    I sat down at my desk and tried to focus on my studies. In just seven more days, finals would be over and all the students in my college 1 would be leaving to   go home-2 me. I would be moving 3 to another dormitory for the Christmas break.

    I had no 4. I was a student from Pennsylvania attending college in Utah and my family of ten couldn't 5 to pay for my ticket home. The only 6 I was even able to attend college was that I had received several scholarships.

    I started at the white snow dancing through the air. This would be my 7 Christmas away from home. I felt so 8 that I could weep. 9 I swallowed down the ache that was rising in my throat, my phone rang suddenly. I reached over and picked it 10.

    “Hello?”

    “Hi, Teddi. This is Elsie.” What was my boss from high school grocery job 11 me for? “All the workers here 12 that you weren't able to make it home this year.13 we bought you a ticket. You're coming home!”

    I screamed.

    Fifteen minutes later I was off the14and jumping up and down for 15. Neighbors came over to see what the 16 was all about.

    “I'm going home for Christmas! My17 at my high school job bought me a ticket!” I told them.

    Christmas 18, I was awoken by laughs and screams of joy. The smell of roasting turkey and the wrapping paper（包装纸）that grew higher and higher filled me with love and 19. The kindness of some special fiends 20 me to have the best Christmas ever.

    Hello. I'm Jan from Mrs. Lake's class. My class wants to work together to help the public. We think we have found a great way to do this. Last month we did a class project on the highways near our town. We learned about the Adopt-a-Highway Program. This program brings people together to pick up litter along the roads. We think it would be a great idea for all students in our school to join the program and adopt（收养） a highway.

    Adopting a highway is not like adopting a pet. When a highway is adopted, only part of the highway is cared for by a group of people. The group agrees to work every week to keep its part of the highway clean. Each group gets its own sign that has the name of the group printed on it. The sign is put up at the side of the road . This sign lets drivers know who is keeping that area of the road clean.

The Adopt-a-Highway Program is a great way for people to help their environment look nicer. Also, the government does not have to send out as many road workers. This saves money. Finally, people may try harder to keep roads clean if they see people, especially teenagers like us, cleaning them up.

     We will need helpers to care for our adopted highway. If you want to feel great and keep our roads clean，please come with your parents to the meeting next week. We will meet in Mrs. Lake's room on Wednesday at 6:00 P.M. At the meeting, we will talk about which roads are the dirtiest as a result of people's unkind acts. Then we'll try to pick an area to adopt and clean.

    I look forward to seeing you at the meeting. Remember to keep our roads clean!
