5．Travis is the manager of G&G where he is responsible for forty employees （雇员）and profits （利润）of over $2 million per year．He's never late to work．He does not get upset on the job．When one of his employees started crying after a customer screamed at her，Travis took her away．"Your working uniform is your shelter，"he told her．"Nothing anyone says will ever hurt you．You will always be as strong as you want to be．"
Travis picked up that lecture in one of his G&G training courses，an education program that began on his first day and continues throughout an employee's occupation．The training has，Travis says，changed his life．G&G has taught him how to live，how to focus，how to get to work on time，and how to master his emotions （情绪）．Most importantly，it taught him willpower．
At the center of that education is an extreme focus on an all-important habit； willpower．Dozens of cases show that willpower is the single most important habit for a person's success．
And the best way to strengthen willpower is to make it into a habit．"Sometimes it looks like people with great self-control aren't working hard-but that's because they've made it automatic，"Angela Duckworth，one of the University of Pennsylvania
researchers said．"Their willpower occurs without them having to think about it．"
The company spent millions of dollars developing programs of study to train
employees on self-control．Managers wrote workbooks that serve as guides to how to make willpower a habit in workers'lives．Those courses arc，in part，why G&G has grown from a sleepy company into a large one with more than seventeen thousand stores and profits of more than 10 billion a year．

A．learn to give lectures
B．attend education programs
C．design a working uniform
D．develop a common hobby
34．Willpower will become a habit when employees canD．

A．G&G has grown into a large company．

2．Science can't explain the power of pets，but many studies have shown that the company of pets can help lower blood pressure （血压） and raise chances of recovering from a heart attack，reduce loneliness and spread all-round good cheer．
Any owner will tall you how much joy a pet brings．For some，an animal provides more comfort than a husband/wife．A 2002study by Karen Allen of the State University of New York measured stress （紧张） levels and blood pressure in people-half of them pet owners-while they performed 5minutes of mental arithmetic （算术） or held a hand in ice water．Subjects completed the tasks alone，with a husband/wife，a close friend or with a pet．People with pets did it best．Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates．With pets in the room，people also made fewer math mistakes than when doing in front of other companions．It seems people feel more relaxed （放松）around pets，says Allen，who thinks it may be because pets don't judge．
A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits．Researchers at Northwestern Memorial Hospital spent a year studying 36fat people and their equally fat dogs on diet-and-exercise programs； a separate group of 56people without pets were put on a diet program．On average，people lost about I1pounds，or 5% of their body weight．Their dogs did even better，losing an average of 12pounds，more than 15% of their body weight．Dog owners didn't lose any more weight than those without dogs but，say researchers，got more exercise overall-mostly with their dogs-and found it worth doing．
