Is it correct to use present tense for the verb "notice" when talking abt sth in the past? I read an example as follows on a sentence structure book but I wonder why the verb "notice" is in present tense instead of past tense or present perfect .... The sentence , "I notice that he has taken your umbrella by mistake. " Under what situations can we use present tense this way? I can understand other examples like "She remembers that she has seen the stranger before.", or "The article says that many people were killed in the earthquake." But have difficulty in understanding the above example of "notice".... Thank you very much !

Only "champion" can be said as "winning" the competitions? I'm doing a comprehension exercise right now. There's a poster about a pianist. The poster mentions that the pianist has been : 1) the winner in 2011 London International Festival 2) the first runner up in 2012 All-Asia Piano Competition 3) the champion in 2014 Vienna Piano Competition then there's question asking , "How many competitions has she won?" I'm wondering whether I should answer 2 or 3 since I'm not sure if I should count the "first runner up" as winning too? (I've googled but it's not clear as there're also some phrases like " has won many titles ....". So if in general speaking, like the question mentioned above, how to define or use the phrase " winning a competition" ? Thank you so much for your help!

"our monthly excursion" Writing practice : joining 5 words : exhilarating, excursion, recreational, novelty, wearisome welcome corrections or suggestions. Thank you for your help! The passage: My brothers and I are looking forward to the weekend excursion arranged monthly by our father. We believe this coming trip will be just as exhilarating as before/the previous ones. Last month, our father drove us to an newly-opened campsite which provided lots of outdoor recreational facilities. The campsite even had a small brightly-coloured wooden kiosk where you could find various novelties and a collection of poetry picture books . Our mother sometimes thinks these trips are very wearisome and she would rather stay home and take a rest. For us however, the novelty of these monthly trips has never diminished.
