“嫦娥一号”在完成了科学探测以后，在距地球三十八万千米的绕月轨道上向地面传回最后一段语音：“经过一年的太空遨游，我的任务已经结束……”关于这段语音传回地球的说法中正确的是(　　)

    Girls who lack confidence in school have a new champion. She is only 10 years old. Alice Tapper, a fifth - grader says, that her goal is to encourage girls of all ages to “be more confident in raising their hands”. Alice cared so much about the issue (问题) that she helped create a Girl Scout badge (徽章).

    The pink badge—Alice chose her favorite color—shows three hands reaching for the sky. It says, “Be brave. Raise your hand.”

    Alice's idea came during a fourth - grade field trip to Jamestown, Virginia. She found that boys raised their hands to answer questions even though they weren't sure of the answers. The girls just listened quietly.

    “Girls are afraid to raise their hands because they get shy. They have to be 90 percent sure, while boys just raise their hands and say, 'I know it,'” Alice said during a recent interview. She added that girls should have confidence, step up, and become leaders by raising their hands for women are equal to men.

    Alice's “Raise Your Hand” badge has become wildly popular, and not just in the United States. “People in Japan and China want to use the badge,” she said. “We sold out the badge quickly, but we're making more.”

    Alice wants to be a teacher when she grows up. But first, she wants to see a revolution in confidence for girls of all ages. She knows that won't happen overnight. “ It takes time,” Alice said, “but I can speed up the process.”
