1.When you hear High Rise Terminal (rising intonation at the end of a sentence) do you disapprove? Honestly, this may be stereotypical but I think it has sort of become an Australian sort of thing, but I am Australian myself and I've heard it so much around the streets. Even I unexpectedly use it too. Sometimes it just becomes a habit to end sentences with it. Really, it's not a bad thing to use in a causual with friends, it becomes bad when you're saying a speech at a conference or even in the classroom to your classmates and are constantly using the high-rising terminal, that's when it becomes very annoying and distracting. So I don't disapprove of it to SOME extent.
2. Do you think teenspeak is a form of standard or non-standard English? Why? I think teenspeak is a standard English when it comes to teens themselves but when it comes to the modern society, it is a non-standard English because it does not use the proper English sentence structure in some ways.
3. Have you been confused by teenage acronyms such as “LOL” and “ROFL? No, being a 17-year-old, I hear it a lot at school. I just find it funny when people actually say it "LOL" out loud but not actually laugh. It sort of annoys me but then I just end up laughing at it. Though, I prefer it if people use it in a written context because it sounds a bit better when speaking on MSN or Facebook rather than hearing it aloud.
4. Does the use of “gonna”, “wanna” and swear words in teenspeak lower your perception towards teenagers? (In reference to their status and education.) When having a casual conversation with friends, I tend to use the words "gonna" and "wanna" if I am speaking fast so no, they don't lower my perception towards teens but swearing DEFINITELY does. I really dislike it when people use derogatory terms, it just makes me cringe. Not only do they seem less educated but I just feel like some people really need to expand their vocabulary, especially if they constantly swear.
5. Do you think teen slang is teenagers being lazy, or does it’s use arise from necessity? For example, “ceebs” for can’t be stuffed. In that sense, yes teens are being lazy. If they use it in a spoken context, definitely they are. But if it is in a written context, not as much because I understand that writing all of the words may be annoying and seem to take time especially if you're a slow typer so written is fine.
6. Do you think the word “like” is necessary or appropriate? Why? I think that as a filler, the word "like" is okay to use but it can get annoying when people constantly use it as well especially if it is said using a high-rising terminal, it can get very irritating. But it also gives the speaker a millisecond (most likely more) to think about what they're going to say next.
7. Do you think teenage English is deteriorating standard English? Please explain. I don't think teenage English is deteriorating standard English because it is mostly a phase teenagers go through but they tend to lose it as they get older and get a career and speak in a more professional, formal register.
8. Give your opinion on the reasons why teenagers speak differently. I think teenagers speak differently because, being one of the youngest generations of the time, they feel the need to keep up the latest sayings are to try and fit in. For example, recently there were two phrases "whateven" and "awks" going aroung. Going to a girls school, I constantly heard it. At first, it was started off by the "popular" girls saying it then gradually, you would hear it pretty much everywhere. I think it's more of following what your peers are saying. Once teens enter the workforce, they will start to use their own career jargon and not so much focus on teenspeak as such so it's pretty much just a phase.
Hope this helped!

Not sure if what I said was biased because I am a current year 12 English Language student but I wanted to answer it because last year we had to ask people similar questions to these and I found it very interesting.
