11．If you get your news from social media，you are faced with a daily number of hoaxes（恶搞），rumors，and misleading news．When it's all mixed in with reliable information from honest sources，the truth can be very hard to judge．In face，my research team's analysis of data from Columbia University's Emergent rumor tracker suggests this false information is just as likely as to spread crazily as reliable information．
Our research shows that in view of the structure of our social networks and our limited attention，it is unavoidable that some popular unconfirmed information will spread quickly，regardless of their quality．Even if individuals tend to share information of higher quality，the networks as a whole is not effective at telling the difference between reliable and fake information．This helps explain all the hoaxes we observe in the wild．Besides，our attention is limited．If we pay attention to a certain topic，more information on the topic will be produced．It's cheaper to fake information and pass it off as fact than it is to report actual truth．
We can make our fight against false news more efficiently if we better understand how false information spreads．If，for example，robots are responsible for many pieces of the false news，we can focus attention on detecting them．
To that end，our lab is building a platform called Hoaxy to track and monitor the spread of unreliable information on social media．That will give us real-world data，with which we can inform our imitated social networks．Then we can test possible approaches to fight false news．Hoaxy may also be able to show people how easy it is their opinion to be misrepresent by online information and how likely some of us are to share false news online．Hoaxy will join a set of tools in our Observatory on Social Media，which allows anyone to see how false information spread on the Internet…
It is necessary that we spend resources on the study of this phenomenon．We need all hands on decks：Computer scientists，social scientists，economists，journalists and industry partners must work together to flight against the spread of false information．

19．Smoking bans in public places are linked with falls in childhood asthma （哮喘） attacks and preterm births （早产），according to the biggest analysis of the influence of public smoking bans on child health．The finding should remove fears that such laws could have the opposite effect because they may lead people to smoke more at home．
Several countries，such as Japan and Australia，have tightened laws on smoking in public places over the last few years．Meanwhile，some countries，such as the Netherlands and Germany，still allow smoking in pubs and restaurants．Only about half of US states have comprehensive bans，and there are few restrictions in poorer nations．
Opponents often claim that bans could result in people smoking more at home，which would be worse for their children's health．Asthma is one of the main concerns as second-hand smoke harms children's airways in several ways．
Researchers led by Jasper Been at Maastricht University Medical Centre reviewed as many as 11studies that examined how hospital admissions for childhood asthma and preterm births changed after smoking bans came in．The studies involved more than 2.5million births，and nearly 250，000hospital admissions for asthma．
The result shows that both asthma admissions and preterm birth rates fell by about 10percent within a year after smoking restrictions were carried out．The effect on preterm births could also have been caused by pregnant women being more likely to quit or cut down following a public ban，says Been．But Been also says the studies could not completely prove that smoking bans directly caused these changes．However，as a matter of fact，because the analysis included several smoking bans introduced in different countries in different years，and most saw health improvements．
Such findings are useful for countries and states where there is ongoing debate about how strict smoking bans should be，especially as hospital care for premature babies is so expensive．This might be one of the most important things to know in order to strengthen legislation （立法）．
Other studies have shown that rates of heart attack and stroke also tend to fall after smoking bans are introduced．
21．According to the passage，some oppose smoking bans in public places becauseB．
A．they have much difficulty in quitting smoking
B．they believe it will cause people to smoke more at home
C．smoking bans contributing to health can't be proved
D．the laws might cause opposite effect on smokers
22．Which is NOT the proper effect of the result of research by Jasper Been？C
A．People would accept the laws on smoking bans in public places．
B．More and more countries and states will strengthen smoking bans．
C．Hospital care for premature babies and asthma will be cheaper．
D．Pregnant women will be more likely to follow public smoking bans．
23．Which of the following statements about Been's research is TRUE？D
A．It also proves smoking bans lead to falls of heart attack and stroke．
B．It is related to millions of asthma hospital admissions and births cases．
C．It offers conclusive evidence about smoking bans causing health benefits．
D．It is supposed to prove the effect of smoking bans in public places on health．
24．In their analysis，the researchers drew their conclusion byA．

17．Because，like most of you，I began college in my teens，but the second year，I was offered my dream job at Universal Studios，so I dropped out．
Well，I left college because I knew exactly what I wanted to do，and some of you know，too-but some of you don't．Or maybe you thought you knew but are now questioning that choice．Maybe you're sitting there trying to figure out how to tell your parents that you want to be a doctor and not a comedy writer．
I told my parents if my movie career didn't go well，I'd re-enroll．It went all right．But eventually，I returned for one big reason．
Most people go to college for an education，and some go for their parents，but I went for my kids．I'm the father of seven，and I Kept insisting on the importance of going to college，but I hadn't walked the walk．So，in my fifties，I re-enrolled at Cal State-Long Beach，and I earned my degree．
Well，what you choose to do next is what we call in the movies the'character-defining moment．'
Life is one strong，long string of character-defining moments．And I was lucky that at 18I knew what I exactly wanted to do．But I didn't know who I was．How could I？And how could any of us？Because for the first 25years of our lives，we are trained to listen to voices that are not our own．Parents and professors fill our heads with wisdom and information，and then employers and mentors （有经验的顾问）take their place and explain how this world really works．
And I want to be clear that your intuition（直觉） is different from your conscience．They work together，but here's the distinction：Your conscience shouts，"here's what you should do，"while your intuition whispers，"here's what you could do．"Listen to that voice that tells you what you could do．Nothing will define your character more than that．
