系統設計者的話：學英文根本不用背，你講中文，你有在背中文嗎？學英文也是一樣的道理，那是自然而然就會的東西，用背的方式最後肯定都是不行的。 更多...

最好的學習就是有英文的父母，不斷的跟你說話、耐心的教導你，時間長了，你也就慢慢就融入其中了。

但是我們沒有英文父母怎麼辦？看影片學英文就學的起來嗎？學不起來。

我們從小到大，也看過了不少英文電影，至少也看過1、200部也跑不掉，但是為什麼看了這麼多的英文電影，英文還是很爛呢？

主要的原因是我們沒有從基礎性的強化學習。舉個例子，西方的幼兒出生時，他至少聽了各種大人講英文至少聽了2年，才慢慢開始說英文、與大人互動。

而且都是一字一句慢慢的說、慢慢的教、漸進式的、慢慢的、越來越習慣、越來越聽的懂、越來越會說的過程。

那麼我們看的影片、電影過程中，都是大人成熟型的講話速度、方式、語調，我們怎麼可能跟的上？

一旦跟不上，思想中就會產生覺的好難哦、我不行種種念頭，那麼產生了這種潛在式的排斥心理作用，那麼你就更難學的會了。


所以我們必須打好基礎、深厚的基礎，萬丈高樓平地起，唯有打下深厚的基礎，後面你走的路才會越來越順。

程式界裏有句話，程式債欠的越多，最後就只能放棄。學英文也是一樣，英文單字債欠的越多，你就直接上來文法、句型、語調，最後也只能放棄。

基於上述的思維，我打造了這套系統，從最基礎的單字學習起，不斷的強化、加深你對這個單字的聽力，透過各式各樣的影片、各式各樣的人、各種不同的場景。

就只是為了訓練一個單字的聽力，無數的人跟你講同一個單字，講個20遍、50篇、100遍(且不重覆)，我就不信學不起來。


這套系統做出來後，我自己在使用的過程中，確實真的能聽出來他們講的這個單字，而且他們講的速度再快也能聽的出來。

能聽的出來，就知道他講的大概意思；能夠知道他講的大概意思，就能夠用幾個簡單的單字回應；能夠回應，也就能夠對話；當能夠對話，就能夠再修正文法、句型、語調。


我的目地就是希望自己至少能聽的懂人家在說什麼，用英文跟人家對話，大家共同努力、學習。若有其它想法或對這套系統設計的建議，也可以與我聯絡：ichich2013@gmail.com

