Take my word means believe me just because I say so. Meaning, you take my word as the truth without questioning it.

"be going to do" isn't a proper way to say anything. I'm going to assume you mean "going to do" Be doing... I assume you mean as used in this sentence, "What is John going to be doing tomorrow night?" Be doing here is the same as "going to do" You could rewrite the sentence, "What is John going to do tomorrow night?" and it means the same thing.

Job is a noun. I have a job. I love my job. Work is a verb. I have to go to work. I love the work I do.

Yes they are correct.. but I don't understand the purpose of the sentences. The only one that doesn't sound 100% correct is I just don't understand how this happened in such a place. I feel like "such a place" needs another word to describe it. Like "such a nice place" or "such a bad place"

Chew up would be to chew up something until is it gone or demolished. Chew on is something ongoing like gum. You chew on gum, over and over and over and it doesn't get destroyed.

It is asking, "what's going on?" or "what is all the activity?". Fuss is typically like a disruption, or a crowd of people gathered.

1) call a taxi - I find an open section of sidewalk and face oncoming traffic, raise my hand high above my head and yell "TAXI!" if I see a taxi with the little light on the top of his car on. That means that he's working and doesn't have anybody in the car.

2) call a waiter/waitress - I typically try not to "call" a waiter or waitress. In the USA, they will come to you. But if you HAVE to call them for something important and you can't wait. Typically I just wait until they come into view and I make eye contact with them. Sometimes I just nod my head or slightly lift my hand and smile. They will know I need something.

3) show you think something/someone is crazy - That depends. If it is a friend I tell them "You're CRAZY!" and laugh. If it is a crazy person I do not know, I just try to get away or end the conversation. No one wants to talk to a crazy person.

4) indicate number- I do not know what you mean here. If you mean a number of people, you can count on your fingers and show them in the air. But I would need more explaination on this one.

5) show that there is a phone call - If someone is speaking to me and I am on the phone I will hold up a single finger to tell them to wait a second and show them the phone that may be hidden in my ear. Or if I have to show someone across the way that there is a phone call you can make a "phone" with your small figer and your thumb and hold it up to your mouth/ear to mimick holding a phone.

6) show that you want a drink- I don't often have to SHOW someone I want a drink. I would tell someone I wanted a drink but the symbol that is widely accepted would be miming holding a drinking glass and lifting it to your lips.

7) show you don't mind- Usually a swipe of the hand will do. Up and down or left to right, it doesn't matter. Just basically "swat" the idea out of the way that it was any problem for you.

That is a hard question for me to answer. I can use them properly in sentences myself but explaining them to another person is difficult. Would is related to "will" "I will go after class to get ice cream" and "I would go after class to get ice cream if I had the time." "Could" has to do with "can". Meaning permission or ability to do something. "I can go get ice cream because I have 10 minutes before class" and "I could go get ice cream if I had 10 minutes before class." Lastly "might" means "may", "it depends", "unsure". "I might go get ice cream after class if I'm hungry." I hope that helps. Or someone smarter and more experienced in explaining closely related signs on and speaks up.
