I agree. I am finding a lot of the sentences in this lesson are just words strung together in a technically correct way, but not something anyone would actually say. It would be really helpful if they would start throwing in a few idioms (and noting them) so that we know when we're learning a useful expression as opposed to a silly sentence.
'As him' is incorrect. 'As' is a conjuction, unlike the preposition 'like', which is very often used as a conjunction (it is debateable, if this is correct use). Therefore it should be 'as he', since the 'he' replaces the subject 'you' and so is also subject. Do not be fooled by the English you might often hear (on tv at least), which makes numerous mistakes like this.
Nope. Sorry. It's a grammar rule. I am quite sure you will never say, "You play like I" or "You play like we". If you are not convinced, google it or check out these pages. http://www.grammar.cl/Notes/Like_vs_As.htm http://www.quickanddirtytips.com/education/grammar/like-versus-as http://cliffordgarstang.com/?p=3831 http://alt-usage-english.org/excerpts/fxlikevs.html
That's not true at all.
'You play as him' and 'you play like him/you play as he does' have entirely different meanings in English, and both are perfectly acceptable sentences depending on what you mean to say.
The only thing that can be taken issue with, is the fact we say "him" when technically we should say "he".
