［精美语篇]
Ms Li，our English teacher，must have found it strange on Teachers' Day：she did not receive a single
greeting card from us students。

She would have never thought a complete surprise was waiting for her。

With Teachers’ Day approaching，our class decided to hold a party to celebrate the important day for a change this year。

On the afternoon of September 10，some of us decorated our classroom with paper flowers and balloons，and others went to buy cakes，drinks and fruits。

The blackboard was decorated with beautiful words，which read “Happy Teachers' Day！”
Entering the classroom, Ms Li was surprised to find we were standing in line, clapping hands and saying loudly “Happy Teachers’ Day！" Wang Hua，our monitor，presented her with the prepared flowers。

Some of the girls sang songs for Ms Li，and three boys showed their kung fu talent。

Before we left，we enjoyed a new English song by Ms Li.
Ms Li spent a wonderful time with us，but we know that we cannot thank her enough for all her hard work and guidance。
