Question

【題目】Have you ever paid attention (注意)to the Air Quality Index (空氣質(zhì)量指標(biāo)) or AQI reported in the newspaper? The AQI helps us understand what the air quality around us means to our health.

試題分析：這篇短文主要介紹了空氣質(zhì)量指標(biāo)幫助我們了解我們周圍的空氣質(zhì)量對(duì)我們的健康的影響�？諝赓|(zhì)量通過(guò)顏色，數(shù)據(jù)，語(yǔ)言來(lái)告訴我們空氣的情況。

【1】A細(xì)節(jié)理解題。根據(jù)數(shù)值是0-50的建議Just enjoy the clean air 故選A。

【2】D細(xì)節(jié)理解題。根據(jù)短文Air quality is fine for most people所在的表格可知是黃色，故選D

【3】C推理判斷題。通過(guò)觀察表格的數(shù)據(jù)和對(duì)應(yīng)的健康情況，可知數(shù)據(jù)越小空氣質(zhì)量越好，數(shù)據(jù)越大，空氣質(zhì)量越差，故選C.

【4】C歸納理解題。根據(jù)表格的介紹可知通過(guò)AQI colours，AQI numbers，Health words可知空氣質(zhì)量。故選C。

【5】C歸納理解題。根據(jù)所列的不同的空氣質(zhì)量時(shí)能做的事情可知有肺部疾病的人對(duì)空氣敏感，故選C。
