Passage Two
The World Carnival is set to start its second funfair in Beijing at the end of the month. [29]While young people can hardly wait to rush to the huge mobile amusement park, people living in the neighborhood where the carnival locates are worrying about the possible environmental damage. [30]Last summer the World Carnival left Beijing with a huge scar on the grassland of the International Sculpture Park. To help the settlement of the mobile amusement park, about 55,000 square meters of greenery was removed last year, including nearly 200 big trees. This year however, the World Carnival has been more careful in settling people's concerns. An environmental evaluation has been done to the whole project and the report approved. William Stevens, Chairman of World Carnival Ltd. further explains. And if you're keen to go to this year's carnival and you've never been to one before, the following are some tips our entertainment editors have summarized.
Do not wear skirts or clothes made of filmy material;
Do not hang down your hair loosely;
[31]Take off your spectacles before enjoying thrill rides;
Do not wear slippers;
Leave games for the end of your day's enjoyment to avoid the burden of carrying around big prizes;
Do not eat too much or leave your stomach empty before enjoying yourself;
And finally, do not overindulge in the games or rides.

答案解析：
Questions 29 to 31 are based on the passage you have just heard.
29. What do people living in the neighborhood worry about?
[B]解析：短文第2句由while引导，表示了一种对比关系。“年轻人迫不及待地要冲向这个巨大的移动游乐场，而该嘉年华场所附近的居民却在为可能造成的环境损害担心。”B是原文再现。
30. Where was the World Carnival held last year?
[C]解析：短文说：“去年夏天，环球嘉年华给北京的国际雕塑公园的草地留下了一个巨大的疤痕。”可见去年的环球嘉年华是在国际雕塑公园举办的。C正确。表示地点名称的专有名词选项，清楚地表明了本题的问题。“听到什么标记什么”，根据问题“选择什么”，是这种题的妥当解决办法。
31. What are the visitors advised to do at the World Carnival?
[B]解析：文章结尾介绍了参加环球嘉年华活动的注意事项，其中一项说：“在享受惊险游乐设施时要先取下眼镜。”B正确。细节题，根据关键词听取原文信息，判断选项正误，最后据问题作答。原文有两个Do not wear的内容，正好排除A、C；原文还说Do not eat too much，D也不对。只有B与原文一致。
