Writeacher, I really hope you can have a look at my last examples. I need to know which are wrong.

I still have a few doubts on the use of to/at/in after have been. Thank you for helping me.

1) I haven't gone out for a walk.
I have already been to school (or at school) today.
2) I haven't been to the cinema yet today.
3) I've already gone shopping online.
I've already done online shopping.
I've had this scooter for three months. (Not: I have gotten this scooter)
4) Katie, who likes rock music, has listened to it since she was twelve.

My sentences on "sport". I hope this time are correct!

1) He likes playing different sports.
2) He practises different sports.
3) Do you play/practise any sports?
4) I have already played on my Play Station 1.

All are fine ... in both groups of sentences. =)

You should definitely praise the positive points of every group. Home is a dwelling place and used to be a permanent or momentary shelter of a family, individual or a bunch of families.

Here is full thread of @kmalmarugan's assessment of where Modi/Shah went wrong in TN....and why this could be one of the nails (if not the only nail) in the Sanghi …

Here's an analysis of your sentences and whether they are correct or not:

1) I haven't gone out for a walk.
This sentence is grammatically correct.

2) I have already been to school (or at school) today.
Both "been to school" and "at school" are correct in this context. They convey the same meaning.

3) I haven't been to the cinema yet today.
This sentence is grammatically correct.

4) I've already gone shopping online.
This sentence is grammatically correct.

5) I've already done online shopping.
This sentence is grammatically correct.

6) I've had this scooter for three months. (Not: I have gotten this scooter)
This sentence is grammatically correct. However, it's worth noting that "I have gotten this scooter" is also grammatically correct, but it might not be the best choice in this context. "I have had this scooter" suggests ownership or possession over a period of time, which seems to be what you want to convey.

7) Katie, who likes rock music, has listened to it since she was twelve.
This sentence is grammatically correct.

Regarding your sentences on "sport":

1) He likes playing different sports.
This sentence is grammatically correct.

2) He practises different sports.
This sentence is grammatically correct.

3) Do you play/practise any sports?
Both "play" and "practise" are correct in this context. They convey the same meaning.

4) I have already played on my Play Station 1.
This sentence is grammatically correct.

Overall, your sentences are correct. Good job!
