Actually, I like science and scientific lectures as well. I often watch them on Youtube (generally TED) or on Facebook. I subscribed to some specific groups for that.
I like to know something new even if I'm not a specialist in this theme and can't fully understand the topic.
I also buy some journals about science and travel. And I never throw them in the bin, despite they occupy someplace on my shelves.
And of course, I often watch my favourite TV channels - Discovery, National Geographic and Animal Planel

Nop I haven’t, well when I was a kid I used to enjoy biology classes but I didn’t like physics or chemistry classes as I think I’m not good enough solving math problems. But I am steel interested on biology and how the body works inside, it’s a fascinating subject. I really like animals and I’d have liked study veterinary medicine but I’m in love with culture, history and so on.

Hello members of The LearnEnglish Team!
I have studied the grammar rules given in this website but i have not been able to find advanced level rules. I would like to know if it exists.

Hello BobMux,

We still haven't finished the Advanced section, but you can find some advanced-level grammar points in the Grammar reference. Not all of the pages there have an advanced section, but some do -- for example, the Present tense page.

All the best,

I never watched talks like this neither scientific lecture online, but I watched them on tv and at school. On tv I saw, not a long time ago, an interesting program about the discover of electricity and the progress that human beings have made during ages using it.

Scientific lectures are not the first thing that comes to my mind. However, there are specific topics that I have an interest in. I enjoy talks about how the wires of our brain determine our behaviour, as long as the language used is not too technical because I'm not proficient in science.

Of course. I love biology so much, when I was in school, I always hoped anxiously the class biology because I had a great teacher who taught me very good. She always taught me about DNA and cells. And then I was very interest about it that I studied a career related to biology and health. I remember every day I wrote on my board about biology topic as DNA conjugated, cells, viruses, cell theory among other topics. I love a lot biology because you can find a lot of things about nature, your body, your cells, things that happened in the past or will happen in the future. For sure, it’s a very interesting subject which you can find out and know more about what happens inside of you.


Sometimes, although I am not that interested in scientific lessons , but I like to watch few of them every once and a while .

Yes. I does.
