The exam is finally over. I don’t know how many questions you can think of. Everyone is welcome to discuss. To evaluate the results in advance, I will remember 1 Reading Comprehension Listening to Birdsong A male zebra finch1 chirps away2 to himself. Suddenly he notices a female bird nearby. He realizes he has an audience and immediately changes his song. Can the female tell the difference in his performance? According to a new study, the female zebra finch knows. And she prefers the special trills he creates when he sings to her. A male zebra finch changes his song when singing to a female in ways that people can barely detect. But ~the female finch can tell the difference. Scientists had noticed slight variations in the songs of mal~ zebra f'mches based on whether they were singing alone or whether there was a female (and potential mate) nearby. With an audience, the males sped up the pace of their songs and controlled the notes they used. For this study, researchers Sarah C. Woolley and Allison Doupe at the University of California, San Francisco decided to focus attention on the listening females, which have not been well studied in the past. In the study, Woolley and Doupe set up ,a long cage with a sound speaker at each end. One broadcast the sound of a male zebra finch singing to himself, like someone singing in the shower. The other speaker broadcast a male performing for a female audience, as if he was giving a concert. Female birds were placed between the two speakers. Some of the birds had mates, others didn't. The females shifted around a bit, and then most of them hopped over to sit beside just one speaker. All the birds that made a clear choice liked songs meant for a female audience, even if they'd never met the male. Mated females also had a chance to listen to two different performance songs, one from an unknown male, and one from their mate. They spent more time listening to the concert version of their mates' songs. This suggests that after a while, females learn to recognize--and prefer--the songs of their mates. Scientists then studied the brains of the females. They found certain areas of the brain perked up3 when the birds listened to the concert songs. These brain areas may be involved in recognizing and evaluating the songs, and storing the memories of them. This research deals with what's called directed communication, when the communicator, or sender, focuses the message for a specific audience. One example is the way moms speak to their babies. Mothers around the world use the same sort of high'pitched4 sing-song chatter, and the babies respond best to those sounds. Songbirds are one of the only other species known to learn their communication, in this case their songs. Vocabulary: finch n. Finch songbird perk v. To cheer up, to make active chirp v.

C) Zebra finches and their life. D) Enjoying birdsongs. Answers and solutions: 1. C The second sentence of the first paragraph of the article tells us that a male zebra finch will change the tone of his voice whenever he notices a female zebra finch listening to him singing. None of the other options are what the paragraph means. 2. A. Options B, C, and D are not answers because the fifth paragraph of the article says that female zebra finches with mates prefer the songs of their mates, while those without mates like to listen to the songs of male zebra finches to female zebra finches. 3. B The fourth paragraph mentions...a male performing for a female audience, as if he was giving a concert. Therefore, the concert songs in the seventh paragraph refer to the songs of male zebra finches for female zebra finches. 4. D The last paragraph of the article explains what directed communication is, that is, when the communicator, or sender, focuses the message for a specific audience. The paragraph also gives the example of a mother talking to her baby, explaining that this is the same type of directed communication as the song of a male zebra finch to a female zebra finch. 5. Article B The study involved in the study aimed to discover whether the songs of male zebra finches change under different circumstances. As a result, they change the pitch and speed of their voices when singing to female zebra finches. This means that their singing is actually a form of communication. So B should be chosen.
