Hi, Minju! A handwritten letter is such a heartfelt present for someone. It's so sweet of you to give it. 

Anyway, thank you for the wonderful questions again. Let us discuss more in the class. See you!

Yes! I have ever given letter which I wrote directly.
>> Yes. I have given a letter which I wrote directly. 

1. “It's about 1 degrees.” or “It's about 1 degree.”
Which sentence is correct between the two sentence?

>> It's about 1 degree. 
2. It was two and a half hours.
Should I put ‘a’ in front of ‘half’?

>> Yes, you need 'a' before half. (instead of saying, two and one-half hours, one=a)
It was two hours and 30 minutes.
Can I write it like this?

>> Yes, this is also correct. 

Also >> It's 150 minutes. 
3. What does ‘smoothe’ mean?

>> Smoothe is a verb that means to make something smooth. For example: My skirt is wrinkled so I used an iron to smoothe it. 
4. He gave me a cake
I can't use pronouns in the place of ‘a cake’, right?

>> If a subject/object is not human, we use the pronoun "it". (example: He game me a cake so I ate it. It = cake)
5. ‘soft th’ is pronounced by biting the tongue slightly with my teeth, right?

>> Try pronouncing the N sound, but with your tongue touching the bottom of your front teeth, and then relax your tongue from that position (allowing air to pass)
