The study, published in The Lancet, called for texts to be included in services to help people kick the habit. Other scientists said a text service could be offered globally. According to government statistics two-thirds of UK smokers say they want to stop. This study looked at 5,800 of them. Supportive texts were sent to 2,915 of the smokers for six months. The rest received only messages thanking them for taking part. They were sent five texts a day for the first five weeks and then three a week for the next 26 weeks. Participants could also text back for specific advice when they had strong desire or had begun to smoke again. Saliva tests for cotinine,which is made when nicotine is broken down by the body,were taken to determine if people had really given up. After six months,10.7% of those receiving texts had quitdouble the proportion among those doing it on their own. Dr Caroline Free, who led the txt2stop trial at the London School of Hygiene and Tropical Medicine,said: Text messages are a very convenient way for smokers to receive support to quit. People described txt2stop as being like having a friend encouraging them or an angel on their shoulder.” It helped people resist the temptation to smoke. The World Health Organization says nearly sixmillion die each year because of smoking, mostly in low-and middle-income countries. “The lessons learned from the txt2stop trial could not only provide a new approach to stop in high-income and middle-income countries, but could also provide a useful starting point for implementing behavioural change in resource-poor settings. It has also been suggested similar text messages could be used to help people modify other behaviour.1.What can be the best title of the passage?A.Text Messages Help Smokers QuitB.How to Quit Smoking EffectivelyC.Smoking Is Very Harmful to HealthD.The Function of Text Messages2.How did the researchers judge if a participant had really given up?A.By sending text messages to the participant.B.By making saliva tests for cotinine.C.By observing the participant for five weeks.D.By making a questionnaire.3.The underlined “It” in the passage refers to _.A.a friendB.txt2stopC.an angelD.quitting smoking4.In which part of a website may the passage appear?A.Entertainment.B.Advertisement.C.Education.D.Health.2、 The Internet has led to a huge increase in credit card(信用卡) fraud.
