The Allendale Cultural Center has expanded its arts program to include classes for young adults.Director Leah Martin announced Monday that beginning in September，three new classes will be offered to the Allendale community.The course titles will be Yoga(瑜伽) for Teenagers；Hip Hop Dance：Learning the Latest Moves；and Creative_Journaling_for_Teens：Discovering_the_Writer_Within.The latter course will not be held at the Allendale Cultural Center but instead will meet at the Allendale Public Library.
Staff member Tricia Cousins will teach the yoga and hip hop classes.Ms.Cousins is a skilled choreographer (舞蹈指导) as well as an experienced dance educator.She is a Master of Arts in dance education from Teachers College，Columbia University.The journaling class will be taught by Betsy Milford.Ms.Milford is the head librarian at the Allendale Public Library as well as a columnist(专栏作家) for the professional journal Library Focus.
The courses are part of the Allendale Cultural Center’s Project Teen，which was organized by Leah Martin，Director of the Cultural Center.According to Martin，this project is a direct result of her efforts to make the center a more necessary part of the Allendale community.Over the last several years，the number of people who have visited the cultural center for classes or events has steadily declined.Project Teen is primarily funded by the McGee Arts Foundation，an organization devoted to bringing arts programs to young adults.The other members of Project Teen are two students at Allendale’s Brookdale High School and three adults with backgrounds in education and the arts.
The creative journaling class will be cosponsored by Brookdale High School，and students who complete the class will be given the opportunity to publish one of their journal works in Pulse，Brookdale’s student literary magazine.Students who complete the hip hop class will be qualified to participate in the Allendale Review，an annual concert sponsored by the cultural center that features local actors，musicians，and dancers.
All classes are scheduled to begin immediately after school，and transportation will be available from Brookdale High School to the Allendale Cultural Center and the Allendale Public Library.For more information about Project Teen，contact the cultural center’s programming office at 9880099 or drop by the office after June 1 to pick up a fall course catalog.The office is located on the third floor of the Allendale Town Hall.
小题1:The underlined title of the course in Paragraph 1 implies that ________.
A．teenagers do not have enough hobbies

A．More and more people are coming to the center.
B．Tricia Cousins is available to teach courses in the fall.
C．Community organizations were ignoring local teenagers.
D．Leah Martin wants to make the center more important for the community.小题3:What does the text mainly tell us?
A．The needs of young adults in Allendale.
B．Leah Martin’s personal ideas about Project Teen.
C．The center adds three new classes for young adults.
D．The center is granted by the McGee Arts Foundation.小题4:Which of the following ways is the text organized?
A．In order of space，from the near to the far.
B．In order of time，from the past to the future.
C．The most important information first，followed by background and details.
D．The background first，followed by the most important information and details.
| 阅读下面短文，回答文后问题。 磁共振现象为成像技术提供了一种全新思路：将人体置于特殊磁场中，用无线电射频脉冲激发人体内氢原子核，引起氢原子核共振，并吸收能量；在停止射频脉冲后，氢原子核按特定频率发出射电信号，并将吸收的能量释放出来，被人体外的接收器收录，经电子计算机处理获得图像。 许多原子核的运动类似“自旋体”，不停地以一定的频率自旋。如果把物体放置磁场，原子核可以在磁场中旋转。磁场的强度和方向，决定原子核旋转的频率和方向。在磁场旋转的原子核有一个特点，即可以吸收频率与旋转频率相同的电磁波，使原子核的能量增加；当原子核恢复原状时，就会把多余的能量以电磁波的形式释放出来；用适当的电磁波照射它，然后分析它释放的电磁波，就可以得知构成这一物体的原子核的位置和种类，据此绘制物体内部精确的立体图像。 水约占人体体重的2/3，在人体不同组织和器官中，水分比例不一样。有趣的是，许多疾病的病理过程会导致水分变化，而这种变化恰好能在磁共振图像中反映出来。因为水由氢原子和氧原子构成，氢原子核能够起到类似显微指南针的作用。在身体暴露于一个强磁场，无线电波的脉冲传递到位后，原子核的能量便开始改变。在脉冲之后，原子核返回先前的状态，—一个共振波便发射出来。这样，原子核振荡的微小变化就可以探测出来。通过先进的计算机编程，可以创建一个包括不同水含量和水分子运动的反映组织化学结构的三维图像。从而在被观察的身体部位产生非常清晰的组织或器官图像，有利于弄清疾病的病理变化。 由于磁共振成像与X射线、CT等原理完全不同，故对人体没有兵贵神速，几乎适用于全身各系统不同疾病的检测；尤其对颅脑、脊椎和脊髓疾病的检测，更能显示它优于CT。它可以不用血管造影剂即显示血管结构，故对血管、肿块、淋巴结和血管结构之间的鉴别更加独到。它对软组织的分辨能力高于CT数倍，能够敏感地检测出组织成分中水含量的变化，因而常比CT更有效亦更早地发现病变。磁共振成像技术的优越性，使得这项新的影像学技术越来越显示出强大的生命力。 磁共振成像技术是2003年诺贝尔生理学或医学奖表彰的一项奠基性成果。瑞典卡罗林斯卡医学院把 2003年诺贝尔生理学或医学奖授予现年74岁的美国科学 * * 罗·劳特伯和现年70岁的英国科学家彼得·曼斯菲尔德，以表彰他们在磁共振成像技术领域作出的突破性贡献。诺贝尔奖评选委员会认为，用一种精确的、非入侵的方法对人体内部器官进行成像，对于医学诊断、治疗和康复非常重要。两位科学家的成果对磁共振成像技术的问世起到了奠基性作用。这篇阅读选材可以说是紧扣科技发展的脉搏，具有很强的时代感，对引领当代高中生及时关注世界重大科技发展信息，扩大自然科学阅读面具有较好的启示作用。 (《物理学与医学交叉碰撞出诺贝尔奖》(删改)，选自《大众科技报》，2003年10月14日) |
