Humans have vocal cords(声带), muscles in the top of the throat, which vibrate(振动) to produce sound. That unique part helps people control their voices well enough to produce sounds that form spoken language. However, unlike all the other studied primates, humans don’t have vocal membranes. To find out how vocal membranes affected spoken sounds, a team from Kyoto University took throats from monkeys that had died of natural causes and put the parts into devices, pushing air through the throats to see how the vocal cords and membranes would react. In the experiment, the researchers found that their vocal membranes and vocal cords vibrated together. Researchers said these vocal membranes make it harder for other primates to control the voices they make. Without these membranes, humans’ vocal source is more balanced, allowing better voice control and production of long and balanced voices. A key thing that distinguishes human speech from animal sounds is our control over the sounds we make. In humans, that sort of unpleasant voices can happen when we put extreme amounts of pressure on our voice, like baby crying and adult screaming. But those are rare cases. Researchers also said that our mouths and tongues could help control the voices. They are the basis of human languages. 1. Why does the human voice sound less unpleasant? A. Humans have no vocal membranes. B. Vocal cords of humans are very narrow. C. Muscles in the human throat can hardly be controlled. D. Humans’ brains are structured differently from other primates. 2. How did the researchers conduct the study? A. By exploring the history of human evolution. B. By referring to previous researches on primates. C. By observing monkeys’ vocal cords and membranes. D. By comparing the voice patterns of different animals. 3. What is Paragraph 4 mainly about? A. A doubt about the research process. B. The importance of the research findings. C. Further explanation of the research results. D. The potential application of the research methods. 4. Which can be the suitable title for the text? A. Why humans cry or scream? B. How primates make sounds? C. How primates develop languages? D. Why humans’ voice sounds pleasant? 五、（2022-2023学年下学期·湖南长沙高一期末）语法填空 Dumplings are the most essential and popular food for Chinese people, especially in northern China.

(为了弄清声膜是如何影响说话声音的，一个来自京都大学的研究小组从自然死亡的猴子身上取出喉咙，把这些喉咙放入设备中，将空气推入喉咙，观察声带和声膜是如何反应的)”可推知，研究人员是通过观察猴子的声带和声膜来进行实验的。故选C。 3. 主旨大意题。根据第四段“Researchers said these vocal membranes make it harder for other primates to control the voices they make. Without these membranes, humans’ vocal source is more balanced, allowing better voice control and production of long and balanced voices. A key thing that distinguishes human speech from animal sounds is our control over the sounds we make.(研究人员说，这些声膜使其他灵长类动物更难控制它们发出的声音。没有这些膜，人类的声源更加平衡，允许更好的声音控制和产生长而平衡的声音。区分人类语言和动物声音的一个关键因素是我们对自己发出的声音的控制)”可知，第四段主要进一步解释了研究结果。故选C。 4. 主旨大意题。通读全文，尤其是第一段“Humans’ voice sounds more pleasant than that of primates (灵长类动物) because we don’t have vocal membranes (声带膜), a new study suggests.(一项新的研究表明，人类的声音听起来比灵长类动物更令人愉悦，因为我们没有声膜)”可知，文章主要介绍了一项新的研究表明，人类的声音听起来比灵长类动物更令人愉悦，因为我们没有声膜。由此可知，D项“为什么人类的声音听起来很悦耳？”适合作文章标题。故选D。 五、（2022-2023学年下学期·湖南长沙高一期末）语法填空 Dumplings are the most essential and popular food for Chinese people, especially in northern China.
