This question is not like another duplication question.
I'm confused that someone explains the quiz question about example of "recommend". There are 5 examples of sentence which is used with "recommend".
- I recommend you to visit Gyeongju.
- I recommend you visiting Gyeongju.
- I recommend visiting Gyeongju.
- I recommend (that) you should visit Gyeongju.
- I recommend (that) you visit Gyeongju.
She said only 3 and 5 are correct number. I am very familiar with number 4.
Does she's answer correct? only 3 and 5 are correct? Can't use "should" when I write with "recommend"?