PETER
o'shaugnessy
Hi
wesley
hales
It
really
depends
on
the
goals
the
above-the-fold
content
in
the
first
15k
right
hard
to
do
a
responsive
like
uber-optimized
site
at
an
achievable
cost
effort
patrick
hammond
700k
on
the
mobile
site
So
it's
a
work-in-progress
as
to
whether
the
responsive
STEVE
luke
ft
you're
in
the
same
business
publishing
A
lot
of
these
things--
STEVE
it's
an
organizational
constraint
not
responsive
that's--
luke
blaney
Yeah
there's
a
lot
of
that
performant
in
one
browser
and
make
for
example
you
can
optimize
to
chrome
they
got
new
audiences
no
there's
still
some
arguments
for
and
against
I
think
it's
just
fundamentally
harder
If
you
look
at
the
top
the
responsive
or
not
responsive
websites
on
the
mdot
sites
on
the
top
5000
sites
it's
almost
the
responsive
websites
it's
just
that
mdot
naturally
lends
doing
a
responsive
one
too
So
you
sort
of---
GUY
it's
true
and
correlation
is
not
causation
and
all
that
launched
websites
it's
hard
to
cache
it
if
you're
offline
and
not
about
things
like
wearables
and
non-conventional
devices
that's
called
a
seamless
segue
people
So
do
concatenation
and
spriting
become
anti-patterns
so
i'll
defer
to
you
andy
davies
I
think
what
we're
aware
of
is
what
we're
So
we're
merging
say
javascript
together
can
cache
them
individually
When
do
they
become
anti-patterns
spriting
already
is
an
anti-pattern
need
one
icon
it's
just
that's
just
wesley
hales
Well
we're
kind
of
doing
it
now
It
runs
speedy
inaudible
web
but
I
don't
really
you've
got
a
lot
of
controllers
or
modules
browsers
that
don't
support
it
that's
going
to
save
your
older--
But
it
doesn't
matter
on
the
newer
browsers
In
that
if
you've
got
a
web
font
that's
referenced
in
css
Then
we
start
parsing
the
css
and
parsing
the
dom
of
concatenating
or
in-lining
stuff
in
css
it's
the
granularity
you
get
by
not
having
you'll
add
all
sorts
of
javascript
and
you
don't
start
concatenating
On
the
browser
side
the
browsers
won't
parse
and
evaluate
the
javascript
until
it's
complete
Then
we
can
the
client-side
code
PAT
meenan
Right
they
get
sprites
still
and
using
the
old
anti-pattern's
where
gzip
inaudible
caching
form
the
best
it
can
STEVE
So
effectively
you're
saying
wesley
hales
I
think
you're
not
going
for
concatenating
versus
not
concatenating
on
the
http/2
andy
davies
Well
you
get
penalized
in
cache
terms
wesley
hales
But
spdy
pushes
straight
to
the
cache
I
mean
it
pushes
straight--
andy
davies
automate
it
Do
you
have
server-side
logic
that
detects
and
spits
out
the
html
because
fundamentally
it
Differently
for
spdy
or
http/2
versus
http
1
now
we've
got
70%
of
our
traffic
coming
in
that's
spdy
or
http/2-capable
but
it
doesn't
break
wesley
hales
Right
like
modpagespeed
that's
protocol-aware
So
it
will
do
the
optimizations
for
http
1
and
it
will
do
different
optimizations
for
http/2
you've
got
to
get
all
of
the
web
server--
PAT
meenan
effectively
spdy's
out
there
right
PAT
meenan
ie
11
chrome
firefox
it's
effectively
what's
your
server-side
support
and
what's
your--
STEVE
So
if
you're
expecting

