試題詳情
Nowadays，we can read almost all "truths"on social media sites．But are they really reliable？Sites such as the micro-messaging service Twitter，the social networking site Facebook and the photo-sharing app Instagram might "misrepresent the real world， " according to a study by computer scientists from McGill University and Carnegie Mellon University
The scientists warn that gathering information about public views and trends from these sites is unwise．There are still large parts of the population who do not take part in social media activities．Also，there's a risk that many social media users are under-represented．Instagram，for example，appeals to younger adults in urban areas while Pinterest is used mainly by females aged 25 to 34．And only 5 percent of Twitter users are over 65 years old，according to the study However，this is not the only issue，according to the scientific team．The design of a website can influence how people behave online，creating what the researchers call "Internet bias "For example，micro-blogging sites such as Weibo promote "popular" stories．It saves time for some but it also limits readers' choice of what they see．In the end，many people open those stories and make them more "popular " But it's not because they choose those stories．Rather，it is because the content is right in front of them．
Besides，it's possible that not everyone on your social networks is real．There might actually be a few fake accounts among them．Fake " bots" pretend to be human and are often included when measuring or predicting human behaviors online．
The findings might be more important than you would think，since many social media studies are used to inform and justify decisions and investments among the public and in industry an government， "said Derek Ruths，assistant Professor at McGill，a School of Computer Science．
If the team is right，you might have to think carefully the next time you say， "It's true，you know；I read it on Weibo．"

A．Because they are the best social media sites today．

2．Hi Judy!
You often complain to me that you always buy goods unreasonably on sale promotion（促銷）and feel it shameful after going back to your school dormitory with new things not needed，considering all the money you spend is your parents' income．
In fact，this is a common phenomenon，called impulsive buying，a buying unplanned and hard to control．It usually happens when a store offers discounts（打折）or sales promotion-a special way used by stores to get more customers，which means you may fall into its traps even without notice．
Stores，with a good knowledge of customers' psychology（心理），make use of it to drive business．Avoiding all the impulsive buying is a hard thing．However，knowing our psychology behind it and reducing the times when influenced by sales promotion may be useful．So you should keep calm when facing the sales promotion by keeping in mind what you really need．
Find out the conditions where you are likely to buy things blindly．When seeing a dress advertised at 20% off，do not concentrate on the discount，but warn yourself against falling into the trap of "saving money''．
Besides，do not forget the long-term effects of your choice when meeting a sales promotion．Short-term benefits，like excited feeling just after buying items encourage impulsive buying．But the long-term costs such as waste of money and the sense of shame really annoy you．When seeing the advertisements，remember what you really want to buy originally and warn yourself of that terrible feeling．Only in this way can you save money for really needed things．
Yours，
Rachel

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.
