Adding stress to words in a sentence can entirely change the meaning of a sentence. It's incredible, really. So we've got: I'M not going out this evening. (You're not going out, doesn't mean others aren't.) I'm NOT doing anything this evening. (stress on refusing to do anything) I'm not DOING anything this evening. (Someone's implied that you are, perhaps) I'm not doing ANYTHING this evening. (More like a lot of stress on how they'd say it with this one, it could mean an angry tone, annoyed, tired, fed up etc. It'd be an exclamation of the fact that you really aren't going to do something, stress on how) I'm not doing anything THIS evening. (You aren't doing it in that time frame, stress on that day, point of that day.) I'm not doing anything this EVENING. (stress on time) For another example think of this: I didn't say to wear that = someone else said to wear that I DIDN'T say to wear that = denying that I said to wear that I didn't SAY to wear that = I implied it I didn't say to WEAR that = I said throw it/burn it/cut it up I didn't say to wear THAT = You should wear something else

Driving to a waterfall.

I drove to Fukurodanotaki yesterday, (better if you put yesterday here, the sentence becomes less confusing and isn't so choppy) which is one of the three most famous waterfalls in of Japan yesterday. On the way, I bought a lot of vegetables at a farmers market. I'm very busy to take care of those vegetables to ready for cooking or to freeze them in the freezer.

 

"I'm very busy to take care of those vegetables to ready for cooking or to freeze them in the freezer." Not entirely sure where you're trying to go with this last sentence, were you trying to say that you're too busy to take care of the vegetables, so you had to put them in the freezer?
