1．Yellow is usually the color of happy，joyful emotions （情感）．But according to a new study，not all people associate the sunshiny shade with good feelings．
   To find out what factors might play a role，researchers tested a new hypothesis （假設(shè)）：What if people's physical surroundings affect their feelings about certain colors？For example，if someone lived in cold and rainy Finland，would they feel differently about the color yellow from someone who lived near the Sahara Desert？
   The researchers looked at color-emotion data from an ongoing international survey （調(diào)查） of 6 ，625 people in 55 countries．The survey asked participants to rate 12 colors on how closely they were associated with feelings including joy，pride，fear，and shame．
   The researchers paid particular attention to the data for yellow，and analyzed how different factors一including hours of sunshine，hours of daylight，and the amount of rainfall一lined up with the emotions people reported for the color．The two best predictors of how people felt about yellow were the annual amount of rainfall，and how far they lived from the equator （赤道）．
   Overall，people were more likely to associate yellow with joy when they lived in rainier countries that lay farther from the equator，researchers reported in the Journal of Environmental Psychology．In Egypt，the likelihood of yellow being associated with joy was just 5.7% ，whereas in chilly Finland it was 87.7%．In the United States，with its mild climate and amber waves of grain，people's yellow joy association levels were between 60% and 70%．
   The researchers also checked whether associations changed with the season - whether，for example，people in a certain country liked yellow more in the winter than they did in the summer．They found that opinions about color remained fairly constant year-round 一even when the weather changed，the data on yellow-joy associations were as good as gold．

2．In February，before the outbreak of Covid-19，I sold my old-style car.I thought it wouldn't be a big deal：I live in London within walking distance of three subway stations and countless bus stops.I own a bike；there are taxis and supermarket delivery services，and I joined a car-share program，all of which can save me a big sum of money to fund my future green transport.
   Then the lockdown（封鎖）happened and being car-free suddenly felt like a big deal.I couldn't get a supermarket delivery.I couldn't take my broken garden chairs to the recycling center.And a few days into lockdown，somebody stole my bike!
   When the lockdown stopped，it just got worse.I was eager to go to the countryside or beach，but taking public transport or a taxi felt like too much of a risk.The car-share program turned out to be unbelievably difficult to deal with—every area has its own rules about where you can and can't park，and taking a car-share vehicle beyond the city is impossible.And renting a car is clearly expensive and time-consuming.
   So last month I did a U-turn.I felt guilty but also a sense of satisfaction：I had tried，but the pandemic（疫情）beat me.Most of all，I got freedom，sitting behind the wheel （方向盤）and getting to wherever I want.Don't get me wrong.I still expect to travel without creating greenhouse gases and pollution.But life in a pandemic has drawn attention to some of the disadvantages of public transport，such as time and money wasted on the road to offices and the risk of Covid-19.It has also stressed our need to review our relationship with the environment.Problems with public transport have meant that the ownership and use of a car has become quite a useful thing.

3．When it comes to becoming eco-conscious，many people choose to start with something simple：recycling.But it's not as simple as everyone seems to believe.
   Indeed，the desire for some people to recycle can lead to ill-informed decisions about what can and cannot be recycled，and non-recyclable objects are accidentally put into the recycling bin.The practice is what is known as wish cycling.
   Wish cycling boils down to the idea that just about anything can be recycled，and that if you put it into a recycling bin，those who are responsible for it will find a way to recycle it.This is obviously not true，because，despite everything that you've been told by the media，not everything is recyclable.
   Small non-recyclable objects that are attached to recyclables are generally acceptable.For example，glue and tape attached to paper will be removed in the recycling process without any trouble.But improperly recycling broken eyeglasses，plastic shopping bags，food waste and greasy （油漬）pizza boxes could cause problems to the recycling process.
   The objects in the recycling bin are typically sorted by machines at recycling centers，not people.These complex machines are designed to separate plastics，paper，and other recyclables.If something is thrown into the bin that shouldn't be there，it could end up damaging the machine，which means the recycling center could lose time and money every time people decide to wish cycle.Sometimes，a non-recyclable object is able to sneak （溜）past these sorting machines.If this happens，the non-recyclable object ends up in a load of recyclables that will be sold for the recycling center to make a profit.
   However，having just one non-recyclable thing mixed in can pollute the entire load of recyclables，which has to be thrown away.
   So what you as a consumer need to do is make your own recycling practice most functional.The best way is to educate yourself.There are certain general rules when it comes to recycling that everyone should know.
