答案与题解：
- F8 K, q1 Q5 G1．B  本文的重点是介绍借抽烟缓解抑郁情绪的青少年到后来他们的depressive symptoms (抑郁症状)反而加重了。第二、第五、第六段都明确提到这一点。所以B(increase)是答案。其他三个选项的词义与上下文的意思搭不上。
2．C抽烟缓解抑郁是一种情绪上(emotional)的得益，不会是social(社会上的)、financial(经济上的)或political(政治上的)得益。所以答案是Co
3．B空格所在的句子虽然缺字，意思还是清楚的，前半旬的意思与后半句的意思是相反的。前半句说香烟看上去有助于改善心情，后半句说从长远角度看，depressive symptoms的风险反而会增加。四个选项中只有选项8的Although能将前半句和后半句连接起来，并赋
予“让步"的意思。
! k; i) E" n$ x! ]4．A句中的or是“即”，也就是说，to have self-medicatin9加上填入的词之后的意思相当于to improve mood。四个选项中只有选项A的effects(效果)是填入空格的最合适的词。toimprove mood是自我治疗的效果。其他三个选项methods、steps、directions与self-medicatin9连用，意思分别为“自我治疗的方法”、“自我治疗的步骤"、“自我治疗的指导"，与句子的意思不相配。
, `. O% K0 Z% ^7 s5．D  本题要填入的词是介词。分析下来，their use of cigarettes to affect mood应该是questionnaire(问卷)所要了解的内容。所以，about是正确的选择。
6．C科学家在选择问卷对象时注意了代表性，入选的青少年既有讲法语的，也有讲英语的，他们就读的学校有城市的，也有农村的。接下来的问题是：在schools和in high，moderateand low socioeconomic neighbourhoods(高档社区、中档社区和低档社区)之间选哪个词才符合上下文的意思呢?很明显，这些学校有位于高档社区的，也有位于中档和低档社区的。所以选项C的located是答案o
7．A本句的意思很明显，问卷的参与者被分成三组或三类。9roups是正确的选择。再看其他三个选项：three sets是“三套"，three species是“三个物种”，three versions是“三个版本"，没有一个是合适的。
8．C科学家将参与者分成三组，其中一组的参与者不采用吸烟作为自我调节情绪的手段。填入的词应与情绪、身体等有关。若选A、B、D，组成的词组physical world(物质世界)、physical activity(体育活动)、physical beauty(形态美)均与上文的意思接不上，所以A、B、D不会是答案。由C的state组成的词组physical state(身体状况)与上文的意思连贯。因此C是答案。
9．D本段介绍了问卷包含的问题。作者罗列的问题都是负面的，如乏力、失眠、烦躁等。所以填入空格的词也应该是负面的。trouble符合这个要求，是本题的答案。
" R( X4 D/ f! n4 ^' G+ y/ z10．A  第九题选了trouble，空格所在的句子是“…had trouble going to sleep or staying
”。or是“即”的意思，也就是说，had trouble going to sleep意思上就相当于staying_____。根据这一判断，填入空格的词非awake莫属。
2 t3 l- l$ O& G  [5 r11．B第一段和第二段都说到，抽烟缓解抑郁心情最终导致更抑郁。本句“Smokers who used
  H' v) H! ]; g3 t) G1 F2 qcigarettes as mood had higher risks of elevated depressive symptoms than teens who had never smoked”表达的是同样的意思。文章第二段和第三段都出现improve mood，所以，mood后面要填入的词应该是improvers0选项A、C、D的意义均不符合上下文o
$ |" z4 k6 D6 t0 A. t. x6 L. l12．C本句又重复了上题所表达的意思。只有developin9的意义才符合上下文，因此是答案。
7 R2 V, E. I' C4 S13．B从上下文判断，本句指的是depression和smokin9之间的联系，不会是它们之间的差异。(difference)、合作(cooperation)或一致性(agreement)。association的词义是“联系”，所以是答案。
3 ?7 R& e" f# F8 W( p+ U3 s14．D调查的对象是青少年，所以不可能是0ccasionally(偶尔)、scarcely(几乎不)或probably。(很可能)在青少年之中，而是principally(主要)在青少年之中。
. k& e- W+ ^( v" V1 5．D  从通篇文章判断，“to emphasize that depressive symptom scores were higher amongteenagers who reported emotional benefits from smoking after they began to smoke”是做这项调查的发现和结论，作者说出这一点，只会认为很重要(important)，不会认为不合乎逻辑 (illogical)，不科学(unscientific)或没有意义(meaningless)。所以，important是答案。
