6、 阅读下列短文，回答题。
Dear Felicia,
Thanks for staying in my house next weekend and taking care of my dog. I-Ielp yourself to the food in the fridge--you can take whatever you like. I borrowed some videos for you. They're on top of theTV. I picked out some action movies. I hope you like them. The VCR(录像带放录机) is easy to use, but remember to turn the TV down at 1 t :00 p.m. My neighbor doesn't like the noise. There are just a few other things to remember. Red's friendly, but please keep her away from my neighbor's dog.
They don't like each other. Her bowl is on the kitchen counter. Fill it up once a day with dry food.
Please walk her twice a day. When you go out, remember to turn on the answering machine. It's in the living room. The Sunday newspaper arrives at about 8:00 a.m. Pick it up early--sometimes it disappears ! When you leave for work Monday, just leave the keys with Mrs. Delgado next door. I'll get them from her when I get back.
Thanks again !
Ted
