Can my resume be two pages long?
No, a resume should never be longer than one page, especially towards the beginning of one's career. I cannot imagine a situation where a multi-page resume would be acceptable, or attractive to an employer.
Did you think we was going to leave you behind?
When speaking, phrases like "we was" may seem acceptable, but they are incorrect and should never be written. We were not going to leave you behind.
The first train took twenty-six minutes to complete the route, which ran from City Hall to West 145th Street in under a half an hour. Can this sentence be stated in a more simplistic manner?
Saying "in under half an hour" after saying "twenty-six minutes" is completely redundant. Many people have issues with redundancy when using the English language.
