Tom, _______ at the door before you enter my room, please.

　 A. to knock B. knocking C. knocked D. knock

When you enter a supermarket, you see shelves full of food. You walk between the shelves. You carry a shopping basket with your food in it.

You probably hear soft, slow music as you walk between the shelves. If you hear fast music, you walk quickly. The supermarket plays slow music. You walk slowly and have more time to buy things.

Maybe you go to the meat department first. There is some meat on sale, and you want to find it. The manager of the supermarket knows where customers enter the meat department. The cheaper meat is at the other end of the meat department, away from where the customers enter. You have to walk by all the expensive meat before you find the cheaper meat. Maybe you will buy some of the expensive meat instead of the meat on sale.

The department selling milk and milk products such as butter and milk powder is called the dairy department. Many customers like milk that has only a little butter fat in it. One store has three different jars of low fat milk. One says “1 percent fat” on the jar. The second says “99 percent fat free”, the third says “Low fat” in big letters and “1%”in small letters. As you can see, all the milk has the same amount of fat. The milk is all the same. However, in this store the three jars of milk cost three different amounts of money. Maybe the customers will buy the milk that costs the most.

Most of the food in supermarkets is very pleasing. It all says “Buy me!” to the customers. The expensive meat says “Buy me” as you walk by. The expensive milk jar says “Buy me! I have less fat.”

I climbed the stairs slowly，carrying a big suitcase，my father following with two more. By the time I got to the third floor，I was　1　and at the same time feeling lonely. Worse still，Dad　2　a step and fell，sending my new suitcases 　3　down the stairs. “Damn!”he screamed，his face turning red. I knew trouble was ahead. Whenever Dad's face turns red，　4　！

How could I ever　5　him to finish unloading the car without screaming at me and making a scene in front of the other girls，girls I would have to spend the rest of the  6  with？Doors were opening and faces peering out(探出)，as Dad walked with difficulty close behind. I felt it in my bones that my college life was getting off to a(n)　7　start.

“Enter the room quickly，”I thought. “Get him into a chair and calmed down.” But then again，would there be a chair in Room 316？Or would it be a(n)　8　room？

Finally I turned the key in the lock and   9   the door open，with Dad still   10    about a hurting knee or something. I put my head in，　11　the worst. But to my　12　，the room wasn't empty at all！It had furniture，curtains，a TV，and even paintings on the walls.

And there on a well??made bed sat Amy，my new roommate，dressed neatly. Greeting me with a nod，she said in a soft voice，“Hi，you must be Cori.” Then，she　13　the music and looked over at Dad. “And of course，you're Mr.Faber，”she said，　14　.“Would you like a glass of iced tea？”Dad's face turned 15　 less red before he could bring out a “yes.”

I knew then that Amy and I would be friends and my first year of college would be a success.
