About Subjunctive Mood

[hirashin]

Dear native English speakers,
Would the following sentences be correct and natural?
1 If it were not raining, I would go shopping.
2 If I had twenty million yen, I would buy a Porsche 911.
3 If Tom were American, he would speak English more fluently.
4 If I were a doctor, I could help you.
5 If I had a car, I would pick you up.
6 If it hadn't rained yesterday, I would have gone shopping.
7 If I had been there with you, I could have helped you.
8 If you had boarded that flight, you might not be alive now.
9 If you had come to the party yesterday, you could have met Mary.
10 (a) If I had left home at six, I could catch the train.
(b) If I had left home at six, I would be able to catch the train.

Thanks in advance.
Hirashin

I think they're all ok and natural (of course to be really conversational, I'd use contractions e.g. If it weren't raining I'd go shopping). For (10) it sounds like it's after 6 but before the train has left. If the whole event was over, the second clause should be past tense too. e.g. If I had left home at six, I could have caught the train.

Thanks for the help, mdchachi. Yes. You're right. I made mistakes in 10a and 10b.
