a story
one day i saw a boy falling off from a tree, when i was coming home from school.i felt so scared, so i call the ambulance quickly. then it came and sent the boy and i to the hospital soon.
when the boy was treated, i called his parents.(這里有點(diǎn)奇幻啊··怎么就知道他父母的電話捏~~)
his parents were very hurry. when they came, the boy was sleeping and was fine.
差不多70了吧 不夠自己再添點(diǎn)
過去進(jìn)行時(shí),可以適當(dāng)用些when引導(dǎo)的時(shí)間狀語從句,表示某個(gè)時(shí)間點(diǎn),誰正在干什么.
