7．Do's And Don'ts Of Donating
Giving up your unused or unwanted stuff is a great way to make space in your home for the items that you do enjoy on a regular basis．（36）D   Here are 4 do's and don'ts of donating your belongings．
    Do Prep Your Clothes
You've thoroughly cleaned out your closets and drawers，and have a mountain of clothing waiting to be donated．Before you bag up these pieces，examine each one to ensure that they're in good condition．Make sure all buttons are fastened，and that you can't see any dirty spots．（37）G
Don't Donate Damaged Items
The number one rule of donating your stuff is to make sure that it's in good，useable condition．Don't donate clothes or furniture with rips（裂口）or stains，chipped dishes，or books that are missing pages．（38）A   Find a local company that will recycle these items instead．
Do Donate More Than Just Clothes
（39）F  Stuffed animals，framed pictures，unused candles，small power tools，sports equipment，ornaments，baskets，blenders，dishes，glassware，utensils，silverware，pots and pans，curtains，blankets，toasters，mixers，pillows，towels，bed sheets，bikes，and exercise equipment are pretty popular donations．
（40）C
With a little common sense it's easy to figure out items that are ideal for donation．But unfortunately some people will throw away the contents of their home without a second thought．As a gentle reminder，it's never a good idea to donate car parts，flammable products，construction materials，weapons，or explosives．

You are self-centered．Many people do this unconsciously．You think you are the only one that matters，and often don't care what others have to say．If this is you，it's time to change．（37）
G
You are always in competition．Are you the person who has to be better than everyone else？If so，you're unattractive．（38）AIf they overcame their fear of heights and climbed 10 feet in the air，don't say，"That's all？I've climbed 30 feet!"Instead say，"That?s awesome．I'm really proud of you．"
（39）EYou are definitely unattractive when constantly asking why others don't see you as important as you think they should．For instance，your two friends went somewhere without you．It doesn't matter to them，but to you it does．Get over it．Your friends?lives don?t stop when you're not around．

Food waste，which has become a global issue，serves as a mirror that reflects various cultural and social issues in different countries．In the West，for instance，consumerism，the belief that it's a good thing to use a lot of goods and services，is often to blame for food waste．（18）G．Chinese people are well known for being hospitable and generous．Many even feel that they lose face if their guests have eaten all the food．On campus，a generation of single children is less aware of the food waste issue．Students nowadays are well protected by their families and hardly have any concept of how much toil（辛劳）others go through in order to provide them with the food they eat．（19）FThere are over 925 million hungry people in the world，most of whom live in underdeveloped countries and areas．They don't have enough food to eat．Many children die for lack of nutrition each year in some African countries．And farmers work very hard to grow the crops．（20）D．It's also important that everyone should think about how they can do their bit to reduce food waste．

19．Professor Barry Wellman of the University of Toronto in Canada has invented a term to describe the way many North Americans interact （互动） these days．The term is"networked individualism"．This concept is not easy to understand because the words seem to have opposite meanings．How can we be individuals （个体） and be networked at the same time？You need other people for networks．
Here is what Professor Wellman means．Before the invention of the Internet and e-mail，our social networks included live interactions with relatives，neighbors，and friends．Some of the interaction was by phone，but it was still voice to voice，person to person，in real time．
A recent research study by the Pew Internet and American Life Project showed that for a lot of people，electronic interaction through the computer has replaced this person-to-person interaction．However，a lot of people interviewed for the Pew study say that's a good thing．Why？
In the past，many people were worried that the Internet isolated （孤立） us and caused us to spend too much time in the imaginary world of the computer．But the Pew study discovered that the opposite is true．The Internet connects us with more real people than expected-helpful people who can give advice on careers，medical problems，raising children，and choosing a school or college．About 60million Americans told Pew that the Internet plays an important role in helping them make major life decisions．
Thanks to the computer，we are able to be alone and together with other people-at the same time!

17．Vitamin B could help reduce the effects of the most dangerous type of air pollution，according to a new study published Monday．A team of international researchers looked at the damage caused by PM2.5，which has the most severe impact on health．
The team found that something as simple as taking vitamin B daily could greatly reduce the impact of the tiny particles（颗粒） on the human body，although they stressed that research was in its early stages and the sample（样本） size was small．Once the particles are breathed in they can result in lung and systemic disease and stress，experts say．According to the WHO，92% of the world's population lives in places where the PM2.5 level is above the recommended level．However，how exactly these particles make people unwell is not fully understood．
For this study，published in the science journal PNAS，10 volunteers were initially exposed to clean air and given a placebo（安慰剂） to check their responses．The group then took another placebo for four weeks before being exposed to heavily polluted air from downtown Toronto，where thousands of cars pass every hour．The bad air was given to the volunteers through an"oxygen type"face mask．The experiment was then repeated，with each volunteer taking vitamin B daily--made up of 2.5mg of folic acid，50mg of vitamin B6，and 1mg of vitamin B12．B6 can be found in liver，chicken and nuts； and B12 in fish，meat，eggs，milk and some cereals．The researchers found that four weeks of B vitamin supplements reduced the damage of PM2.5 exposure by 28-76%．The results highlight how prevention at an individual level could be used to fight the harmful effects of PM2.5，the researchers said．
Future studies，especially in heavily polluted areas，are urgently needed to prove our findings and finally develop preventive methods using B vitamins to contain the health effects of air pollution，said one researcher．

28．According to this passage，how does PM2.5 do harm to our health？A
A．The particles can cause stress and lung disease as well．
B．The particles can lead to lung disease and heart attack．
