I had a cold yesterday. Mum took me to the hospital to see a doctor. I took some medicine for a cold. I'm fine today and went to school.

（1）have 表状态，不是一时的动作，改成caught 才对；

（2）for a cold 说 for my cold 可以；前文已经说了是感冒，还要吃别的药么？

（3）划线的这两句，不能用and连，做成两个分句可以：I'm fine today. I went to school.  然后是。。。

（4）因为你是写便条, 你得顺着时间流向这顺序，否则就怪了

-----------------写便条-------上学--------------------->

I felt better today so I decided to go to school. …

I felt better today so I needed to go to school. …

Today, I felt better and I decided to go to school. …

Today, when I felt better and I decided to go to school. …

## feel better是康复后常用的话，可能全好，也可能是好转

I got well and go went to school today.

注意，你不能说 I go to school today. (X)
