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引導，表示了一種對比關系。“年輕人迫不及待地要沖向這個巨大的移動游樂場，而該嘉年華場所附近的居民卻在為可能造成的環境損害擔心。”B是原文再現。
30. Where was the World Carnival held last year?
[C]解析：短文說：“去年夏天，環球嘉年華給北京的國際雕塑公園的草地留下了一個巨大的疤痕。”可見去年的環球嘉年華是在國際雕塑公園舉辦的。C正確。表示地點名稱的專有名詞選項，清楚地表明了本題的問題。“聽到什么標記什么”，根據問題“選擇什么”，是這種題的妥當解決辦法。
31. What are the visitors advised to do at the World Carnival?
[B]解析：文章結尾介紹了參加環球嘉年華活動的注意事項，其中一項說：“在享受驚險游樂設施時要先取下眼鏡。”B正確。細節題，根據關鍵詞聽取原文信息，判斷選項正誤，最后據問題作答。原文有兩個Do not wear的內容，正好排除A、C；原文還說Do not eat too much，D也不對。只有B與原文一致。
