Hello, my very cute student. ^^ Thank you for sending  your homework. ^^ Please do check your corrections. I think that you must have forgotten about our discussion about using apostrophe -s  ('s). See you later. We will talk about it again, later. ^^

1.
Chanjong:I like Holiday's.

*Don't forget that we use 's for possession but for plural, we don't put 's.

2.

* Don't forget to put a subject. Be careful with your spellings.

3.
