I’ve been looking at the difference in sentences that express future events: those using “BE going to ɪɴꜰɪɴɪᴛɪᴠᴇ” versus those using “BE ᴠᴇʀʙ-ing” (sometimes called the present continuous or present progressive).
If I understand correctly, the difference is:
The BE going to ɪɴꜰɪɴɪᴛɪᴠᴇ form is used for future plans (or events) that are certain:
I am going to study physics.
The BE ᴠᴇʀʙ‑ing (present continuous) form is used for future appointments or arrangements:
I am meeting Jane on Tuesday.
One of the comparison examples I found in a video is the following:
|№||Future using “BE going to ɪɴꜰɪɴɪᴛɪᴠᴇ”||Future using “BE ᴠᴇʀʙ‑ing”|
|1||I am going to show her around the town.||I am showing her around the town this afternoon.|
|2||She is going to study Psychology.||She is studying Psychology at college next year.|
|3||He is going to see his lawyer next week.||He is meeting his lawyer on Tuesday.|
|4||They are going to meet again soon.||They are meeting at 1 o’clock tomorrow.|
My problem with that table is in the third example:
He is going to see his lawyer next week.
Why did the presenter use the BE going to ɪɴꜰɪɴɪᴛɪᴠᴇ future in example ⑶ instead of the BE ᴠᴇʀʙ‑ing future?
Isn’t this a meeting at a specific date (next week)?
If that sentence is correct, then why does She is studying Psychology at college next year. use the BE ᴠᴇʀʙ‑ing present continuous form? How does next week differ from next year?
Another quick question
I assume that in They are going to meet again soon, it is expressing the future using BE going to ɪɴꜰɪɴɪᴛɪᴠᴇ future because soon is not a specific date to license the BE ᴠᴇʀʙ‑ing way of expressing it.
Am I correct?
