Ride-sharing services are thought to help to reduce pollution since fewer people use private vehicles and cause carbon dioxide.However，a new study has found that these services result in much more pollution than other kinds of private and public transportation.Ride-sharing trips also draw passengers away from more environmentally-friendly methods of travel，like public transportation，walking or biking，the study found.
Several studies in recent years have suggested that ride-sharing services like Uber and Lyft can worsen traffic problems in cities，which continue to have high rates of private vehicle ownership.
The new study，carried out by the nonprofit group Union of Concerned Scientists，represents an attempt to center on how ride-sharing services affect pollution.The research examined the effects of ride-sharing services on seven of America's largest cities.Overall，the researchers reported that ride-sharing trips now "result in about 69 percent more climate pollution on average than the trips they replace".The study notes that the same passengers could have chosen to travel by bus，train，bike，scooter（小型摩托車）or on foot.
One of the big reasons they give for this result is that ride-sharing vehicles are often driven with no passengers in the car.This happens when drivers are either waiting for rider requests，are on the way to pick up passengers or are driving between pickups.
This situation，known as"deadheading" takes up about 42 percent of the ride-sharing driving activity，the study found.The researchers said that "deadheading" results in about 50 percent more carbon dioxide than one person driving in a private vehicle.
The study urges services like Uber and Lyft to increase the number of electric vehicles on the road and to improve connections to public transportation centers.The two companies already operate businesses that offer electric scooters and bikes and have begun to include public transportation information in their systems.In some cities，they have also promoted vehicle electrification.

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.
