：过去分词作状语，表“被意外消息震惊”，主语“theteam”与“surprise”为被动关系，故选Surprised。9.A解析：“suggest”表示“建议”时，从句用虚拟语气“(should)+动词原形”，故选conduct。10.A解析：“Thenumberof...”作主语时，谓语用单数；“rise”为不及物动词，“raise”为及物动词，此处指数量上升，故选hasrisen。11.A解析：“Unless”意为“除非”，引导条件状语从句，符合“除非按时完成作业，否则不能参加旅行”的逻辑。12.B解析：定语从句中，“cover”与“thebook”为所属关系，用whose引导。13.A解析：“so+形容词+that”引导结果状语从句，故选so。14.C解析：现在分词完成式作状语，表“已经在山区教学五年”，与主句动作有时间先后，故选Havingtaught。15.A解析：“Notonly”位于句首时，主句需部分倒装，助动词提前，故选didtheyrealize。二、语法填空16.havebeenused解析：由“inrecentyears”可知用现在完成时，且“AI-poweredsystems”与“use”为被动关系，故填havebeenused。17.published解析：过去分词作后置定语，修饰“astudy”，表“被发表的研究”。18.of解析：“asuccessrateof95%”为固定搭配，意为“95%的成功率”。19.increasingly解析：副词修饰形容词“popular”，故填increasingly。20.to解析：“adaptto”为固定短语，意为“适应”。21.helping解析：现在分词作结果状语，表“AI系统提供反馈，从而帮助学生”。22.because解析：引导原因状语从句，解释“AI不应取代人类教师”的原因。23.where解析：定语从句修饰“field”，关系词在从句中作地点状语，用where。24.equipped解析：过去分词作后置定语，表“配备了先进传感器的自动驾驶汽车”。25.willaccount解析：由“by2030”可知用一般将来时，故填willaccount。三、短文改错1.go→went解析：lastweekend为过去时间，动词用过去式。2.Iandmyclassmates→myclassmatesandI解析：英语中人称代词顺序为“第二人称→第三人称→第一人称”。3.welcome→welcomed解析：上下文为过去时，动词用过去式。4.surprising→surprised解析：主语为“we”，用过去分词形式表“感到惊讶”。5.who→that/which解析：定语从句修饰“robot”（物），用that或which引导。6.careful→carefully解析：副词修饰动词“pick”。7.save→saved解析：并列结构“notonly...butalso”中，前后时态一致（过去时）。8.harvest→harvested解析：“vegetables”与“harvest”为被动关系，用过去分词。9.ahardwork→hardwork解析：“work”为不可数名词，不能用不定冠词a。10.day→days解析：“oneof+复数名词”为固定结构。四、长难句分析26.主句：Thenewlydevelopedsoftware
