| Dear Classmates, As young people, we don't always want to think about the past. 1 we often hear our grandfathers and grandmothers talk about cultural relics. They say we 2 protect some of these relics because they are important to our culture. 3 also say that these relics are important to us because they help us remember the 4 of our ancestors and respect what they have done. I'm sure you will 5 . After all, someday we will be 6 ourselves and will want our own children to protect them. So I have a plan for 7 the painting in the old temple, which is a fine cultural relic 8 in our hometown. It should be protected because it was painted by a 9 artist of the early Qing Dynasty. My plan is to get students to take a 10 to see it on a Saturday next month and then 11 some important people to join us. 12 , we can also write 13 about it for the town newspaper. Later, when others begin to 14 their help, perhaps we can 15 enough money to help the museum buy it. If you like my plan, please give me a note to your teacher. Thank you. | ||||
