阅读理解     Wang Mengshu, an expert at the Chinese Academy of Engineering, said at a group discussion on the sidelines of the annual session of the National People's Congress that Wi-Fi should not be provided on high-speed trains, as it might disturb communication signals of trains and would also cost a lot in keeping trains in good condition. He also encouraged passengers to enjoy the views, instead of fixing their eyes on tiny screens of smart phones and laptops. However, on last Tuesday Beijing Youth Daily said it should be market demand that decides whether the Wi-Fi is offered on the trains or not.     An increasing number of residents, especially young white-collar workers, are addicted to their smart phones rather than face-to-face interactions, thanks to the extensive Wi-Fi coverage across the country. That partly justifies Wang's opposition to the offering of Wi-Fi on high-speed trains, because they are not supposed to be dependent on high-tech devices. It is also evident that passengers on trains without free Wi-Fi will use their smart phones and other mobile devices less. However, whether the trains should provide a free Wi-Fi service fundamentally depends on customer demand.     In other words, state-owned as it is, the China Railway Crop still has to obey relevant market rules, and provide technologically possible services to passengers if that is what they want. It cannot turn a blind eye to customers' wants "for the sake of their well-being".     Free Wi-Fi, in fact, is already available on a lot of buses and coaches. This is a natural response to their competition with trains (especially high-speed ones), which are significantly faster and safer. The bus companies have been forced to improve their services to survive. It requires proper guidance, not a total ban on the bus, to make up for the negative effects of high-end technologies, such as people's increasing addiction to smart phones. （1） Which is one of the reasons for Wang Mengshu saying no to free Wi-Fi on the train? A . Making communication signals of trains stable. B . Not focusing on the screens of phones and laptops. C . A high cost of keeping trains in good condition. D .

Wang's opposition proves reasonable in part. C . Most people think Wang's suggestion hard to carry out. D . Young white-collar workers consider Wang's advice right. （3） What does "market rules" in the 3rd paragraph refer to? A . Demand depends on supply. B . The market decides purchasing power. C . Everything depends on money. D . The market is in the control of customers. （4） According to the last paragraph, the author agree       . A . People should drop smart phones. B . Every coin has two sides. C . High-end technologies cause more side effects. D . A total ban on free Wi-Fi is reasonable. 答案： C B D B
