12. When school started on that warm August day, I threw myself into everything I did, including playing volleyball. I decided to become beautiful, or at the very least, thin. I stopped eating completely. Soon I began losing weight, which thrilled me, and I even grew to love the tiredness and lightheadedness (头晕) that came with my poor diet, for those feelings meant that I was winning.
As the season went on, things became tense between my head volleyball coach, Coach Smith, and me. She felt that something was wrong with my health. She talked with me about my eating and was angry that I wouldn't listen to her when she tried to make me eat. She tried to persuade me in a determined way and so we fought constantly. Then my hunger started to affect my performance. I was so tired that practice was becoming a struggle. One afternoon, with hurt in her eyes, Coach Smith asked me what I had eaten and I told her nothing yet. She looked at me, disappointment in her eyes, knowing she couldn't make me stop, and walked away.
A couple of weeks later I attended a formal dinner for our volleyball team. I stood there as my coach said something nice about me. I realized then that I had ruined my senior year by being disrespectful, and that I had probably ruined hers as well. So that evening I wrote her a letter apologizing to and thanking her.
Then one Saturday, as I was reading in the library, I felt someone gently take my arm and say softly, "Lynn Jones, how are you doing " I looked up and saw the familiar face. "Thanks for the letter," she said. "It meant a lot."
When I think of a coach, I think of someone above me, someone who gives instruction -- not a friend. But Coach Smith is different, and, like any other good friends, she dealt with my problem in a determined way even when I hated her for it at that time. I didn't deserve her kindness, but she gave it anyway. I will forever be grateful for her help, and now for her friendship.

D.She wanted to build a close relationship with Coach Smith.

12. NAO, the first robot able to show feelings, has been created by a European research team. When NAO is sad, he lowers his head and looks down. When he's happy, he raises his arms for a hug. Nothing is out of the ordinary, except that NAO is a robot.
"We're modelling the first year of life," says Lola Canamero, a computer scientist at the University of Hertfordshire. "The feelings are shown through physical gestures and body movements rather than facial or verbal(言语的) expressions."
In the future, says the scientist, robots are likely to act as companions, provide support for old people, and help people shop online. In these situations, the display of emotions, will be important in making the interaction(相互作用) more natural and comfortable.
NAO has been programmed to copy the emotional skills of a one-year-old child. It can memorize faces, and knows the basic rules of good and bad. Based on these it can decide how to react to what is going on. The actions going with each feeling are pre-programmed, but NAO decides for itself when to display them.
NAO is also programmed to have different personalities. A more independent robot is less likely to call for help when exploring a room, while a more fearful robot will show distress if it finds something in the room that may be harmful.
Canamero's team will take its emotional programming forward into medical applications. Part of the project will look at ways to use robots in hospitals to support the roles of doctors, nurses and parents. Children might find that a small, friendly-looking robot that can understand their emotional states makes them less anxious. "We want to explore different roles—the robots will help the children to understand their treatment and explain what they have to do. We want to help the children to control their anxiety," she says.
1.According to the text, what do we know about NAO
A.It displays different feelings in different situations.
B.It is able to imitate adults, emotional displays.
C.It can remember people's feelings.
D.It learns emotions from facial expressions.
2.What can we learn from the text
A.Scientists worked on facial and spoken expressions to create NAO's emotions.
B.The time when NAO displays feelings has been pre-programmed.
C.Emotional programming is used in medicine production.
D.Robots with emotional skills can help children feel more comfortable.
3.What does the underlined word "distress" in Paragraph 5 probably mean
A.Courage. B.Anxiety. C.Anger. D.Satisfaction.
4.What is the text mainly about
A.The relationship between humans and robots.
B.The roles that robots play in different fields.
C.The first robot able to show feelings.
D.The long history of robots.

解析：①主旨句。根据下文"Small portable radios didn't sound good(小的便携式收音机听起来不太好)"及第三段中的"Sony introduced a product called the 'Walkman'(索尼公司推出了一款名为'随身听'的产品)"可知, 本段主要是介绍随身听问世以前人们的听歌方式, G项Before the Walkman came out, there wasn't a good portable way to listen to music.(在随身听问世之前, 还没有一种好的便携式听歌方式)切题。故选G。
②细节句。根据上文The "walk" part of the name was important.可知, 设空处应是对这一内容的进一步阐释, 故E项It meant that you could listen to your own music as you walked around.(这意味着你可以边走边听自己的音乐)符合语境。故选E。
③细节句。根据上文"Compared to the headphones we have now, the quality wasn't good. But back then, the sound amazed people.(和我们现在的耳机相比, 随身听的音质不是很好。但在那时候, 它发出的声音让人们惊叹不已)"可知, 设空处应是对前面句子的补充, 进一步说明这令人惊叹的声音, 故C项It almost felt like the music was playing inside your head.(那感觉几乎就像音乐在你脑子里播放)符合语境。故选C。
④过渡句。根据上文"the Walkman was hugely popular(随身听非常受欢迎)", 再根据下文"But whoever made the device, most people kept using the name 'Walkman'.(但是无论谁制造了这种设备, 大多数人都沿用'随身听'这个名字)"可知, 设空处与制造随身听相关, 故B项Soon other companies were imitating Sony's device.(很快, 其他公司开始模仿索尼的设备)与上下文衔接紧密。故选B。
⑤细节句。根据上文"On a phone or other music player today, you might have hundreds or thousands of songs. But the selection on the Walkman was much more limited.(在今天的手机或其他音乐播放器上, 你可能有成百上千或成千上万首歌曲。但是随身听的选择要少得多)"可知, 设空处所述内容应与随身听提供的选择有限有关, 故A项The Walkman then could only play cassette tapes.(当时随身听只能播放盒式磁带)符合语境。故选A。
12.答案：1-4 ADBC
解析：1.细节理解题。根据第一段中的When NAO is sad, he lowers his head and looks down. When he's happy, he raises his arms for a hug.可知, 当NAO伤心时, 它会低下头, 当它开心时, 它会伸出手要求拥抱, 这说明NAO能在不同情况下表达不同的情绪。故选A。
2.细节理解题。根据第六段中的Children might find that a small, friendly-looking robot that can understand their emotional states makes them less anxious.可知, 如果孩子们有一个小小的、友好的又能够理解他们情感状态的机器人陪着的话, 他们可能就不会那么焦虑了, 也就是说具有情感技能的机器人可以帮助孩子们感觉更放松。故选D。
3.词义猜测题。前面提到一个更独立的机器人在探索房间时很少寻求帮助, 是独立完成任务的。句中的while表示对比, 由此可以判断, 后面是说一个胆怯的机器人如果在房间里发现可能有害的东西时会表现出焦虑(的情绪)。故选B。
4.主旨大意题。根据第一段第一句NAO, the first robot able to show feelings, has been created by a European research team.和全文内容可知, 本文主要介绍了由一个欧洲研究团队发明的第一个能够表达感情的机器人NAO。故选C。
