    【题目】 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 modeling the first years of life,” says Lola Canamero, a computer scientist at the University of Hertforshire. “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 such uses, the display of feeling will be important in making the interactions (交往) 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 Nao_______.

    A.displays different feelings in different situations

    B.is able to copy adult emotional displays

    C.can remember people’s feelings

    D.learns feelings 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 can’t robots do in the future according to the scientist?

    A.They can work as your companion.

    B.They can aid old people .

    C.They can shop with you.

    D.They can show their feelings.

    【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.

    【题目】 The mayor of Flint offered Miss Michigan Emily Sioma high praise on Tuesday for speaking out at this weekend's Miss America conference about the city's water crisis.

    “I was really excited for her to do that," Mayor Karen Weaver told TMZ. “I think she was very brave because so many times you say who you are and where you're from and just general information. For her to take that opportunity and use her platform and use her voice to speak up about what‘s going on in Michigan and in Flint, in particular, was just amazing. ”

    Emily Sioma,24,introduced herself on stage on Sunday by saying,“From the state with 84 percent of the U. S. fresh water but none for its residents to drink. I am Miss Michigan Emily Sioma.” The brief ‘speech was a reference to Flint, a town with lead-filled drinking water.

"
