I just need help with 2, 4-7

2. My sadness made me feel submerged and drowning, sinking low into a depth of darkness; similar to a submarine on an underwater recovery.

4. The basketball player was clearly a pro; he stood as tall as an oak tree!

5. I could sense his presence. I could smell his presence. The intruder, carrying a foul stench that radiated; just as a lockerroom radiates with smells full of sweat and grime.

6. The sneeze was so big! It was like a blue whale hitting back down into the water after a massive jump.

7. The movie was so boring, it was as if I were sitting through hours of watching paint dry. It's like I was watching molasses fall!
