nectionsiswhatdeterminesourmemories。此处需要一个动词作谓语，连接主语thestrengthoftheseconnections和宾语ourmemories。determine（决定，判定）符合句意。5.D解析：Thesetoolsallowscientiststoactuallyseewhichpartsofthebrainareactiveduringdifferenttasks。此处需要一个副词修饰动词see，表示“实际上，真正地”。actually（实际上）符合句意。6.B解析：certainregionsofthebrainthat/whichlightup。此处需要一个关系代词引导限定性定语从句，修饰前面的regions，并在从句中作主语。that和which在指代物时可以互换，但that更常用。7.A解析：Whatisknownforsureisthatitisahighlyadaptableorgan。此处需要一个名词性从句作表语，说明Whatisknownforsure的具体内容。that引导宾语从句，且在从句中不充当任何成分，只起连接作用。8.C解析：Thereisalwaysmoretodiscoveraboutthebrain.此处需要一个介词短语作定语，修饰前面的more。about（关于）符合句意。9.A解析：Thebrainoftentriestorepairtheaffectedareabycreatingnewconnectionsbetweenneurons。此处需要一个动词原形作动词tries的宾语，表示“试图修复”。repair（修复）符合句意。10.B解析：Theywonthegoldmedal,althoughtheirbrainshavefoundnewwaystofunctiondespitethedamage。此处需要一个连词引导让步状语从句，连接主句和从句，表示转折关系。although（尽管）符合句意。第二部分：句子改错1.B解析：删除also。在并列主语and连接的两个成分之间，通常不需要插入副词或其他修饰成分。also是副词，应删除。2.B解析：改为whentheyhavepermission。unless引导条件状语从句，表示“除非”，相当于ifnot。此处意为“如果他们有许可”，应使用when引导时间状语从句，并在从句中使用havepermission。3.C解析：改为andtheTVshowstarted。Havingfinishedmyhomework和theTVshowstarted是两个独立的句子，用逗号连接是逗号拼接错误。应改为并列连词and连接两个并列分句。4.D解析：改为werecoming。在if引导的非真实条件状语从句中，表示与过去事实相反的情况时，从句谓语动词应用过去式（be动词用were），had+过去分词。此处意为“如果我过去知道你来了”，主句动作发生在从句动作之前，应用过去完成时。5.D解析：改为was。neither...nor...连接两个主语时，谓语动词与靠近它的主语在数上保持一致。此处靠近neither，主语是theteacher（单数），谓语动词应用was。6.B解析：改为whose。that在引导定语从句时，若指人作先行词，且在从句中作主语或宾语，可以用that，但whose更常用且更自然，指代前面的人（themostintelligentperson）并作定语修饰theachievements。whoseachievementsare...符合句意。7.B解析：改为hadalreadyleft。bythetime引导的时间状语从句表示“到……时候为止”，主句和从句的动作通常发生在“到……时候为止”之前。此处意为“他们到达车站时，火车已经开了一个小时（离开了一个小时）”，主句动作发生在从句动作之前，从句应用过去完成时。8.C解析：改为whethertheyareathomeorschool。whether...or...连接两个并列的名词性成分，表示“或者”。此处意为“无论他们是在家还是在学校”，应用whethertheyareathomeorschool。9.A解析：改为Notonlydidhefinish...。Notonly放在句首引起倒装，句子应部分倒装，即将助动词did提到主语he之前。同时，主句中的并列结构应用Notonly...butalso...连接，且butalso后的成分与前面的成分在数上保持一致，应用hereceived。10.A解析：删除The。关系代词which引导的定语从句修饰前面的book，且在从句中作主语，指代物，不需要定冠词the。书是泛指的一本书，应用whichIborrowed...。第三部分：句子完成1.C解析：someonewhomhasexperience...。此处需要一个关系代词引导限定性定语从句，修饰someone，并在从句中作宾语。因为先行词someone是泛指的人，且在从句中作宾语，应用whom。关系代词在从句中作宾语时，可以省略。但此处为了清晰，保留whom。动词have应用现在完成时，表示拥有经验这个状态一直持续到现在。2.A解析：HoweverhardItry...。此处需要一个副词引导让步状语从句，修饰主句。however（无论如何）
