题目

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。 Tourism has its benefits, but there are disadvantages as well. While it stimulates(刺激) the local economy and creates jobs, many cities see destruction to landmarks and disruption of citizens' daily lives. If you've ever visited a large city or famous site, there's no doubt you've seen the marks left behind by tourists. 16. The attractions vary from the Luxor Temple in Egypt to the Colosseum in Rome and the ancient Buddhist grottoes in China. Whether it's a visitor's initials, a date or a phrase, the message is one of disrespect. . The litter left behind by visitors can be astonishing. Every year people who visit Mount Qomolangma leave behind a trail of plastic bottles and other trash. In the US, people flock to New Orleans for Mardi Gras celebrations, and in their wake, so much garbage is left behind that it takes the city weeks to recover. Even if tourists act responsibly, the number of visitors alone presents a risk. 18. Reefs attractions can be permanently damaged. Other negative effects of tourism may not be as evident. Tourists may visit a popular destination with little or no regard for those who call it home. 19. Visitors who don't respect local traditions and culture only lessen the value of the experience, not to mention cast future tourists in a negative light. Tourism most definitely has its advantages, of course, economic and otherwise. There is nothing greater than experiencing a new place, people or culture firsthand. . A. Tourism can cause damage to local environment and culture as well. B. People have defaced (损坏外观) historical sites around the world. C. Some tourists even kill the local wildlife to eat, which badly damage the balance of the natural environment. D. Sometimes they may act rudely to residents or simply not observing community rules. E. Ancient structures suffer increased wear and tear due to large crowds. F. In addition to graffiti (涂鸦), tourism can cause environmental damage. G. But to protect this privilege, we must show that we are respectful and appreciative rather than destructive. 答案：【1】B【2】F【3】E【4】D【5】G
