In the 1950s, a plastic surgeon(整形外科医生)by the name of Maxwell Maltz began to notice that many of his patients took about 21 days【小题1】they got used to seeing their new face after an【小题2】(operate)—like a nose of job, for example.

【小题3】 (promote) by the observation of this unusual pattern, Maltz looked inward, into his own life, and noticed that it also took about 21 days【小题4】(adjust) to a new house someone just moved into. These experiences【小题5】(eventual) led Maltz to publish his famous 1960s book Psycho-cybernetics, in【小题6】he states that “it requires a minimum of about 21 days for an old mental image to disappear and a new one to form.” The book sold more than 30 million copies and is still【小题7】print today. This “21 days” figure【小题8】(repeat) countless times ever since. It has been republished and adapted in thousands of self-help books and TV shows. There’s a problem though. The “21 days” time window for cementing(巩固) changes in habit is【小题9】(little) a statistical fact and more like a myth. Maltz never performed a careful and thorough study using the【小题10】(science) method. His statistics are not accurate. But that doesn’t mean that there aren’t scientists who have made a genuine inquiry.
