19．Unlike chemists and physicists，who usually do their experiments using machines，biologists and medical researchers have to use living things like rats．But there are three Nobel prize-winning scientists who actually chose to experiment on themselves-all in the name of science，reported The Telegraph．
●Werner Forssmann （Nobel prize winner in 1956）
Forssmann was a German scientist．He studied how to put a pipe inside the heart to measure the pressure inside and decide whether a patient needs surgery （手术）．
Experiments had been done on horses before，so he wanted to try with human patients．But it was not permitted because the experiment was considered too dangerous．
Not giving up，Forssmann decided to experiment on himself．He anaesthetized （麻醉） his own arm and made a cut，putting the pipe 30centimeters into his vein （血管）．He then climbed two floors to the X-ray room before pushing the pipe all the way into his heart．
●Barry Marshall （Nobel prize winner in 2005）
Most doctors in the mid-20th century believed that gastritis was down to stress，spicy food or an unusually large amount of stomach acid （胃酸）．But in 1979an Australian scientist named Robin Warren found that the disease might be related to a bacteria （细菌） called Helicobacter pylori．So he teamed up with his colleague，Barry Marshall，to continue the study．When their request to experiment on patients was denied，Marshall bravely drank some of the bacteria．Five days later，he lost his appetite and soon was vomiting （呕吐） each morning-he indeed had gastritis．
●Ralph Steinman （Nobel prize winner in 2011）
This Canadian scientist discovered a new type of immune system cell （免疫细胞） called the dendritic cell．He believed that it had the ability to fight against cancer．
Steinman knew he couldn't yet use his method to treat patients．So in 2007，when doctors told him that he had cancer and that it was unlikely for him to live longer than a year，he saw an opportunity．
With the help of his colleagues，he gave himself three different vaccines （疫苗） based on his research and a total of eight experimental therapies （疗法）．Even though Steinman eventually died from his cancer，he lived four and a half years，much longer than doctors had said he would．

14．General Airport Tips
Plan to get to the airport at least an hour early，or two during holidays and other busy times； this will reduce the stress of the flight．If all goes well，you will have time to relax，shop for last-minute items，or have a meal before the flight．
Flight Delays
Find out why your flight is delayed．Call the free call numbers．Find out if other airlines are experiencing similar delays．If you believe the delay is due to something other than weather or air traffic problems，then mention your suspicion （怀疑） and ask the airline agent to book you on the next available flight，either on the same air-line or a competing one．This is called"Rule 240"，and all airlines are required to do it．Use the lingo （行话）； ask，"Can you 240me？"when speaking with an agent．They will know what you mean．
Flight Cancellations（取消）
If your flight is canceled，then make a reservation on the next flight to your destination．Usually，air-line officials will try to book everyone on their next flight out．Often they will put you on a competitor's next flight only if you request it．
Getting bumped（不能登机）
To avoid getting bumped，you must be at the loading gate at least 10minutes ahead of scheduled departure for a U．S．Flight，20minutes to/from Bahamas，Canada，and Mexico and 30to/from all other international points．You must be at the loading gate，not the airport entrance．
56．By arriving at the airport earlier，one canB．
A．get on the airplane immediately
B．reduce the pressure of the flight
C．have a good rest in the airplane
D．buy what he wants in the airport
57．If a person calls"Rule 240"，he wants toB．
A．make sure the time for the next plane
B．get a ticket for the next flight
C．know if other flights are also delayed
D．ask about the cause of the plane delay
58．People heading for Germany must be at the loading gate at leastC．
A.40minutes ahead of time
B.20minutes ahead of time
C.30minutes ahead of time
D.10minutes ahead of time
59．The purpose in writing this text is toD．
A．show us how to get on a plane
B．tell us what to do before and after a flight
C．put forward suggestions for a flight
D．give us advice on dealing with airlines．

1．WHEN there are some strangers in front of us，which of them will we trust？
According to a new study in the online PloS One （《公共科学图书馆•综合》），people make their decisions to trust others largely based on their faces．Your appearance can do a lot for you，especially if you are in the financial industry．The more trustworthy you look，the more likely people will buy what you're selling．
Researchers from Britain's University of Warwick Business School，University College London，and Dartmouth College，US，did a number of experiments．
The research team used computer software to make 40faces，from the least to the most trustworthy-looking．
The study said that the difference between a trustworthy face and one that isn't as trustworthy comes from features that look slightly angry or slightly happy，even when the face is at rest．However，a slightly happy face is more likely to be trusted．
Researchers gave participants some money and asked them which face they trusted to invest the money for them．Then researchers gave some good and bad information about the people with these faces，and asked the participants again whom they trusted．
The results showed that even if they got different information，the participants didn't change their choices．They were still more likely to invest their money with the more trustworthy-looking faces．
Chris Olivola，one of the study's authors，said in the University of Warwick's press release："It seems we are still willing to go with our own instincts （本能） about whether we think someone looks like we can trust them．The temptation （诱惑） to judge strangers by their faces is hard to resist．"

19．Recently some articles state that the word‘‘selfie"has become one of the most annoying words．But I'd like to offer

that maybe it is not so bad．The"selfie"is used to describe the self-taken photo，often from a smartphone．Women and men decorate their Facebook，Twitter，and Instagram accounts with these pictures，sometimes with puckered （翘起） lips or large smiles．In fact，the selfie has become so widely known that over 31million photos on Instagram are taken with the selfie．
Let's think about it．Someone takes about 10selfies each time they do，and they only end up posting one or two of those．They pick the one that makes them look the best．Isn't that beautiful？In that one picture，someone has given himself or herself confidence．Self-image is important．In society today，we are so often consumed with what society tells us is perfect．But maybe，with that one selfie，we feel that we fit that bill．We feel handsome，beautiful，confident，smart，happy and content．For that moment，everything bad or terrible that has ever happened to us is erased，because that smile or that pucker is what gives us the determination to love ourselves．
I saw a spoken word poem recently and the young man said：If I ask you what you love，the answers will most likely roll off your tongue．You love to read．You love to write．You love birds，music，your mom，your brother，your sister，your daughter，your best friend，your dog．How long do you think you could go on and on before you said"I love myself"？
That statement hit me like a ton of bricks．I've struggled with confidence all of my life．I still do．And in no way am I saying that taking a selfie is a gateway to that confidence．However，the selfie does deserve some credit for allowing individuals to express themselves．Pamela Rutledge agrees，stating，"There are many more photographs available now of real people than models．"
