解答 46.答案:more.考查比较级.根据第一句People usually check whether their keys,wallets and phones are with them before going out出门前人们通常会检查自己的钥匙、钱包和手机是否和他们在一起.but表示转折,可知应该是现在有"更重要的"东西要带出去.用比较级形式,important多音节,比较级在前面加more.
47.答案:polluted.考查形容词.根据上句a breathing mask.一个口罩,可知应该是"他们希望它能保护他们免受污染的空气.",用polluted污染的,这里是过去分词形式.相当于形容词的功能,修饰名词air.故填polluted.
48.答案:seen.考查过去分词.根据前面Since January this year自从今年一月以来,可知用现在完成时态,再根据后面a lot of hazy days许多雾蒙蒙的天,可知应该是已经"看到",用see的过去分词seen.
49.答案:looks.考查搭配.look like看起来像.由前面的is可知,是一般现在时态,主语是that单数,因此用look的第三人称单数looks,意思是"烟雾是污浊的空气,看起来像雾和烟.".
50.答案:problem.考查名词.句意"PM2.5是空气污染的主要___".根据首字母提示,可知应该是主要"问题",用problem.
51.答案:driving.考查动名词.and连接并列成分,由后面的cars车,及burning动名词形式,可知应该是drive的动名词driving,表示"开车和燃煤是 PM2.5 的主要原因",用driving.
52.答案:especially.考查副词.根据上一句空气不好对人们的健康有害.可知这里表示强调,用"especially"尤其地,意思是"尤其是孩子和上了年纪的人."
53.答案:patients.考查名词.根据后面in the internal medicine department在内科,可知应该是"病人"patient,half of 一半的…,后跟名词复数,因此用patients.
54.答案:attention.考查搭配.pay close attention to…"密切关注…",因此用attention.
