1.【C1】
M
解析：空格作名词vision的定语，可能是名词、形容词或分词。本句提到睡眠不足引发的问题，blurred符合句意，表示睡眠不足可以导致“视力模糊”。
2.【C2】
B
解析：若sleep为句子主语，空格应为副词，“睡眠容易导致暴饮暴食”句意不通。因此空格应为名词，与sleep一起作句子主语，表示某种睡眠问题。空格所在句的上下文都是讲睡眠不足，deprivation“缺乏”符合句意。
3.【C3】
A
解析：填入空格的词可为动词、分词或形容词，与make sb．构成“使役动词+宾语+宾语补足语”结构。本句解释睡眠不足导致暴饮暴食的原因，即难以抵制食物的诱惑。vulnerable“易受攻击的”可与介词to搭配，符合句意。
4.【C4】
G
解析：空格在系动词和形容词之间，应为副词。remarkably符合句意，指出睡眠不足时，大脑的奖励中枢会变得“非常”活跃，使人容易受碳水化合物和脂肪的吸引。
5.【C5】
F
解析：定语从句中的that指代the exact point of sleeplessness，可见空格应为动词第三人称单数，作从句谓语。根据句意“研究人员并不知道睡不着到什么程度才会……人们吃披萨饼、巧克力或其他食物的欲望”，triggers“触发，引起”符合语义。
6.【C6】
K
解析：空格处需填入定语，修饰individual differences“个体差异”。本句是对上一句的补充，说明研究人员搞不明白的原因是个体差异“很大”，此处应选tremendous。
7.【C7】
H
解析：could表明此处应填入动词原形，且能与to搭配。空格后的to anyone who…and to people who…提示，专家认为这些研究结果对很多人都适用，apply“适用”符合句意。
8.【C8】
I
解析：空格应填入动词，作定语从句的谓语。空格所在部分意为：也适用于那些……失眠或睡眠障碍的人。suffer符合句意，suffer from意为“患(某种疾病)，为……所折磨”。
9.【C9】
C
解析：空格需填入名词、形容词或分词作amount的定语。根据句中的“多吃200-500以上卡路里”可知，此处是说这些人经常没有适量的睡眠，optimum“最合适的”符合句意。
10.【C10】
E
解析：空格应填入动词原形作谓语。下文提到，在睡眠时间少于6．5小时或6小时的情况下，你更需要的是睡觉而不是锻炼。可见，空格所在句是问：在睡眠不足的情况下还需不需要“找”时间做运动?squeeze\\

Five Myths about College Debt
[A]The trillion-dollar student debt burden has caused many debates about the value of college. Some argue that we educate too many young people. Indeed, average tuition costs have gone up faster than the rate of inflation. The cost of college today is, in inflation-adjusted terms, roughly double what it was in 1980. This creates legitimate concerns about the continued affordability of a college education.
[B]But the debaters often have their facts wrong. Very few Americans graduate with $100,000 in debt; college makes more sense today than ever; and no, our universities aren\’t blowing their money to fund college dorms and football stadiums.
Myth 1: The financial return for going to college is less now than it used to be.
[C]If anything, the value of an investment in college is higher now than it\’s ever been. The college premium(the difference between the earnings of college graduates and high school graduates)is at its highest level ever.
[D]It is true that in the years since the Great Recession, wages for recent college graduates have declined about 5 percent, but wages for those without a college degree have declined more than twice that, between 10 and 12 percent
