is everyone ready let's begin hello
everyone nice to see you again today's
idiom is by the book by the book alright
and this by is not to purchase not by
Bui but BY buy by the book alright so
let's imagine there's a book okay and
this book has all the different
situations or things in the world and if
you don't know what to do
you look in the book yeah it tells you
what to do it tells you the best thing
for that situation so you can look in
the book and you can know exactly what
to do yeah by the book
look at the book by the book alright so
let's listen to some examples and try to
understand this idiom
why do you think the bread didn't rise
when we baked it I'm not sure we did it
by the book oh okay so they made some
bread but it didn't rise it didn't rise
and they don't know why because they did
it by the book they did it exactly like
the recipe set they did it perfectly but
it didn't rise they don't know why okay
let's listen to the second example
do you think we are lost we can't be
lost we came according to the book
alright so the first person thinks they
are lost
and the second person said no no we
can't be lost
we came here according to the book by
the book yeah we maybe looked at the map
or we follow the directions so we're not
lost
okay so by the book means to do exactly
what you should do
okay so to follow the directions
perfectly or to follow the recipe or to
do exactly what you're supposed to do
all right
by the book if for example hmm I made a
cake but the cake didn't come out right
and I looked at my recipe and I did it
perfectly I cooked it by the book but
it's wrong and my friend says oh you
forgot to change Celsius from Fahrenheit
oh okay so that was the problem I did it
by the book I'd put the right recipe
right ingredients but I forgot to change
the temperature for Japan mmm
so by the book means to do it exactly
right yeah I'm driving perfectly yeah I
follow all the rules I Drive by the book
okay so I wonder how about you in your
life do you do everything by the book or
do you do some things in your own way
you decide to do it differently not by
the book all right so you can talk about
how you do things by the book or not by
the book and I'll see you next time
