Předpřítomný čas (Present Perfect) je jako most mezi minulostí a přítomností. Používáš ho, když chceš říct, že něco začalo v minulosti, ale má dopad na současnost.
Tvoření je vlastně jednoduché: have/has + příčestí minulé. Pro I, you, we, they používáš "have", pro he, she, it pak "has". Například: "I have finished" nebo "She has arrived".
Tip: Pokud si nejsi jistý, jestli použít have nebo has, zeptej se sebe: "Kdo to dělá?" Pokud je to 3. osoba jednotného čísla , tak has, jinak have.

Některá slova ti přímo napovídají, že máš použít předpřítomný čas. Mezi nejčastější patří already (již), just (právě), never (nikdy), ever (někdy) a not yet (ještě ne).
Další užitečná slova jsou so far (dosud), till now a up to now (oba znamenají "až dosud"). Když některé z těchto slov ve větě uvidíš, téměř jistě půjde o Present Perfect.
Zapamatuj si: Tato slova jsou jako červené vlajky - okamžitě ti signalizují, který čas použít.

Důraz na výsledek je nejčastější použití. Nezajímá tě přesně kdy, ale že se něco stalo: "I have cleaned my room" (výsledek: pokoj je uklizený).
Právě dokončený děj často doprovází slovíčko "just": "He has just played football." Používáš to, když něco skončilo před chvilkou.
Pro děj trvající až dodnes použiješ často "since" nebo "for": "We have lived in Germany since 2000." A konečně pro zkušenosti: "I have been to New York recently."
Pozor: Nikdy nepoužívej konkrétní čas v minulosti (yesterday, last week) s Present Perfect!

S pravidelnými slovesy je to snadné - prostě přidáš -ed. Watch → watched, play → played, clean → cleaned.
Kladné věty: "I have watched TV", "You have watched TV", "He has watched TV". Záporné věty: přidáš "not" po have/has - "I have not watched TV".
Otázky tvoříš přehozením: "Have I watched TV?", "Has he watched TV?" Je to stejný princip jako u jiných časů s pomocnými slovesy.

Nepravidelná slovesa jsou trochu komplikovanější, protože si musíš zapamatovat jejich speciální tvary. Read → read, go → gone, see → seen.
Struktury vět zůstávají stejné jako u pravidelných sloves. Kladně: "I have read a book", záporně: "I have not read a book", otázka: "Have I read a book?"
Nejlepší rada? Vytvoř si seznam nejčastějších nepravidelných sloves a jejich tvarů. Postupně si je osvojíš používáním.
Hack: Mnoho nepravidelných sloves má stejný tvar pro minulý čas i příčestí .

Pravidelná slovesa se řídí jednoduchým pravidlem -ed: watch → watched, play → played, clean → cleaned, work → worked, talk → talked.
Nepravidelná slovesa si musíš prostě naučit: read → read (pozor na výslovnost!), go → gone, see → seen, do → done, write → written.
Zapamatuj si rozdíl: u pravidelných stačí přidat -ed, u nepravidelných musíš znát specifický tvar příčestí minulého. Bez tohoto základu se předpřítomný čas nenaučíš.

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

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

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
