解答 36-40 CACBD 41-45 ABDCC 46-50 BDACB 51-55 AACBD
36.C考查副词.室内污染有时候是室外污染的2-3倍,"occasionally"意思是"偶尔"是室外污染的100倍.
37.A考查名词.根据前句可知,室内污染和严重,所以应该是特别需要注意的"concern"意思是名词,"在意关心的事情".

39.B考查动词.此处考查一个固定短语,"show up"意思是"出现".
40.D考查形容词.前句提到"eyes,nose,throat and headaches"这些都是属于"short-term"短期的影响.
41.A考查连接词.if此处引导一个条件状语产品从句,意思是"如果能够鉴别污染源的话,治疗很简单".
42.B考查形容词.根据"so it is often difficult to determine"有些很难决定,因为和"colds or other diseases"感冒很相似.
43.D考查名词.如果这些症状是因为室内污染源引起的结果的话就很难决定."result"意思是"结果"符合题意.
44.C考查动词.所以要注意症状出现的时间和地点,此处考查一个固定短语"pay attention to"意思是"注意".
45.C 考查名词.根据上文"so it is often difficult to determine if the symptoms"可知,此处填症状"symptoms"属于原词复现.
46.B考查动词.根据后面的"go away"可知所填的动词应该和"go away"有类似的意思,所以"fade"意思是消失.
47.D考查名词.当一个人离开家,症状就消失了,回来症状就出现的话,应该努力找一下室内污染源,make efforts意思是努力.
48.A考查介词."by"此处是介词,意思是通过某种方式.
49.C考查形容词.前句提到"years after exposure"可知,长时间的重复暴露在室内污染物之下.
50.B 考查副词. 根据句子里"some respiratory(呼吸的) diseases"一些呼吸疾病可能是最严重的,severly副词来修形容词fatal.
51.A考查介词短语.根据上下文语境可知,即使没有出现症状也要最好改善室内空气质量."even if"意思是"即使"符合题意.
52.A考查动词.此处found in indoor air 属于过去分词短语修饰pollutants,表示被动.
53.C考查副词.根据上句"there is considerable uncertainty about"还不太确定暴露的什么阶段会引起疾病,所以不同人对污染源的反应也是不同的.
54.B考查连接词.根据上下文的语境可知,此处therefore表示因果关系,因此,需要进一步的研究.
55.D考查动词.由于前句提到还不太确定暴露的什么阶段会引起疾病,所以更好理解室内污染的 影响是有必要的.
