09职称英语理工类A级试卷？ 考试终于结束了，不知道大家能够想起来的有几题啊，欢迎大家讨论，提前评估成绩 我记着 1 阅读理解 Listening to Birdsong A male zebra finch1 chirps away2to 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. 词汇： finch n. 雀科鸣鸟 perk v. 使振作，使活跃 chirp v. ( 鸟 ) 鸣 morn n. 妈妈 ( 等于英国英语 mum) trill n.

A 选项 B 、 C 、 D 都不是答案，因为文章的第五段说，有配偶的雌性胸草雀更喜欢她们配偶的歌声，而没有配偶的喜欢的听雄性斑胸草雀为雌性斑胸草雀的歌。 3. B 第四段提到 …a male performing for a female audience, as if he was giving a concert. 所以，第七段中的 concert songs 即指雄性斑胸草雀为雌性斑胸草雀的歌。 4. D 文章的最后一段解释了什么是 directed communication, 即， when the communicator, or sender, focuses the message for a specific audience. 该段又举了母亲对婴儿说话的例子，说明这与雄性斑胸草雀为雌性斑胸草雀的歌同属 directed communication 。 5. B 文章所涉及的研究旨在发现雄性斑胸草雀歌声是否会在不同的情况下发生变化，其结果是，它们在为雌性斑胸草雀唱歌时，会改变声调和速度。这就是说，它们的歌声实际上是一种交流方式。所以应选择 B 。 查看更多13个回答 . 5人已关注
