Here's an idea whose time has come：A flu shot that doesn't require an actual shot．
For the first time，researchers have tested a flu vaccine patch （疫苗貼） in a human clinical trial and found that it delivered as much protection as a traditional injection with a needle．Doctors and public health experts have high hopes that it will increase the number of people who get immunized （免疫的） against the flu．
Seasonal flu is responsible for up to half a million deaths around the world each year according to the World Health Organization．A team led by Georgia Tech engineer Mark Prausnitz has come up with an alternative method that uses "microneedles"．These tiny needles are so small that 100 of them，arranged in order on a patch，can fit under your thumb （拇指）．Yet they're big enough to hold vaccine for three types of flu．
None of the study volunteers had serious side effects．The groups that got patches had mild skin reactions that were not seen in the regular needle group，while the volunteers in the regular needle group were more likely to experience pain．Overall，70 percent of the volunteers who got vaccine patches said they'd rather use them again than get a traditional flu shot．The study authors declared it a success on all fronts．
The biggest beneficiaries could be people in low-and-middle-income countries，where flu vaccines are hard to come by．Reducing pain is nice，but other benefits-the patch costs less，is easier to transport，doesn't require refrigeration，can be self-administered and doesn't cause waste of needles - are even better．
"Microneedle Patches have the potential to become ideal candidates for vaccination programs，" wrote Katja Hoschler and Maria Zambon of Public Health England．

2．The size of the British Isles often leads people to think that the languages spoken in its countries of England，Scotland，Wales and Northern Ireland are somewhat the same.At first，visitors are often surprised to find that they have difficulty in understanding the accents and dialects of certain regions.Even in England there are many different dialects.
Experts believe that for most English people，the places they come from are very important to them.Accents are clues to where people were born and where they grew up.Although some people may change the way they speak during their lifetime，most people carry at least some evidence of their accents and dialects throughout their lives.In addition to the regional accents of England，there can also be class differences among the accents.People are often able to make instant and unconscious judgments about a stranger's class by listening to his or her accent.Both the words and the pronunciation of an individual reflect his or her social position.
It is agreed that in England，the kind of English spoken by a person plays a leading role that generally is not important in North America.The importance of accents and their cultural and social relationships are well represented in films and on television in Britain.The film My Fair Lady based on George Bernard Shaw's 1912 play Pygmalion is often said to be a wonderful example of how social class and the accent were，and still are，linked in Britain.

3．Ever since I graduated from high school I've worked in the factories surrounding my hometown every summer.However，making the transformation between school and full-time blue-collar work during the break never gets any easier.For a student like me who considers any class before noon to be unacceptable，getting to a factory by 6 o'clock each morning is suffering.My friends never seem to understand why I'm so relieved to be back at school or that my summer vacation has been anything but a vacation.
There are few people as self-confident as a college student who has never been out in the real world.People of my age always seem to overestimate the value of their time and knowledge.In fact，all the classes did not prepare me for my battles with the machine I ran in the plant，which would jam whenever I absent-mindedly put in a part backward or upside down.
The most stressful thing about blue-collar life is knowing your job could disappear over night.Issues like being laid off and overseas relocation had always seemed distant to me until my co-workers told me that the unit I was working in would shut down within six months and move to Mexico，where people would work for 60 cents an hour.
After working 12-hour shifts（輪班）in a factory，the other options have become only too clear. "This job pays well，but it's hell on the body，" said one co-worker. "Study hard and keep reading." she added.When I'm back at the university，skipping classes and turning in lazy re-writes seems too irresponsible after seeing what I would be doing without school.All the advice and public-service announcements about the value of an education that used to sound stale（陳腐的）now ring true.
My experiences in the factories have inspired me to make the most of my college years before I enter the real world for good.

（2）What can we infer about most college students？
A．They do better in the real world.
B．They are confident when they work.
C．They think too highly of themselves.
D．They are expert at handling machines.
（3）What is the biggest pressure for blue-collar workers？

C．An unstable location.
D．Less break.
