Parents around the world often urge children over and over-wash your hands!It can be difficult，however，to get children to remember to wash.But what if washing hands was connected to a fun creative activity？What if instead of simply reaching for the soap，a machine could drop it right into your hands？
Well，such a machine was recently built by a boy and his sister in the U.S.jye.ai of Maryland as part of a creative competition.The not-for-profit Rube Goldberg Organization is holding the competition.
Every year，the Rube Goldberg competition assigns a specific task，considering inventions that use complex systems to carry out a simple everyday task.At first，the task for 2020 was supposed to be "turn on a light." But when the COVID-19 happened，the task was changed to "drop a bar of soap into someone's hand."
Those taking part in the competition are schoolchildren.But with schools closed to slow the spread of the virus，organizers changed the rules.This year，the team can include any family members and people were asked to send in recordings of the machines to compete.One thing has not changed：The machine must complete the task in less than 10 steps.
In Maryland，the Diel family wanted to enter.So，Caitlin and her brother Ben designed and built their own Rube Goldberg machine.Next，they had to demonstrate that it could complete the task-throwing the soap just right to be caught in someone's hand.After 106 failed attempts，they finally had success.With their video demonstration，they can now enter the competition.
Dr Anne Glowinski teaches child psychiatry（精神病學(xué)）at Washington University School of Medicine in St.Louis.She said that "creativity and play" connects with children.It is better than the message. "We have to wash our hands because of this horrible virus".Glowinski added.

2．Each year on Halloween，children look forward to trick-or-treating （不請客就搗亂） for candies．But for some kids，eating Halloween candies can be dangerous．
That's because one out of every 13 kids in the Us have a food allergy（過敏癥）．They are allergic to ingredients（成分）in many Halloween candies，such as peanuts，tree nuts，milk，eggs，and beans．If they eat these foods，they will get sick or even die．
"I had to throw away all my candies with tears，" eight-year-old Conlen said．Conlen is allergic to peanuts，tree nuts，and dairy．Twelve-year-old Kylie is allergic to peanuts and tree nuts．She has been trick-or-treating only twice． "I brought my candies home and gave them to the neighbors，" Kylie said． "It felt terrible．"
But this year，Conlen，Kylie and other kids with food allergies will have a chance for a happy Halloween．That's because nearly 100，000 households across the US have promised to take part in the Teal Pumpkin Project（TPP），which was started last year by Food Allergy Research & Education（FARE）．FARE is an organization that works to improve the lives of people with food allergies．Through the project，the households agree to have nonfood items for trick-or-treaters，including trinkets（小飾品） and toys．
To take part in the project，people buy a teal（藍(lán)綠色） pumpkin or paint a pumpkin teal and place it in front of their house．The painted pumpkins let trick-or-treaters know that nonfood items are available there．The households also add their home addresses to an online map，making it easier for trick-or-treaters to find them．
Kylie loves the idea．"The TPP makes Halloween fun and safe，" she said．"It makes me feel like a normal kid，and it makes everyone feel included．"
（1）To Conlen and Kylie，the past Halloween were．
A．upsetting and dangerous

3．Besides the excitement of travel，one reason to study abroad is that you will experience new customs，holidays，foods，art，music，and politics first-hand.
"I learned the language and am now fluent，but perhaps what's more important is how much I learned about cultures，people，and myself.I learned this from the viewpoint of an active member of the community and my host family，not from the tourist's point of view，" says Andrew，who studied in Poitiers，F(xiàn)rance.
Another reason for studying abroad is that you'll gain self-confidence.Christina studied in Caracas，Venezuela，a city of more than 3 million people and a huge change from her hometown of 35，000!Christina says she learned how to better stand up for herself and her beliefs and to express herself in another language.What could make you more confident than that？
Living away from home can also help you adjust in the transition（過渡）to college and adulthood.Mathew says he returned from studying in Australia with confidence and a real interest in international affairs that made him different from his peers（同齡人）. "After having gone abroad in high school，I found the transition to college a breeze—moving 560 miles from home didn't seem particularly frightening after having lived thousands of miles away."
Most of all，it's fun while you're studying in a different learning environment.
（1）What is the passage mainly about？
A．Learning a language.
B．The excitement of travel.
C．Living in a foreign country.
D．The benefits of studying abroad.
（2）What did Andrew pay special attention to while studying abroad？
A．Host families.
B．The foreign cultures.
C．Places of interest.
D．Community problems.
（3）According to the example of Christina，what do we know about studying abroad？
A．It can change our habits.
B．It can offer us opportunities.
C．It can increase our knowledge.
D．It can build our confidence.
（4）What do the underlined words "a breeze" in paragraph 4 probably refer to？
A．Something very important.
B．Something very interesting.
C．Something very easy.
