15．Smokingmultiplies（成倍增加）the risk of heart attacks and other health problems．

14．Lately，everywhere you look，people are running around with fitness trackers on their wrists．Along with a smartphone and an accompanying app，these trackers can report how many calories you've burned and the distance you've traveled．Still curious about yourself？You can also learn the number of stairs you've climbed and steps you've taken，metrics（度量）it had never occurred to me to wonder about．
Not one to resist peer pressure，however，I paid $100for a Fitbit Flex．I chose that brand on  the basis of research：asking my friend Sari which tracker she used．
The Fitbit website offered instructions on setting up my new tracker．I entered my height  and gender（性别）and certain information I considered none of its business：birth date and  weight．Then I established goals．The American Heart Association recommends that we all walk 10，000steps a day-about five miles，and so does Fitbit．I decided 6，000steps was a good place for me to start．
I changed my tune when，on day one，I hit 6，000steps and tiny LED lights flashed on my wristband．Confident enough now，I went back to my phone and upped my goal to 8，000steps．
OK．So I got a little obsessed（着迷）．On day five at a department store，I decided to check my progress．My target number was just 275steps away!I walked around the dress department watching my smartphone register each step I took．I hate to tell you how much pleasure this gave me．
Now I always wear my tracker，not because I've grown to love fitness but because I like being trendy and self-absorbed．Last night I was leaving a restaurant when Fitbit emailed to congratulate me on walking more than 10，000steps．Who wouldn't love a tool that turns your every footstep into an accomplishment？

13．"Business is war．"The traditional language of business certainly makes it sound that way：winning the competition，getting market share，beating up suppliers，locking up customers．There are the victors and the losers．
But today in doing business，you have to listen to shareholders，work with suppliers，keep good relations-even with competitors．That doesn't sound like war．Besides，there are few victors when business is looked upon as war．
Most businesses succeed only if others also succeed．Business is competition and cooperation as well．In other words，business is war and peace．
To bring together competition and cooperation，we turn to game theory．Game theory provides that whether one person wins or loses depends on what other people do．It is particularly effective when there are many interdependent factors and no decision can be made in isolation from other decisions．
Game theory breaks down the game into key elements：players，added values，rules，tactics（计谋），and scope （PARTS）．Every element affects the result of the game．This means that each of the five elements gives you a way to change an existing game into an entirely new one．Change one of the PARTS，and you change the whole．
Why change the game？An old Chinese saying explains：If you continue on the course you're heading，that's where you'll end up．Sometimes that's good，sometimes not．You can play the game very well，and still suffer great loss． That's because you're playing the wrong game：you need to change it．Even a good game can be made into a better one．Real success comes from actively shaping the game you play-from making the game you want，not taking the game you find．

8．Six years ago，a Miami woman walking through the hall of an office building casually noticed two men standing together．Several minutes after her leaving，the men murdered a person working in the building．Police investigators determined that the woman was the only witness who had seen the two suspects，and could possibly describe them．In an interview with police，her memory of the men proved disappointingly unclear．
Several days later，psychologist Ronald P．Fisher was brought in to get a more complete description from the woman．Fisher's interview produced a breakthrough （突破）-the woman reported a clear picture of one of the suspects．She then recalled several details about his appearances．This information gave police important leads that enabled them to arrest the      suspects and close the case．
Police investigators found the help from Fisher because of his rich knowledge in conducting the so-called cognitive （认知的） interview，a kind of memory-rebuilding process．In its original form，the cognitive interview focuses on guiding witnesses through four general recalling techniques：thinking about physical surroundings and personal feelings that existed at the time of past events，reporting everything that comes to mind about those events no matter how broken or unconnected，retelling events in kinds of time orders，beginning to end，end to beginning，forward or backward，and accepting different views while recalling events．
Usually，an interviewer begins the cognitive approach by encouraging the witness to take an active role in recalling information rather than giving answers only to someone else's questions．The witness first describes what happened in his or her own words，with no interviewer interruptions．The interviewer then goes further with specific techniques，such as having the witness tell the details of what happened from different aspects．
Experiments with police detectives trained in this demanding interview method find that they get nearly 50% more information from witnesses than before training，while error rates remain about the same．

A．To give an description of a murder case in an office．

C．disappointing
D．interrupting
65．What is the key point of the cognitive interview？B
A．The interviewer should interrupt the witness from time to time．
B．The witness is encouraged to take an active role in recalling information．
C．The interview should take place outside the police station．
D．The witness should recall details at the scene of the event．
