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 thatcaters to the late-nighter, from 24-hour grocery stores to online shoppingsites that never close. It’s no surprise, then, that more than half of Americanadults don’t get the 7 to 9 hours of shut-eye every night as recommended bysleep 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 whileit isn’t ideal, it might help. When Liu, the UCLA sleep researcher andprofessor of medicine, brought chronically sleep-restricted people into the labfor a weekend of sleep during which they logged about 10 hours per night, theyshowed improvements in the ability of insulin to process blood sugar. Thatsuggests that catch-up sleep may undo some but not all of the damage that sleepdeprivation causes, which is encouraging given how many adults don’t get thehours they need each night. Still, Liu isn’t ready to endorse the habit ofsleeping less and making up for it later.  

Sleeping pills, while helpful for some, are not necessarily a silverbullet either. “A sleeping pill will target one area of the brain, but there’snever going to be a perfect sleeping pill, because you couldn’t reallyreplicate the different chemicals moving in and out of different parts of thebrain 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aculture，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 dosth.”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…”。
