【閱讀理解】Passage Two Thailand is to ban smoking on some of the country’s most popular tourist beaches, with the prospect of up to a year in prison for those caught lighting up, according to reports by local media. The move follows a recent survey of litter on Patong beach, Phuket – visited by millions of foreign tourists each year – which found an average of 0.76 cigarette butts per square metre in a sample area, which would amount to 101,058 butts on the 2.5km-long stretch of sand. The survey was undertaken by the country’s department of marine and coastal resources, which described it as a “serious problem”. Discarded cigarette butts accounted for a third of rubbish collected by the department. “Cigarettes have a direct effect on the natural environment,” director general Jatuporn Buruspat told the Phuket Gazette. “The butts clog the drains contributing to floods. When the cigarettes stay under the beach sand for a long time, it also negatively affects the eco system. And then when the chemicals from the cigarette butts reach the water, it also releases cadmium, lead, arsenic and some acid from insecticide which are poison to the natural food chain.” The ban, which will come into play in November, will affect 20 beaches including Patong, Koh Khai Nok, Koh Khai Nai (Phuket) and so on. After a trial period, the ban is expected to be enforced on all Thai beaches, as well as on passenger and tourist boats, to tackle the problem of butts damaging the underwater environment. Anyone found to be breaking the law will face one year in jail or a maximum 100,000 baht fine, or both. The Bangkok Post also reported the news, adding that Thailand has the sixth most rubbish-strewn areas of sea in the world.

【閱讀理解】Passage One Using a mobile phone while cycling is to be banned in the Netherlands amid mounting safety fears in a country where bikes outnumber people. A draft law scheduled to take effect next July will extend an existing 2002 ban on car and lorry drivers using their mobile phones at the wheel unless in hands-free mode to “ the use of a mobile electronic device while driving any vehicle (including a bicycle)”. The Dutch transport minister, Cora van Nieuwenhuizen, said the law was needed because the advent of social media and unlimited mobile data had changed how people used smart phones and the time they spent on them. Cyclists were excluded from the initial ban because of their lower speeds, Van Niewenhuizen said. “But in fact, using a phone is just as dangerous on a bike as it is in a car,” she said. “The fact is that whenever you’re on the road you should be paying full attention and not doing anything at all on a phone.” The increasing popularity of electric bikes meant cyclists’ average speed had risen, the minister added, while the country’s 22,000 miles of cycle lanes and paths had become more crowded. The Netherlands has more bikes – about 22.5m – than people: 17 million. Almost a quarter of the population cycles every day and cycle use has increased by about 12% since 2005; the average Dutch cyclist now covers more than 600 miles a year in 250-300 trips. Pedestrians, too, are at risk when they use mobile phones near cyclists: the Dutch town of Bodegraven last year launched a trial of foot-level traffic lights to prevent people wandering on to roads or cycle lanes while glued to their screens. While research suggests the number of cyclists who need emergency care after an accident involving a mobile phone may not be particularly high, less serious accidents have become increasingly common, particularly among young people. One in five bike accidents involving people aged 12 to 25 last year involved a smart phone, according to one estimate. A total of 206 cyclists died in traffic accidents in 2017, according to the central statistics office CBS, 17 more than the previous year. Opinion polling suggests 75% of the Dutch believe the “active use” of a mobile – calling, texting, playing games, downloading music, posting on social media or using other apps – on bikes should be outlawed, with a majority saying they had witnessed “dangerous situations” involving cyclists and smart phones.
