10、nnounce后接从句。2Bdetermine“决定”；allow“允许”；persuade“说服”；forbid“禁止”。根据语境可知，B项符合要求。3D“我们乐意为人们解读梦境”。watch“观察”；study“研究”；describe“描述”；read“解读”。根据语境可知，D项正确。4B这里介绍了过去心理学家们了解人们的梦境所采用的办法，因此与过去有关。previously“过去，从前”。5C之前了解人们做梦情况的研究者为心理学家。因此A、B、D三项与语境不符。6ACerf博士希望能最终做到将人们对梦的记忆与大脑活动的电子影像进行比较。compare A with B“将A与B进行对比
11、”。7D根据语境及第一段的“record higher level brain activity”的暗示，答案为D项。8B根据语境判断，B项正确。“其中我们想回答的一个问题其实是我们什么时间做梦。”9A文章讲述了研究人员对梦境的研究，因此选A项。10C研究表明某些神经元或脑细胞与具体的物体或概念有联系。be linked with“与有关”。11Aparticular“具体的”，与前文的certain相呼应。12BCerf博士说，如果建立确认不同神经元与概念、物体和人物联系的数据库的话，他们将能够“读出实验对象的思想”。make up“捏造”；bring up“抚养”；pick up“学习”，
12、均与语境不符。13B根据语境推知，Roderick Oner是一位研究梦的专家。14C但是Roderick Oner博士说，用电子影像解释“复杂的梦境”是有限的。when it comes to“当涉及的时候”。15A通过手术将电极植入大脑。deep“深深地”，deeply“深刻地”。根据语境可知，A项正确。16C根据后面的“treat them for brain disorder”可知，研究者们是从有内植电极的患者那里得到数据的。17A不过，Cerf博士希望下一阶段人们将能够控制患者的脑部紊乱，但不再使用侵入性外科手术。本句与上一段的叙述有转折关系。18Bperiod“时期”；stage“
13、阶段”；circumstance“环境”；situation“局面”。根据前面的later判断，答案为B项。19D根据上文“read the subjects minds”可知，研究人员试图解读人们的思想。因此用“minds”。20C他说如果能够读懂昏迷患者的思想那可是“太棒了”，因为他们不能与医生交流。.阅读理解(共4小题；每小题2分，满分8分)阅读下面短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。Pupils dont often think their teachers really exist outside the school gates; now robot clas
