hello everyone you're back with me at
anglo-link
this is the second video of our series
to help you master the English verb
tenses in the first video I talked about
the differences between present simple I
do and present continuous I'm doing I
hope you watch that video if you haven't
I recommend you go and watch that one
first because today we're going to talk
about the differences between I am doing
present continuous and I have been doing
that's present perfect continuous so
when you're ready let's get started
right then let's look at the differences
between present continuous
I'm doing and present perfect continuous
I have been doing
starting with formulation first present
continuous as you remember from the
previous video we need the verb to be
in the present tense and the main verb
plus ing I am playing tennis
you are playing tennis he she is playing
tennis you we they are playing tennis
let's look at present perfect continuous
as the name indicates now you need the
verb to be in the present perfect tense
I have been playing tennis you have been
playing tennis he she has been playing
tennis we you and they have been playing
tennis quick recap present continuous
the verb to be
in the present tense plus the main verb
with ing present perfect continues the
verb to be in the present perfect tense
plus the main verb with ing now that's
easy let's move on to usage when do we
use the present continuous and when do
we use the present perfect continuous
you remember from the first video that
the present continuous is for an action
in progress
remember the examples I'm talking to you
now you are listening to me at the
moment it's raining present perfect
continuous refers to an action that
started in the past and is still in
progress so if I tell you how long I've
been talking to you I need to use the
present perfect continuous I've been
talking to you for five minutes
we can use the word since to show when
the action actually started I've been
talking to you since 11:30 so you're
listening to me now right if we say how
long you've been listening to me we
switch to the present perfect continuous
you've been listening to me for a few
minutes last example it's raining now it
started this morning it has been raining
all morning it started when I woke up it
has been raining since I woke up right
let's look at some timelines to make it
even clearer for you
look at present continuous here is the
timeline this is now and the action is
happening now and will go on for a
little while longer
let's look at present perfect continuous
on a timeline the action started in the
past and has continued until now and
will go on a while longer if you say
exactly when it started
you use the word since if you say how
long it's been going on
you use the word for right I hope that
that's really clarified the difference
between present continuous and present
perfect continuous for you the most
common mistake is to use the present
continuous instead of the present
perfect continuous you're likely to say
or - here I'm working here for two years
I'm working here only refers to now if
you say how long you need to change it
to present perfect continuous I have
been working here for two years
let's look at another example you may
often say or here I study English for
six months and now you know you can't
say this because you're saying how long
you need to use the present perfect
continuous I have been studying English
for six months let's look at the next
example you may here we are waiting
since two o'clock what should we say
correct
we have been waiting since two o'clock
and the final example what the common
mistake is saying something like he is
doing his homework since he woke up he
is doing his homework now but he has
been doing his homework since he woke up
excellent
