Ⅳ.阅读理解:阅读下面材料,从所给的四个选项中选出能回答所提问题或完成所给句子的一个最佳答案。
Some of my family members, like my grandparents, don't live near me. They live in the city next to ours. During the winter holidays and some other vacations, my little sister and I will visit them with our parents. On other days, we often write letters to them.
One time, we decided to make a special letter to send to our grandparents. First, we took out lots of markers. We used copy paper and folded the pieces in half. Then, we drew a picture on the front. In the picture, we were making cookies with our grandparents. We coloured it all in. On the inside, we wrote down our wish list for the next holiday, including making cookies for them.
Another time, we wrote a letter to our cousin Peter and cut it up into large pieces. In the envelope, we included a note. The note explained that he should put the puzzle pieces（拼图块）together to read the letter. It was a lot of fun!
Writing a letter is a special way to stay in touch with your family. The letter doesn't have to be perfect. Just write something and put it in the mailbox. It will make your family members really happy!
