Please I need help. English isn't my first language.

Fill in the blank space with the right words.

1. The teacher invited David and to his office.
(Myself , me , I , himself )

2. are good friends .
( I and he , he and I , I and you , he and me)

3. Jane and Jesse love ___ very much.
(themself , each other, one another) .

4. Mary : Who is there ?
Emma : It is ___ (me, I , myself , you)

5. One has to address ___ strictly to the task ahead
( himself , herself , oneself , themselves).
​

1.I
2.he and I
3.each other
4.this is I
5.oneself

These are tricky even for people who know English.
For number one David and I is the proper way to say it
Number two is once again the proper way to say it but people don’t always say it like that
Number three is each other and is probably the hardest of all of these because they pretty much mean the same thing as one another
Number four is I even though most people would say it is me the proper way to say it is it is I
Number five would be oneself most would think it’s themselves but the proper way to say it is one self

Hope it helps have a great day
