Ashita Lucy wa nani o shimasu ka.
=Lucy wa ashita nani o shimasu ka.

Kenta wa ashita doko e ikimasu ka.
=Ashita kenta wa doko e ikimasu ka.

These are all correct, I think. I don't see any difference in meaning (unless you're talking about 'informational structure' 'focus' or 'presupposition' etc.)

OK, I finally finished Lesson 4 and it's pretty easy talking about how to form a question including a transitive verb and an object and questions in past tense that have yesterday, questions in future tense that have "tomorrow".

Now, I am going to review all this...
Again I am discussing about that I would like to mention the subject in both questions and statements.
Here is the first one...

A: Did you eat ice cream yesterday?
I wrote this in Japanese using two ways:
1st by mentioning the subject (Pronoun you).
A: Anata wa kinou aisukuriimu o tabemashitaka.
あなたはきのうアイスクリームおたべましたか。

2nd one by not mentioning the pronoun.
A: Kinou aisukuriimu o tabemashitaka.
きのうアイスクリームおたべましたか。

So, can the two questions be correct?
Thanks.

A: Anata wa kinou aisukuriimu o tabemashitaka.
あなたはきのうアイスクリーム【を】たべましたか。

A: Kinou aisukuriimu o tabemashitaka.
きのうアイスクリーム【を】たべましたか。

Both are correct again....

Ok thanks a lot.
Now is there an easy way to memorize the days of the month...
It looks difficult...
1st day of the month, 2nd day, 3rd,.......31st
Is there a simple way to remember them?

Hmm...simple way...?

As to 「ついたち　ふつ-か　みっ-か　よっ-か　いつ-か　むい-か　なの-か　よう-か　ここの-か　とお-か」, I think you should just accept and memorise them.

When we count something we may say 「ひと-つ、ふた-つ、みっ-つ、よっ-つ、 いつ-つ、むっ-つ、なな-つ、やっ-つ、ここの-つ、とお」. If you already know this, it may be of some help, no?

And 20th is 「はつ-か」. If you know that '20 years old' is 「はたち」, it will be easier, no?

As to the other days (from 11 to 19 and from 21 to 31), just add 'にち（nichi）' after the numbers, ex. ２４ｔｈ＝「にじゅうよん-にち」.

(oh wait--we say 'nijuu-yon-nichi' but don't say 'nijuu-shi-nichi'. And 19th is 'juu-ku-nichi', not 'juu-kyuu-nichi... !!...why?)

OK, what about the months?
Is there a simple way for it??

I made a way for the last 3 months (October, November, and December) each of them begins with juu, except that we add ichi from January ichigatsu to November juuichigatsu
and add ni from February nigatsu to December juunigatsu

So, what about the other months? From March to September?

OK,
I made a song for months from March to September..
Listen to it and tell me if it's good, for me I think I will memorize them.
11.mp3

san shi goga roku shichi hachi kuga

Isn't it にじゅうよっか (nijyuuyokka)?

・・・あっ！！ほんまや！！　
I'm sorry~~...


Ah!! Yes! I think we say 'じゅうよっかjuuyokka' for 14th and 'にじゅうよっかnijuuyokka' for 24th.

17th may be either of 'じゅうななにちjuunananichi' or 'じゅうしちにちjuushichinichi', right? Wait, do we also say 'にじゅうなのかnijuunanoka'? Oh no~~now I'm confused!

And now, why don't we say 'にじゅういつか' for 25th or 'じゅうみっか' for 13th...??

Oh~thank you for your song...(^^)

Basically they are 'numbers(from 1-12)+ がつgatsu', like 'ichi, ni, san, she, go, roku, shichi, hachi, ku, juu etc.' + gatsu.

...Or would it be easier to put them like this...'each, knee, sun, she, go, rock, hitch, hatch, q, jew' + 'gatsu'...? Just kidding! (^^) Here's 'q' for 9, but we use 'ku' for the month.
