New international research reveals the far-reaching impacts of forest cover loss on global biodiversity.The study，led by the University of Edinburgh and the University of St.Andrews，investigated the impacts of forest loss on species and biodiversity over time and around the world，revealing both losses and gains in species.
Focusing on biodiversity data spanning（跨越）150 years and over 6，000 locations，the study，published in Science，reveals that as tree cover is lost，plants and animals are responding to the transformation of their natural habitats.
Bringing together over 5 million records of the numbers of different plants and animals with information on both historic and contemporary peaks in forest loss，the researchers discovered both immediate and delayed effects of forest loss on ecosystems.
The pace at which biodiversity responds to forest loss varies from a few years，as is the case for light-loving plants and insects，to decades for long-living trees and larger birds and mammals.Gergana Daskalova，a Ph.D.student in the School of GeoSciences at the University of Edinburgh and lead author of the study，said， "Changes in the biodiversity of the planet?'s forests matter because they will reflect how these landscapes look，the types of species they support and the benefits that forests provide for society like clean air and water.?"
Maria Dornelas，a co-senior author from the School of Biology at the University of St.Andrews，continued，"Humans are undoubtedly changing the planet.Yet，global analyses of how biodiversity is changing over time are revealing biodiversity changes are nuanced（有細微差別的） and variable."
She added， "With a better understanding of the different ways，both positive and negative，in which forest loss influences biodiversity，we can improve future conservation and restoration of global ecosystems."

1．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.
