they teach students as teachers. More and more students like studying and the other robot teachers were also sent out. They can teach math, science and art. The researchers found that the Englishteaching robots helped raise interest in the language and helped the students feel more confident. “ Telepresence” robots are controlled by an English and are equipped with a microphone and video camera. Many people think we can use these robot teachers in the village far away from the cities so that the children in these areas can also get better education. The government has expressed great interest in robots to give rural school children more learning chances. I think in the future we can see more and more robot teachers working with the students. But I think the robot teachers can’ t replace the real teachers. What’ s your opinion? 45. Where do these robot teachers work now? A. In shops. elementary schools C. In universities. middle schools. 46. Why do school children like the robotic teachers more than the ordinary ones? A. Because robot teachers are very clever. B. Because they know much knowledge. C. Because they are very kind to the students. D. Because they never feel tired. 47. How long have the Englishteaching robots been teaching? A. Five weeks. B. Six weeks. C. Seven weeks. D. Eight weeks. 48. From the passage we know that ____________. A. there will be more robot teachers in schools B. there will be no human teachers in the future C. South Korean schools have too many robot teachers D. there are no teachers in the village far from cities C If you39。 re ever apart from your children, a new study says just talking on the phone will help just as much as a hug (拥抱 ). If you39。 re a parent who spends long hours on the job, you probably feel sorry for spending so much time away from your kids. But the results of a new study show that a mother39。 s voice alone can be just as forting to an anxious child as physical contact (接触 ). In an experiment, researchers from the University of Wisconsin Madison asked a group of girls between the ages of 7 and 12 to solve math problems in front of judges — a stressful situation for anyone. Before the girls were set to give their answers, the researchers measured their levels of two hormones(荷尔蒙 )： cortisol，which goes up during stressful periods,and oxytocin, the “ love” hormone, which goes down at the same time. After the girls finished the problems, some of them got to meet up with their mothers right away. The moms came in and hugged the girls. Another group of the girls didn39。 t see their mothers, but received phone calls from them, in which their mothers told them how well they39。 d done. The final group had no contact with their mothers, but instead watched an animal movie, March of the Penguins. Finally, the girls39。 hormone levels were measured again. Although the movie was interesting, it did nothing to reduce the children39。 s anxiety— but, surprisingly, both the physical contact and phone calls from their mothers had the same effect on reducing the girls39。 stress levels. So, no matter how old you are, if you39。 re feeling stressed about something in your life, a phone call to Mom might be just the key to help you feel better. 49. If a girl is under stress, _______. A. she can’ t solve math problems B. she will have high levels of hormone C. oxytocin will remain at a high level D. cortisol will go up with oxytocin down 50.

The girls39。 levels of hormones were measured. d. The girls were divided into three groups. A. bcda B. dbca C. cbda D. dcba 51. From the passage, we can infer that _______. A. it is easy for girls to solve math problems B. the girls who had watched th。
