Sleep deprivation plays with our emotions







Anyone who's ever had a poor night's sleep knows they can be cranky than usual the next day. Now researchers think they know why that's so: there are strong neurological links between sleep and emotions.


Researcher Matthew Walker from the University of California at Berkeley asked a group of people to ________ for 35 hours at a stretch. Then he put his subjects in a brain- ________ machine while showing them photographs. The first photos were 'neutral': pictures of a leaf or of a basket. But as the parade of images continued, the pictures become more disturbing: such as photographs of a shark attack, or severed limbs.


Walker says that affected deep emotional centers of the brain, ________ a region called the amygdale. "The amygdale were actually up to 60 percent more reactive to those emotionally-negative pictures in those who hadn't had a good night of sleep compared to those who had," Walker says. "And that really is a profound amplified emotional brain reaction to these  ________ pictures."


Walker says scientists know that the amygdale is part of the brain in emotional  ________. But he says this level of amygdale activity in the tired subjects is similar to activity recorded in the amygdalas of people who have some psychiatric  ________ such as depression or post-traumatic stress disorder.


"It's actually very difficult to find a psychiatric disorder with emotional or mood symptoms that doesn't have impairments of sleep," asserts Walker. "And we've been  ________ with the battle between the chicken and egg question. Is it the psychiatric condition that's causing the sleep impairment, or is it the sleep impairment that's causing the psychiatric condition?" Walker says it's also possible to induce psychosis in a healthy person who's been denied sleep.


He speculates that one function of sleep is to restore the emotional circuits of the brain, and says we need to pay more attention to the emotional and mental health benefits of sleep. "And I also don't think it's a coincidence that many anti-depressant medications, for example, actually seem to alter sleep and try and  ________ sleep," he adds.


Walker says the next challenge is to determine what kind of sleep and how much is most important for maintaining emotional health. His research is published in the  ________ Current Biology.

unpunctual again.” Those who think in this way will find excus-


es for delay from time to time, and will at least give up the at-


tempt cultivating the good habit of punctuality. 80. ______


Like all other good habits, punctuality becomes second na-


ture with those who have duly cultivated it.




46. B chiefly是副词不影响核心结构,可忽略。本题考不定式表目的

47. A  句中it是形式主语,代替 that引导的主语从句。

48. A   do you think是插入语可忽略

49. C 在四个选项中只有the rest可以代替可数名词或不可数名词,其它三个只代替可数名词。上句work是不可数名词,所以答案是C.

50. B




71 permitted promised


permit作为动词,是“允许”的意思,常用于词组permit sb. to do sth.:允许某人做某事。根据上下文,此处应译为:“一个许诺下午五点钟拜访一位朋友,而事实上也做到了这一点的人是准时的”。这里所表达的意思是“许诺”,不是“允许”,应用promise,并且promise to do sth.是“许诺做某事”的意思,从语法上也符合。此句是易混词错误。

72 such so

suchso的共同点在于两者都是代词,都是“这样”的意思。区别在于such不能单独代替某成份,而so可以独立代替前文所提及的事。如此句中does such a thing = does so,但是does such却不符合语法。本句属于代词误用错误。

73 minutes minutes"


74 usually usual

usually是副词,意思是“通常地”。这里five minutes later than usual中的“… than usual”是固定搭配。usual的类似用法还有as usual(和平常一样)。这是固定搭配错误。

75 Call Calling/To call

本句主语是一个动词短语,但是动词短语做主语时,其中的动词只能用动名词或不定式的形式,因而把Call改成CallingTo call。此句属于非谓语动词错误。

76 Nevertheless Moreover


77 him be to

prove sb. to do sth.”是固定搭配,意思是“证明某人做某事”。原句缺少不定式标志to。这属于固定搭配的错误。 78 from of

get rid of”是固定搭配,意思是“摆脱”。用from是错误用法,应把它改成“of”。这属于固定搭配错误。

79 ever never


80 cultivating to cultivate

cultivate意思是“培养”,这里做名词attempt的定语。“attempt n. to do sth.”意思是“做某事的尝试/努力”,应用不定式做后置定语。此句属于非谓语动词错误。


stay up
