I go abroad for further studies half a year ago. I received a lot of present. All were wrapped in color paper. Among them was two presents which really interested in me. My sister bought me the book with color pictures about body language and with words about customs of differently countries in it. My brother gave me a note saying, “My present for you has been put in my bedroom.” While I hurried into my bedroom, I found a box in it. Open the box, I found a pocket computer. I was very glad. I understood these two presents would be great help to me in improving my English.
