第41. 至44. 題為題組 The proverb “When in Rome, do as the Romans do” may be familiar to you, but the new rules may not. Rome introduced a host of new laws in 2019 to protect and preserve the heritage of the city. Visitors and residents can now get into trouble if they violate the new regulations by doing idiotic behaviors like jumping into the city's famous Trevi Fountain or messy eating on the steps of historical monuments. Among these new rules, there's one that has got people talking: no sitting on the Spanish Steps. Made famous by the movie Roman Holiday, these steps draw large crowds of people every day. Tourists can still take photos, but anyone caught sitting down can face a fine of up to €400. Strange as it may seem, the law was made with intentions to keep the ancient city of Rome beautiful for generations to come. The new rules do not target only at the tourists, though. Some actors in tourism industry also need to be careful. One new rule forbids anyone to dress up as Roman centurions around tourist spots and charge tourists for photos. Another rule bans advertising or selling "skip the line” tickets around popular tourist attractions like the Colosseum. Local residents cannot hang laundry outside on wires across the streets and there must be no singing or playing musical instruments on public transportation. When in Rome, do as the new rules order you to do so you can protect the delicate monuments. 41. What is the main purpose of this passage? (A) To warn people against tourist traps in Rome. c(B) To protest against the implementation of new laws. (C) To introduce some of the new rules in Rome and the reasons. (D) To present the beautiful monuments and tourist sites in Rome. 42. Which of the following is FALSE? (A) People can still take selfies on the world famous Spanish Steps. (B) New rules were introduced to prevent the ancient city from being damaged by tourists. UC) Vendors cannot sell “skip the line” tickets to the Colosseum around it because of the new laws. (D) Actors cannot put on the costumes of Roman centurions around tourist sites. heritage for
