1. If you miss the class I take you some
2. When I see Sandra, I ask her what she thinks.
3. We have time for lunch if the train leaves at 12 o'clock
4. If I ask my boss for a pay raise, he will not give it to me
5. I cook dinner if you do the shopping
6. If the weather be nice, we go out for a walk
7. We go on Holiday when Al get some time of work
Some good ideas are blossom, parallel, taxi, carnivore, gift, and miscellaneous.
Two sentences joined with a coordinating conjunction and a comma form a compound sentence. If it were a complex, it would have a dash. If it were a comma splice, it would have a dash and a dash. If it were a run-on, it wouldn't have either, just a lot of and in it.
Hope this helps. :D
