Fresno, in the central valley, comes top of the list in America for year-round pollution. Residents’ hearts and lungs are affected as a  28  .

　　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  .And that is just what Aclima, a new firm in San Francisco, has been doing over the past few months.

　　26. M)pollutants

　　【語(yǔ)法分析】根據(jù)空格前的the level of可知，of為介詞，后面應(yīng)該加名詞，構(gòu)成介詞短語(yǔ)，同時(shí)與for構(gòu)成原因狀語(yǔ)。

　　【語(yǔ)義分析】根據(jù)開篇句中的“smog”霧霾可知，本文與環(huán)境有關(guān)。“pollutants”污染物，符合題意，“the level of pollutants”污染物等級(jí)，故選M。

　　27.N)restricted

　　【語(yǔ)法分析】Nor放在句首倒裝，正常語(yǔ)序應(yīng)為The state’s bad air is not to its south. 因此需考慮存在be to 結(jié)構(gòu)的單詞。符合的有intended和restricted。

　　【語(yǔ)義分析】be intended to打算、旨在，be restricted to局限于。根據(jù)語(yǔ)義可知，該州的空氣污染并非局限于其南部地區(qū)，故選N。

　　28. C)consequence

　　【語(yǔ)法分析】根據(jù)空前的a 可知，冠詞后應(yīng)加單數(shù)可數(shù)名詞，同時(shí)又能與as a構(gòu)成搭配。符合的有consequence。

　　【語(yǔ)義分析】as a consequence“結(jié)果”，相當(dāng)于as a result，固定搭配。致使居民的心臟和肺部受到感染，語(yǔ)義通順，故選C。

　　29. J)innovation

　　30. F)detail

　　【語(yǔ)法分析】根據(jù)空格前的in可知，介詞后應(yīng)加名詞。

　　【語(yǔ)義分析】detail細(xì)節(jié)，in detail固定搭配，詳細(xì)地。本句譯為：使得這個(gè)地方十分適用于研發(fā)及檢測(cè)污染全面監(jiān)測(cè)系統(tǒng)，故選F

　　31. K)intended

　　【語(yǔ)法分析】be to，與前文一樣，此處需要填入能與之搭配的單詞。

　　【語(yǔ)義分析】此處只有intended符合，be intended to，打算、旨在。旨在生成實(shí)時(shí)地圖……，故選K。

　　32. L)outdoor

　　【語(yǔ)法分析】根據(jù)空格前的of 可知，其后應(yīng)加名詞。air pollution名詞詞組，因此此處應(yīng)為形容詞，起修飾作用。符合的有domestic、outdoor。

　　【語(yǔ)義分析】下文講到，這種監(jiān)控站也會(huì)關(guān)注著建筑物內(nèi)部的污染情況, 所以根據(jù)inside “在……里面”可知，此空應(yīng)填outdoor，“戶外的、室外的”，室外空氣污染，故選L。

　　33. B)collaborating

　　【語(yǔ)法分析】根據(jù)空前的have been可知，此空應(yīng)填入分詞。Aclima前文提到是一家公司，應(yīng)表示主動(dòng)，所以此處應(yīng)填現(xiàn)在分詞。符合的有collaborating和creating。
