[浙江北斗星盟2024高二联考]Waking up at the crack of dawn and going for a run might feel intimidating when you start trying to make it a habit. Weaving a significant new activity such as this into your regular routine obviously takes determination and time—but how much time is really needed to make that habit stick?
One popular idea suggests that it takes 21 days to solidify a habit. The “three-week theory” originated from the 1960 self-help book *Psycho-Cybernetics*, in which plastic surgeon Maxwell Maltz observed that it took his patients about 21 days to get used to their new appearance after surgery. Even without much solid research, the 21-day myth became widely accepted. It likely persists because it seems like such a reasonable amount of time, Colin Camerer, a behavioural economist at the California Institute of Technology who has conducted research on habit formation, explains.
Almost a half century later, researchers finally gathered strong evidence that countered this idea. A significant 2009 study on habit creation found that habits developed in the range of 18 to 254 days; participants reported taking an average of about 66 days to reliably incorporate one of the three new daily activities—eating a piece of fruit with lunch, drinking a bottle of water with lunch or running for 15 minutes before dinner. Consistent daily repetition is the biggest factor influencing whether a behaviour will become part of an automatic daily routine, says Lally, who is the first author of the study.
The type of activity is also a factor. A study conducted by Camerer and his colleagues showed that creating a handwashing habit took a few weeks, compared with the half year it took to develop an exercise habit. Handwashing, the study noted, is less complex than exercising and offers more opportunities to practise. The researchers also suggested that habit formation depends on the effort that a person puts into practising an activity and on the presence of environmental cues that will remind them to carry out the behaviour.

答案： A
[语篇导读]本文是一篇说明文。一项研究推翻了人们所认同的21天养成新习惯的理论，表明一个习惯平均需要约66天才能成为日常生活的一部分，每日不断的重复、活动类型以及个人的努力都会影响习惯的养成。
1.D 推理判断题。根据第一段内容可知，开头提到早起跑步，然后提出设问：需要多少时间来养成这个习惯呢？下文则介绍了人们普遍熟知的21天习惯养成理论以及推翻这一理论的新研究。由此可推知，本段提到早起跑步是为了引入本文话题：养成一个新习惯需要多长时间。故选D项。
2.C 细节理解题。根据第二段中的“Even without much solid research, the 21-day myth became widely accepted. It likely persists because it seems like such a reasonable amount of time”可知，人们认为三周是一个能够坚持下来的合理时间，所以普遍能够接受这一时间跨度，因此即使没有可靠的理论依据，“三周理论”也被人们一致认可。故选C项。
3.A 细节理解题。根据第三段中的“Consistent daily repetition is the biggest factor influencing whether a behaviour will become part of an automatic daily routine, says Lally, who is the first author of the study.”可知，重复是养成习惯的关键因素。
关键点：题干中的stick与文中的become part of an automatic daily routine为同义替换；文中的Consistent daily repetition与A项Repeated practice为同义替换。本题解题的关键在于识别题干、原文、选项中的同义表达并进行对照。
4.B 主旨大意题。根据全文内容，尤其是第一段中的“but how much time is really needed to make that habit stick”可知，文章主要介绍一项研究推翻了人们所认同的21天养成新习惯的理论，表明一个习惯平均需要约66天才能成为日常生活的一部分，故文章主要介绍了需要多久才能养成习惯这一问题。故选B项。
