Grammar, Usage / 1. Biology had given me the fundamental yet interesting knowledge' - Grammar correction in sentences [5]

Dear Icturn87,

Actually I wanted to post my all essay, however it's my consideration just to keep 'em.

1. Thank you for your advise. It is true that I wanted to use past tense. I will attempt to re arrange the sentence according to your advise.

2. Actually, I was Biology student and there is genetics subject as a part of Biology (besides Microbiology, Biochemistry subject, etc). Genetics was my favourite one. So, is it fine to use "the study of genetics"? As I was not Genetics major but Biology. Pls advise.

3. Okay. Thank you for your advise.

4. Yes I do. However, that wishes was in my past. I meant to express my past wishes by using "wished" through work and discover the cause of many diseases. Pls kindly advise how I suppose to write in a proper way?

5. Yes I did. That wishes was in my past also. Pls advise.

6. Thank you for your advise.
7. Thank you for your advise.

8. No, they didn't. I, myself who did it. Actually, I have had experience as a Public Health workforce in the leaving area when I was in the college. Through this activity, I've got knowledge about it. So I expressed it like "It had introduced me about the importance of encouraging healthy behaviours to people". Is it correct?

9. Thank you for your advise.
10. Thank you for your advise.
11. Thank you for your advise.

12. Yes true, I wanted to express that way :) Thank you for your advise.

Dear Ransom2092,

Thank you so much for helping.

1. I use "had" because I want to state the past situation. Biology was my previous education. So, is it fine to use "had" instead of "has" ? Pls advise:)

However according to Icturn87, I should say "gave" to describe condition in the past. Biology gave me the fundamental knowledge about the complexity of biological system.

2. Thank you for your advise.
3. Thank you for your advise.

4. I wrote "wished" because I want to state situation in the past. My wish in the past-> wished??
So according to you, it become I wished to discover the cause of as many diseases as possible. Is it correct?

5. Thank you for your advise.
6. Thank you for your advise.
7. Thank you for your advise.
8. Thank you for your advise.
9-12. Thank you for your advise.

Writing Feedback / Learning about foreign countries by watching and travelling [3]

I definitely agree, although in few situations I could learn more about foreign phrases, sentences or words by only watching them regularly.
Besides the original language, thing that makes difference between just watching and visiting is the common people's habit in specific area, for an easy example like hugging as a "thank you" word, kissing beloved lips in unclosed room, etc.
