"Bullshit" is an idiom, meaning it's literal translation doesn't mean the same as what people who speak English use the word for. To call something "bullshit" means that it's invalid, unworthy, untrue, etc. "His excuse that his dog ate his homework is bullshit." "I was fired from my job because I was 5 minutes late one time--that's bullshit." Keep in mind that "bullshit" would be classified as cussing, so I wouldn't use that when speaking with your grandmother!

The word "use" here is meant to convey the idea of "benefit from the use of." You could also say, "I could go for a nap." Same for, "I could use a drink." In the sentence, "I could use a nap," pronounce the word "yuz;" in the phrase, "benefit from the use of," it's pronounced "yuse."

4. Yes, what Eliot said. "You can bank on it," would originate from the concept of betting on something and it's like the person is saying, "You can bet on it," because it's assured. 5. You're correct, Hailey, this is very odd word choice and is actually incorrect. The word "much" is used in the sentence to describe the number of movies the person bought, and "much movies" is incorrect, it should be "many movies" or, "as many of her movies as I could find." The easy way to learn which word to use is to determine if the word (noun) being modified by the adjective (many/much) is a countable item; that is, if you can say "15 movies," you need to say "many" rather than "much." You would say, "How much money do I need?" because you can't say, "15 money," but you would say, "How many dollars do I need?" because you can say "15 dollars." You would say, "I have so much news to tell you," because you can't say "3 news," but you would say, "I have so many news stories to tell you," because you can say "3 news stories." If the noun is an actual countable item, use "many;" if the noun is not a quantifiable, countable number, use "much."

1. I kind of agree with Eliot, but I think more explanation is key here. The word "mark" in the expression, "Mark my words," is almost like a figurative expression meaning, "highlight," or, "take particular note of." "Mark my words," is an expression often heard when someone's upset and says a threat, something like, "Mark my words, Jonah, I'll hurt you." It doesn't just mean that the person's telling the truth, it's also an expression to let the listener know he or she better not forget what's being said--it's important! 2. I don't think you've given enough context here to accurately give an answer. The expression doesn't really make sense without additional detail--can you offer more information? 3. "Loop" doesn't only refer to a group of friends doing business. If you, "Cut someone out of the loop," it could also mean that you're no longer going to keep that person informed with the most up-to-date information that you're giving other people (you can say that you're, "Out of the loop," if someone asks you what the problem is between your brother and sister and why they're fighting, for example, if you don't know why).

While I agree that both are important... Voice chat is a great way to learn intonation, pronounciation and idiocynracies that are so unique to English, but because we have so many odd grammar rules and spelling difference, you absolutely need to chat by typing/writing, too.

It's slang for, "Nothing." You could say, "Nada," in response to the question, "What are you up to?," "What do you want?," or something like that.

The T in "water" and "motor" and "a lot of" should (typically) be pronounced with the tip of your tongue against the back of your top row of teeth. This is called an "unvoiced consonant" (you're pronouncing the word by forming your tongue and exhaling air, not by vibrating your vocal chords). In many dialects, however, the T can sound like a D for many words (like the example Robert gave). Because English can be spoken very quickly and words run together, or sounds are compromised, "water" can sound like "wadder," and the listener wouldn't question that--you sound normal saying "waTer" or "wadder." When the T sound turns into a D sound, it's then called a "voiced consonant," meaning you're still placing your tongue in the same position, but instead of exhaling air to make the sound, you vibrate your vocal chords. Many consonants have letters that can demonstrate this: B is a voiced consonant when you vibrate your chords to make the B sound in "begin." P is an unvoiced consonant because you don't vibrate your chords to make the sound of P in the word "supper," but you form your mouth the same way for each letter. You also form your mouth in the same way for each of the following voiced/unvoiced pairs: V is voiced because you vibrate your vocal chords, as when pronouncing "victory." F is unvoiced because you exhale and don't vibrate your vocal chords when pronouncing the word "family." G is voiced because you vibrate your vocal chords, as when pronouncing "gone." K is unvoiced because you exhale and don't vibrate your vocal chords when pronouncing the word "kite." Z is voiced because you vibrate your vocal chords, as when pronouncing "zebra." S is unvoiced because you exhale and don't vibrate your vocal chords when pronouncing the word "silly."

When talking about the difference between two things, Xiao, you'll want to ask, "What's the difference between 'let go' and 'move out of my way,'" (instead of "from," use the word "between"). At first, I thought you meant, "Let go," like, "Let go of my hand," which means, essentially, to stop holding. If you mean, "Let the car go," though, or if you're trying to express the thought, "Let him/it/her/them pass," then you need to use a direct object (that is, "let" in this context means "permit," and it requires a direct object so that the listener understands what you want the permission granted to). "Let the car go," would be a friendly but direct way to tell someone to permit the car to pass. This would be directed at someone who has the authority to open a gate on a street, for example. "Move out of my way," is a more aggressive way to tell someone whose body is blocking your path to move--and to do it quickly! I hope that helps.
