The 3 of them all have really similar meanings, so it's actually kinda difficult but I would actually rank them in terms of use Infinite > Innumerable > Myriad Myriad to be fair is a pretty advanced word that a lot of native English speakers aren't going to know the meaning to off the top of their heads (I've used this word many times in a training setting with fluent English speakers and had them asking me what exactly I meant) Most of the time I would opt to use infinite and put something in front of it to give the meaning I'm looking for "near infinite" would be roughly the same as innumerable (Innumerable as a word implies that there is a limit, we just don't know what the limit is, infinite is implying there is no limit). However, I would say from a number perspective you could use myriad in any scenario where there are many options (In this instance, you could substitute myriad for many), I would use innumerable or infinite more or less interchangeably but would need to read the room as to who I'm speaking to, innumerable isn't going to be as commonly understood as infinite -- despite the two having a near identical meaning (I would actually say innumerable would hit a little harder given it sees less use in day-to-day speaking so I would use that over infinite if I really wanted to stress how many options there were of something)

Must 1. Using must here makes it sound as though it's mandatory, you're required to do so. This sounds a little weird by itself, you could put "In this house, we must brush our teeth twice a day." to make it sound like a rule that's been enforced. 2. This works fine, it's a rule on the train that you can't do it (Which it isn't necessarily a law, but any Train company could state that you can't do it) 3. This is a great use of must, it works really well here. Have to: 1. Perfect 2. This does work but it sounds a little strange, but I'd probably change the sentence to something like "Do you really have to fly to Spain for work?" 3. Great use of have to here. Should 1. The use of should works but the sentence sounds a little strange. I'd change the sentence to something like "You should study more if you want to get high marks in this Exam" 2. Great use of should here too, though much should be replaced with many "I shouldn't feed too many snacks to my hamster" 3. This is a perfect example, well done :)

Yep, this is a great example of pushing it. To say that the idea of putting pineapple on pizza is ridiculous/weird/strange (which is the connotation of it used in this example). I would remove the 'even tolerate ketchup' to make it sound more natural imo. "Wait, you put pineapple on Pizza? I can understand ketchup... But Pineapple? That's pushing it." One of many ways it could be said, but your example absolutely works too. :)

A lot of pretty advanced colloquialisms here. To get dragged is to be humiliated, embarrassed or disrespected (in this case, she's posted something on Twitter and a lot of people are making fun of her for it. It comes from the old saying 'dragged through the mud'.) To botch something is to do it poorly or to mess it up/not do it right. (An example of this would be "I botched the recipe", meaning that whatever I was cooking didn't end up looking or tasting very good) A 'burn' is a colloquialism for an insult, but there can be several types of 'burn' that depend on the context of the sentence, who you're talking to (For example, if I try to 'burn' my friend, I'm either insulting them or playfully making fun of them with a lighthearted insult. Based off the fact they're my friend, you can likely assume that it's a playful jab/tease) So if you were to make this sound a little more... Gramatically correct (Though not nearly as interesting to read) it would read like 'Greta Thunberg embarrassed on Twitter after failing to insult Andrew Tate'

1. She whispered to her sister (Past Tense) 1. She whispers to her sister (Present Tense) To whisper is to talk very softly, you don't need to mention that you're talking here :) 2. He wanted to have a deep conversation with his new friend, but they left for another party 2. He wanted a good conversation with his new friend he'd made, but they were leaving for another party There are a couple of ways you can build this sentence, you've used present and future tense words in what I assume is a past tense situation (wants is future tense something that will happen later, but the new friend has already gone which means it's already happened). I think either of the two above sentences work, but the first one sounds a little more natural. 3. We bought some food for dinner at the shops near our house 3. We bought some groceries for dinner at the supermarket near our house Couple of different sentences here as well, the first one is more colloquial (Food instead of groceries, shops is a very colloquial term for a supermarket or a store) while the second one is a bit more standardised I think. 4. We unanimously decided to go to Switzerland 4. We all decided on a trip to Switzerland Good attempt on this one, I think if you're wanting to convey a feeling of absolute decision, then unanimously is a better choice. I don't think there's a way to make hesitate work unless you wanted something like "We didn't hesitate to choose Switzerland". 5. If the car is broken, I'll have to buy a new car The brand here is kinda irrelevant, we already know based on the sentence that it's going to be new and there aren't really different levels of new cards (You can't buy a kinda new car or a pretty new car, they're going to be USED cars) 6. Unless my teacher tells me, I won't do it. 6. I refuse to do it unless my teacher tells me. I don't think there's a way to introduce voluntarily into this sentence without making the sentence sound strange.

expressions

1. As a teacher, I know a thing or two the stuff about teaching. (<---- 'I know a thing or two' is a saying suggesting that you are quite experienced in the area. 'As a teacher' is redundant, if you know a lot about teaching we can assume that you're probably a teacher)

2.  Do you think I don't know about this? I wasn't born yesterday. (<---- 'I wasn't born yesterday is thrown at the end of the sentence rather than the beginning)

3. I was am on the ball more than you thought think I was. (<---- This sentence is indicating past tense)

4. I didn't exactly know where I stood after the interview with the interviewer (<--- We use this idiom when we are uncertain after an event has happened, in this case, the interview happened and now you're not sure if it went well, went poorly, if they liked you, etc. 'with the interviewer' is probably redundant, or should be mentioned earlier in the sentence or in a previous one to prevent reuse of the word 'interview' so close together.

5. For all I know, we are going to knock off early. (<---- Great. 'For all I know' is generally used when you have a lack of knowledge about something, in this case, you don't know if they're gonna let you off early or not, but you're assuming they will.)

If you have any questions about any of it, feel free to ask!

Binge is both a verb, and a noun, it's meaning is the same in both. For a noun you'd use it like this 'He went on a binge and couldn't drive home' in this case, we don't need to mention that he drank too much alcohol, by saying he couldn't drive home and saying he went on a binge, it is implied that the reason he can't drive home is because he drank too much. For a verb you'd use it like this (Which you already know how to use!) 'I binged on Ice Cream'

expressions

1. I went to the cinema with 2 other people. I felt like I was becoming the third wheel. (<--- I would personally write this like 'I went to the movies with a few friends ((or a couple as in, boyfriend and girlfriend)), I felt like I was the third wheel. Generally when we talk about being a Third Wheel in regards to the movies its usually because you're going with a couple ((boyfriend and girlfriend)) or some people who are really good friends, and you're an acquaintance ((or a friend, but not as close)). If you're going to use an idiom like "third wheel" I'd say you're talking in a pretty colloquial manner, so 'movies' would probably be used over 'cinema' as it sounds very proper.)

2. I shouldn't eat like a horse when I am with my boyfriend. He wouldn't like me gobbling food down. (<--- Be sure to mention exactly WHAT it is you're gobbling down, in this case it's food.)

3. Neck down the beer, you can do it mate! (<--- Well done lol)

4. I need to will do binge sleeping this weekend (<--- In a case like this, if you're binge sleeping, it's because you're exhausted after a long weekend. So you NEED to do it. It is important that you catch up on sleep, so you have to do it hence, why you are binge sleeping.)

5. Yesterday, I binged on food. Now that I've done it, I should feel guilty about it. (<--- Could go a few ways with this sentence you could say that you feel guilty because you binged on food yesterday when you shouldn't have. The other way you could go about it, is posing it as a question.
'I binged on food yesterday, should I feel guilty about it?')

Well done! If you need any more explanations please ask
