputation as the home of technological __29__, makes the place ideal for developing and testing systems designed to monitor pollution in __30__.

26. 答案：M

此处需要一个名词，表示洛杉矶空气污染水平高。根据上下文，'Los Angeles is still the worst city in the United States for levels of __26__'，需要填入'pollutants'（污染物），因为污染物是衡量空气污染水平的关键指标。

27. 答案：N

此处需要一个形容词，修饰名词'air'，表示加州的空气污染不仅限于其南部。根据上下文，'Nor is the state's bad air __27__ to its south'，需要填入'restricted'（受限的），表示空气污染问题不只局限于加州南部。

28. 答案：C

此处需要一个名词，表示居民的心脏和肺部受到影响。根据上下文，'Residents' hearts and lungs are affected as a __28__'，需要填入'consequence'（后果），表示空气污染对居民健康的影响是其直接后果。

29. 答案：J

此处需要一个名词，表示加州作为技术创新的中心。根据上下文，'California's reputation as the home of technological __29__'，需要填入'innovation'（创新），表示加州以其技术创新而闻名。

30. 答案：F

此处需要一个形容词，修饰名词'pollution'，表示监测污染的地点。根据上下文，'developing and testing systems designed to monitor pollution in __30__'，需要填入'outdoor'（户外的），表示这些系统旨在监测户外污染。

31. 答案：K

此处需要一个形容词，修饰名词'monitoring stations'，表示这些站点的设计目的。根据上下文，'It has been trying out monitoring stations that are __31__ to yield minute-to-minute maps of __32__ air pollution'，需要填入'intended'（旨在），表示这些监测站旨在提供实时的空气污染地图。

32. 答案：L

此处需要一个形容词，修饰名词'air pollution'，表示监测的具体类型。根据上下文，'minute-to-minute maps of __32__ air pollution'，需要填入'outdoor'（户外的），表示这些站点能够监测户外空气污染。

33. 答案：B

此处需要一个动词的现在分词形式，表示Aclima与谷歌街景系统的合作。根据上下文，'To this end, Aclima has been __33__ with Google's Street View system'，需要填入'collaborating'（合作），表示Aclima正在与谷歌街景系统合作。

34. 答案：I

此处需要一个名词，表示旧金山的交通工人罢工时被迫使用汽车的人。根据上下文，'the city's __34__ were forced to use their cars'，需要填入'inhabitants'（居民），表示城市居民在交通工人罢工时被迫开车。

35. 答案：E（creating）

空格位于介词 by 之后，须填动名词(-ing)形式作宾语，且与上文 'revealed pollution highs'(揭示污染高峰)形成对照。''cycle to work' days have done their job by __35__ pollution lows' 意为'骑车上班日通过制造污染低值完成了它的使命'，故填 creating(创造/制造)。原答案 frequently 是副词，无法接在 by 后充当 'pollution lows' 的支配成分，语法不通；creating 既满足 by+动名词 结构，又与 highs/lows 的对照语义吻合。
