7．A new study has found that social media could be affecting the sleep of young adults．The study is a project of researchers at the University of Pittsburgh's School of Medicine．They found that young people who often use social media are more likely to suffer from sleep disorders than those who use social media less．
The researchers say doctors should ask young adults about their use of social media when treating sleep issues．"This is one of the first pieces of evidence that social media use really can affect your sleep，"said Jessica C．Levenson．She is a postdoctoral researcher in the university's Department of Psychiatry．She was the lead author of a report on the study．The researchers set out to examine the connection between social media use and sleep among young adults．
The researchers wanted to find out how often young people used social media sites like Facebook，Twitter and etc..For the study，they gave questionnaires to nearly 1，800adults，aged 19to 32．On average，members of the study group used social media sites one hour a day．They also visited various social media accounts 30times per week．Thirty percent of the study's participants reported having serious problems with sleeping．Those people who used social media a lot were three times more likely to have a sleep disorder．And those who spent the most time on social media were two times as likely to suffer from sleep disturbances．
Frequent checking is big part of the problem．Levenson said the number of times a person visits social media is a better predictor of sleep problems than overall time spent on social media．If this is true，she adds，then practices that stop such behaviors may be most effective．
Researchers say social media can influence sleep patterns in a number of ways．People can lose sleep by staying up too late looking at social media．Sensitive issues argued about on social media can cause"emotional，cognitive or physiological"excitement．Using an electronic device can disturb a body's natural sleep rhythms because of the light coming from cell phones or computer screens．The researchers note that in some cases，young adults who have a hard time sleeping may use social media to help them fall asleep．
"It also may be that both of these hypotheses （假定） are true，"says Brian A．Primack．He is director of the Center for Research on Media，Technology and Health．He is also the study's senior author．Primack says，"Difficult sleeping may lead to increased use of social media，which may in turn lead to more problems sleeping．This cycle may be particularly problematic with social media．Many forms of social media involve interactive screen time that is stimulating （刺激） and rewarding and，for those reasons，can keep you awake．"

68．From the results of the questionnaire，who are more likely to have a sleep problem？B
A．The participants aged from 19to 32．
B．The participants visiting social media frequently．
C．The participants using social media sites one hour a day．
D．The participants spending the most time on social media．
69．The main purpose of the passage is toC．
A．compare and evaluate
B．examine and reason
C．inform and explain
D．a(chǎn)rgue and conclude
70．What is the best title for the passage？A
A．Social Media Is Keeping Young Adults Awake
B．Difficult Sleeping Is Affecting Sleeping Patterns
C．Electric Devices Are Influencing Sleep Rhythms
D．Young Adults Are Suffering from Sleep Disorders．

9．An egg sinks to the bottom if you drop it into a glass of ordinary drinking water but what happens if you add salt？The results arc very interesting and can teach you some fun facts about density（密度）．
     What you'll  need：
*One egg*Water*Salt*A tall drinking glass
     Instructions：
     Pour water into the glass until it is about half full．
      Mix in lots of salt （about 6 tablespoons）．
     Carefully pour in plain water until the glass-is nearly full （be careful not to mix the salt water with the plain water）．
     Gently lower the egg into the water and watch what happens．
     What's happening？
      Salt water is denser than ordinary tap water．The denser the liquid is，the easier it is for an object to float in it．When you lower the egg into the liquid it drops through the normal tap water until it reaches the salt water，at this point the water is dense enough for the egg to float．If you were careful when you added the tap water to the salt water，they will not have mixed，enabling the egg to amazingly float in the middle of the glass．
 
21．Which of the following is the CORRECT order？B
①Mix in lots of．salt．
②Gently lower the egg into the water．
③Carefully pour in plain water until the glass is nearly full．
④Pour water into the glass until it is about half full．
A．④②①③B．④①③②C．①④③②D．③④①②

A．It will float in the water．
C．Nothing will happen．
B．It will sink to the bottom．
D．The result is not known．
23．Why can the egg float in the water according to the passage？C
A．Because ordinary tap water is denser than salt water．
B．Because ordinary tap water is as dense as salt water．
C．Because'the denser the liquid is，the easier it is for an object to float in it．
D．Because the more the liquid there is，the easier it is for an object to float in it．

18．Sharing a room with a family member or a friend can be tough，but it becomes especially difficult when you are sharing it with someone you hardly know．If you find yourself in a similar situation，do not worry．There are things you can do to help you deal with having a roommate，no matter who it may be．
First of all，you have to remember that you get what you give．If you are nice to others，then others will be nice to you as well．You also need to set personal space for yourself and for the other person．So before your new roommate moves in，talk to him．Set the rules early and discuss your hopes．
Remember that there are two things that make up any good relationship：belief and respect．The same thing applies to having a roommate．You have to respect each other．So he has that new PS3game that you've always wanted to try out？Ask permission first．If he says no，don't ask him for it again．If he lets you borrow his stuff，take care of the item and treat it as if it were your own．Make sure that you return it in the same condition as when you borrowed it．
To keep away from disagreement over who does the housework，clean as you go．For housework that can be shared，you may want to divide it equally so that you don't do all of it．Take turns in washing the dishes．You may do it every other day or you may divide the task so that you only have to do it in the morning and your roommate will only have to do it at night．
     When it comes to food and grocery items，determine what can be shared．Don't be too mean when it comes to sharing food．On the other hand，determine what you can share and what you can't and be clear about it．The advantages of sharing food is that both of you can save on time and food preparation．
25．What is the passage mainly about？D
A．Why you need a roommate．
B．How you drive a roommate you don't like．
C．What you do to find a roommate．
D．How you can get along with your roommate．
26．Good relationship among roommates lies in（在于）C．
A．money and gifts                         
B．a(chǎn)ttraction and good words
C．trust and respect                         
D．threats and orders
27．Which of the following is NOT true if you want to use your roommate's stuff？B
A．You must ask his or her permission first．
B．If your roommate doesn't lend you anything，try to take it．
C．If he or she lends the stuff to you，you must take care of it．
D．When you return the stuff you borrowed，it should be the same as before．
28．What can be inferred from the fourth paragraph？D
A．There are always quarrels between roommates．
B．Try to do all the housework by yourself．
C．Share everything with your roommates．
D．Try to do the housework by turns．
