16．Tricks to Learn from Super SleepersDo you want to sleep soundly each night and wake up energized the next day？
Exercise early．
Morning fitness class（健身班） or gym time before work？Go ahead，give it a try．（31）FWhile experts aren't exactly sure why，it could have something to do with morning exercise's ability to help regulate the secretion（分泌物） of certain hormones（荷尔蒙） involved in blood pressure management，which may lead to better sleep．
Eat light at night．
Desiring a midnight snack？If your stomach starts rumbling（发出咕噜声） before bed，try reaching for good-for-you foods that actually promote sleep，like walnuts，tart cherries，or Greek yogurt instead． （32）D Eating too much of anything within a few hours of going to bed could suppress（抑制） your body's ability to produce sleep-promoting melatonin．
Power down at night．
Smart phones，tablets，and laptops let you do everything from shopping to watching movies to working in bed．What they don't let you do？Fall asleep．（33）G．In addition to reducing your blue light exposure，you'll probably feel less stressed，which in itself can help you sleep better．
Keep their rooms cool
 （34）A But being too warm can make it harder to have quality sleep，say experts at the National Sleep Foundation．Instead，they recommend keeping your bedroom at around 20℃，which research suggests is the most suitable temperature for great sleep．
（35）C
Consistency（一致性） is key to healthy sleep．Though for some it's usual to stay up late，then get up early for work and sleep late on the weekends，doing so can cause damage to your body's internal clock．Over time，that can make it harder to fall asleep，not to mention making it more unpleasant to wake up in the morning．

A．The idea of a comfortable bedroom and piles of soft，fuzzy（毛茸茸的）blankets is very appealing．
B．Find ways to deal with stress．
C．Go to bed at the same time every night．
D．However，try not to overeat even it is the healthy food．
E．You don't have to give up alcohol altogether in the name of better sleep．
F．Exercising in the morning could lead to better sleep than afternoon or evening sweat sessions．
G．Put your devices away at night-ideally，two to three hours before you plan to go to sleep．

6．Alone But Not Lonely
    In today's fast-paced society，we've become uncomfortable with silence．We try to find different types of activities that can help us escape feelings of laziness or boredom．（36）DSolitude（独处）does not have to be uncomfortable or lonely．In fact，solitude and loneliness are very different things．
    The death of a loved one or the inability to find people who understand you can leave you feeling lonely．Even if you are surrounded by other people，it's natural to experience an emptiness while longing for love or acceptance．（37）AGeoffrey F．Fisher once said，"In cities，no one is quiet but many are lonely．（38）E"
    We often fill loneliness with all types of unsatisfying activities．Young people would rather spend a Friday night out with strangers than spend the night alone．They're looking for a way to kill time while they await true friendship．Then there are young adults in gangs where they don't really like their companions．（39）BWhy does being alone scare us？
    Do not be afraid of silence．（40）FIt teaches you how to truly listen．It teaches you to pay attention to what's going on inside of you．Only when we are alone can we have the space and peace we need to think without being outwardly influenced．It therefore becomes easier to make important decisions as well as to reflect on how we are feeling．

A．Loneliness is therefore a feeling that can be experienced whether or not one is physically alone．
B．They would rather feel accepted on a shallow level than risk feeling alone．
C．The problem of loneliness can be easily solved in a modern world．

It took more than 20years for the Taj Mahal to be built．Workers were brought in，not only from all over India，but from Central Asia too．（18）B

（19）A As it is built with white marble stones，its character changes in different lights．It looks more beautiful at sunrise and sunset．At sunset，for example，the color of the Taj changes from white to yellow，then to pink．（20）F
