Howdy,
Could you please take a look at my sentences? I'm trying to learn new vocabulary, and here are the results:
1. At weekend I really like to use my free time in the morning and lie in a bit longer in the morning.
2. My laptop has gone off because I couldn’t plug in the charger anywhere.
3. Finally, I have cleared away the desk and put all the books in the drawers.
4. She has spilled the tea over the new carpet and couldn’t wipe it up.
5. Before you invite anybody, you’d better tidy your room up.
6. The lecture was so boring that I dropped off in the middle of it.
7. Don’t turn over, I’m waiting for the news.
8. Do you want anything from the green grocer’s? I’ll pop out and buy a few things.
As for examples 2, 3 & 4 I'm not sure whether the present perfect tense is used correctly and what the difference would be if I used simply the past simple tense. If somebody could explain me that, I'd be most obliged! Thank you.
