Human creativeness is boundless. With the advance of science and technology, a complete new means of communication -- Mobile Phone came to the world, which, being not fixed in one place like ordinary phones, greatly facilitates telephone communication. Although using mobile phone is convenient, it also has some negative factors. It tells us that we should pay more attention to the mobile phone etiquette. There is a research on American mobile phone etiquette. People are using cell phones in a Manhattan subway. Most Americans believe that there are unspoken rules about using mobile phone etiquette, according to an online poll. It’s impolite to shout down their cell phones which may frighten other passengers. Checking emails, sending text messages and making telephone calls while in the company of other passengers are definite breeches of mobile phone manners. Texting during a date is also strictly forbidden. But the majority of American people questioned in the online poll said that they would not be offended if they received an electronic "thank you", instead of a written note and seventy-five percent had no objections to anyone using laptops, net books or cell phones in the bathroom. "Etiquette is first and foremost a question of awareness," said the author and etiquette expert Anna Post. But she described the results of the Harris Interactive poll commissioned by Intel as "pretty surprising statistics". Sixty-two percent of the 2,625 adults who took part in the survey agreed that cell phones, laptops, net books and other electronic devices are part of daily life. Fifty-five percent also thought that the demands of business mean people must stay connected, even if it involves taking a laptop on a holiday or answering a cell phone during a meal. Despite the need to be constantly connected and the general acceptance of the technology, people were more sensitive about technology abuses during holiday and religious activities. Nearly ninety percent of Americans think that cell phone use is unacceptable during a religious service and thirty percent admitted they would be offended if they received an online gift wish. But more than half revealed that they intended to send an electronic greeting card, instead of a traditional one. "These are issues about common sense," said Dr Genevieve Bell, an ethnographer and director of Intel’s User Experience Group, adding that the social rules of when and how it is appropriate to use the technology are still being formed.Which of the following sentences is fight according to the passage A. 75 percent of people in the online poll had no objections to anyone using laptops, net books and cell phones in the bathroom.B.
