Hi, we can't use the present perfect with past time expressions, so both are wrong.

This is the second time I have talked about this interesting topic this month, because my electric car suprised me yesterday. I drove my car on a short trip yesterday. The place we visited only has one access road, which meandars around a mountain. I thought that it would be a challenge for an electric car, but in actual fact we got there very easily. When I checked the dashboard, it showed that it had only used 1.0 litre gas per 100 kilometres (actually my car is a hybrid car). It was a big surprise! When my car goes downhill, it is charged by gravity, when it goes uphill, the electricity powers my car. The computer system in my car is really good at using any power both from gas and nature. You know that when you step on the brake pedal in a moving gas-powered car, the extra energy from burning gas is spread into the air, which causes air pollution. But for a hybird car, the energy is collected and stored in the battery. The efficiency of using the extra energy for a hybrid car can be around 40%, But for a gas-powered car, all the extra energy wastes.So, which is better?

If there is one thing that should be taught in school, I think it's money management. Budgeting and personal finances are essential, but unfortunately many of us adults dont have the knowledge to manage our money correctly.

My level is B2 looking for casual conversation, and to talk on topics that interest me. During the conversation I want to be corrected on my grammar and pronunciation mistakes regardless of how many there are, instead of waiting for the end of the class to be corrected. If you also could type the corrections and send them to me later that’s a plus. This is how I teach. Check out my profile and book a trial if you see fit!

I would say as a gerund I am busy swimming I am busy doing the dishes doing - some action or activity = verb in the ing form = gerund :)

The picture looks like a different idion, 'the straw that broke the camel's back' 🙂

Great Adele song too!
