2.考查细微环节理解。依据GreenheltontheGo部分的"Registrationisrequired.Toregister,pleaseemailnaturecenter@sigreenbelt.orgbeforeAugust14"可知,参与该活动须要提前登记,因此选D。

3.考查细微环节理解。依据第四项活动的"Thethreemilesofnearbynaturalshorelineareasandybeach...foundhere"可知,这里是喜爱沙滩、海岸、大海的人的天堂,所以喜爱大海的人应当给TheSouthPolealWardsPoint活动的联系邮箱发邮件询问信息,因此选D。

4.考查细微环节理解。依据第一段的"VisitourpagetofindsomeofthebestfreewalkingtoursacrossNewYorkCity"可知,这四项远足活动都是免费的,因此选B。2答案及解析：答案：1.B;2.C;3.D;4.A解析：1.考查写作意图。第一段对传统的学生上学的情景和日益受欢迎的虚拟学校的学生上学的情景进行对比,其次段至文末都在讲虚拟教化,故首段的作用是引出本文的话题——虚拟教化。故选B。

2.考查数字计算。依据题干中的信息定位答案在其次段末句,由该句可知,虚拟学校的注册学生人数在2015—2025学年和2024—2025学年间增加了17000,2024—2025学年注册人数增加到295518,故答案为295518-17000=278518。。

3.考查推理推断。依据题干中的ArizonaVirtualAcademy定位答案在第三段。依据本段中Dr.KellyVanSande的话可知,该虚拟学校始终在改进他们的平台和技术,以确保能够跟上不断改变的趋势,不仅仅是跟上教化的改变趋势,还要跟上技术的改变趋势。由此可推断,该校的平台和技术很先进。故选D。

4.考査观点看法。依据题干中的CarrieFaulkner定位答案在最终一段。CarrieFaulkner选择让她的两个孩子上虚拟学校,并且依据她说的"我真希望在我上学的时候也有虚拟教化,那就太棒了”也可推断,CarrieFaulkner对于虚拟教化持确定、支持的看法。3答案及解析：答案：1.B;2.A;3.D;4.A解析：1.推断题。依据第2、3段可知，作者提到协和式超音速客机是为了强调声爆的负面影响。2.主旨题。通读第4段可知，该段介绍了这款新式飞机的一些基本资料。3.词义推断题。依据画线词所在句的句意和最终一句中的Ifwegetapproved可推断,endorsement意为“同意;认同”。4.主旨题。本文主要介绍了美国国家航空航天局新研发的一款飞机。4答案及解析：答案：1.A;2.D;3.C;4.C解析：1.主旨大意题.第一段主要描述了Amanda运用驾驶模拟器的情景.作者主要是通过这个生动的事例来展示这台驾驶模拟器的详细操作状况和功用,以引入话题,故选A.

2.细微环节理解题.依据第三段其次句"Theysaidtheywantedtohelpstudentslearnaboutthedangersofdrivingdrunk,whiletexting,orwhiletalkingonthephone."可知,驾驶模拟器项目被引入罗斯福中学是为了让学生意识到分心驾驶的危害.故选D.

3.细微环节理解题.依据第四段Thesimulatorisbasicallyacomputerprogram.Likemanycomputergames,itwasahitwiththestudents可知,驾驶模拟器吸引了学生对计算机程序的爱好.故选C.

7答案及解析：答案：1.which2.raising3.their4.isbursting5.wouldpray/prayed6.Traditionally7.foods8.cut9.the10.that解析：本文是一篇说明文,主要介绍了农历二月二时中国的传统风俗。1.which考査定语从句。分析该句结构可知,空处引导非限制性定语从句,先行词为"DragonHeads-raisingDay",空处在从句中作主语,故用which引导该定语从句。2.raising考查非谓语动词。该句主语“Thedragon"和动词raise之间是逻辑上的主谓关系,在此处作伴随状语,故用其现在分词形式。3.their考査代词。空处修饰后面的名词"heads",故用形容词性物主代词their,表示"它们的头"。4.isburning考査固定用法。依据常识并结合语境可知,也许就是这个时候,大地生气勃勃。此处考査固定用法beburstingwithsth.,表示"充溢某物”;且该句主语为"thee
