✔ 最佳答案
Answer: sent (present tense)
We use the simple present tense to talk about:
(1) things that are true now, e.g. My name is Susie. I am twelve years old.
(2) how often we do things, e.g. Susie and Betty go shopping every Saturday morning. They usually buy a lot of things.
(3) Things that are always true, e.g. Owls have two wings. They fly very fast.
