As it is， sleep is so undervalued that getting
by on fewer hours has become a badge of honor。 Plus， we live in a culture that
caters to the late-nighter， from 24-hour grocery stores to online shopping
sites that never close。 It’s no surprise， then， that more than half of American
adults don’t get the 7 to 9 hours of shut-eye every night as recommended by
sleep experts。
Whether or not we can catch up on sleep–on the weekend， say–is a hotly
debated topic among sleep researchers； the latest evidence suggests that while
it isn’t ideal， it might help。 When Liu， the UCLA sleep researcher and
professor of medicine， brought chronically sleep-restricted people into the lab
for a weekend of sleep during which they logged about 10 hours per night， they
showed improvements in the ability of insulin to process blood sugar。 That
suggests that catch-up sleep may undo some but not all of the damage that sleep
deprivation causes， which is encouraging given how many adults don’t get the
hours they need each night。 Still， Liu isn’t ready to endorse the habit of
sleeping less and making up for it later。
Sleeping pills， while helpful for some， are not necessarily a silver
bullet either。 “A sleeping pill will target one area of the brain， but there’s
never going to be a perfect sleeping pill， because you couldn’t really
replicate the different chemicals moving in and out of different parts of the
brain to go through the different stages of sleep，” says Dr。 Nancy Collop，
director of the Emory University Sleep Center。
36。 B。 caters 空格左是定语从句引导词that，并且that指代的是前面的a
culture，所以空格内应该填一个第三人称单数形式的动词与介词to搭配。cater to表示“迎合”，原句译为：“另外，我们生活在一个迎合着晚睡者的文化里，从24小时营业的杂货店到线上售货店都从不关门。”
37。 M。 recommended 空格左是as，右边是介词by，推测空格内应该填一个动词的过去分词形式，结合语义，7到9小时睡眠应该是专家XX的，所以选择“推荐”。
38。 D。 debated 空格左边有hotly，右边为topic，空格内应填一个形容词，理解为“热烈地xxx的话题”，结合语义，故选“被讨论的”
39。 F。 ideal 空格与左边的it isn’t共同构成主系表结构，空格内一般选择形容词或带冠词的名词，结合。。。while。。。might help。 理解为“尽管它是xxx的，它仍然是有用的”，所以选”理想的”，符合语境。
40。 C。 chronically brought为谓语，空格右边是形容词，空格内应该填副词修饰右边的形容词。结合语义，选“长期地”来修饰“失眠的人”。
41。 G。 improvements 空格左边直接就是谓语show，空格内极有可能是一个复数名词，而且“进步”也符合原意。
42。 E。 deprivation that引导一个定语从句修饰the damage，
翻译成睡眠xxx导致的破坏，所以sleep后面应该接一个名词，选E组成“睡眠匮乏”符合语境。
43。 L。 ready 根据“isn’t xxx to do
sth。”表示“不…去做某事”，推测出空格内填一个形容词，选ready表示“Liu尚未准备好去接受这个习惯，少睡一些晚点再补觉的习惯”。
44。 H。 necessarily 空格所在句为主系表结构，不缺主要成分，所以空格内应该填一个副词修饰be动词，结合，选“必须地”符合语境，“尽管安眠药对于一些人是有效的，但并不一定是一个有效的解决良方”。
45。 O。 target 情态动词will后面一定是一个动词原形，只有target符合，表示“一片安眠药会瞄准大脑的一个区域…”。

来源：Who Killed the Nokia Phone？
It seems to be a law in the technology industry that leading companies eventually lose their positions – often quickly and brutally。 Mobile-phone champion Nokia， one of Europe’s biggest technology success stories， was no exception， losing its market share in the space of just a few years。 Can the industry’s new champions， Apple and Google – not to mention titans in other tech sectors – avoid Nokia’s fate？
In 2007， Nokia accounted for more than 40% of mobile-phone sales worldwide。 But
consumers’ preferences were already shifting toward touch-screen smartphones。 With the introduction of Apple’s iPhone in the middle of that year， Nokia’s market share shrunk rapidly and revenue plummeted。 By the end of 2013， Nokia had sold its phone business to Microsoft。
What sealed Nokia’s fate was a series of decisions made by Stephen Elop in his
position as CEO， which he assumed in October 2010。 Each day that Elop spent at Nokia’s helm， the company’s market value declined by �18 million （$23 million） – making him， by the numbers， one of the worst CEOs in history。
But Elop was not the only person at fault。 Nokia’s board resisted change， making it impossible for the company to adapt to rapid shifts in the industry。 Most notably， Jorma Ollila， who had led Nokia’s transition from an industrial conglomerate to a technology giant， was too enamored with the company’s previous success to recognize the change that was needed to sustain its competitiveness。
The company also embarked on a desperate cost-cutting program， which included the
elimination of thousands of jobs。 This contributed to the deterioration of the company’s once-spirited culture， which had motivated employees to take risks and make miracles。 Good leaders left the company， taking Nokia’s sense of vision and direction with them。 Not surprising， much of Nokia’s most valuable design and programming talent left as well。
