6. She scared at a lizard.
7. She was scary at a lizard.
8. She was scary to a lizard.
(What about the four sentences? Which ones are OK?)

Answer 1

1) The movies was scary
3 & 4 both correct
5 & 8 sound the best

Answer 2

Scary is an adjective modifying the subject. Scared is a verb.

5 would be better as "She was scared by a lizard." It indicated that she was frightened.

8 indicates that the lizard was frightened.

A similar relationship exists with 3 and 4. In 3, they were frightened, and in 4, he was frightened.

I hope this helps a little more. Thanks for asking.
