0515考试

Your photograph recently won a photography competition and is now shown in an exhibition.
Write a letter to your friend.
In your letter
-describe the photograph you sent to the competition
-tell him/her about the exhibition where your photo is shown
-invite him/her to the exhibition

Dear Amy,

I won the first place in Lianyungang International Photography Competition. Over 300 people took part in this competition, so it is really not easy to win.

I took this photo when I was playing with my son in the park. My son had just picked up the stone and thrown it into the lake. So you can see the water splash. My son is smiling in this photo. I felt I was the happiest person in the world when I took this photo.

My photo is now shown in Tianjin Museum. People are able to see many great photos here and tickets are free. This museum is only 30 minutes from my apartment.

Are you free next Sunday? Why not go to the exhibition with me? That would be very interesting.

Hope to hear from you.

Best wishes,

Sophie

0427考试

You work for an international company. You enjoy this work but now you want to leave the company.
Write a letter to the manager of the company.
In your letter
- Tell the manager why you want to leave the company
- Explain what you have learnt from working at the company
- Say why you have enjoyed working for the company

Dear Mr White,

I am writing to tell you that I want to leave the company next month. I really enjoy the time here but I have to quit this job.

My son was born last year and I find it difficult to take care of him myself. So I have to move to Tianjin so that my mum could help me to look after my son.

I have learnt professional and competitive knowledge and skills in this company. For example, I have known how to write test cases as a software tester. Also, I know how to communicate and cooperate with my colleagues.

I have enjoyed working here because you could always help me whenever I encounter difficulties at work. I really feel lucky to have a manager like you. Also I have colleagues who are better than me, which makes me feel motivated to become as good as they are.

Yours faithfully,

Sophie
