Hi, Jake,

How's it going? Sorry I haven't been in touch for a while, but I couldn't use my computer for a few days. You'll never guess what happened to me!

A couple of weeks ago, I decided to take up yoga. Yoga is  combination of physical and breathing exercises. _ 小题1: I've been feeling a bit stressed about my school work recently and I thought yoga might help.

My dad couldn't give me a lift to the first lesson, so I decided to go to the gym by bike.  The lesson was great and I felt really relaxed afterwards. 小题2:The next day , I woke up with a bad cold. I couldn't stop coughing and sneezing.  I couldn't go to school because I also had a high temperature. We were having a maths test that day so it was great that I could stay at home. I didn't really enjoy my day off though. I felt awful and stayed in bed. Mum brought me cups of hot tea for my sore throat(and you know how much I hate tea 小题3:    I have to keep taking these for a while so I can get stronger.

That afternoon Robbie came to visit me .He said he’d got something to cheer me up and pretended it was the math test that I missed."Mr Banks says do it at home instead ,”he said , but I knew he was joking. 小题4:   The next day, I was a bit pale and didn't have much energy, but I was feeling better. The day after that, I was able to go back to school.

Can you believe my luck? 小题5:

Anyway, you're OK. Write and let me know what you've been up to ! Bye for now ！

Kate
