答案与题解:
1.E第二段列举了睡眠时间多于或少于8小时而带来的多种sleepproblems。
2.B第四段阐述了长期睡眠不足所带来的严重后果。
3.A第五段介绍了Kripke的调查工具(tool)。

4.D第六段最后两句是:
“...onewaytohelpinsomniaistospendlesstimeinbed.”和“Itstandstoreasonthatifapersonspendstoolongatimeinbed,thenthey'llspend

5.F选择F的依据是第三段第一句。
原文是:
“...peoplewhowanttogetagoodnight'srestmaynotneedtosetasidemorethan8hoursanight.”
6.E选择E的依据是第六段第一句。
原文是:
"…peoplewhosleptbetween9and10hourseachnightweremorelikelytoreportexperiencingeachsleepproblemthanpeoplewhoslept8hours.”
7.A本题答案的依据是第五段第二句:
“Sleepproblemsincludedwakinginthemiddleofthenight,arisingearlyinthemorningandbeingunabletofallbacktosleep...”
8.C本题答案的依据是第四段:
“...onereportdemonstratedthatpeoplewhohabituallysleeplessthan7hourseachnighthaveahigherriskofdyingwithinafixedperiodthanpeoplewhosleepmore.”
译文:
每晚只需8小时,睡眠过多非益事
睡眠不足带来的危害已经广为人知,而一项新的研究表明睡眠过多同样会使人们产生不良后果。
圣地亚哥加利福尼亚大学的研究人员发现在入睡、保持睡眠等方面,每晚睡眠9或10小时的人比睡8小时的人存在更多问题。
而每晚仅睡7小时的人则表示,他们在入睡及休息后精力恢复程度上不及8小时睡眠者。
DanielKripke博士在《心身医学》杂志上报告的这些新发现表明,人们如果想晚上休息好,每天留给睡眠的时间只需8小时。
他补充说,对于那些每晚睡8小时以上的人们来说,考虑减少在床上度过的时间“也许是个好主意”。
不过他又提醒说这还需要进一步的研究证实。
以往的研究证明了长期睡眠缺乏的潜在危机。
有报告显示,睡眠经常少于7小时的人比睡
眠充足者,在特定时期内死亡的机率更高。
而在目前这份报告中,Kripke考评了一份1004名成年人参与反馈的睡眠调查问卷。
问卷内容涉及每周睡眠时间和各种可能的睡眠问题,包括半夜惊觉,清晨早醒,无法重新入睡,以及白天疲劳,影响日常工作等。
Kripke发现每晚9至10小时睡眠者比睡8小时的人更容易出现各类睡眠问题。
在次访谈中,Kripke注意到睡眠时间长的人夜间可能难以入眠,正是因为他们睡得太多了。
因此他补充说,治疗失眠最好的一种方法就是少睡点儿。
“在床上花得时间过长,醒着的时间就会更多,这是理所当然的。

答案与题解:
1.C第三段解释了为什么soot会增加地球升温效应。
2.A第四段介绍了soot在两方面起的作用:
(1)soot增加了雪吸收太阳能量和热量的能
力;
(2)soot导致海洋和陆地上空的大气层发生变化。
3.F第六段的关键句子是:
“...greenhousegasesaretheprimarycauseofclimatewarmingduringthepastcentury.”
4.B第七段介绍了在研究北半球的纬度、雪覆盖面和日照诸因素与气温升高之间的关系方面取得的成果。
5.B选择B的依据是第一段。
有关的句子是:
“...blacksootmayberesponsiblefor
25percentofobservedglobalwarmingoverthepastcentury.”选项B中用了过去式contributed,也是选B的一个线索,因为第五题的题干中有inthetwentiethcentury,这个时间状语要求谓语
动词用过去式,而4个选项中只有B项的动词用的是过去式。
6.EHansencautioned和greenhousegases仅出现在第六段。
该段的大意是:
虽然煤烟
在改变全球气候方面所起的作用相当显著,但是上个世纪气温上升的主要因素还是温室气体。
选项E
概括了第六段的意思。
7.D本题答案的依据是第二段第一句
8.A本题答案的依据是第五段的下列句子:
