1. When I was going to school, I used to see an old friend.

(Mistake: "returned" should be "were returning" to match the verb tense of "was still working".)

(Mistake: Adverb "rarely" should come before the verb "spend" for correct sentence structure.)
4. Delivery is usually within three working days of your order being placed.

(Mistake: "after" should be "before" for logical meaning.)

(Mistake: "in warming state" should be "warming" for correct phrase usage, and "stopped" should be "stop" for verb tense consistency.)
8. When a species of plants or animals is in danger of extinction, it is gradually disappearing.
(Mistake: "are" should be "is" for subject-verb agreement, as "a species" is singular.)
9. As soon as the snow melts, spring wildflowers push their way up through the leaf litter.
(Mistake: "will melt" should be "melts" for correct conditional structure.)
