Question 1 is based on the news report you have just heard.

 听力原文：

    (1) A 9-year-old girl in New Mexico has raised more than $500 for her little brother who needs heart surgery in Houston Texas this July. Addison Witulski's grandmother Kim Allred said Addison probably overheard a conversation between family members talking about the funds needed to get her little brother to treatment.

    "I guess she overheard her grandfather and me talking about how we’re worried about how we’re going to get to Houston, for my grandson’s heart surgery,” said Allred. She decided to go outside and have a lemonade stand and make some drawings and pictures and sell them.

    (2) That’s when Addison and her friends Erika and Emily Borden decided to sell lemonade for 50 cents a cup and sell pictures for 25 cents each.

    Before Allred knew it, New Mexico State Police Officers were among the many, stopping by, helping them reach a total of $568. The family turned to social media expressing their gratitude saying, “From the bottom of our hearts, we would like to deeply thank each and every person that stopped by!”
