Can you help me solve my grammar problems?

Now, it is your turn to answer questions. Since the people who posted answers all gave you different information, apparently they don't know anything more about it than you do, so did it help at all to post your homework and ask for free answers? Here's another one: When test time comes, will you be able to figure out the answers on the exam when you have not bothered to learn the material? If you did not understand the choices when they were explained in cl, the right thing to do is ask the instructor privately to explain it again. He/she usually has a "preparation period" of time spent alone in the clroom, and teachers are glad to help you learn to do these things for yourself. Parents force their young children to learn to tie shoes and on ons so that the child will ultimately be able to dress himself without help. You are asking others continually to help you with the "laces and ons" of grammar, and as long as they do so, you will never be able to get your "grammar" clothes on properly.
