It might seem simple but of course the fastest way is to practice speaking as much as possible. I assume that maybe you don't have people to speak to which is when this becomes difficult. If you are unable to speak to those around you or to take an online class, then the main thing is to immerse yourself in other English sources. Watch TV & movies in English with no subtitles, read the newspaper in English every morning and an English book or novel every evening. Listen to English Podcasts or audiobooks when you are out and about. All of this will improve your listening, grammar, vocabulary and pronunciation skills over time and in a short period give you topics from the news that you can discuss while also improving the listening side of your conversation skills. While doing all of this, try playing one side of the conversation of TV shows you are watching, give short speeches on topics from the news and practice reviewing the books or movies you are watching out loud. Try recording yourself to see how you sound compared to those in the movies. It is hard when you don't have anyone to speak to, but it can be done. Good Luck.

First of all, " he is never ever watch that before." is incorrect. You should say "he has never seen it." Secondly, you wouldn't say "go to watch it" or "go watch it", mostly because it's a little rude and it would be more polite to say : "you should see that movie, it's awesome!" or "that new HP movie is awesome, you've gotta (got to) watch it" Finally, your last question also needs correcting: Is there another way to say? should be "is there another way to say this?"

While the 3 words can have different meanings, in this context they all mean the same thing. EG A: Where is my chocolate? B: I ate it! A: What!!! You ate it? I'm going to kill you! B: woah, calm down, I'm only joking/kidding/teasing. It's also worth noting that joking and kidding are intransitive while teasing can be transitive. IE "I'm just teasing you" is ok but "I'm kidding/joking you" is not okay, you would have to say "I'm just joking with you."

The third one is correct. Based on the start, the person will be arriving in the future, so it can't be the first one. Since you don't know, you can't use 'will'. Then, should can be used since it is not certain, IE you don't know when
