听力原文：On today's program, I'll talk to Morris Stevenson, whose first film excited the audience. He also received excellent reviews from numerous critics. I, personally, would also like to give two thumbs up to this one! It is unusual for a new filmmaker to receive so much attention after directing just one film, but clearly film critics feel he has a certain gift to create something. He's visiting the city this week to speak to students at Green Diamond film school, and we are fortunate he has added us to his busy schedule, and is spending time with us as well. Thank you for joining us in this studio, Mr. Stevenson.

听力原文：The complex vocalizations of songbirds are learned, not inherited.Some even have regional accents. Wrens, thrushes and other songbirds don't hatch with their impressive musical talents. They learn to sing their extensive repertoires by listening to others of their kind.Donald Kroodsma is the author of a new book, The Singing Life of Birds. Kroodsma says many birds seem to come naturally equipped with basic sounds and even some very simple songs. The eastern wood-pewee is an example. "We've done some experiments showing that those songs are pretty much encoded in the DNA.But as a result, it's a pretty limited repertoire of, oh, in the eastern wood peewee, of up to three different songs. But all the songbirds, when we think of songbirds, we think of wrens and warblers, robins, thrushes, sparrows, all the birds that make so much racket, these are the songbirds that have very special groups of neurons in the brain, and most of them imitate precise details of songs just like you and I learned our native language." Kroodsma says birds even share our tendency toward regional dialects. "When birds learn songs at a particular location and stay around at that location, regional dialects tend to develop. They have the same kind of dialects that develop in human speech." Kroodsma says he recently took a long bike trip, from the Atlantic Coast through Virginia, Kentucky and Illinois. He says the accents and dialects of both people and birds changed along the way.

听力原文：Thank you for coming today to our focus group session. I' m Turmila Dreifort, director of product development. As you know, we asked each of you to participate in this discussion because you purchased ABE mattresses from our company in the last six months. We want to know what you think of them. Before we begin the discussion, I'm going to hand out a questionnaire. It has just a few basic questions about the quality of your sleeping experience since you bought our mattresses. The main thing we want to know is "Do you sleep better now？" and if you do, which we certainly hope is the case, " How much better？"
