Ⅶ.阅读理解
It’s 3 o’clock and you’ve been hard at work.As you sit at your desk，a strong desire for chocolate overcomes you.You try to busy yourself to make it go away.But it doesn’t.Here is another situation.Perhaps you are not feeling well.The only thing you want to eat is a big bowl of chicken soup，like your mom used to make when you were sick as a child.Food cravings are a strong desire for a specific type of food.And they are normal.
Scientists at the website How Stuff Works compare hunger and cravings this way.Hunger is a fairly simple connection between the stomach and the brain.They even call it simply “stomach hunger”．When our stomachs burn up all of the food we have eaten，a hormone(荷尔蒙) sends a message to one part of the brain for more food，which regulates our most basic body functions such as thirst，hunger and sleep.The brain then produces a chemical to start the appetite and you eat.Hunger is a function of survival.
A craving is more complex.It activates(使活跃) brain areas related to emotion，memory and reward.These are the same areas of the brain activated during drug­craving studies.So，some scientists call food cravings “mind hunger”．People often crave foods that are high in fat and sugar.Foods that are high in fat or high in sugar produce chemicals in the brain.These chemicals give us feelings of pleasure.
In a 2007 study，researchers at Cambridge University found that “dieting or restricted eating generally increases the possibility of food craving”．So，the more you deny yourself a food that you want，the more you may crave it.However，fasting is a bit different.They found that eating no food at all for a short period of time lessened food cravings.
So，the next time you crave something very specific，know that your brain may be more to blame than your stomach.

Ⅷ.七选五
Do you feel a little guilty about your daily nap(小睡) after lunch? Don’t.Research shows that catching a short nap can be good for your brain. 1
While a 30­to­90­minute nap in older adults appears to have brain benefits，anything longer than an hour and a half may create problems with cognition(认知)，the ability to think and form memories，according to the study published in the Journal of the American Geriatrics Society.
“ 2 But it is related to one’s sleep cycles and quality，” says Charlene Gamaldo，M.D.，medical director of Johns Hopkins Sleep Disorders Center.“As the study showed，for older people，longer naps tend to interfere(妨碍) with cognition，” she says.
3 Nearly 60 percent of participants reported napping after lunch for about an hour.Scientists found that people who napped for 20 to 90 minutes have a better memory than people who did not nap，or who napped for longer than 90 minutes.People who napped for 30 to 90 minutes were also better at figure drawing，another sign of good cognition.
One theory explains poor cognition in those who take longer naps. 4 “In the study，naps longer than 90 minutes could have been called ‘a second sleep’．This poor quality nighttime sleep，which requires extra­long napping during the day，can lead to cognitive problems，” Gamaldo adds.
According to Gamaldo，longer naps can cause a couple of other problems，including temporary grogginess(眩晕无力) and inability to sleep at night.
5 As a result，“People need to get the right quantity and quality of rest，” says Gamaldo.
A．I consider napping to be a good thing.
B．But it is the length of your nap that matters.
C．Generally speaking，the older one gets，the longer naps one needs.
D．Researchers looked at data from 2,974 people in China aged 65 and older.
E．Resting more during the day may be a sign of poor quality nighttime sleep.
F．Taking long naps during the day makes it difficult for one to fall asleep at night.
G．Overall，studies show that people who sleep too much or too little may have poor health.

1．答案　B
解析　上文肯定了小睡的好处；根据第二段内容可知，小睡的长度对人体有不同的影响，所以选B(但是取决于你小睡的长度)。
2．答案　A
解析　由下文“But it is related to one’s sleep cycles and quality...”中的But可知，此处作者肯定了小睡是好事，但是与睡眠周期和质量相关。故选A(我认为小睡是一件好事情)。
3．答案　D
解析　根据下文提到的一些具体的数据及调查结果可知，选D。
4．答案　E
解析　根据下文的“This poor quality nighttime sleep，which requires extra­long napping during the day...”可知，白天休息的多是晚上睡眠质量差的信号之一。故选E。
5．答案　G
解析　由下文“As a result，‘People need to get the right quantity and quality of rest，’ says Gamaldo.”可知，此处是作者得出的结论，故选G(总的来说，研究表明人们睡得太多或者睡得太少，都可能对身体不好)。
