5 . When the pandemic(流行病) hit last spring, 9-year-old Zoe Benard of California started baking(烘) sweet treats with family members. But what started out as a fun way to pass the time has become a one-girl mission to raise $10,000 for Parkinson’s disease research.

Through a series of weekend bake sales since July, the homeschooled fourth-grader has taken in nearly $3,500 through the sale of her homemade banana bread, cookies and brownies. For a weekend sale, she’ll bake up to 25 pieces, four to five pans of brownies and three batches(炉)of cookies.

One hundred percent of the money made by selling treats is given to Team Fox, a research organization set up by actor Michael J.Fox, who has the disease. Zoe’s grandfather, 75-year-old Joe Contogenis, who is the inspiration for her sales, also has Parkinson’s. Contogenis can no longer run or play tennis the way he did before his diagnosis(诊断) three years ago.But he comes to every one of Zoe’s bake sales and is often moved to tears by the generosity of Zoe’s customers.

“She is a little entrepreneur(企业家) and has always been an out-of-the-box thinker,” Christine Eris, her mom, said. “we were cleaning our house out and found a magic set, and now she’s reading books on magic. She taught herself how to solve the Rubik’s Cube in a minute and a half. She just learns and practices things until she perfects them.”

Zoe sells her treats for $1 to $2, or $12 for a full piece of banana bread. Eris said many customers give more because they know it’s for a good cause. One customer arrived with a $200 check and another with a $100 bill. Zoe said her goal is to keep hosting sales until she reaches her $10,000 goal. Then she will either start over or find another cause to support. She also plans to start her own children’s cooking channel on YouTube because she finds the process of baking so fun.

6 . Many people, including some successful men, wear the same clothing daily to focus their decision-making energy on more important things.     1     Julia, an art teacher, is wearing the same dress for the first 100 days of school to create awareness of the environmental costs of fast fashion.

Available online or from various shops, it allows everyone to adopt the latest fashion trends instantly. Though that sounds like a win-win for all, the rapid change in styles and the affordable prices result in impulse (冲动) purchases, many of which are thrown away after being worn just once or twice.    2    

Julia's idea for the “One Outfit (服装), 100 Days” began as a comment she made to her husband during the summer.     3     Moreover, it would serve as a great lesson for her new students. Selecting a perfect outfit for the challenge was a little tricky.After some consideration, Julia settled on a plain dress. Though she has a backup dress, Julia plans to use it only if absolutely necessary.

    4     It has also inspired some of her colleagues and her husband to take up the challenge. Julia says the experiment has forced her to rethink her attitude towards clothes. She values things more now—respecting the planet for her children and trying to value herself in a different way, as opposed to caring so much about what she looks like.     5     Reuse, recycle, and, most importantly, reduce.

A．Julia is also tired of making decisions on small things.

B．The experiment has aroused curiosity of many students.

C．Julia's “One Outfit, 100 Days” challenge, however, has a selfless aim.

D．Thanks to Julia's idea, the whole school began to follow her challenge.

E．She hopes more people will learn from her and apply the 3Rs to their life.

F．Over 21 billion pounds of cloth ends up being waste yearly in the US alone.

G．Thinking further, she decided it would be a way to show her eco-friendly lifestyle.
