Mrs. Wilson,

I’m going out shopping, and won’t be back until about 5:00 pm. I have taken with me the two books you asked me to return to the City Library. At about 1 o’clock this afternoon, Tracy called, saving that she couldn’t meet you at Bolton Coffee tomorrow morning as she has something important to attend to. She felt very sorry about that, but said that you could set some other time for the meeting. She wanted you to call her back as soon as you are home. She has already told Susan about this change.

I Want to Smile

参考范文：

One Possible Version

There are many advantages of smiling. It can not only make us happy, but also please others. If we smile at life, life will smile on us in return. So I want to smile at all whenever and wherever possible,

First, I would like to smile at my parents because they have given me life and take all the trouble to bring me up. They arrange almost everything for me. With their help, I have made great progress. I would like to say “Thank you” to them with a smile. Then my smile should go to myself, for only in this way can I gain more confidence in smiling my troubles away and live a better life. 　

In a word, let’s greet every day with a smile. Tomorrow is another day. 　Ks

Green Action in Our Class

April 12 is memorable because our class had a meaningful experience on that day. In the morning, we bicycled to the suburbs to plant trees, talking and laughing all the way. Upon arrival, we began to work immediately. Some were digging holes. Some were carrying and planting young trees. Others were watering them. After getting the work done, we put up a board reminding people to protect the trees. Before leaving we took some photos to record our green action. Seeing the lines of trees, we all had a sense of achievement. We feel it's our duty to protect and beautify our environment. 　

第二节 开放作文(15分)

One possible version:

What an interesting picture! A Western young man, sitting at a table, is ready to eat a bowl of noodles. He is holding two forks the same way as we Chinese hold chopsticks. He is trying so hard to pick up the noodles that he is sweating a lot. At first glance, I think it's a bit funny, for we Chinese take for granted that chopsticks are the tools for eating noodles. The man in the picture is trying to copy us. Obviously he is doing it the hard way. Maybe using one fork will do a better job. In my opinion, we don't need to copy other's ways of thinking. Sometimes a simpler way of doing things may be a better way.

One possible version

Good morning, Ladies and gentlemen.

Some of us are having problems with our parents, as they often look into our school bags or read our diaries. I fully understand why we are not comfortable about it, but there’s no need to feel too sad. Our parents are checking our bags or diaries to make sure we’re not getting into any trouble.They have probably heard some horrible stories about other kids and thought we might do the same. Or perhaps they just want to connect with us but are doing it all wrong. My suggestion is: Tell them we want them to trust us as much as we’d like to trust them. If you don’t think you can talk to them, write them a letter and leave it lying around – they are bound to read it.

Thank you!
