Question about particles
A few days ago I bought a book for preparing Nihongo Nouryoku Shiken N5 (actually I don’t intend to do the test yet, I just want to learn more from what my teacher has taught so far). However, there are some things that are different from what I've learned in class:
(1)------------------------------------
Sentence: The meeting is finished at 5
The book's version: かいぎは 5じで 終わります。 (using particle で)
What I've learned in class: かいぎは 5じに 終わります。 (using particle に)
(2)------------------------------------
Sentence: Next year Mr. Yamada returns to Japan
The book's version: 山田さんは 来年 日本に 帰ります。(using に; on the book: "に is used before words: 帰ります, 行きます, もどり ます")
What I've learned in class: 山田さんは 来年 日本へ 帰ります。 (using へ before 帰ります or 行きます)
(3)-------------------------------------
I saw these sentences on the book:
i. きのう 日本人の 友達へ てがみを だしました。
ii. 私は かぞくに てがみを かきました。
If those sentences are translated into English, particle へ in the first sentence and particle に in the second sentence, both have same meaning: “to”. What’s the difference?
Well, I'm still in the Shokyu 1 level (very very basic level) and I'd just joined the Japanese course 2 months ago. Maybe there are some things about my questions that aren't taught to me yet by my teacher, but I'm such a curious person and I really want to learn more than I’ve been taught. So, please help me! :)
Anyway, today I made an essay for my homework. When my teacher read it, she didn’t believe that the essay was done by myself because it didn’t look like a beginner-made (beside the fact that I’m in Shokyu 1 class, I’m the one among the students who never learned Japanese formally at school) and the other students didn't make the essay as complicated as I made. I didn’t like that situation, she looked like accusing me for cheating or something. She doesn’t know that I learn Japanese from many things, especially books (I love reading!). I didn’t believe that she did it. I was too shock that I didn’t defend myself :(
Okay whatever about past, just forgive her and I’ll prove my ability on the final exam. I’ll do my best to get perfect score. Wish me luck! :D
P.S.
I've learned something important from what I'd experienced today:
do not overdo in doing something. anything that's overdone will cause problem. proportional is the best way to do everything :)
