June's parents parked their car in the zoo's parking lot.
June got out the car, and ran towards her friend who was wearing an animal mask. (disguised doesn't sound natural)
All of her friends were there to celebrate her birthday! The group began to visit the zoo first seeing the lions and panthers.
They are big cats with big teeth (teeth is the plural of tooth). Lions have a beautiful mane that used to charm lioness. (I didn't understand the last sentence)

Not is used with any sentences using do. (Do not touch the paintings.) No is used with imperative commands with -ing. (No sleeping in class) No is also used with questions. (Are you going out tonight? No.)

I want to participate in a workshop that meets by our university but I can't prepare any work for it. I am afraid that I can't finish my article before the deadline so I will be working hard to finish my article.
