1.【C1】(B)
A. extraordinary
B. additional
C. typical
D. excessive
解析：上句说明研究者花了数十年证明吸烟的危害性，此句承接上句，提到二手烟同样会致人死亡。二手烟的危害这一结论应当是在“吸烟有害”的结论上经过额外的时间和研究得出来的。B项additional“额外的”符合语义要求。
2.【C2】(C)
A. vapor
B. fire
C. legacy
D. cloud
解析：空格处名词为动词left的宾语，说明室内的吸烟者们(indoor smokers)会在吸完烟后留在室内的物质，且该物质还能持续数年。C项legacy“遗产，遗留物”代入后与空格前的toxic搭配能表示“有害的遗留物”。
3.【C3】(B)
A. develops
B. mixes
C. covers
D. explodes
解析：上一句提到三手烟会与其他物质结合(combines with some substances)。空格后的dust属于其中一种，故B项mixes“混合”正确，对应上句中的combines一词。
4.【C4】(D)
A. rolls
B. circles
C. drops
D. drifts
解析：根据空格后down to carpeting(落到地毯上)，可推测此处是三手烟的运动方式和过程。一般来说，烟(雾)是飘散在空中，D项drifts“漂移”满足逻辑要求。
5.【C5】(A)
A. surfaces
B. structures
C. ornaments
D. textiles
解析：空格处的名词与carpeting一起作此分句中的宾语，表明Third hand smoke运动到的地方。对于家具(furniture)而言，它一般是附着在其表面，选A项surfaces。
6.【C6】(C)
A. resides
B. traps
C. lingers
D. sticks
解析：破折号后的句子说明：一个在室外吸烟的妈妈进门抱孩子时仍会将孩子暴露于三手烟中，由此可判断香烟中的有害物质会留在吸烟者的身上——头发、皮肤、衣服和指甲中。C项lingers“萦绕，徘徊，逗留”能满足语义要求。
7.【C7】(C)
A. since
B. though
C. so
D. provided
解析：破折号前的句子承接上文说明三手烟会出现在吸烟者的身上，空格后句子说明在外面吸烟的妈妈回到家里抱孩子其实是将孩子暴露于三手烟中。前后句子间存在一定的因果关系。故C项so符合要求。
8.【C8】(D)
A. far from
B. but for
C. with respect to
D. in front of
解析：从空格后的smokes outside(在外面吸烟)便可知道妈妈没有在孩子面前吸烟。D项in front of与doesn’t搭配，表明没有在孩子面前吸烟。
9.【C9】(B)
A. convenient
B. difficult
C. expensive
D. awful
解析：逗号后分句have a
