Question 20 is based on the passage you have just heard.

​​​​​​​听力原文

    Good morning. Today, (21) [I would like to talk to you about my charity ReBicycle.] But before that, let me introduce someone. This is Leila Rahimi. She was so scared when she first moved to New Zealand that she struggled to leave the house, and would spend days working up the courage to walk to the supermarket for basic supplies. After a few months of being quite down and unhappy, she was invited to join a local bike club. (19) [At this time, ReBicycle got involved and gave Leila a second-hand bicycle. Within weeks, her depression had begun to ease as she cycled.] The bicycle totally changed her life, giving her hope and a true feeling of freedom.

    (20) [To date, ReBicycle has donated more than 200 bikes to those in need, and is now expanding bike-riding lessons as demand soars.] With a bike, newcomers here can travel farther, but for almost no cost. The 3 hours a day they used to spend walking to and from English language lessons has been reduced to just 1 hour.  

    (21) [Our bike-riding lessons are so successful that we are urgently looking for more volunteers.] Learning to ride a bike is almost always more difficult for an adult, and this can take days and weeks rather than hours. So if any of you have some free time during the weekend, please come join us at ReBicycle and make a difference in someone’s life.  

20. What is ReBicycle doing to help those in need?

解析：A。录音中间部分说到，ReBicycle已经向有需要的人捐赠了200多辆自行车，由于需求激增，现在ReBicycle正在扩大自行车骑行课程的规模。A项内容全部复现，故正确答案为A。

错项排除：B项利用donations进行干扰，但录音中说的是ReBicycle已经捐赠（donated）了200多辆自行车，并不是让当地人捐款，故排除。录音中间提到了travel farther和no cost，但此处说的是有了自行车，新搬来的人出门时可以走得更远，录音中的no cost表示骑行几乎不需要成本，并非C项所说的免费（free）的公共交通；而travel表示“出行”，并非D项所说的为游客提供徒步旅行（walking tours）服务，故C、D两项错误。
