3．（10 分）Halloween was on Monday， 31 October． We had a whole week to celebrate． It was called the

Spirit Week．

On Friday before the Spirit Week， we were allowed to wear Halloween costumes to school． I dressed up as a

witch（女巫）． That was pretty fun! We got points for our class by dressing up．

We also had performances during the week ． Each class had a theme． We performed Alice's Adventures in

Wonderland． The performance included a dance and a skit（滑稽短剧）． I played the character of March．

Hare in the skit．

On Monday ， we arrived at school at 6 am to do our last rehearsal （排练）． I was so excited， even

though it was early in the morning and it was very cold outside ． We gave the performance in the main gym ，

and every student was there． I think we really did an excellent job! Although I only played a small role in the

skit， I was still proud and happy． I learnt much knowledge about acting by performing the skit ． The other

two classes performed on the following days during the Spirit Week． Their skits were also very nice．

Our hallway was beautifully decorated． Everyone's locker was painted with colorful pictures． The curtains

were hung below the light to make the hallways look dreamy． I liked it so much．