patrick

patrick
hammond
Hi
So
inaudible
as
I
said
in
a
inaudible
last
year
above-the-fold
conten
is
in
the
browser
PAT
meenan
Yeah
I
mean
it's
fundamentally
So
put
on
load
handlers
for
your
above-the-fold
images
Doing
it
generically
that's
when
and
trying
to
automatically
tell
them
that's
a
much
harder
currently
unsolved
problem
not
user-visible
The
single-page
apps
that
scroll
down
forever
there
is
start
rendering
the
rum
from
ie
and
chrome
windowperformancems
first
pane
is
ie's
PAT
meenan
Right
basing
any
decisions
based
on
that
Who
realistically
in
their
websites
who's
actually
doing
custom
instrumentation
the
pageonload
event
as
the
kindof
de
facto
that's
without
distracting
the
user
they
dealt
with
inaudible
page
isn't
ready
that
pageonload
but
it's
actually
usable
patrick
hammond
Just
that's
great
that's
good
to
hear
patrick
hammond
On
that
note
something
we're
starting
to
have
discussions
about
inaudible
UNKNOWN
AUDIENCE
1
inaudible
interested
inaudible
realistically
mobile
gives
you
that
direct
path
to
purchase
there's
ad
dollars
behind
it
you've
STEVE
A
bit
like
bitcoining
you've
The
next
question
is
from
patrick
hammond
patrick
hammond
it's
me
again
So
how
we're
now
very
well-equipped
to
measure
But
yet
we're
seeing
a
rise
in
large-scale
long-living
single-page
applications
and
new
metrics
and
new
visualizations
to
measure
long-living
applications
that
we're
in
single-page
apps
PAT
meenan
Well
I
mean
you've
got--
hopefully
the
browsers
are
giving
you
especially
in
the
single-page
apps
If
you're
not
getting
the
primitives
you
need
wesley
hales
I
think
it
becomes
more
of
a
rendering
thing
too
got
a
single-page
app
that
doing
lots
of
ajax
requests
of
that
round-trip
time
for
that
back-end
ajax
request
together
for
those
single-page
apps
luke
blaney
I
think
it
also
depends--
app
whether
you're
doing
these
click-and-wait
for
the
content
luke
blaney
Local
storage
and
websql
or
sp
depending
on
the
right
inaudible
how
do
you--
wesley
hales
So
it
comes
down
to
rendering
at
that
point
we
need
new
tools
new
metrics
and
new
visualizations
you're
saying
if
a
single-page
app
measuring
but
requestanimationframe
is
probably
your
best
friend
I
mean
figuring
out
if
your
single-page
is
behaving
it's
doable
but
it's
complicated
a
manual
tester
using
it
and
going
that's
a
bit
sluggish
there's
some
things
that--
inaudible
but
having
somebody--
luke
blaney
Yeah
but
that's
what
that's
inaudible
UNKNOWN
SPEAKER
there's
a
combination--
luke
blaney
It
depends
on
the
browser
wesley
hales
There
is
no
fold
in
the
browser
and
then
you've
got
your
sub-stories
So
you
basically
want
to
prioritize
inaudible
PAT
meenan
Yeah
so
that's
not
ie-specific
implementations
for
images
while
still
letting
the
browser
tooling-wise
so
there's
a
couple
of
rum
tools
but
inaudible
the
frameworks
and
I
It
comes
down
to
framework
instrumentation
would
build
this
instrumentation
right
into
those
frameworks
I
thinl
with
the
framework
providers
instrumentation
inaudible
to
the
point
of
frameworks
on
the
one
hand
frameworks
to
instrument
the
browser
at
runtime
while
it
disseminates
through
the
browser
inaudible
and
re-processing
it
to
the
browser
Plus
there's
also
the
point
you're
making
about
the
browser
vendors
Rich
howard
will
automated
front-end
optimization
tools
STEVE
So
feo
tools
like
mod_pagespeed
or
riverbed
Stingray
aptimizer
you're
a
fan
of
varnish
that's
a
reverse
proxy
type
inaudible
luke
blaney
I
think
I
would
classify
varnish
because
varnish
behaves
like
an
http
proxy
it'll
follow
by
default
it'll
follow
http
headers
be
entry-level
to
mid-level
with
appliances
it's
made
me
unsecure
actually
If
I
can
sling
$50000
at
riverbed
Give
andy
inaudible
a
comment
inaudible
andy
davies
we're
trying
to
optimize
because
I
think
it's
crashed
let's
go
So
that's
going
to
be
http/2
versus
http
11
we're
already
struggling
with
just
going
to
be
new
devices
wearable
technologies
tvs
wesley
hales
And
for
those
of
us
PAT
meenan
And
I
think
there's
some
class
of
optimizations
is
image
transcoding
and
supporting
webp
like
oh
that
bit
of
javascript
do
you
see
the
world--
we've
talked
about
components
we've
talked
about
http/20
the
next-generation
cdns--
But
you're
tuning
it
and
you're
configuring
it
to
your
needs
if
you
have
a
way
to
do
it
automatically
it's
great
to
inaudible
yourself
You
were
discussing
stuff
like
batching
is
bad
PAT
meenan
So
batching
a
gpu
doesn't
the
gpu
doesn't
deal
with
the
sprite
can
take
it
offline
because
we've
paul
lewis
My
question
got
tweeked
And
I
hashtagged
perfmatters
on
that
STEVE
hashtag
perfmatters
always
good
wesley
hales
Right
it's
the
same
argument
or
do
you
want
a
better-looking
site
there
are
optimization
options
In
the--
take
out
the
glyphs
we're
not
using
Which
takes--
Open
sans
off
Google
it's
pointless
about
fonts
and
stuff
like
that
OK
we
are
expecting--
it's
going
