A

The French couple，Katia and Maurice Krafft，shared an attraction to volcanoes，one that perhaps approached an addiction.There are many people interested in volcanoes，but very few who are willing to climb an erupting crater(火山口) and approach the flowing lava(岩浆)．Katia and Maurice did a lot of work，shooting photographs and films of volcano eruptions，always being the first on the scene of an active volcano，and the ones who fearlessly came to just a few feet from lava flows.They were not only highly respected by volcanologists all around the world，but also envied.

The couple met in the 1960s when they were both students at the University of Strasbourg，and got married in 1970.Both of them were attracted to volcanoes since childhood.Upon graduating，Katia and Maurice pursued their careers as volcano observers with no financial support at all，just their own savings，which they spent on a trip to Stromboli to observe the eruption of the volcano.

They took an incredible and valuable set of photographs of the near-continuous eruption.People were curious about the photographs，while public officials working on threatening volcanoes found them useful.This interest in their work helped the French couple to establish a career in documenting eruptions.Now able to obtain financial support for their work，Katia and Maurice visited hundreds，if not thousands，of volcanoes around the globe.They traveled and recorded eruptions，always getting closer to the danger than anyone else.

In June 1991，along with 40 other people，the Kraffts set out to film the eruption at Mount Unzen in Japan.A sudden and unexpected flow took place and all the people in its path were killed.Later investigation revealed that Katia’s and Maurice’s bodies were closest to the volcano crater.They were 44 and 45 years old respectively.

In their 25-year-long career，the couple documented hundreds of volcanoes，and their work consists of thousands of still photos,300 hours of film materials，a number of books，and scientific articles published in BulletinofVolcanology.

The commonly held belief that it takes 21 days to form a new habit can be traced back to a 1960 book by plastic surgeon Maxwel Maltz called Psycho–Cybernetics.In his work treating patients who had gone through facial reconstruction surgery，Maltz noticed that it typically took around three weeks for them to adjust to seeing their new faces in the mirror.He also found that individuals who had lost a limb still sensed “phantom(幻觉的)”pains in the missing arm or leg for about 21 days.

Based on these perceptions(认知) of recovery time after significant physical changes，Maltz theorized in his book that it likely takes a minimum of 21 days for the neurological path ways in our brains associated with old behaviors and habits to go away，and for new mental images and routines to take firm root.This idea of a standardized 21-day formation period for habits soon became widely accepted.

However，Maltz was drawing causal inferences rather than conducting strict scientific research.It wasn’t until 2010 that health psychologist Phillippa Lally at University College London decided to properly study habit formation timelines.She designed a year-long experiment that tracked 96 participants as they each established a single new habit of their choosing.Every day，subjects reported on whether they successfully performed their intended behavior that day as well as how automatic the action felt.

Lally’s findings revealed that on average，it took 66 days before a habit became a normal part of a routine and felt automatic.But results varied widely，with habits forming anywhere from 18 days up to 254 days between individuals.Consistency(连贯性) was the key factor in successfully making a behavior habitual，with sometimes missing days not stopping overall progress.

This landmark study proved the assumed 21-day standard to be false and showed that a wide range of timelines are normal.

5．What is Maltz’s assumption based on?

A．A strict scientific research.B．Psychological work.

C．His personal observations.D．Carefully designed surveys.

6．Why did Lally’s team conduct the research?

A．To support Maltz’s theory on habit formation.

B．To explore the factors in affecting habit formation.

C．To identify the timelines for establishing new habits.

D．To explain advantages of developing good behaviors.

7．What do we know about Lally’s findings?

A．It is harder to form a new habit than to stick to an old one.

B．There are large individual differences in forming habits.

C．Most participants took 66 days to make a behavior habitual.

D．Occasional stops have a big effect on the process of habit formation.

8．What is the best title for the text?

A．Does It Really Take 21 Days to Build a New Habit?
