Hello Beligma! Thank you for your answer. Do you remember our Dr. SPOM's scheme (Subject, Predicate, Object, Modifier)? It IS all (that) I wanted to say.  And do not forget the constructions "there is, there are" - In Canada, there are a lot of foreign students... And it is better to put "too" at the end of a sentence (a part of a complex sentence). All in all, I like your efforts. Each piece of writing leads you closer to your success on the exam)
