Všechno začíná u Simple Present - nejzákladnějšího času v angličtině. Vytvoříš ho jednoduše: u třetí osoby jednotného čísla (he, she, it) přidáš ke slovesu -s, jinak zůstává sloves v základním tvaru.
Zápor tvoříš pomocí do/does + not, otázku pak do/does před podmět. Například: "Does he speak?" nebo "He doesn't speak."
💡 Tip: Signální slova jako always, often, usually, never ti prozradí, že máš použít Simple Present!
Tento čas používej pro pravidelné činnosti, obecné pravdy nebo události podle jízdního řádu. Je to tvůj nejčastější společník v angličtině.

Present Progressive poznáš podle toho, že právě teď něco děláš. Tvoří se pomocí am/is/are + sloveso s -ing. "He is speaking" znamená, že právě v tuto chvíli mluví.
Signální slova jako "now", "at the moment" nebo "Look!" ti napoví, že jde o současný děj. Používej ho pro věci, které se dějí právě teď nebo v tomto období.
Simple Past je pro věci, které se staly v minulosti a jsou hotové. U pravidelných sloves přidáš -ed, u nepravidelných musíš znát jejich tvary.
💡 Pozor: Yesterday, last week, in 2020 - to jsou jasné signály pro Simple Past!
Zápor tvoříš s "did not" a otázku s "did" - například "Did he speak?"

Past Progressive je jako Present Progressive, jen v minulosti. Použij was/were + sloveso s -ing pro děje, které právě probíhaly v nějakém okamžiku v minulosti.
Perfektně funguje s "while" - zatímco něco probíhalo, stalo se něco jiného. "While I was studying, my phone rang."
Present Perfect Simple je trik - vypadá jako minulost, ale vlastně mluví o přítomnosti! Vytvoř ho pomocí have/has + 3. tvar slovesa.
💡 Důležité: Present Perfect používej, když výsledek minulého děje je důležitý právě teď!
Signální slova "already", "just", "never", "yet" jsou pro Present Perfect jako stvořená. "I have just finished" znamená, že jsem skončil a je to důležité teď.

Present Perfect Progressive kombinuje Present Perfect s -ing koncovkou. Have/has been + sloveso s -ing používej, když chceš zdůraznit, jak dlouho něco trvá až dodnes.
"How long have you been learning English?" - ptáš se na trvání děje až do současnosti. Signální slova "for", "since", "all day" ti pomohou rozpoznat tento čas.
Past Perfect Simple je "minulost před minulostí". Když vypravuješ příběh v minulém čase a chceš říct, co se stalo ještě předtím, použij had + 3. tvar.
💡 Představ si to: Příjdu domů (Simple Past) a zjistím, že už někdo snědl moji čokoládu (Past Perfect)!
"Already", "just", "never" v minulém kontextu jsou signály pro Past Perfect.

Past Perfect Progressive je nejsložitější, ale logika zůstává stejná. Had been + sloveso s -ing pro děj, který probíhal před nějakou minulou situací.
"I had been studying for hours before the test started" - učil ses dlouho před tím, než test začal. Zdůrazňuješ trvání té činnosti.
Signální slova "for", "since", "all day" v minulém kontextu ti napoví, že jde o Past Perfect Progressive.
💡 Zlaté pravidlo: Ptej se sám sebe - chci zdůraznit výsledek, nebo průběh děje? To ti pomůže vybrat správný čas!
Pamatuj si, že každý čas má svůj účel. S praxí ti bude výběr správného času přirozený jako dýchání.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend
