Snow

was

a

famous

doctor

in

London.There

wasthe

most

deadly

disease

called

“King

Cholera”

of

its

day.Every

time

there

was

a(n)outbreak,many

people

died.John

Snow

wanted

to

face

the

challenge,find

thecauseand

solve

this

problem.At

that

time.there

were

two

theories

about

cholera.The

first

suggested

that

cholera

multiplied

in

the

air.The

second

suggested

that

people

absorbedthis

disease

into

their

bodies

with

their

meals.John

Snowsuspected

the

second

theory

was

correct

but

he

neededevidence.So

he

collected

data

to

test

the

two

theories.Hemarked

on

a

map

where

all

the

dead

people

had

lived

andthe

map

gave

a

valuableclue.It

seemed

the

water

was

to

blame.Next,John

Snow

looked

into

the

source

of

the

water

for

these

streets.He

found

two

other

deaths

in

anotherpartof London

linked

to

the

Broad

Street

outbreak.With

enoughevidence,he

announced

with

certainty

that

polluted

watercarried

the

disease

of

cholera.36By

following

the

seven

stages

we

cansolve

problems

in37补充阅读People

do

not

analyze

every

problem

they

meet.

Sometimes

they

try

to

remembera

solution

from

the

last

time

they

had

a

similar

problem.

They

often

accept

theopinions

or

ideas

of

other

people.

Other

times

they

begin

to

act

without

thinking;they

try

to

find

a

solution

by

trial

and

error.

However,

when

all

these

methods

fail,the

person

with

a

problem

has

to

start

analyzing.

There

are

six

stages

in

analyzinga

problem.First

the

person

must

recognize

that

there

is

a

problem.

For

example,

Sam’s

bicycleis

broken,

and

he

cannot

ride

it

to

class

as

he

usually

does.

Sam

must

see

that

theris

a

problem

with

his

bicycle.Next

the

thinker

must

define

the

problem.

Before

Sam

can

repair

his

bicycle.

hemust

find

the

reason

why

it

does

not

work.

For

instance,

he

must

determine

if

theproblem

is

with

the

gears,

the

brakes,

or

the

frame.

He

must

make

his

problem

morspecific.Now

the

person

must

look

for

information

that

will

make

the

problem

clearer

andlead

to

possible

solutions.

For

instance.

suppose

Sam

decided

that

his

bike

doesnot

work

because

there

is

something

wrong

with

the

gear

wheels.

At

this

time.

hecan

look

in

his

bicycle

repair

book

and

read

about

gears.

He

can

talk

to

his

friendsat

the

bike

shop.

He

can

look

at

his

gears

carefully.38After

studying

the

problem,

the

person

should

have

several

suggestionsfora

possible

solution.

Take

Sam

as

an

illustration.

His

suggestions

mightbe:put

oil

on

the

gear

wheels;

buy

new

gear

wheels

and

replace

the

old

ones;tighten

or

loosen

the

gear

wheels.Eventually

one

suggestion

seems

to

be

the

solution

to

the

problem.Sometimesthe

final

idea

comes

very

suddenly

because

the

thinker

suddenly

sees

somethingnew

or

sees
