I want to emphasize one point for you. I hope it will be useful to you. Generally speaking, if you want to happen, take place, appear... this kind of momentary verbs (transient verbs, continuous verbs) are placed after see because they use prototypes. Such words are completed in an instant, and of course what you see is the whole process! Isn’t that right? If "see" is preceded by "often" and followed by the original form of the verb, don't forget the above rules! ! (This test site is very common in junior high schools, but rare in high schools)
