Translation Help?!

[vramkissoon]

So I've just finished Lesson 9 of the Genki Textbook and I'm working on translating some sentences. I've done a few, but I'm not sure whether I've translated them correctly. Does anyone mind looking over them to see if they make sense? どうもありがとう！
I think Tadashi's father was good-looking when he was younger- わかいの時、ただしさんのお父さんはかっこういなかっ たと思います。
I think the concert began at 9 o'clock- 九時にコンサートをはじまらなかったと思います。
I don't think Mie received a letter from Mari- まいさんはまりさんからてがみをもらわなかったと思 います。(I'm really confused about this one)

First of all, what do you think about this?

I think Tadashi's father was good-looking when he was younger.(affirmative)
わかいの時、ただしさんのお父さんはかっこういなかったと思います。(negative)

I think the concert began at 9 o'clock.(affirmative)
九時にコンサートをはじまらなかったと思います。(negative)

I don't think Mie received a letter from Mari.(negative)
まいさんはまりさんからてがみをもらわなかったと思います。(negative)

Second of all, -i adjectives modify nouns directly, so it's わかいとき, not わかいのとき.

ごめんなさい！I didn't realize I put all the sentences in the same tense. So the first example would be わかい時、ただしさんのお父さんはかっこういかったと思います and the second example should be 九時にコンサートをはじめたと思います right?

 

[Toritoribe]

いい conjugates a bit irregularly.

いい
よくない (negative)
よかった (past)
よくなかった (negative past)


はじめる is transitive, whereas はじまる is intransitive. コンサートをはじめた means you started the concert.

かっこいかった may be acceptable, but I'm pretty sure かっこよかった is more common. Otherwise it looks pretty good. イケメンだった or something like that may be a better word choice, but it's a well-formed sentence otherwise.

Your English sentence says "I think the concert began at 9 o'clock," but your Japanese sentence says 九時にコンサートをはじめたと思います. Do you see the difference?

[Edit] Well... I was a little late on this one. Oh well...
