Some Japanese queries.?

Question

1) ano gakkou ha rippa de hoterunoyou desu.

I just wanna know the function of de here. thanks.

2) Yamadasan ha ryokou ni iku youna kakkou wo shite imasu.

What's kakkou o shite? Is kakkou 格好？

3) Kodomo demo yomeru you ni, muzukashii kanji ha tsukawanaide, tegami wo kaite kudasai.

What's the function of demo here? Please give me the trans of this sentence for better understanding of demo. Thanks.

4) How did you get from kiku to kikoeru? Shouldn't it be kikeru?

5) futoranai you ni, amai mono ha tabenai you ni shite imasu.

What's the meaning of the second you ni? What's its function?

6) kakko ni, [tame] ka [you] wo kakinasai.

Why is it just one ka? By right should it be "kakko ni, tame ka you ka wo kakinasai." or sth along that line? What I learnt was, for eg "anata ha amaimono ga hoshii desu ka, karaimono ga hoshii desu ka?"

7) kuruma demo, koko kara eki made 30 pun dewa ikemasen.

Does it mean "Even if you travel by car, you can't get there in 30 minutes"?

8) Going/Planning to do sth in Japanese is eg "ikou/tabeyou to omoimasu"

When it is in the third person we must use "to omotte iru" with "sou desu" or "rashii desu" or "no desu".

Why must it be "to omotte iru" not "to omou"?

What is the function of "no desu" here? Is it like "sou" and "rashii"?

Thanks!!

Answer 1

1)

"rippa de" is conjugated form of "rippa da"

The form continues the sentence like "rippa da soshite".

2)

>What's kakkou o shite? Is kakkou 格好？<

Yes. It is 格好, appearnce or costume

3) Kodomo demo yomeru you ni, muzukashii kanji ha tsukawanaide, tegami wo kaite kudasai.

In this case, "demo" means "even"

"Please write your letter without difficult kanji so that even children can read."

or

"Please use kanji easy enough for children to read."  

4)

"kiku" is for "listen (to)"

"kikoeru" is for "(can) hear"

5)

"you ni" expresses one's intension or purpose.  

6)

You are correct.

the word or phrase with particle "ka" at the end of it is always lined up with another.

But "ka" is also used as a conjunction, like "or".

The "ka" in the example you ask is that kind of "ka"

7)

Does it mean "Even if you travel by car, you can't get there in 30 minutes"?

Yes.

"It takes more than 30 minutes from here to the station even by car."

8)

First,

I'm sorry I have no grammatically correct answer.

This is my personal answer.

"omou" is a subjective expression.

We don't know or understand what he or she thinks(omou) accurately on time.

So by using "omotte iru", the distance between his or her heart and others' may be expressed  

Second,

"no desu" indicates pressumption with firmer convictions than "sou" and "rashii".

I hope I could help you.
