yes it can. eg the neighbors think Mary is smart because Mary wears a uniform to school :}
The books don't really describe a uniform. In the films, the uniform consists of a standard boarding school uniform with a black cloak worn over it. The colors on the tie indicate your school house. Also, your house's logo is emblazoned on the left shoulder of the cloak.
In school, Mary thinks math is the worst subject because of fractions.
There is no predicate adjective in that sentence. In order for a sentence to have a predicate adjective, the verb must be a linking verb. Example: Mary is happy. ("is" is a linking verb, and "happy" is a predicate adjective) In the sentence "Your sister Mary teaches math and physical education at the high school", the verb (teaches) is transitive (a type of action verb that takes a direct object).
It depends on the school you attend. If your school has a uniform policy in effect than whatever you wear must abide by that policy, including your shoes. However if you attend a school without a uniform policy than by all means feel free to wear any pair of shoes you desire... so long as they are appropriate.
Being Jewish, I was somewhat confused that I had been enrolled in Saint Mary's High School.
Mary Rose School was created in 2007.
It is capitalized at the beginning of the sentence or when it forms part of the proper noun. Examples: It is the normal school for girls. Mary studies at Philippine Normal College.
The sentence "Is Mary not Happy" is correct grammatically as a question. It defines Mary as the subject and not happy as the object. In the other sentence, though grammatically correct, it could be confusing. Not Mary could be construed as all people but Mary. I would use the first sentence, as it is clearest.
Mary McConnel School was created in 2003.
