一、每晚只需8个小时,睡眼过多非益事
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9 或10 个小时的人比睡8 个小时的人存在更多问题。
与8 小时睡眠者相比,每晚仅睡7 个小时的人则表示,他们在入睡及经过一夜睡眠后精力恢复方面有更多的麻烦。
Daniel Kripke 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 个小时。
他补充说,对于那些每晚睡8 个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 个小时的人比睡眠充足者,在特定时期内死亡的概率更高。
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,包括半夜惊醒、清晨早醒、无法重新入睡,以及白天疲劳影响日常工作等。
Kripke 发现每晚睡9 - 10 个小时的人比睡8 个小时的人更容易出现各类睡眠问题。
在一次访谈中,Kripke 注意到睡眠时间长的人夜间可能难以人眠,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。
"在床上花的时间过长,醒着的时间就会更多,这是理所当然的。

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:
“...blacksootmayberesponsiblefor25percentofobservedglobalwarmingoverthepastcentury.”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.E Hansencautioned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:
